EMBODIMENT 1

[0042] Referring to FIGS. 1-14, this embodiment provides a spring module configured to be compressed for storage, the spring module comprises a base 1 and an upper cover 2, a spring 3 is disposed between the base 1 and the upper cover 2, and an outer surface of the spring module is wrapped with a flexible cloth sleeve 4; a connecting member 5 is further disposed on a waist portion of the spring module, and adjacent spring modules are connected together to be spliced into an elastic module with a size required by the user through the connecting member 5; and an outer side of the elastic module is wrapped with a decoration cloth to be then used as an elastic mattress.

[0043] A lower end surface of the upper cover 2 comprises a first locking structure 21, an upper end surface of the base 1 comprises a second locking structure 11, the first locking structure 21 and the second locking structure 11 face each other and are disposed in a chamber of the spring module, and the spring module is compressed to enable the first locking structure 21 and the second locking structure 11 to be buckled together in a vertical direction to lock the spring module in a compressed state; and the spring module rotates to release the first locking structure 21 from buckling to the second locking structure 11 so as to release the spring module.

[0044] Specifically, the upper end surface of the base 1 forms a protruding cavity structure 111, which has a cylindrical shape, along a compression direction of the spring module, an outer edge of a top of the protruding cavity structure 111 comprises protruding edges 112, which are discontinuous, as the second locking structure 11, and gaps 113 are defined between adjacent protruding edges 112; the lower end surface of the upper cover 2 comprises buckling hooks corresponding to the protruding edges 112 one to one and at intervals and used as the first locking structure 21;

[0045] Surfaces of the protruding edges 112 facing the base 1 form positioning surfaces 1121, the protruding edges 112 are gradually widened in a vertical downward direction to enable surfaces of the protruding edges 112 facing the upper cover 2 to form inclined surfaces 1122, the buckling hooks comprise connecting portions 211 and hook portions 212, ends of the connecting portions 211 are connected to the lower end surface of the upper cover 2, and the hook portions 212 are disposed on inner sides of the connecting portions 211 and face a center of the protruding cavity structure 111; and

[0046] When the spring module needs to be locked in the compressed state, the upper cover 2 and the base 1 are held by both hands to compress the spring module by a force, at this time, the buckling hooks on the upper cover 2 slide along the inclined surfaces 1122 of the protruding edges 112, and the inclined surfaces 1122 enable the buckling hooks to generate an acting force away from the center of the protruding cavity structure 111 to drive the buckling hooks to extend; when the buckling hooks slide downward to be separated from the inclined surfaces 1122, the buckling hooks contract due to an elastic restoring force thereof, causing the hook portions to be buckled to the positioning surfaces 1121, and at this time, the positioning surfaces 1121 of the protruding edges 112 are buckled to the buckling hooks in a direction for releasing the spring module, thereby locking the spring module in the compressed state. The spring modules in the compressed state are stacked and loaded into a packaging box 6 to facilitate transportation. The spring modules in the compressed state can be stacked in the vertical direction and then be put into the packaging box 6 having an elongated shape or can be stacked into the packaging box 6 in an arrangement, such as 1×10, 2×5, 4×5, for transportation. The spring modules that are packed into the packaging box 6 can be connected together through the connecting members 5, or the spring modules can be compressed to a locked state one by one and then put into the packaging box 6 for transportation.

[0047] The spring modules being maintained in the compressed state occupy less space, and more of the spring modules can be transported at one time, which is also convenient to relocate for the users and saves labor costs at this time.

[0048] When the spring module needs to be released for splicing, the spring module rotates to drive the buckling hooks to be separated from the positioning surfaces 1121 of the protruding edges 112 to reach the gaps 113, at this time, the spring module in the compressed state drives the spring module to be in a released state by a restoring force, and the spring modules can be then assembled into the elastic module for use by the user through the connecting members 5. The aforementioned rotation of the spring module means that the upper cover 2 and the base 1 rotate in opposite directions, thereby resulting in a relative movement.

[0049] In order to adjust a compression height of the spring module, the protruding cavity structure 111 comprises multiple layers of the protruding edges 112 that are discontinuous along the vertical direction, and each of the layers of the protruding edges 112 is disposed at a same position on a circumference of the protruding cavity structure 111. The buckling hooks are compressed to be buckled to different layers of the protruding edges 112, so that the compression height of the spring module can be adjusted.

EMBODIMENT 2

[0050] In the solution in Embodiment 1, as long as the base 1 and the upper cover 2 rotate relative to each other, the protruding edges 112 and the hook portions 212 will rotate relative to each other along a circumferential direction, causing the protruding edges 112 to be separated from the hook portions 212 for unlocking. Therefore, a locking structure of Embodiment 1 is not sufficiently stable and is prone to operational mistakes, resulting in the spring module being unlocked.

[0051] In order to enable a locked state to be more stable, referring to FIGS. 15-23, this embodiment differs from Embodiment 1 in that the protruding edges 112 of the second locking structure 11 in Embodiment 1 are discontinuous, while in Embodiment 2, a protruding edge 112 of the second locking structure is continuously arranged. A structure of the first locking structure 21 is the same as that of Embodiment 1 and will not be described herein. As the protruding edge 112 is continuously arranged, it is impossible to rotate the spring module to drive a relative movement of the protruding edges 112 and the hook portions 212 along the circumferential direction to separate the protruding edge 112 from the hook portions 212 for unlocking as in Embodiment 1. Therefore, even if the base 1 and the upper cover 2 rotate relative to each other, the spring module will not be released.

[0052] In order to achieve unlocking, in this embodiment, a closing plug 12 is disposed in a middle portion of the protruding cavity structure 111 of the base 1, when the closing plug 12 is installed in the base 1, the closing plug 12 can push the protruding edge 112 to extend outward along a radial direction, and after taking out the closing plug 12, the protruding edge 112 will contract in a direction towards a center of a circle, thereby causing the protruding edge 112 to be separated from the hook portions 212. In this way, in this embodiment, relative movement of the protruding edge 112 and the hook portions 212 in the circumferential direction in Embodiment 1 is changed to a relative movement in the radial direction. Eventually, the protruding edge 112 can be separated from the hook portions 212, thereby releasing the spring module.

EMBODIMENT 3

[0053] In the solution in Embodiment 1, as long as the base 1 and the upper cover 2 rotate relative to each other, the protruding edges 112 and the hook portions 212 will rotate relative to each other along a circumferential direction, causing the protruding edges 112 to be separated from the hook portions 212 for unlocking. Therefore, a locking structure of Embodiment 1 is not sufficiently stable, and operational mistakes are prone to happen, resulting in the spring module being unlocked. In the solution of Embodiment 2, as long as the closing plug 12 is taken out, the spring module will instantly release an elastic force, which is also prone to accidents.

[0054] In order to enable a locked state to be more stable, referring FIGS. 24-32, in this embodiment, a lower end surface of the upper cover 2 comprises a protruding cavity structure 213 having a cylindrical shape along a compression direction of the spring module, an inner wall of the protruding cavity structure 213 extends towards a center of the protruding cavity structure 213 to define protruding edges 214 as the first locking structure 21, and the protruding edges 214 are disposed at intervals; and

[0055] An upper end surface of the base 1 comprises buckling hooks corresponding to the protruding edges 214 one to one and at intervals and used as the second locking structure, the buckling hooks comprise connecting portions 114 and hook portions 115, and the hook portions 115 are disposed on outer sides of the connecting portions 114; and the hook portions 115 are gradually widened in a vertical downward direction to enable surfaces of the hook portions 115 facing the upper cover 2 to define first inclined surfaces 1151, surfaces of the hook portions 115 facing the base 1 define positioning surfaces 1152, and in order to cooperate with the inclined surfaces 1151 of the hook portions 115, lower surfaces of the protruding edges 214 define second inclined surfaces 2141.

[0056] In addition, an inner wall of the protruding cavity structure 213 comprises a first positioning wall 2131 and a second positioning wall 2132 respectively disposed on two sides of a protruding edge 214 along a circumferential direction, an upper end surface of the first positioning wall 2131 is lower than an upper end surface of the second positioning wall 2132, and a lower end surface of the first positioning wall 2131 is higher than a lower end surface of the second positioning wall 2132. The lower end surface of the second positioning wall 2132 extends to a lower end surface of the protruding cavity structure 213, and a spiral guiding inclined surface 2133 is connected to and disposed between the lower end surface of the first positioning wall 2131 and the lower end surface of the second positioning wall 2132.

[0057] When the spring module needs to be locked in a compressed state, the upper cover 2 and the base 1 are held by both hands to compress the spring module by a force, at this time, the protruding edges 214 on the upper cover 2 slide along the first inclined surfaces 1151 of the buckling hooks to be then buckled to the positioning surfaces 1152 of the hook portions 115, and the protruding edges 214 are buckled to the positioning surfaces 1152 of the hook portions 115 in a direction for releasing the spring module, thereby locking the spring module in the compressed state. The spring modules in the compressed state are then stacked and loaded into the packaging box 6 for facilitating transportation. At this time, since the two sides of the protruding edge 214 are respectively disposed with the first positioning wall 2131 and the second positioning wall 2132, the protruding edges 214 and the hook portions 115 cannot rotate relative to each other along the circumferential direction, thus ensuring stability of a locked state.

[0058] When the spring module needs to be released for splicing, the spring module needs to be firstly further compressed, so that the hook portions 115 move upward relative to the first positioning walls 2131, thereby releasing a buckled connection of the first positioning walls 2131 and the hook portions 115 along the circumferential direction. Since heights of the second positioning walls 2132 are relatively high, the second positioning walls 2132 still form a buckled connection with the hook portions 115 along the circumferential direction. In this way, the hook portions 115 can merely rotate in a direction facing the first positioning walls 2131. When the hook portions 115 rotate to pass over the first positioning walls 2131, the user can release a force for compressing the spring module, the spring module releases an elastic restoring force to enable the hook portions 115 to abut the spiral guiding inclined surfaces 2133, and the hook portions 115 will move along the spiral guiding inclined surfaces 2133, thereby releasing the spring module. This method can not only achieve stability of the locked state, but an elastic releasing process is also prolonged, thereby avoiding accidents caused by the elastic force of the elastic module being accumulated and released suddenly.

[0059] As in Embodiment 2, in this embodiment, the closing plug 12 is disposed in a middle portion of the buckling hooks of the base 1, the closing plug 12 is installed in the base 1 to push the buckling hooks to extend outward along a radial direction, after the closing plug 12 is taken out, the buckling hooks will contract towards a center of a circle, thereby causing the protruding edges 214 to be separated from the hook portions 115. In this way, in this embodiment, relative movement in the circumferential direction in Embodiment 1 is converted into relative movement of the protruding edges 214 and the hook portions 115 in the radial direction. Eventually, the protruding edges 214 are separated from the hook portions 115, thereby releasing the spring module. That is, in this embodiment, in addition to unlocking by compressing and rotating the spring module, unlocking can also be performed by taking out the closing plug 12.

EMBODIMENT 4

[0060] In the solution in Embodiment 1, as long as the base 1 and the upper cover 2 rotate relative to each other, the protruding edges 112 and the hook portions 212 will rotate relative to each other along a circumferential direction, causing the protruding edges 112 to be separated from the hook portions 212 for unlocking. Therefore, the locking structure of Embodiment 1 is not sufficiently stable, and operational mistakes are prone to happen, resulting in the spring module being unlocked.

[0061] In order to enable a locked state to be more stable, referring to FIGS. 33-41, in this embodiment, a lower end surface of the upper cover 2 comprises a first protruding cavity structure 215 having a cylindrical shape along a compression direction of a spring module, an end surface of the first protruding cavity structure 215 extends away from a center of the first protruding cavity structure 215 to define first protruding edges 216 as the first locking structure, and the first protruding edges 216 are disposed at intervals; and

[0062] An upper end surface of the base 1 comprises a second protruding cavity structure 13 having a cylindrical shape along the compression direction of the spring module, an upper end surface of the second protruding cavity structure 13 is a surface having an opening, and an inner wall of the surface having the opening extends towards a center of the second protruding cavity structure 13 to define second protruding edges 131 as the second locking structure. The second protruding edges 131 are disposed at intervals to form notches 132 between the second protruding edges 131 to enable the first protruding edges 216 to pass through.

[0063] Moreover, the first protruding edges 216 and the second protruding edges 131 comprise one or more positioning grooves 2161 and one or more positioning protrusions 1311 that are configured for a positioning cooperation.

[0064] When the spring module needs to be locked in a compressed state, the upper cover 2 and the base 1 are held by both hands to compress the spring module by a force, at this time, the first protruding edges 216 enter the second protruding cavity structure 13 through the notches 132, at this time, the base 1 and the upper cover 2 rotate to perform a relative rotation, the first protruding edges 216 and the second protruding edges 131 can rotate from a staggered state to an aligned state, so that the first protruding edges 216 and the second protruding edges 131 can be buckled together in a direction for releasing the spring module, thereby locking the spring module in the compressed state. The spring modules in the compressed state are then stacked and loaded into the packaging box 6 for facilitating transportation. Moreover, when the first protruding edges 216 and the second protruding edges 131 rotate to the aligned state, the one or more positioning protrusions 1311 enter the one or more positioning grooves 2161 to achieve positioning. In this way, the spring module is fixed in the locked state, and if a rotational force applied on the spring module is not large enough, the one or more positioning protrusions 1311 cannot be separated from the one or more positioning grooves 2161. Therefore, the locked state is more stable.

[0065] When the spring module needs to be released for splicing, a relatively large force is applied to drive the base 1 and the upper cover 2 to rotate relative to each other, and a squeezing force generated between the one or more positioning protrusions 1311 and the one or more positioning grooves 2161 will drive the first protruding edges 216 and the second protruding edges 131 to deform in a direction away from each other, thereby causing the one or more positioning protrusions 1311 to be separated from the one or more positioning grooves 2161. The base 1 and the upper cover 2 can then rotate freely, so that the first protruding edges 216 and the second protruding edges 131 are in the staggered state again, and the first protruding edges are removed from the notches 132 due to the elastic restoring force, thereby unlocking of the spring module.

EMBODIMENT 5

[0066] The unlocking of the spring module in Embodiments 3 and 4 requires two steps, that is, axial translation and circumferential rotation. Although these methods solve the problem of the locked state that is unstable in Embodiment 1, these methods also cause an operation for unlocking the spring module to be relatively complicated at the same time.

[0067] In order to simplify the operation for unlocking the spring module, this embodiment only adopts a method of the axial translation to unlock the spring module, and at the same time, a locked state can still be very stable. Referring to FIGS. 42-51, a lower end surface of the upper cover 2 comprises a protruding cavity structure 217 along a compression direction of the spring module, a top surface of the protruding cavity structure 217 is open, and an inner wall of the protruding cavity structure 217 forms a protruding edge 218 that is continuous as a first locking structure extending in a direction towards a center of the protruding cavity structure 217; an upper end surface of the base 1 comprises buckling hooks as the second locking structure 11, surfaces of the buckling hooks facing the base 1 define positioning surfaces 1153, the buckling hooks comprise connecting portions 114 and hook portions 115, the hook portions 115 are disposed on outer sides of the connecting portions 114, and the hook portions 115 are gradually widened along the vertical downward direction, so that surfaces of the hook portions 115 facing the upper cover 2 define inclined surfaces 1154.

[0068] Moreover, in this embodiment, two of the buckling hooks are provided, and opposite sides of the two of the buckling hooks respectively comprise a pulling rib 116 and a guiding groove 117; and an end of the pulling rib 116 is used as a fixed end to be fixedly connected to one of the two buckling hooks, and another end is used as a movable end to be disposed in the guiding groove 117. The guiding groove 117 comprises an initial position 1171, a first guiding surface 1172, a half-way position 1173, a second guiding surface 1174 and a third guiding surface 1175 arranged in sequence, and a distal end of the third guiding surface 1175 is in communication with the initial position 1171; an inner side of the guiding groove 117 comprises a one-way positioning surface 1176 disposed between the initial position 1171 and the third guiding surface 1175; and the one-way positioning surface 1176 is used to limit a moving direction of the pulling rib 116 to enable the pulling rib 116 to enter into the initial position 1171 from the third guiding surface 1175 instead of entering into the third guiding surface 1175 from the initial position 1171.

[0069] When the two of the buckling hooks are respectively not subjected to external forces, the pulling rib 116 is located in the initial position 1171.

[0070] When the spring module needs to be locked in a compressed state, the upper cover 2 and the base 1 are held by both hands to compress the spring module by a force, at this time, the protruding edge 218 on the upper cover 2 slides down along the inclined surfaces 1154 of the buckling hooks. During this process, the buckling hooks deform inwardly due to a squeezing force, causing the pulling rib 116 to move within the guiding groove 117. Moreover, due to an existence of the one-way positioning surface 1176, the pulling rib 116 can only enter the first guiding surface 1172 from the initial position 1171, move along the first guiding surface 1172, and finally fall into the half-way position 1173. The spring module is then continually pressed, the pulling rib 116 will then move along the second guiding surface 1174, when entering the third guiding surface 1175, the squeezing force between the inclined surfaces 1154 and the protruding edge 218 disappears, and the pulling rib 116 will move to the initial position 1171 along the third guiding surface 1175 due to a restoring force. At this time, the buckling hooks have also reset to initial positions, so that the protruding edge 218 is buckled to the positioning surfaces 1153 of the buckling hooks along a direction for releasing the spring module, thereby locking the spring module in the compressed state. The spring modules in the compressed state are then stacked and loaded into the packaging box 6 for facilitating transportation.

[0071] In this embodiment, the protruding cavity structure 217 forms a pushing portion 219 having a diameter that is smaller than that of the protruding edge 218 and located on an upper side of the protruding edge 218, when the spring module needs to be released, the spring module is pressed again, and the pushing portion 219 pushes the buckling hooks along the inclined surfaces to contract inward in a horizontal direction, causing the pulling rib 116 to repeat the aforementioned movement process again, and the buckling hooks are finally separated from the positioning surfaces 1153 to release the spring module.

[0072] It can be seen from the aforementioned process that whether the spring module is compressed or the spring module is released, the spring module only needs to be pressed, in this way, if a pressing force is canceled midway, the pulling rib 116 will be fixed at a current position in the guiding groove 117 instead of continuing to move, so that incorrect releasing of the entire spring module due to an operational mistake will not occur.

[0073] In this embodiment, the first guiding surface 1172 and the second guiding surface 1174 are inclined surfaces, the third guiding surface 1175 is a straight surface, a circular arc-shaped transition is disposed between the first guiding surface 1172 and the half-way position 1173, the one-way positioning surface 1176 is a protrusion located at a bottom of the initial position, and a bottom surface of the third guiding surface 1175 is an inclined surface. Therefore, the pulling rib 116 is blocked by the protrusion when moving from the initial position to the third guiding surface 1175, however, during a movement from the third guiding surface 1175 to the initial position 1171, as the bottom surface of the third guiding surface 1175 is the inclined surface, the pulling rib 116 will rise accordingly until entering into the initial position 1171 by passing over the protrusion during the movement.
