[0001] The disclosure relates to the sanitary field, in particular to a shower head lifting base.

Description of Related Art

[0002] A shower head lifting assembly generally includes a shower head lifting base and lifting rods. The lifting rods are clamped to notches of the shower head lifting base. As the pipe diameters of the lifting rods are different, the notches matched with the lifting rods also have to be different in size. In order to mount the lifting rods with different pipe diameters, in the prior art, a Chinese patent CN202909875U discloses a shower head lifting head which includes a sliding sleeve receptacle, a sliding sleeve body and an adjusting cover. A middle portion of the sliding sleeve body is provided with a notch for connecting the lifting rod in a sleeving manner, and the adjusting cover is connected to a screw of a movable buckle of the first sliding sleeve and can drive a movable buckle of a second sliding sleeve between the adjusting cover and the movable buckle of the first sliding sleeve to move inward, so as to fix the lifting head to the lifting rod. However, in the patent, for detachment, it is required to rotate the adjusting cover reversely till the adjusting cover is completelydetached from the screw on the movable buckle of the first sliding sleeve, and the adjusting cover is easy to lose, andinconvenience is caused to a user. Further, after the adjusting cover is detached, as the movable buckle of the second sliding sleeve and the adjusting cover are not directly connected, it is required to move the movable buckle of the second sliding sleeve outward or detach the movable buckle of the second sliding sleeve, the detaching process is cumbersome and the movable buckle of the second sliding cover is easy to lose, and for the subsequent installation, it is required to re-install the movable buckle of the second sliding sleeve and the adjusting cover, installation and detachment are thus quite inconvenient.

SUMMARY

[0003] The purpose of the disclosure is to overcome the above-mentioned defects or problems in the prior art by providing a shower head lifting base which is convenient to disassemble and assemble and is not easy to lose.

[0004] To accomplish the foregoing purposes, the following technical solutions are adopted by the disclosure.:

[0005] A shower head lifting base includes a body, a sliding part and a rotating part. An opening is formed in one end of the body, a notch for connecting a lifting rod in a sleeving manner is formed in a side wall of the body, a slideway is arranged in the body and runs through the opening and the notch, the sliding part is non-rotatably and slidably arranged in the slideway, and a first holding portion for holding the lifting rod is arranged at the end, facing the notch, of the sliding part, the rotating part and the sliding part are in screwed connection, and the rotating part is suitable for rotating relative to the body around a rotating shaft parallel to a sliding direction of the sliding part, and the rotating part and the body are in position-limiting connection along an extension direction of the rotating shaft, and the rotating part rotates to drive the first holding portion of the sliding part to get in and out of the notch along the slideway.

[0006] When the rotating part rotates, the rotating part does not move relative to the body, the sliding part thus is driven by the rotating part to slide along the slideway, such that the first holding portion gets in and out the notch and the first holding portion can tightly cooperate with the lifting rod inserted into the notch of the body, and therefore, the fixation of the lifting rods with different pipe diameters is realized. In a process of disassembling and assembling the shower head lifting base, it is only required to rotate the rotating part along different directions, the shower head lifting base is easy to operate and convenient to detach. Since the rotating part and the body are in position-limiting connection along the extension direction of the rotating shaft, the rotating part does not come off from the body in the rotating process, thus preventing losing of the rotating part.

[0007] Other features and advantages of the embodiments of the disclosure will be described in the following description and furthermore, some of the features and advantages are obvious from the description or are understood by implementing the embodiments of the disclosure. Other advantages of the embodiments of disclosure can be achieved and obtained by the schemes described in the description and accompanying drawings.

[0023] The sliding part 20 is provided with abutting surface facing the notch 112. A stopping wall abutting against the abutting surface is arranged between the abutting surface and the notch of the body 10, which can be implemented through the following structure:

[0024] After the sliding part 20 is inserted into the inner seat 12, the barbs 1234 form the stopping wall and the step surface 222 on the connecting wall 22 is the abutting surface. When the sliding part 20 moves toward the notch 112, when the sliding part 20 moves to a certain position, the abutting surface of the sliding part 20 abuts against the stopping wall, that is, the abutting surface abuts against the barbs 1234, and due to the cooperation between the stopping wall and the abutting surface, the situation that the sliding part 20 is coming off from the notch 112 in the sliding process since the screwed connection between the rotating part 30 and the sliding part 20 is disengaged or is going to disengage can be prevented. In addition, influence to slide of the sliding part 20 is further avoided, thus preventing increase of resistance during the sliding process of the sliding part 20.

[0025] A mounting process of the shower head lifting base of the embodiment is as follows:

[0026] The inner seat 12 is inserted into the housing 11 first as described above, and the body 10 mounted and the connecting seat 40 are fixedly connected, such that the inner seat 12, the housing 11 and the connecting seat 40 are fixedly connected, and the slot 32 of the rotating part 30 and the clamping block 1231 of the connecting portion 123 are in clamp connection. Then the sliding part 20 is non-rotatably and slidably arranged in the slideway as described above and is in screwed connectionto the rotating part 30.

[0027] It should be understood that the slot also can be formed in the inner wall of the inner seat 12 and the clamping block also can be arranged on the outer wall of the rotating part 30. In the embodiment, no further detailed description is made herein.

[0028] A using process of the shower head lifting base of the embodiment is as follows:

[0029] As shown in Fig. 7, when it is required to fix the lifting rod, the rotating part 30 is driven to rotate along a first direction, the first direction is a clockwise direction or an anticlockwise direction, and the rotating part 30 drives the sliding part 20 to move toward the notch, such that the first holding portion 21 of the sliding part 20 is located in the notch, and the first holding portion 21, the second holding portion 121 and the bridging portion 122 cooperate coordinately to fix the lifting rod. The protective cover 50 matched with the notch in shape can sleeve on the notch as needed, and the protective cover 50 can reduce friction to the lifting rod. Similarly, the cushion 121 of the second holding portion 121 can further reduce friction to the lifting rod.

[0030] As shown in Fig. 6, when it is required to loosen the lifting rod, the rotating part 30 is driven to rotate along a direction opposite to the first direction, and the rotating part 30 drives the sliding part 20 to move toward a direction away from the notch, such that the first holding portion 21 of the sliding part 20 gets outfrom the notch 112 gradually, and the first holding portion 21 no longer cooperate with the lifting rod tightly.

[0037] The connecting ring 612 and the inner seat 62 are in position-limiting connection along the axis direction of the connecting portion 623 as the third annular bump 6122 is hooked to the side wall, close to the bridging portion 622, of the annular groove 6232. The second annular bump 6121 of the connecting ring 612 forms the clamping block of the housing 61. The shell 611 is made from a rigid material generally, the inner seat 62 and the connecting ring 612 are made from plastics generally, and as the clamping block is formed on the inner wall of the housing 61 via the connecting ring 612, the preparation process of the shell 611 is simpler.

[0038] The guide structure (the inserting-connection bump 6214 and the inserting-connection slot 6113) between the inner seat 62 and the housing 61 makes the positioning of the inner seat 62 and the housing 61 be more accurate, and the installation is simpler.

[0039] The sliding part 20, the rotating part 30 and the connecting seat 40 are the same as those in embodiment I in structure.

[0040] During installation, the body 60 is mounted first as described above, that is, the inner seat 62 is inserted into the shell 611, then the connecting ring 612 is mounted, the body 60 mounted is fixedly connected to the connecting seat 40, and then the slot 32 of the rotating part 30 is in clamp connection to the clamping block formed by the second annular bump 6121 of the connecting ring 612. Then the avoidance opening 211 of the sliding part 20 is corresponding to the bridging portion 622, and the bridging portion 622 is inserted into the avoidance opening 211, and the guide bump 231 of the sliding part 20 is aligned with and inserted into the guide slot 6231, such that the sliding part 20 is non-rotatably and slidably arranged in the slideway and is threadedly connected to the rotating part 30.

[0041] As the shell 611 is made from the rigid material and the inner seat 62 is made from the plastic, when the rotating part 30 is in clamp connection to the connecting ring 612, since the connecting ring 612 is in threaded connection to the shell 611 and is in position-limiting connection to the connecting portion 623axially, when the rotating part 30 rotates, deformation of the shell 611 caused by external force is unlikely to happen, move of the connecting ring 612 caused by traction also is unlikely to happen, such that the gap between the shell 61 and the rotating part 30 shall not become bigger or smaller.

[0042] The using process of embodiment II is the same as that of embodiment I, which is not described in detail herein.

Embodiment III

[0043] The shower head lifting base of embodiment III is substantially the same as that of the embodiment I in structure, and as shown in Fig. 10 to Fig. 14, the difference between the shower head lifting base of embodiment III and that of the embodiment I lies in the rotating part. The shower head lifting base of embodiment III further includes the decorative cover. Description on the structure of the rotating part 70 and the decorative cover 80 of embodiment III is made below.

[0044] As shown in Fig. 10, the rotating part 70 includes a rotating seat 71 and a transmission wheel 72. As shown in Fig. 10 and Fig. 12, the rotating seat 71 is of a cylindrical structure, one end of the rotating seat 71 is provided with a screw 711 extending axially while the other end of the rotating seat 71 is provided with a positioning column 712 extending axially and several positioning bumps 713 uniformly distributed around the positioning column 712, slots 714 are circumferentially formed in an outer peripheral wall of a free end, close to the screw 711, of the rotating seat 71 and annular buckles 715 are arranged on the outer peripheral wall between the slots 714 and the positioning bumps 713.

[0045] The transmission wheel 72 is axially provided with a second positioning hole 722 and first positioning holes 721 uniformly formed in the peripheral edge of the second positioning hole 722, wherein the second positioning hole 722 is matched and in inserting connection with the positioning column 712, the first positioning holes 721 are matched and in inserting connection with the positioning bumps 713, such that the transmission wheel 72 is sleeved on the end, away from the screw 711, of the rotating seat 71, and the transmission wheel 72 is non-rotatably connected to the rotating seat 71. The outer peripheral wall of the transmission wheel 72 is provided with a ring of ratchets 721 joined successively, it should be understood that each ratchet 721 is formed by a ratchet back 7231 and a ratchet surface 7232, the ratchet surface 7232 of the ratchet 721 extends along the radial direction of the transmission wheel 72, and the ratchet back 7231 of the ratchet 721 is connected to the ratchet surface 7232 and inclines relative to the ratchet surface 7232. The transmission wheel 72 is made from plastics and has certain deformation capacity.

[0046] As shown in Fig. 10 and Fig. 11, the decorative cover 80 is of a cylindrical structure closed at one end, the inner side wall, close to the open end, of the decorative cover 80 is provided with an annular positioning slot 81 and the inner side wall is further circumferentially provided with several ribs 82 extending axially, each rib 82 is provided with an inclined surface 821 and a position-limiting surface 822, the position-limiting surface 822 extends along the radial direction of the inner side wall of the decorative cover 80 and the inclined surface 821 inclines relative to the position-limiting surface 822.

[0047] The mounting process is as follows:
The transmission wheel 72 is sleeved on the end, away from the screw 711, of the rotating seat 71 first, then the buckle 715 of the rotating seat 71 is aligned with and inserted into the positioning slot 81 of the decorative cover 80, such that the decorative cover 80 is in clampconnection to the rotating part 70, and the decorative cover 80 and the rotating part 70 are in position-limiting connection along the extension direction of the rotating shaft. At the moment, the ribs 82 of the decorative cover 80 are matched with the ratchets 723 of the transmission wheel 72. The inclined surfaces 821 of the ribs 82 abut against the ratchet backs 7231 of the ratchets 723 and the position-limiting surfaces 822 of the ribs 82 abut against the ratchet surfaces 7232 of the ratchets 723. The subsequent mounting steps are the same as those inembodiment I substantially, which is not described in detail herein.

[0048] As shown in Fig. 13, when it is required to fix the lifting rod, the decorative cover 80 is driven to rotate along the first direction. In Fig. 13, the first direction is the anticlockwise direction. The inclined surfaces 821 of the ribs 82 abut against the ratchet backs 7231 of the ratchets 723 to drive the rotating part 70 to rotate and further drive the sliding part 20 to move toward the notch, the first holding portion 21 of the sliding part 20 moves into the notch gradually, and when the first holding portion 21, the second holding portion 121 and the bridging portion 122 cooperatejointly to fix the lifting rod, the sliding part 20 is in position, that is the sliding part 20 can no longer move toward the notch. When the decorative cover 80 is further driven to rotate along the first direction, since the sliding part 20 cannot move forward continuously, the rotating resistance of the rotating part 70 is large. If it is needed to rotate the rotating part 70 continuously, larger rotating force is required. When the rotating force is larger, as the inner seat 12 is made from plastics, the inner seat 12 is easily to deform due to the traction force of the rotating part 70. In the embodiment, when the rotating force which drives the decorative cover 80 is large, the inclined surfaces 821 of the ribs 82 are separated from the ratchet backs 7231 of the ratchets 723, and the decorative cover 80 idles relative to the rotating part 70, that is the decorative cover 80 cannot drive the rotating part 70 to rotate, deformation of the inner seat 12 caused by the traction force thus is prevented.

[0049] When it is required to loosen the lifting rod, the decorative cover 80 is driven to rotate along the direction opposite to the first direction, the position-limiting surfaces 822 of the ribs 82 always abut against the ratchet surfaces 7232 of the ratchets 723, and relative rotation between the position-limiting surfaces 822 and the ratchet surfaces 7232 does not occur, the decorative cover 80 drives the rotating part 70 to rotate along the direction opposite to the first direction, the rotating part 70 drives the sliding part 20 to move toward the direction away from the notch, such that the first holding portion 21 of the sliding part 20 gets outof the notch 112 gradually, and the first holding portion 21 no longer cooperate with the lifting rod tightly.

[0050] As the inner seat 12 is made from plastics, when the rotating force of the decorative cover 80 is too large, the inner seat 12 is easily to deform due to the traction force. Through the scheme, when the rotating force of the decorative cover 80 is large, the ratchets 723 of the transmission wheel 72 deform, such that the decorative cover 80 idles relative to the rotating part 70, deformation of the inner seat 12 caused by the traction force thus is prevented.
