TECHNICAL FIELD
BACKGROUND
[0002] In various product applications, a door lock is a critical part. A structure, an appearance, and a material of the door lock vary based on different application scenarios. An ordinary door lock usually has a lock cylinder made of a metal material, and the lock cylinder is fastened to a panel of a box body in a threaded connection manner. After an external key is manually rotated, the lock cylinder compresses a spring and then the lock is opened. After the key is released, the lock cylinder may be reset, and the panel restores to a closed state. Based on an anti-theft characteristic and operation convenience of the door lock, the lock usually has a relatively complex structure and relatively high costs. For another door lock, a lock cylinder is driven to rotate through rotation of a key, and a barrier plate of the lock cylinder is detached from a fixing point, thereby achieving an unlocking function. Rotation of the lock cylinder needs to be driven by using the key, and the lock cylinder cannot automatically rebound.

DESCRIPTION OF EMBODIMENTS
[0017] To make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
[0018] FIG. 1 to FIG. 3 show an apparatus having a door lock assembly according to an embodiment of the present invention. FIG. 1 is a three-dimensional diagram of the apparatus, FIG. 2 is a front view of the apparatus, and FIG. 3 is a left view of the apparatus. The apparatus may be a communications device such as an access terminal box, or may be an accommodating box, an office cabinet, a safe, or the like. Examples are not listed one by one. The apparatus includes a first panel 1 and a second panel 2. If the apparatus is an apparatus having a lateral opening, the first panel 1 may be a door frame or a cabinet body, and the second panel 2 is a door plate. If the apparatus is a container having a top opening, the first panel 1 may alternatively be a side frame of the container, and the second panel 2 is a lid. The foregoing is merely an example for description and is not used as a specific limitation. Certainly, the first panel 1 and the second panel 2 may alternatively be interchanged. The first panel 1 is a door plate or a lid, and the second panel 2 may be a door frame, a cabinet body, or a side frame. The first panel 1 and the second panel 2 used in this embodiment are merely for ease of description. It is emphasized that a part of the door lock assembly is installed on the first panel 1, and another part of the door lock assembly 3 is installed on the second panel 2. The first panel 1 and the second panel 2 are locked with and separated from each other by using the door lock assembly 3. In another embodiment, the first panel 1 and the second panel 2 may alternatively be merely fixing points at which the door lock assembly 3 is fastened. In each of FIG. 1 to FIG. 3, an example in which two door lock assemblies 3 are disposed on the apparatus is used. This is not a restrictive description of an implementation, and a specific quantity is set based on an actual case.
[0020] As shown in FIG. 3 to FIG. 7, the door lock assembly 3 includes a clamping portion 32 fastened to the first panel 1 and a lock cylinder 31 fastened to the second panel 2. As shown in FIG. 6 and FIG. 7, the lock cylinder 31 includes a shaft body 310 and a guiding head 311 disposed at an end of the shaft body 310, and a joint of the guiding head 311 and the shaft body 310 is provided with a first concave portion 312. Preferably, in this embodiment, the guiding head 311 is one of a frustum, a pyramid, and a cone. In FIG. 6 and FIG. 7, the pyramid is used as an example for description. A quantity of guiding bevels of the pyramid is preferentially set to an even number. An objective of symmetrically disposing an even quantity of guiding bevels is to lock the lock cylinder 31 with the clamping portion 32 by inserting the lock cylinder 31 into the clamping portion 32 through guiding of the guiding head 311 in a relatively easy manner.
[0021] As shown in FIG. 8 and FIG. 9, the clamping portion 32 includes a base 321 and a clamp 322. The base 321 is provided with a first through hole 3210 for the shaft body 310 and the guiding head 311 to pass through. The clamp 322 is configured to clamp the first concave portion 312 on the lock cylinder 31. The guiding head 311 and the shaft body 310 pass through the first through hole 3210 on the base 321 of the clamping portion 32 to be locked with the clamp 322, so that the first panel 1 is locked with the second panel 2. The guiding head 311 and the shaft body 310 are detached from the clamp 322 with an external force, so that the first panel 1 is detached from the second panel 2. In this embodiment, the clamp 322 further includes a first elastic arm 3221 and a second elastic arm 3222. The first elastic arm 3221 and the second elastic arm 3222 are fastened to a same side surface of the base 321 in an arc manner. Preferably, the first elastic arm 3221 and the second elastic arm 3222 are symmetrically disposed. A gap having a preset width is formed between tail ends of the first elastic arm 3221 and the second elastic arm 3222. To facilitate alignment between the lock cylinder 31 and the clamp 322 to enable the lock cylinder 31 to be successfully inserted into the lock cylinder 322, the gap between the first elastic arm 3221 and the second elastic arm 3222 and the first through hole 3210 are located in a same plane.
[0022] As shown in FIG. 6 and FIG. 7, the first concave portion 312 further includes a first inclined surface 3120 and a second inclined surface 3121. The first inclined surface 3120, the second inclined surface 3121, and the guiding head 311 facilitate formation of the first concave portion 312. Preferably, the first inclined surface 3120 and the second inclined surface 3121 are symmetrically disposed.
[0023] When the guiding head 311 of the lock cylinder 31 is inserted into the clamp 322, the guiding head 311 enables the first elastic arm 3221 and the second elastic arm 3222 to elastically extend outward. When the guiding head 311 exceeds the gap, the first elastic arm 3221 and the second elastic arm 3222 restore elasticity and clamp the first concave portion, that is, clamp the first inclined surface 3120 and the second inclined surface 3121. Mutual combination between the guiding head 311 and the open-type first elastic arm 3221 and second elastic arm 3222 forms a torque when a door is closed. Therefore, automatic locking between the first panel 1 and the second panel 2 can be implemented without turning a key. When the lock cylinder 31 is detached from the clamp 322, when the lock cylinder 31 rotates by a specific angle, because parts, other than the first inclined surface 3120 and the second inclined surface 3121, of the guiding head 311 and the shaft body 310 are not disposed in a concave manner, it is quite easy to smoothly detach the lock cylinder 31 from the first elastic arm 3221 and second elastic arm 3222 with a little external force during detaching.
[0024] As shown in FIG. 4, FIG. 5, and FIG. 8, the second panel 2 is provided with a second concave portion 10 for accommodating the lock cylinder 31 and a second through hole 11 for the lock cylinder 31 to pass through. The second concave portion 10 is provided with a limiting groove 100 configured to limit a rotating angle of the lock cylinder 31. The shaft body 310 of the lock cylinder 31 is provided with at least one limiting block 313 corresponding to the limiting groove 100, and the limiting block 313 may be a protrusion. When the lock cylinder 31 rotates in the second concave portion 10, the limiting block 313 rotates in the limiting groove 100. The lock cylinder 31 and the second panel 2 limit an unlocking angle by using the limiting block 313 and the limiting groove 100. The shaft body 310 of the lock cylinder 31 is further provided with a supporting surface 314 corresponding to the second concave portion 10. Preferably, the supporting surface 314 is perpendicularly fastened to the shaft body 310. It should be noted that, the supporting surface 314 and the shaft body 310 may be integrally formed or may be implemented in another manner.
[0025] Further, in another embodiment, the door lock assembly 3 further includes a clip spring 33 configured to fasten the lock cylinder 31 and the second panel 2. A length or a diameter of the clip spring 33 is preferably greater than a diameter of the second through hole 11. In this way, the lock cylinder 31 is not detached from the second panel 2 when the clip spring 33 is clipped to the lock cylinder 31. The shaft body 310 of the lock cylinder 31 is provided with a third concave portion 315 corresponding to the clip spring 33. When the lock cylinder 31 is placed in the second concave portion 10, the lock cylinder 31 is fastened to the second panel 2 by clipping the clip spring 33 to the third concave portion 315. An elastic characteristic of the clip spring 33 not only plays a role of fastening the lock cylinder 31 to the second panel 2, but also keeps a function that the lock cylinder 31 can freely rotate in the second concave portion 10.
[0026] As shown in FIG. 9 and FIG. 10, an external surface of the supporting surface 314 is provided with an unlocking portion 316 having a preset shape, and the unlocking portion 316 is shown in figures by using a common triangle. Preferably, to beautify design, a sum of thicknesses of the supporting surface 314 and the unlocking portion 316 is not greater than a depth of the second concave portion, so that the top of the unlocking portion 316 is not higher than the second panel 2. In this embodiment, a key with a groove in same preset shape may be used to turn the unlocking portion 316 to drive the lock cylinder to rotate, so that the first panel 1 is detached from the second panel 2.
[0027] In the door lock assembly disclosed in the embodiments of the present invention, the lock cylinder 31 is locked with the clamping portion 32 by inserting the lock cylinder 31 into the clamping portion 32 through guiding of the guiding head 311. During detaching, the guiding head 311 and the shaft body 310 can be detached from the clamp 322 with a little external force, so that the first panel 1 is detached from the second panel 2. The door lock assembly has few parts, low costs, and strong practicality, and it is simple to assemble the door lock assembly.
