[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 As shown, this embodiment discloses a door lock, including as follows: Figures 2 to 6The diagram shows a sliding door handle and a lock body connected to the sliding door handle for unlocking and locking the door. The sliding door handle includes a handle assembly 1 and a keyhole 4 located within the handle assembly 1. A sliding cover assembly 2 is provided on the handle assembly 1. The sliding cover assembly 2 can slide relative to the handle assembly 1 to a blocked position. When the sliding cover assembly 2 is in the blocked position, it covers the keyhole 4. The sliding cover assembly 2 includes a fixing component 21 for engaging with the handle assembly 1 to fix the sliding cover assembly 2 when it slides to the blocked position. The handle assembly 1 is provided with an unlocking component 3, which pushes the fixing component 21 to disengage it from the handle assembly 1. With the structure of this utility model, the handle assembly is equipped with a sliding cover assembly, which can slide relative to the handle assembly. The fixing assembly is used to fix the sliding cover assembly relative to the handle assembly. The handle assembly is also equipped with an unlocking assembly, which can push the fixing assembly to disengage from the handle assembly. When the keyhole needs to be hidden, simply slide the sliding cover assembly to the blocking position to block the keyhole. At this time, the fixing assembly fixes the sliding cover assembly. When the keyhole needs to be exposed, press the unlocking assembly, which pushes the fixing assembly to disengage from the handle assembly. At this time, the sliding cover assembly can move relative to the handle assembly, exposing the keyhole. This structure can effectively hide the keyhole, protect the lock cylinder from foreign objects, make it smoother to use, and is more simple and beautiful.

[0025] As a specific implementation and not a limitation, to make the sliding cover assembly 2 slide more smoothly relative to the handle assembly 1, the handle assembly 1 includes a handle cover plate 12, on which guide rails 121 are symmetrically arranged. The sliding cover assembly 2 includes a sliding cover plate 23, on which slide rails 231 are symmetrically arranged. The slide rails 231 cooperate with the guide rails 121 to allow the sliding cover assembly 2 to move along the guide rails 121. The guide rails are linear guide rails, symmetrically arranged, and guide plates extending from the guide rails 121 can form a slide rail channel with the handle cover plate 12. The slide rails 231 can slide along the slide rail channel, making the sliding smoother. Optionally, lubricant can be applied to the guide rails 121 to reduce friction, and ball bearings can also be provided on the slide rails 231 or the guide rails 121 to reduce friction.

[0026] Furthermore, the sliding cover assembly 2 can slide relative to the handle assembly 1 to the open position. When the sliding cover assembly 2 is in the open position, the handle assembly 1 exposes the lock hole 4, and the fixing assembly 21 can cooperate with the handle assembly 1 to fix the sliding cover assembly 2 in the open position.

[0027] As a specific implementation and not a limitation, to ensure that the sliding cover assembly 2 does not wobble relative to the handle assembly 1 when the door handle is operated, two guide rails 124 are provided opposite to each other on the handle cover plate 12, forming a guide groove 125 between the two guide rails 124. A guide strip 233 is provided on the sliding cover plate 23, and the guide strip 233 cooperates with the guide groove 125 to limit the sliding cover assembly 2 to reciprocate along the length direction of the guide strip 233. Because the guide strip 233 is set on the guide groove 125 between the two guide rails 124, the sliding cover assembly 2 will strictly reciprocate along the length direction of the guide strip 233 when sliding, limiting the sliding cover assembly 2 from wobbling along the width direction of the guide strip 233.

[0028] Furthermore, to ensure the sliding cover assembly 2 is fixed after sliding into place, the sliding cover assembly 2 also includes a sliding cover 22. The handle cover plate 12 has a first limiting hole 122, and the sliding cover plate 23 has a first countersunk hole 232. The first countersunk hole 232 is used to install the fixing assembly 21. The fixing assembly 21 includes a fixing post 211 and a fixing spring 212. One end of the fixing spring 212 abuts against the fixing post 211, and the other end abuts against the sliding cover 22. The fixing post 211 is used to cooperate with the first limiting hole 122 for fixation. The handle cover plate 12 has a second limiting hole 123, which is used to cooperate with the fixing assembly 21 for fixation. The second limiting hole 123 is located between the two guide rails 121. When the sliding cover assembly 2 slides to the first limiting hole 122, the fixing spring 212 pushes out the fixing post 211 due to its elastic force and engages with the first limiting hole 122, fixing the sliding cover assembly 2 relative to the handle assembly 1. At this time, the sliding cover assembly 2 is in the blocking position, blocking the lock hole. When the sliding cover assembly 2 slides to the second limiting hole 123, the fixing spring 212 pushes out the fixing post 211 due to its elastic force and engages with the second limiting hole 123, fixing the sliding cover assembly 2 relative to the handle assembly 1. At this time, the sliding cover assembly 2 is in the open position, exposing the lock hole.

[0029] As a specific implementation and not a limitation, in order to enable quick unlocking after the sliding cover assembly 2 is fixed, the handle assembly 1 further includes a handle 11. The handle 11 is provided with a second countersunk hole 111 for installing the unlocking assembly 3. The unlocking assembly 3 includes a button 31 and a return spring 32. The button 31 includes an unlocking post 311. The return spring 32 is sleeved on the unlocking post 311. One end of the return spring 32 abuts against the handle cover plate 12, and the other end abuts against the button 31. The unlocking post 311 is aligned with the first limiting hole 122. The unlocking component 3 is set in the second countersunk hole 111 on the handle 11. The countersunk hole prevents the button 31 from falling off the handle 11. The button 31 is provided with an unlocking post 311, which is aligned with the first limiting hole 122. The return spring 32 is sleeved on the unlocking post 311. One end of the return spring 32 abuts against the sliding cover plate 12 and the other end abuts against the button 31. When the button 31 is pressed, the unlocking post 311 penetrates the first limiting hole 122 and pushes the fixing post 211, causing the fixing post 211 to disengage from the first limiting hole 122. At this time, the sliding cover component 2 can slide relative to the handle component 1.

[0030] Furthermore, to prevent the sliding cover assembly 2 from exceeding its limit during sliding, a limiting wall 2311 is provided at one end of the slide rail 231 away from the first countersunk hole 232. The limiting wall 2311 cooperates with the guide rail 121 to restrict the sliding cover assembly 2 from moving towards the locking hole 4. A limiting boss 1232 is provided on the second limiting hole 123. The side wall of the limiting boss 1232 cooperates with the side wall of the fixing post 211 to restrict the sliding cover assembly 2 from moving away from the locking hole 4 when it slides to the second limiting hole 123. This prevents the sliding cover assembly 2 from exceeding its limit and ensures that it moves back and forth between the limiting wall 2311 and the limiting boss 1232.

[0031] Furthermore, to ensure that when the fixing post 211 is fixed in the second limiting hole 123, pushing the sliding cover assembly 2 allows the fixing post 211 to easily disengage from the second limiting hole 123, the wall of the second limiting hole 123 is provided with a chamfer 1231. The chamfer 1231 is a curved chamfer, and when the sliding cover assembly 2 is pushed, the fixing post 211 can move along the curved surface of the chamfer 1231, allowing the fixing post 211 to disengage from the second limiting hole 123.

[0032] As a specific implementation and not a limitation, to facilitate the disassembly and installation of the sliding cover assembly 2, the handle 11 is provided with a disassembly hole 112, which is aligned with the second limiting hole 123. When the sliding cover assembly 2 needs to be disassembled, it needs to be slid until the fixing post 211 is placed on the second limiting hole 123. At this time, a cylindrical object needs to be taken from the outside, penetrate the disassembly hole 112, and abut against the fixing post 211. Push the cylindrical object so that the fixing post 211 moves upward and passes the highest point of the limiting boss 1232. At this time, the sliding cover assembly 2 can be detached from the handle assembly 1. When the sliding cover assembly 2 needs to be installed, the side of the limiting boss 1232 away from the second limiting hole 123 is set with an inclined surface. After the slide rail 231 is aligned with the guide rail 121, the sliding cover assembly 2 is slid so that the fixing post 211 slides through the inclined surface and passes the limiting boss 1323 to achieve installation.

[0033] The specific working principle of this embodiment is as follows:

[0034] When the keyhole needs to be hidden, the sliding cover assembly is used to fix the fixing post in conjunction with the first limiting hole. At this time, the sliding cover assembly covers the keyhole. When the keyhole needs to be exposed, simply press the button on the handle assembly to make the unlocking post abut against the fixing post, and the fixing post disengages from the second limiting hole. At this time, the sliding cover assembly can expose the keyhole.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
