Abstract
Description
Technical Field
[0001] The utility model relates to the field of locks, in particular to a slidable lock core protection structure. Background Art
[0002] When the key is needed to manually unlock the lock, the cover plate of the locking connection is removed and the lock is manually unlocked. However, the locking connection between the cover plate and the lock body usually requires a tool to open normally. Therefore, it is extremely inconvenient to manually unlock the mechanical lock cylinder of the current electronic lock by using a key. Utility Model Content
[0003] The purpose of the utility model is to facilitate manual unlocking between a key and a mechanical lock cylinder by slidingly connecting the inner lock cylinder handle and the lower lock cylinder handle.
[0004] The technical solution adopted by the present utility model is: a slidable lock core protection structure, including a lock core handle, a lock core handle and a lock core handle bottom, the lock core handle is connected to the lock core handle, a groove is provided in the lock core handle, and two side walls of the groove are relatively provided with raised connecting structures, a sliding platform is provided on one side of the lock core handle bottom, and sliding grooves are relatively provided on both sides of the sliding platform, the sliding platform is arranged in the groove, and the connecting structures on both sides are arranged in the sliding grooves on both sides, and the lock core handle is driven to slide up and down on the surface under the lock core handle by pulling the lock core handle.
[0005] Furthermore, a limiting groove is provided in the lock core handle, and a limiting screw is provided under the lock core handle. The end of the limiting screw protrudes from the surface under the lock core handle. When the sliding platform is provided in the groove, the protruding end of the limiting screw is provided in the limiting groove.
[0006] Furthermore, arc-shaped positioning structures are provided at both ends of the lock core handle, and a positioning hole is provided under the lock core handle. A spring and a positioning bead are provided in the positioning hole. One end of the spring abuts against the bottom of the lock core handle, and the other end abuts against the positioning bead. One side of the positioning bead protrudes from the surface under the lock core handle, and the spring can push the positioning bead to be arranged in the arc-shaped positioning structure.
[0007] Furthermore, one side of the lock core handle is arranged on the surface of the lock core handle and is screwed together by a screw.
[0008] Furthermore, a display plate is provided on the upper surface of the lock cylinder handle.
[0009] The advantageous effect of the present invention compared with the prior art is that when it is necessary to insert the key into the lock cylinder to unlock it, the lock cylinder handle is first pulled to drive the lock cylinder handle to slide so as to expose the key entry hole, and the key is then inserted into the lock body to unlock it. When unlocking is completed, the lock cylinder handle is moved to drive the lock cylinder handle to cover the surface under the lock cylinder handle, thereby shielding the key entry hole and playing a protective role to prevent foreign objects from entering the lock hole and making it impossible to unlock the lock. The operation of manually unlocking with a key is simpler and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] like Figures 1 to 7The present invention relates to a slidable lock core protection structure, comprising a lock core handle 10, a lock core handle 20 and a lock core handle lower 30. One side of the lock core handle 30 is arranged on the surface of the lock core handle 20 and is screwed together by a screw 31. A groove 21 is provided on one side of the lock core handle 20, and raised connecting structures 22 are provided on both side walls of the groove 21. A sliding platform 32 is provided on one side of the lock core handle lower 30, and sliding grooves 33 are provided on both sides of the sliding platform 32. The sliding platform 32 is arranged in the groove 21, and the connecting structures 22 on both sides are arranged in the sliding grooves 33 on both sides. By pulling the lock core handle 10, the lock core handle 20 is driven to slide up and down on the surface of the lock core handle lower 30.
[0019] When in use, the lock cylinder handle 30 is fixedly installed with the lock body, and a key entry hole 34 is provided in the lock cylinder handle 30. When it is necessary to insert the key into the lock cylinder to unlock it, first pull the lock cylinder handle 10 to drive the lock cylinder handle 20 to slide to expose the key entry hole 34, and then insert the key into the lock body to unlock it. When unlocking is completed, move the lock cylinder handle 10 to drive the lock cylinder handle 20 to cover the surface of the lock cylinder handle 30, thereby blocking the key entry hole 34 to play a protective role and prevent foreign objects from entering the lock hole and making it impossible to unlock.
[0020] The lock core handle 20 is provided with a limiting slide groove 23, and the lock core handle 30 is provided with a limiting screw 35. The end of the limiting screw 35 protrudes from the surface of the lock core handle 30. When the sliding platform 32 is set in the groove 21, the protruding end of the limiting screw 35 is set in the limiting slide groove 23. When the lock core handle 20 slides up and down on the surface of the lock core handle 30, the limiting screw 35 in the limiting slide groove 23 can prevent the lock core handle 20 from separating from the lock core handle 30 and play a limiting role.
[0021] Both ends of the lock core handle 20 are provided with an arc-shaped positioning structure 24, and the lock core handle bottom 30 is provided with a positioning hole 36, and a spring 37 and a positioning bead 38 are provided in the positioning hole 36. One end of the spring 37 abuts against the lock core handle bottom 30, and the other end abuts against the positioning bead 38. One side of the positioning bead 38 protrudes from the surface of the lock core handle bottom 30, and the spring 37 can push the positioning bead 38 to be set in the arc-shaped positioning structure 24.
[0022] During specific implementation, when it is necessary to expose the key entry hole 34 under the lock cylinder handle 30 for unlocking, the movable lock cylinder handle 20 slides on the surface of the lock cylinder handle 30, and when it moves to the corresponding position, the positioning bead 38 will be pushed by the spring 37 to fall into the arc-shaped positioning structure 24 at the top of the lock cylinder handle 20, and the lock can be unlocked by the key. When the lock cylinder handle 20 needs to cover the surface of the lock cylinder handle 30 under the lock cylinder handle for protection, the lock cylinder handle 20 slides on the surface of the lock cylinder handle 30 under the lock cylinder handle, and when it moves to the corresponding position, the positioning bead 38 will be pushed by the spring 37 to fall into the arc-shaped positioning structure 24 at the bottom of the lock cylinder handle 20 to complete positioning. At this time, the lock cylinder handle 20 can protect the lock cylinder handle 30.
[0023] A display plate 11 is provided on the surface of the lock cylinder handle 10 . The display plate 11 can be provided with a movable mark to remind the user to pull the lock cylinder handle 10 so that it can slide up and down for easy operation.
