As shown in fig. 1 and 2, the present embodiment provides a lock, which includes: lock core 20, lock shell 10, handle structure and elastomeric damper 40. Wherein, the lock core 20 is arranged on the lock shell 10; the handle structure is connected with the lock cylinder 20 and is used for driving the lock cylinder 20 to move relative to the lock shell 10; the lock housing 10 has a stop face between which at least part of the resilient buffer 40 is located and the handling structure.

For convenience of description, the position of the lock core 20 when the lock is in the unlocked state is referred to as the home position, and the handle structure is closest to the stop surface when the lock is in the unlocked state.

At the in-process of locking, handle structure drives lock core 20 and removes relatively lock shell 10 to make lock core 20 stretch out lock shell 10, play the locking effect. At the time of unlocking, the lock cylinder 20 moves in a direction opposite to the moving direction during locking to return to the original position; because the handle structure links to each other with lock core 20, therefore handle structure and lock core 20 synchronous movement, handle structure moves to the direction that is close to the backstop face. Because elastic buffer member 40 is located between backstop face and the handle structure at least partial structure, consequently before handle structure and backstop face contact, handle structure earlier with elastic buffer member 40 contact, elastic buffer member 40 plays the cushioning effect to handle structure, can absorb the impact force to all playing the guard action to backstop face and handle structure, alleviate or even absorb the impact between handle structure and the backstop face completely.

In a feasible implementation, after the unlocking, the lock is switched from the locking state to the unlocking state, the handle structure is shifted by the user, and the handle structure drives the lock cylinder 20 to move so as to drive the lock cylinder 20 to move to the initial position.

Alternatively, as shown in fig. 6, in a preferred embodiment, the lock further includes a reset structure 60, and the reset structure 60 is mounted on the lock case 10 for moving the lock cylinder 20 to the initial position. So set up, after the unblock, drive lock core 20 by reset structure 60 and remove, lock core 20 drives handle structure and removes, finally makes lock core 20 get back to initial position for handle structure removes by the backstop face.

In a possible embodiment, the return structure 60 comprises elastic return elements respectively associated with the lock cylinder 20 and with the lock case 10. When the lock core 20 is driven by the handle structure to move from the initial position to the locking position, the elastic reset piece stores force, and when the lockset is in the locking state, the elastic reset piece is always in the force storage state. After the tool to lock unblock, elasticity resets and restores to the original condition gradually, and at this in-process, elasticity resets and drives lock core 20 and remove to initial position, lock core 20 and handle structure are connected to drive handle structure and remove to the direction that is close to the backstop face. The reset structure 60 has a simple structure, occupies a relatively small space, and does not need to be electrified.

The elastic return member may be a spring, preferably a clockwork spring or an extension spring, the spring preferably being made of metal.

With continued reference to fig. 6, in a preferred embodiment, the lock case 10 is provided with a sliding slot 11, the lock cylinder 20 is located in the sliding slot 11, a side wall of the sliding slot 11 is provided with a first opening, the handling structure is connected with the lock cylinder 20 at the first opening, and the handling structure moves within the opening. So set up, lock core 20 removes along the moving direction of spout 11, and in the removal process of lock core 20, spout 11 plays spacing guide's effect to lock core 20.

The sliding grooves 11 may be formed by being recessed downward at one side of the lock case 10, or the sliding grooves 11 may be formed by providing partition plates at one side of the lock case 10, and the areas enclosed between the partition plates form the sliding grooves 11. When the sliding groove 11 is surrounded by a partition, the side wall of the first opening can serve as a stop surface, or, preferably, a stop portion 12 is provided on the lock case 10 in the area next to the first opening, and the side of the stop portion 12 facing the handle structure is the stop surface.
