Description
Technical Field

Background
The lock is an article which people cannot leave in daily life, and people always use the lock to store the article from old times so as not to be stolen by others. The bolt of some existing locks generally completes the door closing and opening operations through the telescopic action of a spring. In such a configuration, the release of the locking mechanism to the bolt can be automated at least in one direction of movement of the lock-out or lock-in. However, due to the biasing force of the spring, the lock tongue is always in an acceleration state after being released, so that when the lock tongue moves to a movement end point and meets a limiting part, violent collision can be generated, and if the lock tongue collides the inner side surface of a lock shell panel to make a loud sound when a door is opened and closed. Therefore, due to the structural design, the lockset can make a loud sound in the application process to influence the surrounding environment and further influence the rest of people, and the lockset cannot be durable.
Therefore, in order to solve the problem that the lock generates noise during unlocking and locking, chinese patent document CN103899145B discloses a silent lock body with damping, which mainly comprises: a damper is arranged between the lock bolt and the lock body and plays a role in damping and buffering, so that the lock bolt slowly advances until the lock bolt is in place when the lock is unlocked and locked. Therefore, the problem that the spring quickly resets the bolt to cause the bolt to quickly impact the lock body and other parts to generate noise in the prior art is avoided. In addition, the patent document also discloses that the damper is a linear radial damper, the bolt has no resistance when retracting to the bottom box assembly, and the bolt slowly returns under the action of the damping force when returning to the start-stop position. It is clear that chinese patent document CN103899145B discloses a non-complete solution, in which the function of the damper is not implemented to the extent that those skilled in the art can implement, that is, the "slow-out and fast-in function" is still a long-desired desire.
