Abstract

The invention discloses a low-noise mechanism and a lock with the same. The low-noise mechanism comprises a rack (1). One end, in the length direction, of the rack (1) is mounted on a spring bolt component (10); the rack (1) is meshed with a transmission gear (6); an energy-storage flywheel (7) is fixedly arranged on and is coaxial with the transmission gear (6). The lock with the low-noise mechanism comprises a lock shell, the spring bolt component (10), a driving component and the low-noise mechanism. The lock shell is provided with a faceplate. A spring bolt hole is formed in the faceplate. The spring bolt component (10) comprises a spring bolt and a guide plate fixedly connected with the spring bolt. The driving component is used for driving the spring bolt component (10) to extend or retract. By the low-noise mechanism, the technical problem that noises are generated due to the fact that abnormal sounds are caused during collision between the spring bolt and a pin hole of a door fame when the spring bolt extends in the prior art is solved.

Description

technical field

[0001] The invention relates to a lock, in particular to a low-noise mechanism for the lock and the lock with the mechanism. Background technique

[0002] The lockset in the prior art mainly includes components such as a lock body, a secondary lock body, a dead bolt and a mechanical transmission mechanism. When locking the door, under the action of the mechanical transmission mechanism, the lock tongue quickly passes through the lock body and inserts into the auxiliary lock body, so as to achieve the purpose of locking. It has a strong impact force, causing the deadbolt to collide when inserted into the pin hole in the door frame, making noise.

[0003] In order to avoid the generation of noise, a damping device is provided in the lock in the prior art, such as the end where the dead bolt contacts the pin hole in the door frame is covered with a flexible non-metallic material, but due to the nature of the dead bolt and the non-metallic material Different, u...
