Self-bouncing trigger lock body mechanism and lock

Abstract

The invention provides a self-bouncing trigger lock body mechanism and a lock, and belongs to the technical field of locks. The self-bouncing trigger lock body mechanism comprises a lock body, a mainbolt, a first locking piece, a second locking piece, a latch bolt and a trigger bolt; the main bolt is provided with a first position extending out of the lock body and a second position retracting into the lock body; the latch bolt is provided with a third position extending out of the lock body and a fourth position retracting into the lock body, and the latch bolt is used for releasing lockingof the first locking piece to the main bolt located at the second position in the process that the latch bolt extends out of the fourth position to the third position; and the trigger bolt is providedwith a fifth position extending out of the lock body and a sixth position retracting into the lock body, and the trigger bolt is used for releasing locking of the second locking piece to the main bolt at the second position in the process that the trigger bolt retracts from the fifth position to the sixth position. When a door is closed, the main bolt can be triggered to extend out only by releasing the latch bolt after the latch bolt is pressed in, and it is guaranteed that the main bolt extends out only when the door is closed in place, so that the main bolt is prevented from impacting a door frame in the door closing process, and the service life of the lock is effectively prolonged.

Description

technical field [0001] The present application relates to the technical field of locks, in particular to a self-spring trigger lock body mechanism. Background technique [0002] In the existing door lock, the main bolt is linked with the oblique bolt. After the door is opened, the oblique bolt protrudes from the lock body, and the main bolt retracts to the lock body; when the door is closed, the main bolt returns under the action of the door frame. At the same time, the main deadbolt protrudes outwards. If the door is not closed properly, the main deadbolt stretches out, and the main deadbolt hits the door frame, which reduces the service life of the door lock. Contents of the invention [0003] The embodiment of the present application provides a self-bounce trigger lock body mechanism to solve the problem that the service life of the door lock is reduced due to the main bolt protruding out before the door is fully closed. [0004] In the first aspect, the embodiment of ...
