The invention discloses a back locking mechanism for a door lock, which comprises a rotating power shaft, a locking piece (3) and a stirring piece (1), wherein the rotating power shaft is mounted on a lock case bottom plate in a rotation manner; the locking piece (3) is in linkage connection with the rotating power shaft, and comprises a retracting locking contact point (3a) and an extending locking contact point (3b); the retracting locking contact point (3a) is matched with a locking structure on a lock tongue plate (2) for preventing the lock tongue plate (2) from locking out; the extending locking contact point (3b) is matched with the locking structure on the lock tongue plate (2) for preventing the lock tongue plate (2) from locking in; the stirring piece (1) is arranged on the rotating power shaft and drives the lock tongue plate (2) associatively; in a locking-in back locking state, a relative delay rotating mechanism is arranged between the stirring piece (1) and the locking piece (3); in a locking-out state, a locking piece back locking returning mechanism is arranged between the locking piece (3) and the stirring piece (1); the retracting and extending, and back locking of the lock tongue plate can be realized directly through the handle of the door lock.
Description
technical field [0001] The invention relates to a door lock anti-lock mechanism, in particular to a door lock anti-lock mechanism controlled by a handle of the door lock. Background technique [0002] A door lock is a commonly used door protection device to prevent illegal intrusion, usually including a lock housing; a lock that is arranged in the lock housing and is limited to reciprocating sliding between the lock-out terminal position and the lock-in terminal position along the lock-out direction A tongue assembly, and a lock-in and lock-out control mechanism that controls the reciprocating sliding of the lock tongue assembly. Wherein the deadbolt assembly has a deadbolt plate for supporting the deadbolt. With the continuous improvement of protection requirements and the increase of door lock functions, the internal structure of door locks is also becoming more and more complex. Cause more and more crowding in the door lock lock housing thus, also make the volume of doo...
