Latch bolt self-locking module structure of full-automatic lock body

Abstract

The invention discloses a latch bolt self-locking module structure of a full-automatic lock body. The latch bolt self-locking module structure is characterized in that the latch bolt self-locking module structure comprises a latch bolt self-locking module and a trigger bolt assembly which are arranged in a lock shell; the latch bolt self-locking module comprises a latch bolt head, a latch bolt shell, an unlocking shifting piece, reset compression springs, self-locking push rods and reset seats, and is characterized in that the reset seats corresponding to the self-locking contact blocks are arranged in the latch bolt shell, the self-locking push rods extend out of the reset seats and are positioned in guide grooves of the latch bolt box, and the reset compression springs are arranged at the set positions of the sides of the self-locking push rods. And then the unlocking shifting piece is arranged on the latch bolt box and is combined with the tail part of the self-locking push rod and then is locked by the cover plate, and the latch bolt head is arranged in the latch bolt shell jack to form the latch bolt self-locking module. The latch bolt is compact and simple in structure, the latch bolt can easily shift the self-locking push rod to unlock when the latch bolt corresponding to a door frame lock hole is subjected to door deformation and large external pressure, and the latch bolt belongs to an innovative leading technology at home and abroad.

Description

technical field [0001] The invention relates to the field of intelligent locks, more specifically, it relates to a self-locking module structure of an oblique tongue of a fully automatic lock body. Background technique [0002] At present, there are many functions of smart locks on the market. Its function is that the mechanical function of unlocking is replaced by smart unlocking. It is different from traditional mechanical locks and has safety and convenience. However, people often forget to bring the key when they go out and bring the door back to lock it, causing trouble. . In order to solve this problem, some door locks design complex structures to realize the self-locking function of the oblique tongue, but during self-locking, it is still necessary to insert a key into the lock cylinder to realize releasing the self-locking. Therefore, there has been technical research, such as patent No. 201920564611.7, titled "Latch bolt self-locking structure of door lock", which ...
