Labor-saving touch trigger lock mechanism

Abstract

The invention relates to a labor-saving touch trigger lock mechanism. The labor-saving touch trigger lock mechanism comprises a lock shell, a lock mounting plate, a lock tongue linkage assembly and a lock tongue tough trigger assembly, a guide rod of the lock shell is sleeved with a driven gear with an eccentric shaft hole, the front end of the lock tongue linkage assembly is fixedly provided with a center guide column and side guide columns, a touch trigger rod of the lock tongue touch trigger assembly right faces a releasing check block in the lock shell, and a convex shoulder of the releasing check block can triggered by the touch trigger rod to release or restrain moving. Locking and unlocking can be achieved. The mechanism is simple in structure, assembling is easy, and work is reliable.

Description

technical field [0001] The invention relates to the technical field of lock bodies, in particular to a labor-saving touch latch mechanism. Background technique [0002] With the development of society, residents' income and living standards have been continuously improved, and living conditions have been greatly improved. In order to improve the anti-theft performance, anti-theft doors are basically used for entry doors. At present, anti-theft door manufacturers, in addition to adding anti-prying structures on door frames and door leaves, anti-theft locks generally adopt automatic anti-theft locks that are easy to unlock, convenient to lock, and good in anti-prying performance. The automatic anti-theft lock includes a shell, a panel, a deadbolt assembly, an oblique tongue touch trigger component, an elastic push mechanism, a touch trigger mechanism, and an unlocking mechanism. The guide post matches the guide groove on the bottom plate of the housing, and the trigger mechan...

AI Technical Summary

Problems solved by technology

[0003] 1. The bolt opening and positioning mechanism and the locking and anti-retraction mechanism of the above-mentioned automatic door lock have complex structures, which makes the above-mentioned automatic door lock high in manufacturing cost;

[0004] 2. The cooperation between the above-mentioned gear and the rack requires high precision, and the frictional resistance is large. The unlocking force of the main transmission part and the lock head is large, which makes the operation of the above-mentioned automatic door lock laborious.
