Lock block self-bouncing structure of anti-theft door lock

Abstract

The invention relates to a self-bouncing structure, in particular to a lock block self-bouncing structure of an anti-theft door lock. The lock block self-bouncing structure comprises a shell, a main bolt assembly, an inclined bolt assembly and a first fixing pin are arranged in the shell, a fixing sheet is arranged between the main bolt assembly and the first fixing pin, a second fixing pin is arranged on a first unlocking transmission sheet, a transmission mechanism comprises a second unlocking transmission sheet, the second unlocking transmission sheet is internally provided with an unlocking hook, and the second fixing pin and the unlocking hook have a linkage state and a non-linkage state; and in the linkage state, the second fixing pin abuts against the unlocking hook and pulls the second unlocking transmission sheet to achieve conversion from the locking state to the unlocking state. According to the lock block self-bouncing structure, on the basis that the structure strength ofan existing lock inclined bolt assembly, only several parts are increased for achieving the automatic locking function on a lock body; and seamless connection of a self-bouncing lock body and a commonlock body can be achieved, the die developing cost is saved, social cost is saved, and the beneficial effects of being simple in structure, convenient to machine and easy to assemble are achieved.

Description

technical field [0001] The invention relates to a self-bounce structure, in particular to a lock body self-bounce structure of an anti-theft door lock. Background technique [0002] The door is the guarantee of the home. Nowadays, anti-theft doors have entered thousands of households. The lock body of the ordinary anti-theft door is divided into the oblique tongue and the main tongue, while the self-elastic lock body on the market basically uses the movement of the oblique tongue to unlock Function, in order to make the lock have a self-elastic function, the structure of the connecting rod or connecting piece of the bolt is usually changed. However, the strength of the bolt after changing the strength cannot reach the 3000N required by the national standard or is far lower than the strength of the existing ordinary locks. How to realize the self-bounce function of the lock without changing the strength of the oblique tongue is the problem we need to solve now. Contents of ...
