Inclined tongue mechanism of core insertion lock

Abstract

The invention discloses an inclined tongue mechanism of a core insertion lock. The mechanism comprises an inclined tongue component, an inclined tongue reset spring, a triggering tongue component, a triggering tongue reset spring, a trigger and a trigger reset spring, wherein the trigger is slidbly arranged on a lock shell; the inclined tongue component is provided with an inclined tongue limiting face, and the trigger is provided with a first matching portion which is used for being matched with the inclined tongue limiting face; when the trigger is pressed toward the trigger reset spring, the first matching portion breaks away from the inclined tongue limiting face; the triggering tongue component is provided with a first protruding block, and the trigger is provided with a second matching portion which extends between the tongue end of the triggering tongue component and the protruding block. Through the structural format of the inclined tongue mechanism, when a door is closed, the triggering tongue component is pressed into the lock shell, thereby the protruding block is made to break away from the second matching portion, meanwhile, the inclined tongue component extends out of the lock shell under the action of the inclined tongue reset spring, the trigger resets finally, and the first matching portion, the inclined tongue limiting face and the inclined tongue component are locked; when the trigger resets, the trigger can be further interlocked with other mechanisms of the core insertion lock, and the other mechanisms are controlled to act.

Description

technical field [0001] The invention relates to a mortise lock, and specifically designs a slant bolt mechanism of the mortise lock. Background technique [0002] The mortise lock is also called the mortise door lock. It is generally composed of three parts: a handle, a lock cylinder and a lock body. It is mostly installed on indoor suit doors and anti-theft doors. It is also one of the most common locks on the market. The existing mortise locks mainly include single dead tongue mortise locks, single dead tongue button mortise locks and double tongue mortise locks, wherein the double tongue mortise locks are equipped with dead tongues and oblique bolts, and their anti-theft performance is better than that of single dead tongues. Mortise locks and single-bolt button mortise locks are high, and can be divided into single-action mortise locks, double-action mortise locks and quick-release mortise locks according to the function of the handle, which are easy to use.

AI Technical Summary

Problems solved by technology

It solves the problem that the existing mortise lock cannot be automatically locked after closing the door, and the main bolt needs to be protruded by using a key or rotating the outer door handle, which makes it inconvenient to use the mortise lock
