Bolt locking mechanism cooperated with door handle control mechanism

Abstract

The invention relates to a lock tongue locking mechanism matched with a door handle manipulation mechanism, which comprises a locking part of a lock tongue member, a door handle mounting hole, a shaft sleeve, a mandrel of the door handle manipulation mechanism and a contilever plate, wherein the door handle mounting hole is molded in the position of a door lock shell corresponding to the door handle; the shaft sleeve of which the sidewall is provided with a through groove is arranged in the door handle mounting hole; the mandrel of the door handle manipulation mechanism can axially slide, is rotatably arranged inside the shaft sleeve and a lug boss; the mandrel is provided with a shifting block radially extending; the shifting block is suitable for sliding in the through groove; the extending length of the shifting block is greater than the thickness of the shaft sleeve and the sidewall of the lug boss; the contilever plate is pivotally arranged on a journal of the shaft sleeve through a shaft sleeve mounting hole molded on the contilever plate; the arched part of the shaft sleeve mounting hole corresponding to the shifting block is provided with a shifting groove; and the shifting block is embedded into the shifting groove. The lock tongue locking mechanism solves the technical problems that parts of the lock body are overmany and have small strength and the requirement of mounting precision is high, and is particularly suitable for an inserted core lockset.

Description

technical field [0001] The present invention relates to a deadbolt locking mechanism matched with a door handle operating mechanism, in particular to a device for manipulating or controlling the opening and closing process of the deadbolt through mechanical transmission. Background technique [0002] In the prior art, using a mechanical transmission mechanism to control the opening and closing of the door lock is the most common operating mechanism, especially the mechanism for opening and closing the door lock through a handle. [0003] In the past door lock with wedge-shaped deadbolt, the deadbolt is temporarily pushed back to the lock body through the impact of the deadbolt and the door frame. When the door is closed tightly, the deadbolt pops out under the action of bias force to lock the door. The dead bolt is easy to be pressed back to the lock body by the tool to open the locked door, the door lock is prone to accidental locking, and the state of the dead bolt is not ...

AI Technical Summary

Problems solved by technology

The multiple rotating parts in the lock body take up a lot of space, and the parts are scattered in the lock body, forcing the strength of the multiple parts in the limited space volume to be low; at the same time, because multiple parts need to cooperate with each other, the installation accuracy of the lock requires higher
