Escaping lock with improved structure

Abstract

The invention belongs to the technical field of locksets and provides an escaping lock with an improved structure. The escaping lock comprises a lock body base, a triangular bolt mechanism, an ox horn sheet assembly and a quadrangular bolt mechanism, wherein the triangular bolt mechanism is provided with an inner square rod and an outer square rod; the quadrangular bolt mechanism comprises a quadrangular bolt mechanism locking assembly and a blade assembly; a blade pulling block and a lever sheet are arranged between the blade assembly and the lever sheet; one end of the blade pulling block is matched with the blade assembly and the other end of the blade pulling block is matched with the triangular bolt mechanism; one end of the lever sheet is matched with the quadrangular bolt mechanism locking assembly and the other end of the lever sheet is matched with the quadrangular bolt mechanism locking assembly; and a linkage rod is further arranged between the quadrangular bolt mechanism locking assembly and the triangular bolt mechanism. The escaping lock has the advantages that the structure is simple and reasonable; unlocking operation can be carried out by only rotating for one ring and the linkage with other parts is less, so that the escaping lock is relatively stable and reliable when the escaping lock is opened for escaping; and therefore, the fault rate is greatly reduced and the escaping effect is good.

Description

technical field [0001] The invention belongs to the technical field of locks and relates to an escape lock with an improved structure. Background technique [0002] Escape locks are also called fire exit escape locks. They are mainly used on the emergency exit doors of large supermarkets, shopping malls, office buildings, hospitals, schools, factories and other public places with a large flow of people.

In recent years, fire departments have extremely high requirements for the safety of fire exits in shopping malls, supermarkets, schools, hospitals, and other places. New fire safety laws and regulations require public places A fire exit lock must be installed. The existing escape lock has complex internal structural parts. When the handle is opened, it needs to be rotated more than two times to unlock, and the movement of the lock tongue is not very flexible, so the failure rate is relatively high. may fail to achieve the purpose of escape at a critical time
