False mortise single-hook movable door lock

Abstract

A false mortise single-hook movable door lock comprises a casing consisting of a base plate, a cover plate and a lining plate, wherein a shifting yoke, a sliding plate, a hook body and a gyration spring are arranged in the casing, and a transmission sheet, a touch tongue and a return spring capable of driving the transmission sheet to return downwards are arranged on the base plate; the touch tongue is arranged above the hook body, a tongue hole is formed in the lining plate, a horizontal sliding column is arranged at the rear end of the touch tongue, and a sliding hole is formed in the base plate; and a gear position is arranged at the lower end of the transmission sheet, and an oblique action platform extends upwards from the upper end of the transmission sheet. The false mortise single-hook movable door lock adopts the technical scheme that a closed moving door acts on the touch tongue and enables the touch tongue to slide into the casing to enable the transmission sheet to slide upwards, as a result, the moving door is locked by rotating a key after the locking realized by the swinging towards the hook body of the shifting yoke is released, and further, situations that when the moving door is not closed, the hook body is driven to swing out of a lock body on account of the misoperation of the key and the moving door collides with the front face of the hook body are avoided. Therefore, the false mortise single-hook movable door lock is reasonable in structure, can improve operation safety of door looking, and is more practical and humanized.

Description

【Technical field】 [0001] The invention relates to a lock body, in particular to a single-hook movable door lock body with a false core. 【Background technique】 [0002] The current single-hook movable door lock body mainly includes a housing, a shift fork, a slide plate and a hook body which are arranged in the housing and interlock with each other. Sliding horizontally in the direction of the liner to make the hook body swing outwards and then hook into the moving door, so as to achieve the purpose of locking the door. Because in the daily use process, there may be the situation of locking the door by mistake, that is, when the movable door is not closed, sometimes the door lock is operated to make the hook body swing out of the lock body. It will cause the movable door to hit the front of the hook body, thereby easily damaging the movable door or the lock, so the structure of the current single-hook movable door lock body is unreasonable. 【Content of invention】 [0003]...
