Post-trigger type door leaf linkage structure

Abstract

The invention discloses a post-trigger type door leaf linkage structure, which comprises a door leaf, a main lock body, a connecting rod assembly, an anti-theft lock point assembly, and a contactor. The connecting rod assembly comprises a horizontal connecting rod assembly and a longitudinal connecting rod assembly connected with each other; the contactor is arranged at the rear end of the horizontal connecting rod assembly and is located on the inner side of the door leaf; the contactor drives the longitudinal connecting rod assembly to move outwards through the horizontal connecting rod assembly and drives the anti-theft lock point assembly to lock; and the main lock body drives the connecting rod assembly to move inwards and drive the anti-theft lock point assembly to unlock. Accordingto the post-trigger type door leaf linkage structure provided by the invention, through arranging the contactor on the inner side of the door leaf, a transmission pressure of the main lock body is reduced, and the wear of parts in the main lock body during a use process is reduced; and on the other hand, a function of the main lock body for locking the anti-theft lock point assembly is separated out, so that an inner structure of the main lock body is simplified, the occurrence of the phenomenon of excessive deformation of the parts in the main lock body caused by frequent door opening, door closing and locking during a use process is prevented, and the service life of the main lock body is reduced.

Description

technical field [0001] The invention relates to a door leaf interlocking structure, in particular to a rear trigger type door interlocking structure. Background technique [0002] At present, most of the anti-theft doors on the market use the method of adding lock points to improve the anti-theft performance, that is, adding a world lock on the basis of the main lock body, or further setting lock heads at the four corners of the door leaf, thereby improving the safety of the anti-theft door. Anti-theft performance, in order to ensure the linkage accuracy of the lock head, the control of the lock heads distributed in the four corners is usually realized by setting the connecting rod assembly, one end of the connecting rod assembly is connected with the lock head, and the other end is connected with the main lock body Connected, the main lock body drives the connecting rod assembly to drive the locking and unlocking of the lock head. [0003] However, there is also a relative...

Problems solved by technology

[0004] The present invention aims at the high production cost and difficult processing of the main lock body caused by the complex structure of the internal transmission mechanism of the main lock body existing in the prior art, and the setting of the lock head Due to the defects of high transmission pressure of the main lock body and easy wear and tear inside the main lock body caused by dispersion, a new rear-triggered door leaf interlocking structure is provided.
