Problems solved by technology

The rigid link mode used by traditional door locks will not only increase the weight of the door lock itself, resulting in laborious opening and closing, but also because of the heavy weight of the door itself, the collision force during the opening and closing process will be relatively large, causing the lock tongue to directly The force is transmitted to the linkage rod with a small slenderness ratio, causing deformation and damage to the linkage rod and the opening device

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] The invention includes four parts: a door top lock point unit, an opening unit, a door bottom lock point unit and a linkage unit. The original intention of the design is to consider the door top lock unit, the opening unit, and the door bottom lock unit separately, and then use the steel wire cable 20 combined with the cable tube 24 as the linkage unit to effectively reduce the weight of the door lock device itself and at the same time maximize the ...

Abstract

The invention relates to a door lock device of a super-large door. The door lock device comprises a door top lock point unit, an opening unit, a door bottom lock point unit and a linkage unit, and thedoor top lock point unit and the door bottom lock point unit are both connected with the opening unit through the linkage unit, are of the same structure and are each provided with a spring bolt, a stress rebound spring and a spring bolt connecting rod connected with the spring bolt; the linkage unit comprises a steel wire drawing line, the steel wire drawing line is connected with the opening unit, the opening unit controls the spring bolt connecting rods through the steel wire drawing line to drive the spring bolts to conduct the unlocking action, and the stress rebound springs reset to complete locking action. Compared with the prior art, the door lock device has the advantages of being simple in structure, capable of saving labor during unlocking and locking, low in damage probability, convenient to maintain, flexible in arrangement and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical door locks, in particular to a super-large door lock device. Background technique [0002] There are countless large-scale venues currently in use or under construction. People gather here to get what they need. As the number increases, the volume is also changing proportionally. Various super-large doors are born from this. After many times of opening and closing, the reliability of the door lock has become increasingly prominent. The rigid link mode used by traditional door locks will not only increase the weight of the door lock itself, resulting in laborious opening and closing, but also because of the heavy weight of the door itself, the collision force during the opening and closing process will be relatively large, causing the lock tongue to directly The force is transmitted to the linkage rod with a very small slenderness ratio, causing deformation and damage of the linkage rod and the...
