Linkage door lock

Abstract

The invention discloses a linkage door lock. The linkage door lock comprises a door frame; a plurality of sliding door plates are arranged in the door frame; vertically-symmetrical side protruding blocks are arranged on one sides of the sliding door plates located on the two sides; a plurality of side fixing blocks are arranged in the door frame; the side fixing blocks are hinged to the side protruding blocks; inner cavities are formed in the sliding door plates. the adjacent sliding door plates extend into the inner cavities and are connected with the inner cavities in a sliding fit mode; open fixed slopes are arranged on the end faces of the sliding door plates; and the fixed slopes are symmetrically arranged. According to the linkage door lock, the equipment forms the sliding door in amutual sliding mode and can rotate; and moreover, when the lock is unlocked, locking and fixing between the sliding door plates on the two sides and the door frame can be unlocked to avoid the situation that a person unlocks the equipment for many times, so that the purpose of rapid and labor-saving unlocking is achieved.

Description

technical field [0001] The invention relates to the technical field of door lock equipment, in particular to a linkage door lock. Background technique [0002] There are many problems and defects in the existing door lock equipment. When opening and closing some relatively large doors, most of them adopt the telescopic sliding method to slide and fold several doors. When the sliding door is locked on both sides, the left and right doors on both sides need to be locked with the help of bolts, and the upper and lower sides of the door and the door frame are also locked. During this process, personnel need to pull the bolts at each position separately. Make the bolts in the door slide and retract into the door. Due to the large number of bolts, the personnel have to slide and twitch many times to slide all the bolts into the door and lock the door sequentially.

Problems solved by technology

[0002] There are many problems and defects in the existing door lock equipment. When opening and closing some relatively large doors, most of them adopt the telescopic sliding method to slide and fold several doors. When the sliding door is locked on both sides, the left and right doors on both sides need to be locked with the help of bolts, and the upper and lower sides of the door and the door frame are also locked. During this process, personnel need to pull the bolts at each position separately. Make the bolts in the door slide and retract into the door. Due to the large number of bolts, the personnel have to slide and twitch many times to slide all the bolts into the door and lock the door in turn. Or open, due to the existence of the above-mentioned shortcomings, if there are not many people who work together when people need to open the door urgently, it will be difficult to realize this process, making it difficult to guarantee the safety of people's lives and the reliability of the door lock.
