Cabinet linkage door lock

Abstract

The invention discloses a linkage door lock for a cabinet. The linkage door lock comprises a locking device, a driving device, a guiding device and a hand wheel, wherein the locking device comprises a first locking assembly and second locking assemblies, the first locking assembly comprises a first body and a first bolt; one second locking assembly on any side comprises a second body and second bolts which are positioned on the second body and arranged oppositely; the driving device comprises a first driving rod, a second driving rod and third driving assemblies which are arranged oppositely; the guiding device comprises a first guiding assembly which is used for guiding the first bolt, and a second guiding assembly which is used for guiding second bolts on the two sides; the linkage door lock for the cabinet further comprises a limiting device which is used for limiting the movement stroke of the locking device. According to the linkage door lock for the cabinet provided by the invention, since a plurality of linkage locking points are arranged, the locking force is enhanced; the movement stroke of the locking device is controlled in a limiting mode, so that the direct contact with the locking device is avoided, and the damage probability of the linkage door lock for the cabinet is reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a cabinet linkage door lock used for oil exploitation. Background technique [0002] At present, the door locks of outdoor cabinets are mainly three-point linkage type. Specifically, the door lock is a link lock, which includes a lock rod and a round steel. The lock rod is plated with 3MM flat iron or 10MM round steel. The lock rod is directly connected and fixed. way, and open the door through the transmission of the lock cylinder. However, due to the particularity and uncertainty of the use environment of outdoor cabinets, the anti-theft performance requirements of outdoor cabinets are very high. Under this requirement, from the actual use situation, there are potential safety hazards in the three-point linkage door lock. Among them, the 3MM lock rod or 10MM round steel will rust after a period of use, which will lead to the use of the lock rod. The service life is shortened, and the lock lever is ...

Problems solved by technology

Under this requirement, from the actual use situation, there are potential safety hazards in the three-point linkage door lock. Among them, the 3MM lock rod or 10MM round steel will rust after a period of use, which will lead to the use of the lock rod. The service life is shortened, and the lock lever is directly connected and fixed, which increases the probability of damage to the door lock

At the same time, the locking strength of the three-point linkage door lock is limited, and it is easy to be damaged under the action of external force
