Abstract

The invention discloses an important warehouse door main equipment integrated overlapped mechanical opening device. The important warehouse door main equipment integrated overlapped mechanical openingdevice comprises an overlapped device installation plate movably installed to the inner side face of a warehouse door, the installation plate is provided with a plurality of parallel door pin devicesmatched with door pin holes inside a warehouse door frame, the overlapped device installation plate is internally provided with a plurality of parallelly-arranged long-strip holes from top to bottom,the long-strip holes are internally provided with bearings which can be clamped inside the long-strip holes and roll in the length direction of the long-strip holes, the bearings are fixedly installed to the inner side face of the warehouse door through shafts with one ends being fixed to the inner rings of the bearings, the overlapped device installation plate is fixedly provided with a toothedbar arranged in the horizontal direction, a gear engaged with the toothed bar is installed to one end of a gear shaft, the gear shaft is fixedly connected with an external hand wheel after penetratingthrough a long-strip-shaped shaft hole inside the overlapped device installation plate and the warehouse door in sequence, the overlapped device installation plate is further provided with a position-limiting rod, and the position-limiting rod is provided with a lock hole matched with a lock tongue of a mechanical code lock on the warehouse door. By means of the important warehouse door main equipment integrated overlapped mechanical opening device, the labor cost is reduced, operations are convenient, and the safety performance is high.

Description

technical field [0001] The invention relates to a mechanical opening device with integrated main and standby parts for an important warehouse door. Background technique [0002] The warehouse door is a special protective gate for the warehouse area of ​​banks, stock exchanges, gold stores and other industries. It is used in manufacturing, materials and [0003] The performance requirements far exceed the requirements of anti-theft doors, and are mainly used for anti-theft, anti-drilling, fire prevention, and waterproof. The warehouse door with intelligent control lock adopts an electrical control system. When the control system fails due to power failure or accident, the door lock cannot be opened, which will affect the use. [0004] Existing warehouse door relock mechanism, such as Chinese patents CN 209538908 U, CN 110056268 A, etc., its relock mechanism is mainly to ensure safety, that is, when the warehouse door or lock is damaged by external force, the door lock is rel...
