Linkage door

Abstract

The invention relates to an industrial door, a sliding-lifting door and application of the industrial door and the sliding-lifting door which serve as translation linkage doors and provides a linkage door which is compact in structure, reliable and sensitive in operation, high in efficiency and capable of achieving synchronous differential. The linkage door comprises a door frame, a lifting device and door bodies from a first door body to a last door body, wherein the door bodies are parallelly arranged from the outside to the inside. The door frame comprises a door head and a door leaf guide rail. The door bodies from the first door body to the last door body are connected through synchronous differential mechanisms, and the lifting device is connected with any of the door bodies. The synchronous differential mechanisms include a first synchronous differential mechanism for the door bodies from the first door body to a last but one door body and a second synchronous differential mechanism for the last door body. The first synchronous differential mechanism comprises a belt wheel device, a front connecting rod and a rear connecting rod. The second synchronous differential mechanism for the last door body comprises a belt wheel device and a front connecting rod. The synchronous differential mechanisms are arranged among the door bodies of the linkage door so that synchronous movement is achieved in the opening or closing process of the door bodies.

Description

technical field [0001] The invention relates to an industrial door, a sliding door and its application as a translation linkage door. Background technique [0002] Industrial doors are divided into: industrial rolling doors, industrial sliding doors, manual / electric sliding doors, fast rolling doors and other types. Industrial sliding doors are divided into vertical lifting, standard lifting and high lifting; while electric sliding doors switch horizontally from the middle to both sides. Which industrial door opening method to use will depend on the analysis of the specific conditions and development requirements of the workplace, and the design of each industrial door has unique characteristics and advantages. [0003] Industrial lifting doors are composed of a series of door panels (commonly made of metal or cloth materials, etc.), which rise along the track, and the balance of the door body is guaranteed by the torsion spring system or the counterweight system.

Problems solved by technology

[0004] The industrial doors in the aforementioned prior art generally have the following characteristics in terms of structure: one is that the multiple doors operate on their own tracks, which makes the cost high, the maintenance is difficult, and the smoothness of movement is difficult to control; the other is that the multiple doors Driven by their own driving mechanisms, the overall volume is large, the cost is high, and even the phenomenon of running disorder occurs (some doors move, some doors do not move); third, the integrity is poor, the installation is difficult, and the doors cannot be reused (such as When the door is disassembled and used in another occasion, once the multi-track structure of the prior art is disassembled, it is difficult to maintain the accuracy of the next use); the fourth is the sensitivity and reliability of the operation.
