Abstract

The invention provides a folding mechanism of a revolving door. The folding mechanism comprises a transmission shaft, a disk, a first connecting rod, a second connecting rod, a tightness adjusting device and a fixing plate, wherein the end surface of the disk is provided with an opening and fixedly connected with the transmission shaft, the first connecting rod and the second connecting rod are respectively and symmetrically positioned on two sides of a center shaft of the disk, and provided with protruding structures, the outer contour of the opening of the disk corresponds to that of each protruding structure, the tightness adjusting device is used for adjusting the degree of tightness between the protruding structures and the opening of the disk, and the fixing plate is provided with an installation part. Under the condition of an emergency, the combination between the disk and the connecting rods is loosened through the tightness adjusting device, a door leaf is forcefully pushed to drive the transmission shaft to rotate, the protruding structures are separated from the opening, and then the door leaf is folded so as to achieve the purpose of forming a barrier-free way.

Description

technical field [0001] The invention relates to a folding mechanism for a revolving door. Background technique [0002] As a door and window structure, the revolving door has the advantages of beautiful appearance and good sealing performance, and is widely used in various buildings in daily life. With the improvement of people's living standards, higher requirements are constantly put forward for the performance of revolving doors in terms of safety and convenience. [0003] At present, the relative positions between the door leaves of common revolving doors are fixed, and the size of the space formed by the door leaves is fixed. When there is an emergency such as a large number of people entering and exiting the building, if the personnel follow the door leaf to rotate and enter and exit the building, the speed of entering and exiting will be greatly affected. If a barrier-free passage can be formed in the revolving door, people entering and leaving do not need to pass t...
