Embodiment approach
[0013] When the wire rope breaks, the stage clip 4 resets, drives the T-shaped plate 1 to move downward, drives the rotating plate 5 to rotate through the bearing pin 4, and makes the brake plate 7 rotate inwardly to bite the track, thereby fixing the door body on the track.
[0014] The invention is simple in structure, easy to use and install, makes the door body run more smoothly, prevents it from falling, and ensures that the door body will not fall and accidentally injure the operator. 290, a large flexible door with a total door weight of 5T~10T.

The invention relates to an anti-falling protection device for a flexible door. The anti-falling protection device comprises a T-shaped plate, wherein the middle part of a base has a hollow structure; the base is provided with a guide shaft; shaft pins are symmetrically arranged on both sides of the lower end of the T-shaped plate; a pressure spring is sleeved on the guide shaft; the pressing spring is positioned in the hollow structure of the base; the two shaft pins are connected with transmission shafts through rotating plates; the transmission shafts are provided with braking vanes; the rotating plates, the transmission shafts and the braking vanes are connected through keys. The anti-falling protection device has the advantages of simple structure, convenience in installation, use and running, running smoothness and higher safety.
Description
technical field [0001] The invention relates to an anti-sliding device, in particular to an anti-falling protection device for a flexible door. Background technique [0002] At present, due to the inconvenient maintenance and disassembly of traditional upward sliding doors, poor sealing performance, and poor anti-theft performance, flexible doors have been widely used, but the springs in the falling device of this flexible door, after repeated use, are very It is easy for the spring to lose its elasticity, and the steel wire rope accidentally breaks and the door body falls, which causes potential safety hazards for operators and affects normal use and promotion. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a more secure flexible door anti-drop protection device with smooth operation. [0004] The purpose of the present invention is achieved through the following technical solutions: a flexible do...
