DETAILED DESCRIPTION

The top of the first connecting column 23 is fixedly connected with a second pin 26.

[0027] N groups of second wind-resistant mechanisms 3 are installed in each door panel between the top door panel and the bottom door panel of the industrial lifting door. The second wind-resistant mechanism 3 includes a second mounting tube 31, a second limiting ring 32, and a second connecting column 33. The second mounting tube 31 is provided with a second piston hole 34 extending axially along the second mounting tube 31. The second limiting ring 32 is installed at the bottom of the second piston hole 34. The second connecting column 33 is sleeved in the second piston hole 34. The bottom end of the second connecting column 31 is fixedly connected to a third pin column 35. The bottom of the third pin column 35 passes through the second limiting ring 32 from top to bottom.

[0028] N ground limiting grooves 201 are provided on the ground 200 below the door opening of the industrial lifting door 100 .

[0029] The length of the first mounting tube 21 is equal to the height of the door panel 101 of the industrial lifting door 100, and the length of the first mounting tube 21 is equal to the thickness of the first limiting ring 22, the length of the first connecting column 23, and the length of the second pin 26; the diameter of the first connecting column 23 is smaller than the aperture of the first piston hole 24, the diameter of the first connecting column 23 is larger than the inner diameter of the first limiting ring 22, and the diameter of the first pin 25 is smaller than the inner diameter of the first limiting ring 22.

[0030] The length of the second mounting tube 31 is equal to the height of the door panel 101 of the industrial lifting door 100, and the length of the second mounting tube 31 is equal to the thickness of the second limiting ring 32, the length of the second connecting column 33, and the length of the third pin 35; the diameter of the second connecting column 33 is smaller than the aperture of the second piston hole 34, the diameter of the second connecting column 33 is larger than the inner diameter of the second limiting ring 32, the diameter of the third pin 35 is smaller than the inner diameter of the second limiting ring 32, and the diameter of the second pin 26 is smaller than the inner diameter of the second limiting ring 32.

[0031] The diameter of the ground limit groove 201 is greater than the diameter of the first pin 25 , the length of the first pin 25 is at least three times the depth of the ground limit groove 201 , the length of the first pin 25 is less than the length of the second pin 26 , and the length of the second pin 26 is equal to the length of the third pin 35 .

The second pin is contracted and accommodated in the first piston hole, and the third pin is contracted and accommodated in the second piston hole. The first wind-resistant mechanism is separated from the ground and the adjacent second wind-resistant mechanism, and the second wind-resistant mechanism is separated from the adjacent second wind-resistant mechanism and the wind-resistant beam.

[0035] When the industrial lifting door is closed, the first pin column moves upward due to the obstruction of the ground limit groove, driving the first connecting column and the second pin column to move upward, and the top of the second pin column is inserted into the bottom of the second piston hole, thereby lifting the second connecting column upward, so that the second connecting column and the third pin column move upward, and then the top of the third pin column is inserted into the bottom of the adjacent second piston hole or the pin hole.
