[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the load-bearing structure also includes a positioning groove 21, a slide groove 22 and an auxiliary groove 23. The positioning groove 21 is opened through the bottom of the base top 20, the slide groove 22 is also opened through the bottom of the base top 20, and the auxiliary groove 23 is opened through the front wall of the base top 20. The positioning groove 21 is evenly opened at the bottom of the base top 20. A plurality of the same positioning grooves 21 are opened, all of which can be connected with the slide groove 22. The slide groove 22 can adapt to the sliding of the card plate 31. The upper slide plate 32 is located at the bottom of the cavity of the base top 20 and slides. The card plate 31 is a convex block, the card plate 31 can be inserted into the card slot 21, the upper slide 32 can slide in the auxiliary slot 23, the load-bearing structure also includes a lock slot 24, a shift slot 33, a limit ring 34, a shift column 35 and a linkage ball 36. The lock slot 24 is evenly opened at the bottom of the base 20, the shift slot 33 is opened through the top of the bottom slide 30, the limit ring 34 is fixedly connected in the shift slot 33, the limit ring 34 is annular, the shift column 35 is slidably connected in the cavity of the limit ring 34, and the linkage ball 36 is symmetrically fixed to the shift column 35. The upper and lower walls of the load-bearing structure also include a bullet groove 41, a collar 42, a bullet column 43, a head 44 and a bullet bottom 45. The bullet groove 41 is opened at the top of the load-bearing rod 40, the collar 42 is fixedly connected to the bullet groove 41, the collar 42 is hollow and tubular, the bullet column 43 is slidably connected to the collar 42 cavity, the head 44 is fixedly connected to the top of the bullet column 43, the bullet bottom 45 is fixedly connected to the bottom of the bullet column 43, and the bottom of the bullet bottom 45 is also elastically connected in the bullet groove 41 by a spring. The head 44 and the linkage ball 36 are both hemispherical. The lock groove 24 can adapt to the size of the linkage ball 36, the shift groove 33 can adapt to the sliding of the linkage ball 36, the position of the linkage ball 36 is aligned with the position of each lock groove 24, the head 44 can contact the linkage ball 36 at the bottom of the shift column 35 through the rotation of the load-bearing rod 40, the elastic groove 41 can adapt to the sliding of the head 44 and the elastic bottom 45, and the bottom of the base 20 is symmetrically arranged with the upper slide 32, the clamping plate 31, the bottom slide 30, the shift column 35, the linkage ball 36, the load-bearing rod 40, the head 44, the elastic column 43 and the elastic bottom 45;

[0033] When the door is closed, the supporting rod 40 is pushed in the direction of the slide groove 22, and the supporting rod 40 can drive the bottom slide 30, the card plate 31 and the upper slide 32 to move at the same time. The card plate 31 can be released from the original card slot 21 and is locked in the card slot 21 due to the movement of the supporting rod 40 and is located in the slide groove 22. At this time, the supporting rod 40 is slid along the bottom of the base top 20 to the required position and stopped, and the supporting rod 40 is pulled in the direction of the card slot 21. At this time, the card plate 31 is locked in the card slot 21 of the corresponding position, and then the linkage ball 36 is at the vertical bottom of the lock groove 24. At this time, the supporting rod 40 can be rotated to make the elastic rod 47 contact the wall of the door. At this time, the position of the elastic bottom 45 will move to the vertical bottom of the linkage ball 36 due to the rotation of the supporting rod 40.

At this time, the linkage ball 36 will drive the shift post 35 and the linkage ball 36 at the top of the shift post 35 to move simultaneously when being pushed. The linkage ball 36 at the top of the shift post 35 will be stuck in the lock groove 24 due to the upward movement, thereby fixing the position of the load-bearing rod 40. When it is necessary to cancel the interference with the rolling shutter door, the load-bearing rod 40 can be rotated to its original angle. At this time, the elastic rod 47 will not interfere with the rolling shutter door, and the shift post 35 and the linkage ball 36 will also move downward due to the misalignment with the head 44, so that the position of the card plate 31 can be cancelled. At this time, the load-bearing rod 40 can be pushed and slid on the base top 20 to a place where it does not hinder pedestrians.

[0034] To sum up, by setting up the load-bearing structure, the rolling shutter door can be quickly adjusted to a state that improves its wind resistance. When in use, the load-bearing structure only needs to pull and rotate the load-bearing rod 40 to fix and unlock the position of the load-bearing rod 40 and the clamping plate 31, and there is no need to bend down to directly adjust the load-bearing rod 40. Therefore, compared with the existing technology, this solution is more convenient and quick when adjusting the device.

[0035] like Figure 1 and Figure 5 As shown, a resistance spring 46 is fixedly connected to one side wall of the load-bearing rod 40, and an elastic rod 47 is fixedly connected to the wall surface of the resistance spring 46. The resistance spring 46 is spring-shaped, and multiple identical resistance springs 46 are evenly arranged on the wall surface of the load-bearing rod 40. The elastic rod 47 is a semicircular rod, and the plane of the elastic rod 47 and the wall surface of the load-bearing rod 40 are connected by the resistance spring 46.

[0036] In actual use, when the elastic rod 47 contacts the rolling shutter door due to the rotation of the load-bearing rod 40, the contact spring 46 will be compressed due to the characteristics of the spring and contact the elastic rod 47 towards the rolling shutter door;

[0037] To sum up, by setting up an elastic elastic rod 47, the rolling shutter door can be resisted when the load-bearing rod 40 is fixed, and by resisting the rolling shutter door, the rolling shutter door can be prevented from directly colliding with the load-bearing rod 40 when subjected to strong winds, thereby reducing the service life of the rolling shutter door. Therefore, the elastic rod 47 can reduce the wear of the rolling shutter door when it is blown by strong winds.

[0038] A rolling shutter door, not shown in the figure, includes a rolling shutter door body and all of the above-mentioned wind-resistant mechanisms, with a base top 20 fixedly mounted on the rear wall of the rolling shutter door body;

[0039] By setting up a wind-resistant mechanism, not only can the wind-resistant strength of the rolling shutter door be improved, but also the wear of the rolling shutter door when blown by strong winds can be reduced.

[0040] When the door is closed, the supporting rod 40 is pushed in the direction of the slide groove 22.

The card plate 31 can be released from the original card slot 21 and is located in the slide groove 22 due to the movement of the supporting rod 40. At this time, the supporting rod 40 is slid along the bottom of the base 20 to the desired position and then stopped. The supporting rod 40 is pulled in the direction of the card slot 21. At this time, the card plate 31 is locked in the card slot 21 at the corresponding position, and then the linkage ball 36 is at the vertical bottom of the lock groove 24. At this time, the supporting rod 40 can be rotated to make the elastic rod 47 contact the wall of the door. At this time, the position of the elastic bottom 45 will move to the vertical bottom of the linkage ball 36 due to the rotation of the supporting rod 40. At this time, the spring at the bottom of the elastic bottom 45 will push the elastic bottom 45 upward to contact the elastic bottom The spring post 43 is moved in the cavity of the ring 42 at the same time, and the spring post 43 is moved in the cavity of the ring 42 at the same time, and the spring post 43 is moved in the cavity of the ring 42 at the same time, and the head 44 is extended upward from the elastic groove 41 and pushes the linkage ball 36 at the bottom of the shift post 35 upward. At this time, the linkage ball 36 will drive the shift post 35 and the linkage ball 36 at the top of the shift post 35 to move at the same time when being pushed. The linkage ball 36 at the top of the shift post 35 will be stuck in the lock groove 24 due to the upward movement, thereby fixing the position of the load-bearing rod 40. When it is necessary to cancel the conflict with the rolling shutter door, the load-bearing rod 40 can be rotated to its original angle. At this time, the elastic rod 47 will not conflict with the rolling shutter door, and the shift post 35 and the linkage ball 36 will also move downward due to the misalignment with the head 44, so that the position of the card plate 31 can be cancelled. At this time, the load-bearing rod 40 can be pushed and slid on the base top 20 to a place where it does not hinder pedestrians.
