[0002] The rolling gate, also known as the "rolling shutter door", is a door formed by connecting a plurality of door panels with many joints in series and rotating up and down around the reel above the door in a fixed slideway. The rolling gate is applicable to commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or residences. Since the curtain of the rolling gate is relatively thin and only fixed at both ends in the track, when the curtain is blown by the wind in the horizontal direction, the curtain is prone to deformation.

When in use, the wind-resistant vertical rods are slid along the transverse guide rails to the target position, and when in the non-use state, all the wind-resistant vertical rods are slid to one side or both sides of the transverse guide rails, which is convenient to operate, realizes rapid deployment and storage, and occupies a small space during storage.

[0004] Although the above patent discloses the wind-resistant structure of the rolling gate, the use of the wind-resistant structure is relatively cumbersome.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a wind-resistant device for rolling gates, including a wall 1, on which a mounting bracket 8 is fixed. Inside the mounting bracket 8, a reel box 2 is installed. Inside the reel box 2, a curtain 3 is installed. Both side edges of the curtain 3 are connected in the guide rails fixed on the wall 1. Outside the mounting bracket 8, a driving motor 9 is installed. The driving motor 9 drives the rotating shaft for winding the curtain 3 inside the reel box 2 through a driving shaft 16.

[0023] On the inner side of the curtain 3, a strengthening component for enhancing the strength of the curtain 3 is provided. Outside the strengthening component, a driving rod 7 is connected. The driving rod 7 is installed on a bearing seat, and the bearing seat is fixed on the wall 1. On the driving rod 7, an adjusting component for changing the shape of the strengthening component is provided.

[0024] Further, a driven gear 19 is installed at the upper end of the driving rod 7. The driven gear 19 is connected to a driving gear 17 through a transmission gear set 18. The driving gear 17 is fixed on the driving shaft 16. A fixed connection is provided between the driving shaft 16 and the output shaft of the driving motor 9. The transmission gear set 18 is installed inside the mounting bracket 8, which can ensure that while the driving motor 9 winds the curtain 3, the synchronous transmission of the driving rod 7 is completed, enabling the driving rod 7 to work synchronously, and further realizing the position adjustment of the chain 4 to adapt to the winding of the curtain 3.

[0025] Further, the strengthening component includes a chain 4. Two chains 4 are arranged in a cross shape on the inner side of the curtain 3. At the intersection of the two chains 4, a connecting sleeve 15 is connected. And a bearing connection is provided between the connecting sleeves 15 on the two chains 4, which can ensure the stable cross state of the two chains 4 and also avoid the adverse effects between the two chains 4 when they move.

[0026] Even further, a first protective sleeve 13 is sleeved on the chain 4, and a second protective sleeve 14 is provided on the outer side of the connecting sleeve 15. Both the first protective sleeve 13 and the second protective sleeve 14 are made of EPE material, which can effectively avoid the direct collision between the chain 4 and the curtain 3, ensuring the working safety of the curtain 3, reducing noise, and improving the practical value of the chain 4.

[0027] Further, the adjusting component includes a moving seat 5, a winding wheel 6, and a driving rod 7. The upper end of the chain 4 is wound inside the winding wheel 6, and the lower end of the chain 4 is connected to the moving seat 5. Both the winding wheel 6 and the moving seat 5 are connected to the driving rod 7 to realize the position adjustment of the chain 4.

[0028] Even further, the winding wheel 6 is fixedly installed on the wall 1 beside the driving rod 7 in a rotatable state. A worm gear 20 is fixed inside the winding wheel 6, and a worm 21 is connected to the outer side of the worm gear 20. The worm 21 is fixedly arranged on the driving rod 7, which can make the winding wheel 6 rotate through the driving rod 7, and further realize the winding work of the winding wheel 6 on the chain 4.

[0029] Furthermore, the lower end of the chain 4 is hung on the moving seat 5 through the hook 11, which facilitates the disassembly between the chain 4 and the moving seat 5. The moving seat 5 is threadedly connected to the driving rod 7, and a limiting baffle 10 is connected to the rear side of the moving seat 5. The up and down position movement of the moving seat 5 can be realized by rotating the driving rod 7. A spring 12 is also arranged between the chain 4 and the hook 11, which can not only increase the elasticity when the length of the chain 4 changes during the winding of the chain 4, but also ensure the stable connection state between the chain 4 and the moving seat 5.

[0030] Specifically, when using this rolling shutter wind resistance device, first install the reel box 2 and the curtain 3 on the inner side of the doorway of the wall 1 through the mounting frame 8. After completing the connection and fixation of each part on the driving rod 7, when the wind resistance device is assembled, cross-set the chains 4, and sleeved with the first protective sleeve 13, the second protective sleeve 14, and the connecting sleeve 15 on the chains 4 to ensure the stability of the cross state of the chains 4. Finally, through the connection between the hook 11 and the moving seat 5, ensure that the chains 4 can carry out normal wind resistance work;

[0031] When lowering the curtain 3, the driving motor 9 drives the rotating shaft for winding the curtain 3 in the reel box 2 through the driving shaft 16, and then the curtain 3 can be lowered. While the driving shaft 16 rotates, through the driving gear 17, the transmission gear set 18, and the driven gear 19, the synchronous transmission of the driving rod 7 can be realized. When the driving rod 7 rotates, the moving seat 5 will move up and down on the driving rod 7. At the same time, the winding wheel 6 will also rotate under the transmission of the worm gear 20 and the worm 21. Therefore, when the position of the moving seat 5 moves up, the working length of the chain 4 will become shorter, and the winding wheel 6 will synchronously wind the chain 4 to make the chain 4 in a straightened state. At the same time, there is a spring 12 on the chain 4. When adjusting the working position of the chain 4, the winding length of the winding wheel 6 and the change in the working length of the chain 4 when the moving seat 5 moves. If there is a size mismatch, the existence of the spring 12 can provide length tolerance for the extension of the length of the chain 4 to ensure the normal change of the working size of the chain 4. At the same time, the existence of the spring 12 can also ensure that the chain 4 is in a taut state and is also convenient for the disassembly and assembly between the hook 11 and the moving seat 5;

[0032] In the above way, while the curtain 3 is being wound up, the driving rod 7 can drive the chain 4 to move its working position to match the working size of the curtain 3, so that there will be no problem of affecting the entrance and exit, and there is no need to separately control the wind resistance device to work.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
