Description

Detachable rolling slats door anti-wind device Technical Field The invention belongs to the technical field of wind resistance of rolling doors, and particularly relates to a detachable wind resistance device of a rolling door. Background The rolling door is used as a common door body structure, is formed by sequentially connecting multi-joint curtain plates in series, can vertically rotate along a scroll in a fixed slideway, is widely applied to commercial and industrial places by virtue of the unique design, has excellent separation function, can effectively divide different areas, has good protective performance, can ensure the safety of articles and personnel in places, and has convenient operation characteristics, thereby being convenient for daily use. In the existing market environment, the rolling doors are widely applied to shops at two sides of various streets, the gates of the shops are positioned at two sides of the streets and are positioned in areas with more remarkable wind power influence, and due to the special geographic positions of the streets, air flows easily form vortex and accelerate at the places, so that the wind power born by the gates of the shops is large. Therefore, in the production process of the roller shutter door, the detection of the wind resistance effect is very important, and strict experimental verification is required; Along with the rapid development of modern technology, the wind-resistant function of the rolling shutter door is continuously optimized and perfected, the wind-resistant structure and related parts at the upper end of the rolling shutter door are continuously upgraded and improved, more advanced design concepts and materials are adopted to improve the wind-resistant performance, the rolling shutter door equipment can more stably defend the gate of each store, the attack of strong wind is effectively resisted, the damage risk caused by the strong wind is reduced, reliable guarantee is provided for the normal operation of the store, and therefore, the wind-resistant device for the rolling shutter door has very urgent practical requirements for research, development and production. However, the existing wind-resistant device for the roller shutter door still has the following disadvantages in the use process: 1. When the existing rolling shutter door wind-resistant device is used, the degree of automation is low, after the rolling shutter door is pulled down each time, a user needs to manually support the wind-resistant device on the rear side of the rolling shutter door, only when strong wind is coming, the device can effectively provide support on the rear side of the rolling shutter door through a baffle, and the risk of deformation and damage of the rolling shutter door is reduced, but the protection mode brings great inconvenience to the user, the additional time and effort are required to manually install the wind-resistant device when the rolling shutter door is pulled down, and the device is required to be manually stored before the rolling shutter door is opened, so that the whole operation process is complicated, the installation efficiency of the wind-resistant device is seriously influenced, and meanwhile, the operation burden of the user is increased; 2. Existing wind resistant devices for roller doors typically need to be mounted on the rear side of the roller door when in use. In the installation process, the device is usually required to be screwed and reinforced by various screws and other fasteners to ensure the stability of the device, or the whole wind-resistant device is welded on the door frame of the roller shutter door to ensure that the whole wind-resistant device cannot be dismantled, however, the installation mode can bring great trouble when the roller shutter door is maintained in the later period, and because the device is firmly installed and difficult to disassemble, maintenance personnel need to spend a great deal of time and effort to process the wind-resistant device when checking and maintaining the roller shutter door, the operation is very inconvenient, and the maintenance cost and time are increased. Therefore, it is necessary to invent a detachable wind-resistant device for roller shutter door to solve the above problems. Disclosure of Invention In view of the above, the present invention provides a detachable wind-resistant device for a roller shutter door, so as to solve the above-mentioned problems in the prior art. The detachable rolling shutter door wind-resistant device comprises a rolling shutter cover and two support rails, wherein an automatic wind-resistant mechanism, a quick dismounting fixing mechanism and a safety component are respectively arranged between the two support rails, the two support rails are fixedly arranged on two sides of the bottom of the rolling shutter cover, and the inner walls of one end of the two support rails are respectively communicated with the inner walls of two ends of the
