Wind Resistant Roller Shutter

Abstract

The invention discloses a wind-resistant rolling gate. The wind-resistant rolling gate comprises a door frame, a rotating shaft and a door curtain, wherein the door frame is fixed to an external building, the rotating shaft is rotatably arranged on the upper side edge of the door frame, the upper side edge of the door curtain is fixedly connected with the side surface of the rotating shaft, the door curtain is hollow, reinforcing ports are formed in the left side and the right side of the door curtain, a sliding groove extending along a transverse rod are formed in the lower side edge transverse rod of the door curtain, two ends of the sliding groove communicate with the two reinforcing ports, rail grooves are formed in the left side and the right side of the door frame, the left side andthe right side of the door curtain are slidably arranged in the rail grooves, and telescopic reinforcing plates are arranged in the rail grooves. According to the wind-resistant rolling gate, throughthe arrangement of the reinforcing plates and the sliding groove, a manner that the reinforcing plates are plugged into the door curtain can be effectively achieved, so that the wind-resistant performance of the door curtain is enhanced.

Description

technical field [0001] The present invention relates to a rolling gate, more specifically to a wind-resistant rolling gate. Background technique [0002] The rolling gate is a relatively common door structure in the existing technology. It is mainly used in occasions requiring large doors. It has the characteristics of wide coverage area and low material cost, and can effectively realize the function of the door. [0003] The existing rolling gate structure mainly consists of three parts, specifically including a door curtain, a rotating shaft and a slide rail. The rotating shaft is rotatably installed on the upper side of the door frame. The upper side is fixed on the rotating shaft, and is rolled up or released by the rotating shaft through the rotation of the rotating shaft. The slide rail is fixedly installed on the left and right sides of the door frame, and then the left and right sides of the door curtain are slidably set in the slide rail. Through the limit function...

Problems solved by technology

[0003] The existing rolling gate structure mainly consists of three parts, specifically including a door curtain, a rotating shaft and a slide rail. The rotating shaft is rotatably installed on the upper side of the door frame. The upper side is fixed on the rotating shaft, and is rolled up or released by the rotating shaft through the rotation of the rotating shaft. The slide rail is fixedly installed on the left and right sides of the door frame, and then the left and right sides of the door curtain are slidably set in the slide rail. Through the limit function of the slide rail, the vertical lift on the slide rail is realized to open or close the door frame. Therefore, in order to allow the rotating shaft to be rolled up in the existing door curtain, the structure of the door curtain is composed of multiple horizontal bars. The horizontal bars are connected by soft iron sheets, so that through the deformation of the iron sheets, they can be wound on the rotating shaft. Therefore, the vertical structure of the door curtain is not very stable during the use process, so when the wind blows After being placed on the door curtain, the door curtain will swing due to the wind force. In this way, when the external wind force is strong, such as a typhoon, it is easy to cause the door curtain to swing violently and cause damage due to impact. Therefore, there is a problem in the prior art. A reversible and swingable vertical bar is set on the upper side of the door curtain to provide a vertical structural force by turning the vertical bar down to be perpendicular to the horizontal bar on the door curtain during typhoon weather. However, this structure can only provide the structural force of the contact part of the vertical rod, and the force exerted by the typhoon on the door curtain covers the entire door curtain. Therefore, in the process of typhoon weather, the door curtain still has the problem of being blown. Therefore, the existing The wind resistance of the rolling gate is not enough
