Wind resistance device for roller shutter door

Abstract

The invention discloses a wind resistance device for a rolling shutter door. The wind resistance device comprises a shutter door body and a winding drum, door frames are further arranged on the two sides of the shutter door body, a mounting seat is arranged on the side, back on to the winding drum, of the door frames, a mounting groove is formed in the mounting seat and comprises a first groove wall and a second groove wall, a supporting mechanism is arranged on the first groove wall and comprises a lead screw, a first thread and a second thread which are opposite in thread turning direction are arranged on the lead screw and are in threaded connection with a first sliding block and a second sliding block correspondingly, a guide rail is arranged on the second groove wall, and the first sliding block and the second sliding block are slidably connected to the guide rail; a first wind-resistant plate and a second wind-resistant plate which are centrally and mutually hinged are further arranged in the mounting groove, one end of the first wind-resistant plate is hinged to the first sliding block, one end of the second wind-resistant plate is hinged to the second sliding block, a driven wheel is arranged at the end, facing the first groove wall, of the lead screw and provided with a rotating shaft, and the rotating shaft is rotatably arranged on the first groove wall; and a drivingmechanism is arranged in the mounting groove, and a wind power sensor is arranged on the shutter door body.

Description

technical field [0001] The invention relates to a wind-resistant device, more specifically to a wind-resistant device for a rolling shutter door. Background technique [0002] The rolling shutter door is made of multi-joint movable door pieces connected in series. In the fixed slideway, the upper and lower doors are rotated around the reel above the door. Rolling shutter doors are usually widely used in shops. [0003] At present, various steel rolling shutter doors are most widely used at the entrance and exit of factories, but due to the structure of the rolling shutter door itself and other factors, its wind resistance will be limited, especially for super large and ultra wide rolling doors. As the wind area increases, its wind resistance will decrease accordingly. In the case of windy weather, the rolling shutter door is prone to deformation, and even causes damage to the shutter door, affecting subsequent use.

Problems solved by technology

[0003] At present, all kinds of steel rolling doors are the most widely used in the entrance and exit of factories, but due to the structure of the rolling door itself and other factors, its wind resistance will be limited, especially the super large and wide rolling doors. As the wind area increases, its wind resistance will decrease accordingly.

In the case of windy weather, the rolling shutter door is prone to deformation, and even damages the shutter door, affecting subsequent use
