Description

TECHNICAL FIELD

[0002] A roller shutter door is a door piece with multiple joints in series, which is connected in a fixed slide and rotates up and down around a roller on the top of the door. The roller shutter door is widely used in stores. The roller shutter door, like a wall, plays a role in horizontal separation, which is composed of a curtain plate, a seat plate, a guide rail, a support, a roller shaft, a box, a control box, a roller door machine, a limiter, a lintel, a manual speed release switch device, a button switch and a safety device, and is usually installed in a position where a wall is not convenient to separate.

[0003] The roller shutter door is suitable for public places or residences such as commercial facades, garages, shopping malls, hospitals, factories and mines, etc. Especially, it is convenient and fast to open in places where the door opening is large and it is inconvenient to install a ground door body. For example, it is used for garage doors, shopping mall fireproof roller shutter doors, aircraft hangar doors, etc. It generally plays a good role in space separation, theft prevention and fire compartmentation.

[0004] However, due to the limitations of the structure and material of the roller shutter door, the wind resistance of the roller shutter door is weak, especially for the roller shutter door with large height and width. The hidden door frame of the roller shutter door is not enough to provide sufficient wind resistance for the roller shutter door. When the wind is too strong, the roller shutter door will be bent and deformed, and even damaged. Therefore, how to solve the problem of wind resistance of the roller shutter door is a technical problem that needs to be solved in the field. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the above technical problems in the prior art, and provides a roller shutter door with a movable wind-resistant structure. Due to the wind pressure on the roller shutter door, the curtain plate is bent inward and deformed. Since the transmission box is generally arranged on the inner side of the curtain plate, a sliding rail is arranged at the bottom of the curtain plate, the wind-resistant mechanism is slidably connected to the sliding rail through a sliding block, and a fixing member is arranged at the bottom of the wind-resistant mechanism. When the roller shutter door is used normally, the wind-resistant mechanism is controlled to move to the two sides of the door frame along the direction of the sliding rail, and the bottom of the wind-resistant mechanism is fixed to the ground through the fixing member, so that the normal use of the roller shutter door is not affected. When the wind-resistant mechanism needs to be used in strong wind, the fixing member is loosened from the ground, the wind-resistant mechanism is controlled to move to the inner side of the curtain plate, and the fixing member is fixed to the ground. When the curtain plate is bent inward due to wind pressure, the wind-resistant mechanism limits the inner side of the curtain plate and resists the bending deformation of the curtain plate caused by wind pressure, thereby greatly improving the wind resistance of the roller shutter door.
