[0002] Rolling shutter doors are made of multiple joints connected in series. In a fixed slide, the door rotates up and down with a reel above the door as the center. Rolling shutters are usually widely used in shops. Rolling shutter doors play the same role as walls in horizontal separation. Fireproof rolling shutter doors are a kind of fireproof and heat-insulating facilities suitable for large openings in buildings. They can prevent the spread of fire and ensure the safety of life and property. They are essential supporting products in modern buildings.

[0003] When rolling up the existing rolling shutter doors, the curtain pieces need to be collected into the door curtain box through the connecting groove. During the rolling process, since the curtain pieces will contact the inner wall of the connecting groove during the rising process, friction will be generated between the curtain pieces and the connecting groove, which will reduce the service life of the rolling shutter door. In addition, there is no limiting mechanism inside the rolling shutter door, and the phenomenon of over-retraction and over-release may easily occur during the process of rolling up and unrolling the rolling shutter door, resulting in damage to the rolling shutter door and affecting the service life of the rolling shutter door.
