The invention discloses a hard fast roller shutter door which comprises a roller shutter door body. A traction belt outer clamping sheet is arranged at the top end of one side of the roller shutter door body. The bottom end of the traction belt outer clamping sheet is fixedly connected with a door plate synchronous belt. Bolts are fixedly connected to the two sides of the traction belt outer clamping sheet correspondingly. The upper ends of the bolts are connected with anti-loosening nuts correspondingly. The traction belt outer clamping sheet is internally connected with a traction belt innerclamping sheet. A driving motor is arranged on one side of the upper end of the roller shutter door body. The output end of one side of the driving motor is connected with a movable rod. The other end of the movable rod is connected with the door plate synchronous belt. One side of the roller shutter door body is connected with sound-absorbing cotton. One side of the roller shutter door body andone side of the door plate synchronous belt are each fixedly connected with fixing clamping plates. An infrared sensor is arranged on the door plate synchronous belt. The bottom of the outer side of the roller shutter door body is connected with a rubber pad. A photoelectric ranging sensor is arranged on the bottom side of the roller shutter door body. The hard fast roller shutter door is intelligent, fast and convenient to use and has the high sealing property, high heat preservation property, high anti-wind and anti-theft properties, low noise and fast and stable operation property, and thecost is constantly reduced, and the work efficiency is improved.
