Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 5 , a medium-speed roller shutter door provided by the present invention includes a roller shutter door frame 1. A driving box 2 is fixedly connected to the upper end of the roller shutter door frame 1. A fixed rod 6 is fixedly connected to the inside of the driving box 2. A moving frame 8 is slidably connected to the outer surface of the damaged fixed rod 6. A spring 7 is sleeved on the outer surface of the fixed rod 6. A tooth groove 9 is fixedly connected to the upper surface of the moving frame 8. A blocking block 12 is fixedly connected to one side of the moving frame 8. A limiting wheel 13 is rotatably connected to the inside of the blocking block 12. A first motor 10 is fixedly connected to the inside of the driving box 2. A half gear 11 is fixedly connected to the output shaft of the first motor 10. After the roller shutter door body 4 is wound to the top, the spring 7 is used to push the moving frame 8 and the blocking block 12 to move below the roller shutter door body 4. The function of limiting the roller shutter door body 4 can be achieved through the provided blocking block 12, so as to achieve the function of fixing the roller shutter door body 4 after opening the door. When closing the door, the first motor 10 is started to drive the half gear 11 to rotate. When the half gear 11 rotates, it will pull the moving frame 8 and the blocking block 12 out from below the roller shutter door body 4, so as to achieve the function of closing the roller shutter door body 4.

[0025] Inside the driving box 2, a winding rod 14 is rotatably connected. On the outer surface of the winding rod 14, a first transmission wheel 15, a rolling shutter door body 4, and a clamping gear 19 are fixedly connected. Inside the driving box 2, a fixed plate 20 is fixedly connected. On the side surface of the fixed plate 20, a fixed clamping block 21 is fixedly connected. Inside the clamping gear 19, a movable clamping block 22 is rotatably connected. Inside the movable clamping block 22, a tension spring 23 is fixedly connected. When the rolling shutter door is suddenly damaged and the rolling shutter door body 4 rapidly descends, the clamping gear 19 is driven to rotate rapidly by the winding rod 14, so that the movable clamping block 22 is thrown out and clamped on one side of the fixed clamping block 21, thereby achieving the function of preventing the rolling shutter door body 4 from directly closing and falling to the ground. Inside the driving box 2, a second motor 16 is fixedly connected. On the output shaft of the second motor 16, a second transmission wheel 17 is fixedly connected. On the outer surface of the second transmission wheel 17, a transmission belt 18 is in transmission connection. After the second motor 16 drives the second transmission wheel 17 to rotate, the second transmission wheel 17 drives the winding rod 14 to rotate through the transmission belt 18, and the function of winding the rolling shutter door body 4 is achieved by the rotating winding rod 14. On the bottom side surface of the rolling shutter door body 4, a handle 5 is fixedly connected. On the side surface of the driving box 2, a protective shell 3 is fixedly connected. By setting the handle 5, the function of facilitating the pulling of the rolling shutter door body 4 can be achieved. At the same time, by setting the protective shell 3, the function of protecting the rolling shutter door body 4 can be achieved. The tooth groove 9 and the half gear 11 are in meshing cooperation. The blocking block 12 is slidably connected inside the rolling shutter door frame 1. When the toothed side of the half gear 11 rotates on the tooth groove 9, the half gear 11 will push the moving frame 8 and the blocking block 12 to move outwards. When the toothless side of the half gear 11 rotates on the tooth groove 9, under the action of the spring 7, the moving frame 8 and the blocking block 12 will be pushed inwards. The two ends of the tension spring 23 are connected to the clamping gear 19 and the movable clamping block 22. Four movable clamping blocks 22 are provided. By setting the tension spring 23, the function of pulling the movable clamping block 22 when the winding rod 14 rotates slowly can be achieved. The first transmission wheel 15 and the second transmission wheel 17 are in transmission connection through the transmission belt 18. After the second motor 16 drives the second transmission wheel 17 to rotate, then the second transmission wheel 17 drives the first transmission wheel 15 to rotate through the transmission belt 18.

[0026] Working principle:

[0027] After opening the rolling door body 4 and retracting the rolling door body 4 to the top, the moving frame 8 and the blocking block 12 are pushed by the spring 7 to move below the rolling door body 4. The blocking block 12 provided can limit the rolling door body 4, so as to fix the rolling door body 4 after opening the door. When closing the door, the first motor 10 is started to drive the half gear 11 to rotate. When the half gear 11 rotates, the moving frame 8 and the blocking block 12 are pulled out from below the rolling door body 4, so that the rolling door body 4 can be closed. When the rolling door is suddenly damaged and the rolling door body 4 drops rapidly, the winding rod 14 drives the clamping gear 19 to rotate rapidly, so as to throw out the movable clamping block 22 and clamp it on one side of the fixed clamping block 21, so as to prevent the rolling door body 4 from directly closing and falling to the ground.
