Chutes are formed on the other sides of the two columns. The rolling door box is installed at the tops of the two columns. A reel is arranged on the inner wall of the rolling door box. A curtain board is wound around the reel. Bearings are installed at both ends of the reel. The end of the reel passes through the bearing, and a wire winding wheel is installed at the passing end.

[0007] It further includes a pull rope. One end of the pull rope is wound around the wire winding wheel. The other end of the pull rope is connected with a first adjusting seat. One end of the first adjusting seat is slidably matched inside the chute. A tension spring is installed at the other end of the first adjusting seat. The bottom end of the tension spring is provided with a second adjusting seat. One end of the second adjusting seat is installed on one side of the outer wall of the column.

[0008] Preferably, the rolling door box is in the shape of a cuboid box with an open bottom end. Both ends of the reel are rotatably connected to both sides of the inner wall of the rolling door box. The curtain board is connected to the rolling door box through the reel.

[0009] Preferably, mounting holes are respectively formed at both ends of the outer wall of the rolling door box. Both ends of the reel respectively pass through and extend out of the mounting holes and are connected to two bearings. The number of wire winding wheels is two. One ends of the two wire winding wheels are respectively installed on the two bearings.

[0010] Preferably, the first adjusting seat includes a square block and a cylinder. One end of the pulling rope is connected to the square block, the winding wheel is connected to the first adjusting seat through the pulling rope, the size of one end of the cylinder matches the size of the inner wall of the sliding groove, and one end of the cylinder is abutted against the inner wall of the sliding groove.

[0011] Preferably, one end of the tension spring is connected to the first adjusting seat, the other end of the tension spring is connected to the second adjusting seat, the pulling rope is connected to the tension spring through the first adjusting seat, the number of tension springs is two, and the two second adjusting seats are respectively located on both sides of the outer wall of the column.

[0012] The utility model has the following beneficial effects:

[0013] Through the cooperation of the winding wheel, the pulling rope, the first adjusting seat, the tension spring, the second adjusting seat and the sliding groove, when the rolling shutter door rises, the tension spring is stretched to store elastic potential energy. The pulling force of the tension spring can help reduce the burden on the motor, making the rising of the rolling shutter door smoother. When the rolling shutter door descends, the elastic potential energy of the tension spring is gradually released, generating an upward pulling force, which plays a certain buffering role, making the descending speed of the rolling shutter door relatively stable, avoiding rapid falling. The pulling force of the tension spring also helps to maintain the stability of the rolling shutter door in the closed state and reduce the shaking of the door body. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-4, A protective rolling shutter door, comprising columns 1, guide grooves 2 and a rolling shutter box 3. The number of columns 1 is two. Guide grooves 2 are provided on the opposite surfaces of the two columns 1. Chute grooves 12 are provided on the other sides of the two columns 1. The rolling shutter box 3 is installed at the tops of the two columns 1. A reel 4 is provided on the inner wall of the rolling shutter box 3. A curtain panel 5 is wound around the reel 4. Installation holes are respectively provided at both ends of the outer wall of the rolling shutter box 3. Bearings 6 are installed at both ends of the reel 4. The end of the reel 4 passes through the bearing 6, and the passing end is installed with a wire winding wheel 7. The function of the wire winding wheel 7 is to control the lifting movement of the tension spring 10 through a pull rope 8. When the wire winding wheel 7 winds or unwinds, the pull rope 8 will drive the tension spring 10 to rise or fall along the chute groove 12. The rolling shutter box 3 is in the shape of a cuboid box with an open bottom end. The main function of the rolling shutter box 3 is to accommodate the reel 4 and the curtain panel 5 and protect them from the influence of the external environment. Motors, controllers, sensors, etc. are internally connected to the rolling shutter door to achieve automatic control and safety protection functions. Both ends of the reel 4 are respectively rotatably connected to both sides of the inner wall of the rolling shutter box 3. The curtain panel 5 is connected to the rolling shutter box 3 through the reel 4. Through the rotation of the reel 4, the curtain panel 5 can be wound or unfolded to achieve the opening and closing functions of the rolling shutter door;

[0021] One end of the pull rope 8 is wound around the wire winding wheel 7. The other end of the pull rope 8 is connected with a first adjustment seat 9. One end of the first adjustment seat 9 is slidably matched inside the chute groove 12. One end of the first adjustment seat 9 can flexibly slide inside the chute groove 12 to achieve smooth movement. A tension spring 10 is installed at the other end of the first adjustment seat 9. A second adjustment seat 11 is provided at the bottom end of the tension spring 10. One end of the second adjustment seat 11 is installed on one side of the outer wall of the column 1. One end of the tension spring 10 is connected to the first adjustment seat 9, and the other end of the tension spring 10 is connected to the second adjustment seat 11. The pull rope 8 is connected to the tension spring 10 through the first adjustment seat 9. The pull rope 8 can drive the first adjustment seat 9 to slide inside the chute groove 12 through the rotation of the wire winding wheel 7, thereby stretching or compressing the tension spring 10. The elastic characteristics of the tension spring 10 can provide a certain pulling force or buffering effect to achieve the rising, falling or maintaining stability of the rolling shutter door. The number of tension springs 10 is two. The two second adjustment seats 11 are respectively located on both sides of the outer wall of the column 1, forming a symmetrical layout, which helps to balance the force of the rolling shutter door and improve the smoothness and reliability of its operation.

[0022] When using this device, first connect an external power supply to the electrical equipment in this device, place this device at the designated working position, and through the cooperation of the wire winding wheel 7, the pulling rope 8, the first adjusting seat 9, the tension spring 10, the second adjusting seat 11 and the sliding groove 12. When the rolling shutter door rises, the tension spring 10 is stretched and stores elastic potential energy. The pulling force of the tension spring 10 can help reduce the burden on the motor, making the rising of the rolling shutter door smoother. When the shutter panel 5 of the rolling shutter door descends, the elastic potential energy of the tension spring 10 is gradually released, generating an upward pulling force, which plays a certain buffering role, making the descending speed of the rolling shutter door relatively stable and avoiding rapid falling. The pulling force of the tension spring 10 also helps to maintain the stability of the rolling shutter door in the closed state and reduce the shaking of the door body.
