[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] See also Figures 1 to 5The utility model provides a technical solution: a hidden guide rail steel composite fireproof rolling shutter door, comprising a storage bin 1, a guide rail 2 is fixedly connected to the bottom and corresponding sides of the storage bin 1, a first groove 5 is provided at the bottom of the storage bin 1, a rotating shaft 17 is rotatably connected inside the first groove 5, a rolling roller 6 is fixedly connected on the outside of the rotating shaft 17 and located inside the first groove 5, a second groove 9 is provided on one side of the guide rail 2, a screw rod 8 is rotatably connected inside the second groove 9, a first slider 10 is threadedly connected on the outside of the screw rod 8, a rolling shutter door 3 is fixedly connected to the outside of the rolling shutter door 3, a driving mechanism is provided on the outside of the rotating shaft 17 and the outside of the screw rod 8, and a dust brushing mechanism is provided inside the first groove 5 and on the corresponding sides of the rolling shutter door 3.
[0022] The driving mechanism includes two first bevel gears 18 and two second bevel gears 19. The two first bevel gears 18 are fixedly connected to the outside of the rotating shaft 17 and are located at both ends of the rolling roller 6. The second bevel gear 19 is fixedly connected to the outside of the two screw rods 8 and is located inside the storage bin 1. The first bevel gear 18 is meshed with the second bevel gear 19. The inside of the storage bin 1 is fixedly connected with a motor 7. The output end of the motor 7 is fixedly connected to the rotating shaft 17, which is conducive to driving the rolling roller 6 to roll up the rolling door 3, and the first slider 10 is connected to the outside of the screw rod 8. The second groove 9 slides inside and the motor 7 is started through the control panel 4 to drive the rotating shaft 17 to rotate. The rotating rotating shaft 17 drives the first bevel gear 18 to engage with the second bevel gear 19, so that the second bevel gear 19 drives the screw rod 8 to rotate inside the second groove 9, thereby driving the first slider 10 to slide inside the second groove 9. When the rotating shaft 17 rotates, it drives the rolling roller 6 to rotate to roll up the rolling door 3. The first slider 10 drives one end of the rolling door 3 to slide upward, and fixes one end of the rolling door 3 to prevent it from falling.
[0023] The dust brushing mechanism includes two third grooves 11, which are opened inside the storage bin 1 and located on both sides of the first groove 5. A sliding rod 12 is fixedly connected inside the third groove 11, and a second sliding block 14 is slidably connected to the outer side of the sliding rod 12. A spring 13 is provided on the outer side of the sliding rod 12 and on one side of the second sliding block 14. A connecting strip 15 is fixedly connected to one side of the two second sliding blocks 14 close to each other, and a brush 16 is fixedly connected to one side of the connecting strip 15. Because the rolling shutter door 3 is a concave-convex structure, when the convex surface of the rolling shutter door 3 is in contact with the connecting strip 15, the connecting strip 15 will be pushed backward, so that the second sliding block 14 is driven to slide on the outer side of the sliding rod 12 inside the third groove 11, thereby squeezing the spring 13. When encountering a concave surface, the compressed spring 13 rebounds and pushes the second sliding block 14, so that the connecting strip 15 drives the brush 16 back to its original position, which is beneficial to brush out the dust on the outer side of the rolling shutter door 3, thereby preventing dust from entering the interior of the guide rail and causing an impact.
[0024] The rolling shutter door 3 is composed of several rolling shutter pieces, which are easy to roll up. A steel outer layer is provided on the outside of the rolling shutter door 3, and an inorganic fiber composite inner layer is provided on the outside of the rolling shutter door 3 and inside the steel outer layer, which is beneficial to increase the fire resistance of the rolling shutter door 3. A control panel 4 is fixedly connected to one side of one of the guide rails 2, and the motor 7 is electrically connected to the control panel 4, which is beneficial to the operation of the staff and makes the operation more convenient.
[0025] In summary, when the hidden guide rail steel composite fireproof rolling shutter door is in use, the motor 7 is started through the control panel 4 to drive the rotating shaft 17 to rotate. The rotating rotating shaft 17 drives the first bevel gear 18 to mesh with the second bevel gear 19, so that the second bevel gear 19 drives the screw rod 8 to rotate inside the second groove 9, thereby driving the first slider 10 to slide inside the second groove 9. When the rotating shaft 17 rotates, it drives the rolling roller 6 to rotate, thereby rolling up the rolling shutter door 3, and drives one end of the rolling shutter door 3 to slide upward through the first slider 10. When the rolling shutter door 3 slides, the bristles 16 on one side of the connecting strip 15 brush off the dust on the surface of the rolling shutter door 3. Because the rolling shutter door 3 is a concave-convex structure, when the convex surface contacts the rolling shutter door 3, the connecting strip 15 will be pushed backward, so that the second slider 14 is driven to slide on the outside of the internal slide rod 12 of the third groove 11, thereby squeezing the spring 13. When encountering the concave surface, the compressed spring 13 rebounds and pushes the second slider 14, so that the connecting strip 15 drives the bristles 16 back to the original position.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
