[0002] A roller shutter door is a type of door with multiple articulated door panels linked together. It moves up and down within a fixed track, rotating around a central axis at the top of the door. Roller shutter doors mainly consist of the door body, drive unit, and control system. They are primarily used in situations such as shop entrances to isolate the interior from the outside world, factories that isolate space but not air, and main fire-resistant partition walls in logistics centers.

[0003] Roller shutters are generally divided into manual roller shutters and electric roller shutters. Electric roller shutters use a special motor to drive the central shaft of the roller shutter to rotate, thus opening and closing the roller shutter. When the rotation reaches the upper or lower limit set by the motor, it stops automatically. The electric roller shutter motor is the control and drive device of the roller shutter door, and it is a device that can realize automatic control of the roller shutter door.

[0004] When fire-resistant roller shutters are in use, the operation of the motor and the rolling and lowering of the shutters usually generate noise. To address this issue, we propose a sound insulation and noise reduction mechanism for fire-resistant roller shutters. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a fireproof rolling shutter door sound insulation and noise reduction mechanism, including a rolling shutter door assembly 1, a sound insulation component 3 installed on the rolling shutter door assembly 1, and a buffer component 2 provided below the rolling shutter door assembly 1;

[0028] The buffer assembly 2 includes a buffer plate 21, a mounting plate 22, and a buffer part 23. The buffer plate 21 is located below the roller shutter door assembly 1, the mounting plate 22 is located directly below the buffer plate 21 and is mounted on a step, and the buffer part 23 is located between the buffer plate 21 and the mounting plate 22.

[0029] The buffer part 23 includes a base 231, a spring 232, a damping device 233 and an upper plate 234. The base 231 and the upper plate 234 are respectively mounted on the mounting plate 22 and the buffer plate 21. The spring 232 and the damping device 233 are both mounted between the base 231 and the upper plate 234, and the spring 232 is sleeved on the surface of the damping device 233.

[0030] Specifically, when using the roller shutter assembly 1, when the fireproof component 11 is lowered, the buffer assembly 2 can buffer the fireproof component 11 and the fixing component 13, thereby preventing the fixing component 13 from directly hitting the ground and reducing the noise generated when lowering the fireproof component 11. When buffering the fixing component 13, the fixed mounting plate 22 can be used. When the fixing component 13 descends, it will drive the buffer plate 21 to move downward, thereby compressing the spring 232 and the damping device 233. At this time, the impact force when the fixing component 13 descends can be buffered, thereby preventing the fixing component 13 from directly hitting the ground.

[0031] In this embodiment, the buffer assembly 2 further includes a connecting part 24, which is disposed on the mounting plate 22 and connected to the step. The connecting part 24 includes a lead screw 241, a ratchet 242, and a ratchet tooth 243. Connecting holes are provided on the surface of the mounting plate 22 and the step. The lead screw 241 is disposed in the connecting hole, the ratchet 242 is disposed on the mounting plate 22 and is threadedly connected to the lead screw 241, and the ratchet tooth 243 is disposed on the mounting plate 22 and is engaged with the ratchet 242.

[0032] Specifically, during use, it is necessary to stably connect the mounting plate 22 to the ground. This can be achieved by setting a connecting part 24 on the mounting plate 22, inserting the lead screw 241 into the connecting hole, and threading it to the ratchet 242. The ratchet 243 engages the ratchet 242, thus preventing the lead screw 241 from rotating in the opposite direction, thereby ensuring that the mounting plate 22 can be stably set up.

[0033] In this embodiment, the roller shutter door assembly 1 includes a limiting member 12, a mounting box 14, a guide wheel 15, and a winding wheel 16. The limiting member 12 is installed on the door frame, the mounting box 14 is installed on the limiting member 12, and the guide wheel 15 and the winding wheel 16 are both disposed inside the mounting box 14. The roller shutter door assembly 1 also includes a fireproof member 11 and a fixing member 13. The fireproof member 11 is slidably disposed inside the limiting member 12 and is connected to the winding wheel 16. The fixing member 13 is disposed at the end of the fireproof member 11.

[0034] Specifically, during fire prevention operations, the fireproof component 11 and the fixing component 13 can be lowered by rotating the take-up wheel 16. When the fireproof component 11 is being rolled up, the take-up wheel 16 can be rotated in the opposite direction. During the rolling process, the guide wheel 15 can be used for guidance. During both rolling and lowering, the mounting box 14 can provide initial sound insulation for the internal components such as the motor.

[0035] In this embodiment, the sound insulation component 3 includes a sound insulation cover 31, a connecting rod 32, a moving block 33, a B-screw 34, and a rotating shaft 35. The rotating shaft 35 is rotatably mounted on the mounting box 14, the connecting rod 32 is mounted on the rotating shaft 35, and a moving groove is formed on the surface of the connecting rod 32. The moving block 33 and the B-screw 34 are both mounted in the moving groove, and the moving block 33 is threaded onto the B-screw 34. The sound insulation cover 31 is connected to the moving block 33.

[0036] Specifically, when operating the roller shutter door assembly 1, in order to further improve sound insulation, a sound insulation component 3 can be installed on the mounting box 14. Further sound insulation can be achieved through the sound insulation cover 31. When installing the sound insulation cover 31, the B screw 34 can be rotated to drive the moving block 33 to move, thereby driving the sound insulation cover 31 to move. At this time, the rotating shaft 35 can be rotated to drive the connecting rod 32 to rotate, and the height position of the sound insulation cover 31 can be adjusted.

[0037] In this embodiment, the sound insulation component 3 also includes meshing teeth 36 and gears 37. A rotating shaft 35 is provided on the surface of the connecting rod 32, and the gears 37 are disposed on the mounting box 14. The meshing teeth 36 and gears 37 mesh.

[0038] Specifically, in use, the connecting rod 32 can be rotated by rotating the gear 37, which in turn can place the soundproof cover 31 in front of the mounting box 14. By rotating the lead screw 34, the soundproof cover 31 can be stably fitted with the mounting box 14, thereby improving the sound insulation effect.

[0039] In this embodiment, two sound insulation components 3 are provided, and the two sound insulation components 3 are symmetrically arranged, with a drive shaft 4 provided between the two meshing teeth 36.

[0040] Specifically, in order to enable the two gears 37 to be driven simultaneously during use, the two gears 37 can be connected by a drive shaft 4, and the drive shaft 4 is set through the mounting box 14.

[0041] The working principle and usage process of this utility model are as follows: When using the roller shutter assembly 1 for fire prevention operations, the fireproof component 11 can be lowered by running the roller shutter assembly 1. In order to avoid generating a lot of noise when lowering, a sound insulation component 3 can be installed on the mounting box 14. The mounting box 14 and the sound insulation component 3 can insulate the noise generated during operation. When the fireproof component 11 and the fixing component 13 are lowered, the fixing component 13 can be buffered by the buffer component 2 to avoid the fixing component 13 directly hitting the ground and generating a lot of noise.

[0042] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
