[0023] Specifically, the shock-absorbing and noise-reducing component 3 includes a fixing device 31, a fixing rod 32, a damping slider 33, a support rod 34, a buffer spring 35, a mounting plate 36, an assembling plate 37 and a connecting plate 38, wherein a mounting plate 36 is arranged on one side surface of the mounting frame 2, a fixing rod 32 is symmetrically arranged inside the mounting plate 36, a buffer spring 35 is sleeved on the surface of the fixing rod 32, a damping slider 33 is arranged on one end of the buffer spring 35, a support rod 34 is arranged on one side of the damping slider 33, a connecting plate 38 is arranged on one end of the support rod 34, an assembling plate 37 is arranged on one side of the connecting plate 38, and a fixing device 31 is symmetrically arranged on both ends of the assembling plate 37.

[0024] By adopting the above technical solution, the operation of the ventilation fan 5 will affect the environmental quality due to the noise generated. At this time, a mounting plate 36 can be installed on one side of the mounting frame 2. When the ventilation fan 5 vibrates during operation, the connecting plate 38 on one side of the assembly plate 37 pushes the support rod 34 to move. At this time, the damping slider 33 slides along the surface of the fixing rod 32 and causes the buffer spring 35 to be compressed, thereby ensuring that the vibration generated by the fixing frame 4 on one side of the mounting frame 2 and the ventilation fan 5 inside it can be buffered, thereby achieving the effect of reducing noise.

[0025] Specifically, the support rod 34 is connected between the damping slider 33 and the connecting plate 38 through a pin shaft, and the connecting plate 38 and the assembling plate 37 are an integrated structure.

[0026] By adopting the above technical solution, it is ensured that the support rod 34 can normally drive the damping slider 33 and the connecting plate 38 to move when in use, and the connecting plate 38 and the assembling plate 37 are an integrated structure to ensure the strength of the equipment.

At this time, the compressed limit spring 314 is reset to push the connecting frame 313 to rise along the surface of the guide rod 312, thereby causing the abutment seat 311 to move upward and abut against the inside of the installation position for fixation. At the same time, the staff can also install and fix the assembly plate 37 through the installation hole inside the abutment seat 311 with bolts, thereby improving the applicability of the equipment.

[0029] Specifically, the positioning handle 315 is configured to be L-shaped, and the positioning handle 315 is installed inside the connecting frame 313 via a movable shaft, and a slot is provided inside the assembling plate 37 corresponding to the positioning handle 315 .

[0030] By adopting the above technical solution, it is ensured that the positioning handle 315 can be rotated inside the connecting frame 313, and can be inserted into the card slot inside the assembly plate 37 for positioning after being moved downward.

[0031] When the embodiment is in use, the ventilation fan 5 will affect the environmental quality due to the noise it generates when it is working. At this time, a mounting plate 36 can be installed on one side of the mounting frame 2. When the ventilation fan 5 vibrates during operation, the connecting plate 38 on one side of the assembly plate 37 pushes the support rod 34 to move. At this time, the damping slider 33 slides along the surface of the fixing rod 32 and compresses the buffer spring 35, ensuring that the vibration generated by the fixing frame 4 on one side of the mounting frame 2 and the ventilation fan 5 therein can be buffered, thereby achieving the effect of reducing noise.

[0032] When the assembly plate 37 needs to be installed and used, the assembly plate 37 can be aligned with the pre-installation position, and then the positioning handle 315 can be rotated along the movable axis to pull it out from the slot. At this time, the compressed limit spring 314 is reset to push the connecting frame 313 to rise along the surface of the guide rod 312, thereby causing the abutment seat 311 to move upward and abut against the inside of the installation position for fixation. At the same time, the staff can also install and fix the assembly plate 37 through the installation hole inside the abutment seat 311 with bolts, thereby improving the applicability of the equipment.

At the same time, the pressing block 62 abuts against the upper end of the lotion pump 65 to press it down. The lotion pump 65 squeezes the lubricating oil inside the oil storage tank 61 and sprays it to the oil dripping pipe 66 to fall. At this time, the lubricating oil drips along the inside of the oil dripping pipe 66 and lubricates the inside of the ventilation fan 5, thereby ensuring the smooth operation of the ventilation fan 5, preventing abnormal noises, and improving the noise reduction quality.

[0036] The emulsion pump 65 in the utility model is an existing disclosed technology, and the selected model is MPS-5001.

[0037] The structure and use principle of the sound-absorbing and noise-reducing folding plate 1 and the ventilation fan 5 in the utility model have been disclosed in a noise reduction structure of a ventilation device disclosed in Chinese patent application No. 202322052729.0.

[0038] Working principle and use process of the utility model: When the utility model is in use, the ventilation fan 5 will affect the environmental quality due to the noise it generates when working. At this time, a mounting plate 36 can be installed on one side of the mounting frame 2. When the ventilation fan 5 vibrates during operation, the connecting plate 38 on one side of the assembly plate 37 pushes the support rod 34 to move. At this time, the damping slider 33 slides along the surface of the fixing rod 32 and compresses the buffer spring 35, ensuring that the vibration generated by the fixing frame 4 on one side of the mounting frame 2 and the ventilation fan 5 therein can be buffered, thereby achieving the effect of reducing noise.

[0039] When the assembly plate 37 needs to be installed and used, the assembly plate 37 can be aligned with the pre-installed position, and then the positioning handle 315 can be rotated along the movable axis to pull it out from the slot. At this time, the compressed limit spring 314 is reset to push the connecting frame 313 to rise along the surface of the guide rod 312, so that the abutment seat 311 moves upward to abut against the inside of the installation position for fixation. At the same time, the staff can also install and fix the assembly plate 37 through the mounting hole inside the abutment seat 311 through the bolt, thereby improving the applicability of the equipment;

[0040] When the ventilation fan 5 is insufficiently lubricated or makes abnormal noises after long-term use and needs to be lubricated inside, the rotating block 64 is rotated along the fixed shaft 63 to rotate the pressing block 62. At the same time, the pressing block 62 abuts against the upper end of the lotion pump 65 to press it down. The lotion pump 65 squeezes the lubricating oil inside the oil storage tank 61 and sprays it to the oil dripping pipe 66 to fall. At this time, the lubricating oil drips along the inside of the oil dripping pipe 66 and lubricates the inside of the ventilation fan 5, thereby ensuring the smooth operation of the ventilation fan 5, preventing abnormal noises, and improving the noise reduction quality.
