Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 , Figure 4 and Figure 8 The utility model provides an embodiment: a vibration-damping automobile pulley for an air-conditioning compressor, comprising a pulley main wheel 1, a connecting block 8 is provided at the front end of the pulley main wheel 1, a connecting block 2 9 is fixedly connected to the rear side of the pulley main wheel 1, and evenly distributed grooves 2 are provided on the outside of the pulley main wheel 1, and multiple grooves 2 are provided with springs 3 inside, and one end of multiple springs 3 is fixedly connected to the bottom of the inner wall of the multiple grooves 2, and the other end of multiple springs 3 is fixedly connected to rubber pads 2 5, and the outer wall of the pulley main wheel 1 is fixedly connected to evenly distributed rubber pads 4, and multiple grooves 2 are located between each rubber pad 4, and multiple rubber pads 25 are slidably connected between each rubber pad 4, and a connecting hole 6 is provided in the middle of the pulley main wheel 1 and the connecting block 29, and a connecting hole 27 is provided in the middle of the connecting block 8, and dustproof components are provided at the front and rear ends of the pulley main wheel 1, and the outer walls of multiple rubber pads 25 are fixedly connected with evenly distributed anti-slip strips 24.

[0036] The connecting hole 16 is connected to the outside, and the pulley main wheel 1 is driven by the outside to rotate as a whole. The belt contacts half of the rubber pad 25. When the pulley main wheel 1 starts to rotate, it drives the belt to rotate together. The part of the rubber pad 25 pressed by the belt will cause the spring 13 to sink downward into the groove 2. At the same time, part of the rubber pad 25 will also slide downward into the multiple rubber pads 14. When the pulley main wheel 1 rotates half a circle and the belt leaves this part of the rubber pad 25, the spring 13 will rebound upward and push the rubber pad 25 out of the multiple rubber pads 14. The multiple rubber pads 25 slide back and forth among the multiple rubber pads 14 and the elasticity of the spring 13 to achieve shock absorption of the belt to avoid shaking. When the belt contacts the rubber pad 25, the anti-slip strip 124 is used to prevent the belt from deviating. When the belt rotates through the pulley main wheel 1, the connecting block 29 and the connecting block 18 are used to limit the belt to prevent the belt from falling.

[0037] Reference Figure 1 and Figure 2 The dust-proof component includes a filter 10 and a weight-reducing hole 11. The filter 10 and the weight-reducing hole 11 are arranged in plurality. The plurality of filter screens 10 are arranged at the front and rear ends of the pulley main wheel 1. The plurality of weight-reducing holes 11 are respectively arranged at the front and rear sides of the connecting block 1 8 and the connecting block 2 9. The plurality of filter screens 10 are arranged in the middle of the plurality of weight-reducing holes 11. The plurality of weight-reducing holes 11 correspond to the plurality of filter screens 10. The opposite sides of the connecting block 1 8 and the connecting block 2 9 are fixedly connected with evenly distributed fan blades 13. The plurality of fan blades 13 are respectively fixedly connected to the inner walls of the two connecting rings 12.

[0038] When the pulley main wheel 1 starts to rotate, it will drive the connecting block 1 8 and the connecting block 2 9 to rotate together, and the multiple fan blades 13 will also rotate at the same time. When the front multiple fan blades 13 rotate, the air outside the front end will form wind and pass through the front multiple filter screens 10 to enter the multiple weight-reducing holes 11. The wind in the multiple weight-reducing holes 11 is blown out through the rear multiple filter screens 10, and the rear multiple fan blades 13 will also suck out the wind in the multiple weight-reducing holes 11 through the rear multiple filter screens 10 and discharge it, so as to dissipate the heat of the pulley main wheel 1. The multiple weight-reducing holes 11 opened in the pulley main wheel 1 can reduce its own weight, and the multiple filter screens 10 will also block external dust and other debris to avoid entering the multiple weight-reducing holes 11 that are difficult to clean.

[0039] Reference Figure 5 , Figure 6 and Figure 7The front end of the pulley main wheel 1 is fixedly connected with a snap-fit ​​block 22, and the rear side of the inner wall of the connecting hole 27 is provided with a snap-fit ​​groove 23, which is arranged at the rear side of the connecting block 18, and the snap-fit ​​block 22 is snap-fitted and connected inside the snap-fit ​​groove 23.

[0040] When the belt is installed, the pushing blocks 14 on both sides are slid toward opposite sides of each other, so that the two engaging rods 16 are separated from each other, and then the connecting block 8 is placed on the front end of the pulley main wheel 1, and the engaging block 22 is engaged in the engaging groove 23 and the connecting block 8 is pushed backward until the push ring 20 is against the limit ring 21, and then the two pushing blocks 14 are released, so that the springs 21 on both sides rebound together to bring the engaging rods 16 on both sides close to each other and engage them in the engaging grooves 18 on both sides to complete the fixation. When disassembling, the pushing blocks 14 on both sides are slid toward opposite sides of each other, so that the engaging rods 16 on both sides are separated from each other and leave the engaged engaging grooves 18 respectively. At this time, multiple springs 3 19 will rebound and push the connecting block 8 forward through the push ring 20, and then the connecting block 8 is pulled out from the front of the pulley main wheel 1 and leaves to complete the disassembly, which is convenient for replacing the belt, and the anti-slip strip 25 is used to facilitate the sliding of the two pushing blocks 14.

[0041] Reference Figure 1 - Figure 3 The inner diameter of the second connecting hole 7 is larger than that of the first connecting hole 6 , and the inner diameter of the limiting ring 21 is the same as that of the first connecting hole 6 .

[0042] The connection hole 1 6 is connected to the outside, the inner diameter of the connection hole 2 7 is larger than that of the connection hole 1 6 and cannot be connected to the outside, the inner diameter of the limiting ring 21 at the front end of the inner wall of the connection hole 2 7 is the same as that of the connection hole 1 6, and the limiting ring 21 can be connected to the outside like the connection hole 1 6.

[0043] Working principle: When the air-conditioning compressor is used with a vibration-damping automobile pulley, the push blocks 14 on both sides are slid to the opposite sides and away from each other, so that the engaging rods 16 on both sides are away from each other and leave the engaging engaging groove 18, and multiple springs 3 19 will rebound and push the connecting block 1 8 forward through the push ring 20, and then the connecting block 1 8 is pulled out from the front of the pulley main wheel 1 and removed to complete the disassembly, and the belt is put on the pulley main wheel 1 and contacts half of the rubber pad 2 5, Slide the push blocks 14 on both sides to the opposite sides to move the two engaging rods 16 away from each other, place the connecting block 18 on the front end of the pulley main wheel 1, engage the engaging block 22 into the engaging groove 23, and then push the connecting block 18 backward until the push ring 20 abuts against the limit ring 21 and squeezes the multiple springs 3 19, then release the two push blocks 14, and the springs 2 17 on both sides rebound together to push the engaging rods 16 on both sides closer to each other and engage into the engaging grooves 1 18 on both sides to complete. The belt is fixed to the outer surface through the connecting hole 16 and the limiting ring 21, and drives the pulley main wheel 1 to rotate. When the pulley main wheel 1 rotates, the belt will rotate on the pulley main wheel 1 and constantly change the part of the rubber pad 25 it contacts. When the part of the rubber pad 25 contacts the belt, the rubber pad 25 will slide down between the part of the rubber pad 14 through the belt and squeeze the multiple springs 13 downward. When the pulley main wheel 1 rotates half a circle, the belt and this part of the rubber pad 25 will be released from contact. The multiple springs 13 will push this part of the rubber pad 25 without pressure outward through the rebound of the spring 13, and the part of the rubber pad 25 will be higher than the rubber pad 14. The spring 13, rubber pad 14, and rubber pad 25 respectively surround the outer wall of the pulley main wheel 1. When the outer wall of the pulley main wheel 1 changes position, the belt will always contact the part of the rubber pad 25 and release the contact of the other part of the rubber pad 25, and the belt will be damped by the rebound of the multiple springs 13.
