After the fastener 5 passes through the first through hole 427 and the second through hole 428 and is connected to the fixing portion 6 to lock the elastic pad assembly 4 on the chassis 2, a certain distance is maintained between the second through hole 428 and the fastener 5. When the compressor 1 is working, the radial movement of the elastic pad assembly 4 is increased, and the free vibration of the elastic pad assembly 4 in the up-down and horizontal directions is ensured, so as to achieve the maximum attenuation of the vibration energy of the compressor 1 in the up-down direction and the torsional tangential direction, and the vibration reduction effect is good.

[0034] Preferably, the fastener 5 is a positioning bolt; the fixing portion 6 is a positioning nut; the positioning bolt and the positioning nut are matched and connected to lock the elastic foot pad assembly 4 on the chassis 2.

Moreover, the fastener 5 and the chassis 2 are positioned and fixed by riveting or spot welding.

[0035] Embodiment 1:

[0036] In this embodiment, the upper end of the elastic foot pad assembly 4 is provided with a second groove 422; the compressor base 3 is sleeved in the second groove 422; the elastic foot pad assembly 4 includes a fixed foot pad 41, a supporting foot pad 42 and an elastic member 43; the first through hole 427 and the second through hole 428 are both located on the supporting foot pad 42; the fixed foot pad 41 is located below the supporting foot pad 42; the elastic member 43 is provided on the supporting foot pad 42; the upper end of the supporting foot pad 42 has the second groove 422.

[0037] The compressor vibration reduction installation structure is provided with a second groove 422 at the upper end of the elastic pad assembly 4, so that the compressor foot 3 is sleeved in the second groove 422. Specifically, the compressor foot 3 is sleeved on the second groove 422 at the upper end of the supporting pad 42, thereby ensuring the installation reliability of the compressor foot 3, and the structure is simpler, the assembly is more convenient, and the assembly efficiency is high. At the same time, the elastic pad assembly 4 is combined with the fixed pad 41, the supporting pad 42 and the elastic member 43, and the fastener 5 passes through the first through hole 427 of the fixed pad 41 and the second through hole 428 of the supporting pad 42, and is connected to the fixing part 6 to lock the elastic pad assembly 4 on the chassis 2, wherein the aperture of the first through hole 427 is equivalent to the diameter of the fastener 5, and after assembly, the elastic pad assembly 4 is prevented from radial movement, which plays a good positioning role. The second through hole 428 has a larger diameter and maintains a certain distance from the fastener 5. When the compressor 1 is working, the radial movement of the elastic foot pad assembly 4 is increased, ensuring the free vibration of the elastic foot pad assembly 4 in the up and down and horizontal directions, achieving the maximum attenuation of the vibration energy of the compressor 1 in the up and down directions and the torsional tangential directions, and having a good vibration reduction effect.

[0038] The elastic member 43 is a spring; the fixed foot pad 41 and the supporting foot pad 42 are rubber foot pads. The rubber foot pad is made of rubber material. The rubber material is divided into EPDM rubber, nitrile rubber, chloroprene rubber, etc. Of course, other elastomers similar to rubber materials can be used, such as TPE thermoplastic elastomer.

[0039] In order to improve the assembly efficiency of the elastic foot pad assembly 4, the upper end of the supporting foot pad 42 also has a fourth boss 425 located at the lower end of the second groove 422; the elastic member 43 is sleeved on the supporting foot pad 42; the lower end of the supporting foot pad 42 is engaged with the fixed foot pad 41 to lock the elastic member 43 between the fourth boss 425 and the fixed foot pad 41. By engaging the lower end of the supporting foot pad 42 with the fixed foot pad 41, it is convenient to lock the elastic member 43 between the fourth boss 425 and the upper end surface of the fixed foot pad 41, so as to realize the rapid assembly of the elastic foot pad assembly 4, with reliable structure and convenient installation.

[0040] Specifically, the fixed foot pad 41 includes a foot pad body 411 and a first boss 413. The foot pad body 411 is located below the elastic member 43; the foot pad body 411 has a through opening 412 extending from top to bottom; the first boss 413 is provided at the upper end of the foot pad body 411 and is located in the through opening 412; the lower end of the supporting foot pad 42 has a first groove 421 that is engaged with the first boss 413. In this embodiment, the fixed foot pad 41 is cylindrical, and the fixed foot pad 41 has a through opening 412 extending from top to bottom, so that the fixed foot pad 41 is annular. The first boss 413 is provided at the upper end of the fixed foot pad 41, and is engaged with the first groove 421 at the lower end of the supporting foot pad 42, so that the elastic foot pad assembly 4 can be quickly assembled, with a reliable structure and convenient installation.

[0041] In order to prevent the elastic member 43 from popping out when working and increase the reliability of the elastic pad assembly 4 when working; the upper end of the support pad 42 has a second boss 423 located at the lower end of the fourth boss 425 and in contact with the inner diameter of the elastic member 43; the lower end of the support pad 42 has a third boss 424 located at the upper end of the first groove 421 and in contact with the inner diameter of the elastic member 43; the support pad 42 also has an axial surface 426 located between the second boss 423 and the third boss 424. By setting the second boss 423 and the third boss 424 in contact with the spiral inner diameter of the elastic member 43, the elastic member 43 is prevented from popping out when working, and the reliability of the elastic pad assembly 4 is increased when working. At the same time, under the premise of ensuring the reliable installation of the compressor base 3, the elastic member 43 is sleeved on the outer side of the support pad 42, and a sufficient distance is left between the elastic member 43 and the axial surface 426, so as to ensure the free vibration of the spring in the vertical and horizontal directions, and realize the maximum attenuation of the vibration energy of the compressor 1 in the vertical direction and the torsional tangential direction.

[0042] The outer peripheral side of the top of the support pad 42, the outer peripheral side of the bottom of the support pad 42, and the inner peripheral side of the top of the first boss 413 are all chamfered. By setting the chamfer, the compressor base 3 is accelerated to slide quickly into the second groove 422 along the chamfer, the structure is simple, the operation is convenient, and the assembly efficiency is improved. Similarly, the first boss 413 and the first groove 421 are conveniently matched and clamped, the structure is simple, the operation is convenient, and the assembly efficiency is improved.

The elastic member 43 is preferably a spring. In order to improve the assembly efficiency and have more engineering application value, the elastic pad assembly 4 is now improved, that is, the fixed pad 41, the supporting pad 42 and the elastic member 43 embedded in the supporting pad 42 are integrally injection molded, which helps to save the cost caused by manual pre-installation; improve the assembly efficiency of the compressor vibration reduction installation structure; make the elastic pad assembly 4 look like a material (rubber) from the outside, and more beautiful.
