The existing shock-absorbing pad structure is a whole rubber block, which is fixed between the frame and the compressor foot by bolts. During the vibration process, the compressor foot moves up and down relative to the frame. When the compressor foot squeezes the rubber block and moves upward, the compressor foot hits the limit bolt, limiting the vibration amplitude of the upward movement, and the vibration noise generated is large.

DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-2 This application is described in further detail.
[0028] The embodiment of the present application discloses a compressor shock absorber.
[0029] A compressor shock absorber, referring to Figure 1 and Figure 2, including a protective cover 1, the protective cover 1 is cylindrical, one end of the protective cover 1 is open, the bottom of the protective cover 1 is coaxially provided with a limiting groove 16, a shock-absorbing pad 2 is inserted in the limiting groove 16, the material of the shock-absorbing pad 2 is rubber, the shock-absorbing pad 2 is provided with an upper ball joint seat 3 on the side close to the opening of the protective cover 1, the upper ball joint seat 3 is also inserted in the limiting groove 16, the opening of the protective cover 1 is threadedly connected with a bottom plate 4, the bottom plate 4 is provided with threads on its periphery, a shock-absorbing pad 5 is provided on the side of the bottom plate 4 close to the upper ball joint seat 3, and the shock-absorbing pad 5 is located at the protective cover Inside the cover 1, the shock-absorbing pad 5 is also made of rubber. A lower ball joint seat 6 is installed on the side of the shock-absorbing pad 5 close to the upper ball joint seat 3. A joint ball 7 is clamped between the upper ball joint seat 3 and the lower ball joint seat 6. The protective cover 1 is provided with a through hole 8 at the bottom of the limiting groove 16. The through hole 8 penetrates the shock-absorbing pad layer 2 and the upper ball joint seat 3 at the same time. The side wall of the joint ball 7 is integrally connected with a connecting screw 9. The end of the connecting screw 9 away from the joint ball 7 passes through the through hole 8 and extends out of the protective cover 1. The end of the connecting screw 9 away from the joint ball 7 is threadedly connected with a height adjustment nut 10 and a locking nut 11.
[0030] In order to absorb vibrations in more directions, it is necessary to give the connecting screw 9 space for rotation and adjustment. In this embodiment, the radius of the perforation 8 is 0.5-3mm larger than the radius of the connecting screw 9. The connecting screw 9 can be rotated at a certain angle relative to the protective cover 1, thereby absorbing vibrations from more directions and enhancing the shock absorption effect.
[0031] Reference Figure 1 and Figure 2 A connecting screw hole 14 for fixing the bottom plate 4 to the frame is formed through the center of the side of the bottom plate 4 away from the shock-absorbing pad 5, and a receiving hole 15 is formed at a position corresponding to the connecting screw hole 14 on the side of the shock-absorbing pad 5 close to the bottom plate 4. The receiving hole 15 is a blind hole, and the radius of the receiving hole 15 is larger than the connecting screw hole 14, and the receiving hole 15 is coaxial with the connecting screw hole 14.
[0032] Because the bottom plate 4 is threadedly connected to the opening of the protective cover 1, in order to realize the disassembly and assembly of the bottom plate 4, the outer wall of the protective cover 1 is provided with a positioning groove 12 for easy holding, the positioning groove 12 is close to the opening of the protective cover 1, and multiple positioning grooves 12 are distributed in a circumferential array on the outer wall of the protective cover 1. The side of the bottom plate 4 away from the shock-absorbing pad 5 is penetrated with a screwing groove 13 for easy screwing of the bottom plate 4 by a tool. The screwing groove 13 is a round hole, and there are two screwing grooves 13, which are respectively located on both sides of the connecting screw hole 14. When in use, the opening of the protective cover 1 is clamped with a tool. During the screwing process, part of the clamping tool is inserted into the positioning groove 12 to prevent the protective cover 1 from rotating with the bottom plate 4 when the bottom plate 4 is screwed. Then another tool is inserted into the screwing groove 13, and the two tools are rotated relative to each other, so as to disassemble and assemble the bottom plate 4.
[0033] The installation method of a compressor shock absorber according to an embodiment of the present application is as follows: first, the base plate 4 is locked and fixed to the frame by means of bolts engaging with the connecting screw holes 14; the locking nut 11 is unscrewed, the end of the connecting screw 9 is passed through the hole on the compressor foot, the height adjustment nut 10 is screwed, the compressor is adjusted to a horizontal state and at a desired height, and finally the locking nut 11 is screwed onto the connecting screw 9 to lock the compressor foot.
[0034] The beneficial effects of a compressor shock absorber according to an embodiment of the present application are as follows:
[0035] 1. Reduce vibration noise; connect the screw rod 9 and the hinge ball 7 to fix the compressor. During the vibration process, the upper and lower sides of the hinge ball 7 are respectively provided with a shock-absorbing cushion layer 2 and a shock-absorbing cushion block 5. The hinge ball 7 drives the upper ball hinge seat 3 and the lower ball hinge seat 6 to move up and down, squeezing the shock-absorbing cushion layer 2 or the shock-absorbing cushion block 5 on both sides, thereby greatly reducing the noise generated by the vibration;
[0036] 2. Reduce the vibration amplitude of the compressor; the hinge ball 7 transmits the force to the lower ball hinge seat 6, and the lower ball hinge seat 6 squeezes the shock-absorbing pad 5. In this process, the force-bearing surface of the squeeze is increased. Under the same vibration force, the amplitude is greatly reduced;
[0037] 3. The shock absorption angle is more diversified and the shock absorption effect is better; compared with the prior art which can only perform shock absorption in the vertical direction, the hinge ball 7 and the connecting screw 9 of the present application can rotate within a certain angle, thereby absorbing more vibrations from the compressor.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
