Rounded corners are provided at the peripheral edges of the upper and lower ends of the support portion.

The depth of the damping groove is 4mm-6mm.

The damping cavity is a stepped cylindrical hole, and the stepped cylindrical hole includes an upper hole and a lower hole. The upper hole runs through the top and the mounting part of the foot pad body from top to bottom, and the diameter of the upper hole is smaller than the diameter of the lower hole.

The diameter of the lower hole is 1/2-2/3 of the outer diameter of the support part.

The height of the damping groove is 3 mm to 5 mm.

The foot pad body is a soft rubber pad.

The upper edge of the top is provided with a chamfer.

The cross-sectional shapes of the installation groove, the vibration-damping groove and the vibration-damping groove are all arc-shaped.

Compared with the prior art, the present invention has the following advantages:

The present invention provides a vibration-damping foot pad for a compressor. The installation groove between the top and the support part is used for installing the compressor. The vibration-damping groove on the outer wall of the support part can absorb and reduce the lateral vibration of the compressor. The vibration-damping chamber The vibration-damping groove at the bottom can absorb and reduce the vibration in the vertical direction of the compressor. Through this structural design, the stiffness of the vibration-damping foot pad is lower than that of the rubber material, which can effectively absorb and reduce the vibration of the compressor itself and the external transmission. vibration energy, thereby reducing the overall noise of the refrigerator. At the same time, the vibration-damping foot pad has a simple structure and is easy to install. The vibration-damping groove and the vibration-damping groove can reduce the amount of rubber materials and reduce the material cost.

detailed description

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

Referring to Fig. 2 to Fig. 4, this embodiment discloses a vibration damping foot pad for a refrigerator compressor, including a foot pad body, and the foot pad body can be a soft rubber pad with a Shore hardness of 40 to 45. The center of the foot pad body is provided with a vibration-damping chamber 3 penetrating up and down. The foot pad body includes a top 1, a mounting part and a supporting part 5 arranged in sequence from top to bottom, and the outer wall of the mounting part is recessed inward to form a compressor 70. The mounting groove 2, the outer diameter of the top 1 is smaller than the outer diameter of the supporting part 5. Rounded corners are provided at the circumferential edges of the upper and lower ends of the support portion 5 . An annular damping groove 4 is provided in the middle of the outer wall of the supporting part 5, and the depth of the damping groove 4 is 4mm-6mm. An annular damping groove 6 is also arranged on the inner wall of the damping chamber 3 in the center of the foot pad body. The height of the damping groove 6 is 3 mm to 5 mm. 6 is located below the damping groove 4.

Wherein, the cross-sectional shapes of the mounting groove 2, the vibration-damping groove 6 and the vibration-damping groove 4 are all arc-shaped. The upper edge of the top 1 is provided with a chamfer 7 to facilitate the installation of the vibration-damping foot pad 80 . The damping cavity 3 is a stepped cylindrical hole. The stepped cylindrical hole includes an upper hole and a lower hole. The upper hole runs through the top 1 and the mounting part of the foot pad body from top to bottom, and the diameter of the upper hole is smaller than the diameter of the lower hole. The diameter of the lower hole It is 1/2 to 2/3 of the outer diameter of the support part 5 .

Referring to Fig. 1, when installing, first place the damping pad 80 on the compressor base plate 30, and then connect the compressor 70 to the compressor through the bolt 40, nut 50, washer 10, spring washer 60, and bushing 20. The bottom plate 30 is fixed together, and the vibration generated by the compressor 70 during operation is transmitted to the compressor bottom plate 30 through the vibration-damping foot pad 80, and then transmitted to the refrigerator cabinet through the compressor bottom plate 30. The vibration-damping performance of the vibration-damping foot pad 80 is good or bad. It directly affects the noise of the refrigerator. In this embodiment, the vibration-damping groove 4 on the outer wall of the support part 5 can absorb and reduce the lateral vibration of the compressor 70, and the vibration-damping groove 6 at the bottom of the vibration-damping cavity 3 can absorb and reduce the vertical vibration of the compressor 70. The vibration in the direction can effectively absorb and reduce the vibration of the compressor 70 itself and the vibration energy transmitted to the outside, and has a good vibration and noise reduction effect, thereby reducing the overall noise of the refrigerator.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
