The outer annular groove 101 is disposed on the outer wall of the vibration damping pad body 110, and the outer annular groove 101 is adapted to cooperate with the support plate of the compressor casing. The support plate of the compressor casing can be clamped in the outer annular groove 101 , and then the compressor can be supported on the vibration-damping pad 100 through the support plate of the compressor.

The first inner annular groove 103 and the second inner annular groove 105 are sequentially disposed on the inner peripheral wall of the mounting hole 107 from top to bottom and extend outward. That is to say, the first inner annular groove 103 is arranged above the second inner annular groove 105, the first inner annular groove 103 is formed on the inner peripheral wall of the mounting hole 107 and extends outward, the second inner annular groove 105 Formed on the inner peripheral wall of the mounting hole 107 and extending outward, the first inner annular groove 103 and the second inner annular groove 105 are spaced apart.

The inner peripheral wall of the mounting hole 107 of the vibration damping pad 100 in the embodiment of the utility model is provided with a first inner annular groove 103 and a second inner annular groove 105 spaced apart, so that compared with the traditional vibration damping pad, this The vibration damping pad 100 of the utility model embodiment has a better vibration damping effect, can well avoid the resonance frequency of the compressor and the bottom plate, reduce the vibration transmission from the compressor to the bottom plate, and further prevent the compressor and the refrigerator box from being damaged due to resonance. Creates a humming noise that can significantly reduce the noise of the entire refrigerator system.

After the compressor is powered on, the motor part in the compressor housing starts to rotate, and the motor part drives the compression mechanism part through the operation, and the connecting rod of the compression mechanism part drives the piston to perform reciprocating linear motion through reciprocating rotation, and sucks the refrigerant. A series of processes of compression and discharge.

During the reciprocating process, the motor part of the compressor and the compression mechanism part will vibrate, and the vibration will be transmitted to the compression shell through the internal base and pipelines, and the transmitted vibration will pass through the support plate, and finally be absorbed and attenuated by the vibration-damping pad 100 .

Because the vibration damping pad 100 of the embodiment of the utility model has excellent vibration damping effect, the vibration generated during the operation of the compressor and the noise caused by vibration transmission can be effectively absorbed and attenuated, effectively slowing down the vibration between the compressor and the The resonance of the refrigerator box prevents the compressor from vibrating again in the system and further improves the reliability of the compressor.

According to the vibration damping pad 100 for the compressor according to the embodiment of the present invention, by setting the first inner annular groove 103 and the second inner annular groove 105 spaced apart on the mounting hole 107 in the vibration damping pad body 110, The vibration-damping pad 100 can have a better vibration-damping effect, further reducing the vibration and noise of the compressor, and the noise generated between the compressor shell and the bottom plate due to vibration is also greatly reduced.
