Among the above-mentioned technical scheme, through increasing the damping ring between the toe board and the rubber pad of compressor, when the compressor operation, the vibration that comes from the compressor body passes through the toe board and transmits the damping ring, then transmits the rubber pad pressure-bearing part through the damping ring for the transmission of vibration has certain hysteresis quality, can effectively reduce system vibration value. Because the center of the rubber pad is easy to deform, the part with the maximum central deformation and other parts can jointly form a cantilever beam structure through the vibration reduction ring, and the buffering capacity can be further enhanced. In frequency conversion products or high-rotation-speed products, instantaneous vibration sudden change can be brought by the change of the rotation speed, and the vibration reduction capability of the rubber pad can be gradually attenuated under the condition of long-time high rotation speed.
