The frozen oil is stirred and then impacts the buffering energy-absorbing elastic sheet, and the buffering energy-absorbing elastic sheet bulges to one side for absorbing energy, so that the blocking effect on the frozen oil is improved.

Preferably, the separation blade body is provided with a plurality of insertion holes, the cover plate is provided with a plurality of locking pins in one-to-one correspondence with the insertion holes, the end portions of the locking pins are uniformly provided with a plurality of locking heads, the locking pins are inserted into the insertion holes, and the locking heads abut against the surface of the separation blade body. The cover plate and the separation blade body are stably and reliably connected.

Preferably, the baffle body is provided with a circle of convex ring at the edge of the through hole of the baffle on the surface facing the cover plate, the cover plate is provided with an annular groove at the edge of the through hole of the cover plate on the surface facing the baffle body, the convex ring is installed in the groove in an adaptive manner, and the buffering energy-absorbing elastic sheet is tightly installed between the convex ring and the groove. The structure arrangement increases the sealing performance and reliability of the buffering energy-absorbing elastic sheet at the positions of the baffle through hole and the cover plate through hole, and is favorable for absorbing the energy of the buffering energy-absorbing elastic sheet to the refrigeration oil.

Compared with the prior art, the beneficial effects of the utility model are that: the oil stirring prevention lower bushing structure for the refrigeration compressor avoids the vortex phenomenon of the refrigeration oil at the bottom of the shell in the operation process of the refrigeration compressor, so that the noise and the influence on the internal balance of the compressor caused by the vortex are avoided.
