As a further aspect of the present invention: the flexible shock pad is assembled with the machine core through a buckle fixed on the machine core, and the buckle is a fixing buckle matched with the flexible shock pad in shape.

As a further aspect of the present invention: the flexible shock pad is made of rubber or plastic materials.

As a further aspect of the present invention: the limiting supports are at least provided with two groups and are welded and fixed on the inner wall of the lower shell, and the springs and the spring supports are at least provided with four groups.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses in, the compressor is keeping flat or three faces of core flexible snubber block and spacing support inner wall, baffle inner wall and the inferior valve inner wall of pressure spring bearing in certain inclination all have certain unsettled clearance, when exceeding certain inclination or receiving the exogenic action, flexible snubber block on the core will be direct with three faces of spacing support inner wall, baffle inner wall or inferior valve inner wall direct contact collision each other, play upper and lower, left and right, preceding, the all-round effect of injecing core home range in back. Can realize through above-mentioned limit structure that the compressor core collides with limit structure each other low noise effect and improve compressor core anti-seismic performance to this optimizes the user's body and experiences the sensation to the noise and improves the reliability that the compressor used in the environment of jolting of removing.
