Limiting structure for compressor

Abstract

The invention provides a limiting structure for a compressor, belonging to the field of refrigeration compressors. The limiting structure comprises a shell and a machine core located in the shell, wherein a plurality of pressure springs are arranged between the machine core and the shell, a limiting pin is further arranged on the machine core, a limiting ring is arranged on the inner side of the shell, and the limiting pin is inserted into the limiting ring. The limiting structure has an all-dimensional limiting function, the release of the springs can be prevented, and the metal impact noisecan be prevented; and the limiting structure is simple and easy to assemble.

Description

technical field [0001] The invention relates to the field of refrigeration compressors, in particular to a compressor position limiting structure. Background technique [0002] Existing refrigerator compressors are all limited by the cylinder block on the movement or the cylinder head and the housing. Usually, a plurality of limit ears are protruded from the front, back, left, and right directions of the cylinder seat. There is a certain distance between the limit ears and the housing, and a certain groove or protrusion is stamped on the upper cover to limit the position. There is at least one limit point in each direction of front, rear, left, right, up, down, and more. There are many limit points and many control points, and the cylinder block, shell, and cylinder head are all made of metal. The collision between the movement and the shell during transportation is prone to metal impact Noise, and it is easy to produce metal powder, causing the compressor to be stuck. Co...
