Problems solved by technology

[0003] In the current assembly structure of the existing piston assembly, the piston and the connecting rod are usually rigidly connected. However, although the piston and the connecting rod with this rigid connection structure can meet the basic needs of use, the rigid connection structure is very easy to use The lateral force is formed during the working process, which increases the friction between the piston and the cylinder, and increases the working loss of the piston assembly accordingly, which seriously restricts the overall working efficiency of the compressor.

Abstract

The invention discloses a piston component, wherein the top of a piston is provided with an assembly cavity, the bottom of the assembly cavity is provided with a ball-shaped groove, and the upper side of the piston is coaxially provided with a connecting rod; the bottom end of the connecting rod is provided with a ball head which is rotatably inserted in the ball-shaped groove in a matching manner, an air hole penetrates through the piston along the axial direction and is communicated with the assembly cavity and the lower space of the piston, and the bottom of the piston is provided with an air suction valve fixing device matched with an air suction valve. During a working process, by virtue of a spherical matching structure formed by the inserting of the ball head and the ball-shaped groove, the connecting rod with 360 degrees of freedom can be ensured, the influence of the lateral force generated in an equipment operation process on a piston component main body structure is effectively avoided, and the frictional loss of the piston component is correspondingly decreased, so that the whole working efficiency of a compressor is correspondingly improved. The invention further discloses the compressor used for the piston component.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a piston assembly. The invention also relates to a compressor using the piston assembly. Background technique [0002] Compressor is a very common refrigeration system accessory equipment, and the piston assembly is the main working component of the compressor, and its working performance is also increasingly concerned by people. [0003] In the current assembly structure of the existing piston assembly, the piston and the connecting rod are usually rigidly connected. However, although the piston and the connecting rod with this rigid connection structure can meet the basic needs of use, the rigid connection structure is very easy to use The lateral force is formed during the working process, which increases the friction between the piston and the cylinder, and increases the working loss of the piston assembly accordingly, thus seriously restricting the overall working effic...
