Problems solved by technology

[0007] But this splicing structure design requires a rubber ring seal between the piston rod 24 and the piston head 23, and the fastening bolt 21 needs to be tightened in front of the piston head 23, which may damage the piston head 23. It is easy to produce problems such as damage to the suction valve plate 22 during the fastening process, which seriously reduces the performance of the linear compressor
[0008] At the same time, in order to ensure that the piston has good sealing performance, the bolt 21 needs to be made of a metal material to provide a higher fastening strength, resulting in a heavier piston and higher production costs.

Embodiment Construction

[0061] Such as image 3 Shown is a schematic diagram of the piston of the linear compressor of the present invention, the piston includes a piston head 33 and a piston rod 34 , and the piston head 33 and the piston rod 34 are fixedly connected by bolts 31 and nuts 35 .

[0062] The bolt 31 includes a bolt head 311 and a screw rod 312 . A suction valve plate 32 is arranged between the bolt head 311 and the piston head 33 .

[0063] The center of the piston head 33 defines a through positioning hole 331 . The part of the piston rod 34 close to the piston head 33 is a solid section 341 , and the rest is a hollow section 342 . The center of the solid section 341 defines a through positioning through hole 3411 , the positioning through hole 331 of the piston head 33 and the positioning through hole 3411 of the solid section 341 are passed through by the screw rod 312 . Such positioning through-hole technology facilitates processing and improves production efficiency. The solid ...

Abstract

The invention discloses a linear compressor and a piston thereof. The piston comprises a piston head and a piston rod, wherein the piston head and the piston rod are fixedly connected through a bolt and a nut. According to the piston of the linear compressor, the threaded end of a threaded rod is fastened with the nut to prevent the piston from being damaged, so that the assembly reject ratio is reduced, and the performance of the compressor is improved.

Description

technical field [0001] The invention relates to a linear compressor, in particular to a piston of a linear compressor. Background technique [0002] The linear compressor sucks the refrigerant gas into the cylinder, and uses the linear driving force of the linear motor to make the piston linearly reciprocate in the cylinder to compress the fluid, and then discharge the compressed fluid. Since the linear compressor is ultimately compressed by the piston, the material used for the piston requires high hardness, high wear resistance, high temperature resistance, high temperature abrasion resistance, and stable thermal expansion coefficient. The splicing structure can reduce the cost, but it is prone to poor gas flow path, air leakage at the connection, low coaxiality of the connection, and skewing during splicing. [0003] Such as figure 1 As shown, the interior of the linear compressor 1 is axisymmetric. The linear compressor 1 includes a linear motor, and the mover componen...
