Easy-to-assemble-disassemble counterweight device for compressor piston

The invention relates to the technical field of compressor parts, in particular to an easy-to-assemble-disassemble counterweight device for a compressor piston. The easy-to-assemble-disassemble counterweight device comprises a piston body, wherein a middle connecting through hole used for connecting a piston rod is formed in the center of the interior of the piston body. According to the easy-to-assemble-disassemble type counterweight device for the compressor piston, lateral counterweight blind holes with limiting sealing grooves are formed in the piston body, the quality of each column of pistons is balanced by inserting counterweight screw rods which are in surface threaded connection with inner thread limiting plates into a built-in guide hole and lead used for filling and counterweight, the reciprocating inertia force is balanced, and the smooth operation of a compressor is guaranteed; and each part is connected through clamping fixation and thread fixation, so that the device issimpler and more convenie
