Abstract
The utility model discloses a connecting rod mounting structure of an opposed type double cylinder refrigeration compressor, which comprises a crankcase, a crankshaft, a right connecting rod, a left connecting rod, a right piston pin, a left piston pin, a right piston, a left piston, a right valve group, a left valve group, a motor, a support spring and a housing. A right cylinder and a left cylinder are arranged on the crankcase. The right piston and the left piston are respectively arranged in the right cylinder and the left cylinder. The left connecting rod and the right connecting rod are respectively connected with the left piston and the right piston. A middle shaft sleeve is arranged on the right connecting rod. An upper shaft sleeve, a groove and a lower shaft sleeve are arranged on the left connecting rod. The middle shaft sleeve, the upper shaft sleeve and the lower shaft sleeve are respectively sleeved onto the crankshaft. Due to the adoption of the above mounting structure, the reciprocating inertia forces of parts during movement, such as pistons, connecting rods, piston pins and the like, are greatly reduced. Meanwhile, the movement balance of the above system can be realized through the miniaturized structure and both the height and the weight of the whole machine compressor are reduced. Therefore, both the refrigerating output of the compressor, and the ratio of the refrigerating output to the net weight of the compressor are effectively improved.
