Abstract
The utility model relates to a piston of a compressor for a refrigerator, comprising a cylindrical piston body. The cylindrical surface of the cylindrical piston body is provided with a piston pin hole in a penetrating manner; the internal wall of the piston is provided with a piston pin hole enhancing boss; the surface of the push end of the cylindrical piston body is provided with a cylindrical lug boss which has the height h, wherein the piston pin hole enhancing boss and the outer edge of the connecting end of the piston body have the height difference H which is larger than h. The piston of the compressor for the refrigerator has simple structure, scientific and reasonable design, light weight, good sealing effect by matching with a piston hole and simple machining on the basis of improving the performance of the compressor, and is capable of effectively improving the production efficiency.
Description
Technical field
The utility model belongs to the freezer compressor field, especially a kind of freezer compressor piston.
Background technique
Compression refrigerant is arranged in the compressor casing piston hole with piston in the freezer compressor, and piston is entered in the piston hole by motor driving, linkage mechanism transmission, and refrigerant is pressed into cylinder cap in being recycled to refrigeration system by the exhaust port on the valve plate.The freezer compressor piston comprises a cylindrical piston body at present, directly upwards run through in cylindrical piston body cylndrical surface and to be shaped on piston pin hole, linkage mechanism is by wrist pin and piston hinge dress, for better support piston pin, around the piston pin hole of piston inner wall, be shaped on piston pin hole and strengthen platform, this piston pin hole is strengthened platform and is flushed with the cylindrical piston connecting end outer rim of linkage mechanism one side, in order better to realize compression refrigerant, on the face of the propelling end of cylindrical piston, make a cylindrical boss, this cylindrical boss position is corresponding with the exhaust port position on the valve plate, the diameter of this cylindrical boss is less than the diameter of valve plate upper air-vent, though this kind improvement has had raising to intake efficiency, but also run into the difficulty of processing and fabricating, when not having cylindrical boss, the manufacturing procedure of outside piston can a plurality of pistons of time processing, because can be corresponding mutually between piston and the piston, not not at interval, but after the piston after process is improved installs cylindrical boss additional, when the rotation processing excircles, very easily cause hitting wheel, damage machine; Perhaps can only carry out cylindrical processing, greatly reduce the throughput of equipment single piston, and the oil groove that is shaped on the existing cylindrical piston cylndrical surface, can only play lubricated effect, can not satisfy the requirement of higher raising compressor performance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of freezer compressor piston is provided, and this piston structure is simple, design science is reasonable, and is in light weight, effective with cylinder piston hole fitted seal, improving on the basis of compressor performance, processing is simple, and manufacturing efficiency is higher.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of freezer compressor piston, comprise the cylindrical piston body, on the cylndrical surface of cylindrical piston body, run through and be shaped on piston pin hole, on piston inner wall, be shaped on piston pin hole and strengthen platform, on the face of cylindrical piston body propelling end, be shaped on cylindrical boss, the height of cylindrical boss is h, and wherein the height difference of piston pin hole reinforcement platform and piston only connecting end outer rim is H, and H＞h.
And, the described coaxial O-ring cylinder that is shaped on the cylndrical surface of holding a side, the coaxial guide cylinder face that is shaped on the cylndrical surface of cylindrical piston body connecting end one side of advancing at the cylindrical piston body.
Advantage of the present utility model and beneficial effect are:
1, this freezer compressor piston advances on the face of holding at the cylindrical piston body and is shaped on cylindrical boss, the height of cylindrical boss is h, wherein the height difference of piston pin hole reinforcement platform and piston only connecting end outer rim is H, and H＞h, this kind structure can be in the outside piston course of working, a plurality of piston compactnesses are arranged in a row processing together, and processing technology is simple, and manufacturing efficiency is higher.
2, this freezer compressor piston advances the coaxial O-ring cylinder that is shaped on the cylndrical surface of holding a side at the cylindrical piston body, the coaxial guide cylinder face that is shaped on the cylndrical surface of cylindrical piston body connecting end one side, the O-ring cylinder can satisfy the requirement of sealing refrigerant, the guide cylinder face can make piston keep straight reciprocating motion, this kind structure effectively reduces the area of contact of piston and piston hole, increase oil storage space, better lubricated, reduce frictional work, improve electric efficiency, and when guaranteeing the piston guide effect, reduced the length of piston, alleviate the weight of piston, reduced the input work consumption of whole compressor system, improved compressor assembly efficient.
3, the utility model piston structure is simple, and design science is reasonable, and is in light weight, effective with the piston hole fitted seal, improving on the basis of compressor performance, and processing is simple, is a kind of freezer compressor piston that can effectively enhance productivity.
