Abstract
The utility model relates to a limit structure, especially a compressor piston structure, the whole hollow circular cylinder that is of piston, piston upper surface opening sets up, and surface closed sets up under the piston, the piston lower surface is provided with circular arch (1), piston surface intermediate position is equipped with annular groove (2), annular groove (2) are gone up the symmetry and are provided with two little through -hole (3), two little through -hole (3) and the inside intercommunication of piston, still be provided with two big through -hole (4) on the piston surface, two big through -hole (4) and the inside intercommunication of piston, piston inside kenozooecium (5) structure is I -shaped setting, the utility model discloses among the technical scheme, designed a compressor piston structure, the dead phenomenon of card no longer appears in the fine messenger's connecting rod of this kind of whole, can not cause compressor power bigger than normal.
Description
Technical field
The utility model relates to a kind of piston structure, particularly a kind of compressor piston structure.
Background technique
Compressor is applied widely at industry, civil area, in refrigeration appliance field as air-conditioning, refrigerator etc. just need to use compressor; And along with the lasting raising of people's living standard, the life of compressor and people is more and more closer.Containing piston in compressor, after there is connecting rod and Piston assembling in current plunger designs, when operating about connecting rod, have the possibility of encountering connecting rod, sometimes touch the not obvious phenomenon of sometimes touching of phenomenon obvious, through technical inspection just this design reasons cause compressor horsepower bigger than normal.
Model utility content
Technical problem to be solved in the utility model is to provide the compressor piston structure that a kind of cost of production is low, compressor horsepower can not be caused bigger than normal.
For solving the problems of the technologies described above, the utility model realizes as follows: design a kind of compressor piston structure, it is characterized in that: piston entirety is in hollow circular cylinder, and piston upper surface opening is arranged, and piston lower surface is closed and arranged; Piston lower surface is provided with circular protrusions; Outer surface of piston neutral position is provided with annular groove; Annular groove is symmetrically arranged with two small through hole, two small through hole are communicated with internal piston; Outer surface of piston is also provided with two large through-holes, two large through-holes are communicated with internal piston; In piston, hollow portion structure is I-shaped setting.
Further, described hollow portion top and hollow portion bottom symmetrically arc setting.
Further, described two large through-holes are symmetricly set on the both sides of I-shaped hollow portion.
Further, the upper through hole that a large through-hole in described two large through-holes is also provided with piston is communicated with.
Further, a circular hollow portion is also provided with between described hollow portion and piston upper surface.
Good effect of the present utility model: in technical solutions of the utility model, devises a kind of compressor piston structure, and this entirety well makes connecting rod no longer occur stuck phenomenon, and compressor horsepower can not be caused bigger than normal.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
As shown in the figure, compressor piston structure described in the utility model, is characterized in that: piston entirety is in hollow circular cylinder, and piston upper surface opening is arranged, and piston lower surface is closed and arranged; Piston lower surface is provided with circular protrusions 1; Outer surface of piston neutral position is provided with annular groove 2; Annular groove 2 is symmetrically arranged with two small through hole, 3, two small through hole 3 to be communicated with internal piston; Outer surface of piston is also provided with two large through-holes, 4, two large through-holes 4 to be communicated with internal piston; In piston, hollow portion 5 structure is I-shaped setting.
Further, described hollow portion 5 top and hollow portion 5 bottom symmetrically arc 6 arrange.
Further, described two large through-holes 4 are symmetricly set on the both sides of I-shaped hollow portion 5.
Further, the upper through hole 7 that a large through-hole 4 in described two large through-holes 4 is also provided with piston is communicated with.
Further, a circular hollow 8 is also provided with between described hollow portion 5 and piston upper surface.
In actual applications, the pattern that hollow portion 5 is arranged in work shape avoids connecting rod and occurs stuck phenomenon.
