Abstract
The utility model discloses a doublestage direction oil -free air compressor piston, which comprises a piston body, the sealing ring has been cup jointed in the piston body outside, still is fixed with two the same direction, the both ends at the piston body are fixed respectively to the guide ring, the sealing ring cup joints and fixes the upper end at the piston body respectively with one of them guide ring top -down, be equipped with the holding pin on the piston body. The utility model discloses a two guide rings lead from top to bottom to the piston in grades, make whole piston have the advantage that area of contact is little, the direction is accurate, not skew, and in addition, the guide ring has direction and sealed dual function, uses with the sealing ring cooperation, increases the effect of direction auxiliary seal, make compression cylinder have that the two -stage is sealed to be acted on to the work efficiency of compressor has been improved.
Description
Technical field
This utility model is related to the guiding and Sealing Technology of non-oil air compressor piston, and in particular to a kind of double jets
Oilless air compressor piston.
Background technology
Existing non-oil air compressor piston sealing is with guide frame using bayonet type free-standing piston ring and sealing
Ring structure, cause be oriented to it is inaccurate, leakage efficiency is low, not wear-resisting, reduce oil-free air compressor service efficiency and safeguard
Frequency is high, and maintenance cost is high.
The content of the invention
To solve the problems, such as prior art, this utility model provides a kind of double jets oilless air compressor piston, energy
Enough solution piston seals are inaccurate with the guiding that guide frame is present, and leakage efficiency is low, not wear-resisting problem, so as to improve pressure
The service efficiency of contracting machine, reduces maintenance cost.
For achieving the above object, the technical solution adopted in the utility model is：
A kind of double jets oilless air compressor piston, including piston body（1）, the piston body outside is socketed with sealing ring
（2）, it is further fixed on guide ring（3）And guide ring（4）, the guide ring（3）With（4）It is separately fixed at piston body（1）Two ends,
The sealing ring（2）With guide ring（3）It is socketed and is fixed on piston body respectively from top to bottom（1）Upper end.
The guide ring（3）And guide ring（4）It is identical.
The piston body（1）It is provided with holding pin（5）.
The beneficial effects of the utility model：
This utility model adopt two guide rings, guiding is classified up and down to piston, make whole piston have contact area it is little,
It is accurate to be oriented to, unswerving advantage.
The guide ring that this utility model is adopted has guiding and seals dual-use function, uses cooperatively with sealing ring, and increase is led
To auxiliary seal effect, make compression cylinder that there is two-stage sealing function, so as to improve the work efficiency of compressor.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
1 --- --- --- guide ring 4 --- guide ring 5 --- holding pin of sealing ring 3 of piston body 2.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect to realize this utility model is easy to understand, below
With reference to specific embodiment, the present invention is expanded on further.
With reference to Fig. 1, this specific embodiment is employed the following technical solutions：
A kind of double jets oilless air compressor piston, including piston body（1）, piston body outside is socketed with sealing ring（2）, also
It is fixed with identical guide ring（3）And guide ring（4）, guide ring（3）With（4）It is separately fixed at the two ends of piston body, sealing ring
（2）With guide ring（3）It is socketed and is fixed on piston body respectively from top to bottom（1）Upper end, piston body（1）It is provided with holding pin
（5）.
This specific embodiment adopts two guide rings（3）With（4）, guiding is classified up and down to piston, have whole piston
Have that contact area is little, be oriented to accurate, unswerving advantage.
The guide ring that this specific embodiment is adopted（3）With（4）With being oriented to and sealing dual-use function, with sealing ring（2）
Use cooperatively, increase and be oriented to auxiliary seal effect, make compression cylinder that there is two-stage sealing function, so as to improve the work of compressor
Make efficiency.
The ultimate principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
