Existing non-oil air compressor piston almost all uses aluminum, the maximum drawback of aluminum piston be its intolerant to
Mill property.It, will be more apparent the drawbacks of aluminum piston also, during long-term use.With compressor operating, aluminum is lived
Plug can constantly be worn, and finally the efficiency of compressor will be caused to continuously decrease.
Accordingly, it is badly in need of a kind of anti abrasive oilless air compressor piston at present, to realize that compressor will not be with the fortune of machine
It goes and efficiency reduction.
Invention content
Technical problem to be solved by the present invention lies in a kind of wear-resisting oilless air compressor inlet piston is provided, compression is realized
Machine will not the efficiency reduction with the operation of machine.
The present invention solves above-mentioned technical problem using following technical scheme：
A kind of wear-resisting oilless air compressor inlet piston, including piston body and the piston crown for being set to piston body upper end；
It is hollow inside the piston body, key seat is provided on piston body；The piston crown upper end is equipped with copper coin, if copper coin is equipped with
Dry longitudinal air admission hole for running through piston crown.
One of preferred embodiment as the present invention, the copper coin are set to the upper end center position of piston crown, and specific
For a circular copper plate piece.
As one of the preferred embodiment of the present invention, it is round recessed that the center position of the piston crown upper end offers one
Slot, circular groove is interior to be equipped with the circular copper plate piece mutually agreed with therewith.
One of preferred embodiment as the present invention, the upper surface of the circular copper plate piece is concordant with piston crown upper surface.
One of preferred embodiment as the present invention, specific a diameter of 30-32mm of the circular copper plate piece.
One of preferred embodiment as the present invention, the air admission hole is specially six, and along the circumference etc. of circular copper plate piece
Spacing is distributed.
The specific aperture of one of preferred embodiment as the present invention, the air admission hole is 4.5-5mm.
One of preferred embodiment as the present invention, is additionally provided with a threaded hole on the copper coin.
One of preferred embodiment as the present invention, the threaded hole is set to the center of copper coin, and extends downward into
Through piston crown.
The specific aperture of one of preferred embodiment as the present invention, the threaded hole is 4.5-5mm.
The present invention compared with prior art the advantages of be：
(1) simple in structure, easy to use；
(2) piston crown upper end of the invention is equipped with copper coin；Traditional aluminum is replaced much stronger than the copper coin of aluminium using wearability
Piston makes the high energy efficiency performance of oilless air compressor be kept for a long time to greatly increase the wearability of piston；
(3) it only needs to be poured into a mould at the top of piston crown, you can copper coin is obtained, it is simple, convenient, it is conducive to industry
Change development.

Specific implementation mode
It elaborates below to the embodiment of the present invention, the present embodiment is carried out lower based on the technical solution of the present invention
Implement, gives detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
As shown in Figs. 1-5, a kind of wear-resisting oilless air compressor inlet piston of the present embodiment, it is simple in structure, easy to use,
Including piston body 1 and it is set to the piston crown 2 of 1 upper end of piston body；1 inside of piston body is hollow, is provided on piston body 1
Key seat 3；The center position of 2 upper end of piston crown offers a circular groove (not indicated in figure), is cast in circular groove
The circular copper plate piece 4 mutually agreed with therewith；A diameter of 30-32mm of circular copper plate piece 4, upper surface and 2 upper surface of piston crown
Concordantly.
The center of 4 upper surface of circular copper plate piece is provided with a threaded hole 41；41 aperture of threaded hole is 4.5-5mm, and
It extends downward into and runs through piston crown 2；In addition, also being driveed on circular copper plate piece 4, there are six the air admission holes 42 that aperture is 4.5-5mm；
Six air admission holes 42 are longitudinal to run through piston crown 2, and centered on threaded hole 41, along 4 periphery of circular copper plate piece circumferentially battle array
Row are equally spaced.
Advantage of this embodiment is that：
(1) simple in structure, easy to use；
