Description
Technical field
The utility model relates to air compressor fields, more particularly to a kind of wear-resisting oilless air compressor inlet piston.
Background technique
Existing non-oil air compressor piston almost all use aluminum, the maximum drawback of aluminum piston be its intolerant to
Mill property.Also, in the long-term use process, the drawbacks of aluminum piston, will be more obvious.As compressor is run, aluminum is living
Plug can constantly be worn, and the efficiency that finally will lead to compressor gradually decreases.
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.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of wear-resisting oilless air compressor inlet pistons, realize
Compressor will not be with the operation of machine and efficiency reduces.
The utility model 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；
Be inside the piston body it is hollow, key seat is provided on piston body；The piston crown upper end is equipped with copper sheet, if copper sheet is equipped with
Dry longitudinal air inlet for running through piston crown.
One of preferred embodiment as the utility model, the copper sheet are set to the upper end center position of piston crown, and
A specially circular copper plate piece.
One of preferred embodiment as the utility model, the center position of the piston crown upper end offer a circle
Groove, circular groove is interior to be equipped with the circular copper plate piece mutually agreed with therewith.
One of preferred embodiment as the utility model, the upper surface and piston crown upper surface of the circular copper plate piece are flat
Together.
One of preferred embodiment as the utility model, the specific diameter of the circular copper plate piece are 30-32mm.
One of preferred embodiment as the utility model, the air inlet are specially six, and along the circle of circular copper plate piece
All equidistantly distributeds.
One of preferred embodiment as the utility model, the specific aperture of the air inlet are 4.5-5mm.
One of preferred embodiment as the utility model is additionally provided with a threaded hole on the copper sheet.
One of preferred embodiment as the utility model, the threaded hole are set to the center of copper sheet, and to downward
It extends to through piston crown.
One of preferred embodiment as the utility model, the specific aperture of the threaded hole are 4.5-5mm.
The utility model compared with prior art the advantages of be：
(1) structure is simple, easy to use；
(2) the piston crown upper end of the utility model is equipped with copper sheet；Copper sheet using wearability much stronger than aluminium replaces tradition
Aluminum piston keeps the high energy efficiency performance of oilless air compressor for a long time to greatly increase the wearability of piston；
(3) it only needs to be poured at the top of piston crown, can be obtained copper sheet, it is simple, convenient, it is conducive to industry
Change development.

Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
Embodiment 1
As shown in Figs. 1-5, the wear-resisting oilless air compressor inlet piston of one kind of the present embodiment, structure is simple, easy to use,
Including piston body 1 and it is set to the piston crown 2 of 1 upper end of piston body；Be inside piston body 1 it is hollow, be provided on piston body 1
Key seat 3；The center position of 2 upper end of piston crown offers a circular groove (not indicating in figure), is cast in circular groove
The circular copper plate piece 4 mutually agreed with therewith；The diameter of circular copper plate piece 4 is 30-32mm, 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 through piston crown 2；In addition, also driveing on circular copper plate piece 4, there are six the air inlets 42 that aperture is 4.5-5mm；
Six air inlets 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
Column are equally spaced.
Advantage of this embodiment is that：
(1) structure is simple, easy to use；
