Abstract
The utility model discloses an oil -free air compressor piston, establish a plurality of piston rings on the piston only including piston only and cover, piston only lateral wall circumference is equipped with a plurality ofly and the corresponding looping -in groove of piston ring, the looping -in inslot is equipped with a plurality of spacing lugs, be equipped with the corresponding spacing groove of a plurality of and spacing lug on the piston ring. Through the spacing lug of a plurality of settings at the looping -in inslot, can make that people are quick to be set up the piston ring cover behind the looping -in inslot, let limiting groove on the spacing lug embedding piston ring, accomplish the steady job to the piston ring, the installation steady job of piston ring that like this can be quick can effectually prevent the rotation of piston ring, prevents that the piston ring from producing the unnecessary wearing and tearing at the in -process that the piston used, improves the life of piston greatly.
Description
Technical field
The utility model relates to a kind of piston, and more particularly, it relates to a kind of oilless air compressor piston.
Background technique
Parts reciprocating in bucket cylinder body, at piston when moving reciprocatingly, just need can maintain good sealing relationship between piston and piston cylinder, so people just arrange the annular mounting groove for installing rubber piston ring on piston, and in mounting groove, piston ring is set, this makes it possible to the sealing increased in certain degree between piston and piston cylinder, so existing piston is divided into piston only and piston ring, its piston only can be divided into top, head and skirt section, and the piston ring arranged on piston only also exist design unreasonable, poor sealing performance, piston ring and piston only install the problems such as unstable.
Model utility content
For the deficiency that prior art exists, it is stable convenient that the purpose of this utility model is to provide a kind of piston ring and piston only to install, and the oilless air compressor piston of good sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of oilless air compressor piston, comprise piston only and be set in the some piston rings on piston only, described piston only sidewall circumference is provided with some annular mounting groove corresponding with piston ring, be provided with some spacing block sets in described annular mounting groove, described piston ring is provided with some restraining grooves corresponding with spacing block set.
Preferably, described annular mounting groove comprises spaced first sealing circular groove and the second sealing circular groove, and the groove width of described first sealing circular groove is a, and the groove width of described second sealing circular groove is b, a:b is 12:1.
Preferably, the second described sealing circular groove is two, is disposed on the sidewall close with piston head; Described first sealing circular groove is two, is disposed on below the second sealing circular groove.
Preferably, described spacing block set and the inconsistent end face of piston ring are arc surface.
Preferably, described spacing block set is fixedly installed on annular mounting groove sidewall, and described spacing block set is provided with the curved surface coincided with piston only sidewall.
By adopting technique scheme, by some spacing block sets be arranged in annular mounting groove, people can be made to be arranged on after in annular mounting groove by piston ring set fast, in the restraining groove allowing spacing block set embed on piston ring, complete the steady job to piston ring, like this can the installation steady job of piston ring fast, effectively can prevent the rotation of piston ring, produce unnecessary wearing and tearing in the process preventing piston ring from using at piston, greatly improve the working life of piston.

Reference character: 1, piston only; 11, top; 2, piston ring; 21, restraining groove; 3, annular mounting groove; 31, the first sealing circular groove; 32, the second sealing circular groove; 4, spacing block set; 41, arc surface; 42, curved surface.
Embodiment
Referring to figs. 1 through Fig. 5, the utility model oilless air compressor piston embodiment is described further.
A kind of oilless air compressor piston, the some piston rings 2 comprising piston only 1 and be set on piston only 1, described piston only 1 sidewall circumference is provided with some annular mounting groove 3 corresponding with piston ring 2, be provided with some spacing block sets 4 in described annular mounting groove 3, described piston ring 2 is provided with some restraining grooves 21 corresponding with spacing block set 4.By some spacing block sets 4 be arranged in annular mounting groove 3, people can be made to be set on by piston ring 2 fast after in annular mounting groove 3, in the restraining groove 21 allowing spacing block set 4 embed on piston ring 2, complete the steady job to piston ring 2, like this can the installation steady job of piston ring 2 fast, effectively can prevent the rotation of piston ring 2, produce unnecessary wearing and tearing in the process preventing piston ring 2 from using at piston, greatly improve the working life of piston.
Described annular mounting groove 3 comprises spaced first sealing circular groove 31 and the second sealing circular groove 32, and the groove width of described first sealing circular groove 31 is a, and the groove width of described second sealing circular groove 32 is b, a:b is 12:1.The ratio of the groove width of its first sealing circular groove 31 and the second sealing circular groove 32 is 12 to 1, this makes it possible to reasonable layout first on piston only 1 and seal circular groove 31 and the second sealing circular groove 32, can either rationally settle piston ring 2, increase the sealability of piston, but also wear resistance and the intensity of piston entirety can be strengthened greatly.
The second described sealing circular groove 32 is two, is disposed on the sidewall close with piston head 11; Described first sealing circular groove 31 is two, is disposed on below the second sealing circular groove 32.And on piston only 1, interval is provided with the annular mounting groove 3 of not groove width, greatly strengthen the sealing between piston and piston cylinder, improve working efficiency by the setting of some annular mounting groove 3.And the first sealing circular groove 31 be arranged on piston only 1 and the second sealing circular groove 32 are all two, and interval is arranged, some annular mounting groove 3 can either be made so more neatly reasonably to be arranged on piston only 1, sealing effect more efficiently can be played.
The end face that described spacing block set 4 is inconsistent with piston ring 2 is arc surface 41.Described spacing block set 4 is fixedly installed on annular mounting groove 3 sidewall, and described spacing block set 4 is provided with the curved surface 42 coincided with piston only 1 sidewall.And be arranged on the spacing block set 4 of annular mounting groove 3 sidewall; while playing piston ring 2 fixed effect; also more can be agreed with mutually with the restraining groove 21 on piston ring 2 by the effect of arc surface 41; and curved surface 42 just can keep fairing with whole piston only 1 sidewall; when preventing from spacing block set 4 and piston ring 2 from producing colliding; be damaged to piston ring 2, can protect more safely and effectively piston ring 2.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
