Abstract
The invention relates to a piston ring with an improved structure. The piston ring comprises a piston ring body made of an elastic rubber material. An installing hole is formed in the middle of the piston ring body. At least one inward triangular groove is formed in the outer cylindrical face of the piston ring body. At least one outward oil discharging groove is formed in the inner cylindrical face of the piston ring body. The section of the oil discharging groove is triangular. As the triangular grooves are formed in the outer cylindrical face and the inner cylindrical face of the elastic piston ring, on one hand, the piston ring is prevented from losing efficacy in the sealing process, on the other hand, the service life of the piston ring can be effectively prolonged by means of the effect of the oil discharging groove, and the sealing effect of a slurry cover and a paint cylinder is improved.
Description
Technical field
The present invention relates to piston ring field, particularly relate to a kind of Improved-structure piston ring.
Background technique
Piston ring is the metal ring entering piston groove inside for down, and piston ring is divided into two kinds: compression ring and machine oil ring.Compression ring can be used to the burning mixture of sealing combustion indoor; Machine oil ring is then used for striking off machine oil unnecessary on cylinder.Piston ring a kind ofly has the metallic elastic ring expanding outwardly more greatly distortion, and it is mounted in its corresponding circular groove of section.Back and forth and the piston ring of rotary motion, rely on the pressure difference of gas or liquid, seal at ring periphery and cylinder and being formed between ring and a side of annular groove.
Piston ring for sealing above-mentioned pump cover and paint can in prior art is made up of elastic material, but as a complete unit, sealing effect is not very desirable.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of Improved-structure piston ring.
The present invention is achieved through the following technical solutions:
A kind of Improved-structure piston ring, comprise the piston ring body be made up of elastic rubber material, the centre of described piston ring body has mounting hole, the external cylindrical surface of described piston ring body at least has an inside vee gutter, the inner cylindrical surface of piston ring body at least has an outside oil unloading trough, and the cross section of described oil unloading trough is also triangular in shape.
As the preferred technical solution of the present invention, the quantity of described vee gutter is equal with the quantity of oil unloading trough.
As the preferred technical solution of the present invention, the angle of release of described vee gutter is 60 degree.
Compared with prior art, the invention has the beneficial effects as follows: the present invention by having vee gutter on the external cylindrical surface and inner cylindrical surface of elastic piston ring, when can prevent sealing on the one hand, the inefficacy of piston ring, on the other hand due to the effect of oil unloading trough, effectively can improve the working life of piston ring, improve slurry lid and the sealing effect painting cylinder.

Fig. 2 is plan view of the present invention;
Fig. 3 be A in Fig. 1 ?A sectional view.
In figure: 1 ?piston ring body; 2 ?mounting hole; 3 ?vee gutter; 4 ?oil unloading trough.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is plan view of the present invention, and Fig. 2 is plan view of the present invention, Fig. 3 be A in Fig. 1 ?A sectional view.
Described a kind of Improved-structure piston ring, comprise the piston ring body 1 be made up of elastic rubber material, the centre of described piston ring body 1 has mounting hole 2, the external cylindrical surface of described piston ring body 1 at least has an inside vee gutter 3, the inner cylindrical surface of piston ring body 1 at least has an outside oil unloading trough 4, and the cross section of described oil unloading trough 4 is also triangular in shape.
The quantity of described vee gutter 3 is equal with the quantity of oil unloading trough 4, and the angle of release of described vee gutter 3 is 60 degree.
To sum up, the present invention passes through to have vee gutter on the external cylindrical surface and inner cylindrical surface of elastic piston ring, when can prevent sealing on the one hand, the inefficacy of piston ring, on the other hand due to the effect of oil unloading trough, effectively can improve the working life of piston ring, improve the sealing effect of slurry lid and paint cylinder.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
