Abstract
The utility model relates to a construction improvement type piston ring, include the piston ring body of making by elastic rubber material, open the centre of piston ring body has the mounting hole, at least it has an inward triangle -shaped groove to open on the outer face of cylinder of piston ring body, and it has an outside oil groove that unloads to open at least on the inner cylinder face of piston ring body, the cross -section of unloading the oil groove also is triangle -shaped. The utility model discloses an it has the triangle -shaped groove to open on the outer face of cylinder of elasticity piston ring and inner cylinder face, can prevent on the one hand when sealed, and the inefficacy of piston ring, on the other hand is because the effect of unloading the oil groove, can effectively improve the life of piston ring, improves the sealed effect of a thick liquid lid and a lacquer section of thick bamboo.
Description
Technical field
The utility model relates to piston ring field, particularly relates 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.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of Improved-structure piston ring.
The utility model 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 optimal technical scheme of the present utility model, the quantity of described vee gutter is equal with the quantity of oil unloading trough.
As optimal technical scheme of the present utility model, the angle of release of described vee gutter is 60 degree.
Compared with prior art, the beneficial effects of the utility model are: the utility model 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.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model;
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 the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is plan view of the present utility model, and Fig. 2 is plan view of the present utility model, 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 utility model 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.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
