In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of anti-gas blowby of mismatch
Engine piston ring, comprising: the first elastic metallic ring 1 and the second elastic metallic ring 2, the first elastic metallic ring 1 are superimposed
On the second elastic metallic ring 2, the first opening 11, the second elastic metallic ring 2 are provided on the first elastic metallic ring 1
On be provided with the second opening 21, be provided with positioning mechanism between the first elastic metallic ring 1 and the second elastic metallic ring 2 and keep away
Exempt from relative torsion.
In one preferred embodiment of the utility model, it is described first opening 11 and second opening 21 mutually stagger without
The part of coincidence.
In one preferred embodiment of the utility model, the first elastic metallic ring 1 and the second elastic metallic ring 2 are identical
The heart.
In one preferred embodiment of the utility model, the positioning mechanism includes positioning groove 12 and corresponding convex
Platform 22.
In one preferred embodiment of the utility model, 12 indent of positioning groove is arranged in the first elastic metallic ring 1
Bottom, 22 evagination of positioning convex platform is arranged in the top of the second elastic metallic ring 2 and extends in positioning groove 12.
In one preferred embodiment of the utility model, 22 height of positioning convex platform is not more than the depth of positioning groove 12
Degree.
In one preferred embodiment of the utility model, 22 height of positioning convex platform is greater than 1 He of the first elastic metallic ring
Axial gap of the second elastic metallic ring 2 in closure gasket groove.
The beneficial effects of the utility model are: a kind of engine piston ring for the anti-gas blowby of mismatch that the utility model is pointed out,
Installation and removal maintenance is relatively convenient, and when work, the first elastic metallic ring 1 and the second about 2 elastic metallic ring are bonded and synchronous
Mobile, gap is small and airflow channel is substantially not present, and along with the first opening 11 and the second opening 21 mutually stagger, forms mismatch
Structure has prevented the circulation of air-flow between the first elastic metallic ring 1 and the second elastic metallic ring 2, has avoided gas blowby problem, be conducive to
The power loss for reducing engine avoids the oil gas in crankcase from leaking problem, and structure is more reasonable, and functional reliability is strong, just
In processing and manufacturing and use.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is a kind of structural schematic diagram of one preferred embodiment of engine piston ring of the anti-gas blowby of mismatch of the utility model；
Fig. 2 is the part A enlarged drawing in Fig. 1.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Fig. 1 ~ Fig. 2 is please referred to, the utility model embodiment includes:
A kind of engine piston ring of the anti-gas blowby of mismatch, comprising: the first elastic metallic ring 1 and the second elastic metallic ring 2, institute
It states the first elastic metallic ring 1 to be superimposed upon on the second elastic metallic ring 2, the first elastic metallic ring 1 and the second elastic metallic ring 2
Mutually with one heart, using same metal material, stable structure, production convenience, the first elastic metallic ring 1 and the second elastic metallic ring 2
