Abstract
The utility model discloses a non-opening piston ring which comprises a ring body with interfaces. The utility model is characterized in that the interfaces are mutually in interlacing superposition, one superimposing on the other, or in a convex-concave inserted superposition. The utility model has the advantage of the interfaces mutually in interlacing superposition. Two vertical directly touching sides on the opening of the sealing ring are changed to the present interlacing superposition structure; the original straight flanging gap on the interfaces are converted into the present broken line connecting gap. Therefore, the piston ring can avoid the direct gas leakage from the opening in the whole busy period, which ensures the sealing property of the cylinder as much as possible, ensures sufficient combustion of the engine fuel, reduces the exhaust emission pollution and prolongs the service life of the piston ring.
Description
Technical field
The utility model relates to a kind of piston ring, especially relates to a kind of Openingless piston ring.
Background technique
Two contact edges of the existing gap-clearance of piston rings of using always place are vertical plane, in use, and because of the wearing and tearing of ring and cylinder body, piston ring gap occurs and increase, cause the sealability variation, cause compressed capability to degenerate, the prominent mistake of power character can appear in time length, increases energy consumption and increases exhaust pollution.
The model utility content
The purpose of this utility model is to provide the Openingless piston ring of a kind of good seal performance, long service life.
For achieving the above object, the utility model can adopt technique scheme:
Openingless piston ring described in the utility model, it comprises the ring body that has interface, it is characterized in that: described interface is interlaced stacked setting.
Described interface is upper and lower staggered stacked setting.
Described interface is the stacked setting of protruding, recessed grafting.
Advantage of the present utility model is that interface is interlaced stacked setting, two vertical contact edges that are about to the seal ring opening change present staggered stacked structure into, originally jointing straight line connection slit becomes present broken line connection slit, make piston ring in whole life cycle, can both avoid the direct leakage of opening gas, guarantee the sealability of cylinder to greatest extent, guaranteed the abundant burning of motor fuel, reduce the pollution of toxic emission, also prolonged the working life of piston ring simultaneously.
Description of drawings
Fig. 1 is the side-looking structural representation of a kind of mode of execution of the utility model.
Fig. 2 is the side-looking structural representation of the another kind of mode of execution of the utility model.
Embodiment
Embodiment 1:
Openingless piston ring as shown in Figure 1, it comprises the ring body 2 that has interface 1, described interface 1 is upper and lower staggered stacked setting.The slit of jointing is a broken line like this, has improved the sealing of piston ring.
Embodiment 2:
The another kind of mode of execution of Openingless piston ring is the ring body 2 that has interface 1 as shown in Figure 2, and described interface 1 is the stacked setting of protruding, recessed grafting.Such structure makes the slit broken line inflection repeatedly of jointing, and its sealability is better.
Claims (3)
1, a kind of Openingless piston ring, it comprises the ring body (2) that has interface (1), it is characterized in that: described interface (1) is interlaced stacked setting.
2, Openingless piston ring according to claim 1 is characterized in that: described interface (1) is upper and lower staggered stacked setting.
3, Openingless piston ring according to claim 1 is characterized in that: described interface (1) is the stacked setting of protruding, recessed grafting.
