Abstract
The utility model discloses a piston ring which comprises a ring body, a first end part, and a second end part, wherein a horizontal groove is formed in the first end part, a protrusion corresponding to the groove is formed in the second end part, and the protrusion is embedded with the groove after installation. A sealing piece is further adhered to the second end part. The groove and the protrusion are both formed in the center of the ring body. The depth of the groove is equal to the height of the protrusion and is 50mm. The sealing piece is an elastic sealing piece. The piston ring has the advantages of being simple in structure, and easy to process. Elastic sealing is adopted so that the piston ring is high in sealing performance and capable of effectively bearing pressure brought by the expansion of the piston ring which is heated, and the service life of the piston ring is greatly prolonged.
Description
Technical field
The utility model belongs to engine art, particularly a kind of piston ring on motor.
Background technique
The conventional piston ring comprises ring body, first end and the second end, certain gap is left after installing in two end part, the sealing of piston ring is just poor like this, but the gap must be left in two end part, piston ring can not damaged after heating is expanded, this is the problem of good method solution never in the piston ring field.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of piston ring of good seal performance.
To achieve these goals, technical solution adopted in the utility model is:
A kind of piston ring comprises ring body, first end and the second end, and described first end is provided with a cross groove, and the second end is provided with the projection corresponding with described groove, and described groove is chimeric after installing with projection, also comprises being bonded with Sealing on the second end.
As preferably, described groove and projection all are located at the center portion of ring body.
As preferably, the degree of depth of described groove equals the height of projection and is 50mm.
As preferably, described Sealing adopts elastomer seal.
The beneficial effects of the utility model: the utility model is simple in structure, and elastic packing is adopted in easily processing, and sealability is high, and can effectively bear the pressure that the piston ring expanded by heating brings, and the piston ring life-span is increased greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of piston ring as shown in Figure 1, comprise ring body 1, first end 2 and the second end 3, described first end 2 is provided with a cross groove 4, the second end 3 is provided with the projection 5 corresponding with described groove 4, described groove 4 is chimeric after installing with projection 5, also comprises being bonded with Sealing 6 on the second end 3.Described groove 4 and projection 5 all are located at the center portion of ring body 1.The degree of depth of described groove 4 equals the height of projection 5 and is 50mm.Described Sealing 6 adopts elastomer seal.
The utility model is simple in structure, and elastic packing is adopted in easily processing, and sealability is high, and can effectively bear the pressure that the piston ring expanded by heating brings, and the piston ring life-span is increased greatly.Be more than the utility model preferred forms, in related domain, those skilled in the art's simple change and replacement are all within protection domain of the present utility model.
