Abstract
The utility model relates to the technical field of cylinder assemblies, in particular to a wear-resisting piston ring. The wear-resisting piston ring comprises a piston ring body, wherein a seal ring is arranged at the lower end of the inner side of the ring body; a ring of meshing teeth are arranged on the seal ring on the inner side of the ring body; the seal ring is an elastic rubber ring; teeth of the meshing teeth are half-elliptic. According to the utility model, the elastic rubber ring is arranged at the lower end of the inner side of the piston ring body, not only is a relatively sealed effect played, but also the pressure between the piston ring and a cylinder sleeve is reduced, and a ring of meshing teeth of which the teeth are half-elliptic are further arranged on the seal ring on the inner side of the ring body, so that the stability and the leakproofness of the ring body and the cylinder sleeve are improved, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to the technical field of cylinder assembly, especially a kind of anti-wear type piston ring.
Background technique
In order to improve the sealing of cylinder, avoid the leakage of pressurized gas, between piston and cylinder, be provided with a piston ring, the piston ring using is at present owing to being a simple ring body, in the process using, piston ring can rupture because pressure is too large, and the piston ring that takes regular exercise produces displacement, have a strong impact on the work of cylinder, greatly reduced working efficiency and workmanship.
Model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of anti-wear type piston ring.
The utility model solves the technological scheme that its technical problem adopts: a kind of anti-wear type piston ring, comprise piston ring ring body, and described ring body inside lower end is provided with seal ring, above described ring body inner seal circle, is provided with a circle tooth engaged.
According to another embodiment of the present utility model, further comprise that described seal ring is elastic rubber ring.
According to another embodiment of the present utility model, the teeth that further comprise described tooth engaged are half elliptic.
The beneficial effects of the utility model are, be provided with elastic rubber ring in piston ring ring body inside lower end, not only play the effect of sealing more, also reduce the pressure between piston ring and cylinder sleeve, and above ring body inner seal circle, being also provided with circle teeth is oval-shaped tooth engaged, improve stability and sealing between ring body and cylinder sleeve, simple in structure, easy to use.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. ring bodies in figure, 2. seal ring, 3. tooth engaged, 4. teeth.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of anti-wear type piston ring, comprises piston ring ring body 1, and ring body 1 inside lower end is provided with seal ring 2, and ring body 1 inner seal circle 2 is provided with a circle tooth engaged 3 above.Preferably, seal ring 2 is elastic rubber ring.The teeth 4 of tooth engaged 3 are half elliptic.
The utility model is provided with elastic rubber ring in piston ring ring body 1 inside lower end, not only play the effect of sealing more, also reduce the pressure between piston ring and cylinder sleeve, and it is oval-shaped tooth engaged 3 that ring body 1 inner seal circle 2 is also provided with circle teeth above, tooth engaged 3 is mainly for being engaged on cylinder sleeve, improve stability and sealing between ring body and cylinder sleeve, simple in structure, easy to use.
