The O-shaped ring is one of sealing rings, is the most widely used one in hydraulic and pneumatic transmission systems, and is generally made of nitrile rubber, natural rubber, chloroprene rubber, ethylene propylene rubber, fluorine rubber, silicon rubber and blended rubber. The section of an ordinary O-shaped ring is circular, but the O-shaped ring is easy to deform flatly after being extruded, and the sealing effect is reduced or lost, so that a novel sealing ring is needed in the field to solve the problems.

For example, a sealing ring (application number: 200820088050.X) disclosed in chinese patent document includes a sealing ring main body, sealing teeth are cooperatively arranged on an inner ring of the sealing ring main body, friction teeth are cooperatively arranged on an outer ring of the sealing ring main body, the sealing teeth are in two-step shape, the friction teeth are in four-convex shape, and the sealing ring main body, the friction teeth and the sealing teeth are integrally formed. However, the sealing ring has the problems of insufficient firmness in positioning and unsatisfactory sealing effect

As another example, a novel seal ring (application No. 201810871677.0) disclosed in the chinese patent document is a closed-loop O-ring, in which an annular groove is provided in the middle, the annular groove divides the seal ring into an inner ring and an outer ring, the inner wall of the inner ring is inclined inward, the outer wall of the outer ring is inclined outward, small domes are provided at the opening ends of the annular groove of the inner ring and the outer ring, the small domes extend away from the annular groove and exceed the inner ring and the outer ring, respectively, and a large dome is provided at the bottom of the annular groove to connect the inner ring and the outer ring; the novel sealing ring is of an integrated structure. But this novel sealing washer exists the not high and sealed effect ideal problem inadequately of support intensity.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a novel O-shaped ring which is high in supporting strength and good in sealing effect.

The purpose of the utility model can be realized by the following technical scheme: novel O type circle, including annular body, its characterized in that, the middle part of body be equipped with the support ring, the middle part of support ring be equipped with the cavity, the lateral wall of support ring be equipped with a plurality of connection convex bodies just connection convex body wrap up in this is internal.

In the novel O-shaped ring, the arc-shaped convex bodies are symmetrically arranged by taking the central line of the connecting convex body as the center.

In the novel O-shaped ring, the radii of the arc-shaped convex bodies are equal.

In the novel O-shaped ring, the outer side wall of the arc convex body is provided with a wavy connecting surface. The outer side wall of the arc convex body is provided with the wavy connecting surface, so that the connecting effect of the arc convex body and the body is better, and the service life is prolonged.

In the novel O-shaped ring, the number of the connecting convex bodies is 3-6, and the connecting convex bodies are uniformly arranged on the outer side wall of the support ring.

In the novel O-shaped ring, the body is made of nitrile rubber. The body is made of nitrile rubber, and has the advantage of good sealing effect.

In the novel O-shaped ring, the support ring is made of polytetrafluoroethylene materials. The support ring is made of polytetrafluoroethylene materials, so that the support ring has the advantages of high support strength, high temperature resistance, corrosion resistance and longer service life.

Compared with the prior art, this novel O type circle has following advantage:

1. the middle part of the body is provided with the support ring, the middle part of the support ring is provided with the cavity, and the outer side wall of the support ring is provided with the connecting convex body, so that the support strength of the novel O-shaped ring is improved, the O-shaped ring can be prevented from being excessively deformed when being subjected to a large external force, and the sealing effect is improved;

2. the outer end of the connecting convex body is provided with an arc convex body, and the arc convex body is positioned inside the body, so that the supporting effect of the novel O-shaped ring is improved;

3. the support ring is made of polytetrafluoroethylene materials, so that the support ring has the advantages of high support strength, high temperature resistance, corrosion resistance and longer service life.
