Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 3, the embodiment discloses a rubber ring, which includes a rubber ring body 1, and is characterized in that the rubber ring body 1 includes an upper gasket 101, a lower gasket 102, and an intermediate layer 103, and the upper gasket 101 and the lower gasket 102 are clamped on two sides of the intermediate layer 103; an elastic cavity 113 is formed in the middle of the middle layer 103, squeezing blocks 123 are symmetrically arranged on two sides of the elastic cavity 113, and a supporting block 133 with an oval cross section is arranged between the pair of squeezing blocks 123; a conical opening 143 is formed in one side, facing the supporting block 133, of the extrusion block 123, a deformation strip 3 is arranged in the conical opening 143, and driving blocks 153 which are matched with the conical opening 143 and abut against the deformation strip 3 are arranged on two sides, facing the extrusion block 123, of the supporting block 133; the middle parts of the upper gasket 101 and the lower gasket 102 far away from the middle layer 103 are provided with positioning convex edges 2.

When the pipeline extrudes the upper surface and the lower surface of the rubber ring, the extrusion block 123 in the elastic cavity 113 can be deformed, the deformation can reduce the conical opening 143 of the extrusion block 123, because the two sides of the conical opening 143 are small, the middle part is large, so the two sides can be firstly reduced, and the deformation strip 3 clamped in the conical opening 143 can be bent towards the opening direction, as shown in fig. 3, the bent deformation strip 3 can generate a force for extruding towards the middle part to the driving block 154, so that the pressure is applied to the middle supporting block 133 to enable the middle part of the supporting block 133 to be protruded, so that the positioning convex edge is protruded towards the direction of the pipeline, the upper gasket and the lower gasket are tightly attached to the inner wall of the pipeline, and the sealing effect of the upper gasket and the lower gasket is improved; simultaneously, the upper gasket and the lower gasket are supported, so that the rubber ring is prevented from being deformed due to long-time extrusion, and the sealing effect is poor.
