[0006] A water pipe rubber sealing ring with better waterproof performance, comprising a sealing ring body, a pressure receiving part for contacting the end surface of the pipeline is arranged on the inner side of the middle position of the sealing ring body, a filling extrusion ring groove is arranged in the middle position of the pressure receiving part, and a plurality of extrusion pieces arranged in an annular array are inserted into the filling extrusion ring groove.

[0007] Further, the protection ring piece is fixedly arranged on the two side walls of the filling extrusion ring groove, and the extrusion pieces are arranged between the protection ring pieces.

[0008] Further, the deformed arc part is arranged at the position close to the center of the pressure receiving part.

[0009] Further, the arc plate fixedly arranged on the extrusion pieces is arranged in the ring groove in the middle of the outer side surface of the sealing ring body.

[0010] Further, a groove part is arranged at the inner side of the sealing ring body opposite to the arc plate, and a plurality of annular extrusion protrusions are arranged in the groove part.

[0011] Further, the extrusion pieces and the arc plate are spliced into a circle.

[0012] Beneficial effects

[0013] Compared with the prior art, the utility model has the following beneficial effects: through extruding the water pipe end part, the rubber material pressure receiving part fills the uneven part of the water pipe end surface, so that the two water pipes are not provided with a gap, the sealing effect is better, and the pressure between the water pipe end surface and the pressure receiving part is further increased by combining the extrusion piece, the sealing property is further improved; in addition, a plurality of extrusion protrusions are arranged, and the plurality of extrusion protrusions can realize the multi-sealing of the pipe outside in cooperation with the hoop.
