Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1 to 4, an embodiment of the present application provides a novel rubber seal ring, which includes an annular rubber ring body 11; the inner ring surface of the rubber ring body 11 is obliquely arranged along the axial direction of the rubber ring body 11 to form a connecting inclined surface 12, so that the bell and spigot pipelines are connected more easily; the end of the rubber ring body 11 with smaller thickness along the axial direction is a connection front end 13, and the end of the rubber ring body 11 with larger thickness along the axial direction is a connection rear end 14;

a reinforcing sealing mechanism 15 is arranged on the end face of the connecting rear end 14 along the annular direction, and when the rubber sealing ring is installed, the reinforcing sealing mechanism 15 faces to one side of water flow in the pipeline; the reinforced sealing mechanism 15 comprises a V-shaped ring groove 51 which is arranged on the end surface of the jointed rear end along the circumferential direction; the V-shaped ring groove 51 can be slidably inserted with a support ring 52, and water flow in the pipeline extrudes the support ring 52 to support the V-shaped ring groove 51, so that the rubber sealing ring is more tightly attached to the pipeline; a plurality of fixing ropes 53 are uniformly arranged on the outer end surface of the support ring 52 along the circumferential direction, and the support ring 52 is fixed in the V-shaped ring groove 51; the two ends of the fixing rope 53 are fixed to the rubber ring body 11 at the inner side and the outer side of the supporting ring 52 by fixing nails 54.

In a preferred embodiment, the end surface of the engaging rear end 14 is inclined inward from the outer annular surface of the rubber ring body 11 to the inner annular surface of the rubber ring body 11. After the installed sealing rubber ring is extruded by the insertion pipe in the bearing port, the rear end 14 is connected to form a vertical sealing end face, and the sealing effect is better.

In a preferred embodiment, a receiving chamfer 16 is provided at the corner between the engagement bevel 12 and the engagement front end 13. The connection and installation of the socket and spigot pipeline for installing the rubber sealing ring are smoother by the arrangement of the bearing chamfer 16, and meanwhile, the overall structural strength of the rubber sealing ring cannot be influenced.

In a preferred embodiment, the fixing pin 54 includes a fixing rod 541 having one end extending into the rubber ring body 11; the end part of the fixing rod 54 extending into the rubber ring body 11 is integrally provided with a fixing sheet 542; the end part of the fixing rod 54 far away from the rubber ring body 11 is integrally provided with a fixing ring 543; the fixing string 53 is fixed through the fixing ring 54.

In a preferred embodiment, the securing cord 53 is an elastic cord. The fixing cord 53 can elastically fix the stay ring 52, and does not break due to over-tightening of the stay ring 52.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept.
