Description

Sealing rubber ring and inspection hole thereof

Technical Field

The utility model belongs to the field of pipe bodies, and particularly relates to a sealing rubber ring and an inspection opening thereof.

Background

In drainage systems, a large number of inspection ports are often involved, and these inspection ports are generally formed by a pipe body and an end cover of the drainage system, and a sealing ring needs to be arranged between the pipe body and the end cover for sealing so as to ensure the tightness of the connection between the pipe body and the end cover. However, the conventional sealing ring mostly adopts a rectangular sealing ring, and the sealing effect is not ideal, but the reason is that the pipe body and the connected end cover are both made of plastic materials, the flatness of the sealing plane is difficult to control, certain deformation exists, and in the process of screwing the end cover, the end cover is not favorable for screwing operation of the end cover due to large friction force between the sealing plane and the sealing ring body. For the above reasons, a water leakage phenomenon is likely to occur between the pipe body and the end cap of the drainage system.

Example 1

The utility model provides a sealing rubber ring, is including the annular circle body that is located end cover 9 and body 10 hookup location department, the lateral surface that the annular circle body includes the medial surface, the sealed anchor ring of body 8, body loading end 2 constitution of the top surface that circle body top inclined plane 7 constitutes, bottom surface, the inside surface that end cover seal anchor ring 6 constitutes of accepting portion bottom inclined plane 4 and circle body bottom inclined plane 11 constitution, wherein circle body top inclined plane 7 is inclined to the top of end cover seal anchor ring 6 by the top of body seal anchor ring 8, body loading end 2 is the outside convex body accepting portion 3's of annular circle body lateral surface top, and the longitudinal section of body accepting portion 3 is the rectangle, and is the ring body with the coaxial setting of annular circle body. An obtuse angle is formed between the pipe body bearing surface 2 and the pipe body sealing ring surface 8, and a pipe body fitting end 1 is formed between the pipe body sealing ring surface 8 and the ring body top inclined surface 7; the bearing part bottom surface 4 is the bottom end of the pipe body bearing part 3, an obtuse angle is formed between the bearing part bottom surface 4 and the ring body bottom inclined surface 11, and the end cover attaching end 5 is formed at the connecting position of the ring body bottom inclined surface 11 and the end cover sealing ring surface 6.

Example 2

The utility model provides an install in embodiment 1 inspection hole of sealing rubber ring, including end cover 9 and body 10, body 10 passes through threaded connection with end cover 9, the central axis department of end cover 9 has to the inside convex end cover bulge of body 10, the lateral surface and the laminating of end cover sealed torus 6 of end cover bulge, the terminal surface and the laminating of body loading face 2 of body 10, ring body top inclined plane 7 is just forcing the laminating of the inner wall of body sealed torus 8 and body 10 after bearing water pressure towards the inside of body 10, body laminating end 1 pastes the inner wall in body 10 closely. Enough clearance is left between the bottom surface 4 of the bearing part, the inclined plane 11 of the bottom of the ring body and the end surface of the end cover 9, and the attaching end 5 of the end cover is close to the end surface of the end cover 9. The structure and connection relationship of the rest parts are the same as those described in any of the foregoing embodiments, and are not described herein again to avoid the tedious text.

On the basis of the above embodiments, the present invention continues to describe the technical features and functions of the technical features in the present invention in detail to help those skilled in the art fully understand the technical solutions of the present invention and reproduce them.

An internal thread structure matched with the external thread of the outer wall of the pipe body 10 is processed on the inner wall of the end cover 9, an end cover protruding part protruding into the pipe body 10 is arranged on the central axis of the inner end face of the end cover 9, and a distance for installing a sealing rubber ring and matching the end face of the pipe body 10 with the sealing rubber ring is reserved between the outer side face of the end cover protruding part and the inner wall of the end cover 9.

In the utility model, in the process that the end cover 9 is screwed in along the pipe body 10 through the internal threads, because an obtuse angle is formed between the pipe body bearing surface 2 and the pipe body sealing ring surface 8, the screwing operation of the end cover 9 can be effectively ensured, and the increase of friction force caused by the sealing rubber ring in the screwing process is reduced. When the end face of the pipe body 10 contacts with the pipe body bearing face 2 and the end cover 9 is continuously screwed in, the end face of the pipe body 10 applies pressure to the pipe body bearing face 2 to enable the bottom face 4 of the bearing part of the bottom face of the sealing rubber ring and the inclined face 11 of the bottom of the ring body to deform, so that the end cover attaching end 5, the end cover sealing ring face 6 are attached to the end cover protruding part of the end cover 9, and the pipe body sealing ring face 8 is close to the inner wall of the pipe body 10 and attached to the inner wall of the pipe body 10.

When water pressure in the pipe body 10 acts on the ring body top inclined plane 7, the ring body top inclined plane 7 can convert the borne water pressure into deformation of the pipe body joint end 1 and the pipe body sealing ring surface 8 jointed on the inner wall of the pipe body 10, and then closer connection is realized under the action of the water pressure.
