Problems solved by technology

However, if a seal made of hard rubber, which is not easily deformed elastically, is used to resist this pulling force, the joint and the straight pipe will not be in close contact, resulting in a problem that high watertightness cannot be ensured.

Embodiment Construction

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0019] In the figure, 1 is a pipe joint for connecting different-shaped pipes made of, for example, synthetic resin as one pipe of the present invention. In this pipe joint 1, an annular protrusion 2 is formed at the central position of the inner peripheral surface, and cylindrical portions 3, 3 are formed at both ends of the pipe joint 1 sandwiching the annular protrusion 2. As shown in FIG. These cylindrical parts 3 , 3 form three diameter-expanding sections along the direction away from the annular protrusion 2 .

[0020] As another pipe of the present invention, the end of a steel straight pipe 4 is inserted into the cylindrical portion 3 on one end side of the pipe joint 1, and the end of a synthetic resin spiral corrugated pipe 5 is inserted into the other end. In the cylindrical part 3 on the side, the two pipes communicate with each other.

Abstract

To provide a pipe connecting structure allowing fully opposing a drawing force while securing a high watertightness. A cylindrical packing for a joint 6 is interposed between a pipe joint 1 and an end part of a straight pipe 4 inserted into a cylindrical part 3 of the pipe joint 1. The packing 6 comprises a soft section 10 for cut-off at a tip part positioning on the inserting end face 7 side of the straight pipe 4 and a hard section 11 for preventing falling to prevent the packing 6 from falling from the pipe joint 1 by engaging with a member 19 for preventing falling fixed on the pipe joint 1 at the rest rear end part.

Description

technical field [0001] The present invention relates to a joint seal ring for pipe connection parts and a pipe connection structure using the joint seal ring. Background technique [0002] At present, when connecting a pipe joint such as a special-shaped pipe joint to a straight pipe, the end of the straight pipe is inserted into the end of the pipe joint, and then the gap between the ends is blocked, and then more is wound. A waterproof tape. However, winding the tape for waterproofing must rely on manual work, requiring a lot of labor and labor time. Furthermore, it is difficult to secure stable water-tightness. [0003] In recent years, instead of wrapping waterproof tape, a sealing ring is installed between the pipe joint and the end of the straight pipe. In this way, the connection work can be completed very easily in a short time, and stable water tightness is ensured. . Contents of the invention [0004] However, as this type of seal, in order to ensure close co...
