が十分に発揮されないという欠点がある。 However, in recent years, as residential buildings have become higher-rise, fire-resistant structures have been required, and sanitary bends made of vinyl chloride cannot meet the fire-resistant structure requirements, so sanitary bends made of cast iron are being used. It is being considered to do so. However, when using a sanitary bend made of cast iron, the sealing effect is not sufficient because conventional rubber packing cannot support the weight of the sanitary bend, and the surface of the cast iron is poorer than that of a sanitary bend made of vinyl chloride. It has the disadvantage of not being fully utilized.

るという効果がある。(5) Effects of the invention Since this invention consists of the above-mentioned structure,
The packing 1 interposed between the tube insertion port and the tube socket includes a small annular projection 10 and a large annular projection 1 that are pressed against the inner circumferential surface of the tube portion 14 in relation to the tube socket.
1 to the inner circumferential surface of the cylindrical portion 14, thereby preventing water leakage between the pipe socket and the packing.On the other hand, in relation to the pipe socket, the pressure contact force causes the small annular protrusion 10 to The adjacent large annular protrusion 11 cooperates to press the tapered surface 12 of the annular part 12 against the inner peripheral surface of the cylindrical body 6, thereby enclosing the annular part 12. This makes it possible to prevent water leakage between the pipe inlet and the packing 1. Therefore, the above-mentioned pipe joint can be applied to, for example, the sanitary bend and the outlet of the toilet bowl, and if the sanitary bend is made of cast iron, it can be ensured. A good sealing effect can be ensured. Moreover, when making the above connection, the cylindrical body 6 of the packing 1 has a push-open cylindrical part 9, and since it is fitted into the annular part 12 of the pipe insertion port from the open end side of this expandable cylindrical part, the installation work is easy. In addition to being easy, since no large or small annular protrusions are required on the inner circumferential surface of the cylindrical body 6, molding is easy and manufacturing costs can be kept low. In addition, when a bending action occurs between the pipe socket and the pipe insertion port in the connected state, the large annular protrusion 11 of the packing presses against the inner circumferential surface on the open end side of the cylindrical part 14 in the pipe socket.
This has the effect of absorbing the bending and preventing the joint from breaking.

The outer diameters of the tubes 10 and 11 (only the outer diameter of the small annular protrusion 10 is given the dimension d 3 as shown in FIG. 3) are both larger than the inner diameter D 3 of the cylindrical portion 14. Further, the large and small annular protrusions 10 and 11 come into contact with each other when the cylindrical body 6 is fitted into the discharge port 3 and the discharge port 3 and the sanitary bend 4 are connected. I've learned not to.

3, the small annular protrusion 10 moves along the cylindrical portion 14 of the sanitary bend 4, is pressed against the inner circumferential surface of the sanitary bend 4, and is elastically deformed and press-contacted therewith. When the sanitary bend 4 is fitted, the annular collar 7 is locked to the annular part 12 as described above, so the annular part 12 is prevented from being damaged and the packing 1 itself is prevented from moving. Prevented. In this state, the small annular protrusion 10 forms a wedge between the annular portion 12 of the discharge port 3 and the cylindrical portion 14 of the sanitary bend 4, and is strongly pressed against both the annular portion 12 and the sanitary bend 4. Similarly, the large annular protrusion 11 is also pressed against the inner circumferential surface of the cylindrical portion 14 of the sanitary bend 4, and is elastically deformed and pressed against it.

This ensures that water leakage between the Further, by press-contacting the large and small annular projections 10 and 11 with the cylindrical portion 14, water leakage through the space between the cylindrical portion 14 and the packing 1 is reliably prevented. Further, the adjacent annular protrusions 10 and 11 do not come into contact with each other, and movement of waste water due to surface tension is prevented. Furthermore, the large and small annular protrusions 10 and 11 absorb dimensional tolerances occurring between the discharge port 3 and the sanitary bend 4.
