Claims

[Scope of utility model registration request]

In a joint fitting for preventing detachment of a pipe joint part that is attached to a joint part between an inner pipe 1 and an outer pipe 2, a threaded part 3 is formed on the outer peripheral surface or inner peripheral surface of the end of the outer pipe 2, and the threaded part A third presser ring 4 formed with a threaded portion 5 on the inner circumferential surface or the outer circumferential surface that can be screwed into the ring 3.
is fitted onto the inner tube 1 to form a first housing 7 between one wall surface 6 of the first retaining ring 4, the outer circumferential surface of the inner tube 1, and the inner circumferential surface of the outer tube 2. A gasket 8 is mounted inside, and the gasket 8 can be press-sealed by rotating and tightening the first presser ring 4.
A threaded part 10 separate from the threaded part 5 that is threadedly engaged with the outer tube 2 side is formed on the inner circumferential surface of the presser ring 4, and a threaded part 12 that can be threadedly engaged with the threaded part 10 is formed on the outer circumferential surface. A second presser ring 11 is fitted onto the inner tube 1 so that a gap is formed between the tapered inner circumferential surface 13 of the second presser ring 11, the outer circumferential surface of the inner tube 1, and the other wall surface 14 of the second presser ring 4. The second housing 15 is formed and the wedge body 11 is mounted inside the second housing 15, and the second presser ring 11 is rotated and tightened, or the second presser ring 4 is sometimes rotated and tightened by the second presser ring. Ring 11 is the first presser ring 4
A joint fitting for preventing separation of a pipe joint portion, characterized in that the wedge body 17 is brought into pressure contact with the outer circumferential surface of the inner pipe 1 by being drawn to the side.
