Claims

[Claims for Utility Model Registration] 1. A joint body 3 having a cylindrical portion 5 expanded on the inner circumferential side and an inclined surface 6 connected to the cylindrical portion 5, and a male thread 15 formed on the outer periphery of the end of the joint body 3. A space having a wedge-shaped cross section formed by a cap nut 4 having a female thread 16 at one end and an inclined surface 13 on the inner circumference of the other end, the cylindrical portion 5 and inclined surface 6 of the joint body, and the outer circumferential surface of the connecting pipe 20. An annular packing 7 to be filled, a washer 8 facing the annular packing, and an inclined surface 1 of the cap nut.
3, the retainer 10 has an inclined surface 14 and presses the biting ring 9 to fit it into the annular groove 21 of the connecting pipe, a rubber ring A11, and a rubber ring B12, and the cap nut 4 is screwed into the joint body 3. A telescopic flexible joint for stainless steel water pipes that, when tightened, seals and holds a connecting pipe 20 in a joint body 3 by the action of an annular packing 7 and a bite ring 9, and prevents the connecting pipe from coming off. A retaining ring for a telescopic flexible joint, characterized in that a bite ring 9 and a retainer 10 are integrated. 2 The retaining ring 1 is attached to the inclined surface 13 of the cap nut.
It consists of an annular body 2 having an inclined surface 2a that comes into contact with the cap nut, and whose outer diameter is larger than the inner diameter of the inclined surface 13 of the cap nut. A side wall 2b is formed to be slightly larger than the outer diameter d of the nut, and the retaining ring 1 is pressed by the inclined surface 13 of the nut, and its diameter is reduced so that the tip of the side wall 2b fits into the annular groove of the connecting pipe. 2
1. A retaining ring for a telescopic flexible joint according to claim 1 of the patented utility model, characterized in that the retaining ring is fitted into a telescopic joint.
