Claims

[Claims for Utility Model Registration] 1. A joint main body 1 having a concave spherical surface portion 4 on the inner peripheral surface, and a convex spherical surface portion 12 that fits into the concave spherical surface portion 4 of the joint body 1 so as to be spherically slidable are integrated. Or a swingable pipe joint consisting of a joint pipe 11 formed separately, which includes an inner circumferential surface 6 extending toward the distal end side of the joint body 1 from the concave spherical surface portion 4 of the joint body 1; It is provided with a stopper 15 for preventing the joint pipe from coming off, which is removably inserted into a gap 16 formed between the convex spherical part 12 of the joint pipe 11 and the outer circumferential surface 17. A swingable pipe joint characterized in that a plurality of stoppers 15 are arranged in a ring shape in a gap 16 and formed in the shape of a small piece that can be inserted. 2. In the swingable pipe joint according to claim 1, the inner circumferential surface 6 of the joint body 1 is provided with a stopper 15 inserted in the gap 16 to prevent the stopper 15 from coming off from the joint body 1. An annular recessed groove 8 into which the outer surface 15b of the stopper 15 is fitted to allow the stopper 15 to slide along the circumferential direction of the gap 16.
is provided, and a front wall portion 10 of the joint body 1 is provided.
In order to insert the stopper 15 into the gap 16 by inserting the outer surface 15b of the stopper 15 into the annular groove 8 from the outside of the joint body 1, a notch 9 is provided for inserting the stopper. A swingable pipe joint characterized in that it is provided in communication with the groove 8. 3. In the swingable pipe joint according to claim 1 or 2, the inner surface 18 of the stopper 15 is formed as a tapered surface that makes point contact with the convex spherical surface portion 12 of the joint pipe 11. Features a swingable pipe joint.
