作用させることができる。In the type of coupling means shown in FIG. It can be inserted from the end 4 side, the annular protrusion of the cap nut comes into contact with the annular protrusion of the inner end 9, and the nut can be easily screwed into the male thread 8 of the inner end 7 of one tube body 1. . However, if the outer end 4 of the tube body 2 is larger than the inner end 9 as shown in FIG.
Since the cap nut 11 cannot be inserted from the outer end 4, the inner end 9
However, in order to insert the cap nut 11 from the inner end 9, the inner diameter of the annular protrusion 13 of the cap nut 11 is smaller than the outer diameter of the annular protrusion 10 of the inner end 9 of the tube body 2. It has to be bigger. Then, bag nuts ll
Since the rear surface of the annular protrusion 13 of the tube body 2 no longer comes into contact with the inner surface of the annular protrusion 13 of the inner end 9 of the tube body 2, an elastic ring 14 with both ends open is interposed between these annular protrusions 10 and 13. let In practice, this elastic ring 14 can be mounted in front of the annular projection 13 of the cap nut 11 and can act as an abutment part for the cap nut 11 against the rear surface of the annular projection 10 of the inner end 9.

However, by inserting this into the hole of the cap nut 11 with its diameter reduced and then releasing it, the elastic ring 14 can be attached in front of the annular protrusion 13 of the cap nut. Of course, the outer diameter of the annular projection 10 on the inner end 9 of the other tube body 2 must be smaller than the inner diameter of the internal thread 12 of the cap nut 11. Note that a packing 15 is arranged between the abutting surfaces of both tube bodies 1 and 2 for sealing.

較的大径の管に用いられる。In the embodiment shown in FIG. 1, a connecting means having a cap nut 11 is used as the connecting means for connecting the inner ends of the tube bodies without rotating the tubes to be connected, but as an alternative example, two An integral elastic ring that spans the ends of the pipe bodies is attached to the pipes to be connected, and the upper part is surrounded by a two-split joint body that has a circumferential groove on the inner surface, and the inner peripheral edges of the two pipe ends are attached on both sides. It is also possible to use a so-called Victoria joint that fits into a circumferential groove. As a connecting means, the cap nut type is used for relatively small diameter pipes, and the Victoria type is used for relatively large diameter pipes.
