In FIG. 6, the same code | symbol is attached | subjected about the conventional code | symbol, and the duplication description is abbreviate | omitted.

First, the packing rings 30a and 30b are fitted to the ends of the pipes while the bushings 50a and 50b and the holder 100 are sequentially inserted into two pipes P1 and P2 to be connected.

Next, when the pipes P1 and P2 are inserted into the joints 10 at both side connecting portions 20a and 20b while the joint body 10 is positioned between the pipes P1 and P2, the pipes P1 and P2. The tip and the packing rings 30a and 30b are inserted into the first holes 22a and 22b and the second holes 24a and 24b inside the connecting portions 20a and 20b, respectively. At this time, the narrow portions 32a and 32b of the packing rings 30a and 30b are not excessively inserted due to the steps 23a and 23b between the first holes 22a and 22b and the second holes 24a and 24b. The pipes P1 and P2 are caught by the central jaw 14 of the body 10.

Holding the hexagonal head 12 and turning the bushings 50a and 50b so that the joint body 10 does not rotate in this state, the female threads 54a and 54b of the bushings 50a and 50b are formed in the joint body 10. It is inserted inward while screwed into the male screw portions 16a and 16b.

At the same time, the holder 100 fitted to the front of the bushings 50a and 50b comes into contact with the tip ends of the extensions 34a and 34b of the packing rings 30a and 30b.

As the bushings 50a and 50b are continuously rotated, the tip ends of the inclined portions 56a and 56b of the bushings 50a and 50b are pressed while pressing the ends of the protruding indentation vanes 120 of the holder 100, and thus the holders. The main body 110 of the 100 pushes the extended portions 34a and 34b of the packing rings 30a and 30b, and the second holes 24a and 24b of the connecting portions 20a and 20b of the packing rings 30a and 30b. The wedge effect on the pipes (P1, P2) allows airtightness and leakage prevention.

In addition, in the holder 100 which is in direct contact with the bushings 50a and 50b, the protruding press-in blade 120 on one side thereof is contacted / pressurized with the tip ends of the inclined portions 56a and 56b inside the bushings 50a and 50b. , Between the indentation wing 120 and the indentation wing 120 is cut so that the diameter is contracted to firmly hold the pipe (P1, P2).

At this time, since the indentation wing 120 is easily contracted by the elastic bent portion 140 formed between the indentation wing 120 and the main body 110, the bushings 50a and 50b can be rotated even with a small force. .

In addition, since the wear protection ring 160 is located on the upper surface of the elastic bending portion 140 when the bushings 50a and 50b are rotated, uniform pressure may be applied while the bushings 50a and 50b are smoothly rotated. 50a and 50b may be prevented from being mowed by the elastic bent portion 140.

In addition, due to the contraction of the indentation blade 120, the fixed projection 130 having a strong hardness due to the difference in hardness between the fixing projection 130 and the pipes P1 and P2 is spot-shaped on the outer surface of the pipes P1 and P2. Since pressing is performed while forming a point pressed inwards, separation of the pipes P1 and P2 is prevented.

On the other hand, when rotating the bushing (50a, 50b), the index blade 150 presses the packing ring (30a, 30b) with a greater force to prevent the leakage occurs.

In addition, the holder 110 is prevented from excessive insertion by the elastic bending portion 140 is caught on the ends of the connecting portion (20a, 20b).

The present invention may be variously modified and may take various forms, and the detailed description of the present invention has been described only with respect to specific embodiments thereof. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
