Therefore, as shown in FIGS. 7-10, the process of locking the pipe joint 100 and each water pipe 200 is described as follows:

1. As shown in Fig. 7, each positioning bead ring 40 and each water stop ring 30 are assembled into the inner hole 24 of the respective bezel nut 20, and each bead ring 20 and the main pipe 10 Screw lock slightly, and then insert each water pipe 200 through a respective bead nut 20, a respective positioning bead ring 40 and a respective water stop ring 30 into the main pipe 10.

2. As shown in Figures 8 and 9, each bezel nut 20 is further screw-locked with the main pipe 10, so that the push-pull surface 233 of the inner peripheral surface 23 of each bezel nut 20 and the respective positioning beads The pressured outer peripheral edge 412 of the pressure-receiving end 411 of the ring wall 41 of the ring 40 abuts, and the respective positioning bead ring 40 and the respective water stop ring 30 are pushed inward along the axial direction X to the respective stop The water ring 30 abuts against one of the pipe ends 11 of the main pipe 10. During this process, the first slope of the first oblique line 26 (see FIG. 6) is greater than the second slope of the second oblique line 45 (see FIG. 6). Therefore, the pushing-out surface 233 of the inner peripheral surface 23 of each bead ring 20 will only first come into contact with the compressed outer peripheral edge 412 of the pressure-receiving end 411 of the ring wall 41 of the respective positioning bead ring 40. But it will not touch the positioning beads 42 of the respective positioning bead rings 40. In this way, the push-out surface 233 of the inner peripheral surface 23 of each ring nut 20 can be connected to the ring wall 41 of the respective positioning bead ring 40. The pressured outer peripheral edge 412 of the pressured end 411 generates a 360° contact relationship, and the respective positioning bead rings 40 are directed to be aligned with the axial direction X of the main pipe 10.

3. As shown in Figure 10, each bezel nut 20 is completely locked with the main pipe 10. At this time, since the hardness of each bezel nut 20 is greater than that of the ring wall 41 of the respective positioning bead ring 40 The hardness, and each positioning bead ring 40 has been blocked by the respective water stop ring 30, and can no longer move inward along the axial direction X. Therefore, the push-pull face of the inner peripheral surface 23 of each bezel nut 20 233 can force the pressurized outer peripheral edge 412 of the pressurized end 411 of the ring wall 41 of the respective positioning bead ring 40 to produce a chamfer-like deformation, so that the push-pull face of the inner peripheral surface 23 of each ring nut 20 233 can come into contact with the positioning bead 42 of the respective positioning bead ring 40, then when the push-out surface 233 of the inner peripheral surface 23 of each loop nut 20 abuts the positioning bead 42 of the respective positioning bead ring 40 At the time of connection, the compressed outer peripheral edge 412 of the compressed end 411 of the ring wall 41 of each positioning bead ring 40 will also abut the push-out surface 233 of the inner peripheral surface 23 of the respective bead nut 20. At the same time, each water stop ring 30 will also abut the respective pipe end 11, and the ring wall 41 of each positioning bead ring 40 will also abut the respective water stop ring 30. In this case, each The push-pull face 233 of the inner peripheral surface 23 of the ring nut 20 can force the positioning beads 42 of the respective positioning bead rings 40 to inwardly press against the respective water pipes 200, and the respective water pipes 200 can be locked and positioned. .

Through the above description, the advantages of the present invention can be summarized as follows:

1. The design utilizes the first slope of the first oblique line 26 (see Figure 6) of each bead nut 20 to be greater than the second slope of the second oblique line 45 (see Figure 6) of the respective positioning bead ring 40 , So that each ring nut 20 is locked with the main pipe 10 but not completely locked first, only with the compressed outer periphery of the pressure end 411 of the ring wall 41 of the respective positioning bead ring 40 The rim 412 makes contact, but does not touch the positioning bead 42 of the respective positioning bead ring 40. In this way, the pushing surface 233 of the inner peripheral surface 23 of each bezel nut 20 can be contacted with the respective positioning bead. The pressured outer peripheral edge 412 of the pressure-receiving end 411 of the ring wall 41 of the ring 40 produces a 360° contact relationship, and the respective positioning bead rings 40 are surely guided to be aligned with the axial direction X of the main pipe 10.

2. The present invention utilizes the design that the hardness of each ring nut 20 is greater than the hardness of the ring wall 41 of the respective positioning bead ring 40, so that when each ring nut 20 is completely locked with the main pipe 10, The push-pull face 233 of the inner peripheral surface 23 of each bead nut 20 forces the compressed outer peripheral edge 412 of the pressure-receiving end 411 of the ring wall 41 of the respective positioning bead ring 40 to deform, so that each beam The pushing surface 233 of the inner peripheral surface 23 of the ring nut 20 comes into contact with the positioning beads 42 of the respective positioning bead rings 40, thereby forcing the positioning beads 42 of the respective positioning bead rings 40 to move the respective water pipes 200 inward. Definitely click the positioning.

3. In the process of locking each ring nut 20 of the present invention, each positioning bead ring 40 is directly abutted between the respective ring nut 20 and the respective water stop ring 30 In order to prevent each positioning bead ring 40 from being continuously moved inward along the axial direction X of the main pipe 10, compared with the conventional technology, the present invention can completely omit the arrangement of the conventional gasket seat 4, and can simplify the assembly operation. And reduce the overall number of parts, and reduce manufacturing costs.

In summary, the pipe joint of the present invention can not only guide the respective positioning bead rings to be aligned with the axial direction of the main pipe, but also force the positioning beads of the respective positioning bead rings to be different The water pipe can be accurately locked and positioned, and the number of parts can be reduced, and the manufacturing cost can be reduced. Therefore, the purpose of new cost can be achieved.

However, the above-mentioned are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
