Example 1.

First, one side of the pipe 40 located at the beginning of the connecting pipe enters the pipe connecting port 16 formed in the connecting pipe 11 of the first connecting pipe 10 to connect the first connecting pipe 10. The pipe support 14 is formed on the inner side of the portion where the jaw 12 and the connection pipe 11 contact. The width of the pipe support 14 must match the thickness of the cross-sectional area of the straight pipe 40, so as not to interfere with the flow of the fluid moving inside the pipe. The cross-sectional thickness of the connection pipe 11 is configured to be equal to or slightly larger than the cross-sectional thickness of the straight pipe 40, so as to prevent a factor of lowering the strength of the connection portion between the pipe 40 and the first connection pipe 10. As a result, the coupling between the pipe 40 and the first connecting pipe 10 is performed.

The connecting jaw 12, which is a portion where the first connecting pipe 10 and the curved pipe 20 are coupled to each other, is formed at an upper end of the connecting pipe 11, and the thickness of the connecting jaw 12 is defined as that of the connecting pipe 11.

The center tube 22 is formed into a shape having a bending of various unit angles. The range of angle can vary from 10 to 30 degrees. In the case where the curved tube 20 is composed of a plurality, the angle change can be made by multiplying the unit angle by the quantity of the curved tube 20, so that the elbow tube can be configured at various angles. The above-mentioned binding member 25 is arranged in the same shape as the above-mentioned binding member 13 at a plurality of equal intervals on the upper peripheral edge of the curved tube jaw 23. The binding member 25 is coupled in the same manner as the coupling method of the binding projection member 21 and the above-mentioned binding member 13 and the binding projection member 21 of the other curved tube 20.

As described above, the curved tube 20 of the last stage should be connected to the second connecting tube 30 in a state in which the plurality of curved tubes 20 are connected.

The thickness of is configured to be at least 1/2 or more of the thickness of the connecting pipe 35 to form the outside of the second connecting pipe 30, so that the bonding strength of the fastening site is not lowered. Fastening jaw 31 is provided with a hollow portion 33, it is connected to the pipe connection port 34 constituting the interior of the connection pipe 35 that is outside of the second connection pipe 30 is configured to smooth the movement of the fluid do. The binding member 25 formed in the curved tube jaw 23 is mutually fastened with the binding protrusion member 32 formed at the lower end of the inner circumference of the fastening jaw 31 of the second connection pipe 30 and the curved tube 20. Joining of the second connecting pipe 30 is made.

The straight pipe 40 starts to enter the pipe connection hole 34 formed in the connection pipe 35 of the second connection pipe 30, and is located on the inner surface of the junction between the connection pipe 35 and the fastening jaw 31. It reaches the support part 36 and the engagement with the 2nd connection pipe 30 is made. As a result, the entire elbow pipe 100 and the straight pipe 40 form a perfect coupling state.

Example 2.

In the present embodiment, instead of the structure of the binding members 13 and 25 mentioned in the first embodiment, the connection member formed of the groove of the recessed shape in the surface in which the binding member is formed is connected to the first connection pipe 10. The configuration of the curved tube jaw 23 formed in the jaw 12 and the curved tube 20 will be described.

Thus, the left and right sides of the V-shaped seating portions 13-9 and 25-9 pass through the entry portions 13-8 and 25-8 formed in the center of the binding members 13 and 25 to serve as passages. It is configured to be seated in either direction. The role of the guide parts 13-7 and 25-7 is to make the binding protrusions 21 and 32 more easily have access to grooves between the binding members 13 and 25. In addition, it characterized in that the inner surface of the guide portion (13-7, 25-7) has a constant inclination angle so that the binding projection members (21, 32) can be more naturally bound to the binding members (13, 25).
