は上記した弧状曲面5の半径rの2倍に等しい。 First, this pipe material connecting device 1 is capable of bending by changing the axial direction of connected adjacent pipe materials 2. The tube material 2 has a short tube structure with an enlarged diameter portion 4 formed at one end of the straight tube portion 3 and an outer flange portion 6 formed at the other end. The inner circumferential surface of the enlarged diameter portion 4 has a width W of the enlarged diameter portion 4 on the axis l.
An arcuate curved surface 5 having a radius r centered on a center point O set approximately at the center of is formed. On the other hand, the flange portion 6 has an outer flange shape with an outer diameter φ' and is open in the shape of a flap, and a ring-shaped packing 7 is provided on the periphery of the flange portion 6 to make elastic contact with the inner circumferential surface of the enlarged diameter portion of the adjacent tube material 2. It has been established. The outer diameter of the packing 7 is φ
is equal to twice the radius r of the arcuate curved surface 5 described above.

てしまうこともない。 In addition, when the pipe material is bent as described above, since the flange part 6 has an outer flange shape that is opened in a flap shape with respect to the straight pipe part 3, the cable 11 such as a power line passing through the inside of the flange part 6 is
is not bent sharply. Furthermore, when the bending angle of adjacent tube materials exceeds a certain level, the end edge 4a of the enlarged diameter portion 4 comes into contact with the outer surface of the straight tube portion 3 of the adjacent tube material and acts as a stopper. Therefore, the bending angle of adjacent pipe materials can be appropriately limited, and the cable 11 will not be bent beyond the permissible radius of curvature, which may cause the cable 11 to be damaged at the bend or the electrical characteristics to deteriorate. There is no. Further, due to the above-described action as a stopper, the flange portions 6 of adjacent tube members 2 do not come off from the enlarged diameter portion 4.

する。 Straight pipe section 3 to maintain the bent state of the pipe material.
The enlarged diameter ring 12, which is inserted into a position close to the flange portion 6, is a narrow metal ring having a substantially C-shape with a split. The enlarged diameter ring 12 has one end inserted into the gap formed by the inner periphery of the enlarged diameter part 4 of the adjacent pipe material and the outer periphery of the straight pipe part 3 located in the enlarged diameter part 4. On the outer periphery of the protruding end, an outward stepped protrusion 13 that can engage with the inner circumferential surface of the open end of the enlarged diameter portion 4 of the adjacent tube 2 is provided along the axis of the adjacent tube. It is formed continuously so as to be located on a circular arc line centered at l. As is clear from FIG. 3, the stepped protrusion 13 is formed on the outside of the bent portion when the tubes 2 are connected to each other in a bent shape, that is, on the inner periphery of the enlarged diameter portion 4 of the adjacent tubes 2. The height of the central portion 13a, which is located at the point where the gap formed by the outer circumference of the straight pipe portion 3 of the pipe material 2 that protrudes into the enlarged diameter portion 4 is the widest, is the highest, and from here the left and right ends The height is gradually reduced as it approaches the portion 13b. With the above configuration, even if the bending angle at the connecting portion of the pipe material is large and the interval formed inside the bent part is extremely narrow, the stepped protrusion 13 This has the advantage that the end portion of the enlarged diameter ring 12 formed with the diaphragm ring 12 can be inserted easily.

A wing screw 14 having a thumb screw 14 is screwed together.
Therefore, the enlarged diameter ring 12 is positioned on the straight pipe portion 3 of the pipe material by turning the thumbscrew 14 in the tightening direction. Further, when the thumbscrew 14 is further turned in the tightening direction, the diameter expanding ring 12 gradually widens the split and expands in the diameter outward in the radial direction, and the stepped protrusion 13 formed on the outer periphery of the end thereof expands. It is pressed against the inner peripheral surface of the open end of the diameter portion 4.

In addition, when finely adjusting the bending angle, loosen the thumbscrew 14 to slightly reduce the diameter of the enlarged diameter ring 12, so that the stepped protrusion 13 formed on its outer periphery and the inner circumferential surface of the enlarged diameter portion 4 are adjusted. Disengage. As a result, the tube material is maintained in a bent state only by the packing that comes into elastic contact with the inner circumferential surface of the enlarged diameter portion 4, so that the degree of bending of the tube material can be finely adjusted by applying force. After making fine adjustments, tighten thumbscrew 1 again.
4 to expand the diameter of the diameter expansion ring 12, and the stepped protrusion 13 formed on the outer periphery of the ring 12 is pressed against and engaged with the inner peripheral surface of the diameter expansion part 4.
