を有するものであつた。 As shown in FIG. 6, the conventional connection end fitting has assembly holes 12 and 12' concentrically extending through the shaft core portion and communicating with the internal annular groove passage 19, and the assembly holes 12 and , 12' are made into parallel flat seating surfaces 13, 13', and furthermore, the peripheral side wall part has a connecting hole 14 with the pipe end communicating with the inside, or the seventh As shown in the figure, a cylindrical wall 14' having a connecting hole with the end of the piping is provided on the circumferential wall and integrally protrudes toward the main body. Therefore, in the former case, only the wall thickness of the peripheral side wall and the end of the pipe are connected by soldering, which results in poor welding strength, resulting in uneven bending of the pipe side, forced installation in the event of a malfunction, or vibration. When used under such conditions, there is a problem in that the concentration of fatigue stress causes cracks and breakage on the piping side of the welded part. Due to the structure, the weight of the product increases, and the cutting and forming process as a whole becomes extremely complicated, increasing the number of machining operations and significantly reducing productivity.

きるものである。 The purpose of the present invention is to provide an end fitting for connecting the end of a small diameter metal pipe, which solves the above-mentioned problems extremely simply and effectively. The engagement hole of a reinforcing beam member having an L-shaped cross section, which is a separate member with a partially cut-out support hole, is concentrically welded to the assembly hole of the end fitting body,
In addition, the vicinity of the end of the pipe is welded to the brazing hole and the support hole or circular support hole of the end fitting body, and the reinforcing beam member can be easily formed by press working from a metal plate, and is This not only improves productivity and allows manufacturing at low cost without significantly affecting the weight of the product, but also because the solder welding hole and support hole or round support hole are each welded to the end of the pipe. It can improve strength.

The end fitting main body has the peripheral end surfaces 3 and 3' of the holes as parallel flat seating surfaces, and a hole 4 for soldering in the peripheral side wall.It is easy to cut, for example, into circular slices from a pipe material. It can be molded into On the other hand, the reinforcing beam member 5 formed by press-molding a metal plate material has an engagement hole 6 which is smaller in diameter than the assembly hole 2 and can be fitted into the assembly hole, and an insertion support hole near the end of the pipe P. 7. It has an L-shaped cross section and is a separate body having a circular support hole 7', and an engagement hole 6 and a support hole 7 on the reinforcing beam member side.
are located concentrically with the assembly hole 2 and the brazed welding hole 4 on the side of the end fitting main body 1, respectively, and the brazed welding hole 4 part, the support hole 7 part, or the missing circular support hole 7' part. It is constructed by fixing it by welding 8 to one peripheral end surface 3 of the assembly hole 2 on the side of the end fitting main body 1 with an arbitrary distance maintained between the opposing surfaces of the fittings. The engagement hole 6 on the reinforcing beam member 5 side and the assembly hole 2 are attached to one of the hole circumferential end surfaces 3 by making the inner diameter of the engagement hole 6 smaller than the hole diameter of the assembly hole 2 on the end fitting body side and overlapping them. Alternatively, as shown in FIG. 3, the circumferential end of the engagement hole 6 may be slightly bent inward, and the bent portion may be fitted into the circumferential wall of the assembly hole 2. In any case, by soldering these holes 6 and 4, a flow passage 9 is formed with a gap between the inner circumferential surface of the end fitting body and the mounting bolt. Note that 8' and 8'' are solder welded parts.

できるものである。 As described above, according to the present invention, the reinforcing beam member 5, which is separate from the end fitting main body 1 side, is fixed to one of the assembly holes 2, so that when forming the end fitting main body 1 side, It can be easily formed by using pipe materials, and the reinforcing beam member 5 can also be easily formed by press working with metal plate materials, which significantly improves productivity and reduces the weight of the product. A braze welding fixing structure that spans two locations with the support hole 7 part or the missing circular support hole 7' on the reinforcing beam member 5 side, which maintains a gap with the weld weld hole 4 on the end fitting main body side without affecting the This results in sufficient solder welding strength with the end of the pipe P, and therefore
This can prevent and reduce the occurrence of cracks and breakage on the piping side of the welded portion, even if there are variations in the side bending shape, forceful installation in the event of a malfunction, or under vibration conditions.
