なかつた。Conventional technology and its problems Figures 1 and 2 show examples of conventional thin-walled water pipe joints. Loosely fit the ring C, insert the thin-walled tube A into the main body D to an appropriate position, and tighten the nut and main body D with a wrench to compress the ring C and deform the thin-walled tube A to prevent it from coming out. The one shown in the figure inserts a thin-walled tube A into the main body D, compresses the part where the sealing ring rubber hole is installed using a hydraulic machine, and compresses and squeezes the part G into the thin-walled tube D to prevent it from slipping out. However, in any of the embodiments, when the water inside the pipe freezes in a cold region, the pressure acting inside the pipe causes the pipe to come out of the main body, making it impossible to put it into practical use.

A reinforcing cylindrical body for a thin-walled water pipe joint is provided with a flange having an outer diameter approximately equal to the outer diameter of a thin-walled pipe, and when the reinforcing cylindrical body is inserted into the end of the thin-walled pipe, the flange becomes equal to the thin-walled pipe. By being locked to the end of the tube, said end is reinforced. In addition, the annular recess provided on the outer circumferential surface of the cylindrical body is such that when a thin-walled pipe is compressed and narrowed, the narrowed portion is fitted into the annular recess to prevent it from coming off, as in the thin-walled water pipe joint shown in Figures 1 and 2. becomes the resistance.

凹部をＶ状溝２としたものである。 FIG. 3 shows an embodiment of the present invention, in which a reinforcing cylinder 4 provided with a recess 2 and a flange 3 is inserted into the end 1' of the thin-walled tube 1, and A seal rubber 7 for sealing the outer periphery of the thin-walled tube 1 is installed in a joint body 6 provided with a large-diameter cylindrical portion 5, and the end portion 1' of the thin-walled tube 1 is inserted into the cylindrical portion 5 to an appropriate position. , a bolt 8 is attached to the joint body 6. FIG. 4 shows another embodiment of the reinforcing cylinder according to the present invention, in which the annular recess provided in the reinforcing cylinder 4 is a V-shaped groove 2.

It is pressed against the reinforcing cylinder 4 inserted into the thin-walled tube 1. A recess 2 is provided in the reinforcing cylinder 4 and a bolt 8 is provided.
The thin-walled tube deformed by pressure is clamped between the bolt 8 and the recess 2 and fixed. Therefore, even if the water inside the pipe freezes in cold regions and large pressure is generated inside the pipe, the thin-walled pipe 1
is retained without slipping out.

を提供できるものである。 As described above, the reinforcing cylindrical body of the thin-walled water pipe joint of the present invention compresses and narrows the outer periphery of the thin-walled pipe by reinforcing the end of the thin-walled pipe and providing an annular recess on the outer periphery of the cylindrical body. The narrowed part of the thin-walled water pipe joint fits into the annular recess and is pressure-welded, which prevents the pipe from slipping out of the joint due to freezing inside the pipe, which was the biggest drawback especially in cold regions, and is inexpensive and has a simple structure. It is possible to provide a simple reinforcing cylindrical body for thin-walled water pipe joints.
