[Example] Examples of the water faucet/gas faucet joint according to the present invention are shown in Figs.
and FIG. 3, and will first be described based on FIG. 1. In FIG. 1, the area above the center line is a sectional view, and the area below this is a front view.

The faucet/gas faucet joint of this embodiment is installed between the inner wall plate 20 on the indoor side and the outer wall plate 30 on the outside, and holes are formed at the mounting positions of the faucet/gas faucet joints on the inner wall plate 20. Open 21 and fix it here. This wall panel is made of, for example, wooden plywood, plasterboard or plastic board. In Figure 1, the flow direction of the water faucet/gas faucet joint is 90''.
There is also an elbow type that changes, but a socket type that does not change the flow direction.

The plug joint body 1 has a hollow cylindrical shape and an elbow type, and one end has a structure for connecting a flexible pipe, the other end has a thread 14 on the outer peripheral surface, and a plug joint part on the inner peripheral surface. That is, a female thread 13 for a faucet/gas faucet is formed.

The flexible tube connected to this one end is, for example, a plastic tube or a bellows-type flexible metal tube, and is the plastic tube 6 in this embodiment.

The structure and portion of one end of the plug joint body 1 for connecting the plastic pipe 6 are as follows.

That is, one end of the plug joint main body 1 is a double cylinder, and the plastic pipe 6 is fitted into the inner cylindrical part 11, and the nut is screwed into the outer cylindrical part 12. The inner cylindrical portion 11 has an inner circumferential surface that has the same inner diameter as the inner circumferential surface of the middle portion of the plug joint body 1, and a jagged part is formed on this outer circumferential surface to which the plastic pipe 6 fits and prevents its removal. be.

The end of this plastic pipe 6, that is, the plug joint body 1,
An annular lock ring 3 is attached to a portion of one end that fits into the inner cylindrical portion 11.

The outer cylindrical portion 12 at one end of the plug joint body 1 has a thread formed on its outer circumferential surface, and its inner circumferential surface is a tapered inner circumferential surface that becomes rounded and has a larger diameter toward the outside. A nut 2 is screwed onto this male thread on the outer peripheral surface. The nut 2 has a female thread on its inner circumferential surface and a collar at the end of its inner circumferential surface. When this nut 2 is screwed to the plug joint body 1 and the outer cylindrical portion 12 at one end, the brim of the nut 2 pushes the end surface of the lock ring 3, and the lock ring 3 presses against the outer peripheral surface of the plastic pipe 6.

A resin cover is further attached to the outer peripheral surface of the nut 2 and also covers the plastic pipe 6.

One end of the plug joint body 1 explained above and the lock ring 3
and the nut 2 constitute a pipe joint portion of the plastic pipe 6.

First, the flange 4 is screwed to the external thread 14 formed on the outer peripheral surface of the other end of the plug joint body 1. The flange 4 is a rectangular plate-shaped flange 4 as shown in FIGS. 2A and 2B, or a plate-shaped flange 4 whose short side is an arc.

Each flange 4 has a longitudinal length longer than the diameter of the hole 21 of the inner wall plate 20, and a width direction perpendicular to the longitudinal direction shorter than the diameter of the hole 21. The flange 4 has a through-hole female screw hole 41 in the center thereof which is screwed to the plug joint body 1 and the male screw 14 at the other end. Flange 4 is the second
As shown in a%b in the figure, it may be a normal plate shape, but the first
As shown in the figure, the surface of the flange 4 on the inner wall plate 20 side may be a stepped surface so that the spigot can be fitted. In this way, the center of the hole 21 in the inner wall plate 20 and the plug joint body 1
The center of the other end does not deviate significantly. A blind hole 42 is bored in the vicinity of the female threaded hole 41 approximately on the center line in the longitudinal direction of the flange 4, and this blind hole 42 is a blind hole into which a tool is inserted to rotate the flange.

The flange 4 described above has a female threaded hole 41 and is threadedly connected to the plug joint body 1 and the male thread 14 at the other end, but these may be integrated.

The flange 4 is threadedly connected to the male thread 14 at the other end of the plug joint main body 1, but in order to prevent the flange 4 from coming off from the male thread 14 to the middle part of the plug joint main body 1, It is preferable to form a stopper 15 on the outer circumferential surface.

After the flange 4 is screwed to the male thread 141 at the other end of the plug joint body 1, the flange type nut 5 is screwed to the male thread 14. That is, the flange 4 is screwed to the other end on the intermediate side of the plug joint body 1, and the flange type nut 5 is screwed to the other end on the end side.

As shown in FIG. 3, the flange type nut 5 has a circular ring shape and has a female threaded hole 51 in the center thereof which is threadedly connected to the male thread 14 at the other end of the plug joint body 1. In addition, as shown in the cross-sectional view of FIG. 4, the flange-type nut 5 has a circumferential groove 8 cut in one surface, the wall-side surface, and a rubber or plastic O-ring is inserted into this groove 8. Embed. Drill blind holes 52 in about four places on the other side of this side, and
Insert a tool into the flange type nut 5, rotate the flange type nut 5, screw it to the other end of the plug joint body 1, and tighten it firmly.

The flange type nut 5 may be rotated by making it into a hexagonal shape, a hexagonal shape, or a shape having two parallel planes, and rotating it with a spanner or the like, instead of making it circular and having a blind hole 52 formed therein. In this case, the blind hole 52 is unnecessary.

Further, in order to increase the axial length of the female threaded hole 51 of the flange-type nut 5, the surface of the flange-type nut 5 on the inner wall plate 20 side may be a stepped surface as shown in FIG.

Next, the method, operation, and order of attaching the water faucet/gas faucet joint of this embodiment described above to the inner wall plate 20 will be explained.

First, before installing the water faucet/gas faucet joint, the inner wall plate 20 and the outer wall plate 30 are already provided, the inner wall plate 20 has a hole 21, and these double walls A plastic pipe 6 and this cover 7 are piped inside to the vicinity of the hole 21.

First, the plastic pipe 6 and its cover 7 are pulled out into the room through the hole 21, and connected to the pipe joint part of the faucet/gas faucet joint as previously described.

Second, the plastic pipe 6 and the pipe joint part of the water faucet/gas faucet joint to which this cover 7 is connected, and the other end of the faucet joint main body 1 with the flange 4 screwed to it, are screwed into a double layer through the hole 21. Insert into the wall. At this time, since the length of the flange 4 in the longitudinal direction is longer than the diameter of the hole 21, the flange 4
It is necessary to make the longitudinal direction of the inner wall plate 20 oblique rather than parallel to the surface of the inner wall plate 20.

Third, with the flange 4 in contact with the outer surface of the inner wall plate 20, insert the male thread 14 at the other end of the faucet/gas faucet joint main body 1 from the inner surface of the inner wall plate 20 toward the indoor side. Make it stand out,
Connect the flange type nut 5 to the male thread 14 at the other end of the plug joint body 1.
The inner wall plate 20 is clamped between the flange-type nut 5 and the flange 4 by screwing them together and further screwing them in with a tool.

Here, the contact surface of the flange 4 with the inner wall plate 20 may be made uneven so that the flange 4 does not rotate.

The installation of the faucet/gas faucet joint to the inner wall plate 20 and the piping to this are completed, and the female thread 13 for the faucet/gas faucet is attached to the indoor side surface of the inner wall plate 20, that is, the indoor wall surface. After this, a water faucet or gas faucet can be screwed in and fixed.

In this case, the water faucet/gas faucet is of a male thread type, and a female thread 13 is provided on the indoor wall surface. However, the faucet
If the gas valve is a female screw type, the male screw must protrude from the interior wall and should be constructed as follows.

That is, only the other end of the faucet joint body 1 is different from the water faucet/gas faucet joint described previously. is just a flow path. The outer circumferential surface of the other end has a male thread for a female water faucet/gas faucet threaded at the endmost part, and a thread 14 is formed next to this. By using such a faucet joint body, the faucet/gas faucet joint can be used even with female faucet/gas faucet screw types.

Next, if the flange 4 is a water faucet/gas faucet joint in which the flange 4 is threadedly connected to the faucet joint body 1, the attachment position of the flange 4 to the faucet joint body 1 can be adjusted. By performing this adjustment, even if the thickness of the inner wall plate 20 changes somewhat, the flange type nut 5 can always be threadedly connected to the plug joint body 1, and furthermore, the surface of the flange type nut 5 and the plug joint body 1 can be The side end surfaces can be aligned.

The above explanation is about piping and installation of faucet/gas faucet joints, but all the faucet/gas faucet joints of this example can be installed by performing the reverse operation/order/procedure as explained above. It is also possible to remove the attached water faucet/gas faucet joints.

[Effects of the Invention] As explained above, the water faucet/gas faucet joint according to the present invention has the following effects:
Even after installing a 2ffl wall, piping and installation are possible without destroying the wall or making larger holes than necessary.
