Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a gas cock, in particular, a flexible pipe is used as a gas pipe, and the gas pipe is preliminarily laid in an inner space of a wall, a ceiling, or an underfloor. The present invention relates to a gas cock suitable for connecting to.

[Conventional technology]

In a conventional gas cock, as shown in FIG. 6, a gas cock 100 having a pedestal 101 is attached to a flexible gas pipe 1 by using a nut 102, a retainer 103 and a single screw socket 104. That is, for example, the male screw portion 104A (see FIG. 7) of the single screw socket 104 is screwed into the female screw portion formed in the gas cock 100.

[Problems to be solved]

However, in the conventional gas cock, when this gas cock is connected to the gas pipe and attached to the wall W, the gas pipe 1 in the wall W is bent or twisted as shown in FIG. There wasn't.

Therefore, in this invention, when connecting to a gas pipe and mounting it on a wall or the like, the connection and mounting work can be easily performed, and the gas pipe to be connected to the inner space of the wall or the like is unnatural. An object of the present invention is to provide a gas cock that can realize a highly safe piping state without being bent or twisted.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is a gas cock that is connected to a flexible gas pipe laid inside a thin wall or under the floor, and is attached to a partition material such as a wall or floor via a back plate. A pedestal that is formed at the base end of the main body and that cooperates with the back plate to sandwich the partition member, and a rotation that has a sealing property provided in the gas passage near the gas inlet opening on the mounting surface of the pedestal A mechanism and a substantially L-shaped joint that is rotatably attached to the pedestal via this rotating mechanism while maintaining a sealing property, and is configured to connect this joint to the gas pipe. Is.

[Action]

In the present invention, for example, when a gas pipe is installed in a wall, the lower end of the L-shaped joint is connected to the gas pipe when the gas pipe is rising from below. The gas pipe will not be bent or twisted unnaturally. Also, the work of connecting to the gas pipe can be easily performed by rotating the joint.

〔Example〕

A preferred embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a flexible gas pipe 1 is provided inside the wall W.
Is preliminarily piped, a hole 3 (see FIG. 2) is opened in this wall W, and the back plate 2 is set on the back side from this hole 3,
The gas pipe 1 is connected from the hole 3 of the wall W to the extraction joint 4 and the gas pipe 1.

The gas cock 5 has a base 6, and the gas cock 5 is attached to the wall W by sandwiching the wall W between the base 6 and the back plate 2. A gas inlet 7 is formed on the lower surface of the pedestal 6 of the gas cock 5, and the main body (51) near the gas inlet 7 is formed.
A joint 4 is mounted in the internal gas passage (7A) via a rotating mechanism so as to be rotatable and maintain a sealing property.

The O-ring 8 is used for the rotating mechanism used for connecting the L-shaped joint 4 and the gas cock 5, and the stop ring 9 for preventing the joint 4 from coming off is used. Such a rotating mechanism is an example, and various other publicly known means can be adopted as long as the joint 4 is attached so as to be rotatable and maintain the sealing property.

The joint 4 in this invention is formed in an L-shape, a packing insertion hole 10 is formed at the rear end (base end) thereof, and a male screw portion 11 is formed on the outer periphery of the packing insertion hole 10. Further, a copper tightening packing 12 is attached to the tip of the flexible gas pipe 1, and a tightening nut 14 having a female screw portion 13 to be screwed into the male screw portion 11 is provided.

To connect the joint 4 and the gas pipe 1, the tightening packing 12 is inserted into the packing insertion hole 10 and the female screw portion 13 and the male screw portion 11 of the tightening nut 14 are screwed together. Although FIG. 1 shows a state in which the joint 4 and the gas pipe 1 are not connected inside the wall W,
At the time of attachment, as shown in FIG. 2, the gas pipe 1 is pulled out from the hole 3 formed in the wall W, the back plate 2 is inserted into this gas pipe 1, and the back plate 2 is arranged from the hole 3 to the back side of the wall W. . At this time, the wire of the back plate 2
It is possible to prevent the back plate 2 from dropping by pulling 21. In this state, the joint 4 of the gas cock 5 is connected to the gas pipe 1.

Then, as shown in FIG. 3, the long rod 15 having a screw formed at the tip is inserted into the screw hole 61 formed in the pedestal 6 and the tip is screwed into the screw hole 22 of the back plate 2. Long bar 15
While screwing into the screw hole 22 of the back plate 2, the other screw hole 22 and the screw hole 61 are aligned, and the screw 16 is screwed into the screw hole 22 from the screw hole 61. Gas cock 52 at this time
Is guided by the long bar 15 and brought close to the surface of the wall W. Further, the wire 21 is pushed into the inside of the wall W before the gas cock 5 is moved along the long rod 15.

If the gas cock 5 and the gas pipe 1 are connected in this way and the gas cock 5 is attached to the wall W, the joint 4 is freely rotatable with respect to the gas cock 5, and therefore is piped inside the wall W, under the floor, or inside the ceiling. In addition, the gas pipe 1 does not have unnatural bending or twisting.

In the embodiment shown in FIG. 4, the main body 51 of the gas pipe 5 is connected to the base end 52.
On the other hand, by loosening the setscrew 53, it is possible to rotate around the X axis. According to this structure, the gas cock 5 can be more easily mounted on the wall or the like.

Another embodiment shown in FIG. 5 shows an example in which the joint 4 is not directly attached to the gas passage 7A near the gas inlet 7 but is attached via the universal joint 17. The universal joint 17 has a male screw 19 which is screwed into a female screw 18 formed in the gas passage 7A. With such a universal joint 17, the universal joint 17 can be connected to the joint 4 even with respect to an existing gas cock 5 (a female screw for connecting to a pipe is usually cut in the gas passage). .

The connection between the universal joint 17 and the joint 4 is provided with an O-ring 8 and a stop ring 9 so that the joint 4 is rotatable with respect to the gas inlet 7 and maintains a sealing property. Therefore, for example, since the universal joint 17 is also free, the set screw
When 53 is loosened, the joint 20 between the pedestal 6 and the main body 51 of the gas cock 5 cannot be freely attached, that is, even if the pedestal 6 and the gas cock 5 are integrally formed, they can be attached.

〔effect〕

As described above, according to the present invention, it has the pedestal that sandwiches the partition member in cooperation with the back plate, and the rotation mechanism is provided in the gas passage near the gas inlet formed on the mounting surface of the pedestal. A substantially L-shaped joint is attached so that it can rotate freely and keeps a seal, and this joint is connected to a gas pipe. A gas pipe connected to the inside of a wall or floor can be attached to a gas cock. At this time, the risk of unnatural bending or twisting is reduced, and safe piping can be achieved, and the connection is facilitated and workability can be improved.
