Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an LP gas supply device used to supply LP gas from a cylinder to a point of use.

(Prior Art) Conventionally, when supplying LP gas from a cylinder to a place of use in a home or a store, as shown in FIG. 4, for example, an automatic switching regulator a, an intermediate cock b, a gas meter c are used. A gas supply device such as a pipe is connected by a predetermined pipe e through a pipe element such as a bend d, and a proper pipe work is performed up to the use place while directly supporting the appropriate places on the outer wall of the building or the like with a support fitting f or the like. Then, the inlet side connecting fitting g of the automatic switching regulator a and the outlet side connecting fitting i of the cylinder h are connected by a high pressure hose j for use. Also, for example, the actual Kaihei 1-
As disclosed in Japanese Patent No. 91199, there is also a unit in which the above-mentioned gas supply device is connected to the surface of a mounting plate by piping and supported to form a unit.

(Problems to be solved by the invention) With the former piping method, there is a lot of piping work on site, and large tools such as a thread cutting machine and pipe wrench are required. Becomes larger,
Further, not only a plurality of workers are required, but it is difficult to make the work quality uniform.

Also, with the latter piping method using the device, it is possible to reduce the piping work in the field by unitizing,
As mentioned above, gas supply devices such as automatic switching regulators, intermediate cocks, and gas meters are simply connected by pipes to the surface of the mounting plate to support them. It is easily exposed and has problems in terms of corrosion and durability, and is also vulnerable to protection against falling objects and mischief.

The present invention aims to solve the above problems.

(Means for Solving the Problems) In order to solve the above problems, the apparatus for supplying LP gas of the present invention has standing plate portions 3a, 3b on both side edges of a main body supporting plate 1 provided with mounting brackets 2a, 2b. And the inlet side connection fittings 4a, 4b are fixed to the standing plate portions 3a, 3b, and the main body support plate 1 is provided with a gas supply device such as an automatic switching regulator 7, an intermediate cock 8 and a gas meter 10, and an outlet. The side connection fitting 11 is fixed, and these constituent elements are connected by a predetermined piping element, and a communication hole 15 is formed at a portion of the main body support plate 1 corresponding to the piping connection side of the outlet side connection fitting 11. The device body A and the standing plate 3
