Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a gas tank mounting structure, more specifically, to a gas tank mounting structure that can be firmly fixed to the mounting surface and is suitable for connecting metal flexible gas pipes. It is something.

[Conventional technology and its problems]

As shown in Figures 5 and 6, the general structure of a gas kettle is that a closure 2 housed inside the kettle body 1 is rotated by a knob 3, and a gas supply pipe 4 is connected to the kettle body 1. Connection pipe 5 and gas outlet pipe 6
A connecting tube 7 is provided, and the rotation of the closing member 2 allows communication and disconnection between the two connecting tubes 5 and 7.

In recent years, gas piping has been transitioning from steel pipes to metal flexible pipes, and gas pipes are also required to have a structure compatible with metal flexible pipes.

That is, when the gas pipe is a steel pipe, the pipe itself can be fixed to the structure, so there is no problem even if the gas tank itself does not have a part fixed to the structure.

On the other hand, in the case of metal flexible tubes, the ends of the tube cannot be fixed to the structure, so the gas tank must be provided with a fixing part to the structure so that opening and closing operations can be performed without any trouble.

By the way, in the gaskotok mentioned above,
When adopting a structure that is directly fixed to a structure such as a wall or floor, as shown in Figure 6, the Kotoku main body 1
Generally, a mounting seat 8 is provided on the bottom surface of the closure 2 at right angles to the axis of the closure 2.

However, in the structure in which the mounting seat 8 is provided on the bottom surface of the Kotoku main body 1 and the mounting seat 8 is fixed to the wall surface A with screws, the protrusion amount H from the seat surface of the mounting seat 8 to the tip of the knob 3 is It becomes long, and the amount of protrusion from the wall surface A is large, which is disadvantageous in terms of space.

Furthermore, when a force is applied to the knob 3 for opening/closing, etc., a large force will be applied to the fixed part of the mounting seat 8 in proportion to the amount H of protrusion from the mounting seat 8 to the knob 3, and the dimension H will be If it is long, there is a problem that the strength of the fixed part becomes weak.

[Purpose of invention]

This idea was made in order to solve the above problems, and it is possible to provide a gas tank that can be mounted on a wall advantageously in terms of space and that can improve the fixing strength of the mounting part. It is a purpose.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea provides a fixing piece with screw holes and a stepped shaft on the outside of the gas tank, and attaches it to the surface side at the end of the mounting plate, which has multiple screw holes. forming a bent part, and providing an engaging notch for the stepped shaft in this bent part, and at least one screw hole in the mounting plate aligns with a screw hole in the fixed piece when the stepped shaft is engaged in the engaging notch. The fixed piece and the stepped shaft are arranged so that the stepped shaft is hooked to the engagement notch, and with the fixed piece overlapped on the surface of the mounting plate, the gasket is tilted in the front and back direction with respect to the mounting plate. In order to achieve this, the stepped shaft protrudes further back from the back of the gas kettle than the fixed piece.

[Effect]

First, stack the mounting plate on the mounting surface of the gas tank and fix it with screws, then fit the stepped shaft of the gas tank into the engagement notch provided in the bent part of the mounting plate, overlap the fixing piece of the gas tank on the mounting plate, and then Align the screw holes with the corresponding screw holes on the mounting plate,
When screwing the screws inserted through both screw holes that communicate with each other into the mounting surface, the gas stick is fixed to the mounting surface by the screw stop and the engaging portion of the engaging notch of the stepped shaft.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 to 4 of the accompanying drawings. In addition, in the structure of the gas stick, the same parts as in FIGS. 5 and 6 are given the same reference numerals, and the description thereof will be replaced by the same reference numerals.

As shown in the figure, a pair of stepped shafts 12, 12 are provided on both sides of the upper part of the back side of the main body 1 of the gas kottoku, and a pair of stepped shafts 12, 12 are provided at the lower end of the back side so as to protrude downward. A fixing piece 13 is provided that protrudes toward the
4 is drilled.

The mounting plate 15 is formed into a substantially triangular shape, and a bent portion 16 that is bent toward the surface side is formed at the upper end portion serving as a straight edge. Engagement notches 17, 17 are provided with a width that allows the small diameter portion 12a to fit therein.

Mounting plate 15 has screw 1 on mounting surface A.
A plurality of screw holes 19 are drilled for fixing the stepped shaft 1 with the screw hole 19a located at the lower end.
2 and 12 are hooked into the hooking notches 17 and 17,
The positions are set so that the screw holes 14 of the fixing piece 13 overlap and communicate with each other.

As shown in FIG.
is hung, and with the fixing piece 13 stacked on the surface of the mounting plate 15, the Kotuku main body 1 is installed in a positional relationship with respect to the mounting plate 15 such that the axis of the closure 2 is inclined in the front-rear direction. ing. Specifically, while the stepped shafts 12, 12 protrude rearward from the back surface of the Kotoku main body 1, the fixed piece 13
From the lower part of the back side of the Kotuku main body 1 downwards,
It is bent and provided so as not to protrude toward the back side of the kettle body 1.

Note that the shape of the mounting plate 15, the number of stepped shafts 12 and engagement notches 17, the number of fixing pieces 13, etc. may be freely set according to the size of the gas tank.

The mounting structure of this invention is as described above. First, the mounting plate 15 is stacked on the gas tank mounting surface such as a wall or floor, and the screws 18 inserted into the screw holes 19 drilled in the upper part of the plate 15 are inserted. Screw it into the mounting surface A to fix the mounting plate 15 to the mounting surface A.

Next, connect the gas supply pipe 4 and the gas outlet pipe 6 to both the connecting tubes 5 and 7, and attach the main body 1 to the mounting plate 1.
5, the small diameter portion 1 of the stepped shaft 12, 12
2a into both hooking notches 17, 17, fixing piece 1
Place the seat surface of No. 3 on top of the mounting plate 15.

In this state, the screw hole 19a of the mounting plate 15 and the screw hole 14 of the fixed piece 13 overlap and match,
When screws 18a inserted into both screw holes 14 and 19a are screwed into the mounting surface, the gas stick is fixed to the mounting surface.

The fixing piece 13 is fixed to the mounting surface A along with the mounting plate 15 with the screw 18a, and the screw 18a maintains the engaged state of the stepped shaft 12 with the engagement notch 17 of the mounting plate 15, so that screwing the screw 18a is easy. A secure fixed state can be obtained.

In addition, as shown in FIG. 1, the gas tank is mounted through the mounting plate 15, so that the axis of the closure 2 is inclined at an angle of, for example, about 20 degrees to the mounting surface A. The protruding amount H of the knob 3 to the leading edge is significantly reduced, which is advantageous in terms of space, and even when installed in a corner, the knob 3 faces toward the middle of the corner, allowing smooth opening and closing operations. Become.

〔effect〕

As described above, according to this invention, a stepped shaft and a fixing piece with a screw hole are provided on the gas tank, the stepped shaft is hooked to the engagement notch of the mounting plate, and is inserted through the fixing piece and the screw hole of the mounting plate. Since the screws are screwed into the mounting surface, the gas tank can be fixed to the wall or floor via the mounting plate, and it can be firmly fixed even on rough surfaces, and it can be fixed even on rough surfaces. It can be fixed easily and is advantageous in terms of space.

Furthermore, the improved mounting strength makes it possible to put the flexible gas pipe into practical use as a gas tank.

Furthermore, after screwing the mounting plate, the gasket can be fixed with a single screw, which simplifies the mounting work and improves efficiency.
