Abstract

PURPOSE:To absorb mounting errors in a height and direction due to the errors of working by a method wherein a gas pipe is connected to the lower surface of a bracket and the cock is connected to the upper surface thereof while the bracket is formed previously with the transparent hole of up-and-down direction to communicate a gas hole with the inside of the cock through the transparent hole. CONSTITUTION:The gas pipe 4 is connected to a bent section 2b at the upper end of the bracket 2 and the cock 6 is connected to the upper surface of the bent while the bent section 2b is provided previously with the transparent hole 12 of up-and-down direction to communicate the gas hole 5 with the inside of the cock 6 through the transparent hole 12. The transparent hole 12 is worked by means of cold forging or the like so as to be formed with a tapered ring 13 on the lower surface thereof and an annular boss 14 on the upper surface thereof integrally, the gas pipe 4 is fitted into the ring 13 at the gas hole 5 and is connected to it by means of projection welding or the like while the cock 6 is fitted into the annular boss 14 at the recess of the lower surface of the cock 6 and the location thereof is determined. Accordingly, a big error in the mounting height and direction of the cock will never be generated.

Description

[Detailed description of the invention] Regarding attached equipment.

Conventionally, this pushing device has been used to connect a gas pipe C and a gas hole on the top surface of the gas pipe C into the combustion appliance main body a through a mounting platen b extending upward from the bottom surface of the combustion appliance main body a, as shown in the first figure. A type is known that has a gas cock θ on the upper side that communicates with the gas pipe c), but in this case, the gas pipe c) is connected in advance to the gas hole d, as shown in Japanese Publication No. 5J-20740. A connecting pipe (F) which is fitted into and projection welded to the gas pipe (C) is provided with a flange (G) at the upper end of the connecting pipe (F), and the cock (F) is located at the flange (G) at the upper end of the connection pipe (F), as shown in the figure. ) and fixed thereon by spot welding or other methods, in which the gas cock θ is placed on the bracket b via the gas pipe C and the connecting pipe f. Due to the fact that it is installed above it, the installation height tends to increase as a whole, and there are also some errors in the height and direction due to machining errors in the 1 part of the connecting pipe and other parts. accompanied by inconvenience.

The object of the present invention is to obtain a device free from such inconveniences, in which a gas pipe is connected to the upper surface of the gas pipe through a mounting plate extending upwardly from the bottom of the combustion appliance body. 1 degree earth 11j1 noj su T connected to the gas hole of
Place the metal fittings in place, and connect the lower part of the scrap pipe metal and the entire cock to the surface, and attach the vertical transparent to the bracket in advance. The gas hole 'fr: communicates with the inside of the cock through the through hole.

An example of the implementation of the present invention will be described in a separate sheet attached to the same song.

Figures 21'N to 4 are examples of this, and (1)
t, 1, the combustion appliance main body, (2) the bottom force and the bracket (for the bracket)
2) is the bent part of the lower girl 1'IJ (at 2aJ, it overlaps with the bottom plate (1a) of the combustion appliance) and screws (3)
At the bent part (2b) of the upper end, the gas hook is connected to the gas hole (5) on the upper surface of the gas pipe (4). (6) Be fully prepared. The gas nozzle (7) extending forward opens into the mixing pipe (8) of the burner in front of the core. n of (1): blank hole t1 formed in the i-side panel (1b). It is assumed that the ol inner metal is inserted through l and is provided with an operating knob 0υ. The gas u (4) (r, f, required V) extends longitudinally in the lateral direction, and is provided with a plurality of gas holes (5) at appropriate intervals, and the upper side of each gas hole (5). Each gas cock (6) was fully equipped, so that several burner stations could be equipped.

Although the above does not particularly fit with conventional methods, according to the present invention,
The gas pipe (4) is tied to the lower part of the bent part (2b) at the upper end of the bracket (2) and the entire upper part of the cock (6), and is attached to the bent part (2b) in advance. ”The gas hole (5) is connected to the through hole α2 with all the two downward through holes u3.
A communicating type M was installed in the cock (61) through a gold plate.

To explain this in detail with reference to the illustrated one, the through hole a2+ is machined by cold forging or other means as shown at 1111 in FIGS. 5 and 4, and a tapered ring ([3
) and a moat-shaped boss (141) are pre-formed integrally on the upper part, and a class ring (1; The projection 7' is connected to the projection 7', and the cock (6) is attached to the four parts of the lower surface. Then, that evening, at 1.+11.11, I made it possible to fix the rails with other parts.

In this way, according to the present invention, the lower surface of the bracket for attaching all the gas pipes and the entire gas cock are connected, and the gas cock is connected to the gas 11 and all the connecting pipes extending from it, and the upper side thereof ni+! It does not have the above-mentioned inconveniences of the conventional cocks, and in other words, the cock does not have any large errors in its installation height and installation method.
This is especially advantageous in a type in which a plurality of gas cocks are all arranged in one common gas pipe, and furthermore, the gas hole of the gas bait and the gas cock are connected to a vertical through-hole formed in advance in the bracket. They communicate with each other through the two, and have the effect of providing good and reliable communication between the two.
