Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of attaching a box stock.

As described in Japanese Utility Model Publication No. 48-28825, the conventional box-shaped box accommodates a gas-filled box inside a rectangular box, which is buried in a square hole formed in a wall or floor surface, and serves as an operating surface. The front part is exposed.

In this case, when connecting to a piping terminal led into the wall or behind the wall, first separate the box containing the gas tank and the joint that connects the gas tank and the piping terminal, and then connect the joint and the piping terminal. The connection between the joint and the gas tank must be made. Therefore, it is not possible to directly connect the box stock to the piping terminal, and the installation work is time-consuming.

Therefore, in order to directly connect the box stock to the piping terminal, for example, using the basic idea described in Japanese Utility Model Application Publication No. 51-137200, the pipe terminal is connected while the box stock is held in its entirety by a rotary tool. It is possible to screw it directly into the

However, the above-mentioned turning tool for an elbow holds the elbow with a receiving surface formed to fit the outer curved part of the bent part of the elbow, and also rotates the body of the elbow from both sides at the bent part. In a pinched state,
The screw is turned by applying rotational torque to this part, and utilizes the essential shape and strength characteristics of the elbow, which is formed in an L-shape.

Therefore, if the above-mentioned pivoting tool for the elbow, which directly holds the body of the object to be held, is used as a pivoting tool for the box-socket, gas leakage may occur in the box-socket body depending on the position where the tightening torque is applied. Since there is a risk of causing distortion, it cannot be used immediately for box-stick use.

SUMMARY OF THE INVENTION In order to simplify the work of installing a box stock, it is an object of the present invention to hold the box stock as a whole with a rotary tool so that it can be screwed into the end of a pipe while being held in this state.

The technical means of the present invention for solving the above problems is to house a gas tank in a cylindrical cover that opens on the front side, position an operating part and a plug in the open part, and connect a connection port from the center of the bottom of the cylindrical cover. is made to protrude to the back side to form a box, and on the other hand,
A through hole is drilled in the wall surface so that the end of the piping is exposed to the outside, and the entire box stock is held by a rotary tool whose tip fits into the inner surface of the cylindrical cover of the box stock, and in this holding state, the gas stock is connected. The vicinity of the mouth and the tip of the rotating tool are engaged, and the box tip is inserted into the through hole in the wall while being held by the rotating tool,
The connecting port and the piping end are screwed together by rotating the rotating tool.

According to the above technical means of the present invention, the entire box can be held simply by inserting the turning tool into the inner surface of the cover, and in this holding state, the turning tool is inserted into the through hole formed in the wall surface and the tool is inserted outside the wall. A straight screw connection is made from the end of the pipe facing the through hole.

Therefore, the conventional work of separating and reassembling each part is no longer necessary, and the work of assembling the box is simplified.

The present invention has the following unique effects.

(1) If the end of the pipe is placed in the appropriate position through the hole in the wall, the installation of the box and all subsequent related work can be done from inside the room, allowing one person to do the work.

(2) Since the rotating tool only engages with the main body of the gas cooker near the connection port, the rotating torque for fixing the connection does not act on the main body near the closure.
Accidents such as gas leaks caused by mistakes during installation work can be prevented.

(3) Since the rotary tool is used by partially inserting its distal end into the cover, it is easy to rotate the rotary tool when screwing and fixing.

(4) The box stock is held by the rotating tool by simply inserting the tip of the rotating tool into a predetermined position within the cylindrical cover of the box stock.
Therefore, there is no need for a special operation for holding, as in the case of the one described in Japanese Utility Model Application Publication No. 51-137200, and the operation is not complicated.

(5) Since the kettle body is housed inside the cylindrical cover, there is no need to worry about dirt or dust adhering to the kettle wall during work, and there is no risk of malfunction when using the kettle later.

(6) The entire box grip is held by simply inserting the tip of the rotary tool into the inner surface of the cylindrical cover, and there is no special locking mechanism like the ring spring described in Utility Model Application No. 51-137200. When removing the rotary tool from the box stock, it is only necessary to pull out the rotary tool, allowing for easy removal.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In carrying out the present invention, the tool used is a box spanner A having a shape as shown in FIG. 1, the details of which are shown in FIG. Pieces 2 and 3 are formed, and both sides of each engagement piece form inclined portions 4 and 5 that widen toward the tip. These engaging pieces 2 and 3 are connected to the tips of the legs 6 and 7, and between the legs 6 and 7 there are cutouts 8 and 9 that are open toward the lower end, and the size of this cutout is etc. are appropriately set according to the structure of the box, which will be described later.

Next, as shown in FIGS. 1 and 3, the main body 10 of the box stock is housed in a cylindrical cover 11, and a plug 12 is attached to the open side of the cover.
and the knobs 13 are located in parallel, and the cover 11
A connection port 15 serving as a gas inlet is located on the bottom 14 side of the cover and protrudes through the bottom of the cover.

Further, the bottom part 14 of the cover 11 is screwed to a flange 16 connected to the main body 10 to be integrated with the main body 10, and the flange is formed with a pair of recessed notches 17 and 18. The end surfaces on both sides of the recessed portion are appropriately sloped surfaces 19, 19. In addition, as shown in FIG. 3, the recessed notches 17 and 18 in the cover 11 are positioned at appropriate intervals across the line connecting the knob 13 and the plug 12.
There is a blank space from to the open end, and there is also a recessed part 1.
The sizes of 7 and 18 are the engagement piece 2 of the box spanner,
It is adapted to the size of 3.

Furthermore, an L-shaped gas flow path is formed in the main body 10 of the box bottle from a connection port 15 serving as a gas inlet to a plug 12, and a closure (not shown) interlocking with a knob 13 is formed inside the main body. At the same time, a safety device is attached near the plug 12, so that the closure or knob 1 can only be opened when the socket of the gas pipe connector is connected to the plug.
3, it is possible to open and close the channel.

To explain in more detail the actual mounting of the box stock in the wall 20, a piping terminal 22 is placed on the outer wall side of a through hole 21 bored in the wall 20, and a box stock with a cover 11 is connected to this as shown in Fig. 1. Temporarily tighten mouth 15, then use box spanner A
When the connecting port 15 and the piping end 22 are firmly screwed together using a screw, the box socket is fixed in the through hole.

At this time, the legs 6 and 7 of the box spanner A are inserted into the spaces 23 and 24 so that they match the notches 17 and 18 of the flange 16, and the engaging pieces 2 and 3
The box spanner may be rotated after the tip end surface of the box is brought into contact with the bottom part 14 of the cover 11, whereby one of the inclined parts 4, 5 of the engaging pieces 2, 3 and the flange 16 The inclined surfaces 19 and 19 of the recessed notches 17 and 18 engage with each other, and the main body 10, that is, the connection port 15 is screwed into the piping end 22.

In the above, since the main body 10 of the box stock is configured in a shape that is concentrated on the diameter line within the cylindrical cover 11, the recessed portions 17 and 18 are exposed on both sides of the cylindrical cover 11. Place 23,2
