DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a gas meter in a so-called pipe shaft space for collecting and piping gas pipes, water pipes, cooling / heating pipes, hot water supply pipes and the like in an apartment house.

[0002]

2. Description of the Related Art In a multi-family housing, a gas meter is mounted in a narrow pipe shaft space. For this reason,
There are many restrictions on the position and orientation of the mounting, and accordingly, various devices have been devised for the mounting device.

For example, in the case of the invention according to Japanese Patent Application No. 7-172017, the screw holes 24 are formed in the mounting substrate 20 in multiple angles.
Is provided so that the mounting direction of the rotary header 50 is adjusted so that the gas meter and the gas pipe can be easily fixed in a narrow place. In addition, Japanese Patent Application No. 8
In the case of the invention according to No. -111753, by attaching the upward mounting plates 7 and 15 to the entry side member 3 and the exit side member 9 and fixing them to the support fitting 1, it is possible to adjust the position in the left and right direction. I have.

[0004]

However, the above-mentioned Japanese Patent Application No.
In the invention of -172017, the mounting direction can be adjusted, but the right and left distance cannot be adjusted. Therefore, if there is an error between the distance between the base and the meter, it is impossible to connect each connection part. There is a problem that power is applied.

On the other hand, in the invention according to Japanese Patent Application No. 8-111553, it is possible to adjust the distance between the bases of the meter. However, when adjusting the mounting direction, the meter is temporarily tightened with a predetermined torque. Since it is necessary to further tighten and loosen things for direction adjustment,
Excessive force is applied to each part, and a problem occurs in the sealing performance. However, when installing the gas meter, it is often necessary to adjust the position, the left-right spacing, and the direction. In particular, in a narrow pipe shaft space, due to the positional relationship with other pipes and the gas water heater installed in the pipe shaft space, adjustment of the interval according to the base of the gas meter and position adjustment of the gas meter. In addition, fine adjustment of the connection direction with the access pipe is indispensable.

SUMMARY OF THE INVENTION It is an object of the present invention to mount a gas meter in a pipe shaft space so that the position of the gas meter, the distance between the gas meter and a fine adjustment in the direction of the gas pipe can be easily adjusted. The idea is to propose a device.

[0007]

In addition, it can be adjusted according to the width (length) of the space. The fixing part is fixed to the side wall of the pipe shaft space using screws or fixing bolts.

A fixed plate facing backward or upward, or both, is integrally formed on the inlet and outlet elbows. The rhombic plate is formed in such a size that the width at the center is hooked to the inner edge of the fixing groove with respect to the fixing groove of the support bracket main body. However, the outline of the rhombic plate is a rhombus, and each corner may be formed in an arc shape.

The gas plug has a function as a so-called main plug and a function as a mounting pipe for a gas meter. The distributor functions as a gas meter mounting pipe in the same manner as the gas stopper, and also in the direction of the gas pipe (gas outlet direction).
Is formed so as to be able to be taken out in the left-right direction or upward direction. In addition, a purge port (test port) is formed in this distributor.

The effects of the present invention are as follows. 1. A fixed plate is integrally formed on the inlet elbow and the outlet elbow, and the elbow can be fixed in the fixing groove of the support bracket main body using this fixed plate and a rhombic plate.
As shown in FIG. 7, the rhombic plate can be rotated in the support bracket main body, so that the direction of the inlet and outlet elbows can be freely adjusted. Therefore, when it is necessary to adjust the direction of the elbow, no excessive force is applied to each connecting portion. Also, because of the rhombus shape, the area to be engaged with the inner edge of the fixing groove of the support bracket main body is increased.
Engagement is assured.

2. Backing plate (plate) in the support bracket body
Is made into a diamond shape, so that the inlet elbow and gas stopper and the outlet elbow, the distributor and the gas meter are connected first, and the temporarily fixed rhombic plate is installed obliquely into the fixing groove, and then permanently fixed. This makes it possible to easily mount the gas meter.

3. By providing the rhombic plates on the inlet side and the outlet side, respectively, the direction of the elbow can be adjusted independently and the gas meter can be fixed according to the distance between the inlet and outlet ports, so that no excessive force is applied to each connection part .

4. Since the fixing plates of the inlet and outlet elbows are formed to face rearward and upward, the position of the gas meter can be adjusted according to the space in the pipe shaft space.

5. By forming the rearward and upward fixing plates for the inlet and outlet elbows, one elbow can handle two types of mounting directions. Therefore, the cost can be reduced by reducing the number of parts.
