Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Industrial field of application) The present invention relates to a height adjusting device for a water meter casing, and in particular, is inserted between a lower casing and an upper casing. Related to a control piece.

(Prior Art) The depth of the water pipe buried in the ground and the water meter installed in the water pipe from the surface depends on the installation conditions. On the other hand, since the upper surface of the water meter housing that houses the water meter must be exposed so as to match the ground surface, the height of the water meter housing must be adjusted according to the depth. I have to.

Therefore, conventionally, when a water meter housing is installed, a bottom plate as a lower housing that configures the water meter housing and a disposition on the bottom plate are provided according to the depths of the water pipe and the water meter from the ground surface. The height is adjusted by inserting an adjustment frame between the main body of the water measuring device as the upper casing. As an adjustment frame of this type, for example, one including a pair of adjustment pieces as described in Japanese Utility Model Publication No. 60-16674 is proposed or used.

However, since the conventional adjustment frame has a fixed and relatively large height, it is difficult to perform fine adjustment of a height of, for example, about 1 cm. In this way, since there was no dedicated member such as an adjustment frame for fine adjustment of height, conventionally, wood chips or pebbles were sandwiched between the bottom plate and the water meter housing body directly or together with the adjustment frame. I sometimes made fine adjustments to the height. However, when wood chips or pebbles are used as described above, a gap is likely to be formed between the bottom plate and the main body of the water measuring device. In addition, there was a situation in which the meter could not be read unless soil and sand were removed.

Even when the adjustment frame is used, fine adjustment of the height can be performed if the adjustment frame has a low height. However, if the height of one adjustment frame is constant, adjustment frames of various heights must be prepared in advance in order to perform significant height adjustment efficiently, which is expensive in terms of price. Become. On the other hand, when performing a large height adjustment, it is conceivable to stack only low adjustment frames in multiple stages, but this makes the adjustment work complicated and increases the number of necessary adjustment frames, resulting in an increase in cost.

(Problems to be Solved by the Invention) As described above, the conventional height adjusting device for a water meter casing has an adjusting frame having a relatively large height inserted between the lower casing and the upper casing. Therefore, there was a problem that the height could not be finely adjusted. In addition, if the adjustment frame is lowered or a low adjustment frame is prepared in addition to the high adjustment frame to enable fine adjustment, the adjustment work becomes expensive and troublesome. .

The present invention is intended to solve such a problem, and it is possible to easily perform fine adjustment of the height of the water meter casing and also to perform large adjustment of the height easily. Moreover, it is an object of the present invention to provide a height adjusting device for a water meter casing that can be manufactured at low cost.

[Constitution of device]

(Means for Solving the Problem) The present invention adjusts the height of a water meter housing including a lower housing having an upper surface opened and an upper housing having a lower surface connected to the lower housing. A height adjusting device for a water meter casing, which comprises an adjusting piece inserted between a peripheral portion of an upper surface opening of the lower housing and a peripheral portion of a lower surface opening of the upper housing. In order to achieve the above-mentioned object, the adjusting piece is integrally formed of a flexible material, and the adjusting piece has a vertical groove extending vertically and a horizontal groove extending horizontally. The slits are formed in a lattice shape, and the adjustment pieces are divided into blocks that are integrally connected by a thin portion and are arranged in a plurality of rows in the vertical direction and the horizontal direction.

(Operation) In the height adjusting device for a water meter casing of the present invention, when installing the water meter casing, when adjusting the height of the water meter casing, if necessary, depending on the height to be increased, , The blocks are integrally connected in appropriate ones of the horizontal slits of the concave groove shape of the adjustment piece which is divided into blocks arranged in a plurality of rows in the vertical direction and the horizontal direction by the grid-like slits. By cutting the thin part,
The height of the adjusting piece is made approximately equal to the increasing height.
Along with this, depending on the length of the peripheral portion of the opening on the upper surface or the lower surface of both housings, if necessary, cut the thin-walled part in an appropriate vertical groove-shaped vertical slit of the adjustment piece. By doing so, the length of the adjusting piece is also adjusted. Then, by appropriately bending the thin portion in the vertical slit extending in the vertical direction of the flexible adjusting piece, the adjusting piece is bent in the horizontal direction in accordance with the shapes of the peripheral portions of the openings of the both housings, This adjustment piece is inserted between the peripheral portion of the upper surface opening of the lower casing and the peripheral portion of the lower surface opening of the upper casing.

(Embodiment) Hereinafter, a configuration of an embodiment of a height adjusting device for a water meter casing of the present invention will be described with reference to the drawings.

 First, the configuration of the water meter casing 10 will be described with reference to FIG.

Reference numeral 11 denotes a bottom plate serving as a lower housing having an open upper surface. The bottom plate 11 is formed in a dish shape, and has a flange 12 protruding outward in the horizontal direction at a peripheral portion of the upper surface opening. Also,
13 is the main body of the water meter housing as an upper housing with an open lower surface,
The water meter housing main body 13 is formed in a frame shape and is joined to the bottom plate 11, and has a flange 14 protruding outward in the horizontal direction at the peripheral portion of the lower surface opening. . The flange 14 has substantially the same shape as the flange 12 of the bottom plate 11 and is joined thereto. Further, although not shown, the flange 12 of the bottom plate 11 is provided with a plurality of engaging projections protruding upward. On the other hand, the flange 14 of the water meter housing body 13 is formed with a plurality of engagement holes into which the engagement protrusions are respectively engaged.

Further, water pipe passages 17 are formed on both end surfaces of the water meter housing 10 so as to extend over the joint between the bottom plate 11 and the water meter housing body 13. Further, although not shown, the water meter housing main body 13 has an upper surface opened, and the upper surface opening is closed by a lid so as to be openable and closable.

Next, the bottom plate 11 and the flange of the water meter housing main body 13
The structure of the adjusting piece 21 that is inserted between 12 and 14 and adjusts the height of the water meter housing 10 will be described with reference to FIGS. 1 to 3.

The adjusting piece 21 is integrally formed of a flexible material such as polypropylene, polyethylene, hard rubber or elastomer in a horizontally elongated flat plate shape. The horizontal width of the adjusting piece 21 substantially matches the width of the lower flanges 12 and 14 of the water meter housing 10. In addition, the length of the adjustment piece 21 in the horizontal longitudinal direction is such that the flange 1 in the half on one side of the water meter housing 10 is
It is almost equal to the length of 2,14. It should be noted that one side of the water measuring device casing 10 referred to here is based on a vertical plane connecting both water pipe openings 17.

The adjusting piece 21 has a plurality of vertical slits 22 in the form of deep grooves extending in the vertical direction and the adjusting piece 21 in the horizontal direction.
And a plurality of deep concave groove-shaped lateral slits 23 extending in the longitudinal direction are formed in a lattice shape. Due to these slits 22 and 23, the adjustment piece 21 has a thin wall portion 24 located on one side surface thereof.
Are divided into blocks 25 that are integrally connected by and are arranged in a plurality of rows in the vertical direction and the horizontal direction. In addition,
The horizontal slits 23 are formed at equal intervals, but the vertical slits 22 are formed closer to the corners of the water meter casing 10 than to other parts. The height of one block 25 is, for example, about 1 cm. The vertical slit 2
A through hole 26 is formed at the intersection of 2 and the lateral slit 23. These through holes 26 are for absorbing the generation of wrinkles when the thin portion 24 is compressed.

Further, in each of the blocks 25, a concave portion 27 is formed in the lower surface portion and the upper surface portion of the adjusting piece 21 so that the engaging protrusion of the flange 12 of the bottom plate 11 of the water meter casing 10 is engaged.

Particularly, the adjusting piece 21 of the illustrated embodiment has a symmetrical shape in the vertical direction and the longitudinal direction. In FIGS. 1 and 2, only the longitudinal half of the adjusting piece 21 is shown.

 Next, the operation of the above embodiment will be described.

When installing the water meter housing 10 in the ground, the water meter housing main body 13 is joined on the bottom plate 11, and the water pipes are inserted into both water pipe openings 17 formed by this, and the water pipe The water meter provided in the pipe is housed in the water meter housing 10. At this time, the height of the water meter housing 10 must be adjusted so that the upper surface of the water meter housing main body 13 matches the ground surface.
In reality, the height of the water measuring device casing 10 will be appropriately increased.

If it is not necessary to increase the height of the water meter housing 10, the flange 14 of the water meter housing body 13 may be directly joined to the flange 12 of the bottom plate 11.

On the other hand, if it is necessary to increase the height of the water meter housing 10, depending on the height to be increased, the horizontally extending horizontal slit 23 that divides the adjustment piece 21 into blocks 25 arranged in the vertical direction is provided. In a suitable one of them, the thin portion 24 which is continuous with the block 25 is cut with a cutter knife or the like. As a result, the height of the adjusting piece 21 is made substantially equal to the increasing height. For example, if the height to be increased for adjustment is 2 cm, cutting the second thin part 24 from the top or the second from the bottom will make the adjustment piece 2 with a height of about 2 cm.
I can do one. In any case, since the thin-walled portion 24 is cut, the cutting can be easily performed. Also, the height to increase is about
If it is about 5 cm, the uncut cutting piece 21 may be used as it is.

Then, in each vertical slit 22 that extends in the up-down direction that divides the adjustment piece 21 into blocks 25 arranged in the horizontal direction,
By appropriately bending the thin portion 24, in accordance with the planar shape of the flanges 12 and 14 in one half of the water meter casing 10,
For example, the adjustment piece 21 is bent in the horizontal direction so that the thin portion 24 side becomes the inner peripheral side. At this time, the thin portion 24 of the flexible adjusting piece 21 can be easily bent. The vertical slits 22 are opened when the thin portion 24 side is the inner peripheral side. In this way, a pair of adjusting pieces 21 that match the planar shapes of the flanges 12 and 14 on both sides of the water meter casing 10 are produced. Since the water meter casing 10 itself has a symmetrical shape with respect to the water pipe passage opening 17, both adjusting pieces 21 have exactly the same shape.

At the same time, as shown in FIG. 4, both adjusting pieces 21 are placed on the flanges 12 on both sides of the bottom plate 11 with the recesses 27 on the lower side. In this state, the plurality of engaging projections of the flange 12 are engaged with the recesses 27, respectively, so that the shape of the adjusting piece 21 is maintained and the positional displacement of these adjusting pieces 21 is prevented. Become. Further, the flange 14 of the water meter housing body 13 is placed on the adjustment pieces 21.

Since the original adjusting piece 21 has a vertically symmetrical shape including the concave portion 27, it can be used even if it is turned upside down. Therefore, from the original adjusting piece 21 having the exact same structure to the water meter. A pair of adjusting pieces 21 to be inserted into both sides of the casing 10 can be made together.

As described above, according to the above configuration, by cutting the adjusting piece 21 at an appropriate position, it is possible to easily cope with the difference in height of the water meter casing 10 to be adjusted. And the adjustment piece
By appropriately reducing the distance between the lateral slits 23 in the 21, it is possible to easily perform fine adjustment of the height in units of 1 cm, for example. At the same time, the height of the water meter housing 10 can be easily adjusted significantly. Moreover, this is possible at low cost. That is, since it is not necessary to manufacture adjusting pieces of various heights at the molding stage, the cost can be reduced, and it is not necessary to stack the lower adjusting pieces in multiple stages when the height is largely adjusted. Therefore, the adjustment work is not complicated, and by not requiring a large number of adjustment pieces,
Can be cheap.

The vertical slits 22 may be formed densely and at substantially equal intervals, particularly at both ends in the longitudinal direction of the adjusting piece 21.

Then, by appropriately increasing the number of the vertical slits 22, it becomes possible to easily cope with the difference in the planar shape of the water meter casing 10. That is, in accordance with the circumferential length of the flanges 12 and 14 of the water meter casing 10, the thin portion 24 is cut in an appropriate one of the vertical slits 23 extending in the vertical direction of the adjustment piece 21, and the longitudinal end of the adjustment piece 21 is cut. Cut off the part and adjust piece 21
By adjusting the length of the water meter housing 10, it is possible to cope with the difference in the planar shape of the water meter housing 10.
