Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a water measuring instrument housing made of synthetic resin.

(Prior Art) A conventional synthetic resin water meter housing is formed to be relatively small in many cases, mainly accommodating only a meter. Then, as a reinforcement against the earth pressure applied to the casing body, a structure is adopted in which ribs are provided on the peripheral wall of the casing body or the wall thickness of the casing body is increased.

Further, as described in Japanese Utility Model Laid-Open No. 58-171959, a reinforcing member having two reinforcing arms standing upright outward is formed on the left and right portions of a substrate, and the reinforcing member is used as a water meter. There is known a structure in which the inner surface around the opening of the casing body is supported by the upper end of the reinforcing arm by being fitted to the lower inside of the casing body.

(Problems to be solved by the invention) In recent years, in addition to the meter, a water stopcock and a check valve are also housed in the water meter housing, and the water meter housing tends to increase in size. Has become. Therefore, in order to increase the strength of the housing body against earth pressure, reinforcing ribs are provided on the inner and outer surfaces of the housing body, or the wall thickness of the housing body is increased to reinforce the housing body. It becomes difficult to prevent the inward bending of the both side walls in the longitudinal direction due to the earth pressure because it becomes longer in the direction along the direction, and therefore the lid fitted to the upper end opening of the casing body is pushed from both sides. There was a problem that it interfered with opening and closing.

Further, in the structure disclosed in Japanese Utility Model Laid-Open No. 58-171959, since the substrate of the reinforcing member is fitted to the lower inside of the casing body, the reinforcing member interferes with the installation of the meter, It is not possible to store a water pipe connected to a water stopcock, a check valve, etc. by covering the casing main body after covering it with the casing main body, the workability is poor, and the lid cannot be supported. I have a problem.

The present invention has been made in view of the above problems, and prevents deformation of the water meter housing main body in the longitudinal direction to prevent deformation due to earth pressure, facilitates opening and closing of the lid, and lowers the lid. It is possible to prevent the bending of the meter and to provide a water meter housing that does not hinder the meter reading or replacement of the meter.

(Means for Solving Problems) A water meter housing of the present invention is a synthetic resin water meter housing main body having a lid fitting portion formed on an upper surface opening portion, and an opening / closing opening on the upper surface opening portion of the housing main body. A reinforcing body which comprises a synthetic resin lid body which is freely fitted and supported, and which is provided in the width direction in the casing body near the lower position of the lid body fitting portion of the casing body and supports the lid body. Is provided so as to be slidable and removable in the longitudinal direction of the casing body.

(Operation) The water meter housing of the present invention prevents the housing body from being deformed inward by earth pressure by arranging the reinforcing body in the width direction of the central portion in the length direction of the housing body, and also the lid. It is also possible to prevent the body from bending downward, and by sliding the reinforcing body from the center to move it, it does not interfere with the meter reading, and the reinforcing body can be used when replacing items such as meters. Ejecting from the case body does not interfere with the loading and unloading of stored items.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a synthetic resin casing body, which has a rectangular cross section and is formed into a hollow cylindrical shape in which a downward expansion is performed, an opening portion is provided at an upper portion, and a lower surface is opened.

The casing main body 1 has an upper end edge bent inward, further bent downward, and bent inward to form an annular lid fitting portion 3 surrounding the opening 2.

Further, horizontal guide rails 5 and 5 are provided on the inner surfaces of the side plates 4 and 4 on the long side of the casing body 1 so as to face the positions below the lid fitting portion 3. Reinforcing rib pieces 13 are provided downward from the lower portions of the guide rails 5 and 5, and the reinforcing body 6 is slid on the guide rails 5 and 5 by inscribing both end faces of the both side face plates 4 and 4. It is supported freely and detachably.

Further, water pipe inlets 8 are opened at the lower ends of both side plates 7 on the short side of the casing body 1.

In addition, both side plates 4 and 4 and both side plates 7 of the casing body 1,
A large number of ribs 9 are vertically provided on the inner and outer peripheral surfaces of 7.

Next, in the figure, 10 is a lid made of synthetic resin, and ribs 11 are vertically and horizontally projected on the lower surface. The lid 10 has a peripheral edge 12
Is supported by the lid fitting portion 3 of the casing body 1, and the center of the lower surface of the rib 11 is supported by the reinforcing body 6.

The operation of the above-described embodiment will be described below.

When the opening 2 of the casing body 1 is closed by the lid body 10, the reinforcing body 6 is supported by the guide rails 5 and 5 at both ends at the central portion in the length direction of the casing body 1, and at both end surfaces of the reinforcing body 6. It supports both side plates 4 and 4 near the opening 2 of the casing body 1 against earth pressure to prevent deformation, and also supports the center of the lower surface of the rib 11 of the lid 10 to prevent downward deformation. There is.

Next, when the pointer is opened and the lid 10 is opened, the reinforcing member 6
May interfere with the reading of the meter, but reinforcement 6
Move them in parallel on the guide rails 5 and 5 so that they do not get in the way.

Further, at the time of replacement of a storage item such as a meter, the reinforcing body 6 is removed from the guide rails 5 and 5 so as not to disturb the replacement work.

Further, FIG. 5 shows another embodiment of the reinforcing body, and the reinforcing body 6
Is composed of a pair of reinforcing pieces 6a, 6b, and the mutually opposite screw rods 14a, 14b protruding in the longitudinal direction of the reinforcing pieces 6a, 6b are attached to the female screw cylinder 1
It is integrally connected by being screwed to both ends of 5.

In the reinforcing body 6 of the embodiment shown in FIG. 5, both sides of the casing main body 1 are adjusted by rotating the female screw cylinder 15 to change the interval between the opposing screw rods 14a and 14b and adjusting the length of the reinforcing body 6. It can be adapted to different widths between the face plates 4 and 4, and is also convenient for attaching and detaching from the guide rails 5 and 5.

(Effect of the Invention) According to the present invention, the substantially central portion in the width direction near the opening of the housing body is supported by the reinforcing body to prevent deformation of the housing body due to earth pressure, and the opening of the housing body. The lower surface of the lid that is fitted to the part is supported by the reinforcing body to prevent downward bending, and there is no bulging inward of the opening of the housing body, which hinders opening and closing of the lid. Never. Furthermore, since the reinforcing body can be slidably attached and detached freely, it does not interfere with reading the meter during meter reading, and when replacing the meter etc., the reinforcing body can be removed from the housing body to prevent the meter from moving in and out. Never be.
