Description

The present invention relates to a meter unit positioning and fixing method for setting and fixing a stopcock, a check valve, etc. at a predetermined position in a meter box, positioning and fixing this unit at a predetermined position in the meter box as a unit, and positioning and fixing the meter unit. The present invention relates to a fixing mechanism member used in a fixing method.

When installing the meter unit in the meter box, if the meter unit is not placed in the correct position in the meter box, work such as meter replacement will be hindered, and a lot of time and effort will be wasted. There was no problem.

Conventionally, in order to address such a problem, cushioning materials made of sponge rubber are attached to both ends of the base of the meter unit with an adhesive and brought into contact with the side walls of the meter box, as described in Patent Document 1, for example. By placing the meter unit in such a manner as to suppress longitudinal movement of the meter unit in the meter box, a method has been adopted in which the meter unit is positioned and fixed.

However, in the case of this method, there is a risk that the performance as a cushioning material may not be exhibited if the adhesion of the cushioning material is peeled off for some reason, not just during installation. Since the length is fixed, there is a problem that the longitudinal length of the meter box to be installed is restricted in order to demonstrate the performance of the cushioning material.

In addition, as a further countermeasure, as described in Patent Document 2, bolts are fitted into through-holes provided in the bottom plate of the meter box and the base of the meter unit on a fixed plate in which bolts are welded to a metal plate. A method of fastening by placing and tightening with a nut was also performed. In the case of this method, there is a problem that the cost is high and a tool such as a wrench is required for installation.

If the meter unit, which consists of stopcocks, check valves, etc., is not placed in the proper position inside the meter box, misalignment will occur between the end of the pipe and the meter unit, making it difficult to connect and replace the meter. Such work requires a lot of time and effort.

The present invention addresses the problem that the meter unit cannot be easily positioned and fixed in the meter box. It also addresses the longitudinal length constraint problem.

Further, conventionally, there was no clear indicator indicating the primary side and secondary side in the direction of water flow in the meter box, so there was a risk of causing a serious problem of reverse installation of meters and members.

The present invention is intended to address the above-mentioned problems, and in order to set it at a predetermined position in the meter box, a stop cock, a check valve, etc. The unit is configured as a meter unit that can be positioned and fixed at a predetermined position in the lower compartment of the meter box, and is fixed by a fixing mechanism member made of an elastic material that fits into a through hole provided in the bottom plate of the lower compartment of the meter box. It is configured to be positioned and fixed at a predetermined position in the meter box.

With this configuration, after the meter unit is temporarily placed in the meter box, the fixing mechanism member is fitted to the base frame and the lower chamber of the meter box to mount the meter unit at a predetermined position in the meter box. It is now possible to adjust the position of the meter unit inside the box, allowing it to be positioned and fixed to an appropriate position.

Furthermore, since the fixing mechanism member is mounted at or near the center of the bottom plate of the meter box, the length of the meter box in the longitudinal direction is not restricted and positioning of the mounting part is possible, and an elastic material is used. Therefore, even when the coating thickness of the base frame varies due to the coating, the dimensional difference is absorbed by the expansion and contraction of the fixing mechanism member, and the allowable range of the dimensional difference is expanded. In addition, the use of an elastic material makes it cheaper than the conventional one, and since it can be used simply by fitting it in by hand, no tools are required.

According to the present invention constructed as described above, the positioning and fixing of the meter unit in the meter box, which has conventionally required a great deal of time and labor, can be performed easily and quickly by fitting the fixing mechanism members. be.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below based on the drawings.
Reference numeral 1 denotes a lower box of a meter box, and a through hole 11 for fitting a fitting projection 51 set on the lower surface of a fixing mechanism member 5 in the longitudinal direction of the central portion is separately set on a primary side 11a and a secondary side 11b. ing. 12 is a drain hole.

Fitting projections 51 set on the lower surface of the fixing mechanism member 5 are protruding from the primary side end portion or the vicinity thereof and the secondary side end portion or the vicinity thereof of the trunk portion of the main body. The secondary projections 51b are fitted into the through holes 11b of the 11a. An arrow 54 indicating the direction of water flow is displayed on the upper surface of the body of the main body so that the direction of water flow can be confirmed. In addition, the same section may further display the nominal diameter of the water meter to be used. One or more fitting projections may be provided on the lower surface of the fixing mechanism member 5 depending on the shape of the box lower chamber.

As a method of using the fixing mechanism member 5, first, the meter unit is temporarily placed on the lower chamber 1 of the meter box. Next, the fixing mechanism member 5 is passed through the bottom long hole 42 of the base frame 4 and the fitting projection 51 set on the lower surface of the fixing mechanism member 5 is fitted into the through hole 11 of the lower chamber 1 of the meter box. Alternatively, it is also possible to fit the fixing mechanism member 5 into the lower box 1 of the meter box and fit and fix the long bottom hole 42 of the base frame 4 to the overhanging portion of the main body of the fixing mechanism member 5, and the order of use does not matter. do not have.

The fixing mechanism member 5 is made of an elastic material such as rubber. An overhang 53 is formed, which fits into the side surface of the bottom elongated hole 42 of the base frame 4, and together with the fitting projection 51 fitting into the through-hole 11 of the lower container of the meter box, the lower container of the meter box is formed. 1 and the fixing mechanism member 5, and the fixing mechanism member 5 and the base frame 4 are stably fitted. It should be noted that the main body portion of the fixing mechanism member 5 may have one or more overhangs depending on the shape of the base frame.

The base frame 4 includes an advance/retreat support member 21 having a stop cock 2 on the primary side and a meter receiving support member 31 having a built-in check valve 3 on the secondary side. to the advance/retreat support member 21, the secondary side end M2 is brought into contact with the meter receiving support member 31, the advance/retreat support member 21 is rotated to propel the end to push the water meter M, and the secondary end By pressing M2 against the meter receiving support member 31, the water meter M is sandwiched between the advance/retreat support member 21 and the meter receiving support member 31. As shown in FIG. Reference numeral 41 denotes a projection for preventing reverse mounting of the meter on the base frame 4. As shown in FIG.

When both joint ends of the water meter M are aligned with the support members 21 and 31 set on the base frame 4, the end portions of the support member 21 are propelled so that the water meter M and the support members 21 and 31 are aligned. supported by being sandwiched between
