Description

  In the meter box, the joint mechanism for connecting the primary side and secondary side pipes to the ends of the meter unit is fixed to both sides of the meter box by an elastic earth retaining member such as rubber. It is related with the meter unit for water supply with a holding | maintenance function comprised by hold | maintaining a meter unit fixedly.

  Conventionally, the meter box for storing and housing the meter unit is either a single type or a double type, and the bottom of the meter box in order to install the meter unit 11A such as a water meter, a stopcock, and a joint in the meter box 1. After fixing the meter unit 11A by setting a fixed base 12 for fixing a water meter, a stop cock, a joint, etc. to the tub 1b, foreign matter such as earth and sand from the outside of the pipe through holes 13a, 13b on both sides of the meter box An earth retaining plate 160 for preventing mixing is installed to close the pipe through holes 13a and 13b (Non-patent Document 1).

  In addition, as described in Non-Patent Document 1, the retaining plate 160 is formed of a thin material such as a plastic thin plate, and the meter unit can be installed only with a function of preventing foreign matter contamination such as earth and sand by closing the pipe through hole. It does not have a fixed holding function.

  Conventionally, when a meter unit is installed, a retaining plate 160 as shown in FIGS. 5 and 6 is used as this type of retaining member, and a radial notch 162 is formed around the center of a plate material such as plastic. This requires a troublesome work of fixing with an earth and sand while pressing the pipe through-hole portions 13a and 13b from the outside of the pipe through-hole portions 13a and 13b. There was a problem.

  Furthermore, depending on the setting environment, there is a problem that foreign matter such as earth and sand may be mixed in the meter box, which may cause trouble in replacement of the water meter.

  In addition, since the base or the like is fixed to the lower arm with a bolt or the like for holding the meter unit, a lot of time and labor are required for processing and assembling the base.

  The invention of the present application addresses the above problems and provides a meter unit that can fix the retaining plate function and the joint of the meter unit in the box, thereby reducing the number of parts and the number of processing and assembly steps. The purpose is to provide a water meter meter with a holding function that is inexpensive and has high production efficiency.

  The present invention is intended to address the above-described problem, and has a predetermined shape in which an outer shape is fitted to the through-hole portion on both sides of the meter box and the inner shape holds the outer shape of the joint portion of the meter unit. A thick elastic earth retaining member was fitted to position and stabilize the meter unit in the meter box.

  This configuration prevents positioning of the meter unit in the meter box and rattling during transportation, prevents contamination from foreign matter such as earth and sand from the outside at the time of installation. Impacts such as ground subsidence can be absorbed by the earth retaining member to enhance protection of the meter unit and the piping member.

  The meter box that accommodates the meter unit is divided into an upper cage and a lower cage (if necessary, an intermediate cage or the like that adjusts the height is inserted between them). The primary and secondary pipe through-holes are formed on both sides of each ridge by fitting the heel on either side, or on either one of the upper and lower ridges. It has come to be.

  As for the earth retaining member, the inner shape portion that holds the joint portion of the meter unit to be accommodated is sandwiched by vertically dividing the member into two parts as means for fitting the joint portion, or by a notch that leaves one end. The joint portion of the meter unit is configured to be held by the inner shape portion so as to open and close the inner shape portion.

  The outer shape of the earth retaining member is configured to fit into the concave and convex shape formed on the inner shape of the pipe through hole formed on both sides of the meter box, and is strengthened on the end surface as necessary Provide a flange.

  The present invention is configured as described above to prevent positioning of the meter unit in the meter box and rattling during transportation, and to prevent contamination of foreign matters such as earth and sand from outside during installation. Furthermore, after installation, impacts such as earthquakes and ground subsidence can be absorbed by the earth retaining member, thereby enhancing protection of the meter unit and the piping member.
