  An example of this type of meter unit that saves space is shown in FIG. Reference numeral 101 denotes a meter box which is configured such that an upper collar 101b can be attached to and detached from a lower collar 101a serving as a base. In addition, a lid 101c that can be opened and closed is provided on the upper surface of the upper collar 101b in order to confirm the pointer of the meter to be installed. The primary side of the meter box 101 is provided with a semicircular cutout in each of the lower rod 101a and the upper rod 101b, and sandwiches the inflow pipe 102a of the branch pipe 102 ((C) in the figure). On the other hand, the secondary side is provided with semicircular cutouts at two locations, and sandwiches the connection pipes 104a of the secondary side pipes 104 of the two unit unit bodies 103 (FIG. (C)). In addition, 105 is a water stop cock, 106 is a movable joint, 107 is a water meter, 108 is a fixed joint, and these constitute the unit unit body 103. It is a configuration. The stop cock 105 is connected to each branch pipe 102 b branched from the branch pipe 102, and the fixed joint 108 is connected to the connection pipe 104 a of the secondary side pipe 104.

  In this meter box, it is preferable that the upper rod 101b is shared by a unit for installing a single unit and a unit for installing a duplex unit as described above from the viewpoint of reducing manufacturing costs.

  However, when the existing upper arm is shared, there are the following problems. That is, especially when installing a plurality of unit units inside, each water meter is displaced from the center line of the meter box to the left and right (FIG. 3B). Therefore, when the lid 107a provided on the upper surface of the meter 107 is opened in order to check the pointer of the meter, the lid 107a can be sufficiently opened by interfering with the upper collar 101b depending on the inner shape of the upper collar 101b. As a result, there was a problem in checking the meter pointer (see the figure).

  In order to eliminate such obstacles, it is necessary to increase the height of the upper eyelid. Conventionally, the upper eyelid has been manufactured by molding with a synthetic resin using a predetermined mold. It was. Therefore, when another bulky upper iron is newly manufactured, it is necessary to greatly change the mold, and a great cost is required. Compared to this, if it is possible to share a conventional upper arm, this type of upper arm can be reduced in cost by molding in large quantities with synthetic resin. It is very important to make it available to all units.

  The present invention has been made in view of such a situation, and uses an existing resin upper lid as it is, and the lid and the upper lid do not interfere with each other when the lid of the meter is opened. An object is to provide a meter box. Thus, when the existing upper iron is used as it is, it is not necessary to manufacture a new mold, and the cost can be reduced.

  In order to solve the above-described problem, a meter box according to the present invention includes a lower jar that can accommodate and fix a unit unit including at least a water meter, and an upper detachable upper jar. The primary unit pipe and the secondary side pipe are provided with support portions at positions lower than the upper end edges of the opposite side walls of the lower arm by a predetermined length, and the respective unit units are attached between the pipes. The body is connectable, and the support portion is provided at a position where almost the entire unit unit body is accommodated inside the lower arm when the unit unit body is connected to the pipe.

  And the said support part employ | adopted the means that when the lid | cover of the water meter which comprises the unit unit body to accommodate is opened, the lid | cover is provided in the position which does not interfere with the said upper collar.

  The meter box has a deep lower arm and accommodates almost the entire unit unit inside the lower housing. For example, when using an existing resin upper arm, Since a wide space is formed, the unit unit or the lid of the meter and the upper lid do not interfere with each other.

  Specifically, the primary side pipe is an inflow pipe connected to the water supply main pipe, and a U-shaped notch part opened upward is provided on the primary side wall of the lower lid as a support part for the inflow pipe. The inflow pipe is fitted into the U-shaped notch and attached, and the secondary side pipe is a connection pipe connected to a separate water supply pipe, and is open to the secondary side wall of the lower arm. A means of connecting the unit unit body between the inflow pipe and the connection pipe was used by providing the cut-out section as a support section for the connection pipe and fitting the connection pipe into the U-shaped cut-out section.

  By such attachment means, the upper part of the unit unit body is hardly exposed from the upper edge of the lower eyelid, and even when the lid of the meter is opened, the lid does not interfere with the upper eyelid.

  The primary side inflow pipe is a branch pipe having a plurality of branch pipes, and unit units are connected to each branch pipe, and a number of connections corresponding to the number of the branch pipes are connected to the secondary side. A means of providing a pipe and connecting the unit units respectively was adopted.

  Similarly, in the case of a duplex unit connecting a plurality of water meters, when the lid of the meter is opened, the lid and the upper lid are prevented from interfering with each other.

  In addition, the unit unit body employ | adopted the means of comprising a water stop cock, a movable joint, a water meter, and a fixed joint in order from the primary side, for example. This is a general configuration of a unit unit.

  The meter box of the water meter according to the present invention having the above-described configuration can open the meter lid widely when the lid of the water meter is opened. Can be read.

  In addition, when an existing plastic upper arm is used, it is not necessary to make a new large upper arm, and the existing upper arm can be shared by a plurality of boxes. Therefore, it is possible to expect an economic effect that the cost and labor for manufacturing a new mold for the upper iron, the cost for molding the upper iron, and the cost for storing several kinds of upper iron can be saved.

  On the other hand, the depth of the lower arm is deeper than before, but the cost of the design change is slight, the molding effort is almost the same, compared to the case of newly manufacturing the upper arm, The increase in manufacturing cost can be reduced. Therefore, in order to achieve the intended purpose, it is only necessary to change the lower eyelid, so that the effect of reducing the entire manufacturing cost can be expected.

  Hereinafter, preferred embodiments of a meter box of a water meter according to the present invention will be described with reference to the accompanying drawings. 1 and 2, reference numeral 1 denotes a meter box which is composed of a lower rod 1a and an upper rod 1b, and the upper rod 1b is attached to and detached from the lower rod 1a as a base to which the unit unit body 2 described below is attached. It is possible. As the upper collar 1b, an existing resin upper collar used in a box of this type of meter unit is used. Moreover, the cover body 1c for confirming the needle | hook of an internal water meter is provided in the upper surface of the upper collar 1b so that opening and closing is possible. In addition, conventionally known attachment / detachment structure is adopted for attaching / detaching the upper collar 1b.

  The lower rod 1a has at least a water meter (quantity water) between a primary side pipe 3 and a secondary side pipe 4 provided via support portions 6 and 7 at a predetermined length lower than the upper edge of the opposite side wall. The unit unit 2 including the container is attached. Specifically, for example, the plurality of unit units 2 are attached via the branch pipe 5. In the embodiment shown in FIGS. 1 and 2, the branch pipe is branched into two, and two unit units 2 and 2 are attached. That is, a vertically long U-shaped notch 6 having an open top is provided as a support on the side wall on the primary side of the lower rod 1a, and the inflow pipe 5a of the branch pipe 5 is fitted into this notch. The branch pipe 5 is formed by integrally providing two branch pipes 5b with respect to one inflow pipe 5a so that the respective pipe axes are parallel to each other. This inflow pipe 5a protrudes from the lower rod 1a as the primary side pipe 3 and is connected to a water supply pipe on the main water supply side (primary side) (not shown). On the other hand, the unit unit body 2 is attached to each of the two branch pipes 5b, and the secondary side thereof is a vertically long U-shaped notch portion that opens upward as a support portion on the secondary side wall of the lower rod 1a. 7 is connected to each water supply pipe (secondary side) (not shown) that is piped door to door through protruding connection pipes 8 and 8 that are fitted in and attached to 7. This connection pipe 8 becomes the secondary side pipe 4. That is, by providing the U-shaped cutouts 6 and 7 at positions where almost the entire height of the unit unit body 2 is dropped into the lower rod 1a, the upper end portion of the lower unit 1a It is in a state of not projecting from the upper edge.

  The two unit units 2 have basically the same structure. In this embodiment, the stop cock 9 that can be connected to the branch pipe 5b, the movable joint 10, the water meter 11, and the connection pipe 8 are used. It is comprised with the fixed coupling 12 connectable to. However, the present invention is not limited to this configuration. In addition, about the water meter 11, there may be a case where adjacent meter display portions do not interfere with each other. Moreover, this structure is an example, The attachment structure is not limited to this, For example, the structure disclosed by patent document 1 mentioned above may be employ | adopted. In addition, the unit unit body 2 is appropriately fixed by a known means by forming boss portions 13, 13... On the lower collar 1 a as appropriate.

  As described above, the lower collar 1a has an upper edge that is detachable at the lower edge of the upper collar 1b, but the unit unit 2 can be attached to a position considerably lower than the upper edge of the lower collar. As compared with the prior art, the depth is made deeper, and the shape of the depth is such that almost all of the unit unit bodies 3 can be accommodated in the lower rod 1a. That is, conventionally, as shown in FIG. 3 described above, a corresponding half-moon-shaped notch is provided at the lower edge of the upper collar and the upper edge of the lower collar, and the primary inflow pipe and the secondary connection pipe are provided. Instead of what was sandwiched and attached, a U-shaped notch is provided at a position lower than the upper edge of the side wall of the lower arm by a predetermined length, and the primary inflow pipe 5a (primary pipe 3), The secondary side connecting pipe 8 (secondary side pipe 4) can be provided so as to protrude, and the unit unit body 2 can be attached at a lower position from the upper edge of the lower collar 1a. . As a result, even when the upper rod 1b having the same size as the conventional one is attached to the lower rod 1a, a wide space can be formed above the unit unit body 2, so that even when the lid 11a of the water meter 11 is opened. The lid 11a does not interfere with the upper rod 1b, so that the meter pointer can be reliably confirmed (see FIG. 2B).

  In this case, the shape of the lower eyelid 1a is deeper than before, but changing the shape of the lower eyelid is less expensive than making a new resin mold for changing the shape of the upper eyelid. The design can be changed, and an increase in cost can be suppressed to a low level. As a result, it is possible to use an existing upper arm made of resin as it is, and thus it is possible to suppress the entire manufacturing cost.

  In addition, in this embodiment, although the example which connects the unit unit body of two water meters is demonstrated, even if it is a single unit which connects one unit unit body, it is two or more Even in the case of a duplex unit that connects the unit units, substantially the same configuration can be adopted.
