Next, the front door 2 that is a main part of the present invention will be described.
The front door 2 is formed in an L-shape comprising a covering portion 2a that covers the front surface of the case body 3 and a bent portion 2b that is integrally bent backward from the covering portion 2a and covers the right side surface of the case body 3. It is a thin plate member and is formed slightly longer in the vertical direction than the length of the case body 3 in the vertical direction. A hinge plate 32 having a hinge hole 31 as will be described later is integrally projected on the rear end upper portion of the bent portion 2b of the front door 2, while the rear end lower portion of the bent portion 2b of the front door 2 is A hinge plate 34 having a circular shaft hole 33 is integrally projected.

  A long hole 35 that is long in the vertical direction is formed in the lower left end of the covering portion 2a of the front door 2, and the front door 2 is locked in a closed state on the rear side of the long hole 35. A locking mechanism 36 is provided. The lock mechanism 36 is provided with a latch piece 37 that latches on a lock pin 43 provided on the case body 3 side, and grips the lower left end portion of the front door 2 by inserting a finger or the like through the long hole 35. As a result, the lock mechanism 36 is pushed rearward and rotates together with the latching piece 37. Furthermore, a rubber cushioning member (covering member) 38 is bonded to the rear surface of the covering portion 2a of the front door 2 over substantially the entire surface. The lock mechanism 36 has a biasing means built in, and is always biased to the normal position when not pressed.

  In the front door 2 as described above, the shaft 41 protruding from the rear end of the right upper edge of the case body 3 is inserted into the hinge hole 31 of the hinge plate 32 and the hinge pin 40 is inserted into the shaft hole of the hinge plate 34. 33 and the small hole 42 formed in the rear end of the lower right side of the lower surface of the case main body 3 are inserted from below into the case main body 3 so that the case main body 3 can be opened in a single-sided manner. And the front door 2 is in the state which covered the front surface of the case main body 3, at least the window part 8 in the closed state, and the watt-hour meter etc. cannot be visually recognized from outside unless the front door 2 is opened. Yes. In the closed state of the front door 2, the buffer member 38 is in close contact with the front surface of the case body 3, so that rainwater or the like does not enter between the front door 2 and the case body 3. In the front door 2, the hinge plates 32 and 34 are provided inward from the upper end and the lower end of the bent portion 2 b, and the upper and lower hinges are in contact with the upper and lower surfaces of the case body 3. The portion is made difficult to see from the front and the like, and the aesthetics of the watt-hour storage case 1 are improved.

Here, the structure of the hinge portion between the front door 2 and the case body 3 (substrate 5) as described above, that is, the shaft 41 and the hinge hole 31 of the hinge plate 32 will be described with reference to FIGS. FIG. 7 is a partial explanatory view showing the shaft 41 and the hinge plate 32 in an enlarged manner, and FIG. 8 shows the hinge portion in an opened state (a) and a closed state (b) of the front door 2 in an enlarged manner. It is a partial explanatory view.
The shaft 41 is a columnar body that is cut out so as to have a semicircular cross section, and is erected with the flat surface that is the cutout surface facing outward. On the other hand, the hinge hole 31 has a fan shape having substantially the same diameter as that of the shaft 41 and a central angle of a predetermined obtuse angle (for example, 240 degrees), that is, a shape in which a projecting piece (projection) 31a is projected in the circular hole. Is formed. When the shaft 41 is inserted into the hinge hole 31, the notch surface of the shaft 41 restricts the movement of the projection 31a of the hinge hole 31 in the rotation direction, and the rotation of the hinge plate 32 is 60 degrees. Limited within range. Therefore, in the present embodiment, as shown in FIG. 7B, when the front door 2 is opened to the maximum, a part of the front door 2 does not come into contact with the wall surface located on the rear side of the substrate 5. That is, the central angle of the hinge hole 31 is set (the projecting piece 31a is projected) so that the maximum opening angle at the hinge portion is within 90 degrees.

The assembly of the electricity meter storage case 1 having the above configuration will be described.
First, after various devices including a watt hour meter or the like are installed on the substrate 5, the locking piece 20 is attached to the locking portion 21 with the rear opening edge of the cover member 4 being in contact with the outer periphery of the peripheral wall 22 of the substrate 5. The cover member 4 is attached to the substrate 5 by being locked. Next, the hinge hole 31 of the hinge plate 32 of the front door 2 is inserted into the shaft 41, and the hinge pin 40 is inserted into the shaft hole 33 and the small hole 42 from below, so that the front door 2 is opened to the case body 3. When it is attached as possible, the assembly of the electricity meter storage case 1 is completed. As for the opening and closing operation of the front door 2, if the front door 2 is pushed in the closing direction until the latching piece 37 is latched by the lock pin 43 in the step portion 6, the latching piece 37 is against the urging force. Is rotated from the normal position and is naturally hooked on the lock pin 43 to be in a closed state. If the user wants to open the door, insert a finger through the long hole 35 or the like and hold the left end of the front door 2 while pressing the lock mechanism 36 with the fingertip or the like. It rotates with the latching piece 37, the latching state of the latching piece 37 and the lock pin 43 is cancelled | released, and it can be made the state which can open the front door 2. FIG.

According to the electricity meter storage case 1 as described above, since the front door 2 is provided so as to cover at least the front surface of the case body 3 and at least the window 8, by closing the front door 2, Visibility of the rotor disk and display unit of the watt-hour meter can be blocked. That is, in order to visually recognize the rotor disk and the display unit, an operation of opening the front door 2 is necessary. Therefore, in the past, the above problem that the presence or absence of home was determined by the movement of the rotor disk or the like has occurred, but according to the watt-hour storage case 1 according to the present embodiment, the front door 2 is opened. If the above operation is not performed, the movement of the rotor disk or the like cannot be visually recognized. Therefore, the cases where the above problems occur can be reduced, and the crime prevention can be improved.
Further, a rubber cushioning member 38 is bonded over substantially the entire rear surface of the cover 2a of the front door 2, and the cushioning member 38 is in close contact with the front surface of the case body 3 when the front door 2 is closed. I am doing so. Therefore, it is possible to prevent rainwater or the like from entering between the front door 2 and the case body 3 and to perform the meter reading without worrying about the window 8 being soiled by rainwater or the like. In addition, by attaching the buffer member 38 to the rear surface of the covering portion 2a of the front door 2, it is possible to prevent a situation in which the front door 2 and the case body 3 come into contact with each other and are damaged due to the opening / closing operation. Effects such as improvement in durability of the meter housing case 1 and prevention of deterioration of aesthetics associated with use can also be achieved.

Further, a semi-cylindrical shaft 41 is provided on the case body 3, and a hinge plate 32 having a hinge hole 31 having a protruding piece 31 a is provided on the front door 2, and the shaft 41 is inserted into the hinge hole 31. The front door 2 is attached to the case body 3. Therefore, the movement of the projecting piece 31a in the turning direction by the opening operation of the front door 2 is restricted by the shaft 41, and the opening of the front door 2 beyond a predetermined opening angle is restricted. Therefore, in the electricity meter storage case 1 of the present embodiment, the front door 2 contacts the wall surface when the wall surface of the energy meter storage case 1 is installed by making the central angle of the hinge hole 31 smaller than 270 degrees. And the situation where the front door 2 and a wall surface will be damaged can be prevented.
Furthermore, since a separate stopper member that restricts the rotation of the front door 2 is not installed and used, problems such as an increase in the number of parts and loss of the stopper member do not occur. There is no need to provide an installation space or the like for installing the member, and the watt-hour storage case 1 excellent in aesthetics with few irregularities can be provided.

Further, the case main body 3 can be assembled by the engagement between the engagement piece 20 provided on the cover member 4 and the engagement portion 21 provided on the substrate 5, and the case main body 3 can be easily assembled. . Further, the cover member 4 is made of stainless steel, and a cut is provided on the lower surface of the cover member 4 to form the locking piece 20, thereby giving the locking piece 20 elasticity in the vertical direction. Therefore, the locking piece 20 and the locking portion 21 can be reliably locked, and the cover member 4 can be attached to the substrate 5 without using a separate mounting member. Effects such as improvement in workability can be achieved.
In addition, a peripheral wall 22 is provided along the outer periphery of the substrate 5, and the cover member 4 is attached to the substrate 5 with the rear surface opening edge in contact with the outer periphery of the peripheral wall 22. Therefore, it is possible to easily position the cover member 4 on the front surface of the substrate 5, to facilitate attachment work, and to prevent the cover member 4 from rattling or the like when attached to the substrate 5. It has a configuration.

  The configuration related to the electricity meter storage case of the present invention is not limited to the mode described in the above embodiment, and the configuration related to the case main body, the door body, the cover member, and the substrate is not limited to the present invention. As long as it does not deviate from the above, it can be changed as necessary.

  For example, in the watt-hour storage case described in the above embodiment, the door body is configured to be pivotally attached to the rear side edge of the case body and cover the entire front surface of the case body. If the provided opening is covered, the attachment part, shape, and opening / closing mechanism of the door body can be changed as appropriate, and the front surface of the case body is partially covered (for example, only the opening and its periphery). There is no problem even if the door body is a small door body, or the door body is pivotally attached to the front side edge of the case body or the opening portion is covered / opened by a sliding operation.

  Moreover, in the said embodiment, although it has set it as the structure which uses a buffer member also as a coating | coated member, you may make it provide a buffer member and a coating | coated member separately, for example, a coating | coated member only in the location corresponding to the opening part of a case main body. The cushioning member may be separately attached to an appropriate place where the cushioning member is easily damaged by contact with the case main body as the door body is opened and closed. Furthermore, there is no problem even if the covering member is not attached due to, for example, installation indoors, and the presence or absence of a buffering member can be selected depending on the material of the case body, the presence or absence of the covering member and the buffering member, and the mounting position. Etc. can be appropriately changed.

  In addition, in the case where the door body is attached to the shaft, a shaft and a hinge plate having a hinge hole may be provided on the upper and lower portions of the case body, respectively, and the shaft may be provided by a biasing means such as a spring. It may be possible to make it appear and fall freely, and the hinge plate may be attached and attached by operating the shaft so that the door body is attached to the case body. There is no problem even if the door body is provided with a shaft and the case body is provided with a hinge hole. Furthermore, it goes without saying that the central angle of the hinge hole, that is, the width in the rotation direction of the projection can be appropriately changed and designed depending on the door mounting position and the installation environment of the watt-hour storage case. The shape of the hinge plate can be changed as appropriate, such as forming the portion in a cylindrical shape.
