[0003] [Patent Document 1] JP 2006-269877 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, the above-mentioned flood prevention structure cannot cope with a situation in which the water level rises due to heavy rain or the like.
[0005] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a box for storing equipment that will not cause the stored equipment to become submerged in water, even if a situation occurs in which the water level rises due to heavy rain or the like. [Means for solving the problem]
[0006] In order to achieve the above object, the present invention provides a device storage box having a main body and a cover body attached to the main body so as to cover the main body from above, the main body having a base and a device installation section erected upward from an upper surface of the base. Therefore, only the space above the base is used as the installation space for the equipment.The base has a peripheral surface portion extending downward from the outer periphery of the upper surface of the base, while the cover body is formed in a box shape that opens only downward. A plurality of locking claws are provided on the inner surface of the cover body so as to protrude inwardly from the cover body, and a locking portion on which the locking claws can be locked is provided on the peripheral surface of the base. The outside of the recording surface and engaging the locking claw with the locked portion. The present invention is characterized in that the nozzle can be assembled to the main body in the above-mentioned state. Claim 2 The invention described in Claim 1 In the invention described in the item 1, a plurality of cylindrical portions extending in the vertical direction and opening downward are provided on the base, and at least one of the cylindrical portions is Installation It is characterized by being in communication with the space. Effect of the Invention
[0007] According to the present invention, the main body includes a base and an equipment installation section that is erected upward from the top surface of the base. Therefore, only the space above the base is used as the installation space for the equipment. The base has a peripheral portion extending downward from the outer periphery of the upper surface of the base, while the cover body is formed in a box shape that opens only downward and is attached to the main body while covering the outside of the peripheral portion. Therefore, even if the water level rises and exceeds the lower surface of the base, the air pressure inside the cover body prevents water from entering the inside of the cover body, particularly the equipment installation section located above the base, so that an equipment storage box can be provided with a simple structure that does not use waterproofing materials such as packing and does not cause the equipment installed in the equipment installation section to become submerged in water. Also ,mosquito Since the inner surface of the bar is provided with multiple locking claws that protrude inwardly of the cover body, and the peripheral surface of the base is provided with locking portions to which the locking claws can be locked, when the water level rises and a load is applied to the surface of the cover body in the inward direction of the cover body due to water pressure, the locking claws and the locking portions are more firmly locked together, making it difficult for the cover body to come off from the main body. This makes it possible to provide an equipment storage box whose water ingress prevention effect does not decrease as the water level rises. moreover, Claim 2According to the invention described in the above, the base is provided with a plurality of tubular parts that extend in the vertical direction and open downwards, so that when the water surface reaches the bottom surface of the base, the openings of the tubular parts suppress the waves that are generated on the water surface, and water is more reliably prevented from entering the equipment installation part. In addition, at least one of the tubular parts is Installation Since the cylindrical portion communicates with the space, it is possible to use the cylindrical portion as a wiring portion through which a cable connecting to an apparatus can be passed, thereby enabling the configuration to be streamlined.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a device storage box (hereinafter simply referred to as a storage box) according to one embodiment of the present invention will be described with reference to the drawings.
[0010] FIG. 1 is an explanatory perspective view showing a storage box 1. FIG. 2 is an explanatory perspective view showing the storage box 1 in a disassembled state. FIG. 3 is an explanatory perspective view showing the main body 2 from above. FIG. 4 is an explanatory perspective view showing the cover body 3 from below.

FIG. 7 is an explanatory view showing an enlarged view of region A in FIG. 6. FIG. 8 is an explanatory view showing a cross section of the main body 2 cut at the center in the left-right direction.
[0011] The storage box 1 comprises a main body 2 in which a circuit breaker 50, which is an example of equipment, can be installed, and a cover body 3 which can be attached to the main body 2 so as to cover it from above. The main body 2 is integrally formed with a base 4 which is rectangular when viewed from above, and a wall which is U-shaped when viewed from above and protrudes upward from both left and right side edges and the rear edge of the base 4, and a portion of the wall along the rear edge of the base 4 functions as an equipment installation section 5 on the front of which the circuit breaker 50 is installed, and portions along the left and right edges of the base 4 function as side walls 6 which surround the space above the base 4 (the installation space for the circuit breaker 50). Reference numeral 7 denotes an upper wall which extends forward from the upper end of the equipment installation section 5, and the upper walls 7, 7 are elastic and support the upper surface of the cover body 3 by pushing it up from below when the cover body 3 is attached.
[0012] The base 4 has a substantially horizontal top plate 11, a front plate 12 extending downward from the front edge of the top plate 11, left and right side plates 13, 13 extending downward from both left and right edges of the top plate 11, and a back plate 14 (shown in FIG. 8) extending downward from the rear edge of the top plate 11, and the front plate 12, the left and right side plates 13, 13, and the back plate 14 are formed as a continuous peripheral plate. The outer surfaces of the left and right side plates 13, 13 are flush with the outer surfaces of the left and right side walls 6, 6, and the rear surface of the back plate 14 is flush with the rear surface of the equipment installation section 5. In addition, in the space surrounded by the peripheral plates below the top plate 11, a plurality of ribs 15, 15... extending in the left-right direction and a plurality of ribs 16, 16... extending in the front-rear direction are arranged in a lattice pattern. Therefore, in this space, a plurality of vertically extending square tube portions 17, 17·· are arranged side by side in the front, rear, left and right directions with their openings facing downward. Furthermore, in the top plate 11 of the base 4, there are provided wire passage holes 18, 18·· which connect the interiors of certain square tube portions 17, 17·· with the space above the base 4 and through which cables L, L·· connected to the circuit breaker 50 are drawn from the outside into the storage box 1 through the corresponding square tube portions 17, 17··.
[0013] In addition, a locking step 19 capable of locking a locking claw 21 of the cover body 3 described below is provided at the lower end of the center of the front panel 12 in the left-right direction and at the lower end of the center of the left and right side panels 13, 13 in the front-rear direction. A guide recess 20 is provided on the surface of the front panel 12, extending in the vertical direction from the locking step 19 of the front panel 12 to the upper end of the front panel 12, for guiding the locking claw 21 when the cover body 3 is assembled. Also, on the outer surfaces of each side panel 13 and each side wall 6, a guide recess 20 is provided in the vertical direction from the locking step 19 of each side panel 13 to the upper end of each side wall 6, for guiding the locking claw 21 when the cover body 3 is assembled.
[0014] On the other hand, the cover body 3 has a front, a top, both left and right sides, and a back, and is formed in a box shape that is open only on the bottom. The vertical length of the cover body 3 is approximately the same as the vertical length of the main body 2 (the vertical length from the lower end of the peripheral plate of the base 4 to the upper walls 7, 7), and the bottom opening of the cover body 3 is approximately the same as the shape of the base 4 when viewed from above, so that the main body 2 can be stored in a state where the peripheral plate of the base 4 is covered from the outside. In addition, the lower ends of the front and both left and right sides of the cover body 3 are provided with locking claws 21 that protrude inward of the cover body 3.
[0015] In assembling the storage box 1 as described above, the circuit breaker 50 is installed on the front surface of the equipment installation section 5, and then the cover body 3 is assembled from above the main body 2 while guiding the locking claws 21, 21 into the left and right guide recesses 20, 20, and all the locking claws 21, 21... are locked into the locked stepped sections 19, 19.... This completes the assembly of the storage box 1 when the outside of the peripheral plate of the base 4 is covered by the cover body 3 and the lower end of the base 4 (the lower ends of the peripheral plate and the ribs 15, 16) and the lower end of the cover body 3 are substantially flush with each other. The storage box 1 assembled in this manner is then installed on an installation surface such as a wall using the metal fittings 30. The metal fittings 30 comprise a fixed plate 31 which is fixed to the installation surface, and a mounting plate 32 which protrudes forward from the lower end of the fixed plate 31 and on which the base 4 of the storage box 1 is placed. The fixed plate 31 can be fixed to the installation surface by screws, and the storage box 1 placed on the mounting plate 32 can be screwed in.
[0016] In the storage box 1 thus installed, even if the water level rises and exceeds the underside of the base 4, the air pressure inside the cover body 3 prevents water from entering the storage box 1, particularly the installation space of the circuit breaker 50. Furthermore, as the water level rises, the load exerted by the water pressure on the surface of the cover body 3 in the inward direction of the cover body 3, particularly the load on the lower part of the cover body 3 in the direction pressing it against the peripheral plate of the base 4, increases, so that the engagement between the locking claws 21, 21... and the locked stepped portions 19, 19... becomes stronger, making it difficult for the cover body 3 to come off. Therefore, the water ingress prevention effect of the storage box 1 does not decrease as the water level rises. Furthermore, on the underside of the base 4, multiple ribs 15, 16 are arranged in a lattice pattern, so that multiple angular tube sections 17, 17... that open downward are arranged side by side in the front, back, left and right directions. Therefore, when the water surface reaches the underside of the base 4, the openings of the angular tube sections 17, 17... suppress waves that arise on the water surface, and water is more reliably prevented from entering the installation space of the circuit breaker 50.
[0017] According to the storage box 1 having the above-mentioned configuration, the main body 2 includes the base 4 and the equipment installation section 5 erected upward from the upper surface of the base 4, and the base 4 has a peripheral panel consisting of a series of front panel 12, left and right side panels 13, 13, and a back panel 14 extending downward from the outer periphery of the upper surface of the base 4, while the cover body 3 is formed in a box shape that opens only downward and is assembled to the main body 2 in a state where it covers the outside of the peripheral panel. Therefore, even if the water level rises and exceeds the lower surface of the base 4, the air pressure inside the cover body 3 prevents water from entering the inside of the cover body 3, especially the equipment installation section 5 located above the base 4, so that the storage box 1 can be made with a simple configuration that does not use a waterproof member such as a packing, and does not cause the equipment installed in the equipment installation section 5 to become submerged in water.
[0018] Furthermore, the front panel 12 and both left and right side panels 13 of the base 4 are provided with latching steps 19, while the inner surface of the cover body 3 is provided with latching claws 21 that protrude inwardly from the lower ends of the front and both left and right sides of the cover body 3, and the cover body 3 can be assembled to the main body 2 by latching each latching claw 21 with the corresponding latching step 19, so that when the water level rises and a load is applied to the surface of the cover body 3 in the inward direction of the cover body 3 due to water pressure, the latching claws 21, 21... and the latching step parts 19, 19... are more firmly engaged, making it difficult for the cover body 3 to come off the main body 2. This makes it possible to provide a storage box 1 whose water ingress prevention effect does not decrease as the water level rises.
[0019] Furthermore, by arranging multiple ribs 15, 15... extending in the left-right direction and multiple ribs 16, 16... extending in the front-to-back direction in a lattice pattern in the space surrounded by the peripheral plate of the base 4, multiple angular tube sections 17, 17... extending in the up-down direction and opening downward are arranged side by side in the front-to-back and left-to-right directions.Therefore, when the water surface reaches the underside of the base 4, the openings of the angular tube sections 17, 17... can suppress waves that arise on the water surface, and water can be more reliably prevented from entering the equipment installation section 5.
[0020] In addition, a wire-passing hole 18 is provided at the upper end of a predetermined angular tube portion 17 on the top plate 11 of the base 4 to allow the angular tube portion 17 to communicate with the space above the base 4. Therefore, the angular tube portion 17 can be used as a wire-passing portion for passing the cable L connected to the circuit breaker 50, thereby streamlining the configuration of the storage box 1.
[0021] The configuration of the storage box of the present invention is not limited to the form described in the above embodiment, and the configuration of the main body and the cover body can be appropriately modified as necessary without departing from the spirit of the present invention.
[0022] For example, in the above embodiment, a top plate is provided as the base, but it is also possible to construct the base without a top plate (i.e., a base in which all tubular portions are open upward), and even with such a base, it is possible to achieve the effect of suppressing waves on the water surface and preventing water ingress. In addition, in the above embodiment, the engaging portions are provided at the front and both left and right sides of the peripheral surface of the base, but the engaging portions may be provided only on the left and right sides of the peripheral surface, or the engaging portions may be provided at the front and rear of the peripheral surface, and it goes without saying that the design can be modified as to where and how many engaging portions are provided.
[0023] Furthermore, there is no problem if the base is circular when viewed from above, and the shape of the base and the shape of the cover body that accompanies the shape of the base can be appropriately modified. In addition, in the above embodiment, a box for storing electrical equipment such as a circuit breaker is described, but the present invention can also be suitably adopted as a box for storing equipment other than electrical equipment.
