Description

[Detailed Description of the Invention] For example, when installing a measuring instrument outdoors,
This invention relates to an improvement of an equipment storage box used for the purpose of protecting measuring instruments from wind and rain.

Conventionally, there has been a box of this type as shown in FIG. In the figure, 1 is a meter for measuring the amount of water or electricity; 3 is a base that is open on one side and has a groove 31 on the periphery of the opening; 4 is open on one side;
A protrusion 4 that fits into the groove 31 on the peripheral edge of the opening end
1 is a cover, 5 is a screw for fixing the cover 4 to the base 3, 32 and 42 are protrusions provided integrally with the base 3 and the cover 4, and 61 is the protrusion 3.
2, 42, and the protrusion 32, 4
2. The hinge 6 is composed of the shaft 61, and this hinge 6
The cover 4 is rotatably supported by the base 3. 2 is the base 3, cover 4, screw 5,
This is a box body for storing instruments, which is composed of a hinge 6.
The cover 4 rotates about the shaft 61 and the base 3
The base 3 is coupled to the base 3 by fitting the protrusion 41 into the groove 31 .

When rain falls on the upper part of the instrument storage box 2 in such a coupled state, some of the water tends to enter the inside of the box 2 through the gap between the fitting parts. At that time, the drainage provided at the lower fitting part once enters the upper side passageway 71 of the passageway 7, which is formed by the difference between the depth of the groove 31 and the height of the protrusion 41, and passes through the side passageway 72. This is intended to prevent rainwater from entering the box body 2 by allowing it to flow out through the hole 73.

However, in the conventional box body 2, as shown in FIG. 3, the groove 31 provided on the base 3 and the protrusion 41 provided on the cover and fitted into the groove 31 are closely engaged with each other on the side surfaces. Since the water passage 7 is cut off from the outside air, water that has entered the water passage 7 tends to stay in the upper water passage 71 and the side water passage 72, and may eventually overflow into the box body 2. . Therefore, there was a drawback that the measuring instrument 1 housed inside could not be completely protected.

The present invention aims to eliminate the above-mentioned drawbacks of the conventional ones and provide a device storage box with excellent waterproof effects.

Hereinafter, the second and fourth embodiments of the present invention will be explained.
This will be explained based on the diagram. Figures 1 and 3
The difference from the one in the figure is that as shown in the figure, an air hole 8 is bored in a part of the outer piece 31a of the groove 31 provided in the base 3, and a part of the inside of the side passageway 72 is communicated with the outside air. It is something.

Therefore, in such a configuration, rainwater that has entered the upper side waterway 71 flows from the upper side waterway 71 toward the side waterway 72, and then flows through the drain port 73.
This makes it easier for the liquid to be discharged to the outside. Therefore, even if rainwater enters the water passage 7, there is no fear that it will enter the box 2, and the measuring instrument 1 can be reliably protected from rain. Note that there is no problem even if a plurality of the air holes 8 are formed.

As described above, according to the present invention, since rainwater that has entered the water passage can be reliably discharged outside the box, there is no fear of rainwater entering the box, and a highly reliable equipment storage box can be provided. It is.

[Brief explanation of drawings]

Figures 1A and 1B are views showing conventional measuring instrument storage boxes, Figure 1A is a cutaway side view, Figure 1B is a partially cutaway front view, and Figure 2 is the invention. FIG. 3 is an enlarged cross-sectional view taken along the line A-A showing the conventional example, and FIG. 4 is an enlarged cross-sectional view taken along the line B-B showing the essential parts of the present invention. In the figure, 3 is the base, 31a is the outer side, 4
is a cover, 7 is a water passage, and 8 is an air hole. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] 1. Equipment storage comprising a base having grooves or protrusions, and a cover having protrusions or grooves that fit into the grooves or protrusions, and forming a passageway between the grooves and protrusions. 1. A box for storing equipment, characterized in that at least one air hole is bored in a part of the outer side of the groove to communicate the water passageway with outside air.
