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 groove 31 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 to the lower fitting part. This is intended to prevent rainwater from entering the inside of the box body 2 by allowing it to flow out through a drainage port 73 formed by a notch in the outer side 31b forming the box body 2.

However, in the conventional box body 2, as shown in FIG. 3A and B, the protrusion 41 provided on the cover 4
Since it is cut above the circular arc portion 31c formed on the inner side 31a of the groove 31 provided in the groove 31, drainage is poor in the vicinity of the drain port 73 in the installed state, and the above-mentioned convex portion is lower than the periphery of the circular arc portion 31c. There is a risk that water that has moved to the lower end 41a of the riser 41 may enter the box 2, resulting in insufficient protection of the measuring instrument 1 housed inside.

The present invention eliminates the above-mentioned drawbacks of the conventional products and provides a device storage box that is highly waterproof.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 4. The difference between the figure and FIGS. 1 and 3 is that the lower end 41b of the protrusion 41 provided on the cover 4 is extended to the arcuate lower end outer circumferential surface 8 of the cover 4 as shown.

In such a configuration, rainwater that has entered the water passage 7 flows from the upper water passage 71 to the side water passage 72, moves to the lower end 41b of the protrusion 41 provided on the cover 4, and then is drained. It is dripped from the mouth 73 to the outside. Therefore, unlike the conventional case, rainwater does not enter into the box body 2 from around the arcuate portion 31c, and the measuring instrument 1 can be reliably protected from rain.

As described above, according to the present invention, it is possible to protect measuring instruments and the like from rainwater, and it is possible to obtain an equipment storage box having a reliable waterproof structure.

Claims (1)

[Claims] 1 Consisting of a base having a groove or projection and a cover having a projection or groove that fits into the groove or projection of the base, and a passage formed between the groove and the projection. In an equipment storage box body having a water channel and a discharge port formed by a notch at the lower end corner of the outer side forming the groove and communicating with the water flow channel, the lower end of the protrusion is connected to the box body. A device storage box body characterized by extending to the outer peripheral surface of the lower end.
