Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof device, and is suitable for making a device having a drip-proof structure waterproof. Devices having a waterproof structure have been developed. FIGS. 1 and 2 show examples of conventional devices. Waterproof equipment has waterproof properties only in the equipment casing, and waterproof gaskets 2 are attached to the doors to maintain waterproofness.Also, the cables 3 that are connected to internal devices are waterproof. The connector 4 is used.

FIG. 3 shows the waterproof device 1 submerged in water 5. Note that the number 6 indicates the water surface.

However, with conventional waterproof devices, it is necessary to use a special part called a waterproof connector 4 at the cable entry port, and waterproof gaskets 2 must be used in movable parts such as doors, making the device expensive. There is a drawback. Furthermore, since only the device casing is made waterproof, there is a drawback that the material of the casing is fixed and damaged, and there is also a drawback that painting is limited because the device itself is made to have corrosion resistance.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and! The present invention aims to provide a waterproof device that is simple and inexpensive to construct.The present invention focuses on the fact that even if the container is turned upside down and submerged in water, water will only enter the container to a certain extent. A device having a droplet structure is covered with a dome with an open bottom, and the device is always installed in a place where air is present to provide a waterproof effect.Hereinafter, one embodiment of the waterproof device of the present invention will be described as a conventional example. The same parts will be explained using the same reference numerals and shown in FIG. 4, page 6.
' In FIG. 4, a drip-proof device 7 is covered with a box-like waterproof dome 8 having an open bottom to form a waterproof device.

This waterproof dome 8 is made of a steel plate.

In FIG. 5, a drip-proof device 7 is covered with a rounded waterproof dome 9 in the shape of a Japanese trade mark with an open bottom to form a waterproof device. In this example, the waterproof dome 9 is made of synthetic resin or the like.

FIG. 6 shows the embodiment shown in Figure 51 submerged in water. Inside the waterproof dome 9,
The water in accordance with the internal pressure of this waterproof dome 9 is
The drip-proof device 7 is installed in a place where air is always present, so that it has the same function as a conventional waterproof device.

According to this embodiment, the drip-proof device 7 is arranged in a waterproof dome 8 or 9.
By covering the drip-proof device 7 with a waterproof dome 8
Since it can be left in a place with constant air inside the straddle 9, it has a waterproof effect.

Moreover, since no consideration has been given to the fact that the main body of the drip-proof device will be submerged in water, the structure is good as long as it can prevent water droplets from falling on the device. is simple and inexpensive, and the waterproof dome 8 or Fi 9 covering the drip-proof device 7 is also simple and inexpensive in structure, which has the effect of making the waterproof device simple and inexpensive.

FIG. 7 shows another embodiment of the present invention, in which a ball 11 is attached by a ball mounting fitting 12 to the side surface of a waterproof dome 8 in which a drip-proof device 7 is attached to a housing support fitting 10. It has a similar structure.

The 11 poles can be moved up and down within the range between the stoppers 13. According to this embodiment, the ball 11
plays the role of a float and has the effect of minimizing the water pressure resistance of the waterproof dome 8, and other effects are the same as in the previous embodiment.

The $81 side is a further addition to the present invention! This shows another embodiment. In this embodiment, oil is injected into the waterproof dome 8 that houses the drip-proof device 7, and when the device is submerged in water, a film of oil 15 forms on the water surface 14 at the bottom of the waterproof dome 8, as shown in the figure. This has the effect of preventing water from evaporating into the waterproof dome 8 and suppressing the partial humidity of the device.

As described above, the waterproof device of the present invention has the advantage of being simple in structure and inexpensive.
