Advantages and features of the present invention, and a method of achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

<Example 1>

1 is an exploded perspective view of the waterproof module according to the first embodiment of the present invention, FIG. 2 is a combined state diagram of the waterproof module according to the embodiment of FIG. 1, and FIG. 3 is an oil of the waterproof module according to the embodiment of FIG. A view for explaining an injection hole and a fastening hole, and FIG. 4 is a view showing a cap of the waterproof module according to the embodiment of FIG. 1.

Referring to FIGS. 1 to 4, the waterproof module 100 may include a tube 1100, O-ring flanges 1200 and 1300, and caps 1400 and 1500.

Here, the tube 1100 is provided in a cylindrical shape and has both ends open, and a device requiring waterproof treatment may be stored inside the cylinder. Electronic devices such as cameras and sensors may be stored inside the cylinder, and the tube 1100 may be made of a material having a transparent color for photographing outside the cylinder.

The O-ring flanges 1200 and 1300 may be fitted to both ends of the tube 1100 and may be provided in a cylindrical shape with open both ends having a stepped at one end.

That is, the O-ring flanges 1200 and 1300 may be configured in a form in which two cylinders having different diameters are combined for a solid coupling with the tube 1100, and a cylinder having a relatively large diameter serves as a stepped and is fitted. The depth of fitting of the cylinder can be guided.

That is, the O-ring flanges 1200 and 1300 are formed by a combination of a cylindrical fitting portion 1210 with open both ends and a disk-shaped stepped portion 1220 with a diameter larger than that of the fitting portion. I can.

In more detail, the fitting portion 1210 is provided in a cylindrical shape with both ends open, and a plurality of grooves may be provided parallel to each other on an outer circumferential surface thereof.

That is, the fitting portion 1210 is provided in a cylindrical shape, and the outer diameter is provided to be the same as the inner diameter of the tube 1100 so that the fitting portion 1210 is fitted to both ends of the tube 1100 do.

At this time, the fitting portion may be provided with a plurality of grooves on the outer circumferential surface to improve watertight performance, and the plurality of grooves contain O-ring insertion grooves 1212 and 1213 and oil into which the O-rings are inserted in order to improve watertight performance. It may include an oil groove 1211 to more effectively block moisture by injection.

At this time, two O-ring insertion grooves are provided to enable double moisture barrier, and an oil groove is additionally provided to provide more complete moisture barrier.

That is, if only one O-ring is used in the waterproof module used underwater, there is a high possibility that moisture is generated inside the tube 1100 due to heat generated from the PCB and the battery inside the cylindrical tube 1100, and due to this moisture, the battery and the PCB Since there is a high possibility of short circuit or corrosion on the board, it is preferable to use several O-rings for more effective watertightness.

However, if the O-ring is used excessively, the length of the fitting part 1210 becomes longer, and it becomes difficult to insert the fitting part 1210 into the tube 1100, so the number of O-rings depends on the degree of water tightness required Can be adjusted.

In another embodiment, by using two O-rings and adding an additional groove at the same time, oil (gurise, etc.) is injected through the injection ports in various directions, so that the inflow of moisture through the oil can be prevented, and the oil passes through. One moisture can be configured to block the moisture inside because it can be prevented through two O-rings.

On the other hand, the stepped portion 1220 is coupled to one end of the fitting portion, it may be provided in the shape of a disk with an open center having a larger diameter than the fitting portion. Accordingly, the diameter of the stepped portion may be larger than the outer diameter of the tube 1100 to guide the fitting portion 1210 so that it is no longer inserted into the tube 1100.

More specifically, on one surface of the stepped portion 1220, that is, a surface opposite to the surface in contact with the tube 1100, a plurality of fastening holes 1221 for fastening with the cap on a surface coupled to the cap, A plurality of oil injection holes 1222 for oil injection and a circular O-ring groove 1223 for maintaining airtightness with the cap may be provided.

Therefore, when oil is injected into the oil groove 1211 through a plurality of oil injection holes 1222 provided on one side of the stepped portion, the oil fills the oil groove 1211, and the filled oil fills the tube 1100. The voids that may exist on the inner surface and the outer surface of the fitting part 1210 are filled, so that more perfect watertightness may be possible.

In addition, caps 1400 and 1500 are coupled to one surface of the stepped portion to completely block communication with the outside, and an O-ring groove 1223 may be provided for more complete blocking to enhance adhesion.

In addition, an opening auxiliary groove 1224 for assisting the opening of the O-ring flange is provided on the other surface of the stepped portion 1220, that is, a surface in contact with the tube 1100, and after oil is injected into the oil injection hole, It may further include a screw-shaped oil cap that prevents the outflow of the injected oil.

That is, in the case of separating the tube 1100 and the O-ring flanges 1200, 1300, easier separation is possible than when a tool is inserted into the opening auxiliary groove 1224 and separated using the lever principle. A groove 1224 may be provided.

In addition, after the oil is injected into the oil injection hole, an oil cap may be provided to block the oil injection hole in order to prevent the oil from leaking to the outside, and the oil cap is provided in a screw shape and rotates It may be configured to engage with the injection hole.

On the other hand, the caps (1400, 1500) are coupled to one end of the O-ring flange to prevent material inflow into the opened hole of the O-ring flange, and provided in a disk shape, opposite to the center of the circle on one side and the other side of the outer circumferential surface. Protrusions 1411 and 1412 may be provided in each direction, and a fastening-corresponding hole 1420 may be included in a position corresponding to the plurality of fastening holes.

As described above, according to an embodiment of the present invention, by using an O-ring flange and a cap including a plurality of O-ring insertion grooves and O-ring grooves at both ends of the cylindrical tube 1100 to maintain watertightness, It can provide a waterproof module that shows the watertight performance of.
