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

<First embodiment>

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

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, both ends are opened, and a device requiring waterproof treatment can 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 having a stepped end at one end and open at both ends.

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 firm connection with the tube 1100, and a cylinder having a relatively large diameter performs a stepped role and is fitted. You can guide the insertion depth of the cylinder.

That is, the O-ring flanges 1200 and 1300 are a combination of a cylindrical fitting portion 1210 having both ends opened and a disc shaped stepped portion 1220 having an open center having a larger diameter than the fitting portion. can

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

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, two O-ring insertion grooves are provided to allow double moisture blocking, and an oil groove is additionally provided to provide more complete moisture blocking.

That is, when only one O-ring is used in a waterproof module used in water, moisture is highly likely to occur inside the tube 1100 due to heat generated from the PCB and the battery inside the cylindrical tube 1100, and due to such moisture, the battery and PCB Because the board is more likely to short-circuit or corrode, it is preferable to use multiple O-rings for more effective watertightness.

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

In another embodiment, by using two O-rings and adding one more groove at the same time to inject oil (grease, etc.) through the injection holes in various directions, it is possible to primarily block the inflow of moisture through the oil, and Since one moisture can be blocked secondarily through two O-rings, it can be configured to block internal moisture.

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 having a larger diameter than the fitting portion and an open center.

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

In addition, the 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 opening of the O-ring flange is provided on the other surface of the stepped portion 1220, that is, on the 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 to prevent external leakage of the injected oil.

That is, if you want to separate the tube 1100 and the O-ring flanges 1200 and 1300, insert a tool into the opening auxiliary groove 1224 and separate using the lever principle, since easier separation is possible. A groove 1224 may be provided.

In addition, after oil is injected into the oil injection hole, an oil cap for blocking the oil injection hole may be provided to prevent external leakage of the injected oil, and the oil cap is provided in a screw shape and rotates through the oil. It may be configured to engage the injection hole.

On the other hand, the caps 1400 and 1500 are coupled to one end of the O-ring flange to prevent material inflow into the open hole of the O-ring flange, and are provided in a disk shape, opposite to the center of the circle on one side and the other on the outer circumferential surface Protrusions 1411 and 1412 may be provided in each direction, and a fastening corresponding hole 1420 may be included at 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, the maximum It is possible to provide a waterproof module that exhibits the watertight performance of
