Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watertight lid for a container which requires watertightness and an improvement of a bonden buoy for fishing using the watertight lid.

[0002]

2. Description of the Related Art Conventionally, a lid of a cylindrical container which needs to be watertight is kept watertight by sandwiching a packing such as an O-ring between the flange of the container and the lid and tightening it with a few bolts (see FIG. 8). Made the container and the lid screwed together, and kept the watertightness through the watertight O-ring between the container and the lid. It was also called the lid for the battery room of the Bondenbuy for fisheries.

[0003]

When bolting a lid to a conventional flange, the nuts of several bolts must be tightened or loosened with a spanner, and when the container and lid are screwed together, The diameter of the screw part becomes large, and a large force is required for turning when tightening or loosening, and a special tool is often required. Particularly in the case of the battery room of the bond buoy for fishing, since the storage battery is taken out and charged every day, the work of opening and closing the lid of the battery room requires much labor.

The present invention eliminates the need for special tools
The lid can be opened and closed by simply loosening or tightening one nut, and it is easy to loosen or tighten the nut by hand without using a spanner. is there.

[0005]

To achieve this object, according to the present invention, a lid plate slidably inserted into the cylindrical body of the container to be sealed and a bolt watertightly provided upright in the center of the lid plate. , An umbrella-shaped stopper made of an elastic material that is located so that the outer edge of the umbrella-shaped stopper is in contact with the lid plate and the top is fitted into a bolt and slidably inserted into the cylinder, and the top of the umbrella-shaped stopper fitted into the bolt A watertight lid consisting of a stopper that is in contact with and locked to the cylinder, and a nut that is screwed into the bolt from the outside of the stopper.Tightening the nut causes the outer edge of the umbrella-shaped plug to bulge out and adhere to the lid plate and the inner surface of the cylinder. It is a watertight lid that is kept watertight.

[0006] In addition, a lamp unit on the top of the pillar, a buoyant body in the middle,
A bonden buoy having a cylindrical battery chamber at its lower end, wherein the bottom of the battery chamber is sealed with the watertight lid.

[0007]

[Function] When sealing the lid of the tubular container, insert the lid plate into the tubular body, insert the umbrella-shaped plug into the bolt, and then pass the stopper through the bolt from the outside to lock the outer edge of the stopper to the tubular body. ,
When the nut is screwed into the bolt from the outside and tightened, the umbrella plug is compressed between the lid plate and the stopper, and the outer edge of the umbrella plug is crimped to the lid plate and bulges outward to the inside of the cylinder. It is crimped to keep the watertightness and the position is fixed by the stopper. Since the umbrella plug is made of an elastic material, the tightening force of the nut does not require a large torque, and it can be easily rotated by hand without using a spanner, and the opening and closing of the lid is extremely easy.

If the battery compartment lid is a bond buoy using the lid of the present invention, the lid can be opened and closed easily by hand without using any tool, and by simply opening and closing one nut. The lid can be opened and closed, making it extremely easy to take out and install the storage battery even when using many bond buoys.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway front view of a bond buoy using a watertight lid embodying the present invention. Reference numeral 1 is a watertight lid of the present invention, 2 is a battery chamber that is kept watertight by the watertight lid 1, 3 is a cylindrical body that constitutes the wall of the battery chamber, 4 is a storage battery, 5 is a pillar, 6 is a buoyant body, 7 Is a lantern. In this example, it is a lamp using a fluorescent lamp as a light source. During the fishing season, the storage battery is recharged every day by opening the watertight lid.

FIG. 2 is a central longitudinal sectional view of the lower portion of the battery chamber, FIG.
FIG. 3 is a view taken along line AA of FIG. 2. The watertight lid 1 is composed of a lid plate 8, bolts 9, an umbrella-shaped plug 10, a stopper 11, and a bar nut 12. The head of the bolt 9 is welded all around the cover plate 8 to keep it airtight. In this example, the rod nut 12 that is easy to tighten is used for tightening, but an ordinary nut may be used.
The umbrella-shaped plug 10 is formed of an elastic material such as rubber.

FIG. 4 is an explanatory view showing a state in which the watertight lid is closed by tightening the rod nut 12, and the arrow indicates the umbrella plug 10 and the lid plate 8.
Indicates the direction in which pressure is applied, and this pressure causes the umbrella-shaped plug 10 to expand uniformly over its entire circumference, so that water tightness with the tubular body 3 is maintained. A
The part is enlarged to show the sealing part. 13 is a cushion rubber, and 14 is a distance piece.

FIG. 5 is a partially cut front view showing details of the watertight lid, and FIG. 6 is a bottom view. The stopper 11 is locked (released in the drawing) or released from the cylindrical body 3 by turning only the arrow in FIG.

FIG. 7 is an explanatory view showing a state in which a bond buoy is attached to the flow net 15.

FIG. 8 is a view showing an example of a conventional example. Since the O-ring 16 is used and the lid is fastened with a plurality of bolts, the workability is poor, and if the bolts are partially tightened, water will leak. There was a fear of becoming.

In this embodiment, the watertight lid of the present invention is used as the bottom lid of the battery compartment of the bond buoy, but it goes without saying that it can also be used as the top lid of the hatch of the power supply compartment such as the buoy. .

[0017]

[Effect] If the watertight lid according to claim 1 is used, the lid can be easily opened and closed by loosening or tightening only one nut without using a special tool, and a plurality of conventional bolts can be used. It provides a watertight lid that has excellent workability and is free from the risk of inundation due to one-sided tightening.

If the bond buoy using the watertight lid according to the second aspect is used, the lid can be easily opened and closed by simply turning one nut by hand without using a tool. This makes it extremely easy to take out or install the storage battery for charging, and there is no risk of water leakage due to one-sided tightening.
