Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fishing lamp that prevents the base of the lamp screwed into the socket from loosening due to vibration or the like.

[Description of prior art]

Generally, when fishing for squid, etc., fishing lights are turned on to collect squid. In this fishing lamp, the lamp cap is screwed into the socket, and power is supplied to the lamp. Furthermore, the fishing boat on which this fishing light is installed is constantly vibrating from the diesel engine, etc., and there is a risk that the threaded connection of the lamp may come loose due to the vibration. Therefore, in conventional fishing lights, the lamp is screwed into the socket, a cylindrical band made of silicone rubber or the like is placed over the socket and the lamp, and both ends of the cylindrical band are attached to the lamp and socket with metal tightening bands. There is a type of lamp that is fixed in place, waterproofing the threaded part of the lamp and socket, and at the same time preventing the lamp from rotating to prevent it from loosening due to vibration. However, with this structure, the bulb part of the lamp is tightened with a metal tightening band, which has the disadvantage of damaging the lamp due to thermal expansion. The disadvantage is that the band requires a lot of effort to remove and attach.

[Summary of the idea]

The present invention was made to further improve the above-mentioned structure for preventing the lamp from loosening in the conventional fish-collecting light.A cylindrical lamp cover with an uneven outer periphery is fitted to the bulb part of the lamp, and the socket is fixed. A plurality of fixing members are pivotally supported in the socket so as to be swingable in the radial direction across the base insertion portion, and the free ends of the fixing members are made to face the uneven outer periphery of the lamp cover, and the plurality of fixing members are One ring is passed through a long hole drilled in the fixing member, and when the ring is moved, the free ends of the plurality of fixing members are pressed against or separated from the uneven outer periphery of the lamp cover. It is an object of the present invention to provide a fish-collecting light having a structure in which rotation of the lamp can be prevented or freed by changing the upper and lower rings very easily.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. Fig. 1 is an assembled cross-sectional view showing one embodiment of the fish-collecting light of the present invention, Fig. 2 is an external view of the fish-collecting light shown in Fig. 1 separated into a socket and a lamp, and Fig. 3 is a cross-sectional view of the fish-collecting light shown in Fig. 1. It is a top view showing the lamp cover of the fish-collecting light of the figure in detail.

In FIGS. 1 to 3, a socket 1 has a mounting member 3 disposed on the upper surface of an enameled metal case 2, and a base insertion portion 4 disposed inside the mounting member 3. This cap insertion part 4 is made of an insulator 5 such as porcelain.
A female screw-shaped electrode 6 and another electrode 7 on the screw shaft are arranged, and these electrodes 6 and 7 are connected to the socket 1.
A wiring 8 led out to the outside is connected. A socket cover 9 made of an elastic synthetic resin such as silicone rubber is disposed over the opening of the cap insertion portion 4. This socket cover 9
is cylindrical, and the bulb part 1 of the lamp 16 described later
A throat portion 10 that closely contacts the outer periphery of the tube 7 and a tongue portion 11 having a flexible cylindrical end portion are formed. Further, at the bottom of the case 2, a pair of L-shaped fixing members 13, 13 are provided across the opening of the cap insertion part 4.
They are swingable by shafts 12, 12 and are arranged to face each other. Note that the fixing members 13, 13
is swingable in radial directions centered on the opening of the cap insertion portion 4. And a pair of fixing members 1
The free ends of 3 and 13 are connected to a lamp cover 20, which will be described later.
It is constructed so that it faces the outer periphery of the building. Further, the fixing members 13, 13 are provided with round-shaped elongated holes 14, 14, and one ring 15 passes through these elongated holes 14, 14.

On the other hand, the lamp 16 has a cap 18 and an electrode 19 disposed at the tip of the bulb portion 17.
8 to the female threaded electrode 6 of the socket 2, and then connect the electrode 19 of the lamp 16 to the electrode 7 of the socket 1.
The lamp 16 is electrically connected by contacting the lamp 16 with the lamp 16. Then, the bulb part 1 of the lamp 16
A cylindrical lamp cover 20 made of an elastic synthetic resin such as silicone rubber is tightly fitted into the lamp cover 7 . A shoulder portion 21 is formed at the upper end of the cylindrical shape of the lamp cover 20, projecting inward, and an unevenness 22 parallel to the cylindrical axis is formed on the outer periphery of the cylindrical shape, as shown in FIG. There is. Note that it is desirable that the lamp cover 20 be fixed to the bulb portion 17 of the lamp 16 with an adhesive or the like.

The fishing light of the present invention has the above-mentioned configuration,
Assemble and separate as follows.

First, the ring 15 is inserted into the rectangular long holes 14, 14.
The fixing members 13, 13 are moved upward in FIG.
The free end of the tube is expanded as shown in FIG. When the lamp 16 is screwed into the socket 1 in this state, the cap 18 and electrode 19 of the lamp 16 are electrically connected to the internally threaded electrodes 6 and 7 of the socket 1. The throat 10 of the socket cover 9 is connected to a lamp 16.
The tongue part 11 of the socket cover 9 contacts the shoulder part of the lamp cover 20 to form a first waterproof structure.
A waterproof structure is constructed.

Here, the ring 15 is inserted into the square-shaped elongated holes 14, 14.
When moving downward in Fig. 1, the fixing member 1
The free ends of the lamps 3 and 13 come close to each other and come into pressure contact with the unevenness 22 on the outer periphery of the lamp cover 20, thereby preventing the lamp 16 from rotating in the screwing direction.

Next, when separating the lamp 16 from the socket 1, move the ring 15 upward in FIG.
The free ends of the ramps 16 are flared as shown in FIG. 2, allowing the lamps 16 to be freely pivoted and easily removed.

Therefore, the lamp 16 will not come loose from the socket 1 due to vibrations, etc., and the double waterproofing of the throat 10 and tongue 11 can ensure waterproofing. Furthermore, by simply moving the ring 15 up and down, the free ends of the fixing members 13, 13 are pressed into contact with or separated from the unevenness 22 on the outer periphery of the lamp cover 20, and the lamp 16 can be assembled and replaced quickly and easily. .

In addition, in the above embodiment, the fixing member 13,
Although the description has been made as a pair of two members 13, a plurality of members, such as three or four members, may be provided radially around the base insertion portion 4. Further, the elongated holes 14, 14 formed in the fixing members 13, 13 may be obliquely long elongated holes whose free ends are on the outside compared to the shafts 12, 12.

[Effect of idea]

As explained above, according to the fish-collecting light having the above structure, by moving the ring up and down, the fixing member provided on the socket is pressed into contact with or separated from the uneven outer periphery of the lamp cover that fits into the bulb of the lamp. Because it has a structure that allows you to prevent or free the lamp from rotating simply by moving the ring up and down,
The lamp can be assembled and replaced quickly and easily, and the assembled lamp does not come loose from the socket due to vibrations, etc., which provides excellent effects.
