Description

[Detailed Description of the Invention] The present invention relates to a lighting device, and its purpose is to make it possible to easily adjust the mounting direction of a globe that is screwed onto the main body.

Conventionally, lighting equipment has a globe attached to the main body surrounding the lamp, but if the main body and the globe are non-circular and are screwed together, the direction of the outer shape of the main body and the outer shape of the globe may be different when screwed in. In order to solve this problem in appearance, the glove was screwed in and then slightly retracted to match the direction of the main body, but in this state, the screw was not fully screwed in. There was a risk that it would shrink and fall due to vibration, etc.

The present invention has been made in view of the above points, and will be explained below based on the drawings.

1 to 6 show an embodiment of the present invention, the main body of which fits into a substantially rectangular substrate 1 and a hole 3 provided at the center of the substrate 1 and having an inner flange 2 with a concave shape around the periphery. A packing 4, a substantially cylindrical outer shell 6 that is attached to the packing 4 at the bottom and has an inwardly convex mounting base 5 formed in the center of the bottom, a screw 7 curved on the outer periphery and a hole 8 in the center of the bottom. A holder 10 having a tongue piece 9 protruding from one part of the hole, a socket base 12 having a pair of cut and raised protrusions 11 on the back surface that fit into the hole 8 of the holder 10, and a socket base 12. and the liquid spring washer 13 sandwiched between the holder 10 and the socket base 1.
The lamp 15 attached to the lower surface of the lamp 12 with a screw 14 is screwed into the socket 16, and the socket base 12 is screwed with the screw 19 with the protruding piece 11 inserted into the spring washer 13 and the hole 8 of the holder 10. The holder 10 is held between the socket base 12 and the outer shell 6 via a spring washer 13, and the tongue piece 9 comes into contact with the protruding piece 11 of the socket base 12. It can be rotated freely within the range that it does not move.

The globe 18 is a substantially rectangular parallelepiped made of a translucent material such as glass, and has a neck 20 protruding from its upper surface with a screw 19 on its outer periphery, and an elastic packing 21 is attached to the base of the neck 20. .

To attach such a glove to the main body, the lamp 15 is inserted into the interior through the neck 20, and the holder 10 is screwed together with the screw 19 of the neck 20.

At this time, the holder 10 is prevented from rotating with the tongue piece 9 in contact with one of the projecting pieces 11 of the socket base 12, and the glove 18 can be screwed in.

After the holder 10 is screwed in further and the gasket 21 comes into contact with the lower end surface of the outer shell 6, the holder 10 is pulled down by bending the spring washer 13, and the screwing is completed at the bending limit of the spring washer 13.

At this time, if the direction of the glove 18 does not match the direction of the main body 1, by twisting the glove 18 back, the glove 18 and the holder 10 rotate together due to frictional force, and the screws 7 and 19 are aligned without loosening. can be done.

The present invention is constructed as described above, and is a lighting device in which a globe 18 also having a non-circular shape is screwed onto the device main body having a non-circular outer shape which is cut out from the outer shell 6 etc. of the substrate 1.
0 has a hole 8 with a protruding tongue piece 9 formed in a part thereof, and a plurality of protrusions 11 are formed on the socket base 12.
The socket base 12 is attached to the instrument body by fitting the protruding piece 11 into the hole 8 of the holder 10 so as to be approximately inscribed in the hole 8 of the holder 10.
0 between the instrument body and the socket base 12, the tongue piece 9 is placed between the protruding piece 1
The holder 10 is rotatable within a range that does not come into contact with the socket base 12 and the holder 10, and the holder 10 is urged inward by a spring such as a spring washer inserted between the socket base 12 and the holder 10.
0 can move forward and backward against the elasticity of the spring, so when the glove 18 is screwed onto the instrument body, when the glove 18 is screwed onto the screw 7 of the holder 10, the tongue piece 9 of the holder 10 is attached to the socket base 12. The glove 18 is screwed into the holder 10, and the glove 18 and the instrument body are brought into close contact with the gasket 21 to form a waterproof structure, and when the glove 18 is screwed together, the spring is bent so that the holder 10 is in close contact with the socket base 12, and if the mounting direction of the glove 18 and the instrument body is misaligned with the screwing of the glove 18 and the holder 10 completed, the glove 18 can be moved in the opposite direction. When the screw is unscrewed, the tongue piece 9 of the holder 10 is released from contact with the protruding piece 11 of the socket base 12, and the holder 10 rotates together with the globe 18 due to its frictional force.
The mounting direction of the glove 18 and the instrument body can be matched without changing the screwing state of the two.
