Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device, and more particularly to the structure of an elongated bridge-shaped device body.

1 and 2 show a conventional example, in which a stabilizer 2 is attached to the bottom of an elongated bridge-shaped metal plate instrument body 1, and end caps 3 are attached to the openings at both ends of the instrument body 1. is the cut and raised piece 4
is inserted into the slit 6 in the side surface 5 of the instrument main body 1 and bent to be attached.

In this case, the main body 1 of the instrument is first formed with a slit 6 and then bent into a bridge shape, but the positioning accuracy of the slit 6 after bending is not good, and the end cover 3 may not be attached or may be loose. This may cause inconveniences such as

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

3 and 4 show an embodiment of the present invention, in which end caps 8 are fitted and attached to an elongated, bridge-shaped instrument body 7, covering the openings at both ends, and the inner bottom surface of the instrument body 7 is attached. 9 and ballast 10
is attached.

The device main body 7 is formed by bending a metal plate, and both side walls 11.11 are provided with two outwardly convex bending ribs 12, 12 along the elongated direction, and the side walls near both ends 11 is provided with a slit 13 for attaching the end cover 8 perpendicularly to the inter-folding ribs 12, 12, and both ends of the slit 13 extend to the middle of the folding ribs 12, 12, respectively.

The end cover 8 includes an end plate 14 that covers the opening of the instrument body 7, and a mounting piece 15 provided around the end plate 14 in a substantially cylindrical shape.
The mounting piece 15 is provided with an outwardly cut and raised piece 16 corresponding to the snot 13 of the instrument body 7.

The width of the cut-and-raised piece 16 is approximately equal to the width of the flat portion between the folding ribs 12 12 of the instrument body 7 .

Thus, the end cap 8 is attached to the instrument body 7 by fitting the attachment piece 15 into the instrument body 7, inserting the cut and raised piece 16 into the slit 13, and then bending the cut and raised piece 16.

At this time, the bent cut and raised pieces 16 are located between the bending ribs 12 and are positioned by the bending ribs 12.

Also, the shoulder 17 of the stabilizer 10 is inside the apex fold rib 12.

As described above, the slit 13 is provided longer than the width of the cut and raised piece 16 of the end cap 8, and is then bent to form the instrument body 7. The effective length of the slit 13, that is, the bending of the cut and raised piece 16, is made by the occasionally curved rib 12. The mounting position can be determined, and the end cover 8
It can be installed without wobbling.

Also, by setting the height of the eyebrows 17 of the stabilizer 10 to the position of the bending rib 12, even if the device body 7 is bent due to an impact, the stabilizer 10 and the device body 7 do not come into contact with each other, and a buffer batt is inserted during packaging. There's no need.

As described above, according to the present invention, the end cover can be attached without causing the inconvenience of rattling or not being attached.

Claims (1)

[Scope of utility model registration request] Two ribs protruding outward along the longitudinal direction are arranged side by side on both side walls of the elongated bridge-shaped instrument body, slits spanning both ribs are provided near both ends, and the end cap is attached to the circumferential mounting piece. 1. A lighting device that is fitted into openings at both ends of a device main body, and is attached by inserting a cut and raised piece provided on the mounting piece into the slit and bending it between the ribs between the two folds.
