Description

[Detailed description of the invention] The present invention relates to a lighting device in which an arm pipe is connected to the main body and a lead wire is passed through the arm pipe, and particularly relates to an improvement in the structure for connecting the arm pipe to the main body. It is something.

FIG. 1 shows an incandescent lamp pendant. In an incandescent lamp pendant, a lead wire is passed through an arm pipe 4 connected to a main body 3 consisting of an upper part 1 and a lower part 2, and a switch 6 on a handle part 5 is used. In order to electrically connect the arm pipe 4, a structure as shown in FIGS. 2 and 3 has conventionally been adopted as a mounting structure for the arm pipe 4.

. To explain the structures shown in FIGS. 2 and 3, first, the structure shown in FIG.
．． 7, which is attached to the lower body 2 by sandwiching the lower body 2, but this structure has drawbacks such as high cost and time required since two nuts 7.7 are used.

In addition, the structure shown in FIG. 3 has a part cut out at the tip of the arm pipe 4 to take out the lead wire 8,
is fixed to the main body 3 by screws 9 fixed to the lower part 2 of the main body, but this structure has disadvantages of high processing costs and difficulty in taking out the lead wire 8.

The present invention has been made in view of the drawbacks of the conventional structure described above, and it is an object of the present invention to provide a lighting fixture that eliminates these drawbacks.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 4 and 5, which illustrate the embodiment.

The following examples are based on the incandescent lamp pendant shown in Figure 1, and in Figures 4 and 5, the same parts as in Figures 1 to 3 are designated by the same symbols. I will explain.

Figure 4 shows an embodiment of the present invention, and is an enlarged sectional view of a portion corresponding to part A in Figure 1, and Figure 5 is an enlarged sectional view of the embodiment of the same location. be.

First, the embodiment shown in FIG. 4 will be explained. In this structure, a round hole 11 is provided on the side surface of the end of the arm pipe 4 that is inserted into the pipe insertion hole 10 provided in the lower part of the main body 2. 11, a spring pin 12 is passed through the arm pipe 4 inserted into the pipe insertion hole 10 of the lower body 2, and this spring pin 12 is connected to the rib 13 provided on the upper body 1.
The arm pipe 4 is connected and fixed to the main body 3 by pressing down when fixing the upper main body 1 to the lower main body 2 with screws 9.

In this structure, by using a spring pin 12 with a small diameter, the space inside the arm pipe 4 can be widened, and the lead wire 8 can also be easily passed through.

Next, the embodiment shown in FIG. 5 will be explained.
In the illustrated embodiment, the spring pin 1 is connected to the rib 13 on the main body 1.
However, in the embodiment shown in FIG. 5, the arm pipe 4 is connected and fixed to the main body 3 by pressing the end face of the arm pipe 4 with the rib 13 on the main body 1.

In the embodiments shown in FIGS. 4 and 5, various shapes can be considered for the ribs 13 provided on the main body 1, such as those formed integrally with the main body 1, and those formed separately with a bottom shape. In short, any material that fulfills the above functions, such as an integrally formed material, a pin-like material, or a rib-like material, is suitable.

In addition, in FIG. 1, 14 is a lamp.

As mentioned above, the present invention provides a lighting device in which an arm pipe is connected to the main body and a lead wire is passed through the arm pipe, and the main body is constructed from above and below the main body, and the arm pipe is connected to the main body. By inserting the pipe into the bottom of the main body, inserting a spring pin into the side of the end, and pressing this spring pin or the end of the arm pipe on the main body,
The arm pipe is connected and fixed to the main body, and this structure allows the arm pipe to be processed easily and inexpensively, making it cheaper and easier to assemble than conventional structures.
