Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a structure of a knockout provided at an end of a lighting fixture.

[0002]

[Problems to be solved by the device]

 After the knockout part, which was provided by pressing the center of the end of the fixture of the lighting fixture with a mold, was fitted into the fixture, it was easy to remove it.

[0003]

[Means for Solving the Problems]

 In order to provide a knockout at one end of the fitting of the lighting fixture, after pressing this part, when it is fitted, the part of the knockout is pressed by the mold to bend the knockout in an arc shape, and the surroundings of the knockout after fitting. To form a gap.

[0004]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. When punching the center of the end of the mounting bracket (1) of the lighting fixture to install the knockout (2), first press the center of the mounting bracket (1) as shown in FIG. 2 to knock out the knockout (2). To provide.

Next, as shown in FIG. 3, the knockout (2) that has been pressed against the mounting metal fitting (1) is fitted again, and this is fitted to the upper convex mold (3) and the lower concave mold shown in FIG. It is placed between (4) and pressed by the convex mold (3) to form a knockout (2) having an arcuate curved surface that is the same shape as both molds. As a necessary result, there are few contact parts around the knockout (2) as shown in FIG. 5, and a V-shaped gap (5) occurs, that is, the knockout (2) in the configuration of FIG. Since it is in contact with the metal fitting (1), it is extremely easy to take out the knockout (2) because there are few contact parts.

[0006]

[Effect of device]

 According to the present invention having the above-described configuration, the knockout portion is curved in an arc shape when fitted to the metal fitting as described above, and as a result, a gap portion is generated at the contact portion of both parties. Inevitably, there are few contact parts, and it is extremely easy to take out the product, as compared to the conventional one that makes full contact with no gaps. Is to have.
