Description

[Detailed Description of the Invention] This invention relates to an improvement of a mounting device for control equipment such as an indicator light, a timer, an annunciator, and the like.

Generally, when a control device such as an annunciator having a flange and a body is mounted on a panel, the body 1a of the annunciator main body 1 is inserted from the front side of the mounting hole provided in the panel 2, as shown in FIG. 1
b is brought into contact with panel 2. Then, a mounting screw 3 with a vertical piece 4b of a shaped mounting bracket 4 screwed therein is interposed between the upper and lower walls of a recess 1d formed in the side of the body 1a from the side, and the mounting screw 3 is screwed with a screwdriver or the like. When turned, the locking piece 4a of the mounting bracket 4 housed in the recess 1d rotates and protrudes, and the mounting bracket 4 is pulled toward the panel 2 in accordance with the rotation of the mounting screw 3. The tip of the locking piece 4a of No. 4 presses and locks the panel 2. The main body 1 was attached to the panel 2 by similarly locking the attachment fittings 4 at other attachment points to the panel 2.

Conventionally, as shown in FIG. 2, this mounting bracket 4 has a vertical piece 4b having a through hole 4c with a screw thread on the upper part, and a locking piece 4a that locks on the panel, which are integrally formed in a substantially shape. The mounting screw 3 provided on the main body 1 was screwed into the through hole 4c, and the mounting bracket 4 was screwed onto the mounting screw 3.

However, since the above-mentioned mounting bracket 4 is integrally formed by casting, it has drawbacks such as a large amount of mold cost, a complicated work process, and an increase in cost.

This invention provides a proposed control equipment mounting device to improve the above-mentioned drawbacks.

This invention will be explained below based on the embodiment shown in FIG.

Reference numeral 5 denotes a mounting bracket, which is formed into a substantially shape by a vertical piece 5a and a locking piece 5b, and has a curved part 5c with a thread on the upper part of the vertical piece 5a, and a caulking part 5i approximately in the center. ing. And the curved portion 5c
are opposed to each other, and a cylindrical portion 5d is provided on the upper part of the vertical piece 5a.
The mounting bracket 5 is formed by integrally forming the lower part of the locking piece 5b.

Next, the manufacturing process of the mounting bracket 5 will be explained.
As shown in the figure, a plate material is punched into a substantially square shape by pressing, and curved portions 5c are formed in the same direction at both ends of the horizontal piece 5e, and holes 5f and protrusions 5g are provided at equal distances from the axis of symmetry. Then, as shown in FIG. 5, the vertical piece 5h is bent along the central axis of symmetry, and the protrusion 5g is caulked into the hole 5f. After that, the cylindrical part 5 formed by the curved part 5c
Form a thread on the inside of d.

As mentioned above, according to this invention, the mounting bracket can be manufactured by simply pressing the plate material, which reduces the mold cost, simplifies the manufacturing work, and greatly contributes to reducing costs. It is something to play.
