Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a mounting device for a plurality of legs to be mounted on the bottom surface of an electrical device such as a receiving device for satellite broadcasting.

2. Description of the Related Art Conventionally, when attaching a molded resin leg to the bottom plate of an electrical device, the molded leg is fixed using screws.

A conventional leg attachment device is shown in FIG. 3 and will be described.

After inserting the screw 2 into the lower end recess 1 of the molded leg 1,
The molded legs 1 are fixed to the bottom plate 3 by inserting the above-mentioned screws 2 into the holes 5 from the bottom surface of the holder and tightening the screws 2 into the protruding parts 4. Legs can be attached.

Problems to be Solved by the Invention However, with the above configuration, screws are required to attach the molded legs, which requires more man-hours for installation, and since a protrusion is provided inside the bottom plate, it takes up space to install parts inside the casing. There is a problem in that there is a limit to miniaturization of the product due to restrictions, and a plurality of screws (four or more) must be prepared.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a leg attaching device which can eliminate such conventional drawbacks, allows easy attaching of legs with good workability, and is suitable for downsizing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a plurality of L-shaped cut-outs having saw blades in a part of the bottom plate in order to attach the legs to the bottom plate. The molded legs are press-fitted into the cut-and-raised portions to attach the legs.

Function: With the above-described structure, the present invention allows the legs to be attached to the bottom plate by simply press-fitting the legs into the L-shaped part of the bottom plate, and also reduces the number of screws that are required for conventional installation. The man-hours required for tightening the purifier can be improved.

EXAMPLE Hereinafter, a leg attachment method according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a state in which a molded leg is attached according to an embodiment of the present invention and a sectional view thereof, FIG. 2 is a sectional view of the same side, and FIG. 3 is an external view of an electric device.

FIG. 4 shows the state in which the electrical equipment legs A are attached, and are fixed to the bottom plate of the equipment at four locations. In FIG. 1.2, a portion of the bottom plate 6 is bent at a bent portion 7 to form an L-shaped raised portion 8 having a sawtooth portion 9.

Next, the molded leg 1 is attached to the cut-out portion 8 having the saw-toothed portion 9.
The saw blade shaped part 9 press-fits into the mounting hole 13 of the molded leg.
The molded legs 10 are attached to the bottom plate 6 by being fitted and fixed to the bottom plate 6. The 10 molded legs are provided with a recess 11 and a cut and raised part 8.
By extending the end portion 12 into the recess 11, a strong attachment condition can be ensured.

Effects of the Invention As described above, according to the present invention, ■ it is possible to press-fit any number of molded legs at the same time (in one go), improving the workability of attaching the legs, and ■ it is possible to reduce the number of screws. Therefore, there is no need to tighten screws, and there is no need to manage the purchasing or storage of machine screws, which has the effect of reducing costs and installation man-hours. ■Reliability is improved by reducing the number of parts by reducing the number of screws. ■The cut-and-raised part of the bottom plate has no convex part inside the bottom plate because it can be bent outward. (There were restrictions on the mounting arrangement of printed circuit boards and electrical components inside the bottom plate), the constraints on mounting and arrangement of printed circuit boards and electrical components inside the bottom plate have been improved compared to the conventional model, and this has a great practical effect on high-density mounting. , etc.
