Description

[Detailed Description of the Invention] [Summary] A box with a square window of a predetermined size at the bottom and three claws at predetermined positions, four pressing seats and two fixing holes are symmetrically provided. To enable fixing of a wall-hanging box by simple combination with fixing hardware having a shape that can be easily divided at the center.

[Industrial application field]

The present invention relates to a box widely used in various electronic devices.

Recently, there has been an increasing demand for installing various electronic devices on walls in fields such as communication and information processing. Therefore, there is a need for a wall-mounted box fixing mechanism that facilitates the installation and fixation of various electronic devices installed on a wall surface.

[Conventional technology]

The currently most widely used method for fixing wall-mounted boxes is to attach a box 1 that has a predetermined number of mounting holes 1c to the bottom of the box with predetermined dimensions, as shown in Fig. 3.
The top cover 3 is attached via a hinge 4, and is attached to a hole of a predetermined size previously drilled in the wall in accordance with the position of the attachment hole 1c.

The installation method is as described in box 1 for wooden walls.
It is tightened from the inside with wood screws, but in the case of a concrete wall, a hole anchor (not shown) is driven into the hole in the wall and then tightened with an expansion bolt or the like from inside the rear box.

[Problem that the invention seeks to solve]

The problem with the conventional wall-mounted box fixing mechanism described above is that when fixing the box, you have to pick up screws such as wood screws or expansion bolts with your fingertips, carry them to the mounting hole at the bottom of the box, and use a tightening tool to tighten them. Since it is fixed by tightening, it becomes difficult to drill a hole in the wall surface for alignment with the mounting hole and to tighten the screws, which increases the time required for the installation work.

Further, a working space is required around the mounting hole in the box, which reduces mounting efficiency and requires a large box, which is a factor that hinders the reduction of installation costs and wall-mounted boxes.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wall-hanging box fixing mechanism that can easily and inexpensively fix the wall-hanging box.

[Means for solving problems]

The above problem was solved by drilling a horizontally elongated rectangular window 1a in the center of the bottom, and protruding inward from the bottom at the center of the upper edge of the corner window 1a, as shown in Figure 1. As shown in FIG. 2, a box 1 is provided with three claws 1b arranged close to each other, and a dividing slit 2c and a notch 2b are formed in the center of an elastic metal plate having a shape that allows the square window 1a to be inserted therethrough. Then, the fixing hole 2a for mounting on the wall and for rotation is inserted into the dividing slit 2.
c, and two pressing seats 2d for pressing the bottom surface of the box 1 are provided for each of the fixing holes 2a. This problem is solved by the wall-hanging box fixing mechanism of the present invention, which combines the fixing hardware 2.

[Effect]

That is, in the present invention, by inserting the fixing hardware 2 into the corner window 1a of the box 1 and pulling it down while being pressed against the wall, the fixing hardware 2 is inserted into the corner window 1a with the claw portion 1b formed at the center of the upper part of the corner window 1a. Notch 2
b and the dividing slit 2c, and the fixing hardware 2 divided by the claws 1b on both sides is inserted into the fixing hole 2.
When rotated in the direction of the dashed dotted line arrow around a, the bottom plate of the box 1 is pressed against the wall by the two pressing seats 2d and fixed, so the fixing holes 2a can be directly marked on the wall surface for alignment. This makes it easier to tighten wood screws, expansion bolts, etc.

Further, since the fixed hardware 2 rotates near the bottom surface of the box 1, its front surface can be used as a mounting area, so that the box 1 can be downsized and the wall hanging box and its installation cost can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a front view of the wall-hanging box fixing mechanism according to this embodiment.

As shown in the figure, a horizontally long rectangular window 1a is bored in the center of the bottom of the box 1, which is formed into a box shape with dimensions that can accommodate various electronic components. and this corner window 1a
3 at the center of the upper end and a predetermined distance away from it on both sides.
A wall-hanging box is manufactured in which a claw part 1b formed by bending a bottom plate to a predetermined dimension toward the front in the drawing is provided at several places, and a front cover 3 is attached to one side of the metal box 1 via a hinge 4.

Furthermore, as shown in Fig. 2, there is a rectangular dividing slit 2c of a predetermined size in the center as a metal fitting for attaching this wall-hanging box to the wall surface, and acute angles are provided on both upper and lower sides of the dividing slit 2c to facilitate dividing. The box 1 is provided with an elastic metal plate having a notch 2b through which the square window 1a of the box 1 can be inserted, and formed into a gentle chevron shape with the notch 2b on the upper end face as the apex. Claws 1b on both sides
Fixing hole 2a for mounting on the wall at the outer position
are drilled symmetrically with respect to the dividing slit 2c, and a pressing seat 2d pushed out in a bowl shape with these two fixing holes 2a as the center is inserted into the square window 1a at an interval slightly larger than the width in the vertical direction. Two fixed metal fittings 2 are formed.

Then, the fixed hardware 2 is floated slightly larger than the thickness of the bottom plate of the box 1, and loosely tightened to the wall surface with an expansion bolt, passed through the fixed hardware 2 at the corner window 1a of the box 1, pressed against the wall, and then pulled down. As a result, the fixed hardware 2 is divided at the central claw portion 1b as shown by the broken line in FIG.
is rotated in the direction of the arrow and can be easily fixed to the wall using the pressing seat 2d.

〔Effect of the invention〕

As explained above, according to the present invention, the wall-mounted box can be miniaturized with an extremely simple structure, the mounting position can be easily determined, there is no possibility that the mounting screws will fall out in the circuit, and the installation work time can be shortened. It is expected to be effective and is extremely useful industrially.
