Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a plate body such as a front plate of a switch box for an electronic chestnut machine, which is easy to attach.

As shown in FIG. 1, conventionally, a front panel 1 of a switch box body for an electronic chestnut machine has a bent portion 3 formed by bending a lower plate 2 of the box body upward.
0 with screws 40, the assembly requires a large number of man-hours, and it is troublesome to remove the front plate 1 in order to repair the internal switch.

The present invention aims to eliminate the above-mentioned drawbacks of the conventional technology, and an example of its implementation will be explained with reference to FIGS. 2 to 4.

Figure 2 is a perspective view from below of the box housing the switch with the front panel removed, which will be described later. 2 is the lower plate, and 3 is the inwardly directed protrusion provided at both ends of the front edge of the lower plate. Piece 4 is a locking piece of the front plate provided in the middle of the front edge of the lower plate, and the upright pieces 4/ , 4/ have hook-shaped tips opposing each other at a small interval.
5 is an upper plate, and 7 is a side plate connected to the upper plate 5 and the lower plate 2.

The front plate 1 shown in FIG. 3 is provided with a recess 1' at a position corresponding to the locking piece 4. They are made to be approximately the same length or larger.

Therefore, in order to install the front plate 1 so as to close the space formed by the upper plate 5, lower plate 2 and side plate 7 as shown in FIG. It engages with the recess of 3.

Then, when the middle part of the front plate 1 is pressed downward, the recess 1'
passes through the tip of the locking piece 4, and the front plate comes into contact with the edge of the lower plate 2 and stops.

Since the width of this recess 1' is slightly shorter than the width of the tip of the locking piece 4, the recess 1' passes through the tip of the locking piece, and after that, the front plate 1 stands upright. It is locked by the hook-shaped portions of the pieces 4' and 4'' and does not easily escape to the outside.

On the other hand, the upper edge of the front plate 1 is fitted between two bulges 6 provided on the upper plate 5 of the box body, and its position is fixed.

If the length of the front plate 1 is made slightly shorter than the length between the lower parts of the protruding pieces 3 of the lower plate 2, or if the width of the recess 1' of the front plate is made shorter than the width of the tip of the locking piece 4. If it is larger than this, use a screwdriver or the like to widen the space between the upright pieces 4/, 4/, or bend the protruding piece 3 and press the front plate against it.

In this embodiment, the upper edge of the front plate is fitted between the two bulges 6 of the upper plate of the box body to lock the front plate to the upper plate. Of course, the plate may also be formed in the same way as the lower edge and the lower plate.

As described above, the present invention has two protruding pieces facing inward at both ends of the edge of the plate forming the box body, and two upright pieces having hook-shaped tips facing each other with a small gap in between. A locking piece is provided, a recess is provided at the edge of another plate disposed perpendicularly to the plate, and both ends of the other plate are engaged with the recess of the protruding piece, and the recess is Since it is locked to the hook-shaped portion of the locking piece, the number of assembly steps is reduced compared to conventional ones, and the plate body can be easily removed.
