Description

[Detailed description of the invention] The present invention is a casing in which a lid such as a back cover can be detachably attached to the casing without using screws, nails, bolts, hinges, adhesives, magnets, or other fasteners. The present invention relates to a mounting device for a lid body, etc.

Audio, video, medical, monitoring, automatic control, computers,
In view of the recent increase in demand for console-type cabinets used as operation consoles for power, measurement, or school broadcasting, they are manufactured in mass production using metal components such as aluminum sash and aluminum plates. The body frame is mainly made of aluminum profiles. Therefore, the case frame, aluminum decorative plate, back cover, etc. are all attached using screws or other fasteners, and screw insertion holes must be drilled in the case frame for each work. . In particular, the back cover has to be screwed on so that it can be attached and detached, which is a pain in the ass. Further, when the back cover is fastened in this manner, there is the inconvenience of having to remove and attach the fastener each time when repairing or inspecting equipment inside the cabinet.

In view of these circumstances, the present invention provides a device that allows the lid of the housing to be removably attached without using fasteners, thereby improving efficiency by saving labor and materials in manufacturing the cabinet. This reduces manufacturing costs, while also allowing the user of the cabinet to repair and inspect the interior without having to remove and install the fasteners.

An embodiment of the present invention will be described below based on the drawings. As shown in FIG. Reference numerals 1 and 2 are both elongated members, which are made of aluminum shapes, and are provided on the back 4 of a housing 3 such as a console cabinet as shown in FIG. The upper connecting member 1 has a substantially angle cross-sectional shape formed by cutting diagonally into the plane from one side to form a diagonal groove 5 in the molding direction, and is used at the top of the back 4 of the housing 3. The lower connecting member 2 is attached to the back 4 with a predetermined distance from the upper connecting member 1, that is, the width of the back cover 6. on the other hand,
The lower connecting member 2 has an H-shaped cross section and has upper and lower longitudinal grooves 7, 7'.

The back cover 6 has the above-mentioned upper connecting member 1 and lower connecting member 2.
It is a plate-shaped body having approximately the same length as the length of , and has an inclined edge 8 formed on its upper end side and a vertical edge 9 formed on its lower end side. The slanted edge 8 has an angle that allows it to fit into the slanted groove 5, and has an opening 8' through which the lower portion 5' of the slanted groove 5 can be inserted and removed. The vertical edge 9 is a bent piece that extends downward parallel to the plane of the back cover 6 so as to fit into the vertical groove 7. Although the main body of the back cover 6 is made up of two plates, it is not necessarily limited to this structure, and may have a cross section as shown in FIG.

To open and close the back cover 6, first fit the vertical edge 9 into the vertical groove 7, and then
(a), push the flat surface of the back cover 6 toward the housing (b), and press the inclined edge 8
By fitting (c) into the diagonal groove 5, the back cover 6 is irremovably held on the upper and lower surfaces of the diagonal groove 5 even if the housing 3 shakes vertically or in the front-rear direction. 1 and the lower connecting member 2 so as not to come off together with its own weight. On the other hand, when removing this back cover 6, first remove the inclined edge 8 from the diagonal groove 5 by lifting the whole thing away from the housing and obliquely upward, and then remove the vertical edge 9 from the longitudinal groove 7. It will come off easily if you remove it.

As described above, according to the present invention, the upper connecting member is notched diagonally in-plane from one side to form a diagonal groove in the molding direction, and the upper end of the back cover is formed with an inclined edge that can fit into the diagonal groove. At the same time, the vertical edge of the lower end part can be fitted into the vertical groove of the lower connecting member to fix it irremovably, but when the back cover needs to be opened, it can be forcibly pulled slightly outward and diagonally upward. It is preferable that there is no need to use a fastener at all. Therefore, fastener processing and attachment/detachment operations can be omitted, so this is an extremely useful device in manufacturing and using the casing.
