Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a cabinet for various electrical equipment, and more specifically, a cabinet body having four sides and a bottom surface, and a cabinet body that is combined with this cabinet body and has a top surface of the cabinet body. and a cover member for covering the device.

[Technical background of the invention] In electrical equipment such as audio tuners, amplifiers, and video tape recorders, each component is a cabinet made of a synthetic resin molded product with an integrally formed outer peripheral side wall and bottom plate. A cover member, which is housed in the main body and formed to cover the top surface and left and right side surfaces of the cabinet main body, is attached to the cabinet main body. A widely used method for fixing the cover member to the cabinet body is to fix the cover member to the cabinet body using a total of four screws, two from each side of the left and right sides of the cover member.

On the other hand, in order to reduce product costs, there is a need to reduce the number of screws even by just one, and to shorten assembly time. In accordance with this requirement, a method has also been proposed in which the lower ends of the left and right sides of the cover member are bent inward and the cover member is fitted into the cabinet body from the rear. According to this method, only the rear end of the cover member is screwed to the cabinet main body, and the two do not come apart, making it possible to reduce the number of screws and reduce costs. However, the work area required for assembly is equal to the depth of the cabinet body, which not only takes up space but also reduces work efficiency.

[Purpose of the invention] The purpose of the invention is to reduce the number of fixing screws and to provide a device cabinet with high assembly efficiency.

[Structure of the invention] This invention is a cabinet for equipment that has a cabinet body having a front wall, a rear wall, left and right side walls, and a bottom plate, and a cover member that covers the top surface of the cabinet body. It is installed almost vertically in the middle part between the rear walls,
The cover member has left and right outer side walls so as to cover the left and right side walls;
The inner surface has a fitting protrusion that protrudes inward to fit into the vertical groove, and the left and right outer side walls at positions where the left and right side walls do not come into contact with the inner surface when the fitting protrusion is fitted into the vertical groove. It is characterized by having a locking protrusion provided on the inner surface.

[Example] An example of this invention shown in the drawings will be described below. FIG. 1 shows a first embodiment of this invention, in which a cabinet main body 1 has four side walls, a front side wall 2, a rear side wall 3, left and right side walls 4, 5, and a bottom plate (on which parts 6 of the equipment are placed). (not shown) are integrally molded from synthetic resin. Approximately midway between the left and right side walls 4, 5 are formed vertical grooves 7, 8 that are substantially perpendicular and open at their outer and upper and lower ends.

Cover member 1 that covers the top surface of the cabinet body 1
1 is a top plate cover part 12 and a left and right side wall cover part 1
3 and 14. Left and right side wall cover part 1
Fitting protrusions 15 and 16 are formed integrally with the left and right side wall cover parts 13 by bending them inward at the lower ends of the left and right side wall cover parts 13 at intervals at the front thereof.
The fitting protrusions 15 and 16 have a length and width sufficient to fit into the vertical grooves 7 and 8. Locking protrusions 17 and 18 are provided at the rear portions of the lower ends of the left and right side wall cover parts 13 and 14 at intervals from the fitting protrusions 15 and 16. The locking protrusions 17 and 18 lock when the fitting protrusions 15 and 16 are fitted into the vertical grooves 7 and 8.
It is provided at a position where the left and right side walls 4, 5 and their inner surfaces do not come into contact.

A rim 19 is integrally provided at the rear end of the cover member 11 so as to come into contact with the rear side wall 3 when assembled, and an insertion opening 20 for a screw 21 passes through the center of the rim 19. A rim 22 that comes into contact with the back surface of the front side wall 2 when assembled is also integrally formed at the front end of the cover member 11.

When attaching the cover member 11 to the cabinet body 1, the fitting protrusions 15 and 16 are first inserted vertically from the upper ends of the vertical grooves 7 and 8. Fitting protrusion 15,1
6 is inserted to the lower end of the vertical grooves 7, 8, the cover member 11 is slid toward the front side wall 2 while bringing the upper surfaces of the fitting protrusions 15, 16 into contact with the lower surface of the bottom plate. At this time, the locking protrusion 17,1
Since the upper surface of 8 is also positioned so as to be able to abut against the lower surface of the bottom plate, the locking protrusions 17 and 18 do not prevent sliding. After the rim 22 is brought into contact with the back surface of the front side wall 2, the screw 21 is inserted through the insertion opening 20 of the rim 19 and screwed to the rear side wall 3.
Since the cover member 11 is fitted into the back surface of the bottom plate by the fitting protrusions 15, 16 and the locking protrusions 17, 18, the cabinet body 1 and the cover member 11 are firmly fixed with one screw 21. be done.

In the second embodiment of this invention shown in FIG. 2, a vertical groove 25 provided at the same position as the vertical grooves 7 and 8 of the first embodiment is closed at its lower end by the left and right side walls 4 and 5. It's taking shape. A horizontal lateral groove 26 is provided in the left and right side walls 4 so as to communicate with the lower end of the vertical groove 25, and the front end of the lateral groove 26 is closed by the front side wall 2, but the rear end is open. Fitting protrusions 27, 28 and locking protrusions 29, 30 are attached to the inner surfaces of the left and right side wall cover parts 13, 14 of the cover member 11 at a distance similar to that of the first embodiment. These protrusions 27...30 are located at higher heights than the first embodiment, and the horizontal grooves 26
It is now possible to mate with the

In this embodiment as well, the method of assembling the cabinet body 1 and the cover member 11 is exactly the same.
The cover member 11 is fixed in the vertical direction by engagement between the lateral groove 26, the fitting protrusions 27 and 28, and the engaging protrusions 29 and 30.

[Effects of the invention] As described above, the device cabinet of this invention has a simple structure and can be assembled extremely easily. Further, when assembling the cover member, it can be assembled if there is a space at the rear that is about 1/3 of the depth of the cover member, so the space required for assembly is also small. Therefore, the cost required for cabinet assembly can be reduced.
