Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet structure for accommodating electronic communication equipment, and more particularly to a novel cabinet structure which is excellent in rigidity despite its installation floor area being smaller than its height.

[0002]

2. Description of the Related Art Recent electronic communication equipment is housed in a tall cabinet which has a relatively small bottom area in order to save the installation space and accordingly has a high height to secure the entire capacity. It is becoming more frequent. Such a cabinet has been devised in various ways in order to maintain its structural strength.

FIG. 4 shows one of such cabinet structures. According to this, the main body of the cabinet includes the bottom plate 1, the top plate 2, and the pair of left and right side plates 3. The bottom plate 1 and the top plate 2 are bent at their front and rear sides to form tongues 1a and 2a at their four corners, respectively, while the side plate 3 is bent at its four sides and engageable with the tongues 1a and 2a at their four corners. The slit 3a is formed. The tongue pieces 1a, 2a and the slits 3a are engaged with each other so that the bottom plate 1,
The top plate 2 and the side plates 3 are positioned with respect to each other, and fixed to each other by screwing through holes provided in the engagement area.

As described above, since the bottom area of this cabinet is relatively small, a pedestal 20 is separately prepared for the purpose of reinforcing the bottom plate 1 that supports the weight, and is installed under the bottom plate 1 and screwed and fixed. It The door 21 and the back plate (not shown) are attached to the cabinet body thus formed as usual to complete the cabinet.

[0005]

In such a conventional cabinet, the four corners of the bottom plate 1 and the top plate 2 are folded back to form the tongue pieces 1a and 2a, and this portion is used as a joining region with the side plate 3. Therefore, in order to have strength as a structural member, it is necessary to increase the thickness of the material forming the top plate and the bottom plate forming the tongue, and moreover, the side plate corresponding to the tongue is folded back. It is necessary to make the width of the part large enough. However, this has the drawback of increasing the weight of the entire cabinet and increasing the installation area itself.

Furthermore, since a pedestal as another structural material is required, there is also a problem that the manufacturing cost increases.
The present invention solves the above problems of the prior art and uses a relatively thin material and is lightweight,
An object of the present invention is to provide a cabinet structure which has sufficient structural strength and requires a small installation floor area.

[0007]

The object of the present invention is to integrally form a frame member having a U-shaped cross section by left and right side plates and a back plate for connecting them to each other along a pair of bending lines. Welding a reinforcing member extending in the up-down direction, a top plate and a bottom plate having bag bending parts on four sides are arranged above and below the reinforcing member, and the bag bending parts are brought into contact with the upper and lower ends of the reinforcing member. This is achieved by a cabinet structure of electronic communication equipment characterized by welding and fixing.

[0008]

According to the present invention, the bag bending portion is formed on the top plate and the bottom plate which form the cabinet to increase the strength thereof, and the back plate and both side plates are integrally formed by sheet metal working, and It is reinforced by welding the reinforcing plate. Therefore, even if these members are made of a material thinner than the conventional one, sufficient strength is guaranteed, and a lightweight cabinet with a small installation floor area is provided.

Based on the preferred embodiment shown in the drawings,
The present invention will be described in more detail. [Embodiment] FIG. 1 is an exploded perspective view showing an example of a main body structure of an electronic equipment cabinet of the present invention. This main body structure is constructed by integrally welding and fixing a bottom plate 1, a top plate 2, and a pair of left and right side plates 3.

The bottom plate 1 and the top plate 2 have substantially the same structure, and the four sides of the rectangular shape are bent twice at a right angle with a predetermined width to form a bag bending portion A. Left and right side plates 3
Is formed as a frame member 5 having a U-shaped cross section from a single metal sheet together with the back plate 4 by sheet metal working, and the front side thereof is folded back with a predetermined width along the height direction to form the channel portion B. is doing.

On the inner surface of the frame member 5 having this U-shaped cross section,
A reinforcing member 6 having an L-shaped cross section is welded and fixed in the height direction along the bending line between the side plate 3 and the back plate 4 so as to straddle both the plates 3 and 4. The length of this reinforcing member 6 is the frame member 5
A predetermined space corresponding to the height of the bag bending portion of the top plate 2 and the bottom plate 1 is set above and below the space. Furthermore,
The reinforcing member 6 is provided with a plurality of mounting holes 7 at a predetermined pitch so that the shelf 22 having an arbitrary height can be fixed at an arbitrary position.

In order to assemble these members, the top plate 2 and the bottom plate 2 are arranged above and below the frame member 5 and brought into contact with the tip of the reinforcing member 6. As a result, the top plate 2 and the bottom plate 1 are inserted and positioned in the upper and lower ends of the frame member 5. In this state, the frame member 5 and the top plate 2 and the bottom plate 1 are welded and fixed. As a result, the respective members are firmly joined and can have sufficient strength.

A front door, a decorative plate and the like are attached to the basic structure thus constructed as usual to complete a cabinet. As an application example of this cabinet structure, as shown in FIG. 2, a cable holder 8 can be attached using the attachment hole 7 of the reinforcing member 6. That is, the rear end of the cable holder 8 may be screwed into an arbitrary mounting hole 7, and the front end may be fixed to the folded edge of the channel portion B of the side plate 3 by the metal fitting 9.

As another form of the reinforcing member 6, as shown in FIG. 3, a reinforcing plate 11 having a special cross section having lateral holes 10 of relatively coarse pitch and an adjusting plate 12 added thereto are combined. It is also possible. The reinforcing plate 11 is welded and fixed so as to straddle the side plate 3 and the back plate 4 like the above-mentioned reinforcing member 6, and has a function of increasing the strength. on the other hand,
The adjusting plate 12 is provided with a large number of the mounting holes 7 and the holes 1 are formed on the sides thereof at positions corresponding to the elongated holes 10.
It has 3. As a result, the adjustment plate 12 can be moved and positioned in the left-right direction within the range of the elongated hole 10 and finely adjusted with the position of the mounting hole on the shelf side to be mounted.

[0015]

As described above in detail, according to the present invention, the top plate and the bottom plate, which are formed by bending the four sides to form the bag-bent portion, and the frame member formed integrally with the back plate by sheet metal processing are reinforced. Since the cabinet body is constructed by welding and fixing it to what is reinforced with members, it is possible to construct a structure with high structural strength with a thin sheet metal material, and a cabinet with a small weight and a small installation floor area. The structure can be obtained. Further, since the shelf mounting holes are provided in the reinforcing member at a predetermined pitch, it is possible to mount the shelf having an arbitrary height at an arbitrary position.
