In addition, vertical and horizontal frames or partitions can be added appropriately depending on the size of the frame or the equipment stored inside, but since they are not the main part of this application, illustrations and detailed descriptions are omitted. The characteristic part of the present invention lies in the characteristics of the joints between the bottom plate 2 and the top plate 3 and the left and right side panels 4, 5, so this part will be described in detail below.

FIG. 1 is a partial perspective view showing the left rear lower corner of FIG. 3 , and the exploded perspective view of FIG. 1 is FIG. 2 . In addition, the shape of the corner fittings 6 is basically the same at the four corners on the bottom plate 2 side and the four corners on the top plate 3 side. However, it is formed into a symmetrical shape front-back, left-right, and up-down. Next, the lower left corner will be described as a representative. In order to avoid complexity, all the corner fittings at each corner will be indicated with the same symbols.

The structure of the corner portion will be described with reference to FIGS. 1 and 2 .

Both sides in the width direction of the bottom plate 2 are bent in an L-shape in the vertical direction to form a bent portion 2a, and both sides in the depth direction are similarly bent in the vertical direction to form a bent portion 2b.

In the following description, the horizontal portion of the bottom plate 2 that does not include the bent portions 2a, 2b is referred to as a bottom surface. The left and right bent portions 2a are formed in advance to be longer than the width of the bottom surface in the depth direction, and the extended ends are bent parallel to the bent portion 2b to form an end bent portion 2c. A gap is formed between the bent portion 2b and the end bent portion 2c because the bent portion 4a of the left side panel 4 to be described next is fitted.

The left side panel 4 bends both sides in the vertical direction in a U-shape to form a bent portion 4a.

The corner fitting 6 has a joint surface 6 a joined to the bent portion 4 a of the left side panel 4 , a joint surface 6 b joined to the bent portion 2 b of the bottom plate 2 , and a joint surface 6 c joined to the bottom surface of the bottom plate 2 . The joining surfaces 6a, 6b, and 6c are formed at right angles to each other.

In addition, the joint surface referred to here is not only a "surface" which contacts a joint object, but also includes members forming a part of the contact surface. That is, the corner fitting 6 is constituted by a joint surface 6a, a joint surface 6b, and a joint surface 6c.

The bottom plate 2, the left side panel 4 and the corner fittings 6 are joined by rivets. Therefore, rivet holes 7 for joining with the left side panel 4 and rivet holes 8 for joining with the corner fittings 6 are provided on the side of the bottom plate 2 , and rivet holes 9 for joining with the bottom plate 2 and corner fittings 6 are provided on the left side panel 4 . The corner fitting 6 is provided with a rivet hole 11 for joining the bottom plate 2 and a rivet hole 12 for joining the left side panel 4 .

In addition, an attachment hole 13 for foundation fixing is provided on the joint surface 6 c side of the corner fitting 6 , and a foundation hole 14 is provided on the bottom surface of the base plate 2 corresponding to the attachment hole 13 .

The corner fitting 6 is produced by bending a steel plate, a stainless steel plate, an aluminum plate, or the like.

FIG. 4 is a developed view showing one example of the corner fitting 6 before bending.

Rivet holes 11, 12 and mounting holes 13 are formed after the profile is cut from the sheet material as shown. The dotted line in the figure represents the bending line, and the corner fitting 6 as shown in FIG. 1 or FIG. 2 is formed by bending into a right angle at the bending line. At this time, two mounting holes 13 are formed in an overlapping manner. Since the joint surface 6c serving as the base fixing portion is two layers formed by overlapping two surfaces, the bending line in the horizontal direction shown in FIG.

In addition, the corner fitting 6 may be produced by casting metal such as iron or aluminum instead of bending. Casting can freely set the thickness of the plate, and in the case of mass production, it is easier to manufacture.

Next, an assembly method will be described with reference to FIG. 2 .

First, the left side panel 4 and the right side panel 5 are aligned from the outside of the right and left bent portions 2a in the width direction of the bottom plate 2, and the rivet holes 7 and 9 are aligned and joined with rivets. Next, align the three surfaces of the corner fitting 6 with the bent portion 4 a of the left side panel 4 , the bent portion 2 b of the bottom plate 2 , and the bottom surface of the bottom plate 2 . Then, the rivet hole 8 and the rivet hole 11 and the rivet hole 10 and the rivet hole 12 are aligned and joined with rivets. The remaining three corners are also assembled in the same way. At this time, the mounting holes 13 of the corner fittings 6 are formed to match the foundation holes 14 of the bottom plate 2 .

Fig. 5 is a cross-sectional view showing a base fixing portion in Fig. 1 . As shown in FIG. 5 , foundation bolts 15 are embedded in the foundation surface in advance. Therefore, at the foundation bolts 15, the foundation holes 14 and the installation holes 13 of the disk device frame 1 are aligned and fixed with nuts 16. .

As shown in the figure, the plate thickness of the fixing portion of the foundation bolt 15 is two layers at the joint surface 6c of the corner fitting 6 and three layers including the bottom surface of the base plate 2 . Therefore, the rigidity of the foundation fixing part can be improved.

Next, the top side will be described.

Fig. 6 is a perspective view of the front upper left corner of the top of Fig. 1 viewed from the front. The top side is also substantially the same as the bottom side. The top plate 3 has a bent portion formed around it similarly to the bottom plate 2, and therefore, the left side panel 4 is assembled from the outside of the bent portion and joined with rivets. Next, the left side panel 4 and the top panel 3 are joined by rivets using the corner fittings 6 . The remaining three corners are also assembled in the same way. In addition, the horizontal surface other than the bent part of the top plate 3 is also called a top surface.

In the case of using the corner fitting 6 on the top side, the mounting hole 13 of the corner fitting 6 illustrated in FIG. 2 is formed as a mounting hole for hanging the fitting. Therefore, a hole 17 for hanging a fitting is provided on the top surface of the top plate 3 facing the attachment hole 13 . By fastening eyebolts (not shown) or the like with nuts or the like to the holes 17 for hanging fittings, the disk device housing 1 is made to be in a suspendable state.

In the part where the eyebolts are installed, the plate of the corner fitting 6 is formed in two layers, and the top surface of the top plate 3 is combined to form a total of three layers. The rigidity and strength are high and the normal shape of the frame can be maintained.

In addition, the mounting hole 13 of the corner fitting 6 used on the top side does not need to be an oval hole, but may be a round hole. In addition, the mounting holes 13 of the corner fittings 6 used on the bottom side are not limited to oval holes, and may be circular holes.

If the assembly is completed, the state shown in Figure 3 will be formed.

As described above, between the three faces of the left side panel 4, the right side panel 5 and the bottom panel 2 and between the three faces of the left side panel 4, the right side panel 5 and the top panel 3 are riveted by using the corner fittings 6 , forming a frame body of a frame structure with high rigidity in the three directions of up and down, left and right, and front and rear, and a frame body with high rigidity of the base fixing part and the top hanging part can be obtained.

That is, any one of the joint surfaces 6a, 6b, 6c of the corner fitting 6 and the joint surfaces between the side panels 4, 5, the bottom plate 2, and the top plate 3 is connected to the other two surfaces in the shearing direction of the rivet. , and load-bearing in the direction of tension and compression are firmly connected, so not only can the misalignment of the rivet portion be prevented, but also the rigidity of the corner fitting 6 can be effectively utilized to form rigidity in the three directions of front and rear, left and right, and up and down. The frame body of the large frame structure.

In addition, by increasing the strength of the base fixing portion, wobble vibration can be reduced, and thus a housing for a disk device with high vibration resistance can be obtained.

In addition, high processing accuracy is not required for the production of parts, and can be produced by simple bending, and assembly can be done by riveting without welding or other skills, and it is possible to obtain a disk device frame with good manufacturability and low cost. Body 1.

In addition, in the above description, the bottom plate 2, the top plate 3, the left side panel 4, and the right side panel 5 are all joined by the corner fittings 6, but it is also possible to connect the bottom plate 2, the left side panel 4, and the right side in addition to the top plate 3 side. The joints of the panels 5 are joined using corner fittings 6 . In this case, it is possible to obtain a housing for a disk device with a higher rigidity of the base fixing portion with a simpler structure.

As described above, according to the disk device housing of Embodiment 1, the left and right side panels, the bottom plate, and the top plate are combined to form a rectangular parallelepiped, and corner fittings are attached to the inner corners to join the side panels and the bottom plate. The corner fittings have a plurality of joint surfaces intersecting each other at right angles. The joint surfaces of the corner fittings and the bottom surface of the base plate are formed to be thicker than the other joint surfaces, and are provided with mounting holes for foundation fixing. Therefore, simple shapes can be used. The corner fittings constitute a highly rigid frame structure at the corners of the bottom side, and furthermore, a highly rigid chassis for a disk device can be obtained at the base fixing portion.

Therefore, the response magnification when vibration during transportation or vibration caused by an earthquake can be reduced, for example, in the case of storing electrical equipment inside, the acceleration applied to the electrical equipment can be reduced, so it is possible to provide low-cost Frames for switchboards or switchgear with high vibration resistance.

In addition, on the basis of the above, the side panel and the top panel are joined after the corner fittings are attached to the inner corners, and the thickness of the joint surface of the corner fitting joined to the top surface of the top panel is formed thicker than the other joint surfaces, so that the roof can be improved. The rigidity of the side corners maintains the normal shape of the frame even if an external force is applied when the frame is hung, since this portion has high rigidity and strength.

In addition, the corner fittings are made of metal plates by bending them, and the joint surface that makes the plate thicker is two of the bending surfaces formed by bending three parts of the metal plate at right angles to each other. Since the surfaces are stacked in two layers, the corner fittings for joining the corners of the frame can be manufactured at low cost without requiring high machining accuracy.

In addition, since the corner fittings are cast from iron or aluminum metal, the plate thickness can be freely selected, and in addition, it becomes easy to manufacture in the case of mass production.

Implementation mode two

FIG. 7 is an exploded perspective view showing the corner portion on the back side of the bottom plate 2 of the disk device housing according to the second embodiment. Except for the shape of the corner fittings, they are the same as those in Fig. 1 and Fig. 2 of the first embodiment, so the same parts are denoted by the same reference numerals and their descriptions are omitted, and the following description will focus on the differences.

The corner fitting 18 of the present embodiment is formed by integrally connecting the left and right corner fittings of the first embodiment. That is, among the joint surfaces of the corner fitting 6 according to the first embodiment, the joint surfaces extending in the width direction of the frame (in the case of the corner fitting 6 , the joint surfaces 6 b and 6 c ) are extended in the width direction, and formed from the width A corner fitting 18 that extends continuously from the corner at one end of the direction to the corner at the other end.

Referring to FIG. 7 , in the corner fitting 18 of the present embodiment, the joint surface 18 a facing the bent portion 4 a of the left side panel 4 and the bent portion 5 a of the right side panel 5 and the joint surface 6 a of the corner fitting 6 Similarly, the joint surface 18b facing the bent portion 2b of the bottom plate 2 and the joint surface 18c facing the bottom surface of the bottom plate 2 are formed integrally with the left and right joint surfaces 18a across the entire length in the frame width direction.

The bent portion 2b of 2 is aligned with the bottom surface and fixed with rivets.

Similarly, the front side of the bottom plate 2 and the corners of the front side and the back side of the top plate 3 are assembled.

In addition, the corner fitting 6 of the first embodiment may also be used on the top plate 3 side.

As described above, by using one corner fitting 18 for both left and right corners, the number of parts can be reduced, and the number of assembly steps can be reduced.

In addition, since the part where the corner fittings 18 are provided is thickened across the entire length of the frame in the width direction, the rigidity and strength of the frame in the width direction of the bottom plate 2 are greater than those of Embodiment 1, and therefore, a large rigidity can be provided. frame for the disk device. Therefore, for example, when the disk device housing 1 is mounted on site, deformation of the bottom of the housing can be prevented even if a force is applied to the widthwise central portion of the bottom plate 2 by using a lever or the like.

As described above, according to the disk device housing of Embodiment 2, the corner fittings that join the side parts and the bottom plate make the joint surfaces extending in the width direction of the disk device housing out of the joint surfaces constituting the corner fittings be aligned in the width direction. Since it is extended and formed as a corner fitting extending continuously from the corner at one end in the width direction to the corner at the other end, the number of parts and the number of assemblies can be reduced.

In addition, the rigidity and strength of the frame in the width direction of the bottom plate can be improved.

Implementation Mode Three

8 is a perspective view showing a corner portion of the bottom of the disk drive housing according to Embodiment 3, and FIG. 9 is a cross-sectional view showing the base fixing portion of FIG. 8 . Since it is a part corresponding to FIG. 2 of Embodiment 1, the same part is attached|subjected with the same code|symbol and description is abbreviate|omitted, and it demonstrates centering on a difference.

When the disk device housing 1 is used as, for example, a housing of a switch device, an external cable may be drawn in from the outside in order to transmit and receive power to and from an internal main circuit device. This embodiment can cope with the above-mentioned situation.

As shown in FIG. 8 , the point that the corner fittings 19 are separated at each corner is the same as the first embodiment, and the difference is that the joint surface 19c on the side of the base fixing part is extended toward the center side in the depth direction of the frame, and at the extended part A cable hole 20 for passing through external cables is provided.

On the bottom plate 2 side, an opening hole 21 of the same size is also provided at a position corresponding to the cable hole 20 .

In addition, there is a hole cover 22 larger than the outer shape of the cable hole 20 to block the cable hole 20 . In addition, in order to fix the hole cover 22, a fixing hole 23 is formed on the hole cover 22 and a threaded hole 24 is formed on the corner fitting 19. In addition, on the bottom surface of the bottom plate 2, a ratio is formed at a position corresponding to the threaded hole 24. The threaded hole 24 is a relief hole 25 having a large diameter.

The method of fixing using the corner fittings 19 is substantially the same as that of Embodiment 1, so detailed description will be omitted, and differences will be described below.

After assembling the corner fittings 19, when carrying out the operation of introducing the external cables into the frame, make the external cables pass through the opening hole 21 and the cable hole 20, and process the penetration for the cables at the hole cover 22 according to the size and number of the external cables.

Under normal circumstances, the bottom plate 2 is not too thick. If it is desired to directly fix the cover plate 22 on the base plate 2 by screw fastening, then when the plate thickness of the base plate 2 is thin, the fixing screws 26 will penetrate the base plate 2, and the head of the screw is exposed from the base plate 2 of the frame. , There is a danger of scratching the bottom surface of the electrical chamber or floating the bottom plate 2 when the disk device is installed. As a countermeasure, it can be considered to weld a spacer at the bottom plate 2 to prevent screw penetration, or to bend the steel plate part of the fixed cover plate 22 to make the fixed part float, but these measures have a large number of parts. The problem of increasing or increasing the production cost.

For this, in this embodiment, as shown in FIG. 9 , a threaded hole 24 for assembling the hole cover 22 is provided on the corner fitting 19 , and an avoidance hole is provided at the position of the bottom plate 2 corresponding to the threaded hole 24 25. Therefore, when fixing the hole cover 22 with the fixing screw 26, the fixing screw 26 can be prevented from protruding toward the base surface.

As described above, in this embodiment, the joint surface 19c of the corner fitting 19 is extended toward the center side in the depth direction of the frame, and this part is used as the inlet for the external cable, so it has the function of increasing the rigidity of the frame. It also has the function of preventing the fixing screw 26 for fixing the cover hole 22 from protruding toward the bottom, and has the effect of reducing the number of parts and suppressing the manufacturing cost.

In addition, in the above description, the fixing of the corner fittings to the frame has been described by using rivets in consideration of manufacturability, but other than that, the corner fittings can also be fastened with screws or welded. fixed to the frame. In this case, manufacturability deteriorates, but a frame with a more rigid frame structure can be obtained.
