Abstract

(57) [Summary] [Purpose] A housing structure that can be easily mounted on a rack without damaging the subrack bottom plate. [Structure] A round hole 3 is formed on one side surface of a support column of a rack 1, and an elliptical hole 4 is formed on a side surface of the other support column. This round hole 3
Two round bars 4 are passed between the and the elliptical hole 4. When mounting the subrack 6 on the rack 1, the subrack 6 is first placed on the round bar 5, the subrack 6 is pushed and slid backward, and the subrack is fixed to the front edge of the column of the rack 1 with the screw 7.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a housing structure, and more particularly to a housing structure in which a subrack is mounted on a rack such as a 19-inch rack used for communication devices.

[0002]

[Prior Art]

 Conventionally, this type of housing structure is the structure shown in FIG. FIG. 2 is a perspective view showing the structure of a conventional example. L-shaped metal fittings 8 are fixed to the side surfaces of the columns on both sides of the rack 10 with screws 9. When mounting the subrack 6 on the rack 10, the subrack 6 is first placed on the L-shaped metal fitting 8, the subrack 6 is pushed and slid backward, and fixed to the front edge of the column of the rack 10 with the screw 7. The subrack 6 contains a plurality of units inside and is heavy in weight. Therefore, such a temporary holding structure by the L-shaped metal fitting 8 is required.

[0003]

[Problems to be solved by the device]

 In this way, in the conventional example, since the L-shaped metal fitting is used for the holding structure, when sliding the subrack backward, a force is required because the frictional resistance between the L-shaped metal fitting and the subrack bottom plate is large. Moreover, there is a problem that the subrack bottom plate is scratched.

[0004]

[Means for Solving the Problems]

 The housing structure of the present invention includes a rack, a plurality of subracks mounted on the rack, and a support structure for temporarily supporting the subracks when mounting the subracks provided on the rack side. In the structure, the support structure is a structure in which a round bar is provided between a round hole formed in one side surface of a column of the rack and an elliptical hole formed in the other side surface of the column.

[0005]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the structure of this embodiment. A round hole 3 is formed on one side surface of the rack 1 and an elliptical hole 4 is formed on the other side surface of the rack. Two round bars 4 are provided between the round hole 3 and the elliptical hole 4. When mounting the subrack 6 on the rack 1, first place the subrack 6 on the round bar 5, push the subrack 6 and slide it backward, and fix the subrack 6 to the front edge of the rack 1 with the screw 7. To do. When the round bar 5 is attached to the rack 1, one end of the round bar 5 is first inserted into the round hole and then the other end is dropped into the elliptical hole.

[0006]

[Effect of the device]

 As described above, since the present invention uses the round bar for the holding structure, when the subrack is slid backward, the rolling force of the round bar rolls and the friction resistance between the subrack and the bottom plate is reduced, so that the pushing force is reduced. It is small and has the effect of not damaging the subrack bottom plate. Furthermore, since the screw is not used for mounting the round bar, there is an effect that the mounting becomes easy.

Claims (1)

[Scope of utility model registration request] 1. A housing structure comprising: a rack; a plurality of subracks mounted on the rack; and a support structure for temporarily supporting the subracks provided on the rack side when the subracks are mounted. The housing structure is characterized in that a round bar is provided between a round hole formed in one side of a column of the rack and an elliptical hole formed in the other side of the column opposite to the rack.
