Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

The case structure is suitable for stacking various standard height systems, such as: 44.45mm, 20mm, etc. The structure covers various chassis materials, such as sheet metal, aluminum casting, plastics and the like.

As shown in fig. 1, a standard height scale case comprises a front panel 1, a rear panel 3 and a body 2, wherein the front panel 1 and the rear panel 3 are respectively arranged on the front end surface and the rear end surface of the body 2, the height dimension a of the front panel 1 of the case strictly refers to the standard height dimension, the height dimension B of the body 2 is smaller than the height dimension a of the front panel 1, and height differences are respectively left on the upper side and the lower side, as shown in the enlarged part of fig. 1. The rear panel 3 is designed integrally with the body 2 or may be designed separately. A row of fixing screw holes are reserved on the upper side and the lower side of the two side faces of the machine body 2 respectively and used for adding a support structure to assist in fixing during stacking.

The upper and lower high clearance that the machine case was reserved can guarantee to cooperate the zero clearance between the front panel 1 when stacking, and the clearance between the fuselage 2 is inside can add the supporting structure of certain thickness, is used for interval or lifts, and can guarantee that the height after the stack still accords with standard height requirement.

As shown in fig. 2-4, 3 standard 3U instruments (44.45mmx 3=133.35 mm) can be stacked to have a standard 9U height by the side support members 4 (44.45mmx9=400.05mm), and the longitudinal height of the side support members 4 is set to a value that can match the gap of the chassis and is fixed by the reserved upper and lower side screw holes.

In this embodiment, the side supporting member 4 is a T-shaped bracket formed by three plates facing each other, wherein two plates facing each other up and down are provided with mounting screw holes corresponding to the fixing screw holes of the body, so that the side supporting member 4 and the body 2 are connected by screws. The plates horizontally oriented in the T-shaped support are positioned in the interval of the machine body 2 in the stacking combined structure, and the thickness of the plates can be designed according to the size of the interval to play a certain supporting role.

As shown in fig. 5-6, standard chassis placement in a cabinet via brackets may achieve standard full U placement. The bracket is L-shaped and fixed with a cabinet snap nut, and the standard system case is supported and stacked in the cabinet through the bracket. Fig. 2 and 5 herein illustrate two configurations of such a standard system chassis: the stacking and combining without entering the cabinet can be realized by the side T-shaped support member of figure 2. Parallel stacking within the cabinet may be accomplished by the L-shaped brackets of fig. 5. The two types can be selected alternatively, and the total height can be guaranteed to be the standard system height after being stacked.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, but all equivalent modifications or changes made by those skilled in the art according to the present invention should be included in the protection scope of the claims.
