[0036] The outer skin is wrapped around the outside of the frame 7, and the door panel is installed in front of the frame 7 through a hinge; the cover panel 6 is installed on the side and back of the frame 7, thereby forming a cabinet.

[0037] To facilitate the transportation of the cabinet, a lifting ring 2 is provided on the top of the cabinet; in order to improve the cabinet's anti-vibration and impact performance, shock absorbers 5 are provided on the bottom and back of the cabinet.

[0038] In the above scheme, specifically:

[0039] The top frame 7.1 and the bottom frame 7.2 are welded together by square tubes, and the columns 7.7 are welded together by bending two thin plates. To make the cabinet more load-bearing while being lighter, the square tubes used in the top frame 7.1 and the columns 7.7 have a square cross-section, while the square tubes used in the bottom frame 7.2 have a rectangular cross-section, with a slightly larger cross-sectional area and wall thickness than square tubes.

[0040] The outer skin 1 is formed by bending a thin plate and is wrapped around the cabinet surface by welding. In order to enhance the overall waterproofness of the cabinet, the outer skin 1 wrapped around the front of the cabinet is provided with skin flanges 1.1 extending to all sides.

[0041] See attached Figure 7 、 8 The door panel is a split structure consisting of an upper door panel 3 and a lower door panel 4. In order to ensure the electromagnetic compatibility of the cabinet, the door panel is provided with a door panel sealing groove 4.1, and a conductive shielding strip 9 is provided in the door panel sealing groove 4.1. When the door panel is closed, the conductive shielding strip 9 contacts and fits tightly with the corresponding skin flange 1.1, so that the cabinet forms a continuous conductor.

[0042] The installation column 7.4 and the front column 7.7 are provided with a longitudinally arranged wiring board 7.3, which not only improves the strength of the cabinet but also facilitates the arrangement of cables inside the cabinet.

[0043] On the basis of the above scheme, further:

[0044] In order to improve the strength of the frame, trapezoidal reinforcing ribs 7.6 are provided at the connection positions between the top frame 7.1 and the columns 7.7, and between the bottom frame 7.2 and the columns 7.7.

The outer skin 1 is a 1.5mm thick steel plate which is bent and welded. The door plate is welded with the door plate sealing groove 4.1, and the conductive shielding strip 9 is installed in the door plate sealing groove 4.1. When the door plate is closed, the conductive shielding strip 9 contacts and closely cooperates with the corresponding outer skin flange 1.1, so that the whole cabinet forms a continuous conductive body, and the electromagnetic shielding effect is improved.

[0052] The top frame 7.1 is a square frame structure which is welded by 40mm*40mm*2mm square tubes. Since the bottom frame is the load-bearing core of the whole structure, the bottom frame 7.2 is a square frame structure which is welded by 60mm*40mm*3mm rectangular tubes. The triangular reinforcing ribs 7.9 are welded at the four corners of the top frame 7.1 and the bottom frame 7.2, so as to improve the structural strength at the lifting ring 2 and the damper 5.

[0053] The mounting column 7.4 is welded together through two 3mm bending pieces, forming a rectangular tube structure with a flange, and the formed flange is used to install and fix the subrack in the cabinet. A plurality of wiring boards 7.3 are welded from top to bottom between the front column 7.7 and the mounting column 7.4, and the wiring boards 7.3 are provided with holes for cable binding. At the same time, the wiring boards 7.3 can also improve the structural strength between the columns 7.7. The trapezoidal reinforcing ribs 7.6 are welded at the connecting positions of the mounting column 7.4 and the top frame 7.1 and the bottom frame 7.2, so as to improve the structural strength of the connecting positions and reduce stress concentration. The cross beams 7.5 are respectively welded between the front column 7.7 and the rear column 7.7, and the cross beams 7.5 are cut from 40mm*40mm*2mm square tubes. The U-shaped channel steel 7.11 is welded at the mounting position of the rear damper 5 between the rear columns, and the elbow plate 7.12 is welded in the channel steel, so as to improve the structural strength of the mounting position of the rear damper.

[0054] The guide rail 8 is installed between the mounting column 7.4 and the rear column 7.7 through bolts. The lifting ring 2 is installed on the triangular reinforcing rib of the top frame 7.1.
