Description

Technical Field

[0001] This invention relates to the field of shielding cabinet technology, specifically to a shielding cabinet that can meet the requirements of harsh environments. Background Technology

[0002] A shielded cabinet is a type of cabinet, also known as an electromagnetic shielding cabinet. Shielded cabinets can be used to house computers and can prevent electromagnetic waves from harming people. They are electromagnetic shielding devices that can effectively suppress the leakage of electromagnetic information from computers and prevent external strong electromagnetic interference from affecting the normal operation of computers.

[0003] For example, the Chinese authorized patent (Intelligent Electric Shielding Cabinet) with announcement number CN205030046U includes a cabinet body with a door, a motor at the top, a power filter, an automatic shielding effectiveness detector, a signal filter, and a controller at the top of the cabinet. The door has a control panel, and the cabinet interior contains a temperature and humidity detector. In use, the door is controlled by a motor, making it convenient to operate. The automatic shielding effectiveness detector installed inside the cabinet can detect the shielding effect and also monitor the temperature and humidity inside, displaying this information on the control panel for reminders, thus meeting usage requirements.

[0004] However, most existing shielded cabinets rely on cable management boards for cable management, which cannot be adjusted in angle, making cable management inconvenient. Therefore, they do not meet the current needs. In response, we have proposed a shielded cabinet that can meet the requirements of harsh environments. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention involves setting up a cable management sliding frame inside the shielded cabinet, with several cable management seats inside the frame. Each cable management seat mainly consists of a first flexible sheet, a second flexible sheet, a connecting seat, ball bearings, a bearing sleeve, and a cross-shaped movable plate. The cable is pressed into the first flexible sheet through the first opening. Due to the elasticity of the first flexible sheet, the first opening can expand. After the cable is inserted, the first opening returns to its original size to prevent the cable from falling out. Then, the cable is squeezed through the second opening into the second flexible sheet. The second flexible sheet operates on the same principle as the first flexible sheet, only differing in size. One second flexible sheet holds one cable, and one first flexible sheet holds seven second flexible sheets, meaning seven cables can be secured. The connecting seat is rotatably connected to the bearing sleeve via ball bearings, allowing the cable management seat to rotate and adjust the angle of the first flexible sheet. Compared to existing non-adjustable cable management boards, this invention is suitable for cables at different angles, preventing bending and damage to the cables. It also allows for neat arrangement of cables, facilitating quick troubleshooting and maintenance later.

[0023] 2. The cross-shaped moving plate at the upper end of the bearing sleeve moves along the cross-shaped moving groove on the inner wall of the cable management sliding frame. The cross-shaped moving groove on the inner wall of the sliding frame surrounds the entire cable management sliding frame, which facilitates the adjustment of the position of the cable management seat and improves flexibility.

[0024] 3. By setting a ventilation opening on one side of the shielding cabinet and installing a side panel on the same side as the ventilation opening, the side panel is fixed to the shielding cabinet by connecting bolts to the external side panel, thus sealing the ventilation opening. At the same time, an outdoor unit storage frame is set below the side panel. During normal use, the ventilation opening is sealed and protected by the side panel. When an external cooling device is required, the side panel is removed and the outdoor unit of the cooling device is installed inside the outdoor unit storage frame, which provides support.
