[0002] As people's awareness of the hazards of electromagnetic leakage emissions in confidential information systems has gradually deepened, various means of preventing electromagnetic leakage emissions have begun to be widely used when building confidential information networks, such as building electronic shielding cabinets. Electronic shielding cabinets are widely used due to their small size, easy installation and flexible use.

[0003] In the existing electronic shielding cabinets, the electronic shielding cabinets are generally high in height and heavy in weight. When the user finishes using the electronic shielding cabinet, the user needs to push the electronic shielding cabinet to move or carry it as a whole, which is inconvenient to carry.

Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0026] Example 1: Reference Figure 1-3A portable foldable electronic shielding cabinet comprises a base 1, a universal wheel 2 is arranged at the bottom of the base 1, a fixing plate 1 3 and a fixing plate 2 4 are arranged at the top of the base 1, a motor is arranged on one side of the inner wall of the fixing plate 1 3, a motor shaft 1 is arranged at the output end of the motor, a rotating disk 301 is arranged at one end of the motor shaft 1, a movable shaft 309 is arranged just above the rotating disk 301, a rotating ring 303 is arranged on the outer surface of the movable shaft 309, a plurality of support shafts 302 distributed at equal intervals are arranged between the rotating disk 301 and the fixing plate 2 4, a plurality of support frames 304 are symmetrically arranged on both sides of the support shaft 302, and every two of the support frames 304 are connected by a connecting shaft 305, located The lowest support shaft 302 is fixedly connected to one side of the outer wall of the fixed plate 2 4, and a slide groove 401 is provided on the side of the fixed plate 2 4 close to the rotating disk 301, and a slider 402 is movably connected in the slide groove 401, and the movable shaft 309 passes through the two support frames 304 and is fixedly connected to the slider 402, and a support column 306 is provided above the support frame 304 located at the top, and a telescopic rod 307 is provided on the top of the fixed plate 2 4, and a support plate 308 is provided above the support column 306 and the telescopic rod 307, and the top of the support plate 308 is fixedly connected to the cabinet 5, and a recessed block is provided on one side of the outer wall of the rotating disk 301, and the rotating ring 303 is movably connected in the recessed block.

[0027] When the electronic shielding cabinet needs to be moved after use, the motor is started first. The motor starts to drive the motor shaft 1 and the rotating disk 301 to rotate. When the rotating disk 301 rotates, the rotating ring 303 is driven to rotate along the rotation trajectory of the rotating disk 301. When the bottom recessed block of the rotating disk 301 rotates to the top, the rotating ring 303 falls into the recessed block, and then the rotating ring 303 drives the slider 402 to slide down to the bottom of the slide groove 401. During the falling process of the rotating ring 303, several support frames 304 are contracted and folded together, and the telescopic rod 307 is also contracted downward. When the support frame 304 contracts downward, it drives the support column 306 to descend, so that the support column 306 and the telescopic rod 307 descend and drive the support plate 308 to descend. The descending of the support plate 308 drives the cabinet 5 to descend. When the cabinet 5 descends to the lowest end, the overall volume of the electronic shielding cabinet is reduced, which is beneficial for the staff to carry the electronic shielding cabinet.

[0028] Example 2: Reference Figure 4-6On the basis of the first embodiment, a technical solution of a portable foldable electronic shielding cabinet is provided, wherein a cabinet door 6 is provided on one side of the cabinet 5, and a display screen 7, a function button 8 and a switch handle are provided on one side of the outer wall of the cabinet door 6, an optical fiber conduit 503 is provided on the inner bottom of the cabinet 5, and a network waveguide 504 is provided on one side of the inner wall of the cabinet 5, a layer plate 501 is fixedly connected to the inner center of the cabinet 5, a PDU power supply 502 is provided above the layer plate 501, a heat dissipation component is provided on the top of the cabinet 5, and the heat dissipation component includes a heat dissipation port 9 located at the top of the cabinet 5, the heat dissipation port 9 is communicated with the interior of the cabinet 5, a fixing frame 901 is fixedly connected to the inner bottom of the heat dissipation port 9, and the inner center of the fixing frame 901 is fixedly connected to the fixing frame 901. An axial flow fan is provided at the center, and a motor shaft 902 is provided at the output end of the axial flow fan. A heat dissipation blade 903 is provided on the outer surface of the motor shaft 902. A heat dissipation frame 10 is provided on the inner top of the heat dissipation port 9. A sealing strip is provided on the side of the cabinet door 6 close to the outer wall of the cabinet 5. A sealing groove matching the sealing strip is opened on one side of the outer wall of the cabinet 5. The outer surface of the function button 8 is covered with a transparent acrylic plate, and the surface of the handle is covered with an anti-slip protective cover. A controller is provided in the inner wall of the base 1, and a control switch is provided on one side of the outer wall of the cabinet 5. The control switch, the motor, the axial flow fan, the PDU power supply 502, the optical fiber conduit 503, and the network waveguide 504 are all electrically connected to the controller.

[0029] In this embodiment, when the electronic shielding cabinet needs to be used, the sealing strip on the cabinet door 6 is embedded into the sealing groove to complete the sealing work of the electronic shielding cabinet. When the electronic shielding cabinet is in operation, the shielding effect of the electronic shielding cabinet is increased by the optical fiber duct 503 and the network waveguide tube 504. The interior of the cabinet 5 can be detected and measured and controlled through the display screen 7 and the function button 8. When the electronic shielding cabinet generates heat during operation, the axial flow fan is started, and the movement of the axial flow fan drives the motor shaft 902 to rotate. The rotation of the motor shaft 902 drives the heat dissipation blades 903 to rotate. The operation of the heat dissipation blades 903 drives the heat inside the cabinet 5 to be finally discharged from the heat dissipation frame 10.

[0030] In actual application, when using the electronic shielding cabinet, first embed the sealing strip on the cabinet door 6 into the sealing groove, thereby completing the sealing work of the electronic shielding cabinet. When the electronic shielding cabinet generates heat during operation, the axial flow fan is started at this time, and the movement of the axial flow fan drives the motor shaft 2 902 to rotate. The rotation of the motor shaft 2 902 drives the heat dissipation blades 903 to rotate. The operation of the heat dissipation blades 903 drives the heat inside the cabinet 5 to be finally discharged from the heat dissipation frame 10. When the electronic shielding cabinet is used up, first start the motor. The motor starts to drive the motor shaft 1 and the rotating disk 301 to rotate. When the rotating disk 301 rotates, it drives the rotating ring 303 along the rotation trajectory of the rotating disk 301. Rotate, when the bottom recessed block of the rotating disk 301 rotates to the upper side, the rotating ring 303 falls into the recessed block, and then the rotating ring 303 drives the slider 402 to slide down to the bottom of the slide groove 401. In the process of the rotating ring 303 falling, several support frames 304 shrink downward and fold together, and the telescopic rod 307 also shrinks downward. While the support frame 304 shrinks downward, it drives the support column 306 to descend, so that the support column 306 and the telescopic rod 307 descend and drive the support plate 308 to descend, and the support plate 308 descends and drives the cabinet 5 to descend. When the cabinet 5 descends to the lowest end, the overall volume of the electronic shielding cabinet is reduced, which is beneficial for the staff to carry the electronic shielding cabinet.
