Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding room technology, and in particular to a multi-layered electromagnetic shielding room. Background Technology

[0002] Electromagnetic shielding rooms are an important part of the electromagnetic compatibility (EMC) field. An electromagnetic shielding room is essentially a steel-plate house, with cold-rolled steel plates as its main shielding material. It includes a six-sided shell, doors, windows, and other typical building elements, but requires extremely tight electromagnetic sealing performance. All incoming and outgoing pipelines are also shielded to block electromagnetic radiation from entering or leaving the room. The main function of an electromagnetic shielding room is to isolate external electromagnetic interference, ensuring the normal operation of indoor electronic and electrical equipment. Especially in the measurement and testing of electronic components and electrical equipment, electromagnetic shielding rooms (or anechoic chambers) are used to simulate an ideal electromagnetic environment, improving the accuracy of test results, blocking the spread of indoor electromagnetic radiation to the outside, and shielding and isolating strong electromagnetic radiation sources to prevent interference with the normal operation of other electronic and electrical equipment or even harm to the health of personnel, prevent information leakage from electronic communication equipment, and ensure information security.

[0003] In the use of shielded doors, it is necessary to frequently open and close the shielded doors for staff to enter and exit. During this process, the entrances and exits are open, and indoor electronic and electrical equipment is prone to radiation leakage or external electromagnetic interference. Therefore, this utility model proposes a multi-layered electromagnetic shielding room to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a multi-layered electromagnetic shielding room. When the shielding door is opened, the frame moves to the left end, and the extension rod and shielding curtain move to the entrance and exit. The shielding curtain blocks the entrance and exit, providing a certain degree of shielding without affecting the entry and exit of personnel, thereby increasing the overall shielding effect.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a multi-layered electromagnetic shielding chamber, including a chamber body and a shielding door, an inlet and outlet are provided on one side of the chamber body, and guide rails are provided at the upper and lower ends of the inlet and outlet. A frame is movably provided between the two sets of guide rails, and hinge arms are hinged at the four corners of the frame. Hinge ears are provided at the four corners of the inner side of the shielding door. The four sets of hinge arms are respectively hinged to the four sets of hinge ears. A guide component is provided at the lower left end of one side of the chamber body, and the guide component is used to guide the hinge arm at the lower left end.

[0006] The shielding door is adapted to the entrance and exit. An extension rod is provided above the right end of the frame, and a shielding curtain adapted to the entrance and exit is provided below the extension rod.

[0007] A further improvement is that the guide component is a guide rail, and the guide rail is provided with a straight groove and an inclined groove. The inclined groove is located at the right end of the straight groove, and the straight groove and the inclined groove are connected. One end of the bottom of the hinge arm at the lower left end is provided with a guide wheel, and the guide wheel is adapted to the straight groove and the inclined groove.

[0008] A further improvement is that: both sides of the upper and lower ends of the frame are provided with drive wheels, and the drive wheels are driven to rotate by a motor, and the drive wheels are adapted to the guide rail.

[0009] A further improvement is that the shielding curtain is provided in multiple sets, and the coverage area of ​​the multiple sets of shielding curtains is greater than the area of ​​the inlet and outlet.

[0010] A further improvement is that the sidewall of the chamber includes a protective layer, a support layer, and an aluminum plate shielding layer, with the support layer located inside the protective layer and the aluminum plate shielding layer located inside the support layer.

[0011] A further improvement is that the bottom of the chamber is provided with a support plate, and the support plate is provided with fixing holes. The support plate is fixed to the ground through the fixing holes and bolts.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1.
