Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding, in particular to an electromagnetic shielding room which is easy to assemble and replace. Background Art

[0002] Electromagnetic shielding room is a shielding body made of conductive or magnetic materials in various shapes. It is mainly used to limit electromagnetic capabilities within a certain space range to suppress radiation interference. It generally provides an interference-free test environment for wireless communication equipment or high-precision equipment. Electromagnetic shielding room has four categories: steel plate assembly type, steel plate welding type, steel plate direct paste type and copper mesh type. Usually, steel plate assembly type and steel plate welding type are used. Among them, steel plate welding type shielding room is generally made of 2-3mm cold-rolled steel plate and keel frame welding. It has high shielding efficiency and can adapt to various specifications and sizes. It is the main form of electromagnetic shielding room, but it is not easy to disassemble and relocate. The assembled electromagnetic shielding room is assembled from steel plate modules with a thickness of 1.5 mm. The production and installation process is relatively simple and it is suitable for projects with small areas and general shielding efficiency requirements. For example, Chinese patent CN219679138U discloses an electromagnetic shielding room that is easy to disassemble and install, including a side panel, a bottom panel is installed at the lower end of the side panel, a top panel is installed at the upper end of the side panel, the side panel is fixedly connected to the bottom panel and the top panel through a convenient disassembly and assembly mechanism, a mounting plate is installed on the side of the side panel, and a door panel automatic closing mechanism is installed on the side of the mounting plate, and the door panel automatic closing mechanism includes an elastic When the staff needs to enter the electromagnetic shielding room to work, they only need to pull the handle with force, and the handle pulls the door panel body, so that the block will squeeze the bayonet, so that the bayonet compression spring is embedded in the door frame, and the door panel body can be opened through the rotating shaft. The above patent sets a convenient disassembly and assembly mechanism, which can facilitate the disassembly and assembly of the side panels of the electromagnetic shielding room, but the quick disassembly of the electromagnetic shielding room is limited to the side panels and other parts cannot be disassembled, which is not conducive to the overall disassembly and relocation.
