[0002] The electromagnetic shielding tent that is easy to disassemble is a tent product that combines electromagnetic shielding technology with a convenient disassembly and assembly design. It uses specific materials and technical means to achieve reflection, absorption or scattering of electromagnetic waves, thereby effectively preventing the penetration of electromagnetic waves and protecting the equipment or personnel inside the tent from electromagnetic interference or radiation. At the same time, its structural design focuses on the convenience of disassembly and assembly, allowing users to complete the construction and disassembly of the tent in a short time.

In this utility model, when a person needs to enter or exit the tent, the pull rope is pulled to drive the rack to move, the rack movement drives the gear to rotate, so that the support shaft rotates, the anti-interference shielding door curtain is rolled into the storage cavity, and the coil spring is tightened at the same time, when the person enters or exits the tent, the pull rope is released, and under the dual action of the counterweight block and the coil spring, the anti-interference shielding door curtain is quickly lowered and closed in time, thereby ensuring the shielding ability of the tent body. However, the device fails to facilitate the disassembly and transportation of the electromagnetic shielding tent, and the disassembly and assembly process is cumbersome and time-consuming due to the complex structure and numerous components, thereby reducing the efficiency of use.

[0004] The physical effects such as friction and scratching during the disassembly and assembly of existing electromagnetic shielding tents cause wear and even damage to the shielding cloth and the tarpaulin surface. At the same time, most of the existing electromagnetic shielding tents use traditional metal materials or other non-metallic materials as the shielding layer. Traditional metal materials may have problems such as easy rust and corrosion, while non-metallic materials may gradually age or wear during long-term use, resulting in a decrease in shielding performance, which in turn affects the technical problems of its electromagnetic shielding.

After the frame is spliced, the operator puts the tarpaulin 1 on the outside of the frame, and at the same time, the tarpaulin 1 is tied and connected to the frame through multiple straps, and then the rod body 4 is rotated to extend the movable columns 5 at both ends of the rod body 4, so as to support the tarpaulin 1 for use. At the same time, the electromagnetic is shielded by the shielding cloth 3. The shielding cloth 3 is made of metal foil. The metal foil achieves the shielding effect by reflecting, absorbing and scattering electromagnetic waves. The tarpaulin 1 is made of waterproof material to effectively prevent water penetration, thereby protecting the inside of the tarpaulin 1 from drying and extending the service life of the tarpaulin 1.
