Description

Technical Field

[0001] The utility model belongs to the technical field of microwave darkrooms, and in particular relates to a portable and foldable microwave darkroom. Background Art

[0002] A microwave anechoic chamber, also known as an anechoic chamber, a reflectionless chamber, or an anechoic chamber, is an electromagnetically shielded room in which absorbing materials are laid along the inner walls (walls, floor, ceiling, etc.). This effectively absorbs incident electromagnetic waves, reducing or eliminating reflection and scattering, thereby creating the free-space conditions required for antenna measurement. Microwave anechoic chambers are widely used as an ideal location for measuring antenna parameters, as well as electromagnetic wave diffraction, scattering, and radiation characteristics.

[0003] When staff need to use a microwave darkroom to detect equipment, they need to go to a designated location and cannot detect it anytime and anywhere. Traditional microwave darkrooms are large in size, and it is troublesome to disassemble and install them during the movement process, and they are not convenient to carry. Therefore, we proposed a foldable microwave darkroom that is easy to carry. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable microwave darkroom that is easy to carry. By setting up a folding plate 2, the volume of the microwave darkroom after folding is greatly reduced, which is convenient for users to carry and use. It solves the problem that existing staff need to go to a designated location to use the microwave darkroom for detection equipment and cannot detect anytime and anywhere. The traditional microwave darkroom is large in volume, and it is troublesome to disassemble and install the microwave darkroom during the movement process, making it inconvenient to carry.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a foldable microwave darkroom that is easy to carry, including a base and a closing component, wherein the left and right sides of the base are fixedly connected to a fixed block two, the tops of the two fixed blocks two are rotatably connected to a folding plate two, the tops of the two folding plates two are rotatably connected to a folding plate one, the tops of the two folding plates one are rotatably connected to a fixed block one, and the two fixed blocks one are fixedly connected to a box cover on the side close to each other, the closing component includes a baffle, a limiting component is provided on the front of the box cover, the limiting component includes an insert block, a removable plate two is provided on the back of the base, a fixing component is provided inside the removable plate two, and the fixing component includes an L-shaped plate, and the number of the L-shaped plates is two. By providing the folding plate two, specifically, the connection between the folding plate one and the folding plate two on both sides of the pushing device is moved toward the center, and the folding plates two on both sides are rotated at the end of the base, thereby driving the box cover to move downward, and the folding plate one and the folding plate two are folded. The volume of the microwave darkroom after folding is greatly reduced, and it is convenient for users to carry and use.
