Description

Technical Field

[0001] This utility model belongs to the field of microwave absorbing materials technology, specifically relating to a high-pointed cone-shaped microwave absorbing structure. Background Technology

[0002] Absorbing materials are widely used in microwave anechoic chambers and radio wave anechoic chambers to absorb electromagnetic waves. In microwave anechoic chambers, especially large ones, most domestic manufacturers produce cone-shaped absorbing materials larger than 600mm×600mm×500mm. These materials use a flat absorbing base with a four-sided pyramidal absorbing wedge structure. Each base of this type of absorbing material is equipped with four four-sided pyramids larger than 420mm. During installation, the absorbing material base is first fixed to the back plate with screws, and then the cone-shaped wedges are disassembled one by one. Do not insert the cone into the slot on the flat base to complete the assembly. The cone is too large and heavy, which is inconvenient both during assembly and subsequent maintenance. The cone itself is heavy, and the part installed on the ceiling of the darkroom is at great risk of falling off due to its own weight, which is extremely dangerous and poses a great safety hazard. When this size of absorbing material is installed on the wall, the cone is prone to drooping due to gravity. It is also at risk of falling off due to seasonal temperature changes. Moreover, the drooping of the absorbing cone will have a very large impact on the darkroom, indirectly causing significant economic losses.

[0003] Each base is independent, and gaps can easily appear during installation, which greatly affects the performance of the darkroom. When there is a deviation during installation, the angle of the base cannot be adjusted. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-pointed cone-shaped absorbing structure. By setting a groove on the first side of the first base plate and setting a protrusion on the second side of the first base plate corresponding to the groove, the first base plate and the second base plate are staggered to form a stepped part. When installing the high-pointed cone-shaped absorbing structure, it is directly fixed to the back plate of the absorbing material by screws passing through the mounting holes. In this way, each four-sided cone is fixed to the back plate with screws, directly eliminating the risk of natural detachment and the phenomenon of drooping.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-pointed cone-shaped microwave absorbing structure, wherein the high-pointed cone-shaped microwave absorbing structure comprises:
