Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to a multi-layer composite high-efficiency wave-absorbing plate. Background Art

[0002] Absorbing materials refer to a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves. Studies have confirmed that ferrite absorbing materials have the best performance.

[0003] At present, in order to better apply the absorbing materials, the absorbing materials and the wave-transmitting materials are usually combined into a multi-layer composite board, which not only has a good absorbing effect but is also relatively strong.

[0004] However, the absorbing plates in the prior art are mostly installed on the frame by bolts, but there is a lack of connection between each two plates, which may cause electromagnetic waves to pass through the gaps, thereby affecting the overall absorbing properties. Therefore, the utility model proposes a multi-layer composite high-efficiency absorbing plate to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-layer composite high-efficiency absorbing plate to solve the problem that the absorbing plates in the prior art mentioned in the above background technology lack connection between each other during installation, resulting in electromagnetic waves passing through the gaps, thereby affecting the overall absorbing properties.

[0006] In order to achieve the above object, the utility model provides the following technical solution: a multi-layer composite high-efficiency wave-absorbing plate, the multi-layer composite high-efficiency wave-absorbing plate comprising:

[0007] An absorbing plate body, one end of the absorbing plate body is fixedly connected with a positioning sleeve, one side of the positioning sleeve is fixedly connected with a limiting plate, the other end of the absorbing plate body is fixedly connected with a fixing block, one side of the positioning sleeve is provided with a positioning groove for plugging a fixing block on another absorbing plate body, one side of the fixing block is provided with a mounting groove, one side of the mounting groove is fixedly connected with a plurality of No. 1 springs, one end of the No. 1 spring is fixedly connected with a mounting plate, one side of the mounting plate is fixedly connected with a plurality of No. 2 springs, and one end of the No. 2 spring is fixedly connected with a limiting rod.

[0008] Preferably, a plurality of telescopic rods are fixedly connected to one side of the mounting groove, and the telescopic rods are fixedly connected to the mounting plate and plugged into the No. 1 spring.

[0009] Preferably, a plurality of guide pillars are slidably plugged into one side of the mounting plate, the guide pillars are fixedly connected to the limiting rod and plugged into the No. 2 spring, and one end of the limiting rod is fixedly connected to a convex plate.

[0010] Preferably, a pressure plate is slidably inserted into one side of the mounting plate, and the pressure plate is slidably inserted into the fixing block.

[0011] Preferably, a sliding groove for the pressure plate to slide is formed on one side of the fixing block, and a notch for the pressure plate to be plugged into is formed on one side of the limiting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model inserts the fixing block at one end of one of the absorbing plate bodies into the positioning sleeve of the absorbing plate body that has been fixed. After the insertion is in place, the mounting plate will pop out of the mounting slot. After the mounting plate pops out of the mounting slot, the limiting rod will slide toward the limiting plate end under the action of the second spring, so that the unfixed absorbing plate body and the fixed absorbing plate body are fixed together, so that the gap between the two absorbing plate bodies is blocked, and this can also facilitate the better installation of the bolts of the unfixed absorbing plate body, thus solving the problem in the prior art that the electromagnetic waves may pass through the gaps when the absorbing plates are installed, thereby affecting the overall absorbing characteristics.
