Description

Technical Field

[0001] The utility model relates to the technical field of wave-absorbing materials, in particular to a wave-absorbing composite material. Background Art

[0002] With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. At airports, flights are delayed due to electromagnetic interference and cannot take off; in hospitals, mobile phones often interfere with the normal operation of various electronic diagnostic and treatment equipment. Therefore, controlling electromagnetic pollution and finding a material that can resist and weaken electromagnetic radiation - absorbing materials, has become a major topic in materials science. The so-called absorbing material refers to a type of material that can absorb or greatly weaken the electromagnetic wave energy received on its surface, thereby reducing electromagnetic interference.

[0003] Existing absorbing composite materials are usually used in conjunction with electromagnetic shielding plates to ensure that electromagnetic waves are absorbed by the absorbing material body to avoid leakage. However, the absorbing composite material is usually a fixed structure with the electromagnetic shielding plate. When one of the electromagnetic shielding plate or the absorbing composite material is damaged, the entire structure must be replaced, which greatly increases the replacement cost. In view of this, we propose an absorbing composite material. Utility Model Content

[0004] The purpose of the utility model is to provide a wave-absorbing composite material to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wave-absorbing composite material, comprising:

[0007] An absorbing material body, wherein an electromagnetic shielding plate is disposed on the top surface of the absorbing material body, a plurality of sleeve holes are provided on the bottom surface of the electromagnetic shielding plate, an annular groove is provided on the inner side walls of the plurality of sleeve holes, two side grooves are disposed on the plurality of sleeve holes, and the plurality of side grooves are respectively connected to the plurality of sleeve holes;

[0008] A plurality of sleeve columns, the plurality of sleeve columns are rotatably mounted on the top surface of the absorbing material body, the plurality of sleeve columns are movably sleeved with the plurality of sleeve holes, and both sides of the plurality of sleeve columns are fixedly mounted with clamping blocks, and the plurality of clamping blocks slide in the plurality of annular clamping grooves respectively;

[0009] A plurality of groups of limiting components are arranged on the absorbing material body and are used to limit a plurality of sleeve columns.

[0010] Preferably, the limiting assembly includes an inner cavity, which is arranged in a main body of the absorbing material, a slide plate is slidably connected in the inner cavity, two slide grooves are provided on the top surface of the main body of the absorbing material, the two slide grooves are connected to the inner cavity, the positions of the two slide grooves and the two side grooves correspond to each other, limiting columns are slidably connected in the two slide grooves, the top ends of the two limiting columns are respectively movably sleeved in the two side grooves, the slide plate is slidably connected in the inner cavity, and the top surface of the slide plate is fixedly connected to the bottom ends of the two limiting columns.

[0011] Preferably, a lifting spring is fixedly mounted on the inner bottom surface of the inner cavity, and the top end of the lifting spring is fixedly connected to the bottom surface of the slide plate.

[0012] Preferably, an outer side wall of the absorbing material body is provided with an adjustment groove, an adjustment rod is slidably connected in the adjustment groove, and one end of the adjustment rod is fixedly connected to one side of the slide plate.

[0013] Preferably, a square groove is formed on the top surface of the sleeve.

[0014] Preferably, the clamping block is a rectangular structure, the side groove is a rectangular groove, and the specifications of the clamping block match those of the side groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When disassembling the electromagnetic shielding plate or the absorbing material body, the absorbing composite material is pressed down on the adjusting rod, which drives the slide plate to move downward. When the slide plate moves, the limiting column is driven to disengage from the side groove. When the limiting column is disengaged from the side groove and moves into the inner cavity, the limiting of the card block is released. At this time, the sleeve column is rotated. When the card block is rotated to the corresponding side groove position, the absorbing material body can be separated from the electromagnetic shielding plate, thereby realizing the replacement of the absorbing material body or the electromagnetic shielding plate, which is more practical.

[0017] 2. When installing the absorbing material body and the electromagnetic shielding plate of the absorbing composite material, the side groove is rotated to the position corresponding to the card block, and the electromagnetic shielding plate is placed above the absorbing material body. At this time, the sleeve column will be sleeved in the sleeve hole. After the sleeve column is sleeved in the sleeve hole, the card block will enter the annular slot through the side groove. At this time, the sleeve column is rotated. When the side groove and the card block are misaligned, the electromagnetic shielding plate will be limited above the absorbing material body through the cooperation of the annular slot and the card block. After the side groove and the card block are misaligned, the lifting spring will lift the slide plate. At this time, the limiting column will be sleeved in the corresponding side groove, thereby blocking the card block, preventing the card block from rotating to the side groove position to cause the absorbing material body and the electromagnetic shielding plate to fall off, thereby enhancing the stability and fixity between the absorbing material body and the electromagnetic shielding plate during installation. This installation method is convenient to install and has strong fixity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Multiple groups of limiting components are arranged on the absorbing material body 1 and are used to limit the multiple sleeve columns 6.

[0033] In this embodiment, the limiting assembly includes an inner cavity 12, which is arranged in the absorbing material body 1, and a slide plate 11 is slidably connected in the inner cavity 12. Two slide grooves 8 are provided on the top surface of the absorbing material body 1, and the two slide grooves 8 are connected to the inner cavity 12. The positions of the two slide grooves 8 and the two side grooves 5 correspond to each other. The two slide grooves 8 are both slidably connected to the limiting posts 9, and the top ends of the two limiting posts 9 are respectively movably sleeved in the two side grooves 5. The inner cavity 12 is slidably connected to the slide plate 11, and the top surface of the slide plate 11 is fixedly connected to the bottom ends of the two limiting posts 9. When the slide plate 11 moves upward, the limiting posts 9 will be sleeved in the corresponding side groove 5, thereby blocking the block 7, preventing the block 7 from rotating to the side groove 5 position to cause the absorbing material body 1 and the electromagnetic shielding plate 2 to fall off, thereby enhancing the stability and fixity between the absorbing material body 1 and the electromagnetic shielding plate 2 during installation.

[0034] In this embodiment, a lifting spring 13 is fixedly installed on the inner bottom surface of the inner cavity 12, and the top of the lifting spring 13 is fixedly connected to the bottom surface of the slide plate 11. After the side groove 5 and the block 7 are misaligned, the lifting spring 13 will lift the slide plate 11.

[0035] In this embodiment, an adjustment groove 14 is provided on the outer wall of the absorbing material body 1, and an adjustment rod 15 is slidably connected in the adjustment groove 14. One end of the adjustment rod 15 is fixedly connected to one side of the slide plate 11.

When the side groove 5 and the block 7 are misaligned, the electromagnetic shielding plate 2 will be limited above the absorbing material body 1 through the cooperation of the annular groove 4 and the block 7. After the side groove 5 and the block 7 are misaligned, the lifting spring 13 will lift the slide plate 11. At this time, the limiting column 9 will be sleeved in the corresponding side groove 5, thereby blocking the block 7, preventing the block 7 from rotating to the side groove 5 position to cause the absorbing material body 1 and the electromagnetic shielding plate 2 to fall off, thereby enhancing the stability and fixity between the absorbing material body 1 and the electromagnetic shielding plate 2 during installation. This installation method is easy to install and has strong fixity.
