[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please refer to Figures 1-4. This utility model is a microwave absorbing plate for a walkway in a microwave anechoic chamber, comprising:

[0028] The main body of the wave absorbing board 11;

[0029] The auxiliary connection assembly includes a fixing rod 21, a plug-in rod 22, a mounting rod 23, a fixing block 25, and a connecting frame 27. The fixing rod 21 is embedded in both sides of one end of the absorber plate body 11, the plug-in rod 22 is fixed to the outer end of the fixing rod 21, the mounting rod 23 is embedded in both sides of the other end of the absorber plate body 11, the fixing block 25 is fixed to both sides of one edge of the top of the absorber plate body 11 and is located above the plug-in rod 22, and the connecting frame 27 is fixed to both sides of the other edge of the top of the absorber plate body 11 and is located above the mounting rod 23.

[0030] The fixing rod 21 is used to connect the plug rod 22, the plug rod 22 is used to connect with the mounting rod 23, the mounting rod 23 is used to open the plug groove 24, and the fixing block 25 is used to snap the connecting frame 27, so that the fixed block 25 and the connecting frame 27 after snapping are further connected and limited to the installed absorber plate body 11.

[0031] An insertion groove 24 is provided on the inner side of the outer end of the mounting rod 23. The insertion groove 24 is inserted into the insertion rod 22. A friction pad is fixedly connected to the inner surface of the insertion groove 24.

[0032] The insertion slot 24 is used for inserting the insertion rod 22 into the mounting rod 23. The friction pad is used to increase the friction between the insertion rod 22 and the insertion slot 24, so that when the insertion rod 22 is inserted into the insertion slot 24, the friction pad further stabilizes the connection between the insertion rod 22 and the mounting rod 23.

[0033] The top of the fixing block 25 is provided with a snap-fit ​​groove 26, which snaps into the protruding end above the connecting frame 27;

[0034] A connecting groove 28 is provided on the top surface of the protruding end of the connecting frame 27 and on both sides of the upper side of the snap-fit ​​groove 26. A limit frame 29 is snapped into the inner side of the connecting groove 28.

[0035] The snap-fit ​​groove 26 is used for insertion of the protruding end above the connecting frame 27, and the connecting groove 28 is used for snap-fit ​​of the limiting frame 29. The limiting frame 29 further limits the fixed block 25 and the connecting frame 27 after snap-fit. When the connecting frame 27 and the snap-fit ​​groove 26 are snap-fitted together, the connecting grooves 28 on the surfaces of the two are aligned. The limiting frame 29 is inserted into the connecting groove 28, so that the limiting frame 29 limits the connecting frame 27 after snap-fit, further stabilizing the connection between the absorbing plates.

[0036] Working principle: When the components are not in use and the absorber panels are not installed, the absorber panel body 11 is installed by hand using conductive adhesive. At this time, the absorber panel body 11 drives the plug rod 22 to be inserted into the plug groove 24. Since the friction pad is fixedly connected to the inner surface of the plug groove 24, the friction pad further stabilizes the connection between the plug rod 22 and the mounting rod 23 through friction. The absorber panel body 11 drives the connecting frame 27 to move synchronously, so that the connecting frame 27 is engaged with the snap-fit ​​groove 26, and the connecting grooves 28 on the surfaces of the two are aligned. Hold the limiting frame 29 by hand and insert the limiting frame 29 into the connecting groove 28, so that the limiting frame 29 limits the connection of the snap-fit ​​connecting frame 27, further stabilizing the connection between the absorber panels, thereby preventing the absorber panel body 11 from separating from the designated position due to long-term use of adhesive.

[0037] Please refer to Figures 1-3. This embodiment, based on the above embodiments, further includes:

[0038] Protection components;

[0039] The protective components include mounting slots 31, connecting rods 32, and protective covers 33. The mounting slots 31 are arranged in a set and are located on both sides of one edge of the top of the absorber plate body 11 and on one side of the periphery of the fixing block 25. The connecting rods 32 are inserted into the inner side of the mounting slots 31. The protective covers 33 are fixed to the top of each set of connecting rods 32 and the other edge of the top of the absorber plate body 11.

[0040] The mounting slot 31 is used for inserting the docking rod 32. There are three mounting slots 31 in total. The docking rod 32 is used for connecting the protective cover 33 and the main body 11 of the wave-absorbing plate. The protective cover 33 is used to prevent workers from colliding with the fixing block 25 and the connecting frame 27.

[0041] The protective cover 33 covers the outside of the fixing block 25 and the connecting frame 27, and a soft pad is fixedly connected to the outer surface of the protective cover 33;

[0042] One protective cover 33 is fixedly connected to an adsorption block 34 at the opposite end, and the other protective cover 33 is fixedly connected to a magnetic block 35 at the bottom end. The magnetic block 35 is attracted to the adsorption block 34.

[0043] The soft pad is used to increase the softness of the protective cover 33 and prevent the protective cover 33 from causing injury to the staff. The magnetic block 35 is attracted to the adsorption block 34 by magnetic force, so that the two protective covers 33 are connected together by magnetic force. In this way, the fixed block 25, the connecting frame 27 and the staff outside are separated by the protective cover 33, preventing the staff from colliding with the fixed block 25 and the connecting frame 27.

[0044] Working principle: When the component is not in use, the docking rod 32 is not inserted into the mounting slot 31, and the connecting frame 27 is located in the snap-fit ​​slot 26. When the limiting frame 29 is snapped into the connecting slot 28, hold one side of the protective cover 33 by hand and insert the docking rod 32 into the mounting slot 31, so that the protective cover 33 is connected to the main body 11 of the wave-absorbing plate. At the same time, the magnetic block 35 is attracted to the adsorption block 34 by magnetic force, so that the two protective covers 33 are connected together by magnetic force, causing the protective cover 33 to cover the fixing block 25, the connecting frame 27 and the limiting frame 29, separating the fixing block 25, the connecting frame 27 from the outside personnel.
