Description

Technical Field

[0001] This utility model relates to the field of microwave absorbing material installation technology, specifically a microwave absorbing material bonding and fastening device. Background Technology

[0002] A microwave anechoic chamber, also known as an absorbing chamber or radio wave anechoic chamber, is a special room composed of absorbing materials and a metal shield. It has a pure electromagnetic environment, and radar and electronic product testing in the anechoic chamber can be free from clutter interference, improving the accuracy and efficiency of the test.

[0003] Currently, when multiple absorbing materials are manually pasted onto a metal shielding shell, it is easy for them to be pasted crookedly, which may result in the absorbing materials not completely covering the metal shielding shell, thus affecting the testing of electronic products. To address this, we propose a device for pasting and fastening absorbing materials. Utility Model Content

[0004] The purpose of this invention is to provide a device for bonding and fastening microwave absorbing materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for bonding and fastening microwave absorbing material, comprising microwave absorbing material and a shielding shell;

[0006] The absorbing material is bonded to the shielding plate, and the absorbing material and the shielding plate have the same area.

[0007] The shielding plate is provided with shielding rods that penetrate the shielding shell on all four sides of the left side.

[0008] The shielding plate is in contact with the shielding shell;

[0009] The shielding housing is uniformly provided with fixing components that are connected to the shielding rod.

[0010] As a preferred embodiment of the wave-absorbing material bonding and fastening device of this utility model, the fixing component includes a fixing frame disposed on the outside of the shielding shell, and the fixing frame is provided with bolts for connecting to the shielding rod.

[0011] In a preferred embodiment of the wave-absorbing material bonding and fastening device of this utility model, the inner ring of the fixing frame is in contact with the shielding rod, and the shielding rod extends to the left side of the fixing frame.

[0012] In a preferred embodiment of the wave-absorbing material bonding and fastening device of this utility model, a shielding cover is attached to the left side of the shielding shell, and the shielding rod, fixing frame and bolts are all located inside the shielding cover.

[0013] As a preferred embodiment of the wave-absorbing material bonding and fastening device of this utility model, the shielding cover is provided with connecting blocks at both the upper and lower ends, and a reset component is provided at the right end of each connecting block.

[0014] In a preferred embodiment of the microwave absorbing material bonding and fastening device of this utility model, the reset component includes a movable rod, on which an installation rod is slidably sleeved, and a reset spring connected to the movable rod is transversely arranged inside the installation rod.

[0015] In a preferred embodiment of the wave-absorbing material bonding and fastening device of this utility model, the movable rod is connected to the connecting block, and the mounting rod is disposed on the shielding shell.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting a shielding plate with the same area as the absorbing material, it is easy to align and paste the absorbing material onto the shielding plate. Then, the shielding plate is pressed against the shielding shell, and the shielding rod penetrating the shielding shell is fixed by the fixing component. The shielding plate can then be installed. Repeat the above steps to install multiple shielding plates. Since the shielding plate is positioned by the shielding rod, it will not be skewed, so the absorbing material that is aligned and pasted on the shielding plate will not be skewed, thus ensuring that the absorbing material can completely cover the shielding shell.

[0018] 2. By setting up a shielding cover and a reset component, the shielding rod and the fixed frame can be covered, avoiding the shielding effect being affected by gaps between the shielding rod and the fixed frame. In addition, the reset component allows the shielding cover to move laterally without affecting the installation and removal of bolts. Attached Figure Description

[0023] 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.

[0024] As mentioned in the background section, when manually attaching multiple absorbing materials to a metal shielding shell in existing technologies, misalignment is common. This invention proposes a device for attaching and securing absorbing materials.

[0025] Example 1

[0026] Reference Figures 1 to 3 A device for bonding and fastening microwave absorbing material includes microwave absorbing material 1 and shielding shell 2;

[0027] The absorbing material 1 is bonded to the shielding plate 3, and the absorbing material 1 and the shielding plate 3 have the same area, which makes it easy to align and bond the absorbing material 1 to the shielding plate 3.

[0028] The shielding plate 3 is provided with shielding rods 4 that penetrate the shielding housing 2 on all four sides of the left side. These rods can be used to position the shielding plate 3 so that all the shielding plates 3 on the shielding housing 2 can be installed in an aligned manner.

[0029] The shielding plate 3 is in contact with the shielding housing 2;

[0030] The shielding housing 2 is uniformly provided with fixing components that are connected to the shielding rod 4.

[0031] The fixing component includes a fixing frame 5 set on the outside of the shielding housing 2. The fixing frame 5 is provided with bolts 6 that are connected to the shielding rod 4. The bolts 6 fix the fixing frame 5 to the shielding rod 4, thereby fixing the shielding plate 3.

[0032] The inner ring of the fixing frame 5 is in contact with the shielding rod 4, and the shielding rod 4 extends to the left side of the fixing frame 5, so as to pull the shielding rod 4 from the left side of the shielding housing 2 to keep the shielding plate 3 attached to the shielding housing 2.

[0033] The shielding housing 2 is fitted with a shielding cover 7 on the left side. The shielding rod 4, the fixing frame 5 and the bolts 6 are all located inside the shielding cover 7, which can cover the shielding rod 4 and the fixing frame 5, and avoid the shielding effect being affected by gaps between the shielding rod 4 and the fixing frame 5.

[0034] The shielding cover 7 is provided with connecting blocks 8 at both the top and bottom ends, and a reset component is provided at the right end of each connecting block 8.

[0035] Example 2

[0036] Reference Figures 1 to 3 The reset assembly includes a movable rod 9, on which a mounting rod 10 is slidably sleeved. A reset spring 11 connected to the movable rod 9 is arranged laterally inside the mounting rod 10. The movable rod 9 is connected to the connecting block 8. The mounting rod 10 is set on the shielding housing 2. Pulling the shielding cover 7 to the left causes the connecting block 8 to drive the movable rod 9 to stretch the reset spring 11, thus exposing the shielding rod 4, the fixing frame 5, and the bolt 6, thereby not affecting the disassembly and assembly of the bolt 6.

[0037] The rest of the structure is the same as in Example 1.

[0038] Align and paste the absorbing material 1 onto the shielding plate 3, then press the shielding plate 3 against the shielding shell 2. By fixing the shielding rod 4 that penetrates the shielding shell 2, the shielding plate 3 can be installed. Repeat the above steps to install multiple shielding plates 3. Since the shielding plate 3 is positioned by the shielding rod 4, it will not be skewed, thus ensuring that the absorbing material 1 aligned and pasted on the shielding plate 3 will not be skewed, thereby ensuring that the absorbing material 1 can completely cover the shielding shell 2.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
