Description

Technical Field

[0001] The utility model belongs to the technical field of wave-absorbing material installation, and in particular relates to a side wall wave-absorbing material fixing structure of a large darkroom. Background Art

[0002] When the electromagnetic compatibility chamber is used for product testing, because the types and sizes of products are different, including various large military equipment such as aircraft, the test space of these equipment is relatively large, so the size of the chamber needs to reach a height of more than 20m. At this height, the installation of absorbing materials inside the chamber is a problem that needs to be paid attention to at present;

[0003] At present, the common installation method is screw installation, which is firm and strong, but has the problem of inconvenient disassembly and cumbersome installation. The inconvenience of disassembly is not conducive to the reuse of absorbing materials, and the cumbersome installation leads to low efficiency. There is also a method of using glue to install absorbing materials, but because the glue is volatile, when the volatile substances in the air reach a certain concentration, it may also cause an explosion, causing life-threatening;

[0004] Therefore, it is necessary to optimize and improve the structure of the installation of the side wall absorbing material. Utility Model Content

[0005] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a fixing structure of a side wall absorbing material for a large darkroom.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A side wall absorbing material fixing structure for a large darkroom, comprising a steel keel fixedly mounted on a wall steel plate, wherein the cross section of the steel keel is U-shaped, and the upper and lower sides of the steel keel are integrally connected with a clamping edge, and the clamping edge is perpendicular to the steel keel;

[0008] The card edge is hung with a back plate, a folded edge matching the size of the card edge is integrally connected to the side of the back plate, and a wave absorbing material is installed on the back plate.

[0009] It is further defined that the steel keel is provided with a through hole, and a double-headed screw is installed between two adjacent upper and lower steel keels, and both ends of the double-headed screw are threadedly connected with interference nuts. With such a design, when the interference nuts contact the steel keels on the upper and lower sides, the double-headed screw can support the steel keel, that is, it serves the purpose of auxiliary support.

[0010] It is further defined that the back panel is provided with a hanging hole, a boss with a size matching the hanging hole is installed on the back side of the absorbing material, the boss is provided with a fork, and a conical chamfer is installed on the outer side of the boss. With this design, by pressing the hanging hole into the boss, the back panel can be fixed under the effect of the conical chamfer, thereby realizing the installation and fixation between the back panel and the absorbing material.

[0011] It is further defined that one of the back panels is provided with at least two hanging holes in the horizontal direction. Such a design ensures the installation level of the back panel and the installation strength between the back panel and the absorbing material.

[0012] It is further defined that the hanging hole is a waist-shaped hole, and such a design improves installation adaptability.

[0013] The beneficial effects of adopting the utility model are:

[0014] The structural design of the utility model can directly install the absorbing material in a hanging manner, which is simple and convenient to install and easy to disassemble and reuse.

[0015] With the structural design of the utility model, the back plate and the wave-absorbing material are installed by gluing, so there is no problem of explosion caused by volatile substances. BRIEF DESCRIPTION OF THE DRAWINGS
