Description

Technical Field

[0001] This utility model relates to the field of microwave antennas, and in particular to an integrated center disk and a large-aperture microwave antenna. Background Technology

[0002] Traditional large-aperture microwave antennas typically employ a "small center plate + rear ring + mounting bracket + telescopic rod" structure for installation. This structure presents the following problems:

[0003] 1. However, when a larger ODU needs to be installed, the limited load-bearing capacity of the small center plate may cause cracks to appear on the top of the reflector.

[0004] 2. Due to the limited space caused by the installation of pull rods and hanging parts on the left and right sides of the rear ring, medium and large ODUs cannot be installed. Even if they can be installed, there are problems with the difficulty in adjusting the left and right rotation angle and installation.

[0005] 3. Due to insufficient strength of the back ring and other components, the antenna wobbles significantly, resulting in poor structural stability and making it difficult to adjust during alignment.

[0027] Reference Figures 1 to 2 An integrated center plate includes a mounting base 10, a first connecting base 20, and a second connecting base 30;

[0028] Mounting base 10 is connected to the rear end of the reflective surface;

[0029] The first connecting seat 20 is integrally formed on one side of the mounting seat 10 and is used to connect the tie rod assembly 40;

[0030] The second connecting seat 30 is integrally formed on the other side of the mounting seat 10 and is used to connect the hanger assembly 50.

[0031] In this utility model, as a preferred embodiment of the center plate, the mounting base 10, the first connecting base 20, and the second connecting base 30 are integrally die-cast from aluminum alloy. In use, the mounting base 10 is first connected to the reflective surface of the microwave antenna body, specifically to the rear end of the reflective surface. Then, the pull rod assembly 40 and the hanger assembly 50 are respectively mounted on the first connecting base 20 and the second connecting base 30, so that the microwave antenna body is mounted on the mounting position via the pull rod assembly 40 and the hanger assembly 50. The advantages of this utility model are: the above structure makes the center plate structure more compact and robust, and it eliminates the need for a back ring, saving costs while facilitating installation and disassembly.
