Problems solved by technology

[0003] However, when the multi-frequency manual portable antenna on the market is from the storage state to the unfolded state, the angle between the antenna surface and the feed source is not easy to locate. After the angle between the antenna surface and the feed source is positioned, the antenna surface pitch angle When adjusting and locking, most of them need multiple operations to complete coarse adjustment, fine adjustment and locking, which not only wastes time but also has poor adjustment accuracy and poor stability

Embodiment 1

[0040] Such as Figure 1-8 As shown, this embodiment provides an antenna plane pitch angle adjustment and locking turntable, which includes an antenna support 1 and a support assembly, and the support assembly includes a support 2, a pitch transmission shaft 10, an adjustment assembly and a locking assembly;

[0041] See figure 2 , the right end of the support 2 is provided with a right pitch lug 5, and the right pitch lug 5 is rotatably connected to the antenna bracket 1, and a reducer flange 9 is fixed inside the right pitch lug 5 And the planetary reducer 6, the right end of the planetary reducer 6 is provided with a reducer end cover 12, and the right side of the reducer end cover 12 is provided with a folding handwheel 7, and the folding handwheel 7 and the planetary reducer 6 are connected by hand The wheel connection shaft 8 is axially connected, and the output shaft of the planetary reducer 6 can be driven to rotate by rotating and folding the hand wheel 7. The outpu...

Embodiment 2

[0047] Such as figure 1 and Figure 6 As shown, on the basis of Embodiment 1, this embodiment discloses a portable antenna, including an antenna surface 3, a feed support arm 4, and the antenna surface pitch angle adjustment and locking turntable disclosed in Embodiment 1. The antenna main body 31 and the five-split 32 are spliced, and then the antenna surface 3 is fixedly connected to the antenna support 1, and the feed support arm 4 is fixedly connected to the left side plate 29 and the right side plate 11, and the end of the feed support arm 4 is provided with Feed connection board 27 .

[0048] When a kind of portable antenna disclosed in this embodiment is stored, such as Figure 9 and Figure 11 As shown, except for the main body 31 of the antenna surface 3, the other five-split lobes 32 are all removed. The pin head of the self-locking knob 25 is not inserted into the pin hole 30, and the pitch angle between the antenna bracket 1 and the feed arm 4 can be adjusted b...

Abstract

The invention belongs to the technical field of antennas, and particularly discloses an antenna surface pitch angle adjusting and locking rotary table and a portable antenna. The portable antenna comprises an antenna surface, a feed source support arm and an antenna surface pitch angle adjusting and locking rotary table. The antenna surface pitch angle adjusting and locking rotary table further comprises an antenna holder and a support assembly. The support assembly comprises a support, a pitching transmission shaft, an adjusting assembly and a locking assembly. By arranging a self-locking knob, a feed source angle limiting block and a pitching range limiting block, the relative position of the antenna surface and the feed source support arm can be fixed when the antenna is changed from a storage state to an unfolding state, the satellite alignment precision is high, and the stability is good.

Description

technical field [0001] The application belongs to the technical field of antennas, and in particular relates to an antenna surface pitch angle adjustment and locking turntable and a portable antenna. Background technique [0002] Satellite communication equipment has become an indispensable electronic device in the field of modern science and technology. Satellite signals have the advantages of wide coverage and signal transmission not affected by terrain. They have been widely used in field communications. Since the development of star communication structure technology, many satellite communication antennas There are endless supporting structures, and the ground, vehicle-mounted, ship-mounted, folded, and assembled structures also have their own advantages and disadvantages. [0003] However, when the multi-frequency manual portable antenna on the market is from the storage state to the unfolded state, the angle between the antenna surface and the feed source is not easy t...
