It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] Please refer to Figure 1-Figure 10 , an antenna horizontal azimuth electric adjustment mechanism, comprising:

[0051] Pole 100;

[0055] A horizontal angle adjustment mechanism 500, the horizontal angle adjustment mechanism 500 includes a first mounting platform 510, a first motor 520, a worm gear 530 and a worm 540, the first motor 520 is fixed on the first mounting platform 510, the first mounting platform 510 is connected to the upper holding rod mechanism 300, the first motor 520 drives the worm gear 540 to drive the worm gear 530 to rotate, the rotation center of the worm gear 530 is provided with an output shaft 531, the output shaft 531 is connected to the upper antenna box connecting frame 400, and the configuration direction of the first motor 520 deviates from the connection line between the upper holding rod mechanism 300 and the upper antenna box connecting frame 400;

[0057] A lower antenna box connecting frame 700, the lower antenna box connecting frame 700 is connected to the lower end of the antenna box 200;

[0058] The horizontally rotating clutch mechanism 800 locks the lower holding rod mechanism 600 and the lower antenna box connecting frame 700 through clutch, or allows the lower antenna box connecting frame 700 to rotate freely horizontally.

[0059] The antenna box 200 is connected to the upper end of the pole 100 through the upper antenna box connecting frame 400, the horizontal angle adjustment mechanism 500 and the upper holding rod mechanism 300 in sequence, and the antenna box 200 is connected to the lower end of the pole 100 through the lower antenna box connecting frame 700, the horizontal rotation clutch mechanism 800 and the lower holding rod mechanism 600 in sequence. The lower end is a clutch instead of a reduction box, that is, there is only a reduction box composed of a worm 540 and a worm wheel 530, and the upper and lower parts can rotate horizontally synchronously without interference. The matching structural parts of the reduction box and the clutch are relatively small, and the first motor 520 of the upper horizontal angle adjustment mechanism 500 deviates from the connection line between the upper holding rod mechanism 300 and the upper antenna box connecting frame 400, which reduces the upper end spacing of the pole 100 and the antenna box 200, thereby having better wind load resistance and increasing the service life of the reduction box.

The second motor 830 is perpendicular to the moving direction of the direction-changing telescopic mechanism 840, which reduces the distance between the vertical pole 100 and the lower end of the antenna box 200, further improves the wind load resistance, shares the side wind load of the reduction box, and further prolongs the service life of the mechanism.
