[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides embodiments:

[0024] A miniaturized 5G base station antenna comprises an antenna body 1, a protective box 2 is installed at the bottom end of the antenna body 1, a circuit board 4 is installed in the protective box 2, a bracket 3 is rotatably installed on one side of the protective box 2 through a damping shaft, a rotating hole is opened on the surface of the bracket 3, a worm 9 is rotatably installed in the rotating hole, a worm wheel 8 is installed on one side of the protective box 2, the worm wheel 8 is meshed with the worm 9, a damping rotating disk 11 is installed on the lower side of the bracket 3, a mounting plate 12 is installed on the lower side of the damping rotating disk 11, and an angle adjustment knob 10 is installed at one end of the worm 9.

[0025] Based on the above structure, the antenna body 1 includes an antenna and a signal amplifier, wherein the bottom connection part of the antenna passes through the upper side of the protective box 2 and is connected to the circuit board 4 in the protective box 2 for signal radio frequency. After the device is installed and fixed, by rotating the angle adjustment knob 10, the angle adjustment knob 10 drives the worm 9 to rotate, the worm 9 drives the worm gear 8 to rotate, and the worm gear 8 drives the protective box 2 to rotate. The protective box 2 adjusts the antenna body 1 to adjust the vertical angle, and at the same time drives the bracket 3 to rotate through the damping rotating disk 11, thereby driving the antenna body 1 to adjust the horizontal angle, so as to facilitate the adjustment of the angle and facilitate debugging and installation.

[0026] like Figure 2 As shown, a heat dissipation fan 5 is installed on the inner wall of the protective box 2, two air inlets are opened on the lower side of the protective box 2, and two air outlets are opened on the side of the protective box 2. The two air outlets are located on both sides of the protective box 2, and two air inlets are opened at positions close to the two air inlets of the protective box 2. The heat dissipation fan 5 draws outside air into the air inlet and discharges it through the two air outlets to form a stable air duct, which takes away the heat generated on the surface of the circuit board 4 and protects the circuit board 4 from heat dissipation.

[0027] like Figure 2 As shown, dustproof plates 6 are installed in both air inlets, and waterproof curtains 7 are installed in both air outlets. The dustproof plates 6 can prevent dust from entering the protective box 2. The waterproof curtain 7 consists of a mounting frame and a plurality of waterproof plates rotatably connected to the surface thereof. When the heat dissipation fan 5 is not in use, the waterproof plates hang down due to gravity to shield and waterproof the protective box 2. When the heat dissipation fan 5 is working, the wind resistance pressure can push the waterproof plates open to expand the angle component between the waterproof plates and the waterproof plates, thereby dissipating heat, and preventing rainwater from entering the protective box 2 through the waterproof curtain 7.

[0028] like Figure 4 As shown, a plurality of sliding grooves are provided on the lower side of the mounting plate 12, and an adjusting block 13 is slidably installed in each of the sliding grooves. A fixed block 14 is installed on the lower side of the adjusting block 13. There are four sliding grooves in total, forming a cross shape, and an adjusting block 13 and a fixed block 14 are slidably installed in each of the sliding grooves. The fixed block 14 is U-shaped for easy extrusion installation.

[0029] like Figure 4 As shown, a rotation hole is opened on one side of the mounting plate 12 , a threaded rod 15 is rotatably mounted in the rotation hole, and the adjustment block 13 is screwed and mounted on the surface of the threaded rod 15 .

[0030] like Figure 4As shown, a mounting knob 16 is installed at one end of the threaded rod 15. By rotating the mounting knob 16, the mounting knob 16 drives the threaded rod 15 to rotate, the threaded rod 15 drives the adjusting block 13 to move, and the adjusting block 13 drives the fixing block 14 to move. By sequentially adjusting multiple independent fixing blocks 14 to make them close to each other, it is convenient to fix the device in the location area where it needs to be installed, thereby achieving the effect of easy installation.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
