Detailed Implementation

[0028] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 As shown in the figure, a novel fixed antenna provided by this utility model embodiment includes a support module 1, a turntable module 2, and an antenna feed module 3. The support module 1 and the turntable module 2 are connected by a non-detachable connection. The turntable module 2 includes a housing 201 and an internal pitch transmission component and an azimuth transmission component. The pitch transmission component and the azimuth transmission component are used to adjust the pitch angle and azimuth angle of the antenna feed module 3, respectively. A turntable 6 is provided at the bottom of the turntable module 2. Several steel balls are provided between the mating surfaces of the housing 20 and the turntable 6. The turntable 6 is connected to the upper end of the support module 1 by bolts. The housing 20 of the turntable module 2 is connected to the turntable 6 through the azimuth transmission component, which is used to drive the turntable module 2 to rotate to adjust the azimuth angle and lock it. The housing 20 of the turntable module 2 is connected to the radio frequency unit 27 through the pitch transmission component. The radio frequency unit 27 is located at the bottom of the antenna feed module 3. The pitch transmission component is used to drive the radio frequency unit 27 to flip to adjust the pitch angle and lock it.

[0030] In specific assembly, the top of the RF unit 27 is connected to the antenna feed module 3 via multiple raised posts 8. The back side of the antenna surface of the antenna feed module 3 is connected to the RF unit 27 via multiple tie rods 9, which serve to fix the antenna and enhance its strength. In this embodiment, there are six raised posts, evenly distributed around the RF unit. This structure ensures the antenna feed module is installed stably.

[0031] In specific embodiments of this utility model, such as Figure 2 , 4As shown in Figure 6, the pitch transmission assembly includes a pitch handle 10, a pitch transmission mechanism, and a pitch support 7. The pitch handle 10 is connected to the input end of the pitch transmission mechanism via a pitch transmission shaft 22. The pitch transmission mechanism and the pitch transmission shaft 22 are located inside the housing 20, while the pitch handle 10 is located outside the housing 20. The output end of the pitch transmission mechanism is coaxially fixed to the pitch drive shaft 24. The lower end of the pitch support 7 is fixed to the pitch drive shaft 24, and the upper end of the pitch support 7 is fixed to the radio frequency unit 27. The radio frequency unit 27 is connected to the middle of the outer wall of the housing 20 via a pitch locking assembly 5, which is used to lock the pitch after adjustment. The pitch transmission mechanism adopts a worm gear transmission mechanism 23. When the pitch angle needs to be adjusted, rotating the pitch handle 10 drives the pitch drive shaft 22 to rotate, which in turn drives the worm gear and its meshing worm wheel to rotate. This, in turn, drives the pitch drive shaft 24, which is fixed coaxially with the worm wheel, to rotate. The pitch drive shaft 24 then drives the pitch support 7 to rotate, which in turn drives the radio frequency unit 27 and the antenna feed module 3 to adjust the pitch angle. Utilizing the self-locking characteristic of the worm gear transmission mechanism, the stability of the overall structure after adjustment can be ensured.

[0032] In specific design, such as Figure 3 As shown, the pitch locking assembly 5 includes a pitch fixing bracket 14 and a pitch locking bolt 15. The upper end of the pitch fixing bracket 14 is rotatably connected to the side wall of the radio frequency unit 27 via a connecting screw 16. A fixing washer 17 fitted on the connecting screw 16 is provided between the pitch fixing bracket 14 and the radio frequency unit 27 to increase the contact area and ensure a firm connection. A sliding groove is provided along the length of the lower middle part of the pitch fixing bracket 14. One end of the pitch locking bolt 15 passes through the sliding groove and is threaded into the side wall of the housing 20. During adjustment, the pitch locking bolt 15 can slide along the sliding groove. When locking, a locking washer 13 is provided between the mating surface of the pitch fixing bracket 14 and the housing 20 of the turntable module to increase the contact area and ensure a firm connection. During the flipping process, the pitch fixing bracket rotates around its upper end, and the lower sliding groove can rise and fall relative to the pitch locking bolt. After the pitch angle is adjusted, the pitch fixing bracket is locked in place using pitch locking bolts to further improve the stability of the structure. In actual manufacturing, pitch lugs 7 and pitch fixing brackets 14 are symmetrically arranged on both sides of the RF unit 27, which can improve the stability of the RF unit 27 and the antenna feed module 3 during the flipping process.

[0033] In specific embodiments of this utility model, such as Figure 2 , 4As shown, the azimuth transmission assembly includes an azimuth handle 11 and an azimuth transmission mechanism. The azimuth handle 11 is located outside the housing 20, and the azimuth transmission mechanism is located inside the housing 20. The azimuth handle 11 is connected to the input end of the azimuth transmission mechanism via an azimuth transmission shaft 25, and the output end of the azimuth transmission mechanism is connected to the main shaft of the turntable 6 via a gear set 26. An azimuth locking assembly is provided at the bottom of the housing 20 and the edge of the turntable 6 to lock the azimuth after adjustment. All azimuth transmission mechanisms employ worm gear transmission mechanisms 23. When azimuth angle adjustment is required, rotating the azimuth handle 11 drives the worm and its meshing worm wheel to rotate. The worm wheel then drives the main shaft of the turntable 6 to rotate via the gear set 26, causing the housing 20 and the turntable 6 to rotate relative to each other, thereby adjusting the azimuth angle. The self-locking characteristic of the worm gear transmission mechanism ensures the stability of the overall structure after adjustment.

[0034] In specific embodiments of this utility model, such as Figure 5 As shown, the azimuth locking assembly includes an upper clamping block 18, a lower clamping block 19, and an azimuth locking handle 21. The upper surface of the lower clamping block 19 is provided with two guide posts 28. The upper clamping block 18 has guide holes that mate with the guide posts 28, and the upper ends of the guide posts 28 are threadedly engaged with the bottom of the turntable 6. The azimuth locking handle 21 is L-shaped, with its vertical portion penetrating the lower clamping block 19 and threadedly engaged with the upper clamping block 18. The vertical portion of the azimuth locking handle 21 also slidably engages with the lower clamping block 19. The opposing surfaces of the upper clamping block 18 and the lower clamping block 19 are provided with arc-shaped platforms that mate with the edge of the turntable 6. After the azimuth angle is adjusted, rotating the azimuth locking handle causes the lower and upper clamping blocks to move closer together, clamping the edge of the turntable and achieving relative fixation between the housing and the turntable, further improving the structural stability.

[0035] Further optimize the above structure, such as Figure 2 As shown, the side walls and bottom outer surfaces of the housing 20 are respectively provided with scales 29 for displaying pitch and azimuth angles. The scales allow for a more intuitive observation of changes in pitch and azimuth angles.

[0036] In actual manufacturing, the support module 1 is a support column or a tripod.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
