[0023] 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.

[0024] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an adjustable base station antenna, comprising a fixed column 1, a sliding column 2 is slidably connected inside the fixed column 1, a fixed block 3 is fixedly connected to one side of the outer wall of the sliding column 2, a motor 4 is fixedly connected inside the fixed block 3, a connecting block 5 is fixedly connected to the output end of the motor 4, a fixed rod 6 is rotatably connected inside the connecting block 5, a fixed ring 10 is fixedly connected to the outer wall of the fixed rod 6, a connecting rod 11 is fixedly connected to the inner wall of the fixed ring 10, a pulley 12 is arranged on one side of the outer wall of the connecting rod 11, a fixed ring 2 13 is slidably connected to the outer wall of the pulley 12, a connecting frame 7 is fixedly connected to the outer wall of the connecting frame 7, a hinge seat 8 is rotatably connected to one side of the outer wall of the hinge seat 8, a radiation element 9 is fixedly connected to one side of the outer wall of the sliding column 2, a hydraulic rod 15 is fixedly connected to one side of the outer wall of the sliding column 2, and the output end of the hydraulic rod 15 is fixedly connected to one side of the outer wall of the fixing ring 2 13, an adjusting component is arranged inside the fixed column 1, and the adjusting component is used to adjust the height of the sliding column 2.

[0025] Specifically, when the radiation element 9 needs to adjust its position to optimize the signal coverage, the motor 14 drives the connection block 5 to rotate, so that the fixed rod 6 rotates accordingly, the hydraulic rod 15 pushes the fixed ring 2 13 to move, the connection rod 11 fixedly connected to the fixed ring 10 rotates together with the fixed rod 6, and the pulley 12 slides inside the groove 14, so that the radiation element 9 can adjust the vertical angle and flexibly optimize its signal direction. This adjustment method is more flexible and accurate, and can meet the needs of base station antennas.

[0026] Reference Figure 2 and Figure 3The adjusting component includes a motor 2 16, which is fixedly connected to one side of the outer wall of the sliding column 2, and a connecting rod 2 17 is fixedly connected to the output end of the motor 2 16. The inner wall of the fixed column 1 is fixedly connected to a limit block 18, and the outer wall of the connecting rod 2 17 is rotatably connected to the inside of the limit block 18. A threaded rod 21 is rotatably connected inside the fixed column 1, and a worm gear 20 is fixedly connected to the outer wall of the threaded rod 21. A worm 19 is fixedly connected to one end of the connecting rod 21, and the worm 19 is meshed with the worm gear 20. A connecting frame 22 is threadedly connected to the outer wall of the threaded rod 21, and a sliding rod 23 is slidably connected to the inside of the threaded rod 21. The outer wall of the sliding rod 23 is fixedly connected to the inside of the connecting frame 22. A groove 14 is opened inside the fixing ring 2 13, and the outer wall of the pulley 12 is rotatably connected to the inner wall of the groove 14.

[0027] Specifically, the motor 16 drives the connecting rod 17 to rotate the inside of the limit block 18, and the worm 19 engages with the worm wheel 20, thereby driving the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the connecting frame 22 to move thereon, and then the sliding rod 23 moves up and down inside the threaded rod 21, realizing the lifting and lowering of the sliding column 2 to adjust the height of the device, facilitate the staff to repair the base station antenna, and reduce the danger of high-altitude maintenance operations.

[0028] Working principle: When the adjustable base station antenna is needed, the motor 2 16 drives the connecting rod 2 17 to rotate inside the limit block 18, so that the worm 19 engages the worm wheel 20 to rotate the threaded rod 21, and the threaded rod 21 rotates to make the connecting frame 22 move on the threaded rod 21, and then the connecting frame 22 drives the sliding rod 23 to slide inside the threaded rod 21, so that the sliding rod 23 drives the sliding column 2 to rise and fall to change the height. The motor 2 16 is installed on the outside of the fixed column 1 for easy heat dissipation and maintenance, which improves the convenience of using the device. When the radiation element 9 needs to adjust its position to optimize the signal coverage range, The motor 14 drives the connecting block 5 to rotate, so that the fixing rod 6 rotates under the drive of the connecting block 5, so that the radiation element 9 can rotate, and then the fixing ring 13 is driven to move by the hydraulic rod 15, so that the connecting rod 11 and the fixing ring 10 connected by the groove 14 rotate on the outer wall of the fixing rod 6, and the fixing ring 10 is fixedly connected to the fixing rod 6. Therefore, when the pulley 12 slides inside the groove 14, the radiation element 9 can adjust the vertical angle, so as to achieve the effect of flexibly adjusting the direction of the radiation element 9. Compared with the hinge connection adjustment, this adjustment method is more flexible and can better meet the needs of the radiation element 9 to optimize the signal.
