DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0020] Specific implementation examples Figure 1-4 As shown, an antenna attitude adjustment device includes an upper bracket 3 and an upper bracket 4 respectively connected to the upper and lower ends of the antenna 2, and the upper bracket 3 and the lower bracket 4 are respectively connected to the fixed rod 1. The key is that the upper bracket 3 and the lower bracket 4 are respectively connected to the fixed rod 1 by means of a swinging assembly. The swinging assembly includes a connecting block 5, a telescopic cylinder 6 and a cantilever seat 9. The fixed end of the cantilever seat 9 is fixedly connected to the fixed rod 1, and the connecting block 5 is hinged to the cantilever end of the cantilever seat 9. The connecting block 5 is respectively connected to the upper bracket 3 and the lower bracket 4, and the telescopic cylinder 6 is arranged between the connecting block 5 and the cantilever seat 9. The connecting block 5 has the freedom to swing around the z-axis at the cantilever end of the cantilever seat 9 by means of the extension and contraction of the telescopic cylinder 6, that is, the antenna 2 has the freedom to adjust the azimuth angle by means of the extension and contraction of the telescopic cylinder 6.
[0021] In this embodiment, the installation of the telescopic cylinder 6 can be achieved by simply adding mounting holes for the telescopic cylinder 6 on the connecting block 5 and the overhanging seat 9; the z-axis is located on the center line of the connecting block 5, and the telescopic cylinder 6 is located on one side of the z-axis and hinged to the side of the connecting block 5. The length of the telescopic cylinder 6 changes, and the one side of the connecting block 5 is pulled or pushed. The connecting block 5 drives the antenna 2, the upper bracket 3, and the lower bracket 4 to rotate along the z-axis to adjust the azimuth angle of the antenna. The telescopic cylinder 6 is an electric telescopic cylinder. The components used for azimuth angle adjustment in this embodiment are simple in structure and easy to install. The changes to the original connectors are minor, and there is no need to add too many components, saving improvement costs.
[0022] The upper bracket 3 includes a fixing frame 30, a first bracket 31 and a second bracket 32 which are hinged to each other in sequence. The fixing frame 30 is connected to the antenna 2. The second bracket 32 and the lower bracket 4 are respectively hinged to the connecting block 5. With the help of the upper bracket 3 and the lower bracket 4, the antenna 2 has the freedom to swing around the y-axis on the connecting seat 5, that is, the antenna 2 has the freedom to adjust the pitch angle with the help of the upper bracket 3 and the lower bracket 4.
[0023] The hinged end 33 where the first and second brackets 31 and 32 are hingedly connected is further provided with a first guide arc plate 35 and a second guide arc plate 36, respectively, each with a guide slot 34. The guide slot 34 is coaxial with the hinge axis of the hinged end 33. The first and second brackets 31 and 32 are fixedly connected by a bolt assembly passing through the guide slot 34. The first and second guide arc plates 35 and 36 with guide slots 34 guide the adjustment of the pitch angle of the antenna 2, preventing the antenna 2 from twisting and improving the accuracy of angle adjustment. Furthermore, the combination of the bolt assembly and the first and second guide arc plates 35 and 36 effectively reduces the stress on the hinge axis of the hinged end 33, preventing deformation of the hinge axis and improving the connection strength and stability of the hinged end 33.
[0024] The first guide arc plate 35 is arranged on the first bracket 31, and the second guide arc plate 36 is arranged on the second bracket 32. The first guide arc plate 35 and the second guide arc plate 36 are respectively located on the outside of the upper bracket 3, which is convenient for installation. At the same time, the force at the hinge end 33 is evenly distributed to the first bracket 31 and the second bracket 32, further improving the connection stability and connection strength.
[0025] The bolt assembly includes a fixing bolt 7 and a nut 8. The fixing bolt 7 is respectively arranged on the first bracket 31 and the second bracket 32 and passes through the guide groove 34. The nut 8 is respectively located on the outside of the first guide arc plate 35 and the second guide arc plate 36 and is matched with the fixing bolt 7. By loosening the nut 8 on the fixing bolt 7, the first bracket 31 and the second bracket 32 can be made into a movable connection. By swinging the first bracket 31 and the second bracket 32, the pitch angle of the antenna 2 can be adjusted. After the adjustment is completed, the two nuts 8 are tightened to complete the fixation of the first bracket 31 and the second bracket 32, thereby fixing the pitch angle of the antenna 2.
[0026] The upper and lower ends of the antenna 2 are respectively connected to the connecting block 5 and the overhanging seat 9. Preferably, the telescopic cylinder 6 is connected to the connecting block 5 and the overhanging seat 9 located at the lower end of the antenna 2, thereby optimizing the overall layout of the adjustment device, reducing the length of the wires connected to the telescopic cylinder 6, and reducing the setting cost and difficulty.
[0027] The utility model relates to an antenna attitude adjustment device, which can achieve mechanized adjustment and control of the azimuth angle by simply adding a telescopic cylinder 6, eliminating the need for manual adjustment; the connection strength at the hinge end 33 of the first bracket 31 and the second bracket 32 is enhanced, so that the force between the first bracket 31 and the second bracket 32 is more uniform; the structural layout of the overall device is optimized, with minimal changes to the original adjustment device and low production cost.
