[0002] An antenna is a device used to receive and send electromagnetic waves, and is usually used in wireless communications, radio, television and other equipment. Antennas are usually made of conductive materials, and their length and shape can affect the effectiveness of their reception and transmission of signals. Antennas can help devices receive signals from long distances, making communications more stable and effective. Common types of antennas include antenna rods, frequency converters, antenna arrays, etc. In the prior art, when antennas are used outdoors, a fixing device is required. However, since the signal reception is not fixed, most of the existing fixing devices have an elevation adjustment function. When the signal reception is poor, angle adjustment is required. The current elevation adjustment is mostly fixed by tightening the bolts at intervals. The angle adjustment gear intervals are large, the signal reception effect is poor, and the elevation adjustment structure itself is large, not convenient to carry, and cannot meet the use requirements. Therefore, the inventor proposes an antenna elevation adjustment device. Utility Model Content

[0023] This specific implementation is an antenna elevation control device, and its structural schematic diagram is as follows Figure 1 , Figure 2 As shown, it includes a support base plate 1, a vertical pole 2, a lifting rod 6 and an adjustment column 3. The support base plate 1 is arranged at the bottom of the vertical pole 2. The vertical pole 2 is vertically arranged with an adjustment column 3 slidably installed on the top. The lifting rod 6 is slidably installed on the top of the adjustment column 3. A rotating shaft 10 is rotated through the upper end of the lifting rod 6. Rotating rods 8 are fixed at both ends of the rotating shaft 10. The rotating rod 8 is coaxially distributed with the rotating shaft 10. A connecting block 7 is fixedly installed on the upper surface of the rotating rod 8. The part of the rotating shaft 10 located inside the lifting rod 6 is sleeved with a driving gear 9. A driving block 11 is arranged below the driving gear 9. The upper surface of the driving block 11 has a tooth block. The driving block 11 is adapted to the driving gear 9. The end of the driving block 11 is fixedly connected to a slider 12. The end of the slider 12 away from the driving block 11 is rotatably connected to the adjustment shaft 4. A fixing pipe 5 is fixed on the outer wall of the lifting rod 6. The fixing pipe 5 is threadedly connected to the adjustment shaft 4.

[0024] Reference Figure 3 , Figure 4, the adjusting column 3 is symmetrically distributed on both sides of the lifting rod 6, and the adjusting column 3 is fixedly connected to the lifting rod 6. The end of the adjusting column 3 away from the lifting rod 6 is slidably connected with a jacket block 13, and the jacket block 13 is fixedly connected to the outer wall of the vertical rod 2. The jacket blocks 13 are symmetrically distributed on the two side walls of the vertical rod 2, and a fixed column 16 is fixed between the jacket blocks 13 on both sides of the same side, and a limited plug rod 14 is slidably installed inside the fixed column 16. The limited plug rod 14 is an L-shaped structure, and one end slides inside the fixed column 16, and the other end extends through the fixed column 16. A sliding groove for the limited plug rod 14 to pass through is horizontally opened in the middle of the fixed column 16. Two groups of limited plug rods 14 are symmetrically arranged inside the fixed column 16, and a spring 15 is connected between the two groups of limited plug rods 14.

[0025] Working principle: When in use, first move the support base plate 1 to the antenna installation position, then connect the antenna to the connecting block 7. At this time, according to the signal reception requirements of the antenna, rotate the adjustment shaft 4, and screw the adjustment shaft 4 along the fixed tube 5 thread, pushing the slider 12 and the inside of the fixed tube 5 to slide toward the inside of the lifting rod 6. At this time, the driving block 11 slides under force, and the driving block 11 contacts the driving gear 9. The driving gear 9 is rotated under force, driving the rotating shaft 10 to rotate, and the antenna fixedly connected to the rotating shaft 10 is forced to rotate synchronously. According to the elevation adjustment requirements of the antenna, the adjusting shaft 4 is rotated forward or reversed;

[0026] Before the antenna and the connecting block 7 are fixedly installed, the height of the antenna can be raised by adjusting the column 3, and the two sets of limit rods can be pulled toward opposite positions.
