[0036] An antenna is an electrical device used for transmitting or receiving radio waves, and is a key component in a wireless communication system. The higher the working frequency of the antenna, the more sensitive it is to changes in angle. The related adjustment mechanism cannot accurately adjust the angle of the antenna, and cannot be self-locked after adjustment, which is easy to deviate and has low adjustment accuracy, which brings many inconveniences to the user and affects the use experience and effect. There are also some antenna angle adjustment mechanisms on the market that can support angle fine adjustment, which usually include a worm gear structure and a motor, and often have complex structure and high cost.
[0037] An antenna adjustment device is provided in the embodiments of the present application, Figure 1 A structural schematic diagram of an antenna adjustment device according to an embodiment of the present application, Figure 2 A structural schematic diagram of an antenna adjustment device according to an embodiment of the present application, Figure 3 A structural schematic diagram of an antenna adjustment device according to an embodiment of the present application, Figure 2 A sectional view at A-A. Please refer to Figures 1 to 3 The adjustment device includes an antenna hanger 100, a first rotating shaft 230, a second rotating shaft 330, a first adjustment mechanism 200, and a second adjustment mechanism 300. The antenna hanger 100 is used for detachable connection with the antenna, the antenna hanger 100 is fixedly connected with the first rotating shaft 230 and can rotate around the first rotating shaft 230, and the antenna hanger 100 is fixedly connected with the second rotating shaft 330 and can rotate around the second rotating shaft 330. The first adjustment mechanism 200 includes a first bolt 210 and a first transmission assembly 220 connected with the first bolt 210, and the first transmission assembly 220 is connected with the antenna hanger 100, so that the first bolt 210 can drive the antenna hanger 100 to rotate around the first rotating shaft 230 through the first transmission assembly 220. The second adjustment mechanism 300 includes a second bolt 310 and a second transmission assembly 320 connected with the second bolt 310, and the second transmission assembly 320 is connected with the antenna hanger 100, so that the second bolt 310 can drive the antenna hanger 100 to rotate around the second rotating shaft 330 through the second transmission assembly 320. The axis of the first rotating shaft 230 and the axis of the second rotating shaft 330 are perpendicular to each other.
[0038] When the adjustment device is in an upright state, the axial direction of the first rotating shaft 230 is horizontal, and the first adjustment mechanism 200 is used for adjusting the pitch angle of the antenna 10; the axial direction of the second rotating shaft 330 is vertical, and the second adjustment mechanism 300 is used for adjusting the horizontal angle of the antenna 10.
[0039] In some optional embodiments, the adjusting device comprises a first hanger 400 for connecting with a support structure such as a wall, a jib, etc. One end of the first rotating shaft 230 is fixedly connected with the antenna hanger 100, and the other end of the first rotating shaft 230 is rotatably connected with the first hanger 400. The first screw 210 can drive the antenna hanger 100 to rotate around the first rotating shaft 230 relative to the first hanger 400 through the first transmission assembly 220.

[0041] With reference to Figures 1 to 3 The first transmission assembly 220 comprises a first sliding slot 221 and a first slider 222 arranged in the first sliding slot 221. The first sliding slot 221 is arranged on the first hanger 400, and the first slider 222 is threadedly connected with the first screw 210, so that the first screw 210 drives the first slider 222 to move in the first sliding slot 221 only along the axial direction of the first screw 210. One end of the first rotating shaft 230 is rotatably connected with the first hanger 400, and the other end of the first rotating shaft 230 is fixedly connected with the antenna hanger 100. The antenna hanger 100 is in transmission connection with the first slider 222. When the first screw 210 is rotated, the first slider 222 can move along the axial direction of the first screw 210 and cannot rotate along the axial direction under the limitation of the first sliding slot 221, and at the same time, the first slider 222 drives the antenna hanger 100 to rotate around the first rotating shaft 230. In the above adjusting process, because the first screw 210 and the first slider 222 are threadedly connected, they have a self-locking feature, so that the antenna hanger 100 can be suspended at any angle.
[0042] In some optional embodiments, the adjusting device comprises a second hanger 500 arranged between the antenna hanger 100 and the first hanger 400. The second hanger 500 is rotationally connected to the first hanger 400 through a first rotation shaft 230, specifically, one end of the first rotation shaft 230 is fixedly connected to the second hanger 500, and the other end of the first rotation shaft 230 is rotationally connected to the first hanger 400, and the second hanger 500 is fixedly connected to the antenna hanger 100 in a direction perpendicular to the first rotation shaft 230, so that the second hanger 500 can drive the antenna hanger 100 to rotate relative to the first hanger 400 around the first rotation shaft 230. Meanwhile, one end of a second rotation shaft 330 is fixedly connected to the antenna hanger 100, and the other end of the second rotation shaft 330 is rotationally connected to the second hanger 500, so that the antenna hanger 100 rotates relative to the second hanger 500 around the second rotation shaft 330.
[0043] It can be understood that the second transmission assembly 320 in the present application is used to convert the axial movement of the second bolt 310 into the rotation of the antenna hanger 100. The second transmission assembly 320 includes but is not limited to a slider slot assembly, a chain and sprocket assembly, a shaft coupling, a gear and a gear box, etc. Preferably, the second transmission assembly 320 is a slider slot assembly, which has a simple structure and low production and maintenance costs.

One end of the second rotation shaft 330 is rotationally connected to the second hanger 500, and the other end of the second rotation shaft 330 is fixedly connected to the antenna hanger 100, and the antenna hanger 100 is drivingly connected to the second sliding block 322. When the second bolt 310 is rotated, the second sliding block 322 can move in the axial direction of the second bolt 310 and cannot rotate in the axial direction under the limitation of the second sliding groove 321, and at the same time, the second sliding block 322 drives the antenna hanger 100 to rotate around the second rotation shaft 330. In the above adjusting process, because the second bolt 310 and the second sliding block 322 are threadedly connected, they have a self-locking feature, so that the antenna hanger 100 can be suspended at any angle.
[0045] In some optional embodiments, the first rotating shaft 230 is fixedly connected with the second hanger 500.
