As shown in fig. 3, the transmission mechanism 10 includes a mount 100; the transmission assembly 200 includes a screw 210 rotatably disposed on the mounting base 100, a nut member 220 in screw transmission engagement with the screw 210, and a rotating member 230 rotatably disposed on the mounting base 100, the screw 210 can drive the nut member 220 to move along an axial direction of the screw 210, a transmission structure (not shown) is disposed between the nut member 220 and the rotating member 230, the nut member 220 can drive the rotating member 230 to rotate through the transmission structure, and the rotating member 230 is provided with a first connection portion 232 fixedly connected to the antenna body 20.
As shown in fig. 1 to fig. 3, when the transmission mechanism 10 is applied to adjust the horizontal azimuth angle of an antenna, the screw 210 can be driven to rotate manually or by using an electric driving mechanism, and the nut member 220 is driven to move, and the nut member 220 can drive the rotating member 230 to rotate through the transmission mechanism, so as to drive the antenna body 20 to rotate, thereby adjusting the horizontal azimuth angle; in this process, since the transmission ratio between the screw rod 210 and the nut member 220 can be selected, the rotation angle of the nut member 220 driving the rotation member 230 to rotate can be calculated by rotating the rotation angle of the screw rod 210, and the adjustment of the angle of the antenna in the horizontal direction can be known. This drive mechanism 10 can avoid the error of subjective judgement when artifical the regulation, ensures the construction team in the installation engineering of antenna, the accuse of the horizontal azimuth accuracy of antenna, improves communication quality.
Specifically, the electrically controlled driving mechanism or the manual rotating mechanism inputs a rotational motion and a torque to drive the screw 210 to rotate, since the screw 210 and the nut member 220 have a mechanical screw transmission function; when the screw rod 210 rotates by a certain angle γ, the nut member 220 simultaneously moves linearly by a certain distance L, and the linear movement distance L of the nut member 220 simultaneously drives the rotating member 230 to rotate by an angle ω through the transmission structure, so that the antenna can rotate along with the rotation of the screw rod 210, and the precise adjustment of the square angle can be completed when the horizontal position of the antenna reaches a preselected position.
The electric drive mechanism may be a servo motor 30, a rotary hydraulic cylinder, or other conventional rotary power device.
On the basis of the above embodiment, the transmission structure includes a slide rail (not labeled) and a slide block (not labeled) in sliding fit with the slide rail, and the moving track of the slide block and the moving track of the nut member 220 are in a staggered state; the slide rail is disposed on the rotation member 230, and the slider is disposed on the nut member 220. Thus, the linear motion of the nut member 220 can be converted into the rotational motion of the rotary member 230 by using the slider-rocker principle; meanwhile, the power conversion is carried out by utilizing the sliding rail mechanism, so that the power conversion precision can be improved, and the combined installation is convenient.
Specifically, when the screw 210 rotates, the push nut member 220 moves linearly; the outer side wall of the nut member 220 can be directly or indirectly provided with a sliding block, so that the sliding block is driven to do linear motion along the length direction of the sliding rail; at this time, since the moving track of the sliding block and the moving track of the nut member 220 are in a staggered state, and the sliding block is in sliding fit with the sliding rail, the sliding rail is fixed on the rotating member 230, and the rotating member 230 can rotate, so that the sliding block pushes the rotating member 230 to move during the moving process. In this way, the rotation of the antenna can be controlled, and the horizontal azimuth angle of the antenna can be adjusted.
Similarly, the transmission structure includes a sliding rail and a sliding block slidably engaged with the sliding rail, the moving track of the sliding block and the moving track of the nut member 220 are in a staggered state, the sliding rail is disposed on the nut member 220, and the sliding block is disposed on the rotating member 230. Therefore, the linear motion of the nut member 220 can be converted into the rotational motion of the rotating member 230, and the detailed motion process can refer to the description of the previous embodiment and will not be described herein.
As shown in fig. 3 to fig. 5, in the embodiment, the transmission structure includes a first sliding groove 234 opened on the rotating member 230 and a first matching element 222 disposed on the nut member 220, the first matching element 222 is slidably matched with the first sliding groove 234, and a moving track of the first matching element 222 and a moving track of the nut member 220 are in a staggered state. Thus, the first sliding groove 234 is engaged with the first mating member 222, and the linear motion of the nut member 220 is converted into the rotational motion of the rotating member 230 according to the slider-rocker principle.
Specifically, when the screw 210 rotates, the push nut member 220 moves linearly; the outer side wall of the nut member 220 can directly or indirectly form the first mating member 222, so as to drive the first sliding block to move linearly along the length direction of the first sliding groove 234; at this time, since the moving track of the first mating element 222 and the moving track of the nut element 220 are in a staggered state, the first mating element 222 is in a pressing sliding fit with the first sliding groove 234, the first sliding groove 234 is opened on the rotating element 230, and the rotating element 230 can rotate, so that the rotating element 230 is pushed to move by the first mating element 222 in the moving process. In this way, the rotation of the antenna can be controlled, and the horizontal azimuth angle of the antenna can be adjusted. Meanwhile, the first sliding slot 234 and the first mating member 222 can limit the rotation angle of the rotating member 230, so as to set the start point and the end point of the rotation of the rotating member 230, which is beneficial to writing a control program.

Thus, the driven member 400 is used to unload the weight of the antenna body 20 and the external force caused by the wind load, and the driven member 420 only bears the rolling friction force and a small part of the torque, so that the reliability and the accuracy of the horizontal direction adjustment of the antenna body 20 can be improved.
The mounting base 100 may be integrally formed or may be formed by fixedly connecting a plurality of base bodies. In this embodiment, the mounting base 100 includes a first base 102 for mounting the screw 210 and the nut 220, a second base 104 for connecting the rotating member 230, and a third base 106 fixed on the fixing bracket 300, wherein the first base 102 and the second base 104 are fixed on the third base 106.
