Linkage locking mechanism and downward inclination angle control device of antenna

Abstract

The invention discloses a linkage locking mechanism and a downward inclination angle control device of an antenna. The linkage locking mechanism comprises an installation rack, output assemblies and arotation support, wherein installation positions are arranged on the installation rack, installation through holes and clamping bodies are arranged at the installation positions, each output assemblycomprises an output shaft and an output gear, the output gear is arranged on the output shaft in an elastic reset way, a buckle body and a prop-against body are arranged at one end of the output gear, the buckle body is buckled with the clamping body, the prop-against body is arranged in a way penetrating the installation through hole, the rotation support is provided with a pressure-bearing surface and arc bosses, the pressure-bearing surface props against the prop-against body, each arc boss is arranged on the pressure-bearing surface and comprises a guide end, an inversion-prevention end and a matching body, when the prop-against body of one of the output gears props against the matching body of one of the arc boss in a matching way, the other output gears are locked, and the prop-against body of at least one output gear is matched with the inversion-prevention end of one of the arc boss in an inversion-prevention way. The linkage locking mechanism and the downward inclination angle control device of the antenna are convenient to position, and accurate control on a downward inclination angle of the antenna can be achieved.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a linkage locking mechanism and an antenna downtilt angle control device. Background technique [0002] With the increasing number of mobile communication terminal users, the demand for network capacity of sites in the mobile cellular network is increasing. At the same time, it is required to minimize the interference between different sites or even between different sectors of the same site, that is, to realize the network Maximize capacity and minimize interference. To achieve this goal, it is usually implemented by driving the downtilt angle of the antenna beam on the station. [0003] At present, the ways to drive beam downtilt are divided into: mechanical downtilt and electronic downtilt, and electronic downtilt has obvious advantages, which is the current mainstream and future development trend. The structure of the traditional electronic downtilt t...

Problems solved by technology

The structure of the traditional electronic downtilt transmission device is relatively complicated, and the positioning function is insufficient at the same time, so it is impossible to achieve more precise control
