Abstract
A linked locking mechanism and antenna down-tilt angle control device is described. Linked locking mechanism includes: mounting frame with a mounting positions, each mounting position has a mounting through hole and a clamping body. Output assembly includes an output shaft and output gear resiliently disposed on output shaft. One end of output gear has engaging body engaged with clamping body and pressing body provided through mounting through hole. Rotating bracket has pressure bearing surface pressed against pressing body. Arc-shaped embossments are provided on pressure bearing surface. The arc-shaped embossment includes guide end, anti-reverse end, and mating body. When mating body and pressing body abut, and engaging body and clamping body are separated, output gear drives output shaft to rotate. Linked locking mechanism and antenna down-tilt angle control device provide easy positioning and accurate control of down-tilt angle of antenna.
