The invention discloses an antenna direction regulating mechanism, which is connected to an antenna
assembly so as to erect the antenna
assembly on a fixed seat and regulate a direction of the antenna
assembly. The antenna direction regulating mechanism comprises an antenna assembly combination structure and a
pitch angle regulating structure, wherein the
pitch angle regulating structure comprises a
pitch angle regulating assembly, a bracket and a first
cam structure; the
pitch angle regulating assembly is provided with a first regulating type assembly groove; the first
cam structure is accommodated and limited between the first regulating assembly groove and the bracket, so locking assemblies are not needed at all when the first
cam structure is combined with the bracket; and when the first cam structure is driven to rotate, a first cam can drive the
pitch angle regulating assembly, the bracket and the antenna assembly combination structure to rotate in turn so as to regulate the direction of the antenna assembly.
