Abstract
The utility model discloses an automatic revolving globe with adjustable speed, including a base, a ball, a power, an electric motor, a speed regulator and an adjusting knob. The electric motor is a DC reducing motor provided with the speed regulator, thus able to achieve stepless speed regulation of the rotating speed of the motor. The ball is a solid or hollow ball with two opposite fixing rings on the south and the north poles arranged on a central axis. The central axis and the fixing rings are matched closely with one end penetrating the ball bearing on the base and extending to the deep slot of the connecting piece on the upper end of the motor shaft, so as to guarantee the fixed joint between the end and the slot. The ball bearing is corresponding to the connecting piece on the upper end of the motor shaft so as to make an included angle between the central axis and the horizontal of 22.1-24.5 degrees. The adjusting knob is controlled to make the globe revolve according to the rotating speed required by the observer. The utility model has the advantages of simple structure, convenient operation and revolving according to the rotating speed required by the observer.
