<p>An adjusting device for phase shifter of antenna in mobile communication is provided. The adjusting device comprises a gear, a rack, a screw, a driving nut, a driving shaft, and a manipulating member. The gear is dead jointed to the rotation axis of the phase shifter mounted on the reflecting plate of the antenna, and the rack is dead jointed to the driving shaft. One end of the driving nut is dead jointed to the driving shaft, there is a screw hole in the other end of the nut, and the nut is coupled to the screw via the screw hole. One end of the manipulating member is dead jointed to the screw, and the driving shaft and the screw are respectively supported by a driving shaft supporter and a screw supporter which are mounted on the reflecting plate of the antenna. Further, the adjusting device may be connected with an external control device having a rotation axis. There is a hole in the other end of the manipulating member, the hole is coupled to the rotation axis of the control device, and the manipulating member may be controlled via the rotation axis of the control device to implement the adjustment. The invention need not modify the internal structure of the external control device for different mechanical route of the phase shifter. Thus, the invention has an approved versatility, and can adjust the down tilt more accurately.</p> |
