Abstract

The invention discloses a regulating device for a rotating scale of a tunable antenna. The regulating device comprises a threaded rod, a drive rod, a drive slide block, a check block, a support block and a gear drive mechanism, wherein the device is mounted on a fixing plate in the antenna, the threaded rod and the drive rod are axially parallel, the drive slide block is connected with the threaded rod and the drive rod through a screw mechanism, the check block is fixed on the threaded rod and keeps synchronous rotation with the threaded rod, a support piece supports the threaded rod and the drive rod at the two ends, and the gear drive mechanism is sleeved with the threaded rod, keeps axially concentric with the threaded rod, and drives a scale ring to rotate through gear mesh drive, so as to indicate the electric downtilt of the antenna. According to the regulating device for the rotating scale of the tunable antenna, the scale of the antenna is changed from linear stretching to circumferential rotating, so that the risk of clamping a linear scale is avoided, the spaces of an end face and a plane of the antenna are saved, the structure is compact, and the functions of regulating the electric downtilt and indicating the angle of the tunable antenna are realized.

Description

technical field [0001] The present invention relates to the technical field of electronically adjustable antennas, in particular to a mechanical structure for adjusting the downtilt angle of the electronically adjustable antenna, in particular to a mechanical structure with a high-precision angle rotating scale capable of adjusting the downtilt angle of the electrically adjustable antenna. [0002] Background technique [0003] The so-called electronically adjustable antenna refers to a mobile antenna that electronically adjusts the downtilt angle. The application of electronically adjustable antennas in mobile communications is becoming more and more popular. Existing electronically adjustable antennas are generally equipped with an electrical downtilt adjustment structure. The electrical downtilt angle of the electronically adjustable antenna is adjusted by adjusting the phase shifter inside the antenna. The ruler shows the downtilt angle of the antenna. [0004] At pres...
