Abstract
The invention provides a portable antenna pitching angle positioning and locking mechanism, and belongs to the technical field of antenna equipment. The device comprises a pitching rotating shaft, a rotary table support lug, a first telescopic rod, a second telescopic rod and a locking nut. A first eccentric shaft is fixedly arranged at the tail end of the pitching rotating shaft in the axial direction. The rotary table support lug is provided with a kidney-shaped groove penetrating through the end faces of the two sides of the rotary table support lug, and a second eccentric shaft is fixedly arranged on the rear end face of the rotary table support lug in the axial direction. The kidney-shaped groove and the second eccentric shaft are close to the edges of two opposite sides on the end face of the rotary table supporting lug respectively. Compared with the prior art, the manual portable antenna pitching angle positioning and locking mechanism is low in cost and simple and easy to operate, pitching angle locking and positioning can be completed only by rotating a hand wheel, the manual portable antenna pitching angle positioning and locking mechanism is safe and reliable, and the phenomenon of loosening under the action of wind loads after locking is avoided.
Description
Technical field [0001] The present invention belongs to the technical field of antenna equipment, and more particularly to a portable antenna pitch angle locking device. Background technique [0002] During the work of the portable antenna, the stability of the antenna system is a prerequisite for the antenna system. Among them, especially the lock of the antenna surface is the most critical. [0003] In the locking device design of the portable antenna, it is necessary to meet high reliability and simple operation, and existing multi-frequency feedforward, fed manual portable antenna antenna surface pitch angle lock positioning, current market multi-frequency hand-portable antenna The pitch angle lock positioning means is high of a worm wheel self-locking device, and the shelter is unstable with the frictional self-locking structure. Inventive content [0004] To this end, the object of the present invention is to provide a portable antenna pitch angle locking device to overcom...
