Windproof advertising board base

Abstract

The invention provides a windproof billboard base, which belongs to the technical field of billboards. When installing, first put the deep groove ball bearing into the bearing seat and lock it through the bearing pressure ring, insert the rotating shaft into the inner ring of the bearing, and install the locking flange from the bottom of the base, and then pull it out from the coil spring box Coil spring, insert the right-angle plug of the coil spring into the spring channel of the coil spring driven shaft, and lock it through the coil spring pressing block. When using, first loosen the locking screw on the chuck, and then hold the push The handle on the rod rotates along the arc groove. Under the pulling force of the flat scroll spring, the rotating shaft will follow the push rod to rotate to realize the rotation of the billboard. When encountering strong wind, the windward side of the billboard will Angle deflection occurs along the direction of the wind to achieve the purpose of reducing the force. When the wind becomes smaller, under the tension of the flat scroll spring, the vertical billboard will return to its original position, so that The automatic adjustment of the position is realized.
