Road signboard

The invention relates to the technical field of signboards, in particular to a road signboard which comprises a circular fixing frame and a supporting column, the inner wall of the circular fixing frame is in threaded connection with a fixing cylinder, the inner wall of the fixing cylinder is fixedly connected with a filling block, and cavities distributed at equal intervals are formed in the filling block; the filling block is slidably connected with a circular sliding block through the inner wall of the cavity, and the upper surface of the filling block is fixedly connected with a supporting disc. Through the arrangement of the supporting column, the supporting tray, the steel wire rope, the circular sliding block, the supporting spring and other components, the steel wire rope component can compress the supporting spring through the circular sliding block through the mutual matching relation between the supporting tray component and the steel wire rope component; and therefore, the effect that the impact f
