Abstract

The invention discloses an environmental protection propaganda board facilitating propaganda paper replacement. The environmental protection propaganda board comprises two main support plates and secondary support plates, the bottom ends of the main support plates and the bottom ends of the secondary support plates are welded to form two bearing frames, a cavity is formed between each main supportplate and the corresponding secondary support plate, a transmission assembly is arranged at the top ends of the two bearing frames, and a cover plate and a carrier plate are welded between the upperends and the lower ends of two bearing frames respectively. A transmission rod and a roller screw rod are electrically driven to rotate in situ, a display board is driven to move vertically with upright rods as the fulcrums through transmission between the roller screw rod and a roller nut, the display board also moves in the limited range of the bearing frames, sealed protection can be conveniently performed on the display board and propaganda paper through tempered glass, by rapidly clamping and fixing the propaganda paper on the display board, rapid detachment and installation are realized,direct contact with the outside is reduced, the installation stability of the propaganda paper is easily guranateed, then the service life of the propaganda paper is prolonged, and the propaganda board can be repeatedly used.
