Abstract

The invention discloses a simply demountable type movable blackboard device. The simply demountable type movable blackboard device comprises a blackboard body. A first rotating shaft and a second rotating shaft are fixed on the left side and the right side of the middle of the blackboard body. Two supporting legs are located on two sides of the blackboard body. The middles of the two supporting legs are provided with through holes, self-lubricating sleeves are inserted in the through holes, and the outer side walls of the self-lubricating sleeves are fixed to the inner side walls of the through holes. The first rotating shaft and the second rotating shaft are inserted in the corresponding self-lubricating sleeves. The end of the first rotating shaft is a spline shaft portion, and a servo adjusting motor fixing frame is fixed to the supporting leg corresponding to the first rotating shaft. A servo adjusting motor is fixed to the servo adjusting motor fixing frame. A spline hole is formed in the end of an output shaft of the servo adjusting motor. The end of the first rotating shaft is inserted into the spline hole. Two connecting rods are fixed in front of the two supporting legs. All components of the simply demountable type movable blackboard device are convenient to demount, and thus carrying and installation are convenient. Meanwhile, automatic angle adjustment of the blackboard body can be achieved, so that user requirements are met.

Description
