Abstract

The invention discloses a teaching device for the major of business management. The teaching device comprises a frame, wherein a top box is arranged at the top of the frame; an upper blackboard is arranged at the upper position between the left and right sides of the frame; a lower blackboard is arranged at the lower position between the left and right sides of the frame; pulleys are arranged respectively at the positions, at the tops of the upper blackboard and the lower blackboard, near the left and right sides; pull ropes are arranged between the pulleys; fixed blocks are arranged at the back of the frame; and expansion bolts are arranged in the fixed blocks. In the teaching device, the rotation of rope wheels on transmission shafts is controlled through a stepper motor I and a steppermotor II; and the rope wheels drive lifting ropes to wind and unwind, so that the upper blackboard and the lower blackboard can move past each other freely in the vertical direction, thereby avoidingthe problem that the height of the traditional blackboard cannot be set too high, which results in limited area at writing for teaching and frequent erasure, thus affecting the teaching consistency ofteachers as well as students' combination, application and understanding of knowledge learned earlier and later. Therefore, the teaching device greatly improves the quality of teaching.
