Screen projection type intelligent education blackboard for drawing training

Abstract

A screen projection type intelligent education blackboard for drawing training is disclosed. A storage box is clamped to the lower side of the front end of a drawing board, side panels are fixed to the left side and the right side of the upper end of the drawing board, dip angle groove holes are formed in the side panels, back plates are rotationally connected into the dip angle groove holes, the dip angle groove holes are rotationally connected with the back plates through bolts, the bolts are provided with nuts, the upper sides of the nuts are clamped in zigzag grooves of the dip angle groove holes, and side plates are fixed to the left and right sides of the back plates. Through the drawing board and the back plates which can be accommodated, supporting legs are stored together, the occupied space is reduced; multimedia teaching can be carried out through a display board which can be stored, thus meeting the increasingly abundant teaching requirements. The position of the gravity center of a projector can be adjusted through a propeller strut and a stay wire, the positive and negative of the pressure can be judged through numbers on the projector, when the pressure is close to zero, it is indicated that the gravity center falls on the display board, and the stability of the display board is improved.

Description

technical field [0001] The invention relates to the field of painting training, in particular to a screen-projecting smart education blackboard for painting training.
