Abstract
The utility model relates to a novel blackboard, which belongs to the teaching tool. The blackboard is made to have adjustable angles of two sides, and to eliminate the reflecting of the students sitting on the side edge of the classroom. The utility model comprises a left blackboard, a middle blackboard, and a right blackboard which are connected as a whole. The utility model is characterized in that a left hinge is arranged between the left blackboard and the middle blackboard, and a right hinge is arranged between the right blackboard and the middle black board. The blackboard in the existing classroom is already fixed, and the safety of the students after the class is affected if the left blackboard and right blackboard are folded outward. The two sides of the utility model are movable, can be pulled out during the class, and can be pushed back after the class. The design of the utility model is scientific, and the utility model is safe, convenient, and practical, and the effect is very good.
Description
One, technical field
The utility model relates to a kind of new type blackboard, relates in particular to a kind of a kind of new type blackboard of blackboard being made the both sides changeable angle.
