Description

A multifunctional music teaching blackboard

technical field

The utility model relates to teaching tools, in particular to a multifunctional music teaching blackboard.

Background technique

The blackboard is one of the necessary teaching aids in the teacher's teaching process. The blackboards in the prior art are all fixed on the wall, and the area of the blackboard is limited. It is obviously not enough for teachers with more writing on the blackboard. It is wasteful to wipe the blackboard during the teaching process. The valuable learning time of teachers and students is saved; projecting teaching content on the wall through a projector is a teaching method often used in the prior art, but in the prior art, the projector is mostly placed on the desktop, and the position of the projection is fixed and The size is difficult to control, so designing a multifunctional music teaching blackboard that can control the projection direction and projection size is an existing problem that needs to be solved urgently. .

Utility model content

The purpose of this utility model is to provide a kind of multifunctional music teaching blackboard aiming at the defects of the above-mentioned prior art. The utility model has the advantages of simple and reasonable structure and convenient use, and can effectively improve the efficiency and quality of classroom teaching.

The purpose of this utility model can be achieved through the following technical solutions: a multifunctional music teaching blackboard, including universal wheels, base, chute, roller, bracket, first push plate, second push plate, main board, projector, side support plate and piston rod;

The inside of the base is equipped with a chute, the upper end of the base is equipped with a bracket, the bracket is installed on the chute through the rollers at the bottom, the main board is installed on the bracket, and a side support plate is installed on one side of the bracket. A projector is installed on the side of the side support plate close to the bracket, a piston rod is installed on the lower end of the base, and a universal wheel is installed on the lower end of the piston rod.

Preferably, a first push plate and a second push plate are installed in the main board.

Preferably, the diameter of the enlarged window of the first push plate is smaller than the diameter of the enlarged window of the second push plate.

In the utility model, by adjusting the position of the main frame, projections at different positions are realized, and by exchanging the positions of the first push plate and the second push plate, projections of different sizes are realized, which facilitates daily use and improves the The quality of classroom teaching.
