The support rod passes through the positioning block and is slidably connected with it. The positioning block is provided with a height positioning button, and the bottom end of the positioning block is provided with a hollow plate with side openings. There is a supporting plate, and two elastic transparent fixing belts are arranged on the surface of the hollow plate from top to bottom, and the base is also provided with a blind hole on the side of the base, and a disc spring is arranged in the blind hole, so that The disc spring is connected with a movable shaft, telescopic cards are arranged on both sides of the movable shaft, the movable shaft is connected with an inlaid lamp holder, the lamp holder is provided with a spotlight, and the lower surface of the base is provided with a runner, The upper surface of the base is provided with a telescopic rod. The end of the telescopic rod is provided with an external thread. The bottom end of the blackboard body is provided with a sleeve that matches the external thread. The hollow board is equipped with a teaching ruler, a drawing board, and a triangular board.

The utility model has reasonable design and complete functions. It can not only effectively support the textbooks, but also facilitate the use of teaching tools. It can also adjust the angle of the blackboard. The spotlights also protect the eyes of the students and effectively improve the classroom teaching efficiency of teachers.

Detailed ways

Preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

A multi-functional teaching blackboard, comprising a blackboard body, a chute is arranged on the top of the blackboard body, a pulley is arranged in the chute, a support rod is fixedly connected to the pulley, and a positioning rod is arranged on the support rod. The support rod passes through the positioning block and is slidably connected with it. The positioning block is provided with a height positioning button, and the bottom end of the positioning block is provided with a hollow plate with side openings. There is a supporting plate, and two elastic transparent fixing belts are arranged on the surface of the hollow plate from top to bottom, and the base is also provided with a blind hole on the side of the base. The disc spring is connected with a movable shaft, telescopic cards are arranged on both sides of the movable shaft, the movable shaft is connected with an inlaid lamp holder, the lamp holder is provided with a spotlight, and the lower surface of the base is provided with a runner. The upper surface of the base is provided with a telescopic rod. The end of the telescopic rod is provided with an external thread. The bottom end of the blackboard body is provided with a sleeve that matches the external thread. The hollow board is provided with a teaching ruler, a drawing board and a triangular board.

When using, the teacher can use two elastic transparent fixing belts for textbooks. The transparent fixing belts are used to fix the textbooks without affecting the teacher’s reading. In this way, when writing Chinese characters on the blackboard, the teacher does not need to look back frequently. The damage to the teacher's cervical spine is reduced; there are teaching rulers, grid boards, and triangular boards in the hollow board, so that teachers do not need to go to the podium to pick up the books when using them, which reduces the workload of teachers and improves the efficiency of classroom teaching. Blackboard erasers and pointers can be placed on the pallet. The base is equipped with rotating wheels to facilitate the movement of the blackboard. The telescopic rod and the external thread cooperate with the sleeve to lift the blackboard, which is convenient for students sitting behind to watch. When using spotlights, the movable shaft is stuck in the blind hole through the telescopic cards on both sides of the movable shaft On the outside, turn the lamp holder connected to the movable shaft upwards to provide lighting. When not in use, shrink the telescopic card on the movable shaft to put the spotlight into the blind hole. Spotlights are very strong and unique to space, color, and virtual reality, which is conducive to protecting students' eyes.

The utility model has reasonable design and complete functions, can not only effectively support textbooks, but also facilitate the use of teaching tools, protect students' eyes, and effectively improve teachers' classroom teaching efficiency.
