Multifunctional teaching show luminous energy blackboard

Abstract

The invention discloses a multifunctional teaching show luminous energy blackboard. The multifunctional teaching show luminous energy blackboard comprises a bottom box, three luminous energy drawing boards, and two white boards and is characterized in that the bottom box is of a hollow cuboid structure, side plates are vertically and fixedly connected to the two sides of the top of the bottom box,the rear side edge of the top of the bottom box is vertically and fixedly connected with a back plate with the height equal to that of the side plates, three first electric cylinders are vertically and fixedly connected to the rear side of the inner bottom of the bottom box, the top of a first piston rod of one first electric cylinder penetrates through the top of the bottom box and is fixedly connected with the center of the bottom of one luminous energy drawing board, the three luminous energy drawing boards are located on the same plane, sliding blocks are fixedly connected to the two sides of the luminous energy drawing board in the middle, the side walls, attached to the luminous energy drawing board on the middle, of the luminous energy drawing boards on the two sides are provided with sliding grooves matched with the sliding blocks, the sliding blocks are arranged in the sliding grooves in a sliding manner, and a rotating shaft is vertically and fixedly connected to the front of each side plate. The blackboard is convenient to use and move, and indoor air can be prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of a light energy blackboard, in particular to a multifunctional light energy blackboard for teaching and display. Background technique [0002] The blackboard is the most traditional teaching aid in the teaching process. It is mainly used for blackboard writing and drawing in the classroom during the teaching process. After the teacher uses chalk to write or draw on the blackboard or make annotations, it can be erased and corrected in time. In order to facilitate the normal progress of the next class, the current common practice is to arrange for students on duty to use blackboard erasers to erase. When erasing, chalk dust will scatter around, causing a certain degree of pollution to the air in the classroom. If it enters the human body, it will cause certain harm; for blackboards with less writing on the blackboard, the workload of the students on duty is relatively small, but for blackboards with more wri...

[0002] The blackboard is the most traditional teaching aid in the teaching process. It is mainly used for blackboard writing and drawing in the classroom during the teaching process. After the teacher uses chalk to write or draw on the blackboard or make annotations, it can be erased and corrected in time. In order to facilitate the normal progress of the next class, the current common practice is to arrange for students on duty to use blackboard erasers to erase. When erasing, chalk dust will scatter around, causing a certain degree of pollution to the air in the classroom. If it enters the human body, it will cause certain harm; for blackboards with less writing on the blackboard, the workload of the students on duty is relatively small, but for blackboards with more writing on the blackboard, the workload of the students on duty is relatively large, which occupies a certain extent Too much time for students to spend time between classes. In addition, because some teachers write on the blackboard at a high position, especially for primary and junior high school students, due to individual differences, it is difficult for students on duty to touch the writing on the blackboard at a higher position on the blackboard, resulting in erasure.

Furthermore, since the traditional blackboard is fixed on the wall, it is inconvenient to move
