Abstract

The invention discloses a movable explanation board for teaching. The movable explanation board for teaching comprises a main board, a hydraulic cylinder and a base. The middle portion of the top endof the base is fixedly connected with the bottom end of the hydraulic cylinder. The piston rod of the hydraulic cylinder is fixedly connected with one end of the hydraulic rod. The other end of the hydraulic rod is fixedly connected with the middle portion of the bottom end of the rotating groove. The top of the rotating groove is rotationally connected with the bottom of the rotating column. Thetop end of the rotating column is fixedly connected with the middle portion of the bottom end of a bearing strip. The top of the bearing strip is fixedly connected with the bottom of the main plate. The top and the bottom in the main plate are symmetrically provided with sliding grooves. Expansion boards are symmetrically arranged in the main boards in a sleeved manner. The tops and the bottoms ofthe two expansion boards are connected with the two sliding grooves in a sliding manner. According to the movable explanation board for teaching, the expansion boards are symmetrically arranged in the main board in a sleeved manner, when the writing area of the main board is not enough, the expansion boards can be pulled out, the writing face plate is widened, and the problem that the teaching process is influenced due to an excessively small writing area of the writing board is avoided; and one end of the adjusting rod is provided with a pedal, the height of the main board can be more conveniently adjusted, and time and effort are saved.

Description

Technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a movable explanation board for teaching. Background technique [0002] The blackboard is almost the most used equipment in the teaching process. Before the generalization of multimedia teaching, the blackboard was a necessity for teaching. The blackboard can make teaching more convenient for teachers. Teachers can write on the blackboard to write knowledge points and make students Learn more intuitively. [0003] However, traditional blackboards are mostly fixed boards with limited writing content, and in large classrooms, students in the back row cannot clearly see the content on the blackboard, which is even more difficult for open teaching without blackboard. Therefore, we have made improvements to this and proposed a movable explanation board for teaching. Summary of the invention [0004] The main purpose of the present invention is to provide a movable explanation boa...
