Abstract

The invention provides a teaching blackboard capable of switching display, which comprises a mounting box provided with a display window and a plurality of blackboards arranged in the mounting box in parallel, and the mounting box is divided into an upper chamber and a lower chamber; the plurality of blackboards can slide in the rear of the blackboard display direction in the upper chamber, the blackboards can slide in the front of the blackboard display direction in the lower chamber, the blackboards can move upwards into the upper chamber when sliding to the foremost side of the lower chamber, and the blackboards can move downwards into the lower chamber when sliding to the rearmost side of the lower chamber; and the two side walls of the lower chamber are each provided with a first driving unit used for driving the lower chamber to slide forwards in the blackboard display direction, and the two side walls of the upper chamber are each provided with a second driving unit used for driving the upper chamber to slide backwards in the blackboard display direction. The blackboard of the invention is suitable for installation and use of multiple blackboards in small classrooms, free switching of the blackboards in the upper chamber and the lower chamber is achieved through the first driving unit and the second driving unit, and teaching personnel can write and display conveniently.

Description

technical field [0001] The invention relates to a blackboard for teaching, in particular to a blackboard with switchable display for teaching. Background technique [0002] In the teaching process, the blackboard is widely used as a traditional display teaching aid. However, due to the limited writing area of ​​the blackboard, the teaching staff needs to wipe it many times during the teaching process, which affects the continuity of teaching. It also affects students' understanding of follow-up classes and affects the quality of teaching; in view of the existing problems, many classrooms design multiple blackboards in front of the classroom to facilitate the writing of teaching staff; however, the classroom is limited by the classroom area, and multiple blackboards cannot be installed in parallel Blackboard for teaching and display. Contents of the invention [0003] The object of the present invention is to provide a blackboard with switchable display for teaching, which...
