Rotatable multiple-combination teaching board

Abstract

The invention discloses a rotatable multiple-combination teaching board, which comprises a base, a support plate, a blackboard, an interaction whiteboard, a first support rod, a second support rod and a rolling bearing, wherein one end of the first support rod is connected with the base, the other end of the first support rod is connected with an outer sleeve of the rolling bearing, the blackboard is rotationally connected with one end of the second support rod through an inner sleeve of the rolling bearing, the support plate is arranged at the other end of the second support rod, a groove is formed in the upper end of the second support rod, the support plate is connected with the second support plate through the groove, the blackboard is arranged at one surface of the support plate, and the interaction whiteboard is arranged at the other surface of the support plate. The rotatable multi-combination teaching board has the advantages that by skillfully combining the blackboard and the whiteboard, the space occupation area of the teaching board is greatly reduced, the teaching requirements of different teachers are met, the use time of the blackboard and the whiteboard can be freely adjusted, and the discomfort of eyes caused by the eyes facing the strong light for a long time is avoided.

Description

technical field [0001] The invention relates to a teaching board, in particular to a rotatable multi-combination teaching board. Background technique [0002] At present, with the development of science and technology, more and more high-tech products in teaching boards have gradually replaced the old writing blackboards. Among them, interactive whiteboards are the most widely used and most practical teaching boards in teaching. , its function realizes the interaction between people and the teaching board, making the teaching more vivid, but there are still some teachers who are not used to the use of the interactive whiteboard, preferring to use the blackboard to write the teaching content, but simply The splicing of the blackboard and the interactive whiteboard will take up a lot of space, resulting in a waste of space resources, and if the interactive whiteboard is used for a long time, it will cause eye fatigue and cause myopia and other eye diseases.
