Multifunctional mechanized assembled teaching blackboard device

Abstract

The embodiment of the invention discloses a multifunctional mechanized assembled teaching blackboard device. The multifunctional mechanized assembled teaching blackboard device comprises a supportingrack embedded into a wall body and a combined blackboard arranged on the supporting rack, wherein the combined blackboard comprises a side pull combination block positioned at the upper half part anda functional combination block positioned at the lower half part; the side pull combination block at least comprises two side pull plates; the functional combination block at least comprises multiplegroups of rotated plates capable of turning over towards the outer side; the supporting rack comprises a first side frame for movably mounting the side pull combination block, a second side frame formovably mounting the functional combination block as well as a rail rack for storing the side pull plates pulled from the first side frame to the outer side for moving; self-ejection type side pull plate supplying cavities which are in one-to-one correspondence to the side pull plates are formed in the first side frame; and self-ejection type rotated plate supplying cavities which are in one-to-one correspondence to various groups of rotated plates are formed in the second side frame. The multifunctional mechanized assembled teaching blackboard device realizes the effects of enlarging the teaching and writing space, increasing the answering space and improving the teaching quality and the teaching efficiency.

Description

Technical field [0001] The embodiment of the invention relates to the field of blackboard structures for teaching, in particular to a multifunctional mechanized assembly type teaching blackboard device. Background technique [0002] As an indispensable writing tool in teaching, blackboards bring great convenience to teachers' teaching work. In the actual teaching process, it is based on the interaction between the blackboard and the students to improve the students' learning concentration. [0003] Even if the existing blackboard is only used for teaching by teachers, its size and classroom space often have certain limitations. For example, if the blackboard is too large, the content in the corner of the blackboard will not be able to spread to all students in the classroom. In reality, there are also various external factors such as reflections, which further limit the size of the blackboard and classroom space, making it often difficult to meet the teaching content of a class.

[0003] However, even if the existing blackboard is only used for teaching by teachers, its size and classroom space often have certain limitations. For example, if the blackboard is too large, the content in the corner of the blackboard cannot be spread across the field of vision of all students in the classroom. In addition, there are various external factors such as reflections in reality, which further restrict the size of the blackboard and classroom space, making it often difficult to meet the teaching content of a class. In order to spread the students' vision, the teaching content is often written in the middle of the blackboard , but teachers need to wipe repeatedly to keep writing new teaching content for classroom teaching, wasting a lot of wiping time, and writing content on the blackboard is relatively slow

[0004] On this basis, if we further increase the interaction in the teaching process, we will inevitably need to add a certain amount of writing and interaction space during the interaction process, which will cause problems such as insufficient blackboard use area, reduced teaching quality, and a large amount of additional wiping time.
