Stereoscopic overturning blackboard

Abstract

The invention discloses a stereoscopic overturning blackboard which comprises a blackboard framework, board overturning drive mechanisms, a W-shaped blackboard eraser, triangular prism boards and blackboard eraser drive mechanisms, wherein the blackboard eraser drive mechanisms are connected with the triangular prism boards to overturn the triangular prism boards; and the W-shaped blackboard eraser is arranged on the blackboard eraser drive mechanisms which drive the W-shaped blackboard eraser to reciprocate. With adoption of a spatial triangular prism structure, the use areas of the boards are increased, and meanwhile, the blackboard eraser drive mechanisms are matched, so that automatic cleaning is realized, and the class efficiency of a teacher is improved.

Description

technical field [0001] The invention relates to a teaching blackboard, in particular to a three-dimensional turning blackboard. Background technique [0002] Teachers often need to write a lot of writing on the blackboard during the teaching process. After the traditional blackboard is full, erase it and continue writing. [0003] In order to expand the area of ​​the board surface, the existing blackboard often increases the area of ​​the blackboard by moving up and down, but the increased area is limited, and the blackboard needs to be manually wiped. Chinese utility model patent CN 203567411 U discloses an automatic flip blackboard, which is driven by a motor to realize automatic flipping of the board surface. However, when a single panel is turned over, it needs to take up a lot of space and has poor practicability. Chinese invention patent CN 103496268 A discloses a mobile and flip-type blackboard, which is composed of a front and back flip mechanism and a left and righ...

Chinese utility model patent CN 203567411 U discloses an automatic flip blackboard, which is driven by a motor to realize automatic flipping of the board surface, but a single panel needs to take up a lot of space when it is turned over, which is poor in practicability

Chinese invention patent CN 103496268 A discloses a mobile and flip-type blackboard, which is composed of a positive and negative flip mechanism and a left and right movement mechanism. The area of ​​the board surface is increased through space movement and flip, but its structure is complicated and the space requirement is high, so it is not suitable for promotion.
