Abstract

An embodiment of the present application provides a push-pull blackboard, which includes an installation frame, a movable writing board, a push-pull mechanism, and a turning assembly. The movable writing board has a vertical writing board surface and the top edge of the board body, and the movable writing board is slidably arranged in the installation frame; the push-pull mechanism includes a driving wheel, a driven wheel and an endless transmission belt, and the driving wheel and the driven wheel are respectively arranged in the mounting frame. At both ends, the driving wheel is connected to the driven wheel through an endless transmission belt; the axis of the driving wheel is parallel to the surface of the writing board and perpendicular to the sliding direction of the movable writing board; the endless driving belt is connected to the top edge of the board body; the first flipping part of the flipping assembly It is connected with one end of the installation frame, the second turning part is connected with the other end of the installation frame, and the endless transmission belt is folded around the first turning part and the second turning part. The above-mentioned push-pull blackboard reduces the height of the endless transmission belt on the top edge of the board body, so that the horizontal frame of the push-pull blackboard can be set narrower, which better solves the problem of the size of the compressed writing area of ​​the horizontal frame.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a push-pull blackboard. Background technique [0002] With the development of large-screen display, touch control technology and the advancement of modern teaching, multimedia blackboards that can be used for smooth writing with ordinary chalk and multimedia display with large-screen LCDs are becoming more and more popular in all walks of life, especially in the field of education. Applications. [0003] At present, the traditional multimedia blackboard is fully fixed, that is, it uses a display screen that can be written and displayed, and is used with a fixed writing board. However, writing on the display screen has the fluency of writing and the clarity of display. This problem is mainly due to the fact that smooth writing requires high roughness, while clear display requires high gloss, and there is a contradiction between the two. Therefore, semi-fixed automatic mult...
