It is connected with support by crossbeam bottom axis body, inside described axle sleeve, is provided with the through hole passed for axis body.
It should be noted that flexible panel keeps certain opening under the active force of driven pulley and cleaning wheel
Power so that contact with plate body, it is ensured that the success rate that plate face is write, meanwhile, when to flexible panel one
The power of push-and-pull, then dynamic first, second driven pulley rolling worn by flexible board, and cleaning wheel is to flexible panel
Outer surface (written trace face) is cleaned, when sliding towards some direction, with flexible board face
The cleaning wheel of initial contact has the cleaning face of humidity, it is ensured that chalk trace powder will not occur because of friction
Dirt, and the cleaning wheel contacted below has the cleaning face of dry bath, completes the cleaning to flexible panel,
Owing to cleaning member quantity is some, as long as therefore by the cleaning wheel of the initial contact in both sides, the plate body back side
It is configured with the cleaning face of humidity.
The present invention provides a kind of audio-visual education programme Wiping-free blackboard, and relative to traditional blackboard, it is good convenient to have
Property, operability is very strong, and cleaning member has detachability, convenient periodic replacement cleaning, eliminates
Think the time erased the board, improve teaching efficiency.
