Detailed description of the invention
This can comprise bracing frame 2, soft blackboard face 1, upper beaming roller 8 and lower roller 9 by synchronous dustproof blackboard of playback formula.Bracing frame 2 is equipped with beaming roller 8 and lower roller 9, one end of lower roller 9 extends to outside bracing frame 2, extends on the lower roller 9 outside bracing frame 2 and handwheel is housed, the turning handle of handwheel is equipped with lockage button 13; The lower roller 9 corresponding with turning handle is equipped with revolving rheostat.
On upper beaming roller 8 and lower roller 9, symmetrically shape is equipped with synchronous pulley 6 respectively, synchronous pulley 6 is equipped with soft blackboard face 1 by Timing Belt 5, the upper beaming roller 8 inside synchronous pulley 6 and lower roller 9 are equipped with regulating wheel 7 respectively by connector 11; Connected by connecting rod 12 between regulating wheel 7 on upper beaming roller 8 and lower roller 9.
Inside bracing frame 2 between upper beaming roller 8 and lower roller 9, symmetry shape is provided with gripper shoe mounting groove 14, and gripper shoe mounting groove 14 is arranged in longitudinal shape.Gripper shoe 3 is installed in gripper shoe mounting groove 14; Inside bracing frame 2 below gripper shoe mounting groove 14, symmetry shape is provided with carriage release lever mounting groove 15, and carriage release lever mounting groove 15 is arranged in horizontal shape.It is recessed that the two ends of carriage release lever mounting groove 15 are respectively arranged with card, and is movably installed with carriage release lever 4 by card is recessed in carriage release lever mounting groove 15, carriage release lever 4 is fixedly connected with connecting rod 12.Be provided with blackboard-cleaning device below lower roller 9, blackboard-cleaning device is made up of lifter 10, housing 16 and wiping hairbrush 17; Housing 16 is opening shape; Lifter 10 is housed bottom housing 16, and in housing 16, symmetry shape is equipped with many group wiping hairbrush 17, and blackboard-cleaning device is connected with soft blackboard face 1 movable contact by wiping hairbrush 17.
This can the synchronous dustproof blackboard of playback formula in use, by promote before and after level carriage release lever 4 move to carriage release lever mounting groove 15 accordingly card recessed in, thus make it drive regulating wheel 7 selectively to engage with the Timing Belt 5 of its front and back end by connecting rod 12; And then make soft blackboard face 1 fit with gripper shoe 3 or be separated, with facilitate teacher write on soft blackboard face 1 and soft blackboard face 1 rotate object.
This can make soft blackboard face 1 rotate around upper beaming roller 8 and lower roller 9 by rotating handwheel by the synchronous dustproof blackboard of playback formula, and what this operation can realize this blackboard can playback function.While soft blackboard face 1 is rotated, by the lockage button 13 on lower handle, the synchronous variable resistance signal of generation can be passed to computer, the effect that mouse rollovers controls computer can be realized; Joining multimedia classroom play content, can realize synchronously stirring effect.When not needing synchronously to stir, by unclamping lockage button 13.
When the writing on soft blackboard face 1 needs wiping, by lifter 10 jacking housing 16, wiping hairbrush 17 is contacted with soft blackboard face 1, the wiping of writing on soft blackboard face 1 can be realized, and can dust from flying be prevented, solve existing chalk dust and fly upward everywhere; To the healthy problem causing very large harm of teacher and classmate.This can the synchronous dustproof blackboard structure of playback formula simple, novel in design, be specially adapted to place to operate schools and install and use.
