Be provided with tooth at left blackboard and right blackboard top edge or lower limb, be provided with gear train at the middle part of square mounting groove, gear train comprises forward gear and reverse gear, and forward gear and reverse gear engage with the tooth of left blackboard and right blackboard edge.
Described gear train also comprises driving wheel, driving wheel be connected with the second motor and and forward gear and reverse gear engage.
Described twist belt drive frame, push rod, sliding part form blackboard cleaning assemblies, are provided with dust receiver outside blackboard cleaning assemblies.
Described twist belt drive frame comprises cross one another first body of rod of many groups and second body of rod, and be flexibly connected between first body of rod and second body of rod, first body of rod and second body of rod are provided with active connection in end.
Described active connection comprises cross sliding clock, and slide block is provided with cell body, establishes positioning cylinder in cell body, and twist belt drive frame is rotationally connected in end and positioning cylinder, and sliding part is provided with the body of rod, and cross sliding clock is slidably located on the body of rod.
The utility model achieves following technique effect:
Adopt said structure, left blackboard and right blackboard can interlock sliding transform position, hairbrush is well made to carry out wiping to the blackboard with letter written with chalk by moving up and down of sliding part two pieces of blackboard evolutions after write a full blackboard like this, the free of discontinuities that can realize blackboard is write, and significantly improves the efficiency of teaching of teacher;
Employing sliding part is rectangular-shaped piece, and hairbrush to be located on sliding part and structure between sliding part and blackboard, can large area, efficiently wiping is carried out to blackboard;
Adopt and be provided with gear train at the middle part of square mounting groove, gear train comprises forward gear and reverse gear, the structure that the tooth of forward gear and reverse gear and left blackboard and right blackboard edge engages, and well can realize the slip of left and right blackboard like this;
Adopt gear train also to comprise driving wheel, the structure that driving wheel is connected with motor also and forward pinion and reverse pinion engage, can well make two pieces of blackboards shift one's position by forward gear and reverse gear like this under the driving of motor;
Adopt the structure being provided with dust receiver outside blackboard cleaning assemblies, can be limited by the chalk dust that hairbrush brush falls like this and be collected in receiver, can prevent chalk dust four from faling apart like this and the healthy of people is impacted.
