Therefore, no matter to the protection of minor's health, concerning labourer's rights and interests protection still from the angle of advocating environment protection, the transformation and the innovation of traditional blackboard become problem demanding prompt solution.
Three, utility model content
Technical problem:
The utility model is at the deficiencies in the prior art, discloses a kind of rotatable blackboard of the usefulness that is suitable for imparting knowledge to students, and can save instructional blocks of time, reaches the purpose of environment protection health again.
Technical scheme:
Technical solution of the present invention is:
A kind of rotatable blackboard, comprise base plate, the two ends, the left and right sides of base plate are respectively equipped with the first parallel axis of rolling and second axis of rolling, are provided with driving belt on first axis of rolling and second axis of rolling, and driving belt drives first axis of rolling under the control of external motor and second axis of rolling rotates in the same way; Also be with the blackboard cloth of sealing on first axis of rolling and second axis of rolling, blackboard cloth is along with first axis of rolling and second axis of rolling cycle rotation.
As a kind of improvement of the present invention, at least one end at two ends, the base plate left and right sides is provided with the strip brush, and the surface of strip brush closely contacts with blackboard cloth.
As another kind of improvement the of the present invention, the bottom of strip brush is provided with the powder collection box.
As also a kind of improvement of the present invention, a side of base plate is provided with the control button of external motor.
Beneficial effect:
The invention discloses a kind of rotatable blackboard, comprise base plate, the two ends, the left and right sides of base plate are respectively equipped with the first parallel axis of rolling and second axis of rolling, be provided with driving belt on first axis of rolling and second axis of rolling, driving belt drives first axis of rolling under the control of external motor and second axis of rolling rotates in the same way; Also be with the blackboard cloth of sealing on first axis of rolling and second axis of rolling, blackboard cloth is along with first axis of rolling and second axis of rolling cycle rotation.This kind blackboard is suitable for using simultaneously with multimedia teaching, solved the shortcoming that need frequently erase the board because the lantern slide screen blocks half blackboard, the teacher not be used on the classroom and frequently erases the board, healthy useful to Faculty and Students not only, and saved time in classroom.
As a kind of improvement of the present invention, at least one end at two ends, the base plate left and right sides is provided with the strip brush, and the surface of strip brush closely contacts with blackboard cloth.By such design, the strip brush carries out automatic wiping to the blackboard that has write when blackboard cloth rotates, and the teacher just need not erase the board.
As another kind of improvement the of the present invention, the bottom of strip brush is provided with the powder collection box, the dust that Automatic erasing blackboard brought has prevented that dust from flying upward, destroying classroom environment in the classroom, help classroom and student's health like this after collecting by the powder collection box.
As also a kind of improvement of the present invention, a side of base plate is provided with the control button of external motor, and the teacher can control the rotation of blackboard cloth easily.
