Description

A kind of blackboard of automatic removing writing
Technical field
The utility model relates to a kind of blackboard, particularly a kind of blackboard of automatic removing writing.
Background technology
Blackboard is a kind of important teaching aid, although current multimedia teaching is widely used, but in field research practice, no matter be teachers in primary and middle schools or college professor, still based on traditional teaching method, and in traditional teaching method, lecture contents generally can write on the blackboard by teacher, thus need constantly on blackboard, to use chalk-writing, wipe afterwards, write the new content of courses more afterwards, when the word that erasing blackboard is write, owing to there is no special auto-erasing device, manual mode can only be adopted to wipe, not only very tired, and the chalk powder danced in the air everywhere can affect the physical and mental health of teacher.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, can the blackboard of automatic removing writing of word on auto-erasing blackboard.
In order to solve the problems of the technologies described above, the blackboard of automatic removing writing of the present utility model, comprise sheet frame and be fixed on the plate body in sheet frame, a slide bar paralleled with horizontal plane is all fixed with above and below described sheet frame, the erasing plate that one piece of energy swings along slide bar is provided with between described two slide bars, described erasing plate is fixed with a motor, described motor is provided with driving shaft, described driving shaft is fixed with driven wheel, described erasing plate is provided with along its length the some rotating shafts perpendicular to erasing plate, the top of described rotating shaft is fixed with travelling gear, the bottom of described rotating shaft is fixed with hairbrush, the bottom of described hairbrush abuts on plate body, the travelling gear that described driven wheel is adjacent is meshed, also be meshed between the travelling gear that described travelling gear is adjacent, the side of described sheet frame is fixed with a cylinder, described cylinder is provided with push rod, the top of described push rod is fixedly connected with erasing plate.
In order to make erasing plate uniform force, can smoothly along sliding bar, the blackboard of automatic removing writing of the present utility model, the top of described push rod is fixedly connected with the center of erasing plate.
In order to improve the happy degree of erasing plate along sliding bar further, the blackboard of automatic removing writing of the present utility model, the two ends of described erasing plate are all fixed with a sliding bearing, and described sliding bearing is socketed on slide bar.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) in time needing the word on erasing blackboard, start cylinder and motor, erasing plate is under the drive of cylinder, left and right reciprocal along sliding bar, and after electric motor starting, driving shaft just starts to rotate, under the drive of driving shaft, driven wheel starts to rotate, driven wheel is while rotation, owing to engaging each other with adjacent travelling gear, and the travelling gear that travelling gear is adjacent also engages each other, thus under the drive of driven wheel, all travelling gears all rotate with identical speed, and travelling gear is when rotation, rotating shaft and hairbrush will be driven to rotate, bottom due to hairbrush abuts on plate body, thus can rapidly by the word erasing on the plate body of its process, compared with existing artificial erase mode, erasing speed is fast, and can avoid in chalk powder suction body, thus avoid the injury to health that brings because erasing the board for a long time, (3) top of push rod is fixedly connected with the center of erasing plate, thus wipes plate uniform force, guarantees that erasing plate is smoothly along sliding bar, (4) two ends of wiping plate are all fixed with a sliding bearing, and sliding bearing is socketed on slide bar, can reduce erasing plate further along resistance during sliding bar, improve the smooth and easy degree that erasing plate slides further.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view in A-A face in Fig. 1.
In figure: 1, sheet frame, 2, plate body, 3, slide bar, 4, erasing plate, 5, driven wheel, 6, motor, 7, travelling gear, 8, rotating shaft, 9, push rod, 10, cylinder, 11, hairbrush.
Detailed description of the invention
As depicted in figs. 1 and 2, the blackboard of automatic removing writing of the present utility model, the plate body 2 comprising sheet frame 1 and be fixed in sheet frame 1, a slide bar paralleled with horizontal plane 3 is all fixed with above and below described sheet frame 1, the erasing plate 4 that one piece of energy swings along slide bar 3 is provided with between described two slide bars 3, described erasing plate 4 is fixed with a motor 6, described motor 6 is provided with driving shaft, described driving shaft is fixed with driven wheel 5, described erasing plate 4 is provided with along its length the some rotating shafts 8 perpendicular to erasing plate 4, the top of described rotating shaft 8 is fixed with travelling gear 7, the bottom of described rotating shaft 8 is fixed with hairbrush 11, the bottom of described hairbrush 11 abuts on plate body 2, the travelling gear 7 that described driven wheel 5 is adjacent is meshed, also be meshed between the travelling gear 7 that described travelling gear 7 is adjacent, the side of described sheet frame 1 is fixed with a cylinder 10, described cylinder 10 is provided with push rod 9, the top of described push rod 9 is fixedly connected with erasing plate 4, the top of described push rod 9 is fixedly connected with the center of erasing plate 4, the two ends of described erasing plate 4 are all fixed with a sliding bearing, and described sliding bearing is socketed on slide bar 3.
The blackboard of automatic removing writing of the present utility model, structure is simple, in time needing the word on erasing blackboard, start cylinder 10 and motor 6, erasing plate 4 is under the drive of the push rod 9 of cylinder 10, reciprocal the sliding along slide bar 3 in left and right, and after motor 6 startup, driving shaft just starts to rotate, under the drive of driving shaft, driven wheel 5 starts to rotate, driven wheel 5 is while rotation, owing to engaging each other with adjacent travelling gear 7, and the travelling gear 7 that travelling gear 7 is adjacent also engages each other, thus under the drive of driven wheel 5, all travelling gears 7 all rotate with identical speed, and travelling gear 7 is when rotation, rotating shaft 8 and hairbrush 11 will be driven to rotate, bottom due to hairbrush 11 abuts on plate body 2, thus can rapidly by the word erasing on the plate body 2 of its process, compared with existing artificial erase mode, erasing speed is fast, and can avoid in chalk powder suction body, thus avoid the injury to health that brings because erasing the board for a long time.
The top of push rod 9 is fixedly connected with the center of erasing plate 4, thus wipes plate 4 uniform force, guarantees that erasing plate 4 is smoothly along sliding bar.
The two ends of erasing plate 4 are all fixed with a sliding bearing, and sliding bearing is socketed on slide bar 3, can reduce the resistance of erasing plate 4 when sliding along slide bar 3 further, improve the smooth and easy degree that erasing plate 4 slides further.
