Problem to be solved in the utility model is: provide a kind of simple in structure, facilitate the word on erasing blackboard and the education and instruction blackboard of the Health cost that can avoid causing because of chalk powder.
In order to address the above problem, education and instruction blackboard of the present utility model, comprise sheet frame and plate body, in described sheet frame, be provided with two sliding doors that can horizontally slip, the slip blackboard eraser that is each side provided with a strip of described plate body, the both sides of described plate body are respectively provided with a rectangular enclosure, in described each rectangular enclosure, be equipped with a rotating shaft, in described rotating shaft, be socketed with a toothed disc, the edge of described toothed disc is hinged with a connecting rod, other one end and the slip blackboard eraser of described connecting rod are hinged, the below of described toothed disc is provided with a driving gear, described driving gear is meshed with toothed disc, described driving gear is provided with a crank that drives driving gear to rotate.
Education and instruction blackboard of the present utility model, the length of described slip blackboard eraser is identical with the width of plate body.
Education and instruction blackboard of the present utility model, described sliding door is provided with handle, and the size of described sliding door is identical with the size of rectangular enclosure, and the height of described sliding door is identical with the height of plate body, and the length of described sliding door is half of plate body length.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) when the word on erasing blackboard, promote sliding door, with sliding door, the plate body of blackboard is covered, then shake respectively the crank at plate body two ends, under the drive of crank, driving gear driven gear dish rotates, toothed disc is when rotating, by connecting rod, drive slip blackboard eraser to move back and forth, thereby the word on plate body is wiped, in the process of wiping, because sliding door all hides whole plate body, thereby chalk powder can not fly upward, thereby make teacher and student can not suck chalk powder everywhere, guaranteed teacher and student's health; (3) when not needing to wipe word, two sliding doors are pushed into the place ahead of two rectangular enclosures, plate body is come out, driving gear, toothed disc and connecting rod can also be covered up simultaneously, both facilitated writing words on plate body, driving mechanism can be hidden again, make whole blackboard elegant in appearance; (4) length of slip blackboard eraser is identical with the width of plate body, thereby can disposable word on plate body all be wiped totally; (5) size of sliding door is identical with the size of rectangular enclosure, the height of sliding door is identical with the height of plate body, the length of sliding door is half of plate body length, thereby when using plate body, sliding door can hide rectangular cavities, when need on erasing blackboard word time, the plate body of whole blackboard can be hidden completely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model while clashing word.
Fig. 2 is structural representation of the present utility model while not wiping word.
In figure: 1, sheet frame, 2, sliding door, 3, plate body, 4, slip blackboard eraser, 5, rectangular enclosure, 6, toothed disc, 7, driving gear, 8, crank, 9, rotating shaft, 10, connecting rod, 11, handle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated.
As depicted in figs. 1 and 2, education and instruction blackboard of the present utility model, comprise sheet frame 1 and plate body 3, in described sheet frame 1, be provided with two sliding doors that can horizontally slip 2, the slip blackboard eraser 4 that is each side provided with a strip of described plate body 3, the both sides of described plate body 3 are respectively provided with a rectangular enclosure 5, in described each rectangular enclosure 5, be equipped with a rotating shaft 9, in described rotating shaft 9, be socketed with a toothed disc 6, the edge of described toothed disc 6 is hinged with a connecting rod 10, other one end and the slip blackboard eraser 4 of described connecting rod 10 are hinged, the below of described toothed disc 6 is provided with a driving gear 7, described driving gear 7 is meshed with toothed disc 6, described driving gear 7 is provided with a crank 8 that drives driving gear 7 to rotate, the length of described slip blackboard eraser 4 is identical with the width of plate body 3, described sliding door 2 is provided with handle 11, and the size of described sliding door 2 is identical with the size of rectangular enclosure 5, and the height of described sliding door 2 is identical with the height of plate body 3, and the length of described sliding door 2 is half of plate body 3 length.
Education and instruction blackboard of the present utility model, simple in structure, as shown in Figure 1, in the time of word on erasing blackboard, promote sliding door 2, with sliding door 2, the plate body of blackboard 3 is covered, then shake respectively the crank 8 at plate body 3 two ends, under the drive of crank 8, driving gear 7 driven gear dishes 6 rotate, toothed disc 6 is when rotating, by connecting rod 10, drive slip blackboard eraser 4 to move back and forth, thereby the word on plate body 3 is wiped, in the process of wiping, because sliding door 2 all hides whole plate body 3, thereby chalk powder can not fly upward everywhere, thereby make teacher and student can not suck chalk powder, guaranteed teacher and student's health.
When not needing to wipe word, as shown in Figure 2, two sliding doors 2 are pushed into the place ahead of two rectangular enclosures 5, plate body 3 is come out, driving gear 7, toothed disc 6 and connecting rod 10 can also be covered up simultaneously, both facilitate writing words on plate body 3, and driving mechanism can have been hidden again, and made whole blackboard elegant in appearance.
The length of slip blackboard eraser 4 is identical with the width of plate body 3, thereby can disposable word on plate body 3 all be wiped totally.
