Summary of the invention
In order to solve above Problems existing, it is provided that a kind of disjunctor blackboard, including a blackboard, the upper and lower both sides of blackboard are respectively arranged with a chute, having a strip blackboard eraser on blackboard, contour with blackboard, there is multiple roller at blackboard eraser two, roller can have slip by oneself in chute, has one handle, and one end is positioned on roller.Blackboard eraser outer layer is a plank, and internal layer is clean layer, and clean layer fits tightly with blackboard.
During use, turning handle, drive roller to rotate, roller makes blackboard eraser transverse shifting, makes clean layer blackboard wiping simultaneously, the letter written with chalk wiped clean on blackboard.
Above-mentioned disjunctor blackboard, wherein, handle can be made of plastics, it is also possible to is made of metal.
Above-mentioned disjunctor blackboard, wherein, clean layer can be made up of sponge, it is also possible to is made up of cotton.
Above-mentioned disjunctor blackboard, wherein, roller can be 4, or is 6, or is 8.
Above-mentioned disjunctor blackboard, wherein, chute can be made of plastics, it is also possible to is made of metal.
Compared with prior art, the present invention has following significant beneficial effect: easy to use, and blackboard wiping is quickly and effectively.
Accompanying drawing explanation
Fig. 1 is the front view of the disjunctor blackboard of the present invention,
Fig. 2 is the side cross-sectional, view of the disjunctor blackboard of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
In conjunction with Fig. 1, shown in Fig. 2, a kind of disjunctor blackboard, including a blackboard 1, blackboard about 1 both sides are respectively arranged with a chute 2, having a strip blackboard eraser 3 on blackboard 1, contour with blackboard 1, there is multiple roller 5 at blackboard eraser 3 two, roller 5 can have slip by oneself in chute 2, having one handle 4, one end is positioned on roller 5, and handle 4 can with the center of roller 5 for axis rotation.Blackboard eraser 3 outer layer is a plank 6, and internal layer is clean layer 7, and clean layer 7 fits tightly with blackboard 3.
During use, turning handle 4, handle 4 drives roller 5 to rotate, and roller 5 makes blackboard eraser 3 transverse shifting, makes clean layer 7 blackboard wiping 1 simultaneously, the letter written with chalk wiped clean on blackboard 1.
Further, above-mentioned disjunctor blackboard, wherein, handle 4 can be made of plastics, it is also possible to is made of metal.
Further, above-mentioned disjunctor blackboard, wherein, clean layer 7 can be made up of sponge, it is also possible to is made up of cotton.
Further, above-mentioned disjunctor blackboard, wherein, roller 5 can be 4, or is 6, or is 8.
Further, above-mentioned disjunctor blackboard, wherein, chute 2 can be made of plastics, it is also possible to is made of metal.
In sum, by using above-mentioned disjunctor blackboard, make blackboard-cleaning get up faster and better, namely save the time, save again the muscle power of wiper.
The foregoing is only preferred embodiment of the present invention; not thereby restriction embodiments of the present invention and protection domain; to those skilled in the art; the equivalent replacement done by all utilizations description of the present invention and diagramatic content and the obtained scheme of apparent change should be can appreciate that, all should be included in protection scope of the present invention.
