Preferably, described blackboard surface adopts the high duty alloy steel plate being coated with wear-resistant coating.
Preferably, described blackboard panel is curved surface.
Preferably, described first blackboard and the second blackboard can slide up and down.
Preferably, described 3rd blackboard and the 4th blackboard can slide up and down.
Compared with prior art, the beneficial effects of the utility model are: this blackboard is for full-automatic, the push-and-pull of blackboard can be regulated by the button on remote controller, and can be erased the board by the button on remote controller, 4 pieces of blackboards can be wiped simultaneously, also wipe wherein one piece of blackboard by the vibrator on blackboard, very convenient, and greatly reduce the injury of chalk dust to academics and students, decrease the consumption of teacher's muscle power simultaneously, alleviate the burden of teacher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 housing, 2 blackboard surfaces, 3 inside casings, 4 first blackboards, 5 second blackboards, 6 vibrations receivers, 7 vibrators, 8 axis, 9 motor, 10 motor receivers, 11 first rotating shafts, 12 second rotating shafts, 13 the 3rd blackboards, 14 the 4th blackboards, 15 infrared ray indicator lamps, 16 master switch, 17 vibration switch, 18 remote controllers, 19 push-and-pull switches, 20 blackboards.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of full-automatic push-and-pull blackboard, comprise remote controller 18 and blackboard 20, blackboard 20 comprises housing 1, first blackboard 4, second blackboard 5, 3rd blackboard 13 and the 4th blackboard 14, axis 8 is provided with in the middle of housing 1, motor 9 and motor receiver 10 is provided with in axis 8, described motor 9 is connected with the first blackboard 4 and the second blackboard 5 by the first rotating shaft 11, motor 9 is connected with the 3rd blackboard 13 and the 4th blackboard 14 by the second rotating shaft 12, first blackboard 4, second blackboard 5, 3rd blackboard 13 and the 4th blackboard 14 comprise blackboard surface 2, inside casing 3, vibrations receiver 6 and vibrator 7, vibrations receiver 6 and electromagnetic shaker 7 are arranged on four angles of the first blackboard 4, remote controller 18 comprises infrared indicator lamp 15, master switch 16, vibration switch 17 and push-and-pull switch 19, infrared indicator lamp 15 is arranged on the top of remote controller 18, master switch 16, vibration switch 17 and push-and-pull switch 19 are arranged on the surface of remote controller 18.Blackboard surface 2 adopts the high duty alloy steel plate being coated with wear-resistant coating.Blackboard 20 plate face is curved surface.First blackboard 4 and the second blackboard 5 can slide up and down.3rd blackboard 13 and the 4th blackboard 14 can slide up and down.
