Summary of the invention

The utility model mainly is easily to produce problem such as dust during at existing blackboard function singleness, wiping, and a kind of multi-functional blackboard that can combine with multimedia teaching and be difficult for producing dust is provided.

The purpose of this utility model mainly is achieved by following proposal: a kind of folding utility blackboard, comprise plate body, it also comprises two auxiliary plate bodys, described auxiliary plate body front is a blackboard, reverse side is white projection screen, two auxiliary plate bodys are connected the plate body both sides by Positioning hinge, plate body is provided with wiper, wiper comprises wiper support and wiping brush, the wiping brush is arranged on wiper support tow sides, plate body is provided with the wiper slide rail in two edges up and down, and wiper support and wiper slide rail are slidingly connected.Two auxiliary plate bodys are connected the plate body both sides by Positioning hinge; accessory plate folded body to unspecified angle is fixed; do not rotate; can be during teaching according to front-seat student's actual demand with the accessory plate folded body to suitable fixed angle; make front-seat edge students see writing on the blackboard content on the blackboard easily clearly, the eyesight to the student plays the certain protection effect simultaneously.The reverse side of auxiliary plate body is white projection screen, when carrying out multimedia teaching, will assist the plate body front to fold towards plate body, the reverse side of auxiliary plate body is folded as projection screen, reach the purpose of auxiliary multimedia teaching, make in the classroom curtain need not be set again.Plate body is provided with wiper, only need the wiper on the mobile plate body, get final product Convenient scrubber except that the written contents on the plate body, when the written contents on the auxiliary plate body also needs to wipe, with the accessory plate folded body, positive and the auxiliary plate body of plate body is positive relative, slip wiper support, then the wiping of wiper support positive and negative brush carries out quick wiping to the written contents on plate body and the auxiliary plate body, improved wiping efficient, and because wiping operation carries out in folding space, can not cause chalk dust to fly upward everywhere, alleviate chalk dust the healthy harm that causes of academics and students.When not using blackboard,, save the space with the accessory plate folded body.

As preferably, described plate body and auxiliary plate body front are blackish green dustless magnet board.Dustless magnet board, fluent writing, writing is clear, wipes laborsaving noresidue, and is totally thorough during wiping two sides writing on the blackboard content, and the eyes that blackish green colour table face of while does not stimulate the people help the protection of eyesight.

As preferably, the height of described auxiliary plate body is identical with the plate body height, and the width of plate body is 2 times of auxiliary plate body width.Just big or small together behind the accessory plate folded body with plate body, align good looking appearance just when making the two edges of assisting plate body folding.

As preferably, described wiping brush material is a felt.The slit on felt surface absorbs felt backing with dust granules, and dust should not fly upward, and more laborsaving during wiping.

As preferably, described wiper stent length is identical with the plate body height.Slide in the wiper slideway of two edges about plate body, wiper support two ends, it is identical with the plate body height that the wiper stent length is set to, and can carry out wiping easily.

Therefore, the beneficial effects of the utility model are both to have can be used as blackboard, can also be as projection screen, and dust is less during the higher and wiping of the efficient of wiping simultaneously.
