Description

The electronic blackboard that rolls

Technical field:

The utility model relates to a kind of teaching aid, particularly a kind of electronic blackboard that rolls.

Background technology:

Traditional blackboard mostly is the blackboard of wooden blackboard, Glass blackboard or metallic plate face, it all is to be fixed on the wall, can not be up and down, and the people who uses has individual difference, there have height to have to be short, the tall person in use often the space of a whole page of lower position utilize fewly, short in use often the space of a whole page of higher position utilize fewly, very inconvenient when writing.And the size of clipboard face fixes, and write area is limited; When wiping letter written with chalk, chalk dust is big, wipes inconvenience.

Summary of the invention:

The purpose of this utility model is: the electric that provides a kind of and have big write area, writes conveniently, can wipe the automatically letter written with chalk blackboard that can roll, and to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises carriage (1) and is installed in blackboard curtain (2) on the carriage (1), be separately installed with passive roller bearing (3) and active roller bearing (4) in the top and bottom of carriage (1), initiatively roller bearing (4) connects motor (5), one end of blackboard curtain (2) is wound on the active roller bearing (4), the other end is wound on the passive roller bearing (3), electronic button (6) is installed on carriage (1), and electronic button (6) connects motor (5).

The back side in carriage (1), and the lower face that is positioned at blackboard curtain (2) is equipped with rolling brush (7).

At the back side of blackboard curtain (2) supporting plate (8) is installed.

Wind (9) is housed on active roller bearing (4).

Be provided with bin (10) in the lower end of carriage (1), be provided with dust storehouse (11) in the below of carriage (1).

Compared with prior art, the utlity model has following advantage:

1, write area is big.Owing to adopt rotatable blackboard curtain as blackboard, make the write area of blackboard can reach infinitely great, can arbitrary writing and needn't be subjected to the restriction of write area;

2, write conveniently.Because the curtain of blackboard can be realized scroll-up/down under the drive of active roller bearing and passive roller bearing, the teacher can write easily all the time in the writing on the blackboard of the position of most convenient when writing like this;

3, can wipe letter written with chalk on the blackboard automatically, convenient erasing not only, and can effectively avoid dust from flying.The utility model is at the back side of carriage, and the surface that is positioned at the blackboard curtain is equipped with rolling brush, when the blackboard curtain that rolls passes through rolling brush, can automatically the letter written with chalk on the blackboard curtain be wiped, brush chalk dust down enters into the dust storehouse that is arranged on the carriage below, to keep ground neatly and avoid dust from flying.

4, use easily.The utility model is equipped with supporting plate at the back side of blackboard curtain, to play a supporting role, is convenient to write, and simultaneously, wind is installed also on the active roller bearing, like this when having a power failure by shaking wind, can guarantee normal use.In addition, the utility model also is provided with bin in the lower end of carriage, is used to place chalk holder teacher's pointer teaching aid etc.

5, structure is simple, cost of manufacture is low.
