Description
Technical field
The present invention relates to a kind of intelligent blackboard for being easy to wipe writing on the blackboard, belong to education equipment technical field.
Background technology
Prevalence and application with Modern educational methodology, instructors seem increasingly to dote in multimedia teaching, and ignore
The irreplaceable effect of black board teaching on Traditional Classroom.In modern education, black board teaching this Traditional teaching means are still
So play its indispensable effect.Such as compulsory education, teacher asks the upper blackboard of student to do topic often needs large area
Blackboard；The old professor for departing from electronic age is considered further that, situations such as poorer small towns, mountain area or projecting apparatus repair, blackboard
Presence be still necessary.Existing blackboard is to use chalk-writing, and writing is laborious, and erasing the board also wastes time and energy, and powder
There is also harm for the health of teacher and student for dirt.
The content of the invention
Present invention solves the technical problem that being to provide one kind utilizes magnetic pole principle, and easily writing and erasing, no dust, peace
The intelligent blackboard of full health.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of intelligent blackboard for being easy to wipe writing on the blackboard, including：Transparent blackboard body, if regularly arranged in the blackboard body have
Dry cavity, the lateral middle of the cavity are connected with the connecting rod of cylinder, and running through on the connecting rod has the magnetic pole that can be rotated up and down, institute
The length for stating magnetic pole is more than the lateral length of the cavity, and the upper and lower ends of the magnetic pole are different colours, before the cavity
Surface is provided with opening afterwards, and spacing is provided between the adjacent cavity, and magnetic sheet, institute are provided with front of the blackboard body
State magnetic sheet top to be connected in fix bar, the magnetic sheet is in broken line type, and the magnetic sheet bottom is connected with drawstring, under the blackboard body
Side is provided with pencil box, and magnetic pen is provided with the pencil box.
The spacing is the distance for avoiding occurring between the adjacent magnetic pole magnetic disturbance.
The front and rear surfaces of the longitudinally connected blackboard body of the cavity；The spacing is the lateral length of the cavity
1/3 ~ 1/2.
The magnetic sheet bottom is provided with retainer ring, and the drawstring is connected with the retainer ring, and the drawstring bottom is connected with hand
Handle.
The material of the blackboard body is magnetic-permeable material.
The lateral length of the cavity is the 1/1000 ~ 1/100 of the blackboard body length.
It is provided with the middle part of the magnetic pole and is more than the connecting rod for the through hole through the connecting rod, the internal diameter of the through hole
External diameter.
The magnetic pole includes ellipsoid, cuboid or cylinder；The shape of the cavity includes rectangle, cylinder, ellipse
Circular or rhombus.
A kind of intelligent blackboard for being easy to wipe writing on the blackboard provided by the invention, magnetic pole are freely rotatable, and N, S pole can be mutual rapidly
Change, N, S pole of magnetic pole are respectively white and black, when magnetic sheet is located at before blackboard body, are influenceed by the magnetic force of magnetic sheet, magnetic pole
Same pole towards one side, blackboard body be black or white, then packs up magnetic sheet, when need to use magnetic pen writing writing on the blackboard
When, the writing end of magnetic pen and the writing surface magnetic pole of blackboard body are on the contrary, the local magnetic pole that can write magnetic pen is anti-
Turn, the place for writing magnetic pen is different from the local color do not write, that is, shows written contents, when needs are blacked
During plate, magnetic sheet only need to be put down again, you can restore blackboard, therefore easily writing and erasing, no dust are safe and healthy by the present invention.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of cavity in the present invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ Fig. 2, a kind of intelligent blackboard for being easy to wipe writing on the blackboard, including：Transparent blackboard body 1 is described black
Regularly arranged in plate body 1 to have some cavitys 2, the lateral middle of the cavity 2 is connected with the connecting rod 3 of cylinder, on the connecting rod 3
Through there is the magnetic pole 4 that can rotate up and down, the length of the magnetic pole 4 is more than the lateral length of the cavity 2, the magnetic pole 4 it is upper
Lower both ends are different colours, and the front and rear surfaces of the cavity 2 are provided with opening 5, between being provided between the adjacent cavity 2
Away from the front of the blackboard body 1 is provided with magnetic sheet 6, and the top of magnetic sheet 6 is connected in fix bar 7, and the magnetic sheet 6 is in broken line
Type, the bottom of magnetic sheet 6 are connected with drawstring 8, and the lower section of the blackboard body 1 is provided with pencil box, sets and be magnetic in the pencil box
