Description
Technical field
The present invention relates to a kind of intelligent Wiping-free blackboard, belongs 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 Wiping-free 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 Wiping-free blackboard, including：Transparent blackboard body, it is regularly arranged in the blackboard body to have some ellipses empty
Chamber, rotatable oval magnetic pole is provided with the cavity, the front and rear surfaces of the cavity are provided with opening, described
Spacing is provided between cavity, magnetic sheet is provided with front of the blackboard body, the magnetic sheet top is connected in fix bar, described
Magnetic sheet is in broken line type, and the magnetic sheet bottom is connected with drawstring, and pencil box is provided with below the blackboard body, is set in the pencil box
Be magnetic pen.
The spacing is the distance for avoiding occurring between the adjacent magnetic pole magnetic disturbance.
The front and rear surfaces of blackboard body described in the long axis connection of the cavity, the short axle of the cavity and the length of the magnetic pole
Axle is interference fitted, and the spacing is the 1/3 ~ 1/2 of the minor axis length of the cavity.
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 short axle of the cavity is the 1/1000 ~ 1/100 of the blackboard body length.
A kind of intelligent Wiping-free blackboard provided by the invention, oval magnetic pole are freely rotatable, and N, S pole can exchange rapidly, ellipse
N, S pole of round pole are respectively white and black, when magnetic sheet is located at before blackboard body, are influenceed by the magnetic force of magnetic sheet, ellipse
Towards one side, blackboard body is black or white, then packs up magnetic sheet for the same pole of round pole, when needing to use magnetic pen book
When writing writing on the blackboard, the writing end of magnetic pen and the writing surface magnetic pole of blackboard body are on the contrary, can to write magnetic pen local
Oval magnetic polarity reversal, the place for writing magnetic pen is different from the local color do not write, that is, shows in writing
Hold, when needing to erase the board, only need to put down magnetic sheet again, you can blackboard is restored, therefore the present invention easily writing and erasing, no powder
Dirt, it is safe and healthy.
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 Wiping-free blackboard, including：Transparent blackboard body 1, the blackboard body 1 is interior to advise
Some oblong cavities 2 are then arranged with, rotatable oval magnetic pole 3 is provided with the cavity 2, the cavity 2
Front and rear surfaces are provided with opening 4, and spacing is provided between the cavity 2, and the front of the blackboard body 1 is provided with magnetic sheet 5,
The top of magnetic sheet 5 is connected in fix bar 6, and the magnetic sheet 5 is in broken line type, and the bottom of magnetic sheet 5 is connected with drawstring 8, the blackboard
The lower section of body 1 is provided with pencil box, and magnetic pen 7 is provided with the pencil box.
The spacing is the distance for avoiding occurring between the adjacent magnetic pole 3 magnetic disturbance.
The front and rear surfaces of blackboard body 1 described in the long axis connection of the cavity 2, the short axle of the cavity 2 and the magnetic pole 3
Major axis interference fit, the spacing for the cavity 2 minor axis length 1/3 ~ 1/2.
The bottom of magnetic sheet 5 is provided with retainer ring, and the drawstring 8 is connected with the retainer ring, and the bottom of drawstring 8 is connected with
Handle.
The material of the blackboard body 1 is magnetic-permeable material.
The short axle of the cavity 2 is the 1/1000 ~ 1/100 of the length of blackboard body 1.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
