Description
Technical field
The present invention relates to teaching equipment field, and in particular to a kind of Magnetic dustless blackboard.
Background technology
Blackboard is a kind of articles for daily use, and the thing of classroom's indispensability.Make and use is all very convenient, but
On classroom, teacher wants the class offerings of full record on frequent blackboard wiping, and slot milling records other class offerings.In teacher
When erasing the board, substantial amounts of time in classroom is not only occupied, while also brings more labours to teacher, consumes the body of teacher
Power.In addition, teacher when erasing the board, can produce substantial amounts of chalk dust, teacher is easy to suck substantial amounts of chalk dust, to teacher's
Body produces very big harm, meanwhile, in routine use, usually because of reflective problem the classmate on both sides can be caused not see
The content write on blackboard.
The content of the invention
To solve the above problems, the invention provides a kind of Magnetic dustless blackboard, can be very good to avoid the reflective of blackboard
Problem, the clear display of writing is ensure that, by contact pilotage pen and magnetic with the use of the writing for realizing content, avoid dust
Generation, ensure that the health of user, carry erasing function, it is easy to use.
To achieve the above object, the technical scheme taken of the present invention is：

Plate face, intermediate layer and shrouding, blackboard panel, intermediate layer and shrouding are sequentially connected from top to bottom is encapsulated as one by blackboard frame
Body, the blackboard panel is made up of many thickly dotted concave-convex cambered surfaces, if storing dry magnetic particle in the intermediate layer, by two
The PE films docking of polygon honeycomb is formed, and tangent with the concave-convex cambered surfaces of blackboard panel；The blackboard eraser includes two ball wires
Thick stick and a magnetic stripe, two ball-screws align with the lower edges of blackboard frame respectively, and magnetic stripe is parallel to blackboard panel and and ground
Right angle setting, the pair of nut of the upper and lower ends of magnetic stripe respectively with two ball-screws link, and upper and lower two ball-screw passes through gear teeth
Bar connects, and so as to realize being synchronized with the movement for upper and lower two pair of nut, such magnetic stripe can stable inswept blackboard panel；It is described
Contact pilotage pen includes a shell and the magnet in a shell, and magnet both ends are respectively N poles and pole, the writing of the front end of magnet
Hold as a needle-like structures.
Preferably, the rack-and-pinion includes master gear, pinion and chain, and master gear is arranged on the ball-screw of lower section
On, on the ball-screw that pinion is mounted above, master gear, pinion are connected by chain to be driven.
Preferably, the blackboard eraser is embedded is arranged in wall.
Preferably, in addition to a handle being connected with master gear, it is arranged on the outside of blackboard body.
Preferably, the blackboard frame is aluminum alloy material.
Preferably, the blackboard body uses PVC material.
Preferably, two ball-screws are affixed with shrouding by support, and two ball-screws pass through deep groove ball bearing and support phase
Even.
The invention has the advantages that：
It can be very good to avoid the reflective problem of blackboard, ensure that the clear display of writing, pass through contact pilotage pen and magnetic
With the use of the writing for realizing content, the generation of dust is avoided, ensure that the health of user, carries erasing function,
It is easy to use.

Embodiment
In order that objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further
Describe in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
As shown in figs 1 to 6, the embodiments of the invention provide a kind of Magnetic dustless blackboard, including blackboard body, contact pilotage pen
And blackboard eraser, the blackboard body include blackboard panel 1, intermediate layer 2 and the shrouding 3 of white, blackboard panel 1, intermediate layer 2 and shrouding
3 are sequentially connected are packaged as a whole by blackboard frame from top to bottom, and the blackboard panel 1 is by many thickly dotted concave-convex cambered surfaces
Form, using the convergence principle of light, would not make when there is font presentation in plate face because of the reflection of light the person of receiving instruction by
Puzzlement, and each word is clearly presented with stroke；If dry magnetic particle is stored in the intermediate layer 2, by two
The PE films docking of polygon honeycomb is formed, and tangent with the concavo-convex lonely face of blackboard panel；So when stylus streaks, magnetic
It is magnetized and attracts, using the principle that is in the light, it can just projects to first layer completely so as to clearly show font because being in the light；
The blackboard eraser includes two ball-screws 4 and a magnetic stripe 5, and two ball-screws 4 align with the lower edges of blackboard frame respectively, magnetic stripe
5 parallel to blackboard panel and installation perpendicular to the ground, and the pair of nut 6 of the upper and lower ends of magnetic stripe 5 respectively with two ball-screws links,
Upper and lower two ball-screw 4 is connected by rack-and-pinion, so as to realize being synchronized with the movement for upper and lower two pair of nut, such magnetic stripe ability
Enough smoothly inswept blackboard panels；Specifically, the rack-and-pinion includes master gear, pinion and chain, master gear is arranged on
On the ball-screw 4 of lower section, on the ball-screw 4 that pinion is mounted above, master gear, pinion are connected by chain to be passed
It is dynamic.The blackboard eraser is embedded to be arranged in wall, is greatly saved space, in addition to a handle being connected with master gear, is set
In the outside of blackboard body.
The contact pilotage pen includes a shell 7 and the magnet 8 in a shell 7, and the both ends of magnet 8 are respectively N poles and S
Pole, the thick marker of the outer likeness in form of a shell, such writer are easier left-hand seat in writing, hold and relaxed than traditional chalk
Clothes are a lot, although profile is like marker, pen core is magnet, the front end of magnet than traditional chalk more carefully, book
The local magnetic that stylus stroke is crossed when writing is magnetized and has certain magnetic, and magnetic is attracted and shows font.This
One design has many advantages compared with traditional chalk, and writer does not have to as the so painstaking can of traditional chalk is word in writing
Body clearly indicates out, less has the puzzlement of chalk foam.The blackboard frame is aluminum alloy material, the blackboard body
Using PVC material, two ball-screws 4 are affixed with shrouding by support, and two ball-screws are connected by deep groove ball bearing 9 with support
During the content being originally embodied on the whole erasing blackboards of needs, swinging handle is only needed master gear is rotated under drive
Screw rod rotates, while drives upper screw rod to rotate rotate pinion by chain drive, so as to be converted into screw pair
It is axially moved, leading screw drives magnetic stripe from left to right to move when rotating clockwise handle, and leading screw drives magnetic when rotating counterclockwise handle
Bar moves from right to left, time saving and energy saving so as to realize erasing function；Using the principle of magnet " same sex attracting, different in nature repel each other ",
During writing, if being write using N poles, then just with S poles, crossing magnetic when stylus stroke has certain magnetic for erasing, when tactile
Pin pen takes away it and still retains those magnetic, when clerical error occurs in writer, as long as contact pilotage pen is gently streaked in turn
With regard to the Magnetic Characteristics of Magnetic Particles being magnetized originally being offset, making magnetic demagnetization and returning to origin-location, just completing erasing function.
Described above is only the preferred embodiment of the present invention, it is noted 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
It is considered as protection scope of the present invention.
