Description
Technical field
The utility model relates to a kind of round pulling formula brush screen magnetic wordpads, belong to a kind of educational aid.
Background technique
Also there is the magnetic wordpad compared with multiple types on the market at present, these magnetic wordpads are by magnetic pen in board
It writes or draws a picture in magnetic plate core, the magnetic powder of board in-core is adsorbed onto the upper surface for plate core of writing by magnetic pen, from
And show text or picture in the upper surface for plate core of writing, when need to remove be located at write text on plate core upper surface or
It when person's picture, is streaked by demagnetizing mechanism in the lower surface for plate core of writing, this makes it possible to will originally be adsorbed to write
The magnetic powder of plate core upper surface falls back to the lower surface for plate core of writing, to reach the word or picture eliminated and write out originally with magnetic pen
The purpose of figure out.
Such as publication date is on 03 21st, 2001, in the Chinese patent of Publication No. CN2424021, discloses a kind of magnetic
Board is controlled, which is made of board, plate face blackboard eraser, fixed border, magnetic writing pen, and board is mounted in substrate
On, two sides are equipped with slideway to substrate up and down, and blackboard eraser slide arm is pressed from both sides by the slideway on upper and lower roller box, is installed on substrate up and down slideway,
On U-shaped slide bar, U-shaped slide bar both ends are separately fixed on roller box up and down plate face blackboard eraser, have control knob on plate face blackboard eraser.The magnetic
Controlling the portion of the handle of plate face blackboard eraser in board is exposed outside fixed border, leads to the appearance of board unsightly, and
The reset of plate face blackboard eraser is inconvenient, leads to the inconvenient for use of magnetic control board.
Although the type of existing magnetic wordpad is more, existing magnetic wordpad usually there will be it is following not
Foot: demagnetization structure mainly includes the slide bar with magnetic stripe, and the hand-held part of the slide bar is exposed at the outside of shell, in use, slide bar from
Board slides into another side on one side, to achieve the purpose that board demagnetization, on the one hand, the hand-held part of slide bar is exposed at shell
Outside, lead to the appearance of board unsightly, on the other hand, be not provided with resetting apparatus in demagnetizing mechanism, lead to degausser
The reset of structure is inconvenient, in addition, active force acts predominantly on one end of slide bar when with rubber sleeve moving slide-bar, due to slide bar itself compared with
It is long, cause slide bar that can often block in sliding, operation is not very flexibly, to thus greatly reduce the quality of board.
