Abstract

The utility model discloses a magnetic blackboard. The magnetic blackboard comprises a blackboard body, a rectangular frame and a magnetic pen, wherein the blackboard body comprises a base body, plastic cement, a writing board and a magnetic powder layer which is uniformly distributed on the plastic cement; the writing board, the magnetic powder layer, the plastic cement and the base body are fixed on the frame in sequence from top to bottom in a stack mode; guide rails are respectively arranged on the upper part and the lower part of the frame; and a degaussing rubbing block which can move horizontally along the guide rails is arranged between the upper guide rail and the lower guide rail of the frame. By the magnetic blackboard, the influence of chalk dust on human health can be avoided; and simultaneously, when the writing is erased, the labor is relatively saved.

Description

Magnet board

Technical field

The utility model relates to a kind of teaching aid, relates in particular to a kind of magnet board.

Background technology

Blackboard is the teaching aid of commonly using, when using traditional black board teaching, because being uses chalk to write on blackboard, therefore, when with blackboard eraser erasing chalk writing, can cause dust from flying, the dust that flies upward can be sucked by teacher or student, thereby the health of health is caused adverse effect.

Summary of the invention

In view of this, the utility model provides a kind of magnet board, writes on magnet board by adopting magnetic pen, and comes erasing out handwriting by the demagnetization blackboard eraser, thereby avoid causing impact on person health because of dust from flying.

The utility model solves the problems of the technologies described above by following technological means:

The utility model provides a kind of magnet board, comprise the blackboard body, the framework that is rectangle and magnetic pen, described blackboard body comprises matrix, plastic cement, clipboard, and be evenly distributed on magnetic blow out coating on described plastic cement, described clipboard, magnetic blow out coating, plastic cement and matrix stack gradually from top to bottom and are fixed on described framework, described framework be respectively equipped with up and down guide rail, be provided with between described framework upper/lower guide and can wipe piece along the demagnetization that this guide rail moves left and right.

Further, described demagnetization is wiped two ends, piece up and down and is separately installed with roller, and described roller matches with the guide rail of described framework.

Further, described magnet board also comprise be arranged on described framework top be used for drive described demagnetization wipe the drive motors that piece moves left and right between described guide rail, the output shaft of described drive motors is connected with the roller of described demagnetization wiping piece one end.

Further, the centre of described demagnetization wiping piece is provided with the Handheld Division.

Implement the beneficial effects of the utility model:

Magnet board of the present utility model, by between matrix and clipboard, magnetic blow out coating being set, when needs are write, by magnetic pen, magnetic magnetized and form word on clipboard, when the needs erasing out handwriting, directly wiping piece by demagnetization magnetic is carried out demagnetization, it is the residual magnetism on the demagnetization magnetic, make magnetic get back to again on matrix, simple clean in this process, avoided the impact of dust on health; Simultaneously, the utility model arranges guide rail on blackboard framework, and demagnetization is wiped piece two ends roller is set, and is more laborsaving when making erasing out handwriting.

The utility model drives demagnetization wiping piece by drive motors and moves left and right in orbit, thereby realizes autodegauss, does not need manually to carry out demagnetization, uses convenient.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the structure chart of an embodiment of magnet board of the present utility model;

Fig. 2 is the structural representation of an embodiment of the blackboard body of magnet board of the present utility model;

The schematic diagram that coordinates between demagnetization blackboard roller and the framework upper rail of Fig. 3 for reflection magnet board of the present utility model.

The specific embodiment

Below with reference to accompanying drawing, the utility model is elaborated.

Referring to Fig. 1, when specifically implementing for the structural representation of an embodiment of a kind of magnet board of the present utility model, this magnet board of the present embodiment comprises blackboard body 11, the framework 12 that is rectangle and magnetic pen (not shown).referring to Fig. 2 and Fig. 3, in the present embodiment, this blackboard body 11 comprises matrix 111, plastic cement 112, clipboard 113, and be evenly distributed on magnetic blow out coating 114 on this plastic cement 112, this clipboard 113, magnetic blow out coating 114, plastic cement 112 and matrix 11 stack gradually from left to right and are fixed on framework 12, and the both sides up and down of framework 12 are respectively equipped with guide rail 121, be provided with between these framework 12 upper/lower guides 121 and can wipe piece 122 along the demagnetization that this guide rail 121 moves left and right, in the present embodiment, this demagnetization is wiped piece and is separately installed with roller 123 in two ends Shang Xia 122, this roller 123 matches with this guide rail 121, and in the present embodiment, the centre of this demagnetization wiping piece 122 is provided with Handheld Division 124.

The magnet board of the present embodiment is by arranging magnetic blow out coating 114 between matrix 111 and clipboard 113, when needs are write, by magnetic pen, magnetic is magnetized and form word on clipboard 113, when the needs erasing out handwriting, directly wipe piece 122 by demagnetization magnetic is carried out demagnetization, namely the residual magnetism on the demagnetization magnetic, make magnetic get back to again on matrix, simple clean in this process, avoided the impact of dust on health.

In another specific embodiment, magnet board is identical with the magnet board structure of above-described embodiment, identical parts adopt identical Reference numeral, different is on this demagnetization wiping piece 122, Handheld Division 124 not to be set in the present embodiment, wipe but drive this demagnetization in being used for above framework 12 drive motors that piece 122 moves left and right between guide rail 121, the output shaft of this drive motors is connected with the roller 123 that piece 122 1 ends are wiped in demagnetization.Drive this demagnetization wiping piece 122 by this drive motors in the present embodiment and move left and right between the guide rail 121 of framework 12, thereby realize autodegauss, do not need manually to carry out demagnetization and come erasing out handwriting, use convenient.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
