Abstract
The utility model discloses a magnetic teaching demonstration board, which consists of a framework (1) and an internal magnetic blackboard (2). The internal magnetic blackboard (2) is fixedly arrangedin the framework (1), the inside of the internal magnetic blackboard (2) is embedded with a plurality of permanent magnets arranged neatly in sequence. The magnetic teaching demonstration board is characterized in that the left frame, the right frame and the lower frame of the framework (1) are fixedly provided with a clamping rod (3) through rotating shafts, the mobile end of the clamping rod (3) extends towards the central position of the internal magnetic blackboard (2) and contacts with the surface thereof, and a teaching picture (4) is arranged on the surface of the internal magnetic blackboard (2). The utility model has the advantages of simple structure and convenient use, and can be used as a blackboard for writing or as a demonstration board for demonstrating a prepared teachingpicture, thereby saving the teaching time and improving the teaching quality.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of magnetic teaching demonstrating board.
Background technology
The existing teaching aid of China is of a great variety, wherein the function ratio of the magnetic education demonstrator that often uses is more single, the magnetic education demonstrator of existing teaching demonstration picture only can be used for demonstrating the teaching picture of irony, owing to can not hold general teaching picture, so this utensil can not be demonstrated general teaching picture, when demonstrating general teaching picture, can only adopt utensil in addition, and existing magnetic education demonstrator can not be not only when writing blackboard but also can the teaching demonstration picture, use extremely inconvenience, be unfavorable for promoting the use of.
In addition, for the teacher of economic management class when giving lessons, because the teacher of this subject generally comes the demand of the various business decision of analysis of system logic by coordinate, produce, cost and market etc., so generally not be used in and write a large amount of contents of courses on the blackboard, just can well demonstrate the knowledge of knowing institute's GPRS by simple reference axis, but all there is not coordinate on existing blackboard or the demonstrator, and the teacher of economic management class uses more frequent to reference axis when giving lessons, so need to repaint after frequent the wiping, so not only reduce efficiency of teaching, and increased teacher's working strength.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and can write and the teaching picture of making in advance can be placed on the magnetic teaching demonstrating board on the demonstration device on same blackboard.
In order to reach above purpose, the technical scheme that the utility model adopted is: this magnetic teaching demonstrating board, constitute by framework and internal magnetization blackboard, internal magnetization blackboard in framework, fixing, in the internal magnetization blackboard, be inlaid with the permanent magnet of polylith arrangement in good order, it is characterized in that on the frame of left and right, the downside of framework by rotating shaft fixing on supporting rod, the movable end of supporting rod contacts to the extension of the centre of internal magnetization blackboard and with its surface, and teaching picture is located at the surface of internal magnetization blackboard.
Described supporting rod is a telescopic structure.
The top of described framework is provided with and is linked with.
Described internal magnetization blackboard is provided with soft stripe shape magnetic and pastes axis of abscissas and the axis of ordinates of making.
The beneficial effects of the utility model are: can it be adsorbed on the internal magnetization blackboard demonstrate so that the teaching picture of irony is with in absorption by the internal magnetization blackboard, and easy to operate; On framework, be hinged with the supporting rod that is used for the clamping object, and an end of supporting rod contacts to the extension of the centre of described internal magnetization blackboard and with it, can clamp general teaching picture by this structure, and more firm being fixed on the internal magnetization blackboard of the teaching picture that can make irony, prevent that teaching picture from coming off, and improves the quality of teaching in the teaching process; In addition, the utility model adopts soft stripe shape magnetic to paste axis of abscissas and the axis of ordinates of making, make axis of abscissas and axis of ordinates all can need and paste arbitrarily with lecture contents, this helps accelerating demonstration operation in the teaching process and also helps and make the knowledge set forth more clear.This magnetic teaching demonstrating board, simple in structure, easy to use, can on same blackboard, can write and the teaching picture of making in advance can be placed on the demonstration board and demonstrate, save instructional blocks of time, improve the quality of teaching.
Description of drawings
Fig. 1 looks schematic diagram for structure master of the present utility model.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.This magnetic teaching demonstrating board, constitute by framework 1 and internal magnetization blackboard 2, internal magnetization blackboard 2 in framework 1, fixing, in internal magnetization blackboard 2, be inlaid with the permanent magnet of polylith arrangement in good order, the surface of internal magnetization blackboard 2 is made smooth plane and is painted black, make it to form the black magnetic plate that to write with chalk, it is characterized in that a left side at framework 1, right, fix upward supporting rod 3 by rotating shaft on the frame of downside, the movable end of supporting rod 3 contacts to the extension of the centre of internal magnetization blackboard 2 and with its surface, teaching picture 4 is located at the surface of internal magnetization blackboard 2, teaching picture 4 can be made general papery picture or irony picture, papery picture can come clamping to demonstrate by supporting rod 3, and can be adsorbed on the surface of internal magnetization blackboard 2, demonstrates by the irony picture, simultaneously, the also available chalk in the surface of internal magnetization blackboard 2 is write, when general blackboard is used.
Described supporting rod 3 is a telescopic structure, can regulate the teaching picture 4 that supporting rod 3 comes the different sizes of clamping so as required, uses fairly simple, convenient.
The top of described framework 1 is provided with and is linked with 7, imparts knowledge to students with convenient moving.
Described internal magnetization blackboard 2 is provided with soft stripe shape magnetic and pastes axis of abscissas 5 and the axis of ordinates of making 6, they can be adsorbed on the internal magnetization blackboard 2 like this, axis of abscissas 5 and axis of ordinates 6 are orthogonal reference axis, can be convenient to improve efficiency of teaching so directly by the next analysis theories knowledge of the reference axis on the internal magnetization blackboard 2 like this to student's demonstration and system logic; In addition, axis of abscissas 5 and axis of ordinates 6 all can need and paste arbitrarily with lecture contents, and this helps accelerating demonstration operation in the teaching process and also helps and make the knowledge set forth more clear.
Claims (2)
1, a kind of magnetic teaching demonstrating board, constitute by framework (1) and internal magnetization blackboard (2), the fixing internal magnetization blackboard (2) of going up in framework (1), in internal magnetization blackboard (2), be inlaid with the permanent magnet of polylith arrangement in good order, it is characterized in that on the frame of left and right, the downside of framework (1) by the fixing supporting rod (3) of going up of rotating shaft, the movable end of supporting rod (3) contacts to the extension of the centre of internal magnetization blackboard (2) and with its surface, and teaching picture (4) is located at the surface of internal magnetization blackboard (2).
2, magnetic teaching demonstrating board according to claim 1 is characterized in that described supporting rod (3) is a telescopic structure; The top of described framework (1) is provided with and is linked with (7).
