Abstract
The utility model discloses a magnetic teaching presentation device which not only can attract, hang and store teaching pictures, but also can be used as a writing blackboard. The utility model comprises a frame (1), an inner magnetic type blackboard (2) and teaching pictures (3), wherein, a transparent slice (4) is arranged on the surface of the inner magnetic type blackboard (2) by the frame, the teaching pictures are stored between the transparent slice (4) and the inner magnetic type blackboard (2) by the frame, a plurality of orderly arranged permanent magnets (5) are enchased in the inner magnetic type blackboard (2), the bottom surface of the inner magnetic type blackboard (2) is a smooth black plane. By using the utility model, teachers can not only write on the same blackboard, but also attract or place the teaching pictures which are made in advance on the presentation device to present, thereby the teaching time is saved and the teaching quality is improved.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of magnetic education demonstrator.
Background technology
China's existing magnetic board of education function ratio is more single, only can be used for the teaching demonstration picture, can not be not only when writing blackboard but also can the teaching demonstration picture, use inconvenience, be unfavorable for promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of and can demonstrates and store teaching picture and can work as the education demonstrator that writing blackboard is used again.This magnetic education demonstrator is realized its purpose as follows: a transparent sheet is equipped with by framework in the surface at the internal magnetization blackboard, between the surface of transparent sheet and internal magnetization blackboard, store teaching picture is arranged, be inlaid with the permanent magnet of some arrangements in good order in the internal magnetization blackboard, the internal magnetization blackboard also can be made of a panel and a base plate, center fixed has the permanent magnet of some arrangements in good order, the bottom surface of internal magnetization blackboard is made smooth plane and painted black, make it to form the black magnetic plate that to write with chalk.By using the utility model magnetic education demonstrator, teacher can write on same blackboard and the teaching picture of making in advance can be sucked or be stored on the demonstration device and demonstrate, and saves instructional blocks of time, improves the quality of teaching.
Description of drawings
Fig. 1 is the structural representation of the utility model magnetic education demonstrator.
Fig. 2 is along A-A sectional structure schematic diagram in the utility model accompanying drawing 1.
The specific embodiment
As shown in drawings, framework 1 top made from light material is provided with suspension arrangement, the below is equipped with foot rest, surface at internal magnetization blackboard 2 is equiped with a transparent sheet 4 by framework 1, between the surface of transparent sheet 4 and internal magnetization blackboard 2, there are required teaching picture 3, the structure of internal magnetization blackboard 2 can adopt following dual mode: a, 130-150 block permanent magnet 5 is embedded in the thistle board in good orderly by the framework storage; B, 130-150 block permanent magnet 5 is fixed in two thin thistle boards in good orderly, leave a blank or filling with light material between magnet and the magnet, the bottom surface of internal magnetization blackboard 2 is made smooth plane and is painted black, makes it to form the black magnetic plate that can write with chalk.Teaching picture 3 can be made the picture of general picture or band irony, general picture can be clipped between the surface of transparent sheet 4 and internal magnetization blackboard 2 by framework and demonstrate, the picture of band irony can be adsorbed on the bottom surface of internal magnetization blackboard and demonstrates, the also available chalk in bottom surface of internal magnetization blackboard 2 is write simultaneously, when general blackboard is used.
Claims (2)
