Abstract
The utility model discloses a mathematic chart circulatory demonstration board which belongs to a manual education demonstration appliance or chart which is connected by magnets and provided with symbols and graph components, in particular relating to a teaching appliance for a histogram and a line chart in mathematics or a general data periodical circulatory demonstration board, mainly comprising a metallic material substrate, a chart information layer and a magnetic demonstration layer, wherein the magnetic demonstration layer mainly comprises cylindrical line chart node magnets and histogram magnetic display bars. When the teaching appliance for the histogram and the line chart in mathematics or the general data periodical circulatory demonstration board is used, data variation rules are shown on the chart information layer through positions of the line chart node magnets and lengths of the histogram magnetic display bars in reference to the data quantity of a horizontal coordinate and a vertical coordinate, which is visual and direct-viewing, thereby the chart data rules can be repeatedly shown by means of changing the node magnets and the magnetic display bars according to different data.
Description
Technical field
The utility model belongs to uses the manual education demonstration equipment or the chart that have symbol, graphics part, particularly mathematics chart circulation demonstration board that magnet connects.
Background technology
General teacher at different information, need draw different broken line graphs and histogram repeatedly on blackboard when teaching mathematics form information graphic to the student, time-consuming like this, not directly perceived.In addition in some enterprises and institutions, usually will add up and each month of show-and-tell or the producing and selling of each year, the Changing Pattern of workload, and the information fundamental quantity all is identical, but needs the whole Graphic Panel that changes, inconvenient, dumb like this, relatively waste.
The utility model content
In order to overcome the existing whole deficiency of drawing or changing data drawing list, the utility model provides a kind of mathematics chart circulation demonstration board, and this mathematics chart circulation demonstration board can circulate and recycle.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of mathematics chart circulation demonstration board, comprise the metal material substrate, the chart-information layer, described metal material upper surface of base plate has the chart-information layer that shows mathematics broken line graph or histogram coordinate amount, adheres to the magnetic presentation layer that has broken line graph node magnetic patch or histogram magnetic show bar on described chart-information layer.
Above-mentioned mathematics chart circulation demonstration board, described broken line graph node magnetic patch is a cylindrical shape, and there is through wires hole in described broken line graph node magnetic patch central authorities, and the fine rule of expression mathematics broken line graph Changing Pattern passes from through wires hole.
The beneficial effects of the utility model are: the broken line graph node magnetic patch or the histogram magnetic show bar that utilize cylindrical shape, rely on the metal material substrate, be adsorbed on expression data variation rule on the chart-information layer that is painted with horizontal ordinate and ordinate data volume, visual in image like this, can only change node magnetic patch and magnetic show bar according to different data, show the chart data rule repeatedly.Mathematics chart circulation demonstration board each month of show-and-tell or the producing and selling of each year repeatedly in addition, the Changing Pattern of workload do not need whole change Graphic Panel, easy to use, flexible saving.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Fig. 2 is the structure cut-open view of Fig. 1,
Fig. 3 is the structural drawing of broken line graph node magnetic patch,
Among the figure, 1. metal material substrate, 2. chart-information layer, 3. magnetic presentation layer, 4. broken line graph node magnetic patch, 5. histogram magnetic show bar, 6. fine rule, 7. through wires hole
Embodiment
Embodiment of the present utility model is, as shown in the figure:
Embodiment 1, a kind of mathematics chart circulation demonstration board, comprise metal material substrate 1, chart-information layer 2, described metal material substrate 1 upper surface has the chart-information layer 2 that shows mathematics broken line graph or histogram coordinate amount, on described chart-information layer 2, adhere to the magnetic presentation layer 3 that has broken line graph node magnetic patch 4 or histogram magnetic show bar 5, described broken line graph node magnetic patch 4 is cylindrical shapes, there is through wires hole 7 in described broken line graph node magnetic patch 4 central authorities, and the fine rule 6 of expression mathematics broken line graph Changing Pattern passes from through wires hole 7.
Claims (2)
