Abstract
The utility model discloses a contour line demonstrating device, belongs to the field of geography teaching instruments, and structurally comprises a support and side boards. The cross section of the support is U-shaped, and inner sides of the two side boards of the support are provided with a plurality of parallel clamping grooves. The surface of a transparent board is provided with contour lines, and the transparent board is matched with the clamping groove in sliding mode. Compared with the prior art, the contour line demonstrating device has the advantages of being reasonable in design, simple in structure, easy to process, convenient to use and the like, can demonstrate contour lines in three-dimensional and visual mode, and effectively improves teaching quality.
Description
Technical field
The utility model relates to the geographical teaching instrument field, specifically the level line demonstration device.
Background technology
In the middle school geography class teaching material, though the content of relevant mountain region level line landform circle knowledge is few, but the big difficult point in the teaching.Because students ' age is less, open-air knowledge is poor relatively, and the space imagining ability deficiency is in the face of teaching material, they can not be mapped the form of expression and the actual landform of basic landform on circle, to such an extent as to they can not grasp this part knowledge in for a long time even all the time.Above-mentioned phenomenon is lectured all existence to some extent when lecturing correlated curriculum in the subjects such as isotherm, isobar bending and temperature, gas pressure distribution relation at first, senior geography teaching.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provide a kind of simple in structure, be easy to process, level line demonstration device easy to use.
The technical scheme that its technical matters that solves the utility model adopts is: this level line demonstration device comprises support and side plate, the cross section of support is " U " shape, two side plate inboards of support have many draw-in grooves that are parallel to each other, and isocontour transparent panel is decorated with on the surface and draw-in groove is slidingly matched.
Described draw-in groove opening part mark has height value.
Level line demonstration device of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as easy to use, can solid demonstrate the line of ascending a height intuitively, effectively raise quality of instruction.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of level line demonstration device.
Among the figure: 1, support, 2, side plate, 3, draw-in groove, 4, transparent panel, 5, level line, 6, height value.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Level line demonstration device of the present utility model, its structure comprises support 1 and side plate 2, and the cross section of support 1 is " U " shape, and two side plate 2 inboards of support 1 have many draw-in grooves that are parallel to each other 3, the transparent panel 4 that level line 5 is decorated with on the surface is slidingly matched with draw-in groove 3, and draw-in groove 3 opening parts mark has height value 6.
In the time of need demonstrating to the student, can be according to the transparent panel 4 that inserts varying number on the support 1 that do not coexist of Terrain Elevation, the student can see height change intuitively from support 1 side, thereby can accurately grasp relevant knowledge.
Its processing and fabricating of level line demonstration device of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
