Abstract

The invention belongs to teaching aid technical field, it is related to a kind of geographical teaching aid, specifically a kind of plastics yellow River model.The plastics yellow River model, it is a thermoplastic molding duroplasts film shell, the plastics yellow River model produced using the technical program, because it is a pane shape, upper surface be colored printing and thermoplastic die forming Xi Gaodong is low, duroplasts film shell with Huanghe valley landform convex-concave feature, so it can more give expression to the geographical knowledge of the Yellow River than the picture and text on the geography textbook of dimensional printing goods visual pattern, teach through lively activities, classmates can be caused to learn the geographical interest in the Yellow River, it is also easier to understand, it is easy to learn easy to remember；It is easy to stack transport and carries, low cost easy to manufacture than sand table yellow River model light weight, is suitable as teaching aid popularization, and it is not only suitable for being used as geographical teaching instrument, and it is also adaptable as toy and uses, and the souvenir that it is more suitable for going sight-seeing the Yellow River is used.

Description

Plastics yellow River model

Technical field

The invention belongs to teaching aid technical field, it is related to a kind of geographical teaching aid, specifically a kind of plastics the Yellow River mould Type.

Background technology

The Bayan Har arteries and veins of Qinghai-Tibet Platean is risen in the Yellow River, and about 5464 kilometers of total length is Chinese second long river, the world the Six long rivers, flow through Qinghai, Sichuan, Gansu, Ningxia, the Inner Mongol, Shaanxi, Shanxi, Henan, nine, Shandong provinces and regions, most from West to East After flow into the Bohai Sea.The Yellow River is the cradle of the Chinese nation, is the mother river of the Chinese nation, and most people is all from geography textbook The geographical knowledge about the Yellow River is acquired, but geography textbook is the graph-text content of planographic, it is dry as dust, it is not visual in image, It is and the sand table yellow River model of solid is although visual in image but heavy, it is difficult to transport and carries, and high cost, it is impossible to as geography Teaching aid is used.

The content of the invention

Present invention solves the technical problem that be to provide a kind of carrying portable, low cost and visual in image geographical teaching work Tool plastics yellow River model.

The present invention adopts the technical scheme that, plastics yellow River model, and it is a thermoplastic molding duroplasts film shell, and it is special Levying is：The model is to enamel to be printed with the topographic map of the Huanghe valley in duroplasts film, and thermoplastic is molded out on the topographic map Kame-and-kettle topography model corresponding with Huanghe valley topographic map, have on the kame-and-kettle topography model Huanghe valley Qinghai-Tibet model, Mountain range model, lake model, loess plateau gully model, the Yellow River mainstream and branch flow model, North China Plain model, aboveground river mould Type and Bohai Sea sea level model, the upper surface of the plastics yellow River model is the low rectangle models of Xi Gaodong, the rectangle model Southern side face be a plane triangular in shape, the edge from the Sources of the Yellow River to estuary is printed on the triangle projective planum in southern side face River place name height above sea level chart, the north side face of the rectangle model is a plane triangular in shape, in the triangle in north side face The place name along the river from the Sources of the Yellow River to estuary is printed in plane apart from length chart, the west side face of the rectangle model is one The plane being rectangle, the length in each tributary being printed in the rectangular planes from the Sources of the Yellow River to estuary, flow and stream The chart of domain area, the upper surface of the plastics yellow River model, southern side face, west side face and north side face are a hard plastics for die forming Material film shell.

The plastics yellow River model produced using above technical scheme, because it is a pane shape, upper surface is colored Print and thermoplastic die forming Xi Gaodong is low, duroplasts film shell with Huanghe valley landform convex-concave feature, so it The geographical knowledge of the Yellow River can more be given expression to visual pattern than the picture and text on the geography textbook of dimensional printing goods, taught through lively activities, Classmates can be caused to learn the geographical interest in the Yellow River, be also easier to understand, it is easy to learn easy to remember；It than sand table yellow River model light weight, It is easy to stack transport and carries, low cost easy to manufacture, be suitable as teaching aid popularization, it is not only suitable for as geographical teaching instrument Use, it is also adaptable as toy and uses, the souvenir that it is more suitable for going sight-seeing the Yellow River is used.

In figure：1st, pane shape duroplasts film shell；1.1st, upper surface；1.2nd, southern side face；1.3rd, west side face.

Specific embodiment

In Fig. 1, the plastics yellow River model that the present invention is provided, it is a thermoplastic molding duroplasts film shell, its feature It is：The model is to enamel to be printed with the topographic map of the Huanghe valley in duroplasts film, on the topographic map thermoplastic be molded out with The corresponding kame-and-kettle topography model of Huanghe valley topographic map, there is Qinghai-Tibet model, the mountain of the Huanghe valley on the kame-and-kettle topography model Arteries and veins model, lake model, loess plateau gully model, the Yellow River mainstream and branch flow model, North China Plain model, aboveground river model And Bohai Sea sea level model, the upper surface (1.1) of the plastics yellow River model is the low rectangle models of Xi Gaodong, the rectangle mould The southern side face of type（1.2）It is a plane triangular in shape, in southern side face（1.2）Triangle projective planum on be printed on from the Sources of the Yellow River To the height above sea level chart of place name along the river of estuary, the north side face of the rectangle model is a plane triangular in shape, in north The place name along the river from the Sources of the Yellow River to estuary is printed on the triangle projective planum of side apart from length chart, the rectangle model West side face（1.3）It is a plane being rectangle, each from the Sources of the Yellow River to estuary is printed in the rectangular planes The chart of the length, flow and drainage area of stream, the upper surface of the plastics yellow River model（1.1）, southern side face（1.2）, west side face （1.3）It is a duroplasts film shell for die forming with north side face.
