Abstract

The utility model discloses a demonstration device for geography teaching. The demonstration device comprises an upper lifting frame, a sphere, a cambered supporting rod, an upper sliding block, batteries, lighting switches, lamp bulbs, a lower sliding block, a bottom bracket, a rotary vertical shaft and a base, wherein the base is a grounding piece; the rotary vertical shaft is arranged in the center of the upper surface of the base; the upper end of the rotary vertical shaft is connected with the bottom bracket; the cambered supporting rod is arranged on one side of the bottom bracket; and the lower section of the cambered supporting rod is connected with the bottom bracket, and the upper section of the cambered supporting rod is connected with the upper lifting frame. The lower sliding block is inserted into the lower section of the cambered supporting rod; the upper sliding block is inserted into the upper section of the cambered supporting rod; the upper sliding block and the lower sliding block are provided with the batteries serving as power supplies; the lamp bulbs for lighting are arranged on the inner side surfaces of the upper sliding block and the lower sliding block; and the lighting switches are arranged on the outer side surfaces of the upper sliding block and the lower sliding block. The whole demonstration device has a simple structure, is convenient to operate and use and high in stability, and can help students to understand and master the change law of the sun to perpendicular incidence points caused by the revolution of the earth.

Description

A kind of geographical teaching apparatus for demonstrating

Technical field:

The utility model relates to the geographical teaching teaching aid, relates in particular to a kind of geographical teaching apparatus for demonstrating.

Background technology:

In the geographical teaching process, some content can be explained by wall chart, some content is then more abstract, revolution such as the area forms the variation of the sun to point of vertical, to a certain degree can help the student to understand in diagram on the textbook and teacher's the explanation, also can not reflect simultaneously actual geographical knowledge or the content that phenomenon embodied to a certain extent well, especially at the teaching aid deficiency of this knowledge point, so also just can not demonstrate comparatively intuitively, to student's understanding and grasp unfavorable.

The utility model content:

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of geographical teaching apparatus for demonstrating is provided, and can help the student to understand and grasp the sun that revolution of earth the causes Changing Pattern to point of vertical preferably effectively.

A kind of geographical teaching apparatus for demonstrating described in the utility model includes over sling, spheroid, arc support bar, top shoe, battery, light switch, bulb, sliding block, bottom bracket, rotating vertical shaft and pedestal and forms.Pedestal is an earthing member of the present utility model, the position at center on pedestal, be provided with rotating vertical shaft, the upper end of rotating vertical shaft is connected with bottom bracket, one side of bottom bracket, be provided with the arc support bar, the hypomere of arc support bar is connected with bottom bracket, and the epimere of arc support bar is connected with over sling.On the hypomere of arc support bar, be provided with sliding block with the form that penetrates, on the epimere of arc support bar, be provided with top shoe with the form that penetrates, all be provided with the battery that uses as power supply on top shoe and the sliding block, on the medial surface of top shoe and sliding block, all be provided with illuminating bulb, on lateral surface, all be provided with light switch.Below over sling, be provided with the central shaft of using to lower support, on bottom bracket, be provided with the central shaft of using to upper support, between two central shafts, be connected with spheroid.

A kind of geographical teaching apparatus for demonstrating described in the utility model, one-piece construction is simple, and is easy for operation, good stability, reliability height.Use a kind of geographical teaching apparatus for demonstrating described in the utility model, can help the student to understand and grasp the sun that revolution of earth causes Changing Pattern preferably effectively point of vertical.
