Abstract
The utility model provides a terminator line and night hemisphere demonstration instrument for geographical teaching. The demonstration instrument structurally comprises an earth model fixed with a connecting frame, wherein the connecting frame is connected with a base through a connecting rod; a hemispherical baffle is fixed outside the earth model and shields half of the earth model; a lighting tube is arranged on the outer wall of the hemispherical baffle; and a lighting source is installed at the end part of the lighting tube. According to the utility model, compared with the prior art, the demonstration instrument has the characteristics of reasonable design, simple structure, convenience in use, complete functions, simple and vivid simulation demonstration and the like, can improve the studying interest of students and create convenient conditions for teaching.
Description
Technical field
The utility model relates to a kind of teaching aid, and a kind of specifically geographical teaching easy to use is with terminator and night hemisphere demonstrator.
Background technology
Terrestrial globe is a kind of common education stationery.Commercially available terrestrial globe comprises: base, framework and earth model, and base is provided with framework, and framework is used for fixing earth model; Framework is connected with base through a column; Framework is an arc-shaped structure, and framework is connected with earth model through a rotating shaft, and the centre of sphere of earth model is passed in rotating shaft.Earth model can rotate around the axis, the imitation earth rotation.But existing function of globe is single, is merely able to check more intuitively the geographic position, does not have other auxiliary functions, especially can't intuitively embody for changing round the clock, can not satisfy teachers and students and use needs.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, provides a kind of geographical teaching easy to use with terminator and night hemisphere demonstrator.
The technical scheme of the utility model realizes by following mode; This geographical teaching is with terminator and night hemisphere demonstrator, and its structure comprises that link is connected with base through connecting link through the fixing earth model of link; The fixing hemisphere block body in the said earth model outside; This hemisphere block body shelters from earth model half, and a fluorescent tube is set on the outer wall of hemisphere block body, and the end of fluorescent tube is equipped with lighting source.
Said connecting link is divided into up and down two joints and links together through telescopic joint.
Said base is a sucker base.
Said fluorescent tube is a Collapsible telescopic fluorescent tube.
The beneficial effect that the utility model is compared with prior art produced is:
The geographical teaching of the utility model with terminator and night hemisphere demonstrator have simple in structure, easy to use, characteristics such as be skillfully constructed; Its structure is through the cooperation of hemisphere block body and lighting source; Increase illumination to earth model on the one hand, can shine the earth by simulated solar on the other hand, can demonstrate the variation of terminator and night hemisphere more intuitively; Thereby improve the interest of student's studying the geography, the teaching condition that facilitates.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Mark in the accompanying drawing is represented respectively:
1, link, 2, connecting link, 3, base, 4, telescopic joint, 5, earth model, 6, the hemisphere block body, 7, lighting source, 8, fluorescent tube.
Embodiment
Below in conjunction with accompanying drawing the geographical teaching of the utility model is done following the detailed description with terminator and night hemisphere demonstrator.
Shown in accompanying drawing 1; This geographical teaching is with terminator and night hemisphere demonstrator, and its structure comprises the earth model of fixing through link 15, and link 1 is connected with base 3 through connecting link 2; A hemisphere block body 6 is fixed in said earth model 5 outsides; This hemisphere block body 6 shelters from earth model 5 half, and a fluorescent tube 8 is set on the outer wall of hemisphere block body 6, and the end of fluorescent tube 8 is equipped with lighting source 7.
Said connecting link 2 is divided into up and down two joints and links together through telescopic joint 4, and the teacher can regulate the length of connecting link 2 in use according to actual conditions; Said base 3 is a sucker base, thereby this terrestrial globe secure is lived; Said fluorescent tube 8 is a Collapsible telescopic fluorescent tube, makes things convenient for the teacher to regulate the irradiating angle of lighting source 7.
