Abstract
The utility model relates to a magnetic combined globe which comprises a globe body and a base, wherein the globe body is divided into three parts which are a hemisphere, a three eights sphere, and a one eight sphere, and the spheres of the three parts are mutually attached together by a magnet fixed on the spheres. The hemisphere and the base are mutually attached together by the magnet fixed on the hemisphere and the base. The utility model has the advantages of simple structure, convenient disassembly and multifunction. The utility model can visually demonstrate the inner and the outer structures of the earth, and the utility model is favorable for the teaching of primary and secondary schools.
Description
The utility model relates to a kind of instruments used for education.
Existing terrestrial globe be mainly used in earth surface on the demonstration earth structure, and day alternates with night etc., its shortcoming is the demonstration that lacks earth ' s internal structure, is unfavorable for teaching.
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of simple in structure, magnetic of being more suitable for demonstrating earth ' s internal structure globe in combination is provided.
The purpose of this utility model reaches like this: the utility model includes geoid and base, geoid is divided into three parts, hemisphere, 3/8ths spheroids and eighth ball body, be attached together mutually by the magnet that is fixed on the spheroid between the three part spheroids, also be attached together mutually between hemisphere and the base by the magnet that is fixed on hemisphere and the base.
Three part spherome surfaces are combined into complete earth surface, indicate the internal structure of the earth on the cutting plane of three part spheroids, the earth's crust, earth mantle, the earth's core.
The utility model is simple in structure, convenient disassembly, and diverse in function can be demonstrated earth interior and outside structure intuitively, helps middle and primary schools' teaching.
Do further narration below in conjunction with accompanying drawing:
Accompanying drawing is the utility model structural representation.
Among the figure: 1, base, 2,3/8ths spheroids, 3, the eighth ball body, 4, hemisphere, 5,6,7,8,9,10, magnet.
Hemisphere 4 and base 1 are equipped with pair of magnet 5,6 at the place of being in contact with one another, and magnet 5,6 polarity are provided with on the contrary. Eighth ball body 3 and 3/8ths spheroids 2 are equipped with pair of magnet 8,7 at the place of being in contact with one another, eighth ball body 3 and hemisphere 4 are equipped with pair of magnet 9,10 at the place of being in contact with one another, 3/8ths spheroids 2 and hemisphere 4 also are equipped with pair of magnet at the place of being in contact with one another, and every pair of magnet all is that polarity is provided with on the contrary.
