Abstract
An anatomizable globe that allows teachers and students to dissect the globe's globe body portion. The sphere of the existing globe is divided into four quarter spheres by coils along the equator, the west longitude 20 degrees and the east longitude 160 degrees, a plurality of positioning combination points are respectively made on the semi-circular surfaces of the quarter spheres by utilizing the principle that permanent magnets attract each other in opposite directions, and the quarter spheres can be connected into a sphere by utilizing the positioning combination points in sequence. And drawing a legend for representing geological structures such as the crust, the mantle, the core and the like on the semi-circle surface of the quarter sphere. People can use the globe to complete various teaching functions of the existing globe, and teachers and students can conveniently know the division of the globe on the earth and the geological structure inside the earth.
Description
Affiliated technical field
The utility model is the instrument about geographical teaching, especially can dissect this terrestrial globe for teachers and students in teaching process, so that allow teachers and students understand the division of earth episphere and architectonic a kind of instruments used for education of earth interior.
Background technology
Present employed terrestrial globe map making and making on a spheroid all in the geographical teaching.People can understand the geographical object of earth surface by the legend of watching globe surface, and people can come to give easily a certain point location of earth surface according to graticules.People can understand the rotation of the earth by the spheroid on rotating the globe, and people can understand different time zone difference constantly on the earth according to meridian circle.But this terrestrial globe is unfavorable for Faculty and Students and is used to demonstrate the division in east, the Western Hemisphere and south, the Northern Hemisphere on the earth, is unfavorable for that also classmates understand the problems such as tectonic structure of earth interior in learning process.
Summary of the invention
In teaching process, can not demonstrate the division of earth episphere and the problems such as internal structure of the earth in order to overcome existing terrestrial globe, the utility model provides a kind of terrestrial globe of dissecting, it not only has every instructional function of existing terrestrial globe, but also has the division of demonstrating earth east, the Western Hemisphere, the division in south, the Northern Hemisphere, the architectonic instructional function of demonstration earth interior.But its anatomical just is meant that it can separately also can easily combine the spheroid of existing terrestrial globe part easily.
The technical scheme that its technical matters that solves the utility model adopts is: on the base of terrestrial globe meridian circle is installed, there are south, the two poles of the earth, north of the terrestrial globe earth's axis at the two ends of meridian circle, and the spheroid of terrestrial globe partly is installed on the south, the two poles of the earth, north of the earth's axis.The spheroid of terrestrial globe partly is along the equator and west longitude 20 is spent and east longitude 160 is spent four 1/4th spheroids that coils are divided into, the various legends that are used for representing the earth surface geographical object are arranged on 1/4th spheres of 1/4th spheroids, the locating combination point that useful permanent magnet is made respectively on the semi circular surface of 1/4th spheroids, these locating combination points are to utilize the magnet principle that there is a natural attraction between the sexes to make.The legend that is used for representing geologic structures such as the earth's crust, earth mantle, the earth's core that also useful different colours is drawn on the semi circular surface of 1/4th spheroids.People utilize locating combination point can connect into a spheroid to four 1/4th spheroids in order, this spheroid is installed on the south, the two poles of the earth, north of the globe base earth's axis can satisfy existing every instructional function of globe traditionally, this spheroid is taken off and can be dissected for teachers and students from base, make things convenient for teacher, student to understand the division of earth episphere and the tectonic structure of earth interior.
The beneficial effects of the utility model are: the terrestrial globe that can dissect is compared with existing traditional terrestrial globe, its advantage and good effect show that mainly it has Duoed some instructional functions than existing terrestrial globe, the ability of probing into that it can allow the student cultivate the student with a series of practical activities such as operations by experiment, allow the student in practical activity, learn and understand on the earth south, the Northern Hemisphere, east, the division in the Western Hemisphere and a series of problems such as tectonic structure of the earth.
Description of drawings
Below in conjunction with accompanying drawing and enforcement Lee the utility model is described further.
Fig. 1 is the structural representation of the terrestrial globe that can dissect.
1. bases among the figure, 2. earth's axis South Pole, 3. gerontogeous the Southern Hemisphere part, 4. equator, 5. equatorial plane and the interfacial intersecting lens of thing hemisphere, the 6. earth's axis arctic, 7. meridian circle, 8. the Northern Hemisphere part in the Western Hemisphere, 9. west longitude 20 degree warps, the 10. the Southern Hemisphere part in the Western Hemisphere, 11. locating combination points, 12. gerontogeous Northern Hemisphere part, 13. east longitudes, 160 degree warps.
Embodiment
In Fig. 1, the arctic (6) that meridian circle (7) connects the earth's axis also links to each other with base (1) with the earth's axis South Pole (2), the gerontogeous the Southern Hemisphere part (3) and the gerontogeous Northern Hemisphere part (12) of globe sphere part connect into the Eastern hemisphere by locating combination point (11), the Northern Hemisphere part (8) in the Western Hemisphere and the Southern Hemisphere part (10) in the Western Hemisphere connect into the Western Hemisphere by locating combination point (11), and the Eastern hemisphere and the Western Hemisphere connect on the South Pole and the arctic that complete spheroid is installed in the earth's axis by locating combination point (11).The locating combination point (11) that connects each 1/4th spheroid makes with permanent magnet, it is evenly distributed on the semi circular surface of each 1/4th spheroid, the surface that magnet appears is equal with the semi circular surface of 1/4th spheroids, to guarantee that adjacent semi circular surface does not have the slit when connecting under the effect of anchor point, be painted with the various geographical objects of various legends on 1/4th spheres of each 1/4th spheroid in order to the expression earth surface, useful different colours is drawn on the semi circular surface of each 1/4th spheroid is used for representing the architectonic legend of earth interior, these locating combination points can satisfy the student and be used to dissect this terrestrial globe, and the tectonic structure legend can be told the tectonic structure of student's earth interior intuitively.
Claims (3)
1. the terrestrial globe that can dissect, the spheroid part of terrestrial globe can be by east, the Western Hemisphere, south, the Northern Hemisphere freely separate and is combined to one smoothly, it is characterized in that: the spheroid of terrestrial globe partly is to be combined into by spend four 1/4th spheroids that coils are divided into along equator and west longitude 20 degree and east longitude 160.
2. terrestrial globe of dissecting according to claim 1, it is characterized in that: the locating combination point that useful permanent magnet makes on the semi circular surface of 1/4th spheroids of composition globe sphere part, and the legend in order to the different geologic structure of expression earth interior of useful different colours drafting.
3. terrestrial globe of dissecting according to claim 2 is characterized in that: the locating combination point on 1/4th spheroid semi circular surfaces can be hidden within semi circular surface, and also can keep equal and on semi circular surface, reveal with semi circular surface,
