Abstract

The utility model belongs to a geography demonstration teaching aid, which is mainly composed of a base, a latitude arc, a spring earth axis, and a drift continental plate. The key point lies in that the inner of a globe body is provided with a spring earth axis device which can eject a magnetic globe split block; the inner wall of the globe body is drawn with the structural map of ring layer, and a globe surface is drawn with distribution maps of global volcanoes and seismic belts and the graphic of landforms of seven continents. A plurality of drifty continental plates are absorbed on the globe surface, which can demonstrate continental drifting, vividly indicate drift states of six plates on the earth, indicate distribution conditions of global volcanoes and seismic belts and the distribution of landforms, mountains, and rivers of all continents on the surface of the land, and can visualize the ring layer structure of the inner of the earth. The utility model is a new geography demonstration teaching aid for geographical teaching of urban and rural schools in China at present.

Description

Multi-function globe for demonstration purpose

The utility model belongs to a kind of geographical demonstration teaching aid.

The terrestrial globe that at present in China vast town and country school, is used to impart knowledge to students, above only draw two kinds of administrative division figure or topomap arranged, content is single, do not demonstrate the drift situation of earth interior ring layer structure and continental-bearing plate, students is difficult to understand geographical knowledge, and this old-fashioned teaching aid can not adapt to current teaching needs far away.

The purpose of this utility model provides a kind of improved, and spheroid can be split into the lobe piece, can demonstrate the multi-functional demonstration terrestrial globe of continental-bearing plate drift on the sphere.

The utility model mainly contains base (1), latitude arc bow (2), the spring earth's axis (3), start button (4), spring leaf (5), spheroid (6), spheroid subdivision piece (7), the continental-bearing plate (8) that can drift about formation, key is that the spring earth's axis (3) is hollow tubular (metal or plastics), in spheroid 1/2 first half opening, spring leaf (5) is housed, connect the top, start button (4) can eject magnetic spheres subdivision piece; Spheroid (6) is made for magnetic material, but the spheroid subdivision is a lobe piece (7) such as 1/2,1/4,1/8, and can glue and inhale the lobe piece that cuts, spheroid subdivision inwall is drawn inner ring layer structural map, earth ' s interior structure directly perceived and internal structure form, as: the earth's crust (lithosphere), upper mantle (asthenosphere), lower mantle (solid), the outer earth's core (liquid), inner core (solid) and thickness thereof, temperature, density etc.; Spheroid (6) surface rendering has the volcanic earthquake distribution plan, and wherein there is the different blue colour specification of the depth ocean, and draws the exclusive earth, spherical stretch-out views such as submarine ridge, trench, land, seven continents; On each continent profile of spheroid (6), be adsorbed with the magnetic that matches with each the continent landform continental-bearing plate (8) (6 plots of continental-bearing plates) that can drift about, the slip of can drifting about arbitrarily.

The invention has the advantages that teacher can do following demonstration in teaching:

1, demonstration drift of continents, the demonstration of can drifting about arbitrarily on sphere of continental block on the terrestrial globe can make the intuitively ancient continent of earth lastblock before more than 200,000,000 years of student, through ground drift in 1 years, develop and form present seven continents gradually, and among drifting about now, developing.

2, it can vivo demonstrate six macroplates on the earth, the trench that forms owing to drift, collision, underriding, lifting, mountain region, plateau etc.

3, it can demonstrate global volcano, seismic zone be scattered in because of, and to demonstrate all be area along plate intersection crustal unrest.

4, this terrestrial globe is equipped with on earth top and releases the button, and presses button and the spheroid subdivision of terrestrial globe can be opened.

5, but the spheroid subdivision is 1/2,1/4,1/8 lobe piece, and its subdivision inwall is painted with inner ring layer structure and external morphology figure, is the requisite a kind of novel geographical demonstration teaching aid in present China vast town and country school geographical teaching aspect.

Description of drawings:

Fig. 1, multi-functional demonstration terrestrial globe synoptic diagram;

Fig. 2, multi-functional demonstration terrestrial globe (continental-bearing plate drift) synoptic diagram;

(1) base, (2) latitude arc bow, (3) spring earth's axis, (4) start button, (5) spring leaf (6) spheroid, (7) spheroid subdivision piece, (8) continental-bearing plate that can drift about.

Embodiment:

Base (1) can be designed to all styles of as animal, personage etc., the latitude arc bow made from metal or plastics (2) can be installed on the base, in the middle of base and latitude arc bow, magnetic spheres is installed, but the spheroid subdivision is 1/2,1/4,1/8 magnetic lobe piece, spheroid subdivision inwall is drawn inner ring layer structural map, the spring earth's axis (3) is the hollow tubular made from metal or plastics, be installed in spheroid 1/2 first half opening, built-in spring sheet (5) is gone up dress start button (4) and is connected the top, start button (4) can eject magnetic spheres subdivision piece (7) continental-bearing plate (8) that can drift about and use magnetic material, can make according to the figure in 7 continents, and can be adsorbed on the magnetic spheres, can print the volcano on the sphere, the seismic zone distribution plan, the ocean, submarine ridge, the spherical stretch-out view of trench.

Can be according to using the object needs, the spheroid size specification is: small-sized sphere diameter is 18～21cm, is applicable to student and family's children's intelligence exploitation.Medium-sized sphere diameter is 32～45cm, is applicable to classroom instruction usefulness, and the large-scale spherical diameter is 50～100cm, is applicable to that office, scientific research department use.

Claims

1, a kind of multi-functional demonstration terrestrial globe is made of base, latitude arc bow, the earth's axis, spheroid, it is characterized in that:

A, the spring earth's axis (3) are hollow tubulars, at spheroid 1/2 first half opening, in spring leaf (5) is housed, connect top start button (4), can eject magnetic spheres subdivision piece;

B, magnetic spheres (6) but subdivision is 1/2,1/4,1/8 lobe piece (7), and can adsorb the lobe piece that cuts, the subdivision inwall is drawn earth interior ring layer structure and ring layer constitutional diagram thereof;
