Abstract

The utility model relates to a multifunctional tellurion for teaching geography, which comprises the following components: a base, a bracket and a sphere body. The sphere body is fixed by the bracket. A spring device box is provided between the bracket and the base. The spring device box is internally provided with a spring device. The spring handle of the spring device is projected from the box body of the spring device box. The output shaft of the spring device is connected with the sphere body. The spring handle is rotated. After the spring is tightened totally, the hand for tightening the spring is removed, and the sphere body can rotate slowly. The student can visually see the rotation process of the earth. The bracket is of a closed annular shape. A movable light source is sleeved on the bracket. The movable light source can slide in a longitudinal direction of the tellurion, thereby visually and vividly demonstrating day and night change, improving studying interest and understanding capability of the student. An abstract concept is changed to a concrete image, thereby providing more convenient teaching condition. Furthermore the multifunctional tellurion for teaching geography has the following advantages: simple structure, and high convenience in use.

Description

A kind of geographical teaching multifunctional globe

Technical field

The utility model relates to a kind of terrestrial globe, is applicable to geography teaching in middle school, specifically, relates to a kind of geographical teaching multifunctional globe, belongs to the technical field of teaching aid.

Background technology

Terrestrial globe is that people are for the ease of the understanding earth, copy the shape of the earth, dwindle according to certain ratio, be made into the model of the earth, it is the good instrument of people's studying the geography, though it is different that tradition is used for the terrestrial globe apparent size of geographical teaching, but mainly all be by base, support, spheroid three parts form, and sphere is a world map that indicates geographical longitude and latitude, this terrestrial globe has been brought into play positive effect in long-term teaching, but existing function of globe is single, be merely able to check more intuitively the geographic position, be merely able to provide the displaying effect of simple plane at geography class, can not give expression to intuitively the situation of earth rotation, also can't intuitively embody changing round the clock, can not satisfy teachers and students and use needs.

The utility model content

The technical problems to be solved in the utility model is for above deficiency, a kind of geographical teaching multifunctional globe is provided, overcome the defective that function of globe is single in the prior art, teaching efficiency is poor, after adopting terrestrial globe of the present utility model, have advantages of diverse in function, teaching efficiency visual pattern.

For solving above technical matters, the utility model is by the following technical solutions: a kind of geographical teaching multifunctional globe, comprise base, support and spheroid, spheroid is fixed by support, it is characterized in that: be provided with the clockwork box between described support and the base, be provided with clockwork in the clockwork box, clockwork is connected with the clockwork spring handle, the clockwork spring handle is given prominence to outside the box body of clockwork box, and the output shaft of clockwork is connected with spheroid;

Described support is closed hoop, is socketed with mobile light source on the support, and mobile light source can slide along the terrestrial globe warp direction.

After the utility model adopts above technical scheme, compared with prior art, have the following advantages: described terrestrial globe is provided with clockwork, the output shaft of clockwork is connected with spheroid, the clockwork spring handle of rotation clockwork, unclamp hand after upward expiring clockwork spring, slowly rotation of spheroid, classmates can see the rotation process of the earth intuitively; Be socketed with mobile light source on the support, mobile light source can slide along the terrestrial globe warp direction, demonstrates round the clock to change vividly, student's learning interest and understandability have been improved, it is concrete changing abstract, and more easily teaching condition is provided, and simple in structure, easy to use.

Below in conjunction with drawings and Examples the utility model is elaborated.

Description of drawings

Accompanying drawing 1 is the structural representation of terrestrial globe among the utility model embodiment;

Among the figure,

The 1-base, 2-clockwork box, 3-support, 4-spheroid, 5-mobile light source, 6-clockwork spring handle.

Embodiment

Embodiment, as shown in Figure 1, a kind of geographical teaching multifunctional globe, comprise base 1, support 3 and spheroid 4, spheroid 4 is fixing by support 3, be provided with clockwork box 2 between support 3 and the base 1, be provided with clockwork in the clockwork box 2, described clockwork is known technology general knowledge, indicates among the figure, the clockwork spring handle 6 of clockwork is given prominence to outside the box body of clockwork box 2, the output shaft of clockwork is connected with spheroid 4, and rotation clockwork spring handle 6 unclamps hand behind the upper full clockwork spring, slowly rotation of spheroid 4, the student can see the rotation process of the earth intuitively;

Support 3 is closed hoop, is socketed with mobile light source 5 on the support 3, and mobile light source 5 can slide along the terrestrial globe warp direction, and vivid demonstration changes round the clock.

The above is giving an example of the utility model preferred forms, and the part of wherein not addressing in detail is those of ordinary skills' common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation that carries out based on technology enlightenment of the present utility model is also within protection domain of the present utility model.
