Abstract

The utility model discloses a multifunctional globe for teaching, comprising a base (1), a bracket (2), a semicircle mounting bracket (3) and a globe (9). The utility model is characterized in that a plurality of time zones are marked on the globe (9); an equatorial plane (4) is welded on the semicircle mounting bracket (3); a movable zonetime disc (5) is limited on the inner side of the equatorial plane (4) through an adjustable clasp on the equatorial plane (4); at the intersecting line between the equatorial plane and the ecliptic plane, an ecliptic plane (6) is horizontally welded on both sides; and a twilight compass is sleeved on the globe (9). The utility model has an advantage that the globe can be used for demonstrating the issues about the earth movement.

Description

The multifunction teaching terrestrial globe

One, technical field:

The utility model relates to a kind of instrument of geographical teaching of primary and middle school, particularly relates to a kind of terrestrial globe.

Two, background technology:

Now general terrestrial globe is more succinct, and the design philosophy of embodiment mainly contains: base is parallel with ecliptic plan; The earth's axis and base (ecliptic plan) be 66 ° 34 ' angle; Equatorial plane and ecliptic plan be 23 ° 26 ' angle, but not obvious.General terrestrial globe is difficult to be illustrated in the phenomenon that occurs in the earth rotation process that day alternates with night, when being difficult to show the local time that produces by rotation and district, be difficult to show yellow red angle, be difficult to show the variation of the solar noon sun height that produces by revolution, the forming of variation, the variation in the four seasons, five bands of length round the clock.

Three, technical scheme:

So the purpose of this utility model presses for deficiency that exists at general terrestrial globe and geographical teaching work, and a kind of multifunction teaching terrestrial globe that can show that day alternates with night, carry out time conversion is provided.

The utility model adopts following technical scheme: a kind of multifunction teaching terrestrial globe, comprise base, support, semi arch fixed mount, terrestrial globe, it is characterized in that: the terrestrial globe subscript is marked with the time zone, on the semi arch fixed mount, be welded with an equatorial plane, the behaviour area hour indicator is limited in equatorial plane inboard by the movable button on the equatorial plane, ecliptic plane is the level of state and is welded on equatorial plane both sides at the red angle intersection of Huang place, and morning and evening, snare was on terrestrial globe.

The utility model is according to the actual needs in middle and primary schools' geography especially senior geography teaching process, the a series of problems relevant with earth movements are concentrated on a ball to be solved, can select some parts selectively according to the minor issue that will solve and operate, have advantage directly perceived, vivid, simple, convenient, fast, that save.

Four, description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a three-dimensional structure diagram of the present utility model.

Five, embodiment:

The utility model is described in further detail with embodiment with reference to the accompanying drawings below:

By Fig. 1,2 as can be known, the utility model comprises base 1, support 2, fixed mount 3, the earth's axis 8, terrestrial globe 9, and these are much the same with existing terrestrial globe; Be welded with an equatorial plane 4 on fixed mount 3, the equatorial plane 4 is the annulus that internal diameter is bigger than terrestrial globe radius, has four movable buttons to can be used for fixed area hour indicator 5 on the equatorial plane 4; Behaviour area hour indicator 5 is by being that internal diameter is identical with the internal diameter of the equatorial plane 4, external diameter is littler than the external diameter of the equatorial plane 4,12 o'clock places at district's hour indicator 5 are provided with a direct sunlight line place warp manual controlled handle, and behaviour area hour indicator 5 is limited in the inboard of the equatorial plane 4 by the movable button on the equatorial plane 4; Ecliptic plane 6 is made by two steel semicircular ring, and the size and the equatorial plane 4 are much the same, is passing through the terrestrial globe centre of sphere and is being parallel to the plane on chassis and the intersecting lens place of the equatorial plane 4 is the level of state and welds; By mark the time zone is arranged at terrestrial globe (9); Enclosing 7 morning and evening is circles of a big 1cm of its radius ratio terrestrial globe radius, puts into along the earth's axis 8 and is enclosed within certain position on the terrestrial globe 9 as required.

The utility model can carry out time conversion by behaviour area hour indicator 5, encloses 7 morning and evening and shows that day alternates with night.

The utility model can also be represented the sun with the ball that the terrestrial globe radius equates with a radius, entire body is painted redness, can hold or be placed on another multifunction teaching with the centre of sphere in the mode on plane, ecliptic plane place by the student and use in the terrestrial globe support system when the rotation of demonstrating the earth and revolution motion.

The utility model can also be represented the moon with the ball that the terrestrial globe radius equates with a radius, with a great circle by north and south two limits is the boundary line, half paints black, half is a white, when the demonstration phases of the moon, in multifunction teaching is used the terrestrial globe system, terrestrial globe 9 is taken out, change the moon and represent ball to get final product.

Claims

1. multifunction teaching terrestrial globe, comprise base (1), support (2), semi arch fixed mount (3), terrestrial globe (9), it is characterized in that: terrestrial globe (9) subscript is marked with the time zone, on semi arch fixed mount (3), be welded with an equatorial plane (4), behaviour area hour indicator (5) is limited in the inboard of the equatorial plane (4) by the movable button on the equatorial plane (4), ecliptic plane (6) is the level of state and is welded on the equatorial plane (4) both sides at the red angle intersection of Huang place, and circle in morning and evening (7) is enclosed within on the terrestrial globe on the terrestrial globe (9).

2. multifunction teaching terrestrial globe according to claim 1 is characterized in that: 12 o'clock places of described district hour indicator (5) are provided with a direct sunlight line place warp manual controlled handle.
