Abstract

The utility model relates to a globe, the structure of which comprises a sphere, a bracket and a bracket shaft. The utility model is characterized in that the structure of the sphere is composed of a large and a small spherical caps, and a fixing disk which is positioned on the bottom face of the large spherical cap and is printed with the time zone and a transparent time sign disk group which can be rotated around the bracket shaft, wherein the fixing disk and the transparent time sign disk are respectively arranged between the two spherical caps; the integration can be assembled on the bracket shaft to form a complete outer sphere of the globe. When the small spherical cap of the utility model is taken away and the time sign disk is rotated, the time difference relations of time zones and the sunshiny conditions can be clearly seen on a plane. The outer shapes of the globe are not changed in the utility model, the utility model has the advantages of simple structure and convenient operation, and the utility model is suitable for practical use.

Description

Terrestrial globe

The utility model relates to a kind of terrestrial globe.

Selling in the city now and the terrestrial globe of people's use only is that the world map that will dwindle is printed on the ball, is an earth model that has dwindled.This kind terrestrial globe can only be seen some countries, the present position, area, though also can calculate the time zone thereon, but the people can't see 24 time zones simultaneously, the time difference in interval relation in the time of can not reflecting intuitively, reach phenomenon round the clock, this is in routine work, particularly in teaching process, can bring great inconvenience to people, the method of several this kind of solution problems is disclosed in the Chinese patent literature, wherein some is one or two circle of outer cover with terrestrial globe, in order to time and the sun direct projection situation that shows each time zone, but this kind method can not be seen 24 time zones simultaneously, can not reflect each time zone time difference and sun direct projection situation on a figure intuitively.

The purpose of this utility model is to provide a kind of can see 24 time zones simultaneously, and can reflect each intuitively the time interval the time difference and shine upon the terrestrial globe of situation.

The purpose of this utility model is achieved in that

A kind of terrestrial globe, comprise spheroid, support, support shaft in its structure, sphere structure is made up of two spherical crowns of size, and be provided with the shaft collar that is printed on the time zone that is positioned on the large ball prefix bottom surface between two spherical crowns, with the transparent time tag dish group that can rotate around support shaft, whole can being assembled in forms the outer spheroid of a complete terrestrial globe on the support shaft

The utility model is divided into 24 equal portions with shaft collar, and it is marked with time zone and corresponding with the longitude on the terrestrial globe.

The utility model is divided into 24 equal portions with the time tag dish, and it is marked with the time, and indicates terminator.

Be provided with isolating pad between the utility model shaft collar and the time tag dish.

The utility model time tag dish is fixed on the support shaft.

The utility model support shaft top is provided with the unlatching handle, and the unlatching blind nut is arranged on the handle.

Advantage of the present utility model is that it does not change the shape of original terrestrial globe, just portion adds the dish group of being made up of two dishes within it, open little spherical crown, by rolling disc group or large ball prefix, the time difference corresponding relation in interval and shine upon situation in the time of then can clearly reflecting each, make people can in one plane understand relation between time zone, the time difference and the sun direct projection intuitively, receive relevant knowledge quickly.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model A enlarged drawing.

Accompanying drawing 3 is the utility model B enlarged drawing.

Accompanying drawing 4 is the utility model shaft collar synoptic diagram.

Accompanying drawing 5 is the utility model time tag dish synoptic diagram.

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in drawings, the total structure of the utility model comprises spheroid 1, support 2, support shaft 3, and spheroid 1 is divided into two spherical crowns 4,5 of size.Wherein between two spherical crowns, large ball prefix 4 bottom surfaces are provided with a shaft collar 6 that is printed on the time zone.Shaft collar 6 is fixedly installed on the bottom surface of large ball prefix 4, and shaft collar 6 has been divided into 24 equal portions, and it is marked with the time zone, and its time zone is corresponding with the longitude on the terrestrial globe, also indicates the direction 9 of earth rotation on the shaft collar 6.Being provided with one on shaft collar 6 can be around the time tag dish 7 of support shaft 3 rotations, shaft collar 6 is isolated by isolating pad 8 with time tag dish 7, time tag dish 7 is divided into 24 equal portions, be carved with time and terminator 10 above, a check plate that freely picks and places 11 wherein can be set on the time tag dish 7, rotate separately in order to prevent bead hat 5.Two ends at time tag dish line in 7 morning and confused line intersection 10 can be provided with register pin 12, insert it in the pin-and-hole of bead hat 5, time tag dish 7 is made by transparency material, can be clear that time zone above the shaft collar 6 by it, just can therefrom see the time difference between the time zone and the situation of sun direct projection by rotating time tag dish 7 in this dish group, also time tag dish 7 can be fixed on the support shaft 3, it can not be rotated, press the earth rotation direction then and rotate large ball prefix 4, also can realize above-mentioned effect.Also be provided with unlatching backhand 13 at the top of support shaft and open blind nut 14, blind nut 14 is opened in turn, by opening handle 13, bead can be preced with 5 and take off, so that observation dish group.

Claims (6)

1, a kind of terrestrial globe, comprise spheroid, support, support shaft in its structure, it is characterized in that sphere structure by the size two spherical crowns form, and be provided with the shaft collar that is printed on the time zone that is positioned on the large ball prefix bottom surface between two spherical crowns, with the transparent time tag dish group that can rotate around support shaft, whole can being assembled in forms the outer spheroid of a complete terrestrial globe on the support shaft
