Abstract

The utility model discloses a globe. Two semispheres clamp a wheel-shaped time vernier, which is labelled with digit graduation of 0, 1, 2, 3,.. 21, 22, 23 to indicate hour, minute, and second in sequence. The sphere is provided with a calendar display hole and a calendar contact exchange device. The inner of the sphere is arranged inside a time-piece movement and a transmission mechanism, and the sphere and the time vernier respectively rotate by a chucking device on a bracket. The utility model can not only intuitively display the relation of temporal and spatial variation of the earth and the sun, but also can be used as a world clock.

Description

Globe

The utility model relates to the instruments used for education field.

At present, the function of globe that uses in the teaching is single, and when especially utilizing it to lecture the global time difference course, the student is difficult for intuitivism apprehension.

The purpose of this utility model provides can the visual representation global time difference, can be used as the terrestrial globe that universal clock uses again.

The technical solution of the utility model is: by spheroid, support, the time vernier of the colyliform of spheroid sandwich that two hemisphere of the common terrestrial globe that base is formed are formed, the outer round surface of colyliform time vernier from left to right order mark has 0,1,2,3......21,22,23 digital calibration lines, digital calibration 5 to 7,7 to 17,17 to 19, be marked with unlike signal respectively between 19 to 5 four piece of digital, on spheroid, have the calendar display aperture, east longitude 180 ° (international date line) is provided with calendar with time vernier intersection and touches changing device on the spheroid, a main shaft passes spheroid, the time vernier, movement is connected with support, a watch and clock movement is installed in the spheroid, the movement hour hand axle connects with the time vernier by gear train, in mid-stent a gripping mechanism is installed, is stirred this device and can unclamp or tighten time vernier or spheroid respectively.The chucking time during vernier spheroid rotate from left to right, chucking spheroid then time vernier rotates from right to left.

Owing to adopted such scheme, the utility model can not only show the global time difference of the change in time and space relation of the earth and the sun intuitively, can use as World clock again, simple in structure, easy to use.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model user mode figure;

Fig. 2 is the utility model structural drawing;

Fig. 3 is the utility model time vernier figure;

Fig. 4 is the utility model time vernier sectional view;

Among the figure in 1,2,3: 1. spheroid, 2. the calendar display aperture, 3. calendar touches changing device, 4. time vernier, 5. support, 6. base, 7. main shaft, 8. movement, 9. hour hand axle, 10. gear pair, 11. dops;

As shown in Figure 1, 2, 3: the spheroid (1) of the common terrestrial globe of forming by spheroid (1), support (5), base (6), be split up into two hemisphere from equatorial line, the time vernier (4) of a colyliform of sandwich, colyliform time vernier (4) outer round surface from left to right order mark has: 0,1,2,3 ... 21,22,23 digital calibration line as the time, the minute, second sign, digital calibration 7 to 17 scale section coated white are represented daytime, 17 to 19,5 to 7 are coated with grey colour specification dusk and early morning, and 19 to 5 coating blacks are represented night.Have calendar display aperture (2) in the last position, the Pacific Ocean of spheroid (1), the last east longitude of spheroid (1) 180 ° (international date line) is provided with calendar with time vernier (4) intersection and touches changing device (3).A main shaft (7) passes spheroid (1), time vernier (4), movement (8), is connected with support (5), a watch and clock movement (8) is installed in first spheroid (1), and movement hour hand axle (9) is connected drive time vernier (4) rotation of turning left from the right side by a pair of gear pair (10) with time vernier (4).At support (5) middle part a Y type dop (11) is installed, dop (11) can unclamp or tighten time vernier (4) and spheroid (1) respectively, and chucking time vernier (4) then spheroid rotates from left to right.

Searching present Beijing as figure is Wednesday Dec 16, and 19: 15 are in time vernier black region is night.No matter be that time vernier (4) rotates from right to left or spheroid (1) rotates from left to right.Spheroid (1) is gone up calendar that east longitude 180 ° (international date line) locates and is touched changing device (3) and contact change calendar display aperture (2) time with time vernier (4) scale 0.

Claims (2)

1, a kind of terrestrial globe, by spheroid, support, base is formed, the time vernier that it is characterized in that the colyliform of spheroid sandwich formed by two hemisphere, the outer round surface of colyliform time vernier from left to right order mark has: 0,1,2,3,21,22, when 23 digital calibration line is represented, divide, second, digital calibration 5 to 7,7 to 17,17 to 19, be marked with unlike signal respectively between 19 to 5 four piece of digital, on spheroid, have the calendar display aperture, east longitude 180 ° (international date line) is provided with calendar with time vernier intersection and touches changing device on the spheroid, a main shaft passes spheroid, the time vernier, movement is connected with support, a watch and clock movement is installed in spheroid, and the movement hour hand axle is connected drive time vernier by gear train and rotates from right to left with the time vernier, in mid-stent a gripping mechanism is installed.

2, according to the said terrestrial globe of claim 1, the gripping mechanism that it is characterized in that the Y type can unclamp or tighten time vernier and spheroid respectively, and chucking time vernier then spheroid rotates from left to right.
