The earth each regional day-night change of earth rotation generation；Pass through relative 5 turns of the solar term dial of rotational time dial 6
It is dynamic, the concomitant rotation of shadow shield 43 is driven, the corresponding solar term of intermediate point of the radiation scope of light-emitting device 431 is changed, can be with
The change of caused earth solar term when intuitively the demonstration earth revolves around the sun.So that instrument not only possesses on the displaying earth round the clock
Every country and the function of Area distribution position, but also can intuitively observe solar term change and the change round the clock in each area
Change so that instrument is used for functional diversities during teaching demonstration round the clock, more facilitates teachers' instruction, also allow for children's understanding.
Wherein, in order that spheroid 4 can preferably be rotated around the straight line of the first connecting tube 31, the formation of the second connecting tube 32,
So as to realize the rotation of the earth；And shadow shield 43 can preferably be rotated around connecting portion, so as to be shadow shield 43 and time scale
The synchronous axial system of disk 6 provides possible, in the instrument round the clock that the present embodiment is provided, as Figure 1-4, and spheroid 4 includes earth episphere 41
With the earth lower semisphere 42 being connected with earth episphere 41, the arctic point of spheroid 4 offers first through hole respectively with Geophysical South Pole
With the second through hole, the first connecting tube 31 and the second connecting tube 32, the connection of the first connecting tube 31, second are provided with arc support 3
Pipe 32 is connected with arc support 3, and the first connecting tube 31 is located in first through hole, and connecting portion includes the second connecting tube 32 and connected
Spindle 432, the second connecting tube 32 and connecting shaft 432 are connected；The first axle sleeve 433 is provided with shadow shield 43, connecting shaft 432 passes through
Clutch shaft bearing is connected with the first axle sleeve 433；Second through hole is provided with the second axle sleeve 44, and the second connecting tube 32 passes through second bearing
441 are connected with the second axle sleeve 44, so that spheroid 4 can be rotated relative to the second connecting tube 32.
Spheroid 4 includes earth episphere 41 and earth lower semisphere 42, opens earth episphere 41, can be in order to shadow shield 43
Deng the installation and replacing of part.
First connecting tube 31 can be the parts such as shank, the body of rod, body, and its one end is fixedly connected with arc support 3, another
End is located in first through hole can be so that spheroid 4 be freely rotated around the first connecting tube 31；Second connecting tube 32 passes through the second axle
Hold the 441, second axle sleeve 44 to be connected with earth lower semisphere 42, connecting shaft 432 passes through the first axle sleeve 433, clutch shaft bearing and shadow shield
43 connections, are fixedly connected, the second connecting tube 32 is fixedly connected with arc support 3 between connecting shaft 432 and the second connecting tube 32, because
This, shadow shield 43 can be rotated relative to connecting shaft 432, the second connecting tube 32, and spheroid 4 can be rotated relative to the second connecting tube 32.Therefore,
Spheroid 4 can around the first connecting tube 31, the second connecting tube 32 formation straight line rotate, shadow shield 43 can opposing connections preferably turn
It is dynamic.
Specifically, in order that spheroid 4 can only from West to East revolve around the straight line of the first connecting tube 31, the formation of the second connecting tube 32
Turn, so that instrument does not influence to facilitate journey during teaching demonstration in the case of the correct sense of rotation of the simulation earth to greatest extent round the clock
Degree, the present embodiment is provided in instrument round the clock, as shown in Figure 2 and Figure 4, and second bearing 441 is unilateral bearing, relative to limit spheroid 4
The direction of rotation of second connecting tube 32 is from West to East.
Because the sense of rotation of the earth is that from West to East, therefore, during teachers' instruction should avoid turning spheroid 4 from east orientation west
It is dynamic, and then avoid student from producing the understanding of mistake to earth rotation direction, therefore, in the instrument round the clock that the present embodiment is provided, by the
Two bearings 441 elect unilateral bearing as, spheroid 4 is from West to East rotated relative to the second connecting tube 32, and can not invert, and then
Make the correct sense of rotation of the simulation earth to greatest extent of instrument round the clock.
When actual production is manufactured, in order that graduated time ring 6 can only from West to East rotate relative to solar term dial 5, so that
Make in the correct revolution direction of the simulation earth to greatest extent of instrument round the clock, the instrument round the clock that the present embodiment is provided, as shown in figure 1, section
Restriction rotation section is provided between gas dial 5 and graduated time ring 6, with limiting time dial 6 with respect to solar term dial 5
Direction of rotation is from West to East.
Rotated by rotational time dial 6 relative to solar term dial 5, drive the concomitant rotation of shadow shield 43, make luminous dress
The corresponding solar term of intermediate point for putting 431 radiation scopes change, and can intuitively demonstrate caused when the earth revolves around the sun
The change of earth solar term.
Because the earth revolves around the sun to rotate from West to East, therefore, during teachers' instruction graduated time ring 6 should be avoided relative
Solar term dial 5 is rotated from east orientation west, and then avoids student from producing wrong understanding, therefore, this implementation to revolution of the earth direction
In the instrument round the clock that example is provided, rotation section is limited by being set between solar term dial 5 and graduated time ring 6 so that graduated time ring 6
Can only from West to East it be rotated relative to solar term dial 5, so that the correct revolution direction of the simulation earth to greatest extent.
Preferably, in order that shadow shield 43 can with the preferably synchronous axial system of graduated time ring 6 so that instrument possesses round the clock
When intuitively the demonstration earth revolves around the sun in the function of the change of caused earth solar term, the instrument round the clock that the present embodiment is provided,
As shown in Figure 1-2, position when being located at 6 in graduated time ring 6 and when 18 is respectively arranged with the first magnet；Shadow shield 43 is circle
Two ends on disk, shadow shield 43 positioned at disc level orient diameter position are respectively arranged with the second magnet 434.
Due to shadow shield 43 can relative connecting shaft 432 rotate, and be provided with the first magnet on graduated time ring 6,
The second magnet 434 is provided with shadow shield 43, therefore, when graduated time ring 6 rotates with respect to solar term dial 5, by the
Magnetic force between one magnet and the second magnet 434, can drive the synchronous axial system of shadow shield 43, and make the level side of shadow shield 43
When corresponding to 6 on graduated time ring 6 all the time to diameter and when 18 on position, and shadow shield 43 correspondence graduated time ring 6 6-18
When side be provided with light-emitting device 431, therefore, no matter how graduated time ring 6 rotates, and the light of light-emitting device 431 is all the time
The area of covering spheroid 4 is daytime during side, i.e. 6-18 during the 6-18 of irradiation time dial 6, and spheroid is covered during 18-6
4 area is night.
Wherein, in order that light-emitting device 431 is preferably illuminated, so allow round the clock instrument preferably demonstrate earth each department
