The world time zone disc is driven to rotate in the clockwise direction by the machine core through the drive of a drive mechanism, and the rotation period is 24 hours. The circumference is marked with every practical time zone mark and international date lines according to time difference relationships of practical time zones of every country or location in the world. The world time scale ring is inlaid on the dial disc of the outer circle of the world time zone disc, and the circumference thereof is marked with world time scale marks of 24-hour system.

Description

Universal time-piece

The utility model relates to a kind of clock and watch when indicating simultaneously countries in the world or area practical.

As everyone knows, also in rotation, the cycle of revolution was 1 year when the earth revolved around the sun, and the cycle of rotation promptly is one day.Like this, variation has throughout the year been arranged not only on the earth, and had round the clock alternately and the difference of time order and function.For the ease of worldwide timing, on the geography earth surface is divided into 24 time zones by longitude, the time difference in adjacent time zone is 1 hour, when what is called that Here it is is geographical.

In the social life of reality, countries in the world or area are not all to be as standard time of this country or this area during directly with geography, but delimit out separately practical time zone during based on geography and according to the actual conditions of various countries or each department, stipulate out the standard time separately.For example, although the domain of China is unified with the standard time of Beijing time as the whole nation across 4 geographical time zones, so the whole of China only has a practical time zone.Japan is the standard time with the Tokyo time, but it differed 1 hour with Beijing time, rather than 2 hours time differences of geography.The U.S. and Australian domain be also across a plurality of geographical time zones, and they are to be the standard time during with geography basically.India and Iran are the standard time with New Delhi, capital and Teheran time respectively, but the time difference in they and adjacent time zone be not 1 hour, but half an hour.This shows practical time zone and in people's social life, have more practical significance when practical than geographical time zone with when geographical.Particularly, in aviation, navigation, tourism, commerce and trade and other international association, not only to accurately grasp the local time, need to grasp simultaneously the in the world utility time of other country toward contact.Chronograph timepiece of the prior art (comprising wrist-watch, pocket-watch, desk clock and wall clock etc.) mostly is 12 hours systems greatly, not only can't distinguish daytime and night, and can only indicate the local time, can not indicate the correct time in other practical time zone simultaneously, therefore can not adapt to the needs of aviation, navigation, tourism, commerce and trade and other international association.

The purpose of this utility model promptly is to design a kind of universal time-piece can indicate countries in the world or area practical simultaneously the time.

To achieve these goals, the utility model utilization is installed in the interior dial plate of table cover, indicator, movement, world time zone coils and the universal time calibration loop consists of a clock universal time-piece.Indicator comprises minute hand and second hand, and it cooperates branch and second when being used to indicate practicality with the dial plate of 60 fens systems.World time zone's dish drives clockwise direction by movement by gear train and rotates, rotation period is 24 hours, its periphery indicates each practical time zone mark by the time difference relation in countries in the world or regional practical time zone, it is worked in coordination with being embedded in its peripheral 24 hours system universal time calibration loops showing to put, in the time of can indicating countries in the world or area practical simultaneously.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model universal time-piece.

Accompanying drawing 1 is the structural representation of the utility model universal time-piece;

Accompanying drawing 2 is world time zone's dish gear train structural representation.

With reference to the accompanying drawings 1,2, the utility model universal time-piece mainly is made of table cover and the movement, dial plate, indicator, world time zone's dish and the universal time calibration loop that are installed in the table cover.Dial plate 1 is circular, is fixed on the central authorities of table cover, and its periphery indicates the scale of 60 fens systems.Indicator comprises minute hand 2 and second hand 3, is installed in the center of dial plate 1 and can be driven by minute hand pipe and second hand pipe respectively by movement to rotate clockwise around the dial plate center, and rotation period was respectively 60 minutes and 60 seconds.World time zone dish 4 is disc, is made by transparent material, is installed in the top of dial plate 1 and concentric with dial plate 1.World time zone dish 4 can be driven clockwise by transmission mechanism by movement and rotate, and rotation period is 24 hours, also can be by table when stirring the school.The periphery of world time zone's dish 4 indicates each practical time zone mark 5 by the time difference relation in countries in the world or regional practical time zone, indicates international date line 6 from disc centre to New Zealand's time zone mark.Universal time calibration loop 7 is an annular, is embedded in that world time zone coils that the table of 4 peripheries puts and works in coordination with world time zone dish 4, and its periphery indicates 24 hours system universal time scales 8.

World time zone dish transmission mechanism can adopt multiple pattern, for example can consist of by main hour wheel, big idle wheel, little idle wheel with from hour wheel.Main hour wheel 9 can by movement by the time actuated syringes rotate clockwise, rotation period is 12 hours, big idle wheel 10 intermeshes with main hour wheel 9 and can be driven counterclockwise by main hour wheel 9 and rotates, rotation period is 12 hours.Little idle wheel 11 rotates with big idle wheel 10 coaxial counter clockwise directions, and rotation period is 12 hours.Coil 4 from hour wheel 12 with world time zone and be fixed into one, intermeshing from hour wheel 12 and little idle wheel 11 also can drive clockwise rotation by little idle wheel 11, and rotation period is 24 hours.

The utility model structure is ingenious, easy to use, as long as proofread and correct to local when practical stirring world time zone dish by table, in the time of can accurately indication countries in the world or area are practical simultaneously.
