Abstract
A clock for world time relates to a clock able to indicate all time zones of the world simultaneously, composed of a clock sleeve, a clock dial in the clock sleeve, clock hands, a movement, a world time zone ring, a world time indicating ring and a transmission mechanism. The world time indicating ring counter-clockwise rotates through the movement being driven by the transmission mechanism, with the period of 24 hours. Everywhere in the world, it only needs to aim the practical time zone mark of the world time zone ring at the corresponding world time of the world time indicating ring to indicate the time of all time zones at any moment. With skillful structure and convenient timing, the utility model can indicate local time and indicate world time from time to time, and it can be made into the forms of desk clock, hanging clock or floor clock, etc.
Description
The utility model relates to a kind of clock and watch that are used for indicating simultaneously each time zone time of the world.
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 geographical time zones by longitude since cycle of earth rotation be 24 hours, so the time difference in adjacent geographical time zone is 1 hour.
In the social life of reality, countries in the world and area be not all be during with geography as standard time of this country or this area, but make separately standard time during based on geography and according to the actual conditions in various countries and area, or during the title practicality.For example, though the domain of China across 4 geographical time zones, the whole nation unified with Beijing time as the standard time, therefore have only a practical time zone.Japan is the standard time with the Tokyo time, but it differed 1 hour with Beijing time, rather than two hours time differences of geography.The U.S. and Australian domain be also across a plurality of geographical time zones, but be 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 geographical time zone be not 1 hour, but half an hour or 30 minutes.Obviously, practical time zone and in people's social life, have prior practical significance when practical than geographical time zone with when geographical.Particularly, in aviation, navigation, tourism and other international association, not only to accurately grasp the local time, need to grasp simultaneously the utility time of other countries and regions in the world toward contact.Various Chronograph timepiece of the prior art mostly is 12 hours standards greatly, not only can't distinguish daytime and night, and can only indicate the local time, can not indicate the correct time in other time zone simultaneously, therefore can not adapt to the needs of aviation, navigation, tourism and other international association.
The purpose of this utility model promptly is to design a kind of not only can indicate the locality time but also the universal time-piece can indicate other area, the world practical simultaneously the time.
To achieve these goals, the mechanism of the utility model base area revolutions, the universal time indicating ring of one annular being installed in the periphery of existing 12 hours standard timepiece dials and being driven with 24 hours by gear train by movement is counterclockwise to rotate around dial plate in the cycle, and universal time indicating ring circumference is divided into 24 equal portions and indicates the 1-24 arabic numeral that are used to indicate universal time successively.Meanwhile, the table in universal time indicating ring periphery puts world time zone's ring of inlaying an annular and can manually rotate around the universal time indicating ring, and the time difference relation that world time zone's ring is gone up by each practical time zone indicates each practical time zone mark and represents the city title.The dial plate of 12 hours standards and hour hands, minute hand, second hand still are used to indicate the local time.If world time zone's ring is gone up corresponding universal time on the local time zone markers align universal time indicating ring, can utilize universal time indicating ring and world time zone ring to indicate other time zone time of the world 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 2,3 is respectively the front elevation and the vertical view of gear train.
With reference to the accompanying drawings 1,2,3, the utility model universal time-piece mainly is made up of table cover and the dial plate, indicator, movement, world time zone's ring, universal time indicating ring and the gear train thereof 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 12 hours standard scales that are used to indicate the local time.Indicator comprises hour hands 3, minute hand 4 and second hand 5, and needle tubing 6 when passing through respectively, minute hand pipe and second hand pipe are installed in the center of dial plate 1 and can drive clockwise direction by movement and rotate, and rotation period was respectively 12 hours, 60 minutes and 60 seconds.Universal time indicating ring 7 is an annular, be installed in the periphery of dial plate 1, its circumference is divided into 24 equal portions and indicates the 1-24 arabic numeral that are used to represent universal time successively, its bottom has with the intermeshing gear ring 8 of gear train and can be driven counterclockwise by gear train by movement rotates, and rotation period is 24 hours.World time zone's ring 9 is an annular, the table that is embedded in universal time indicating ring 7 peripheries overlaps on 2 and with table cover 2 works in coordination, world time zone's ring 9 is worked in coordination with universal time indicating ring 7 and can manually be rotated along universal time indicating ring 7, and the time difference relation that world time zone's ring is gone up by each practical time zone indicates each practical time zone mark and represents the city title.
The pattern of universal time indicating ring gear train can be varied, and when being external toothing as the gear ring 8 of universal time indicating ring bottom, gear train can be made up of hour wheel 10, first idle wheel 11 and second idle wheel 12.Also needle tubing 6 clockwise direction rotation at any time on the needle tubing 6 when hour wheel 10 is fixed on, first idle wheel 11 and second idle wheel 12 are intermeshed and are meshed with hour wheel 10 and gear ring 8 respectively.When the needle tubing clockwise direction is rotated when movement drives, also drive the universal time indicating ring and counterclockwise rotate by hour wheel, first idle wheel and second idle wheel.Suitably select the ratio of gear of hour wheel, first idle wheel and second idle wheel, the rotation period that can make the universal time indicating ring is 24 hours.
In the utility model, the effect of dial plate, indicator is identical with common 12 hours standard clock and watch, still be used to indicate the local time, calibration method during with the school mechanism also identical with common 12 hours standard clock and watch.As long as any in the world area by manual world time zone ring, makes corresponding universal time on the time zone markers align universal time indicating ring in this time zone, can indicate the time in other time zone by world time zone's ring and universal time indicating ring at any time.
The utility model is simple in structure, ingenious, and is easy to use, both can be used for indicating the local time, also can indicate other time zone time simultaneously, and can make patterns such as desk clock, wall clock or case clock as required.
