Abstract

The utility model relates to a clock capable of displaying universal times. The utility model is characterized in that a reversing gear is additionally arranged between a minute wheel and an hour wheel of an ordinary pointer clock. At the same time, the number of teeth of the minute wheel and the hour wheel are twice increased than the numbers of an ordinary clock. Thus, a minute hand clockwise run a round, an hour hand anticlockwise run a round. At the same time, the hour hand forms an hour hand disc according to the marks of time zones. Therefore, the universal clock can simultaneously display the local times of the same time in 24-hour zones. The operation is very convenient.

Description

Universal time-piece

The utility model relates to time set, particularly a kind of clock and watch that can show universal time.

The journey abroad, or with carry out communication contact abroad, the time difference is a very nerve-wracking problem.According to the natural law of earth rotation from West to East, the earth circled in per 24 hours, turned over 15 ° of longitudes in promptly one hour.Therefore stipulate in the world that every time zone of 15 ° of divisions, the whole world is divided into 24 time zones.Promptly be benchmark with the first meridian, time zone from 7.5 ° in west longitude divides into to 7.5 ° of east longitudes to the west of middle time zone, is divided into the Xi Yi district successively to western No.12 District; To the west of middle time zone, be divided into the Xi Yi district successively to western No.12 District.East No.12 District and western No.12 District are respectively striden 7.5 ° of longitudes, are combined into a time zone.Concerning any two time zones, differ several time zones therebetween, synchronization just differs several hrs.Also the principle regulation is the separatrix of " today " and " yesterday " on the earth with 180 ° of warps in the world, i.e. " international date line " abbreviation " day line ".The eastern No.12 District time was the non-irrigateiest from day line in new one day on the earth, and the western No.12 District time the latest.Therefore, in order to show the time of various places simultaneously,, need hang the polylith clock and watch simultaneously in public places such as hotel, airports.And to the clock and watch that the individual uses, then can only be to a country, will set or set back hour hands ahead by its time zone, place, very inconvenient.

The purpose of this utility model is exactly will provide a kind of can show the universal time-piece of the local time of 24 time zone synchronizations in the world simultaneously.

For finishing the universal time-piece that the invention task designs, by casing and drive unit wherein, wheel and point gear are formed, its point gear comprises hour wheel, minute wheel, minute wheel, the dial plate parts, hour hands, minute hand and second hand, minute wheel is a driving wheel, by the back gear sheet, striding the tooth axle is connected with hour wheel, between minute wheel and the hour wheel, set up a tumbler gear, the gear ratio of minute wheel and hour wheel is twice than the ordinary clock and watch expansion simultaneously, make the minute wheel clockwise direction change 24 circles, hour wheel is counterclockwise changeed 1 circle, and hour hands are not single needles, but coil by the hour hands garden of time zone 24 five equilibriums, dial plate is that counterclockwise 24 equi-index plates of counting are to show hourage.

The utility model universal time-piece structural design is ingenious, only needs to improve a little on the basis of existing machinery formula clock and watch or pointer quartz table, just can show the local time of 24 time zone synchronizations on clock and watch intuitively simultaneously, uses very convenient.

In order on the utility model universal time-piece, to show number of days simultaneously, the single direction ratchet that 31 ratchets are arranged in the rotating shaft of being arranged on can be arranged on the back side of dials, one fixing driving lever is arranged on the dial plate, hour hands garden dish whenever turns around, driving lever is just stirred ratchet once, makes it rotate a tooth position, simultaneously, on the hour hands garden dish calendar display aperture is arranged, uniform digital contraposition on calendar display aperture and the single direction ratchet wheel face.

Embodiment further describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model embodiment universal time-piece structural representation.

Fig. 2 is the utility model World clock matrix section transmission synoptic diagram.

As shown in Figure 1, number when uniform 1-24 numeral is with demonstration on the dial plate 3, on behalf of the numeral of a time zone, each time zone arrow indication, 24 arrows on the clock garden dish 2 respectively be the time number of there and then, it is one minute that second hand 1 takes a round, minutes 4 numerals of passing by are 2.5 minutes, and taking a round is one hour.The alternate that shows number of days in the calendar display aperture 5.When this hole forwarded on the dial plate 3 24 numeral places to, the single direction ratchet 7 that the driving lever 9 on the dial plate 3 is stirred in the rotating shaft 6 was rotated a tooth position.Unidirectional stop means 10 can not reverse single direction ratchet 7.

As shown in Figure 2, the drive unit 16 of mechanical clock or digital quartz clock and watch drives second hand 1 by second pinion 17 and walks about, and making minutes 4 to walk about by minute wheel 12, minute wheel 12 is through tumbler gear 15 and stride tooth axle 13 and back gear sheet 14 drives hour wheels 11, drives hour hands garden dish 2 again and walks about counterclockwise.Because minute wheel 12 has enlarged one times with the gear ratio of hour wheel 11 than ordinary clock and watch, so minute wheel 12 clockwise direction are changeed 24 circles, hour wheel 11 just counterclockwise turns around.

Claims

1, universal time-piece, form by casing and wherein drive unit, train and point gear, its point gear comprises hour wheel, minute wheel, minute wheel, dial plate parts, hour hands, minute hand and second hand, minute wheel is a driving wheel, by the back gear sheet, stride the tooth axle and be connected with hour wheel, it is characterized in that setting up between said minute wheel and the hour wheel tumbler gear, minute wheel is twice than the ordinary clock and watch expansion with the gear ratio of hour wheel simultaneously, make the minute wheel clockwise direction change 24 circles, hour wheel is counterclockwise changeed 1 circle; Said hour hands are the hour hands garden dish by time zone 24 five equilibriums; Said dial plate is 24 equi-index plates of counting counterclockwise, to show hourage.

2, universal time-piece according to claim 1,31 tooth single direction ratchet in the rotating shaft of being arranged on are arranged on the back side that it is characterized in that coiling in said hour hands garden, one fixing driving lever is arranged on the watch face, hour hands garden dish whenever turns around, driving lever contact single direction ratchet once, make it rotate a tooth position, on the dish of said hour hands garden the calendar display aperture is arranged, uniform digital contraposition on calendar display aperture and the single direction ratchet wheel face.
