Abstract

A round-the-world watch comprises a watchcase, a watch dial and a transmission mechanism. The utility model is characterized in that the watch dial is driven to rotate by the transmission mechanism, the watch dial rotates for one circle in 24 hours, representative place names in all time zones of the world are marked in the circumferential direction of the watch dial according to the longitude positions of the earth, time scales from 1 to 24 are evenly marked in the circumferential direction of the watchcase, which is corresponding to the circumferential direction of the watch dial. The utility model has simple structure, and can reflect the time of all the time zones of the world visually and correctly, the rotating speed of the watch dial is the same as the rotation velocity of the earth, thereby the natural law of the diurnal variation of the earth can be visually represented, and the utility model is suitable for being used by people around the world.

Description

Global clock

Technical field

The utility model relates to clock and watch, relates in particular to a kind ofly can represent the Global clock of time all over the world.

Background technology

Traditional clock and watch can only be represented the time in a time zone.Along with the opening in the world, the contacts between the people of various countries are constantly strengthened, and people press for and a kind ofly can represent the Global clock of time zone time all over the world.Before the utility model proposes, though world clock also appearred, their structure more complicated, and the shown time is not directly perceived.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple in structurely, can intuitively show the Global clock of each time zone time of the world.

For achieving the above object, the utility model adopts following technical scheme: a kind of Global clock, comprise watchcase, dial plate and gear train, its special character is that dial plate is by the gear train driven in rotation, twenty four hours revolves and turns around, according to the longitude station mark of the earth representative place name in each time zone, the world is arranged at the circumferencial direction of dial plate, with the corresponding watchcase circumferencial direction of dial plate evenly mark 1 to 24 time scale is arranged.

In such scheme, described dial plate links to each other with gear train by the two-stage gear pair, and the reduction gear ratio of this two-stage gear train is that output speed is 1/2nd of the secondary reduction gear ratio of this position single gear of ordinary clock and watch than input speed.

In such scheme, minute hand and/or second hand are housed on the described dial plate, described minute hand shaft gear is meshed with the follower gear of first order gear pair, and described second hand axle is directly driven by the gear train of ordinary clock and watch.

Clocking method of the present utility model mainly is reflected on the dial plate, and original hour hands have become the some place names that mark on the dial plate, and walking about of former hour hands becomes the rotation of existing dial plate.Second hand of the present utility model, minute hand are the same with former ordinary clock and watch, be 60 systems, different is, and minute hand of the present utility model takes a round (1 hour), dial plate is walked little lattice, and (angle is 15 degree, be evenly lattice of the time scale of mark of watchcase circumferencial direction), angle 30 degree of walking little lattice than the hour hands of ordinary clock and watch in one hour are slow one times, but timing precision is the same with ordinary clock and watch.

The utility model is simple in structure, can reflect the time in each time zone, the world intuitively, exactly, and the speed that its dial plate rotates is identical with the speed of earth rotation, the natural law that the energy visual representation earth changes round the clock, and the people that are suitable for all over the world use.

Embodiment

See figures.1.and.2, the utility model is made up of watchcase 1, dial plate 14 and gear train 9, wherein, dial plate 14 passes through two-stage gear pair (gear 5,6,7,11) driven in rotation by gear train 9, twenty four hours revolves and turns around, be marked with the shape table place name in the world each time zone according to the longitude station of the earth every 15 scales at the circumferencial direction of dial plate 14, with dial plate 14 corresponding watchcase 1 circumferencial directions evenly mark 1 to 24 time scale is arranged, 15 degree of being separated by between adjacent two time scales.

At dial plate 14 surface printings the pattern of hour hands is arranged, this hour hands pattern can point to user's permanent residence, also can point to a certain specific area according to user's requirement, to be convenient for people to use.

Minute hand 13 and second hand 2 also are housed on dial plate 14, and the

second hand axle

12,8 of second hand 2 is directly driven by gear train 9.The minute hand shaft 3 of minute hand 13 is meshed with the follower gear 6 of first order gear pair by minute hand shaft gear 10.The reduction gear ratio of above-mentioned two-stage gear train is that output speed is 1/2nd of the secondary reduction gear ratio of this position single gear of ordinary clock and watch than input speed.

Gear train of the present utility model is identical with the ordinary clock and watch gear train.Piece number 16 is table lids, and piece number 15 is case side wall.

In sum, the utility model is not only novel, and practical, and the design of its innovation really can intuitively show each time zone time of the world, and it is simple in structure, and is easy to use, has substantial characteristics and progress, creative.

Claims

1, a kind of Global clock, comprise watchcase, dial plate and gear train, it is characterized in that dial plate is by the gear train driven in rotation, twenty four hours revolves and turns around, according to the longitude station mark of the earth representative place name in each time zone, the world is arranged at the circumferencial direction of dial plate, with the corresponding watchcase circumferencial direction of dial plate evenly mark 1 to 24 time scale is arranged.

2, according to the described Global clock of claim 1, it is characterized in that described dial plate links to each other with gear train by the two-stage gear pair, the reduction gear ratio of this two-stage gear train is that output speed is 1/2nd of the secondary reduction gear ratio of this position single gear of ordinary clock and watch than input speed.

3, according to the described Global clock of claim 1, it is characterized in that on dial plate, being equipped with minute hand and/or second hand, described minute hand shaft gear is meshed with the follower gear of first order gear pair, and described second hand axle is directly driven by the gear train of ordinary clock and watch.
