Abstract

The utility model relates to a world time clock and watch, which adds a circle of 24 time points to the prior clock and assembles a rotating time zone dial on the outer dial surface. The speed ratio of the rotating time zone dial to the clock speed is 1:2. The rotating time zone dial is marked with the names of global twenty four time zone cities. While a circle of 24 time points is added to the surface and a rotating time zone dial is added to the outer case of prior watches; wherein, the time zone dial is marked with the names of global twenty four time zone cities. The utility model has the advantages of simple structure, convenient use, simultaneous indication of the times and time differences in the global twenty four time zone cities, multiple clocks indication in a clock, and no morning and afternoon error.

Description

Zebra time clock and watch

(1) technical field: the utility model relates to a kind of clock and watch, particularly can intuitively show clock and watch zebra time of main cities time all over the world.

(2) background technology: all kinds of clock and watch both domestic and external mainly are clocking capabilitys at present, can only show the local time, and can not show each main cities local time of global various countries, and this brings time difference obstacle to carrying out various interchanges in the whole world.

(3) summary of the invention: the utility model provides a kind of simple in structure for this reason, and is easy to use and can show the time and the time difference in city, 24 time zones, the world simultaneously, and clock and watch zebra time of the mistake in supreme, afternoon.

The utility model is a kind of World clock, include the clock clock face, clock movement and by hour hands, minute hand, the second hand of movement spindle drive, increase by 24 time points of a circle on the clock face, and on the clock face outside surface, install one additional and rotate time zone disc, this the time panel dish by one group of transmission gear by the movement spindle drive, the rotating ratio that rotates time zone disc and hour hands is 1: 2, this rotation time zone disc subscript is marked with the city title in 24 time zones, the world.A kind of zebra time wrist-watch it include the wrist-watch surface, timepiece movement and by hour hands, minute hand, the second hand of movement spindle drive, increase by 24 time points of a circle in its surface, and set up a rotating time zone disc on surperficial shell, its time zone disc subscript is marked with city, 24 time zones, world title.

The utility model is simple in structure, and is easy to use, and it can show the time and the time difference in 24 time zones city, the whole world simultaneously, and a clock shows a plurality of time clock features, and supreme, afternoon mistake.

(5) embodiment:

On the clock face with an ordinary clock, increase by 24 time points of a circle, in its machine mandrel 2, fix a gear 3 again, by its drive number of teeth be one times of clock gear doubly take turns 4, use two equal diameters again, the gear 5 that the number of teeth is identical, 6, its diameter sum equals hour hand axle gear 3 and doubly takes turns 4 diameter sums, gear 6 is fixed in doubly takes turns on 4, gear 5 is placed on the hour hand axle, and rotatable, be equipped with on the gear 5 and rotate time zone disc 7, constituted the gearing that rotates time zone disc 7 like this, the rotating ratio that rotates time zone disc 7 and clock is 1: 2, and this rotates the city title that marks 24 time zones in previous generation circle on time zone disc.

On the surface 8 with general wristwatch, increase by 24 time points of a circle, on 8 the shell of surface, set up the time zone disc 9 that an available hand rotates then, write a Chinese character in simplified form world's city, 24 time zones title on the mark with Chinese or English on its time zone disc, promptly can be made into one zebra time wrist-watch.

Read the clock and watch explanation: when rotating time zone disc around 24 time points rotations, if read the time in a certain city, just see which time point this city is parked on, be exactly this city now of living in some, and divide and be consistent with every minute and second on this clock second, so just can read the time in this city.

Claims

1. World clock, include the clock clock face, clock movement and by hour hands, minute hand, the second hand of movement spindle drive, it is characterized in that increasing on the clock face 24 time points of a circle, and install one additional at the clock face outside surface and rotate time zone disc, this time zone disc is by one group of transmission gear, by the movement spindle drive, the rotating ratio that rotates time zone disc and hour hands is 1: 2, and this rotation time zone disc subscript is marked with the city title in 24 time zones, the world.

One kind zebra time wrist-watch, include the wrist-watch surface, timepiece movement and by hour hands, minute hand, the second hand of movement spindle drive, it is characterized in that the surface upward increases by 24 time points of a circle, and set up a rotating time zone disc on surperficial shell, its time zone disc subscript is marked with city, 24 time zones, world title.
