The purpose of this utility model be research a kind of simple in structure, replace 24 clock and watch with, with low cost, clock and watch at one's leisure, represent the clock and watch of local time and other time zone times of the world simultaneously.

The utility model is a kind of clock and watch of representing 24 time zone times in the world simultaneously.According to the earth ceaselessly rotation eastwards from the west at a moment, the earth turned over 15 ° of longitudes in one hour, by stipulating that in the world every time zone of 15 ° of divisions, the whole world is divided into 24 time zones from circling (360 °) in per 24 hours.The utility model mainly connects main hour hands, dial, minute hand, second hand by casing for clock and watch, gearing, Chart of Time Zones of the World dish and constitutes.Gearing drives expression the azimuthal projection world synoptic diagram of overlooking the earth and the center scale (secondary hour hands) in other time zones, and the Chart of Time Zones of the World dish and the main hour hands of representational important city, time zone or key city locations mark; Expression has 24 time zones, 24 numerals (or mark) of express time on the dial; Dial maintains static, the Chart of Time Zones of the World dish adopts time identical with earth rotation and direction walking (rotation) with main hour hands, main hour hands are represented the local time, and the center scale in other time zones (secondary hour hands) is represented other time zone times, thereby represents the time in each time zone, the world simultaneously.

The utility model is compared with existing clock and watch, and the advantage that has is more complete, the more convenient practicality of function.Existing clock and watch can only be represented the local time, these clock and watch can be represented the time in local time and other time zones, the world simultaneously, and need not calculate the mistiming in other time zones, how much time of knowing these time zones at a glance is, be daytime or evening, made things convenient in the international contacts clocking requirement other time zone times of the world.Existing clock and watch are 12 hours systems, and these clock and watch are 24 hours, carry out 24 hours systems with train, aircraft, broadcasting, TV equal time and 24 hours are that one day the natural law is coupled, and have made things convenient for people to adopt the clocking requirement of 24 hours systems.

The drawing explanation of accompanying drawing

1---the Chart of Time Zones of the World dish

2---dial (maintaining static)

3---main hour hands (being connected as a single entity) with Chart of Time Zones of the World dish 1

4---minute hand (the same) with existing clock and watch

5---second hand (the same) with existing clock and watch

6---international date line on the Chart of Time Zones of the World dish

7---on the Chart of Time Zones of the World dish other the time district center scale (secondary hour hands)

8---24 time zone dividing lines on the Chart of Time Zones of the World dish

9---the numeral or the mark of express time on the dial

10---24 time zone dividing lines on the dial

Chart of Time Zones of the World dish 1 and main hour hands 3 are connected as a single entity, and this dish is gone up expression the azimuthal projection world synoptic diagram of overlooking the earth and the center scale (secondary hour hands) 7 in other time zones, and mark has the mark of representational important city, time zone or key city locations.Drive Chart of Time Zones of the World dish 1 and hour hands 3, minute hand 4, direction that second hand 5 is identical with earth rotation walk (rotation) by gearing, main 3 walking (rotation) weeks of hour hands are 24 hours, 4 walking (rotation) weeks of minute hand are one hour, and 5 walking (rotation) weeks of second hand are one minute.Dial 2 is a shaft collar, and this dish is gone up numeral or the mark 9 that expression has 24 time zone dividing lines 10 and 24 express times.

Main hour hands 3 referred to 15 o'clock Beijing time on the accompanying drawing, in the time of can finding out on the Chart of Time Zones of the World dish 1 each district center scale (secondary hour hands) refer to when Tokyo 16, during Sydney 17, during San Francisco 23, during New York 2, during Sao Paulo 4, during Paris 7, during Cairo 9, during Karachi 11, during Singapore 14 or the like.If 3 walkings (rotation) of main hour hands are to 20 o'clock Beijing time, then during Tokyo 21, during Sydney 22, during San Francisco 4, during New York 7, during Sao Paulo 9, during Paris 12, during Cairo 14, during Karachi 16, during Singapore 19 or the like.
