Abstract

The utility model relates to a universal clock which solves the problem of directly indicating times of 24 time zones in the world at the same time. The utility model is characterized in that a fixed dial disc is provided with the time numbers of the 24 time zones. A transmission device drives a world time zone chart disc with upward view global zenithal projection and is connected with a main hour hand and an auxiliary hour hand which use 24 hours to rotate one round. Therefore, the times of 24 time zones in the world can be directly indicated at the same time. The structure of the utility model is simple, convenient and practicable. The utility model can be widely used for obtaining the times of each time zone in the world at any time for government offices, companies and individuals.

Description

Universal clock

The utility model belongs to a kind of clock and watch of representing 24 time zone times in the world simultaneously.

The world in information age today, the progress of asking along with development of productivity and science skill, with frequent, people not only will know the local time more closely for the contact of human society and international contacts, and increasing people also usually needs to know the time in other time zones, the world.For example, people go abroad because of thing, and the Beijing time of taking off not only will be known in the New York of flying to by air, by plane from Beijing, also will understand the New York time that aircraft arrives.For another example, make a phone call from domestic external kith and kin or the contact business of giving, also usually run into matter of time, it is suitable to select when to make a phone call, and need know the other side's local time, and existing clock and watch can't be represented, very inconvenient.

The purpose of this utility model is a kind of simple in structure, convenient and practical, with low cost, 24 clock and watch of a kind table replacement of research, represents the clock and watch of local time and other time zone times of the world simultaneously.

Technical solution of the present utility model is: a kind of clock and watch of representing 24 time zone times in the world simultaneously.Used the characteristics of motion of the earth and the combination of time, and people are to the long-term custom of " clockwise ".Certainly circled (360 °) in per 24 hours according to 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.The utility model is by casing for clock and watch, gearing, the Chart of Time Zones of the World dish connects the major-minor hour hands, minute hand, second hand, dial is formed, its special character is that expression has the azimuthal projection Chart of Time Zones of the World of looking up the earth above the Chart of Time Zones of the World dish, this figure be with the Southern Hemisphere by azimuthal projection in the equatorial circle contour of figure, azimuthal projection is pressed outside the equatorial circle contour of figure in the Northern Hemisphere, the figure subscript is marked with the mark of 24 time zone dividing lines and each time zone representational important city title or position, time zone central meridian in the expression local time connects main hour hands, and the central meridian in other time zones is with one section scale vice hour hand; 24 numerals (or mark) that express time is arranged on the fixing dial, and the semicircle contour of expression time at night.Chart of Time Zones of the World dish and main hour hands walking (rotation) week are 24 hours, and 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 international contacts and the activities involving foreign nationals 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 and people's activities 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 of accompanying drawing is described as follows:

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

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 semicircle contour of expression time at night 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 looking up 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.Walked (rotation) by gearing drive Chart of Time Zones of the World dish 1 and hour hands 3, minute hand 4, second hand 5, main 3 walking (rotation) weeks of hour hands are 24 hours, and 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 the numeral or the mark of 24 express times arranged on this dish.

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 Los Angeles 23, during New York 2, during Sao Paulo 4, during Paris 7, during Cairo 9, during Karachi 12 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 Los Angeles 4, during New York 7, during Sao Paulo 9, during Paris 12, during Cairo 14, during Karachi 17 or the like.

Realize that best way of the present utility model is manufacturer production manufacturing or assembling.Shell of these clock and watch and minute hand 4, second hand 5 is the same with existing clock and watch, 24 numerals or mark that express time is arranged above the shaft collar 2 of these clock and watch, the Chart of Time Zones of the World dish 1 and the main hour hands 3 of these clock and watch are connected as a single entity, the Chart of Time Zones of the World dish 1 of these clock and watch and the link position of main hour hands 3 can be selected according to the local time that various countries use, if manufacture in China, use for China people, (120 ° of Beijing times of east longitude) are connected (as main hour hands 3 positions of accompanying drawing) to main hour hands with Chart of Time Zones of the World dish 1 in the Dong Ba district, if certain state manufactures, then the local time zone center scale that should use with certain state is that main hour hands position connects Chart of Time Zones of the World dish 1, and these improvement are easy to realize.The decapacitation of these clock and watch is satisfied outside the range of application of existing clock and watch, can also satisfy all establishment concerning foreign affairs, department, and all kinds of personnel concerning foreign affairs and the clocking requirement that other time zone times of the world need be provided are for activity of human beings provides timing appliance more easily.
