At present, used single clock can only show the local time of concrete country both at home and abroad, and the world clock that really can carry out global timing does not also have.

Though someone once designed a kind of clock and watch of world clock by name, its structure is to indicate the disk in longitude and national city in interior circle rotation, time scale is fixed at cylindrical, its design is " simulation " design, belongs to the some clocking method, and technical is enumerating of phenomenon and data, as the pattern of 12 division of day and night, 12 numbers, longitude etc., thereby have the following disadvantages: 1, there is difference in national time zone and theoretical time zone, and be promptly inconvenient, also inaccurate with the terrestrial longitude read time; Distinctive emblem when 2, not having, the relation of bad understanding district center line time and time zone service time, Qu Shinan reads; 3, do not have area code, the mistiming difficulty is read; 4, the time of seeing needs to find earlier country on Moving plate, and dish goes up Chinese character and rotate in time and have direction to change (oblique), looks and reads inconvenience; The clock and watch image is not good etc.

Summary of the invention: the utility model purpose is to solve clock and watch can show countries in the world, each time zone time simultaneously, reads conveniently, comes into plain view, and do not change problems such as clock and watch external form and meter reading custom.

Design philosophy: the utility model is the universe phenomenon that the regular motion of the earth is produced, and uses astronomical method, designs to show the various times, is used for the world clock of global timing.As everyone knows, the earth this in rotation, simultaneously around sun revolution, thus people can feel day, month, the variation of stars, this time dependent stars state is called division of day and night or tense.

Because one week of earth rotation is 24 hours, it all is to be a cycling element with 24 hours that the tense of earth surface any part changes, so, the international regulation whole world is divided into 24 time zones (and the division in time zone be not strict divide by terrestrial longitude), can think that each time zone diel all has 24 tenses to change.Therefore the design of world clock must with 24 hours be time-count cycle, consider to keep perfectly clock and watch image of tradition simultaneously as far as possible, and accomplish that as far as possible multinational timing comes into plain view.

The utility model world clock, comprise housing, dial plate, hour hands, minute hand, second hand reaches mainly by hour hand axle, gear C on the hour hand axle, minute hand shaft, gear A on the minute hand shaft, transaxle, the movement that gear B on the transaxle and B ' and second hand axle are formed, it is characterized in that former dial plate is set to the domain, be printed on district's ring and the every minute and second scale formed in 24 time zones on its card, each time zone angular indexing is 15 degree, the every minute and second scale will be distinguished ring and be divided into interior ring and outer shroud, interior ring is decorated with the time zone, the regional boundary line joins with district's center line and with hour indicator, and outer shroud has and the corresponding regional boundary of interior ring, area code and country and urban landmark; The transformation of the way of former hour hands is hour indicator, is printed on 24 markers on its card, the time be marked with word, mark coupling, its angular indexing is 15 degree, each markers represent one to distinguish hour hands.

Hour hand axle and minute hand shaft ratio of revolution changed 1: 24 into by original 1: 12 in the corresponding movement.Be that the cog number of teeth of A of minute hand shaft is 14 in the movement, the cog number of teeth of C of hour hand axle is 60, and the cog number of teeth of B and B of transaxle is respectively 56 and 10.

The utility model advantage and effect: 1, this world clock can show the time in each time zone, the world simultaneously, has really realized world's timing, is genuine world clock; 2, can direct-reading universal time (Greenwich Mean Time); But during the district in 24 time zones of 3 direct-reading, but at least 55 countries of direct-reading (mark) and 13 area (city) times; But the 4 direct-reading various countries mistimings; 5, can make common table and use, also can globally use and need not adjust; 6, the domain card can mark English-Chinese two kinds of literal, also can mark the literal of the local country in each time zone, and is widely applicable; 7, the domain design has the geographical configuration sense, and meter reading is convenient, can increase geographical general knowledge again; 8, have cancellation local " time system ", carry out the effect of 24 hours systems, be convenient to the propelling of global integration process.
