Abstract

The utility model discloses an international clock which can simultaneously display the zone times at the same time in the 24 longitude zones on the whole earth. A timing core system can adopt a mechanical timing system or a quartz electronic timing system. The international clock adopts a 24 hours timing system; an hour hand rotates one circle every 24 hours; the international clock makes the international timing standardized. The international clock is suitable for airports, stations, quays, families, individuals, and geographical teaching.

Description

International clock

The utility model relates to a kind of clock that clocks, and particularly a kind ofly can demonstrate each longitude of full earth international clock of zone time.

Existing time clock (as mechanical clock, stem-winder, quartz analog clock, quartz watch etc.), can only demonstrate the longitude zone time that the user aims at, can not demonstrate each longitude of full earth zone time simultaneously, adopt 12 hours duration rate systems, be not easy to the world standardization of clocking, for international airline, navigation, tourism and post and telecommunications, use very inconvenient.

The purpose of this utility model is to provide a kind of international clock, can demonstrate the time all over the world on same clock face, adopts 24 hours duration rate systems, is convenient to the world standardization of clocking.Be convenient to international airline, navigation, tourist industry and post and telecommunications and use, also provide a kind of suitable teaching aid simultaneously for the geographical knowledge teaching.

The utility model is achieved in that the structural principle of international clock and common clock roughly the same, promptly by the movement system that clocks, manually allot device, and face, pointer (when comprising, minute, second pin), formations such as calendar system, casing.Adopt 24 hours duration rate systems.Minute, second scale on the face is 1～60 five equilibrium, and small time taking is 1～24 five equilibrium.Have the calendar hole on the face, can show two day date simultaneously.24(promptly 0) with 12 line be ' midnight's line ', ' midnight's line ' east side is to being new one day between the day line, ' midnight's line ' west side is to being old one day between the day line.The hour hands of pointer be the time zone through scale, 24 needle points that evenly distribute on it, the respective regions time in each 15 ° of zone of needle point indication terrestrial longitude.The zone is printed on hour display disc in turn by middle time zone (London), Dong Yi district (Berlin) to eastern Shi Yi district (Noumea), thing No.12 District (Wellington), western Shi Yi district (Ah criticizing Asia) to Xi Yi district (Reykjavik).Can forward print, also can reversely print.The movement system that clocks can adopt mechanical timing system, also can adopt quartz electronic timing system.Pointer sense of rotation by the movement system control of clocking can adopt up time to turn to, and to adapt to people's use habit, also can adopt the inverse time to turn to, and is promptly consistent with the earth rotation direction, makes things convenient for geographical teaching to use.Rotation speed by the minute, second pin of the movement system control of clocking is identical with ordinary clock, the time zone through the hour hands of the speed ratio ordinary clock of scale slowly half, turned around in promptly 24 hours.For quartz electronic movement, only need with the hour hands oscillation frequency slack-off half get final product, for the machinery movement that clocks, only need increase the ratio of gear of hour wheel to be twice and get final product.

The utility model has compared to existing technology can demonstrate the advantage of time all over the world on same clock face, on the structure with ordinary clock roughly the same.Adopt 24 hours duration rate systems, be convenient to the world standardization of clocking.Being convenient to international airline, navigation, tourist industry and post and telecommunications and clocking, be suitable for airport, harbour, station, post and telecommunications, family and individual and use, also is one of teaching aid of geographical knowledge teaching.

The utility model further describes below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the clock face figure of international clock.Be made of through scale 1 and face 2 time zone, the time zone is even 24 needle points that distribute on scale 1, the respective regions time in each 15 ° of zone of needle point indication terrestrial longitude.By middle time zone (0 ° of longitude, London), Dong Yi district (15 ° of east longitudes, Berlin) to eastern Shi Yi district (165 ° of east longitudes, Noumea), (thing is through 180 ° for the thing No.12 District, Wellington), western Shi Yi district (165 ° in west longitude, Ah criticizing Asia) (15 ° of Reykjaviks of west longitude) are printed on the time zone in turn on scale 1 to the Xi Yi district.Can forward print, also can reversely print.The line that longitude is 0 °～180 ° is a day line.Fig. 1 prints by reverse (promptly identical with the earth rotation direction), is convenient to reason and computing method thereof that explanation produces " time difference ", " diurnal inequality ", and the teaching aid that can be used as geographical teaching uses.1～60 every minute and second scale of uniform printing on the face 2,1～24 small time taking.At 60(24) the word location place has the calendar hole, can show two days number of days.According to territory of use's difference, can be with the pointer in a certain time zone with heterochromatic notes with distinguishing mark (as Dong Ba district, Beijing), both convenient the use strengthens aesthetic feeling again.

Embodiment one, by quartz electronic timing system, manually allot device, minute hand, second hand, time zone and constitute through scale 1, face 2, calendar system, casing etc.Inverse time turns to, and clock face is pressed Fig. 1 and printed, with the hour hands oscillation frequency slack-off half, turned around through scale 1 in the time zone in per 24 hours.

Embodiment two, by mechanical timing system, manually allot device, minute hand, second hand, time zone and constitute through scale 1, face 2, calendar system, casing etc.Turn to clockwise, (promptly oppositely printing with Fig. 1) forward printed through scale 1 and zone and numeral on the face 2 in the time zone.The ratio of gear of hour wheel increased be twice, turned around through scale 1 in the time zone in per 24 hours.

Claims (4)

1, international clock by the movement system that clocks, manually allot formations such as device, face, pointer (when comprising, minute, second pin), calendar system, casing, is characterized in that:

(1) adopts 24 hours duration rate systems;

(2) the minute, second scale on the face is 1～60 five equilibrium, and small time taking is 1～24 five equilibrium;

(3) hour hands of pointer be the time zone through scale, 24 needle points that evenly distribute on it, the respective regions time in each 15 ° of zone of needle point indication terrestrial longitude.

2, the movement system that clocks of international clock according to claim 1 is characterized in that adopting mechanical timing system, also can adopt quartz electronic timing system.

3, the movement system that clocks according to claim 1 and 2 is characterized in that can adopting up time to turn to by the pointer sense of rotation under its control, also can adopt the inverse time to turn to.

4, pointer according to claim 1 is characterized in that by the rotation speed of the minute, second pin under the movement system control of clocking identically with ordinary clock, and the time zone rotates to be 24 hours and turns around through scale.
