A fixed timing disc of the periphery of the movable disc is respectively arrayed with the names of the major countries and the cities that are in the different time zones in the world according to the rule of the international time difference in the counterclockwise direction. The names of the major countries and cities are corresponded with the time pointings on the rim of the movable disc. The time of the movable disc is divided into the time of day and the time of the night. When the movable disc rotates along the shaft of the hour hand in the clockwise direction, each time pointing of different time segment respectively points to the countries and the cities in different time zones, which can achieve the purpose of knowing about the local time of different countries and visual distinguishing the day time and the night time.

Description

Day and night make the international clock table

The utility model relates to a kind of clock table, especially relate to a kind of by variant time zone country and the city be when maintaining static punctuate in time between the day and night system international clock table that then rotates of numeral flag along with hour hand axle.

At present, when known clock table is punctuate in time between numeral flag for maintaining static, hour hands then rotate with hour hand axle, daytime and night are all just the same, can not can only judge round the clock with available light and experience from the time at clock table differentiation daytime or night.Especially the local time of the many countries in the world is difficult to grasp especially, though many clock tables that hang as the hall, hotel are represented the local time of each main cities respectively, often can not grasp the locality, various countries intuitively from the clock table is to be in the daytime or the time at night.

Can not understand the country and the deficiency of city local time of a plurality of different time zones intuitively in order to solve existing clock table, the utility model provides a kind of international clock table of day and night making, this clock table can not only be grasped the country of each different time zone of the world and the local time in city on same clock table, and the local time that can distinguish each country and city very intuitively is to be in daytime or night.

The purpose of this utility model is achieved in that the number of teeth of the gear ratio of hour hands transmitting gear being made the hour hands transmitting gear of clock table in the movement housing in known existing 12 hours just in time doubles, the size of teeth and hour hands transfer motion speed changing gear coincide mutually and rotate, make hour hand axle whenever round the clock twenty four hours just in time rotate a circle, minute hand and other gearing are constant.By the time punctuate and time figure sign counterclockwise be arranged in the edge of a movable disc respectively by twenty four hours system, a disc centre hole is arranged in the centre of movable disc, with at 6 o'clock in morning of movable disc and at 6 o'clock in afternoon the place be divided into daytime and nights two part and put on sign and indicating night on daytime, the disc centre hole is inserted and secured on the hour hand axle.On the fixedly time dial of movable disc periphery, counterclockwise arranging the major country in variant time zone, the world and the name tag in city by international time difference rule respectively, fixedly time dial around arrange concrete every minute and second numeral flag more in the direction of the clock, divide the basis of time of second hand as identification directly perceived.When being because of known clock table punctuate in time between numeral flag be stationary arrangement, rotate with clockwise direction by hour hands, the utility model then by the time punctuate in time between numeral flag rotate, just in time opposite with it, so counterclockwise arrange by time difference rule in various countries and city, minute hand and second hand still rotate constant with clockwise direction.When the time figure sign of pressing arrangement counterclockwise on the movable disc rotates along with the hour hand axle clockwise direction, each the time punctuate just in time point to local time in various countries city respectively, reach the local time of grasping each different time zone country and discern the purpose of time round the clock.

The beneficial effects of the utility model are: can grasp this country the local time time, can also grasp the local time in other major country of the world and city, and can distinguish each foreign country locality intuitively and be daytime or hours of darkness, and easy to use, simple in structure.

Fig. 1 is the unitized construction synoptic diagram of hour hands transmitting gear of the present utility model and other gearing.

Fig. 2 is an embodiment synoptic diagram of the present utility model.

Among the figure during 1. hour hands transmitting gears, 2. hour hands transfer motion speed changing gears, 3. hour hand axles, 4. minute hand transmitting gears, 5. second hand transmitting gears, 6. minute hand shafts, 7. second hand axles, 8. movement housings, 9. movable disc 10. punctuate 11. time figure signs indicate for 12. daytimes and to indicate 14. disc centre holes 15. fixedly time dial 16. countries and city name tag 17. every minute and second numeral flags 18. minute hands 19. second hands 13. nights

In Fig. 1 Fig. 2, the gear number of teeth of known existing 12 hours systems of the gear ratio of the hour hands transmitting gear (1) in the movement housing (8) clock table just in time doubles, the size of teeth and hour hands transfer motion speed changing gear (2) coincide mutually and rotate, make hour hand axle (3) whenever round the clock twenty four hours just in time rotate a circle, the number of teeth of minute hand transmitting gear (4) and second hand transmitting gear (5) is identical constant with 12 hours system clock tables, make per 60 minutes of minute hand shaft (6) rotate a circle, second hand axle (7) rotates a circle per 60 seconds.Middle inner ring in clock body front has a movable disc (9), a disc centre hole (14) is arranged in the middle of the movable disc (9), disc centre hole (14) are inserted and secured on the hour hand axle (3), movable disc (9) by the time punctuate (10) and time figure sign (11) counterclockwise be arranged on the edge by twenty four hours system, at 6 o'clock in the morning and at 6 o'clock in afternoon the place be divided into daytime and nights two part, and indicate sign on daytime (12) respectively and indicate (13) night, daytime, sign (12) place pointed represented that respectively the locality is the time on daytime, and night, sign (13) place pointed represented that respectively the locality is the hours of darkness.On the fixedly time dial (15) of movable disc (9) periphery, the major country and the city name tag (16) of counterclockwise arranging each different time zone by international time difference rule is corresponding mutually with the time punctuate (14) of movable disc (9) respectively.As Tokyo Zao a hour, be arranged in the left side, Pekinese apart from Beijing time early one time in the position of punctuate (11) than Beijing time; Bangkok, THA late one hour than Beijing time, when then being arranged in the right side, Pekinese in the position of punctuate (11) apart from one of evening Beijing time, all arrange the major country of different time zone and the name tag in city (16) respectively by this rule, when movable disc (9) is rotated along with hour hand axle (3) clockwise direction, each the time punctuate (10) and different time figure signs (11) can point to each different country and city name tag (16) respectively, grasp the local time of various countries, for convenience minute hand (18) and second hand (19) come timing intuitively, indicate concrete every minute and second numeral flag (17) respectively in the fixing border, edge of time dial (15).Movable disc (9) whenever round the clock twenty four hours rotate a circle, minute hand (18) rotated a circle in per 60 minutes, second hand (19) rotates a circle per 60 seconds.
