Description

The multifunctional space time world clock

The utility model belongs to clock field, particularly a kind of multifunctional space time world clock.

Occur many clocks clock-type at present in the world, Chinese patent application numbers 88106907.8 discloses a kind of big world clock.Its outermost layer has a fixed address dish to indicate each time zone and main cities, in the dish of address a display panel is arranged, and there is a variable color colour display screen express time in each time zone, is used for the time and date that the centralized displaying world distinguishes for a long time, and the diameter of great bell is more than 0.8m.The function ratio of this clock is more single, and intuitive is relatively poor.

The purpose of this utility model provides that a kind of a day index dial, a hour scale division dish, rotating disc, Northern Hemisphere map etc. are formed by having, and can represent the function space-time world clock of time, year, month, day all over the world with timing in 24 hours.

Another purpose of the present utility model provides a kind of gear train with suitable ratio of gear, can realize the world clock to the transmission of day, the moon, hour hands.

According to multifunctional space time world clock of the present utility model, formed by the gear train of dial plate, pointer and pointer.Dial plate has two fixedly calibration circles, and EXT scale circle is a day scale, and 365 equally distributed scales represents 1 year 365 days, and interior calibration circle is hour, scale division is justified, and 24 dots are represented 24 hours, and scale is represented minute.Pointer has minute hand, day pin and month pin.The color of dial plate is deepened from top to bottom gradually, and hour hands and Northern Hemisphere map printing are on a rotating disc, and the external diameter of this rotating disc is about 5/8ths to 1/2nd of EXT scale circle less than interior calibration circle.The quantity of hour hands can be drawn on demand, for example, can respectively draw a hour hands arrow in each main cities of northern ball or position, capital, various countries.Rotating disc can be made with transparent plastic or organic glass.The rotation of rotating disc is signifying the rotation of the earth.

According to the utility model, the day clock front end is established a little ball, the expression 1 year that rotates a circle, and the symbol earth rotates a circle around the sun.

According to the utility model, the round dot place on the top of interior calibration circle establishes a light source, is signifying the solar light irradiation earth, shines daytime and night that bright-dark degree on the map represents each position of the earth.

According to this usefulness novel multifunctional space-time world clock, on the basis of ordinary clock and watch kinematic train, increase day pin kinematic train, the revolution of hour hands moves a week, i.e. and in a moving week of rotating disc revolution, a day pin rotates lattice, and its ratio of gear is

Consider movement volume and gear size, can adopt the secondary transmission gear shift, ratio of gear is resolved into i day=5 * 71.

According to the utility model, on hour hand axle, tell a cover month pin kinematic train, circle than one slow approximately 40 minutes of week of earth rotation around the earth according to the moon, promptly hour hands (rotating disc) revolution is 360 °, and month pin rotates 350 °, and it passes than being The moon, the pin front end was established a crescent moon, and the symbol moon rotates around the earth.

According to multifunctional space time world clock of the present utility model.Can express the moment of various places, the Northern Hemisphere (or the Southern Hemisphere) simultaneously, express formed daytime of earth rotation and night, can also express the moon, can not only give the correct time, and can also demonstrate a clear and definite concept of space around the situation that the earth rotates.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the synoptic diagram of dial of the present utility model.

As shown in Figure 1, dial of the present utility model is made up of two dial scale circles, four indicators, a rotating disc.Two calibration circles are formed by EXT scale circle (2) and interior calibration circle (3).EXT scale circle (2) is divided into 365 scales to represent 1 year 365 days.Interior calibration circle (3) is gone up uniform 24 round dots, represents 24 hours; Be carved with 60 equally distributed scales simultaneously, the representative minute.Round dot place, interior calibration circle (3) top establishes a light source (9), the expression sunshine.

As shown in Figure 1, the utility model is provided with three and rotates indicator, and a day pin (8) directs at EXT scale circle (2), and its front end is provided with a little ball, and the expression earth rotates lattice and represents one day.Calibration circle in minute hand (7) points to rotates lattice and represents 1 minute, calibration circle inboard in a month pin (6) points to, and its front end is provided with a crescent moon, represents the moon to change around the earth, rotates 350 ° in one day.The color of dial plate is deepened from the top down gradually, the variation at expression daytime and night.

As shown in Figure 1, the interior transparent material of rolling disc (4) (as transparent PVC plastics or organic glass) is made, and its diameter is about ～5/8 of EXT scale circle.Card is provided with earth hemisphere map (5), map as the Northern Hemisphere, also can adopt the map in the Southern Hemisphere on demand, the moment that a radius " pointer " (1) " pointer " indication is drawn in the capital, various countries from map is this national local time, and this pointer is hour hands.Drawn concentric circles is a terrestrial latitude on the map, and each bar radial line is represented longitude.

Movement according to multifunctional space time world clock of the present utility model can adopt quartz clock movement, also can adopt mechanical gear clockwork spring movement.Increase the kinematic train of a cover day pin on the basis of existing movement, make hour hands (being rotating disc) revolution move a week (representing one week of earth rotation), a day pin rotates lattice, and its ratio of gear is

For realizing this ratio of gear, can adopt secondary transmission deceleration system, ratio of gear is decomposed into i _Day=5 * 71.Tell simultaneously an a cover month pin kinematic train again on hour hand axle, rotate than earth rotation slow approximately 40 a minutes week according to the moon around the earth, just rotating disc (hour hands) revolution is moving 360 °, and month pin rotates 350 °, thus the moon pin the ratio of gear of kinematic train
