Abstract

A world clock is characterized in that a clock dial is graduated for 24 hours, a clock hand shaft rotates for one circle for 24 hours, the clock hand is a disc, a map of the southern hemisphere of the earth is drawn on the disc and divided into 24 time zones according to longitude, and international date change lines and city names of various major cities such as Beijing, Tokyo, London and the like in each time zone are marked to respectively represent time of each time zone. The minute hand and the second hand are not changed. The outer circle of the 24-hour scale of the clock dial is still divided into 60 scales for indicating the minute-second value by a minute hand and a second hand. Two date windows are arranged above the clock dial 0 at the same time and respectively display different dates in areas on two sides of the international date change line. The utility model discloses can show all parts of the world time simultaneously with a clock, make things convenient for people's life greatly.

Description

A kind of world clock

The utility model belongs to the improvement of Chronograph timepiece.

Before the utility model was made, clock was generally and turned around in 12 hours or 24 hours, but they all can only indicate a certain zone time in the world, just all need can not use a clock jointly with the clock indication various places time separately all over the world.Need know the occasion of time all over the world simultaneously, as International airport, harbour, TV station etc., the clock more than just need using several simultaneously, extremely inconvenient.

Task of the present utility model is for overcoming a kind of improved clock that the above-mentioned deficiency of existing in prior technology provides.

The utility model is to improve realization on the basis of existing technology, it comprises clock shell, clock dial, hour hands, minute hand, second hand, and clock dial is 24 small time taking systems, it is characterized in that hour hands are a disk, uniform 24 scales, and indicate each big city title such as Beijing, Tokyo, London by its time zone, place.

Fig. 1 is the utility model front view

Fig. 2 divides local enlarged drawing for clock portion among Fig. 1

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing:

According to Fig. 1, shown in Figure 2: 1 is clock dial among the figure, clock dial is 24 small time taking systems, uniform 24 scales, and 4 is minute hand, 5 is second hand, 3 is hour hands, and these hour hands are a disk, are divided into 24 time zones by longitude, corresponding with 24 small time taking systems of clock dial 1, and indicate each big city title of the world by its time zone, place, as Beijing, Tokyo, London etc., represent each location time with it.The hour hands disk revolved and turns around in 24 hours, and is synchronous from turning around from West to East with the earth.The hour hands disk is corresponding with clock dial like this, can demonstrate the time point in each time zone, the world simultaneously, as: 0 point is pointed in Beijing, and morning has been pointed to a bit in Tokyo, and London still is points in afternoons 16 yesterday.Minute hand, the second hand of clock and watch are constant., be used for minute hand, second hand and indicate the every minute and second value respectively still by 60 lattice calibration in clock dial 24 small time taking outer rings.

Two date windows 2 can be established in 0 o'clock of clock dial 1 top, can be painted with earth the Southern Hemisphere map and international date line on the hour hands disk 3, show on the hour hands disk international date line both sides same date not all over the world respectively with two date windows.International date line is crossed 0 point, the regional new daystart of modified line back, and the Qi Qu city enlarges gradually; The area of date line front, scope is dwindled gradually, up to finishing near 0 again.0 of clock dial is arranged at the top, and is identical with the map up north and down south, represent earth sun night simultaneously dorsad; Bottom 12 points are represented noon of the forward sun.

The utility model can also be designed to watch style or desk clock formula.

The utility model image, demonstrate the space-time concept(ion) of the earth intuitively, can point out the time all over the world simultaneously, adapted to modern civilization people life requirement efficiently.

Claims (3)

1, a kind ofly can show the world clock of time all over the world simultaneously, comprise clock shell, clock dial (1), hour hands (3), minute hand (4), second hand (5), clock dial (1) is 24 small time taking systems, it is characterized in that hour hands (3) are a disk, uniform 24 scales, and indicate each big city title such as Beijing, Tokyo, London by its time zone, place.

2, world clock according to claim 1 is characterized in that 0 o'clock top of said clock dial (1) is provided with two date windows (2), and the hour hands disk is painted with earth the Southern Hemisphere map and international date line on (3).
