world clocks

technical field

The utility model belongs to the field of watches and clocks, and relates to a clock and watch which can simultaneously indicate the time in all parts of the world.

Background technique

The earth is round, and since there are 24 hours in a day, we divide the earth into 24 time zones. Countries and regions around the world adopt convenient timing standards according to their own time zones, so the general time of countries and regions in different time zones in the world is different. Ordinary clocks and watches can only indicate the time in one region. With the increase of exchanges between people from various countries in the world, people need to know the time in different parts of the world more and more. Therefore, a set of clocks and watches are used in hotels, airports and other foreign-related places to display the time of the world. The standard time of the time zone or major cities, each clock is adjusted to the standard time of the indicated time zone or city; or use an analog world map, with a digital display or pointer type near the name of the city to display the time A clock showing the standard time for the city. Obviously, this system of displaying the time in the world time zone by combining multiple clocks is very stupid. Chinese patent ZL 99244492.6 provides a way to use a combined dial to display the time around the world, but this way can not directly see the time around the world, but also needs to know the time difference between other regions and the set standard time zone to calculate, which is more troublesome . At present, some wristwatches also provide a method capable of simultaneously displaying the time in different regions, but limited to the volume and aesthetic requirements of the wristwatch, and the requirement of accurately displaying hours, minutes and seconds, this method is complicated and expensive.

Contents of the invention

In order to overcome the defects of the above-mentioned clocks and watches and give full play to their advantages, the utility model provides a world clock and watch which adopts a standard electronic clock movement and can visually display the time of all parts of the world at the same time.

In order to achieve the above object, the utility model has taken the following technical solutions:

A world clock, including a concentric time dial and a time zone dial, and a 24-hour watch movement, the time dial is set inside the time zone dial; the center of the time dial is connected to the output shaft of the 24-hour watch movement, and at the time 24 time grids are evenly marked around the periphery of the disk, and the numbers 0-23 are marked clockwise next to the dividing line of the time grid, and each time grid is evenly divided into 4-6 small grids; the time zone disk and The shell of the 24-hour watch movement is fixed, and 24 time zone grids are evenly marked along the periphery of the time zone dial adjacent to the time dial, and 24 time zone grids are marked clockwise from time zone 0 to west zone 1 in the time zone grid The name of the world time zone, and the middle mark of each time zone grid points to the arrow of the time dial; the 24-hour watch movement adopts a standard 12-hour electronic watch movement, and the connection gear ratio of the hour hand output shaft of the watch movement is 1:2 The reduction gear set, the output shaft of the reduction gear set is used as the output shaft of the 24-hour watch movement.

There are more than two region names marked on the time zone disk, and the position of each region name mark corresponds to the time zone where the region is located. When the region uses the time zone plus 1/2 of the time zone where it is located, a special arrow is marked to connect the region Name to the junction of the current time zone and the next time zone and pointing to the time disk. The representative region names are directly marked on the time zone disk, which provides convenience for use in most cases.

If only paying attention to the representative area, the mark of the world time zone name can be omitted in the time zone plate, so that the dial is concise. Further, the marks of the 24 time zone divisions can be omitted to make the dial more concise.

A circle is marked in the middle area of the time disk, and the circle is divided into two halves, one half is filled with white, the other half is filled with black, the half filled with white corresponds to the numbers 6-18 in the time grid, and the half filled with black One half corresponds to the numbers 18-6 in the time grid. This gives an approximate indication of which areas are in daylight and which are at night.

The time zone disc adopts a dot-matrix display screen, which can be connected with a controller containing required region name information. This makes it possible to mark any region name on the time zone disc.

The use of the utility model is very simple. Observe the position of the time plate pointed to by the arrow in the middle of each time zone grid in the time zone plate, and the standard time of the time zone can be read according to the number and the small grid marked at the position, so that each The standard time of the time zone can be read at a glance, so that if you know the time zone of the region, you can know the standard time of the region. The watch movement in the utility model adopts a commonly used cheap 12-hour electronic watch movement, as long as a gear is connected to the hour hand output shaft of the electronic watch movement, and the gear is meshed with another gear with twice the number of teeth, it can be formed. An output shaft that rotates once in 24 hours can form the core part of the utility model world clock with this output shaft, so the utility model is simple and cheap. The utility model simply and clearly expresses the time of all parts of the world with one clock, changes the previous 12-hour clock mode, and realizes the wish that one watch can replace multiple watches; the scope of adaptation is relatively wide, and it is suitable for use in hotels and restaurants. It is suitable for traveling across time zones and connecting people in different time zones.

Detailed ways

Below in conjunction with accompanying drawing 1-3 the utility model is described further.

The utility model world clock and watch mainly is made up of time plate 1, time zone plate 2, 24 hours watch core. The time disk and the time zone disk are concentric disks; the time disk is set in the time zone disk, and the time zone disk surface is larger than the time disk surface (as shown in Figure 1); the time disk is connected to the output shaft of the 24-hour watch movement, and the time zone disk is connected to the 24-hour clock. The case of the watch movement is fixed.

24 time grids are evenly divided in a circle around the time disk, and numbers 0-23 are marked on the interval line of each time grid in a clockwise direction; 6 small grids are evenly divided in each time grid, and each small grid Indicates 10 minutes; and marks a half-white, half-black circle in the middle of the time disk, representing day and night, the white part of the circle corresponds to the number of time grid 6-18, and the black part of the circle corresponds to time grid 18-6 numbers.

In the time zone disk, 24 time zone grids 3 are evenly marked along the periphery of the time zone disk and the time disk, and 24 world time zone names are marked clockwise from time zone 0 to west zone 1 in the time zone grid, and each The middle of each time zone grid marks an arrow pointing to the time disk. On the periphery of the time zone disk, the representative region names in the world can be marked, such as the names of major cities, and the region name is connected with the time zone mark of the region; when the region uses the time zone plus 1/2 of the time zone, it is marked with a special arrow connection The area name is connected to the connection between the current time zone and the next time zone and points to the time disk (as shown in Figure 2). When highlighting the name of the region, the world time zone name mark can be omitted, and even the time zone grid mark can be omitted (as shown in Figure 3). In most cases, people only care about the time in individual regions, not the time around the world, so it can be more concise and clear . In order to mark any region name in the time zone disk, the time zone disk can adopt a dot-matrix display, including an interface with the controller, such as a USB port. The controller can be developed in addition, such as being composed of a single-chip microcomputer and a driving circuit, and corresponding programs are written to make the display screen display the required region name on the position of the time zone according to people's needs.

The 24-hour watch movement adopts the standard 12-hour electronic watch movement. The hour hand output shaft of the watch movement is connected to a small gear, and a large gear is set in the center of the back of the time dial. The two gears mesh with a gear ratio of 1:2. In this way, the large gear drives the time dial to make one revolution in 24 hours.
