Embodiment Construction

[0012] Since the time difference between each time zone is in hours, therefore, on the same clock face, the minute hand and second hand (if it exists) can be used in common for each time zone, and the time difference between each time zone is only reflected in the On the hour hand, and this time difference must be an integer multiple of hours. For the clock face, a week of 360 degrees is divided into 12 hours. Therefore, on the clock face, the two radii with an angle of 30 degrees just reflect the time difference of 1 hour, and the angle of 30 degrees A radius that is an integer multiple of , reflects the time difference in hours.

[0013] Utilize above-mentioned assumption, the scheme of the present invention is as follows, refer to figure 1 Shown:

[0014] A multi-time zone clock 10, the time scales 11 on the clock face of the multi-time zone clock are distributed on the circumference of the first distance from the center of the clock face. The time scale is designed to b...

Abstract

The invention discloses a multiple-time-zone clock. Time scale on the clock surface of the multiple-time-zone clock is distributed on a circle with a first distance away from the center of the clock surface, an hour hand of the multiple-time-zone clock is in the shape of a disc with a second radius, and the second radius is smaller than the first distance. The disc shaped hour hand is provided with at least two indicate zones, each indicate zone is provided with a cover plate which has an identical color with the disc shaped hour hand, and the indicate zones have different colors from that of the disc shaped hour hand, wherein an include angle between two radiuses of any two indicate zones is any multiple of 30 degrees. By utilizing the technical scheme of the invention, the multiple-time-zone clock can indicate the time of multiple time zones on the same clock surface clearly and effectively.

Description

technical field [0001] The invention relates to the field of clocks and watches, in particular to a clock capable of simultaneously displaying time in multiple time zones. Background technique [0002] Due to the existence of time differences, it is often necessary to use a clock that can display time in multiple time zones. At present, for a clock displayed in digital form or time software running on a computer, it is relatively easy to simultaneously display the time in multiple time zones. However, for traditional clocks and watches using pointers, it is difficult to display multiple time zones on the same clock. If too many pointers are used for display, it will make it difficult to check the time. Therefore, in occasions where time in multiple time zones needs to be displayed at the same time, such as in a hotel lobby, multiple clocks may be used at the same time to display time in different time zones. [0003] The use of multiple clocks consumes resources and takes ...
