Problems solved by technology

Among them, the invention of a world clock with the announcement number CN 2927130Y discloses a method for quickly identifying the time in different time zones by using the cities marked by time zones on the hour dial and the time correspondence on the fixed dial, but it is still not very convenient and fast. Knowing whether it is day or night in different cities in each time zone is still not very convenient to use

Embodiment Construction

[0009] The present invention will be described in further detail below according to the accompanying drawings.

[0010] as attached figure 1 The shown world clock includes a fixed dial 1 and a world time dial 2, wherein the fixed dial 1 and the world time dial 2 are coaxially installed together and can rotate relatively, and the fixed dial 1 includes twelve Two equally divided rings, each equal division represents an hour, and the time represented by the two rings adds up to twenty-four hours; the world time disk includes two concentric twelve-equal divisions The rings represent the time zones of the Eastern Hemisphere and the time zones of the Western Hemisphere, and each division represents a time zone.

[0011] Wherein, the two rings of the fixed dial can be a female ring 8 and a male ring 9 connected end to end, the time point 4 of the female ring 8 is from 18 o'clock to 6 o'clock, and the time point of the male ring 9 is 4 from 6:00 to 18:00, where 0:00, 12:00 and 24:00...

Abstract

The invention provides a world clock, aiming to the problems that the time of cities in the world at different time zones can not be rapidly and accurately read and the time in day or at night can not be informed by the existing world clock. The world clock is composed of a fixed dial plate and a universal time plate, wherein the fixed dial plate and the universal time plate are arranged on the same axis and can be assembled together in an opposite rotation manner; the fixed dial plate comprises two rings which are divided into twelve parts equally along the circumferential direction, and areconcentric and connected with the fixed dial plate in an end-to-end manner, each part represents one hour and total time represented by the two rings is 24 hours; and the universal time plate comprises two rings which are divided into twelve parts equally, are concentric with the universal time plate and respectively represent time zones in the eastern hemisphere and time zones in the western hemisphere, each part represents one time zone, and a city name representing a corresponding time zone is labelled on a corresponding zone section. The world clock provided by the invention has simple structure, low manufacturing cost, simple and easily understood use method, and convenience and practicability.

Description

technical field [0001] The invention belongs to a clock panel, in particular to a world clock. Background technique [0002] At present, most chronograph watches display twelve hours on a fixed dial, and the indicated time on the clock will be adjusted accordingly according to the different time zones during travel. With the increasing frequency of global business exchanges and the continuous development of tourism in various countries, business travel and tourist travel across different time zones around the world have become a very important part of people's work and life. The demand for accurate local time has also increased, so different forms of world clocks have emerged. Among them, the invention of a world clock with the announcement number CN 2927130Y discloses a method for quickly identifying the time in different time zones by using the cities marked by time zones on the hour dial and the time correspondence on the fixed dial, but it is still not very convenient a...
