Watch with lunar calendar indication mechanism

Abstract

The invention discloses a watch with a lunar calendar indication mechanism. The watch comprises a movement, a dial plate and the lunar calendar indication mechanism. The dial plate is provided with a plurality of display windows, the movement provides bearing power for the lunar calendar indication mechanism, the lunar calendar indication mechanism comprises a plurality of command wheels, a command rod for controlling each command wheel and a controlled part, the command wheels interact with the command rod and generate variables, and a plurality of the variables interact with the controlled part and are displayed through the windows. Beneficial effects of the watch are that because the leap month identification is completed by a year calendar cam and monthly calendar together, the structure of a single cam is simplified, the size of parts is reduced, and the processing difficulty degree is reduced; the structure is capable of calculating the lunar calendar leap month in a machinery manner, and the watch can automatically display the lunar calendar leap month without manual regulation; furthermore, the cams can dial a moon phase display device, an intermediate wheel dialing head dials a celestial stem wheel and a terrestrial branch wheel, thus a plurality of functions included in the lunar calendar can be displayed through corresponding windows.

Description

technical field [0001] The invention relates to a watch, in particular to a watch with a lunar calendar indicating mechanism. Background technique [0002] In the watchmaking industry, the Gregorian calendar is widely used, while the lunar calendar with Chinese characteristics is rarely involved. The main reason is that the lunar calendar is a calendar that takes into account the relationship between the sun, the moon and the earth. With its complex calculation method and irregular leap month setting, even the lunar leap month calculated by astronomy and calendar experts cannot guarantee that it can be accurately calculated for more than 200 years. Therefore, it is extremely difficult to present it mechanically in a timepiece with a very small space.

Problems solved by technology

Its complicated calculation method and irregular leap month setting, even the lunar leap month calculated by astronomy and calendar experts, cannot guarantee that it can be accurately calculated for more than 200 years

Therefore, if you want to present it mechanically in a watch with a very small space, it is extremely difficult

[0003] The clocks and watches related to the display of the lunar calendar that have appeared so far basically need to be manually adjusted during the leap month, and cannot automatically pass the calendar and display accurately.

[0004] In the published patent CN100593142C, a structure for automatically displaying the leap month was invented, but in the structure, the annual calendar cam relied on for the recognition of the leap month is too large, resulting in a lot of constraints on the structural arrangement and the size of the movement

Moreover, because the depth of the cam teeth is graded too much and the spacing is too close, it is also quite difficult to process.
