A watch with a lunar calendar indicating mechanism

Abstract

The invention discloses a watch with a lunar calendar indicating mechanism, comprising a movement, a dial and a lunar calendar indicating mechanism; a plurality of display windows are opened on the dial, the movement provides support for the lunar calendar indicating mechanism, and the lunar calendar indicating mechanism includes a plurality of command Wheels, command levers controlling each command wheel, and controlled components; the interaction between command wheels and command levers generates variable variables, and multiple variable variables interact on the controlled components and are displayed through windows. The beneficial effects are: since the leap month recognition is accomplished through the annual calendar cam and the monthly calendar cam, the single cam structure is simplified, the size of the parts is also reduced, and the processing difficulty is reduced; the structure of the lunar calendar leap month is calculated mechanically, and the leap month display of the lunar calendar watch It can be done automatically without manual adjustment; in addition, the cam can also toggle the moon phase display device, and the wheel dial can toggle the heavenly stem wheel and the earthly branch wheel, so the many functions included in the lunar calendar can be displayed through the corresponding window.

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.
