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 CN 1987961A, a structure for automatically displaying the leap month was invented, but in the structure, the annual calendar command 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.

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0031] The lunar leap month execution mechanism of the clock of the present invention is particularly suitable for displaying the lunar calendar mechanism, especially the display of the lunar leap month, including multiple command wheels, command rods and controlled components for controlling each command wheel; multiple command wheels and corresponding The command rods cooperate with each other to produce multiple variable variables, and multiple variable variables interact on the controlled component, that is, the result is the product of multiple variable variables.

[0032] Now take two command wheels and command rod as an example for illustration, such as Figure 1a with Figure 1b As shown, the lunar leap month execution mechanism of the clock of the present invention includes a lunar month calendar command wheel system, a lunar year calendar comma...

Abstract

The invention discloses a lunar calendar leap month actuator of a timepiece, which comprises a plurality of command wheels, a command lever for controlling each command wheel, and a controlled component; Act on the controlled component. The beneficial effects are: since the leap month recognition is completed through the year command wheel and the month command wheel, the single cam structure is simplified, the size of the parts is also reduced, and the processing difficulty is reduced; The display of the leap month can be done automatically, and no manual adjustment is required; in addition, the recognition mechanism for the leap month of the lunar calendar occupies a small space and is convenient for arrangement.

Description

Technical field [0001] The present invention relates to a mechanical mechanism that displays discrete variables, which can display at least one irregular value among N regular continuous values ​​in a general cycle or N regular continuous values ​​in a special cycle. Background technique [0002] In the watchmaking industry, the Gregorian calendar is widely used, while the lunar calendar with Chinese characteristics is rarely discussed. 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 complicated calculation method and irregular leap month setting, even the lunar leap month calculated by the astronomical calendar cannot be guaranteed to be accurately calculated for more than 200 years. Therefore, if you want to display it in a clock with a very small space by mechanical means, it is extremely difficult. [0003] The clocks and watches related to the display of the lunar calendar that...
