Perpetual calendar mechanism of mechanical watch

Abstract

The invention discloses a perpetual calendar mechanism of a mechanical watch, which comprises a command wheel component, a week calendar wheel component, a moon phase intermediate wheel component, a moon phase wheel component and a quick lifting lever, a double hour wheel, a 24 hour wheel component, an actuating lever component, a date changing lifting lever component, a calendar wheel component,a command lever component, a month changing ejector rob component, a month changing lifting lever component and a week changing lifting lever component, wherein the double hour wheel is meshed with the 24 hour wheel component which is contacted with the actuating lever component or separated with the actuating lever component; position pins on the actuating lever component are respectively embedded in grooves of the date changing lifting lever component and the week changing lifting lever component; the bulge of an command ejector rob is contacted with the calendar wheel component, and the other end of the command ejector rob is contacted with or separated with the command wheel component; and the month changing ejector rob component is contacted with the month lifting lever component. The perpetual calendar mechanism has the beneficial effects that the complete set of structure is controlled to run by a single lever and can be used for avoiding pushing the command lever component every day, is small in load and less in abrasion, the condition that a gear is driven to reverse and jump cannot occur when an elastic lifting block replaces; and the normal operation of the mechanism cannot be affected by a reversed lifting needle.

Description

Technical field [0001] The present invention involves a mechanical watch with a perpetual calendar institution, especially the entire perpetual calendar institution controlled by a single leverage. Background technique [0002] The perpetual calendar control agencies of existing mechanical watches are generally controlled by the calendar and weekly calendars. There are buttons for the calendar, weekly calendars, and month calendars. When the watch is adjusted, the calendar, week calendar, and month calendar are controlled by their respective buttons.For example, the open number applied for by the Swiss company is the open technical solution of CH20060000233. Among them, the dialing calendar, weekly calendar, and monthly calendar are all completed by multifunctional leverage. Therefore, the accuracy of the structure of the structure is highIn addition, the output wheel of the movement movement must promote the multi -functional leverage with large loads every day, increasing the w...

Problems solved by technology

For example, the publication number CH20060000233 applied by the Swiss company discloses the technical scheme, in which the dial calendar, weekly calendar and monthly calendar are all completed by multifunctional levers, so the structure requires high precision of the parts, so the processing of the parts is difficult. Moreover, the output wheel of the movement of the movement pushes the multifunctional lever with a large load every day, which increases the wear of the multifunctional lever, resulting in an increase in the production cost of the parts and a decrease in the service life.
