A large and small self-ringing control mechanism of a self-ringing mechanical watch

Abstract

The invention discloses a large and small self-ringing control mechanism of a self-ringing mechanical watch. The large and small self-ringing control mechanism comprises a large self-ringing control mechanism and a small self-ringing control mechanism. A time inquiring pawl control rod and a status control rod which are pressed together can be rotated around the axis center of a pressing nail. A time inquiring pawl control rod spring and a status switching rod are fixed on a clamping plate. A control cam and a control wheel are pressed together. Two operating surfaces on the outer edge of the control cam contact the status switching rod. A time inquiring pawl can be rotated around a time inquiring pawl shaft. A gear on the outer edge of a time inquiring wheel drives the time inquiring pawl to operate. A starting cam is rotated with a machine core minute wheel. The operating end of the starting cam contacts the second operating end of a push rod. Therefore, the push rod is pushed clockwise. The operating end of the push rod pushes the time inquiring pawl to be rotated counterclockwise. The large and small self-ringing control mechanism has beneficial effects that large self ringing and small self ringing are converted by controlling the time inquiring pawl, that the automatic time telling structure is capable of giving time according to a habitual sequence of hours, quarters, and minutes, and that an original self-ringing structure is simplified and a processing requirement is reduced.

Description

technical field [0001] The invention relates to a self-sounding mechanical watch; in particular, it relates to a large and small self-sounding control mechanism of the self-sounding mechanical watch. Background technique [0002] A self-sounding mechanical watch is a watch that can tell the time automatically. The automatic timekeeping function of the self-sounding mechanical watch is divided into a grande sonnerie and a petite sonnerie. The grande sonnerie tells the time on the hour, and the hour and quarter; the petite sonnerie tells the time on the hour, only a few quarters; the difference between the grande sonnerie and the petite sonnerie lies in whether the hour is What time is reported; the order of reporting the time of the self-sounding watch is to report the quarter first, then the minute, and finally the hour. The switching of the big and small sonnerie of the self-sounding mechanical watch is realized by whether the time-telling wheel is started. The big sonner...

Problems solved by technology

However, the self-sounding conversion of the self-sounding mechanical watch with this structure is realized by the sub-wheel control mechanism, which requires high manufacturing precision of the control structure and increases the difficulty of production and processing; The order of telling the time is different, which will also cause inconvenience to people's normal use
