Abstract
The utility model discloses a calendar-changing mechanism of a watch. The calendar-changing mechanism includes a double-calendar hour wheel, a first date-changing wheel component, a daily calendar wheel, a month-changing wheel component, a monthly calendar wheel, and a second date-changing wheel component; the double-calendar hour wheel is engaged with the first date-changing wheel component; the first date-changing wheel component contacts with or is separated from the daily calendar wheel; the daily calendar wheel is engaged with the month-changing wheel component; a month-changing nail is inlaid on the month-changing wheel component; the month-changing nail can shift the monthly calendar wheel; and the monthly calendar wheel is engaged with the second date-changing wheel component. According to the calendar-changing mechanism of the watch of the utility model, calendar changing of long months and short months can be realized through a cam structure, so one times of manual adjustment of daily calendar is only needed in February in one year; and at the same time, the calendar-changing mechanism can assist in reducing the thickness of a watch movement and the difficulty in processing of parts.
Description
Technical field
The utility model relates to a kind of watch parts, particularly relate to a kind of 1 year only needs manually adjustment wrist-watch once change and go through mechanism.
Background technology
Pursue the development of newly peculiar psychology along with people, people have no longer satisfied the conventional indicating mode of wrist-watch, namely comprise the pointer of indicating hour, minute on Watch dail plate; The pattern of wrist-watch is also more and more novel.The patent No. is 99210721.0 to disclose the calendar mechanism of wristwatch that a kind of super large numeral date shows, wherein, and with position date rings and ten calendar-disc replace single date rings structure in the generic calendar wrist-watch one by one.Numeral on 10 calendar-disc and a numeral of a position date rings are combined into two figure places and indicate the date.This structure can strengthen the size of date numeral and also in calendar window the clear and distinctive date numeral that demonstrates, the wrist-watch wearer is easy to identify the date numeral.Its shortcoming is that wrist-watch thickness increases, and parts increase, and difficulty of processing is large.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of mechanical efficiency high, steadily, the changing of wrist-watch date of changing fast go through mechanism.
The technical scheme that the utility model adopts is: mechanism is gone through in changing of a kind of wrist-watch, comprises, day-date hour wheel, the first date finger driving wheel parts, date wheel, changes a moon wheel component, monthly calendar wheel, the second date finger driving wheel parts; Described day-date hour wheel and the engagement of the first date finger driving wheel parts; Described the first date finger driving wheel parts contact with date wheel or break away from, described date wheel with change the engagement of moon wheel component, described change to be inlaid with on moon wheel component change a month nail, the described month nail that changes is stirred the monthly calendar wheel, described monthly calendar wheel and the second date finger driving wheel parts engagement.
Described the first date finger driving wheel parts comprise that riveted is integrated changes day shifting block and the first date finger driving wheel, describedly changes that a day shifting block is stirred or away from date wheel; Described the second date finger driving wheel parts comprise the second date finger driving wheel that riveted is integrated and change a day cam, change a day cam and stir or break away from date wheel.
Described date wheel is 31 with the number of teeth of changing moon wheel component; Described monthly calendar wheel and the second date finger driving wheel are evenly distributed with 12 long teeth; Described periphery of changing day cam is evenly divided 12 deciles, comprises 7 hypodontias, 5 full-depth tooths.
The beneficial effects of the utility model are: the normal jumping that realizes the large solar month of 30 days of wrist-watch by cam structure is gone through, and therefore, wrist-watch only need to manually be adjusted in February a calendar in 1 year; Simultaneously, this mechanism has reduced the thickness of timepiece movement, and the difficulty of processing of parts.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
To shown in Figure 5, mechanism is gone through in changing of the utility model wrist-watch as Fig. 1, comprises, day-date hour wheel 10, the first date finger driving wheel parts 20, date wheel 30, changes moon wheel component 40, monthly calendar wheel the 50 and second date finger driving wheel parts 60; Described the first date finger driving wheel parts 20 comprise that riveted is integrated changes day shifting block 22 and the first date finger driving wheel 21, described day-date hour wheel 10 and the first date finger driving wheel 21 engagements, describedly change that day shifting block 22 is stirred or move day shifting block 22 and stir date wheel 30 and rotate a tooth away from date wheel 30, the first date finger driving wheels 21 band that rotates a circle; Described date wheel 30 meshes with changing moon wheel component 40, and described date wheel 30 is 31 with the number of teeth of changing moon wheel component 40; Described change to be inlaid with on moon wheel component 40 change month nail, the described month nail that changes is stirred monthly calendar wheel 50, described the second date finger driving wheel parts 60 comprise the second date finger driving wheel 61 that riveted is integrated and change day cam 62, described monthly calendar wheel the 50 and second date finger driving wheel 61 is evenly distributed with 12 long teeth, the 50 and second date finger driving wheel 61 engagements of monthly calendar wheel; Described periphery of changing day cam 62 is evenly divided 12 deciles, comprises 7 hypodontias, 5 full-depth tooths, and take one of them full-depth tooth as Qi Shichi, first and third, five, seven, eight, ten, 12 tooth is hypodontia, the described day cam 62 that changes is stirred or breaks away from date wheel 30.
The below describes the course of work of the indicating mechanism of the utility model wrist-watch:
A: February shifting block, b: April shifting block, c: June shifting block, d: September shifting block, e: November shifting block.
When monthly calendar is one, three, five, seven, eight, ten, during Dec, when date wheel rotates a week, change a moon wheel component and rotate a circle, change and change moon nail on moon wheel component and stir the monthly calendar wheel and rotate a tooth, change day cam and do not mesh with date wheel this moment on the second date finger driving wheel parts, and a tooth dallies.At this moment, completing smoothly date wheel changed from 31 days and goes through No. 1.When monthly calendar is four, six, nine, ten for the moment, when date wheel circles, changes a moon wheel component and rotate a circle, change and change moon nail on moon wheel component and stir the monthly calendar wheel and rotate a tooth, change day cam and date wheel engagement this moment on the second date finger driving wheel parts, stir tooth of date wheel rotation.Be equivalent to date wheel and turned two teeth, namely change by 30 days and go through 1 when the solar month of 30 days, passed through the tooth that two date wheels are stirred in two actions, also can complete smoothly the solar month of 30 days and change and go through.
When monthly calendar was February, this action and solar month of 30 days changed to go through and are designed to unanimously, and therefore, annual had 28 or changed in 29th and need to pass through calendar speed dial button adjustment calendar when going through 1 to February.
