Description
Technical field
The utility model relates to a kind of wrist-watch parts, particularly relates to a kind of monthly calendar mechanism of wrist-watch.
Background technology
Along with the development of technology, the function of wrist-watch becomes increasingly abundant, and monthly calendar shows has become a kind of very common watch function.The existing monthly calendar structure of using is normally: hour wheel and the day-date wheel load structure that is integrated, and coaxial rotation, date finger driving wheel and change a day shifting block pressing and be structure as a whole, and coaxially freely rotate, date wheel with change a moon shifting block pressing and be structure as a whole; Its principle of work is: the transmission of basic movement drives hour wheel and the day-date wheel rotates, day-date wheel and date finger driving wheel engagement, make change day shifting block promote date wheel and with the date wheel pressing be moon shifting block that changes of one, the described moon shifting block that changes promotes monthly calendar wheel, finishes the change of monthly calendar.But this structure generally is subjected to the restriction of calendar, monthly calendar position, makes the train part more, and area occupied is bigger, is not suitable for increasing additional function.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of simple in structure, is convenient to processing, takies the few wrist-watch monthly calendar mechanism in movement space.
The technical scheme that the utility model adopted is: a kind of monthly calendar mechanism of wrist-watch, comprise hour wheel, day-date wheel, sun-changing wheel, change a day shifting block, date finger driving wheel retaining nail, date wheel sheet, date wheel nail, day backstay, bearing spring, change a month nail, day jumper spring, monthly calendar wheel, month backstay and the moon jumper spring; Described hour wheel and day-date wheel load are integrated, and coaxial rotation, and described sun-changing wheel is an one with changing a day shifting block pressing, coaxial independent rotation respectively, and described sun-changing wheel and the engagement of day-date wheel are fixed with retaining and follow closely on the described sun-changing wheel; Described date wheel sheet is provided with the date wheel nail; Be formed with groove on the described day backstay, the described month nail that changes is arranged in the groove, and the baseplane screw of day backstay is provided with bearing spring between month following closely with changing; Jumper spring, monthly calendar wheel were installed on the big pad by screw in described day, and jumper spring passed through month backstay to monthly calendar wheel location in described month.
The groove that formed on the backstay in described day is a rectangular slot.
The day-date wheel is 1: 2 with the gear ratio of date finger driving wheel.
The beneficial effects of the utility model are: owing to utilize the movement locus that returns the Sino-Japan backstay of calendar, stir the monthly calendar gear teeth, finish moon process of changing.This novel structure is simple, is convenient to manufacture, and processing cost is low, and it is few to take the movement space, is convenient to increase other additional function.
