Permanent perpetual calendar structure of clock

Abstract

According to the permanent perpetual calendar structure of the clock, every time the 48-tooth month driving wheel rotates by one circle, namely, the 48-tooth month driving wheel rotates by one circle every four years, the number of days of each month can be calculated through the depth of wheel teeth of the 48-grid big and small month identification wheel, and when the 48-tooth month driving wheel rotates by 25 circles, and the 25-tooth leap year ring rotates by one circle, the number of days of each month can be calculated through the depth of wheel teeth of the 48-grid big and small month identification wheel. In the past 100 years and four hundred years, the four surfaces of the big and small month wheel are provided with three concave surfaces and one convex surface which are aligned with the opening of the 48-grid big and small month identification wheel, the concave surfaces are aligned with the opening of the 48-grid big and small month identification wheel, the depth is increased from 29 days to 28 days, and'no leap leap is achieved every one hundred years, and the unique convex surface is aligned with the opening of the 48-grid big and small month identification wheel, namely 29 days and 28 days, so that the leap leap leap is achieved. The perpetual calendar is simple in structure, high in reliability and low in manufacturing cost, and the perpetual calendar structure does not need to be adjusted permanently and can be realized only by adding six parts.

Description

Technical Field

[0001] The utility model relates to the technical field of clocks and watches, in particular to a permanent calendar structure of a clock and watch. Background Art

[0002] Clocks with calendar functions have always been popular among consumers. According to the existing calendar, a common year has 365 days, a leap year has 366 days, a leap year has one leap year every four years, a leap year has no leap year every 100 years, and a leap year has another leap year every 400 years. A long month has 31 days, a short month has 30 days, and February has 28 or 29 days. Usually, calendar watches cannot display long and short months and leap years, and need to adjust the date at the end of the month. Or, although they can display a common year, leap year, and long and short months, they cannot distinguish between a leap year every 100 years and a leap year every 400 years, which is inconvenient for users. Therefore, it is necessary to further improve the calendar display mechanism of clocks and watches. Utility Model Content

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0020] In order to realize a perpetual calendar structure that does not need to be adjusted permanently on a clock, the specific contents of the utility model are as follows.

[0021] Combination Figure 1 and Figure 2 As shown, the embodiment of the utility model is a perpetual calendar structure for a watch, which importantly includes a push rod assembly 4 rotatably arranged on a bottom plate 1 and linked to a 24-hour lever 3 on a 24-hour wheel 2 of a movement on the left side, a month wheel assembly 5 rotatably arranged on the bottom plate 1 and linked to the right side of the upper end of the push rod assembly 4, and a calendar wheel assembly 6 rotatably arranged on the bottom plate 1 and linked to the lower end of the push rod assembly 4. The calendar wheel assembly 6 is linked to the moon lever 9 on the moon wheel 8 by sequentially engaging a transmission wheel 7, and the transmission wheel 7 engages a moon wheel 8, and then the moon wheel assembly 5 is linked to the moon wheel assembly 5;

[0022] The moon wheel assembly 5 comprises a 48-tooth moon driving wheel 501, a 12-tooth moon wheel 502 rotatably disposed on the bottom plate 1 and meshing with the 48-tooth moon driving wheel 501, a 48-grid month identification wheel 503 fixedly disposed on the 48-tooth moon driving wheel 501 and rotating therewith, a 400-year wheel driving wheel 504 rotatably disposed on the side of the 48-tooth moon driving wheel 501, a 400-year wheel driving rod 505 fixed on the bottom plate 1 and aligned with the 400-year wheel driving wheel 504, and a 12-tooth moon wheel 502 rotatably disposed on the bottom plate 1 and meshing with the 12-tooth moon wheel 501. a 25-tooth 400-year leap year wheel 506 meshed with the driving wheel 504, a leap year identification cross wheel driving wheel 507 fixedly arranged on the central axis of the 25-tooth 400-year leap year wheel 506 and not rotating, a leap year identification cross wheel 508 rotatably arranged on the side of the 25-tooth 400-year leap year wheel 506 and correspondingly toggled by the leap year identification cross wheel driving wheel 507, and a 400-year large and small moon wheel 509 fixed to the bottom 508 of the leap year identification cross wheel and located on the other side of the 25-tooth 400-year leap year wheel 506 and rotating together with the leap year identification cross wheel 508;

[0023] A monthly indication mechanism 510 is fixedly arranged at the center of the 12-toothed moon wheel 502. The four sides of the 400-year moon wheel 509 have three concave surfaces and one convex surface aligned with the opening of the 48-grid large and small month identification wheel 503.
