Abstract

The utility model relates to a calendar indicator. An hour wheel of a clock movement is sheathed with a year wheel, and a wheel shaft is sheathed with a calendar needle which is longer than a second hand. The place between the hour wheel and the year wheel is provided with a gear transmission mechanism with the speed reducing ratio of 365: 1 or 730: 1. The outer margin of a dial disc is provided with date scale lines, week scale lines and month scale lines, which continuously form calendar scale rings of one year. The utility model has the advantage that years, months, dates and weeks can be clearly and continuously indicated by the same indicating needle.

Description

The minute hand calendar indicating device of clock and watch

The utility model belongs to timer, relates to the calendar indicating device of timer.

Clock and watch and even wrist-watch are gone through function its even-numbered days and only are week and date, and wherein pointer structure is half pin type.It exists following defective, and a pointer can not indicate go through above-mentioned even-numbered days simultaneously, does not also have to link up clearly to indicate the characteristics of a calendar, and therefore existing half pin type calendar structure can not satisfy people's needs.

The purpose of this utility model provides the minute hand calendar indicating device that a kind of same pointer can link up, clearly indicate the clock and watch in year, month, day, week.

Above-mentioned purpose is achieved through the following technical solutions: the hour wheel of watch core is set with the annual ring that is supported by the annual ring spring, this axle sleeve of taking turns is equipped with the date hand of being longer than second hand, be provided with the reduction gearing gear train between hour wheel and the annual ring, the outer rim of dial plate be provided with by date groove, week groove and month the calendar calibration loop formed continuously of groove.

The ratio of gear of the reduction gear between said hour wheel and the annual ring, dial plate was 365: 1 in 24 hours, dial plate was 730: 1 in 12 hours.

A said calendar calibration loop is the combination of different year concentric scale ring.

Below with embodiment and description of drawings the utility model thereof.

Accompanying drawing 1 embodiment index dial structure synoptic diagram.

Accompanying drawing 2 embodiment watch core partial structurtes synoptic diagram.

Shown in Figure 1, the outer rim of timepiece dial 14 is provided with the concentric scale ring combination of the calendar calibration loop 15 in 3 years, each calendar calibration loop is by the date groove, week groove and month groove and corresponding digital form continuously, date hand 10 is for being longer than the minute hand of second hand 7, its rotation and hour hands 9, minute hand 8 are synchronous, and minute hand can clearly be indicated date, week and month then, and are the indications that links up.

Fig. 2 is a date hand driving mechanism synoptic diagram, and train wheel bridge 2 tops of watch core 1 are provided with this mechanism.In the prior art, minute wheel 12 by back gear 11 with the watch core transmission of power in hour wheel 13, with reduction gearing gear train 3 its engagement and that support by train wheel bridge 2 auxiliary splints 4 watch core power is transmitted to annual ring 5 simultaneously, annual ring is set in hour wheel and is supported by annual ring spring 6, the axle sleeve of annual ring is equipped with date hand 10, and the aligning gear utilization of date hand has hour wheel, minute wheel aligning gear now.

Reduction gearing gear train 3 its ratio of gear among Fig. 2 should cooperate the dial plate timing range, 24 hours dial plates take turns at that time with the annual ring ratio be 365: 1, the ratio of gear of 12 hours dial plates is 730: 1.

The utlity model has following advantage: 1 dial plate and pointer are neatly clear. 2, date hand Then annual calendar and easy to use of clear indication can link up.

Claims
