Abstract

The utility model relates to a small three-pointer calendar mechanical watch which is composed of an hour hand, a minute hand, a second hand and a date hand. Shaft centers of the hour hand and the minute hand are positioned at a central position of a watch dial, and an indicating hand type calendar is positioned on center lines of 12 digital positions and the watch. Dynamic force the indicating hand type calendar is transmitted by an hour wheel, and a speed is decreased to one circle / 24 hours by passing through a date changing wheel. Then the date changing wheel is driven, and a show circle of seconds is arranged on the central line of the 6 digital position and the watch dial. The dynamic force of the show circle of seconds is transmitted by a four-wheel gear shaft, and the second hand arranged on a second wheel is transmitted with the speed of one circle / minute through a setting wheel component. A mechanical watch, a mechanical automatic watch and an indicating hand type quartz clock by adopting the structure of the utility model have the advantages of simple display structure, reliable work and clear visual sensation. No work exclusion area exists when the date digital of a calendar quick shifting mechanism is changed, and the utility model can also be used on a clock structure.

Description

Little three pin calendar stem-winders

A kind of little three pin calendar stem-winders relate to the remodeling of mechanical watch.

Common wrist-watch is to be the axle center with the dial plate center, and when indicating dial plate periphery numeral to show with three coaxial pointers, minute, second, the date is then shown by the rotation numeral in the date window.Along with the development of society, people's demand wrist-watch form is variation also, as, the mode of demonstration day, month is also rotated each circumferential edge numeral of indication with pointer and is shown respectively on dial plate.

The purpose of this utility model provides a kind of little three pin calendar stem-winders that can form with several groups of pointers simultaneously on a surface plane, wherein hour hands 19, the axle of minute hand 20 still maintain dial plate 30 on 22 heart positions, the little calendar of said pointer-type then places on 12 word bits and the dial plate line of centres of dial plate 30, the power of calendar indicator is spread out of by hour wheel 17, being decelerated to 1 by date finger driving wheel 16 changeed/24 hours, drive again and change day cam 15, when reaching 1 tooth stirring every day on the date wheel 10, rotate with date wheel shaft 11 friction tight calendar little finger of toe pins 22 thereupon, point to the calendar scale 28 that is printed on the dial plate 30, show the date of every day with this; Said second display pointer places on 6 word bits and the dial plate line of centres of dial plate 30, and the power of second hand 18 is spread out of by four-wheel tooth axle 2 simultaneously, and its rotating speed is 1 rev/min, is delivered on second wheel 1 parts, until coupled second hand 18 by crossing wheel component 3.

Below in conjunction with accompanying drawing in detail structure of the present utility model is described in detail:

Fig. 1 is the structural representation of little three pin calendar stem-winders described in the utility model;

Fig. 2 is the transmission synoptic diagram of little three pin calendar stem-winders described in the utility model;

Fig. 3 is little three a pin calendars machinery dial plate synoptic diagram described in the utility model.

As Fig. 1,2, shown in 3, the said little three pin calendar stem-winders of the utility model by the time, divide, second, day, four groups of pointers were formed, when wherein representing,

minute pointer

19,20 axle still maintains on the center of dial plate 30, the little calendar of said pointer-type then places on 12 word bits and the dial plate line of centres of dial plate 30, the power of calendar indicator 22 is produced by hour wheel 17, being decelerated to 1 by date finger driving wheel 16 changeed/24 hours, drive again and change day cam 15, when reaching tooth stirring every day on the date wheel 10, also rotate with date wheel shaft 11 friction tight calendar little finger of toe pins 22 thereupon, point to the calendar index dial 28 that is printed on the dial plate 30, show the date of every day with this; Said second display pointer 18 places on 6 word bits and the dial plate line of centres of dial plate 30, and the power of second hand 18 is spread out of by four-wheel tooth axle 2, and its rotating speed is 1 rev/min and is delivered on the second wheel parts 1 by mistake wheel component 3, until coupled second hand 18.

As shown in Figure 1, in the little pin calendar device of the said little three pin calendar stem-winders of the utility model, hour wheel 17 is meshed with date finger driving wheel 16, date finger driving wheel 16 is with to change day cam 15 coaxial, change day cam 15 and change day camshaft 12 and be clearance fit, drive by the pin on the date finger driving wheel 16 14 and change day cam 15 and rotate together.Simultaneously, in little pin calendar quick pulling mechanism, a fast driving lever 6 of calendar that is the phoenix head is dialled in being connected by fast advance cam 4 tops of date wheel 10 and wrist-watch crust 5, and under the effect of the restoring force of the fast dialing spring 7 of calendar, the fast driving lever 6 of calendar does not contact group state soon of preparing that is in date wheel 10 at ordinary times.Date indicator jumper 9 is date wheel 10 location below calendar back stop 8; With pin 14 contact positions individual groove 13 is arranged owing to change day cam 12, level of freedom is arranged between the two, when calendar is dialled soon, can avoid changing the generation of day cam 15 and date wheel 10 apical tooth phenomenons.

Shown in Fig. 2,3, the power of common second hand 21 is to be spread out of by clockwork spring 23, passes to the escapement speed regulator A of wrist-watch through centre wheel parts 24, three wheel components 26, four-wheel parts 27, rotates because the effect of A makes system produce constant speed.And pass three wheel components 26 back by four-wheel parts 27, and finally passed to the second pinion 25 on the center of table, drive original center second 21 and rotate.And the utility model employing now is off-centre second wheel parts 1, though its power efferent pathway is identical, but after four-wheel parts 27 are passed in the constant speed rotation of escapement speed regulator A, do not spread out of from three wheel components 26, but pass on the second wheel parts 1 through four-wheel tooth axle 2, mistake wheel component 3, thereby can be placed in optional position beyond the central shaft of table to second hand axle, not with the time, divide coaxial needle, produce feeling of freshness for people's visual perception.

Adopted the structure of little three pin calendar stem-winders described in the utility model, simple in structure, reliable operation in the time of not only can making calendar apparent, vision is pure and fresh, and the calendar quick pulling mechanism worked for no forbidden zone, made things convenient for people's use, the expression of each time simultaneously comes into plain view, and its unique distinction is arranged, and has satisfied the various hobbies of people.In addition, said this day, the structure that second shows of the utility model, its second, day pointer position can also be arranged on other position of dial plate near 12 word bits that can be arranged on dial plate and 6 word bits, thereby produce the wrist-watch of different visual effects.This structure described in the utility model can also be used widely in the watch structure of various employing pointer indications such as machinery man, women's dress wrist-watch, automation table and analog-type quartz crystal watch, even can be used on the structure of clock.
