Abstract

The utility model relates to a movement for wristwatch, consisting of an hour wheel 15, a day wheel exchange component 20, a day calendar wheel component 5 and a week calendar wheel component 13. The utility model is characterized in that: the week calendar wheel component 13 is meshed with the hour wheel 15 through a week wheel exchange component 11; a week calendar putting-forward cam 12 and a week putting-forward cam 9 are coaxially arranged on a week exchange wheel blade 7; a week calendar putting-forward bar 6 is fixedly arranged on the right of the week exchange wheel blade 7 and is arranged inside a putting-forward opening which is insertedly connected with the week calendar putting-forward cam 12. By adoption of the structure of the utility model, a week calendar putting-forward press-button can be arranged on the right of a wristwatch tray, thereby being convenient to use by a great mass of people who use right hands to operate; and because the week putting-forward cam or day putting-forward cam is movably sleeved on respective wheel axle, so the two cams can perform automatic collision avoidance when the week calendar or the day calendar is put forward, thereby the occurrence of apical tooth phenomenon is avoided when the week calendar or the day calendar is put forward and the service life of the wristwatch is prolonged.

Description

Timepiece movement

A kind of timepiece movement relates to the structure of the timepiece movement of multiple demonstration.

In No. 95207374.9 patents, a kind of seven pin stem-winder cassette mechanism structures were once disclosed, in the time of can showing simultaneously, every minute and second, 24 hours, calendar, go through in week and the monthly calendar indication, for reducing transmission link, adopted a kind of meshed transmission gear mode of flush system, but when fast group of key gone through in processing week, can only be arranged in the left side of wrist-watch, this is for the personage of general custom right-hand operated, can feel some inconvenience, simultaneously, day (or dialling week) cam of dialling in the past is to be fixed tightly on the same axle, when fast quick change day (or changing week) with changing day (or changing a week) wheel, press fast driving lever, cam can't be avoided with gear, thereby the apical tooth phenomenon easily takes place, severe patient even injuring part and make the fast system down of dialling.Therefore, in most of the cases, the producer can warn in instructions, and (22:00 that is every day is to the 2:00 scope of next day) bans use of the fast button of dialling to the caveat user in the Zhou Shiqu changing day or change, and makes troubles to the user.

The purpose of this utility model is to provide a kind of timepiece movement, when guaranteeing between each part of movement that gearing is compacter, eliminates and changes day or change the use forbidden zone of all mechanisms, moves on to the wrist-watch right side, convenient general personage's use going through the fast button of dialling week simultaneously.

The utility model is to implement like this: in the timepiece movement of being made up of hour wheel 15, date finger driving wheel assembly 20, date wheel parts 5, day star with disk 13, wherein said day star with disk 13 is by week-changing wheel assembly 11 and hour wheel 15 engagements, all cam nails 8 of dialling on the week-changing wheel sheet 7 promote to dial all cams 9, dial all cams 9 and go through fast advance cam 12 week and be enclosed within versatilely on the week-changing wheel axle 10, go through the right side that fast driving lever 6 is fixed on week-changing wheel sheet 7 week, its end directly and go through fast advance cam 12 activities week and join.

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

Fig. 1 is a kind of dial plate synoptic diagram that has adopted timepiece movement described in the utility model;

Fig. 2 is the planimetric position synoptic diagram of timepiece movement structure described in the utility model;

Fig. 3 is a week-changing wheel assembly synoptic diagram in the timepiece movement structure described in the utility model;

Fig. 4 is Fig. 3 axial arrangement synoptic diagram.

As shown in Figure 1, adopted the movement of structure described in the utility model, its Watch dail plate can adopt full pointer to show, can see intuitively like this under the same time the time, the real-time number under the minute, second, 24 o'clock systems and residing date, number of weeks, simultaneously, go through the fast right side that button 4 is placed in Watch dail plate 1 front of dialling week, made things convenient for general custom to make right-handed personage.

As shown in Figure 2, the said timepiece movement of the utility model is made up of hour wheel 15, date finger driving wheel assembly 20, date wheel parts 5, day star with disk 13, wherein, said day star with disk 13 is by week-changing wheel assembly 11 and hour wheel 15 engaged transmission, overlapping versatilely on the week-changing wheel axle 10 of week-changing wheel sheet 7 and going through fast advance cam 12 week and dial all cams 9, cam on the week-changing wheel sheet 7 is followed closely 8 actuating cams 9, simultaneously, go through the right side that fast driving lever 6 is fixed on week-changing wheel sheet 7 week, its end from the movement right side directly and go through fast advance cam 12 activities week and join.

As shown in Figure 3, the said timepiece movement of the utility model, can also make big garden shape dialling all cams 9, having a fan-shaped window 23 near circle centre position, be connected with it by all cam nail of dialling on the week-changing wheel sheet 78, when dialling all cams 9 and stir tooth on the week calendar wheel sheet 14 with 1 time/24 hours speed, the pointer 3 that is installed on the day star with disk 13 rotates thereupon, and what be printed on the sensing Watch dail plate 1 goes through scale 2 week.

As shown in Figure 4, adopting big garden shape to dial under the form of all cams 9, equally can be going through fast advance cam 12 week of week-changing wheel assembly 11, dial all cams 9, being sleeved on the week-changing wheel axle 10 versatilely.

Because the utility model adopts week to go through the right side that fast driving lever 6 is fixed on week-changing wheel sheet 7 versatilely, the other end reaches the right side edge of Watch dail plate 1, going through the fast button 4 of dialling week touches mutually with its activity, add that dialling all cams 9 is to be actively set on the week-changing wheel axle 10, during operate as normal, reach the purpose of changing week by all cam nail 8 promotion group all cams 9 of dialling on the week-changing wheel sheet 7, go at hour hands and to change in the Zhou Shiqu (general wrist-watch all is arranged on the 22:00 of every day between the 2:00 of next day), if need be by pressing when going through fast driving lever 6 week, dialling all cams 9 can follow automatically and move forward, thereby avoided touching mutually the generation of the situation of answering back to, accomplished to dial soon the Zhou Liwu forbidden zone with the gear teeth of week calendar wheel sheet 14.

In like manner, in the said timepiece movement of the utility model, as shown in Figure 2, date wheel parts 5 are by crossing calendar thumb wheel 22, date finger driving wheel assembly 20, day wheel component 16 and hour wheel 15 engagements, cam nail 17 on the date finger driving wheel 18 promotes to dial a day cam 19, dial day cam 19 and be sleeved on structure on the date finger driving wheel axle 21 versatilely, do not dial the generation that day cam 19 and the tooth of calendar thumb wheel 22 touch the top phenomenon mutually thereby can not produce when wrist-watch is dialled soon in changing day time zone, when fast group of calendar, do not have the forbidden zone, more can not cause the situation of changing day part injury.

Adopted timepiece movement described in the utility model, because all cams 9 of dialling of the said Zhou Li of being used for are gone through the fast advance cam 12 coaxial structures that are installed on the week-changing wheel axle 10 with week, both reduce the part flush system and arranged shared plane space position, be placed on this position going through fast driving lever 6 week, make and go through the fast button 4 of dialling week and can inlay the right side of putting at Watch dail plate 1, made things convenient for the people of most of right-handed work to use, owing to change week, the device that changes day all can adopt and be assemblied in versatilely on separately the wheel shaft dialling week (or dial day) cam, thereby can accomplish not have the forbidden zone and dial Zhou Li (or calendar) soon, prolong the serviceable life of wrist-watch.
