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

Small three needle calendar mechanical watch

The utility model relates to a small three-hand calendar mechanical watch, which relates to the modification of the mechanical watch.

A common wristwatch takes the center of the dial as the axis, and uses three coaxial hands to indicate the hours, minutes, and seconds around the dial, while the date is displayed by the rotating numbers in the calendar window. Along with the development of society, the forms of people's demands for watches are also diversified, such as, even the mode of displaying the day and the month is also displayed separately by rotating the pointer on the dial to indicate the numbers around each circle.

The purpose of the utility model is to provide a small three needle calendar mechanical watch which can be composed of several groups of pointers on a surface plane at the same time, wherein the axes of the hour hand 19 and the minute hand 20 are still maintained at the center 22 of the dial 30. The pointer-type small calendar is placed on the line between the 12th position of the dial 30 and the center of the dial. The power of the calendar pointer is transmitted from the hour wheel 17, and is decelerated by the date-changing wheel 16 to 1 revolution/24 hours, and then drives the date-changing cam 15. When one tooth on the calendar wheel 10 is turned every day, the small calendar pointer 22 closely matched with the calendar wheel shaft 11 will rotate accordingly, pointing to the calendar scale 28 printed on the dial 30, so as to display the date of each day; The second display pointer is placed on the connection line between the 6-digit position of the dial 30 and the center of the dial. At the same time, the power of the second hand 18 is transmitted from the four-wheel pinion 2, and its speed is 1 revolution per minute. On the second wheel 1 part, up to the second hand 18 connected to it.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of small three needle calendar mechanical watch described in the utility model;

Fig. 2 is the transmission schematic diagram of the small three needle calendar mechanical watch of the utility model;

Fig. 3 is a schematic diagram of the small three-hand calendar mechanical dial of the present invention.

As shown in Figures 1, 2, and 3, the small three-hand calendar mechanical watch of the utility model is composed of four sets of pointers: hour, minute, second, and day, and the axes of the pointers 19 and 20 that represent the hour and minute are still maintained on the dial. At the center position of 30, the so-called pointer-type small calendar is placed on the connection line between the 12-digit position of the dial 30 and the center of the dial. The power of the calendar pointer 22 is rotated by the hour wheel 17, and decelerated by the date-changing wheel 16 to 1 revolution. / 24 hours, then drive the day-changing cam 15 to reach a tooth on the calendar wheel 10 every day, the small calendar pointer 22 closely matched with the calendar wheel shaft 11 will also rotate thereupon, pointing to the calendar dial printed on the dial 30 28. Use this to display the date of each day; the so-called second display pointer 18 is placed on the line connecting the 6-digit position of the dial 30 and the center of the dial, and the power of the second hand 18 is transmitted from the four-wheel gear shaft 2, and its speed is 1 revolution The minute/minute is transmitted to the second wheel part 1 through the passing wheel part 3, until the second hand 18 connected thereto.

As shown in Figure 1, in the small needle calendar device of the said small three needle calendar mechanical watch of the utility model, the hour wheel 17 is engaged with the date change wheel 16, the date change wheel 16 is coaxial with the date change cam 15, and the date change cam 15 and the date change camshaft 12 are clearance fits, and the day change cam 15 is driven by the pin 14 on the date change wheel 16 to rotate together. Simultaneously, in the small needle calendar quick-dial mechanism, the connection between the calendar wheel 10 and the wrist watch head 5 is pushed by the quick-dial cam 4 to a calendar quick-dial lever 6 in the shape of a phoenix head. Under the effect of the function, the calendar fast dial lever 6 is not in contact with the calendar wheel 10 and is in the state of preparing for fast dialing. The calendar positioning lever 9 is positioned for the calendar wheel 10 below the calendar positioning spring 8; because there is a groove 13 at the contact of the date changing cam 12 and the pin 14, there is a certain degree of freedom between the two, and when the calendar is dialed quickly, it can be Avoid the occurrence of the phenomenon of the date changing cam 15 and the calendar wheel 10 top teeth.

As shown in Figures 2 and 3, the power of the common second hand 21 is transmitted by the mainspring 23, and is transmitted to the escapement governor A of the watch through the center wheel part 24, the three-wheel part 26, and the four-wheel part 27. The role of the system to produce constant speed rotation. And pass back three-wheel parts 26 by four-wheel parts 27, passed to the second pinion shaft 25 on the central position of watch at last, drives original center second hand 21 to rotate. And what the present utility model adopted now is the off-centre second wheel part 1, although its power transmission path is the same, after the constant speed rotation of the escapement governor A is passed to the four-wheel part 27, it does not start from the three-wheel part 26. Pass out, but pass on the second wheel part 1 through the four-wheel gear shaft 2 and the passing wheel part 3, so that the second hand shaft can be placed at any position other than the central axis of the watch, not coaxial with the hour and minute hands, giving people The visual senses produce a sense of freshness.

Adopting the structure of the small three-needle calendar mechanical watch described in the utility model not only can make the time display structure of the calendar simple, reliable in operation, and fresh in vision, but also has no restricted area for the calendar quick-dial mechanism, which is convenient for people to use, and at the same time The representation of each time is clear at a glance, has its unique features, and satisfies people's various preferences. In addition, for the structure of the day and second display in the utility model, the positions of the second and day pointers can also be set at other positions of the dial besides the 12-character position and the 6-character position of the dial, thereby producing Watches with different visual effects. This structure described in the utility model can also be widely used in various watch structures that adopt pointer indications such as mechanical men's and women's watches, automatic mechanical watches, and pointer quartz watches, and can even be used in the structure of clocks.
