Description

Calendar and phase display for watch

The utility model relates to a kind of table day phase calendar display apparatus.This device can be attached on the various tables of pointer indication, the table machine of additional this device, realizes in can be when normally walking day mutually and calendar shows, and indicates the time of 24 o'clock systems.

Realized in the past at the utility model that wrist-watch day mutually and the calendar demonstration, mostly adopt hour wheel and day to add a duplicate gear between the wheel mutually, one take turns with hour wheel engagement, another is taken turns and day wheel and dial the double reduction mechanism of sun engagement mutually, its number of parts is many, difficulty of processing is big; And a day phase wheel component mostly is to be arranged in table machine central authorities, installs on taking turns mutually day and coils mutually a day, be not easy to the time indication of additional 24 o'clock systems, otherwise the thickness increase of his-and-hers watches machine is bigger.

The purpose of this utility model is to provide a kind of wrist-watch of eliminating above-mentioned defective, has not only realized day mutually and calendar shows, but also can indicate time of 24 o'clock systems, has also simplified gear train, and has made the little one-level reduction gear of table machine thickness increase.

For achieving the above object, table of the present utility model links a date driver with day phase calendar display apparatus rigidity on the hour wheel of general wristwatch, this is taken turns also can mould cast solid with hour wheel, it with the step-down ratio of 2:1 drive simultaneously a day phase wheel component and one dial per 24 hours moving turning around of the sun; Turn over date rings, every day that the sun stirs 31 teeth or 30 teeth and be printed on 1～31 or 1～30 printed words a tooth pitch by dialling again.The day mutually the wheel be packed in its rotating shaft, wheel face be separated by 180 the degree be printed on the Sun and the Moon pattern, can show solar pattern at 6 o'clock to 18 o'clock every day, 18 o'clock to second day 6 can show moon pattern; The day phase wheel component that installs is bearing in the driving hole of bottom plate, between the sheet wheel spring of doing archwise is contained in dial plate and day takes turns mutually, has not only avoided day phase wheel face and dial plate friction, but also has avoided day mutually wheel shaft to play.Can demonstrate day mutually and the calendar variation by the window on the dial plate like this, and by being installed in the time that pointer on day phase wheel shaft can indicate 24 o'clock systems; On dial plate, be the center by the scale character code that counterclockwise stamps 24 o'clock systems with the center of taking turns mutually day.

The utility model is that driving wheel drives day phase wheel component and dials the sun because increased a date driver on hour wheel, so reduced the plane occupancy of day phase calendar mechanism greatly, also little to the movement thickness effect, be convenient to be attached on the wrist-watch of different size, especially be 6 * 8 to make on the woman's watch additional this device at the movement planar dimension, be assembled into oval-shaped day phase calendar woman's watch and just more seem small and exquisite, graceful magnificent.Wrist-watch behind additional this device, comparing with the generic calendar wrist-watch only increases day wheel component (comprise day wheel and wheel shaft) mutually and pointer mutually, it is simple in structure, part is few, function is many, is convenient to more renew function and new pattern, is a kind of more satisfactory wrist-watch additional mechanism providing additional operation.

Accompanying drawing is represented an embodiment of the present utility model.

Fig. 1 represents assembled watch outward appearance planimetric map of the present utility model.

Fig. 2 represents movement planimetric map of the present utility model.

Fig. 3 represents localized axial stretch-out view of the present utility model.

Above-mentioned three accompanying drawings all are to make the pointer quartz woman that table is that example is carried out additional design with 6 * 8 of wrist watch plant, Yantai production, are described in further detail below in conjunction with accompanying drawing again.

A. wheel component (1) during calendar: with reference to the accompanying drawings 2 and 3, wheel component during calendar (1) is to be installed on the hour wheel (2) by date driver (3) to constitute, both link together at rigidity.

B. day phase wheel component (4): with reference to the accompanying drawings 2 and 3, a day phase wheel component (4) is to install in its rotating shaft (6) and constitute by taking turns (5) day mutually; The day phase wheel component (4) that installs is bearing in the driving hole of bottom plate parts (7), takes turns mutually in day on the wheel face of (5), and the corresponding tables card is printed on the Sun and the Moon pattern respectively, a formation day phase display panel every 180 °; Sheet is arc takes turns spring (15) and is contained in day mutually between wheel (5) and the dial plate (8).

C. dial plate (8): with reference to the accompanying drawings 1 and 3, on dial plate (8), corresponding day, the pattern on wheel (5) and the date rings (9) and calendar character processed respectively day mutually and a date-indicator window mouth mutually; And the center of rotation with day phase wheel component (4) is the center, by the scale printed words that counterclockwise stamp 24 o'clock systems equably.

D. operating principle: with reference to the accompanying drawings 2 and 3, date rings (9) is that it is radially spacing and be its axial limiting with calendar cover plate (11) with calendar location-plate (10).Along with the normal operation of basic movement, date driver (3) drives day wheel (5) and dial the sun (12) and transported in per 24 hours and turn around mutually simultaneously with the step-down ratio of 2:1.Usually tooth and the date rings of dialling on the sun (12) (9) has certain radial play, has only a long tooth can stir date rings (9) and rotates; When the long tooth shifting block on dialling the sun (12) is stirred date rings (9) rotation, date rings (9) forces date indicator jumper (13) to lift gradually and compresses date indicator jumper spring (14) and elastic deformation takes place, store deformation energy, when date indicator jumper (13) comes back tooth top to date rings (9), date indicator jumper spring (14) just discharges its deformation energy, make backstay (13) promote date rings and rotate a tooth pitch forward, thereby the calendar on the dial plate window is just changed one day.Because a day phase wheel component (4) turned around in per 24 hours, just can directly indicate the time of 24 o'clock systems so be installed in the pointer (16) of taking turns mutually in the rotating shaft (6) day, and on the window of dial plate (8), demonstrate the day phase change situation of expression the Sun and the Moon again.
