The mechanism has the advantages that the date indication is clear with novel design; no working forbidden zone exits when adjusting; the fast advance mechanism of rocking-plate type increases the efficiency of fast advance and the precision; the location device with integrated rod and spring simplifies the structure and increases the location precision.

Description

The pointer calendar mechanism of wrist-watch

Technical field: the utility model relates to a kind of timer, specifically refers to the improvement of the calendar mechanism in a kind of multiple-pin type stem-winder.

Background technology: traditional mechanical window formula calendar watch adopts lettering on little date rings, shows date at dial plate uplifting window mouth, and manufacture craft is complicated, and font is also big inadequately.If use the magnifier enlarge font, then operation and cost increase.Quick for adjusting, setting up has easy fast dialing device, but there is the work forbidden zone in general fast dialing device, needs to fall to dial to allow earlier a tooth during adjustment, suitable again dialling when just not influencing.

Summary of the invention:

The utility model proposes a kind of new pointer calendar mechanism, the date numeral in the calendar mechanism of spininess stem-winder be imprinted on the dial plate periphery, and with one be located on the movement central shaft big pointer indication, make the date indication clear, table fashionable; Utilize rocking plate type architecture advances fast dialing device simultaneously, improved fast efficient and the fast precision of dialling dialled; And a kind of sun-changing head that utilizes incomplete gear mechanism that does not have the work forbidden zone proposed; In addition, the locating device of improved pole spring unification can be simplified the structure of detent mechanism, improves bearing accuracy.

The pointer calendar mechanism of a kind of wrist-watch of the present utility model, mainly comprise hour wheel, day third wheel, date finger driving wheel, sun-changing head, date wheel, fast dialing device and locating device, wherein the date numeral in the calendar mechanism is located at the dial plate periphery, and with a big pointer indication, this big pointer is located on the date wheel that is positioned on the movement central shaft.

The driving-chain of described date wheel is followed successively by hour wheel, day third wheel, date finger driving wheel, sun-changing head, date wheel; Wherein, hour wheel drives date finger driving wheel by day third wheel, and is provided with sun-changing lamp promotion sun-changing head by date finger driving wheel, and sun-changing head is the partial gear that has only a tooth, and described sun-changing lamp is by promoting this sun-changing head 5 and then date wheel 2 being dialled a tooth.

Described fast dialing device by footstalk, draw shelves, trip(ping) lever, rocker, transmission wheel, castle wheel, dial third wheel soon and fast-dialing wheel is formed; Wherein draw shelves, trip(ping) lever and rocker to constitute the rocker structure, to realize this fast dialing device and date wheel engagement and quick drop out of gear fast.

Described locating device adopts the backstay of pole spring unification.This backstay is made by a rubber-like reed, and an end of this reed is fixed on the clamping plate, and other end inlay card is in the gear teeth of date wheel.

The advantage of pointer calendar mechanism of the present utility model is:

1. with the former date numeral that is imprinted on the little calendar-disc, change the periphery that is located at dial plate, because the diameter of dial plate periphery is bigger with the date window demonstration, this has just amplified the numeral on date greatly, and, making the date indication very clear with the pointer indication, the style of table is also relatively more novel;

2. in the transmission of calendar mechanism, adopt the sun-changing head of partial gear, do not have the work forbidden zone during adjustment;

3. its fast dialing device adopts the rocking plate type structure, has improved fast efficient and the fast precision of dialling dialled;

4. the locating device of improved pole spring unification has been simplified the structure of detent mechanism, and the elasticity during work is soft moderate, has improved bearing accuracy.

Description of drawings:

Fig. 1 is the structural representation of an embodiment of the present utility model.

Embodiment:

An embodiment of the present utility model as shown in Figure 1.Its calendar mechanism is made up of hour wheel 1, date wheel 2, day third wheel 3, date finger driving wheel 4, sun-changing head 5.Wherein, hour wheel 1 drives the wheel 3b of lower floor of day third wheel 3, drive date finger driving wheel 4 by upper strata wheel 3a again, date finger driving wheel 4 is provided with sun-changing lamp 4b, stir date wheel 2 by sun-changing lamp 4b promotion sun-changing head 5 and turn over a tooth, be one, and be positioned at the big pointer 15 that the date of indication surface periphery is housed on the date wheel 2 on the movement central shaft.Described sun-changing head 5 is for having only the partial gear of a tooth, described sun-changing lamp 4b and 5 engagements of this sun-changing head.

Described fast dialing device by footstalk 7, draw shelves 8, trip(ping) lever 9, rocker 10, transmission wheel 11, castle wheel 12, dial third wheel 13 soon and fast-dialing wheel 14 is formed, wherein draw shelves 8, trip(ping) lever 9 and rocker 10 to constitute and realize that described adjusting gears and date wheel 2 mesh fast and the rocker structure of quick drop out of gear.Its concrete structure is: the square tenon 7a in the left side of arbor 7 goes up to slide and establishes a castle wheel 12, and the middle part of this castle wheel 12 is provided with annular groove, and its left end is provided with straight-tooth; Draw the middle part of shelves 8 to be hubbed on the fulcrum 8d, its top is with pin 8a and arbor 7 companies of living, and the pin 8b of its upper end is embedded in the S shape crank slot of rocker 10 right-hand members, and the lower end of its lower end 8c and trip(ping) lever 9 connects; The upper end of trip(ping) lever 9 is hubbed on the bar axle 9b, and its middle part is embedded in the annular groove of castle wheel 12, and lower end 9a and the lower end 8c that draws shelves 8 connect; The middle part of rocker 10 is hubbed on the fulcrum 10b, and right-hand member is established S shape crank slot, and transmission wheel 11 is set on the rocker post 10a of its left end; Fast group third wheel 13 and fast-dialing wheel 14 are located between transmission wheel 11 and the date wheel 2, and fast-dialing wheel 14 is provided with fast shifting block 14b.

The locating device of described date wheel 2 adopts the backstay 6 of pole spring unification, and this backstay 6 is made by a rubber-like reed, and an end of this reed is fixed on the clamping plate, and other end 6a inlay card is in the gear teeth of date wheel 2, to 2 elasticity positioning actions of date wheel.

Its course of work is: when arbor 7 is pulled out one grade to the right, draw the pin 8a on shelves 8 tops to be drawn, making it make clockwise direction around fulcrum 8d rotates, its lower end 8c then promotes the 9a end of trip(ping) lever 9, making its distaff axle 9b make clockwise direction rotates, and castle wheel 12 pushed away left along square tenon 7a move a step, make castle wheel 12 and transmission wheel 11 engagements; Simultaneously, being located at the pin 8b drive rocker 10 that draws shelves 8 upper ends rotates counterclockwise around its fulcrum 10b, make the transmission wheel 11 that is enclosed within on the rocker post 10a along with the rotation displacement of rocker 10 to and fast third wheel 13 position engaged of dialling, this moment castle wheel 12 straight-tooth, transmission wheel 11, dial third wheel 13 soon and fast-dialing wheel 14 all is in engagement; After rotating arbor 7, the square tenon 7a of arbor left end drives castle wheel 12, transmission wheel 11, dials third wheel 13 soon, and fast-dialing wheel 14 rotates, and date wheel 2 has been stirred in the rotation of the fast shifting block 14b on the fast-dialing wheel 14, has reached quickly calibrated purpose.

Adjust when finishing, arbor 7 is pushed away one grade left, draw shelves 8 counterclockwise rotated by masterpiece, its upper end 8b makes rocker 10 do the clockwise direction rotation simultaneously, transmission wheel 11 and fast-dialing wheel 13 drop out of gears finish to exchange work soon work, and trip(ping) lever 9 is under the effect of return spring 16, get back to initial position, castle wheel 12 resets thereupon.
