Abstract

The utility model relates to a pointer formula date indication clock and watch that flies back, the technical problem that it needs to solve is, and the pointer can return in the twinkling of an eye during date conversion, and provides new space for the innovative design of clock dial face. The utility model discloses a driving chain does: the calendar wheel comprises an hour wheel (1) - → a day poking wheel (2)/a calendar poking head (3) - → a calendar wheel (5)/a calendar wheel shaft sleeve (6)/a calendar pointer (14). When the calendar shifting head (3) shifts the teeth of the calendar gear and the calendar wheel nail (9) pushes the calendar positioning rod (10) to lift, the pointer can be driven by the calendar wheel coil spring (7) to reversely fly back, the date conversion is completed instantly, and the pointer is limited by the cover plate groove 15-1 and is stabilized at the initial position.

Description

Pointer flying back type date indication clock

Technical field

The utility model relates to a kind of with the pointer clock and watch on indication date, specifically be pointer flying back type date indication clock, and this pointer can turn back to 1 in a flash when closing to an end in 31st.

Background technology

The clock and watch that have the date pointer in the prior art, the date is to represent that with the date numeral of circumferential arrangement on the pointer indication card operation of pointer is rotated continuously along circumference.Its deficiency, the one, the date conversion lacks dynamic, and the 2nd, the general layout of the circumferential arrangement of date numeral has seriously fettered the innovative design of card.

Summary of the invention

The technical problems to be solved in the utility model is, pointer can return moment during the date conversion, is full of innervation, and provides new space for the innovative design of clock and watch card.

Pointer flying back type of the present utility model date indication clock is characterized in that:

1) its driving-chain is: hour wheel-→ group sun/calendar shifting block-→ date wheel/date wheel axle sleeve/calendar indicator;

2) dial to be fixed with on the sun and dial a day catch nail;

3) be fixed with on the date wheel and return banking pin and date wheel nail, the inner of date wheel disc spring is fixed on date wheel shaft and puts, and its outer end is fixed on the movement;

4) movement is provided with the date indicator jumper that back stop cooperates and stirred by the date wheel nail, is provided with the push rod that back stop cooperates and stirred by calendar shifting block retaining nail;

5) on the cover plate between dial plate and movement a fan groove is arranged, be installed with the date wheel nail in the groove and return banking pin.

The utility model is identical with traditional calendar ring type calendar clock, except that the end of month in the solar month need not manual setting, must adjust the date by dialling pin or general rapid adjustment mechanism separately when February and other solar month of 30 days.

The date of this patent is to represent with the numeral of pointed, and the calendar letter disk that is distributed with the date numeral on imperfect circumference is fan-shaped, needs time on conversion date index futures pin to turn over an angle; And can be at 1 day that turns back in a flash time month when running to this pointer when closing to an end in 31st voluntarily.

The utility model provides a kind of brand-new date display mode, and is more intuitively more eye-catching than common digital display mode, and innervation is arranged during the date conversion.And because the date display window is fan-shaped, occupation space is less in the plane, thereby is convenient to the multi-functional design of product.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.

Embodiment 1, sees Fig. 1～Figure 10.Fig. 1 is the schematic appearance of embodiment 1.The numeral (or mark) that calendar indicator 14 points in the date indicating window 16 is represented the date.This example includes group sun 2, calendar shifting block 3, group day catch nail 4, date wheel 5, date wheel axle sleeve 6, date wheel disc spring 7, calendar indicator 14, returns banking pin 8, date wheel nail 9, date indicator jumper 10, push rod 11, cover plate 15 (see figure 3)s etc.

The described group of sun 2 rotates with calendar shifting block 3 coaxial interlocks; Date wheel 5, date wheel axle sleeve 6, the coaxial interlock of calendar indicator 14 threes; Calendar shifting block retaining nail 4 is fixed on to be dialled on the sun 2; Returning banking pin 8 and date wheel nail 9 is fixed on the date wheel; The inner of date wheel disc spring 7 is fixed on the date wheel axle sleeve 6, and its outer end is fixed on the matrix of movement motionless.The date indicator jumper 10 that movement is provided with back stop 13 cooperations cooperates with date wheel nail 9, establishes the push rod 11 that is combined with back stop 12 and cooperates with calendar shifting block retaining nail 4; One fan groove 15-1 is arranged on the cover plate 15 between dial plate and movement, be installed with date wheel nail 9 in the groove and return banking pin 8.Its structural arrangement is seen Fig. 4.

Clock and watch drive 1 per 12 hours one weeks of rotation of hour wheel through a series of transmissions, and hour wheel 1 drives again dials the sun 2 rotation (see figure 2)s.The gear ratio of dialling the sun and hour wheel is 2: 1, it is 44 teeth that this example is dialled the sun 2, hour wheel 1 is 22 teeth, so dial the sun 2 circled in per 24 hours, stirred 5 one teeth of date wheel in per 24 hours with the calendar shifting block 3 of dialling the sun 2 interlocks, turn over an angle with the date

wheel axle sleeve

6 and 14 while of the calendar indicator clockwise direction of date wheel 5 interlocks, date wheel disc spring 7 is also by angle of rolling-in.In Fig. 5, calendar indicator points to 1, and calendar shifting block 3 is about to stir the calendar gear teeth at this moment.Calendar shifting block 3 is rotated further, and dials 5 one teeth of date wheel, and calendar indicator 14 points to 2.Return banking pin 8 and date wheel nail 9 also simultaneously clockwise direction turn over an angle (see figure 6).

In Fig. 7, moved to 31, this moment, date wheel was followed closely 9 positions that arrived near date indicator jumper 10, and date wheel disc spring 7 is screwed.In Fig. 8, clock and watch continue operation, and calendar shifting block 3 is stirred the calendar gear teeth, date wheel nail 9 promotes date indicator jumper 10 and lifts in the direction of arrows, and push rod 11 is because the effect of push rod back stop 12 is rotated push rod 11 in the direction of arrows, date wheel disc spring 7 is torqued-up to greatest extent, returns to be about to begin.When the head of calendar shifting block 3 breaks away from (positioning head of date indicator jumper 10 also leaves the calendar gear teeth simultaneously) in an instant of the calendar gear teeth, the elastic force of the date wheel disc spring 7 that is screwed obtains discharging and makes date wheel 5 (counterclockwise) rapidly reversing in the other direction.Fig. 9 represents that date wheel 5 and calendar indicator 14 are in the situation that returns in the way.When returning banking pin 8 when arriving cover plate grooves 15 terminal, return action and finish, calendar indicator points to 1, and push rod 11 afterbodys enter the breach (see figure 10) of date indicator jumper 10.After clock and watch continue operation, before calendar shifting block 3 and date wheel toe joint touch, calendar shifting block retaining nail 4 promotes the head of push rod 11 earlier, make its afterbody also enter the position location in the direction of arrows by direction of arrow perk, the date indicator jumper 10 of Fig. 5, calendar back stop 13 is pushed down date indicator jumper 10 to guarantee positioning stablity, promptly arrive the situation of Fig. 5, thereby finished once circulation.
