Abstract
The utility model relates to a calendar mechanism of a wristwatch. Two long holes which have the identical shape, size, and plane coordinate position are respectively arranged on a main splint and a calendar cover plate, and a spacing spring is embedded in the main splint. A date change wheel unit can rotate and move in the long holes to poke the teeth of a calendar ring to change dates, and the utility model can realize normal time traveling date change and needle poking quick date change. The utility model has the advantages of reasonable structural design, convenient operation, reliable work, and high performance in part manufacturing and assembling technology, and the utility model is favorable for enhancing production efficiency and is suitable for being additionally arranged on small and thin type wristwatch movement.
Description
The utility model is a kind of wrist-watch calendar mechanism.
The function of wrist-watch calendar mechanism comprises normally walks Shi Huanri and group fast quick change day of pin.Existing metallic calendar mechanism complex structure is not suitable for being attached on the small-sized watch movement.For example: existing a kind of calendar mechanism is to make a profile hole on the date finger driving wheel 3 that has a long tooth 4 as shown in Figure 1, puts into a U-shaped spring 6 in the hole, rotation by date finger driving wheel 3 and date finger driving wheel 3 with respect to axle 3 ' the plane move, realize above-mentioned functions.This complex structure part processing and assembly process process are poor, and because profile hole must guarantee that the U-shaped spring has enough deformation ranges in the hole, so that date finger driving wheel can not be done is too little, are not suitable for small-sized watch movement.
The purpose of this utility model is in order to provide a kind of simple in structure, and processing and easy to assembly is suitable for being attached to the calendar mechanism on the small-sized slim watch movement.
Wheel component, date finger driving wheel parts, backstay, jumper spring and date rings when this calendar mechanism comprises calendar.Be characterized in that a shape is respectively arranged on bottom plate and calendar cover plate, the identical elongated hole of size and plane coordinates position, be embedded with a spacing spring on the bottom plate.Normally walk constantly and drive the date finger driving wheel parts by date wheel, the side that the date finger driving wheel axle is against in the elongated hole is rotated, and the long tooth of date finger driving wheel is stirred the date rings tooth and realized changing day when normally walking.When dialling pin,, realize dialling fast quick change day of pin by the rotation of date finger driving wheel parts in elongated hole and the effect of mobile and spacing spring.
Fig. 2 is embodiment of the present utility model.
Fig. 3, Fig. 4 are the concrete duty of embodiment.
Among the figure: wheel component, 1 ' hour wheel sheet, 2 date wheels, 3 date finger driving wheel parts, 3 ' date finger driving wheel axle, 3 " sun-changing wheel, the long tooth of 4 date finger driving wheels, 5 date rings, 5 ' date rings tooth, 6 spacing springs, 7 bottom plates, 8 calendar cover plates, 9 backstays, 10 jumper springs during 1 calendar.
The details and the working condition of structure are described in detail in detail below in conjunction with accompanying drawing.
A shape, the identical elongated hole of size and plane coordinates position are respectively arranged on bottom plate 7 and the calendar cover plate 8, also be embedded with a spacing spring 6 on the bottom plate 7.Can rotate and move in the elongated hole of date finger driving wheel parts 3 on bottom plate 7 and calendar cover plate 8.Spacing spring 6 changes under day state when normally walking, be pressed in date finger driving wheel axle 3 ' the right side.Date finger driving wheel axle 3 ' " make an integral body with sun-changing wheel 3.During calendar wheel component 1 by hour wheel sheet 1 ' and tubulose date wheel 2 be pressed into one.Under the state, wheel component 1 clockwise rotates during calendar when normally walking, and date wheel 2 drives date finger driving wheel parts 3 and rotates counterclockwise, date finger driving wheel axle 3 ' the lean against left side of elongated hole.When forwarding to, date finger driving wheel parts 3 change a day position, be the long tooth 4 of date finger driving wheel with date rings tooth 5 ' a face when contacting as shown in Figure 2, the long tooth of date finger driving wheel 4 promotes a tooth pitch of date rings teeth 5 ' turn over, position by the backstay 9 and the jumper spring 10 that are fixed on the calendar cover plate 8, finish one thus and change a day action.When the fast quick change of needs during day, button is transferred to fall to dial pin, wheel component 1 is rotated counterclockwise during calendar, and date wheel 2 drive date finger driving wheel parts 3 turn clockwise.When the long tooth 4 of date finger driving wheel go to date rings tooth 5 ' and the b face when contacting as shown in Figure 3 because the positioning action of backstay 9, jumper spring 10, long tooth 4 be subjected to date rings tooth 5 ' stop.Date finger driving wheel parts 3 move right as shown in Figure 4 along elongated hole when clockwise direction is rotated under date wheel 2 drives, move to the long tooth 4 disengaging date rings teeth 5 of date finger driving wheel ' after, spacing spring 6 bounces back into it original position immediately.And then dial pin clockwise, the long tooth 4 promotion date rings teeth 5 of date finger driving wheel ' turn over a tooth pitch can be realized once fast quick change day.
The utility model reasonable in design operates nimblely, and reliable operation is suitable for being attached on the little slim watch movement, and part processing and assembly technology performance are good, are conducive to enhance productivity.
