Abstract

The utility model relates to a movement of a quartz alarming clock with a calendar, composed of a quartz oscillator and a clock gear, wherein, the circumferential outboard of the hour hand gear is also provided with a set of calendar dials with inner gears, a day-setting wheel with double-gear as well as a day setting wheel with cams. Meanwhile, a set of quick setting devices, each of which is composed of a quick setting cam with convex teeth and a quick setting day rod gear meshed with the quick setting cam with convex teeth, are arranged at the inner side of the other side of each calendar dial. The adoption of the devices of the utility model can meet people's needs, and the date can be seen from the clock dial of the quartz clock with a calendar; besides, the calendar variation can be hand set with simple structure.

Description

The quartz alarm clock movement of band calendar

A kind of quartz alarm clock movement with calendar relates to the improvement of quartz alarm clock movement.

The calendar structure complexity that on old-fashioned quartz alarm clock movement, is equipped with, the adjustment trouble, and cannot fast tuning.

The purpose of this utility model, being provides a kind of structure with calendar-disc on the basis on the existing quartz alarm clock movement, also be equipped with fast tuning structure simple in structure in this structure, to adapt to people's demand.

The utility model is to implement like this: on quartz alarm clock movement basis, the garden week outside at hour hand gear 6, be equipped with a cover band annular wheel calendar-disc 2, with dual gear dial day back gear 5 and have a cam dial the sun 3, wherein, dialling the gear wheel of day back gear 5 and the gear ratio of the pinion wheel on it is 2: 1, the gearing mesh of gear wheel and clock gear 6, pinion wheel and the outer rotor engagement of dialling the sun 3, the cam of dialling the sun 3 then with the internal tooth engagement of calendar-disc 2.

Below in conjunction with accompanying drawing in detail structure of the present utility model and use are described in detail:

Fig. 1 is the floor map of the quartz alarm clock movement of band calendar;

Fig. 2 is the assembling stretch-out view of Fig. 1;

Shown in Figure 2 as Fig. 1, the quartz alarm clock movement of the said band calendar of the utility model is in order to increase the calendar form, in the circle outside, the garden of hour hand gear 6, be equipped with a cover band annular wheel calendar-disc 2, with dual gear dial day back gear 5 and have a cam dial the sun 3.Wherein, as shown in the figure, dial the gear wheel of day back gear 5 and on it gear ratio of pinion wheel be 2: 1, the engagement of the outer rotor of gear wheel and hour hand gear 6, pinion wheel and the outer rotor engagement of dialling the sun 3, the cam of dialling the sun 3 then with the annular wheel engagement of calendar-disc 2, for fixing calendar-disc 2, then by pressing plate 4 as radial location, and make a spring at pressing plate 4 and push down calendar-disc 2 internal tooths by spring, perform circumferential registration.The edge of calendar-disc 2 is being pressed at the edge of pressing plate 4, as axial location.

General calendar clock when wanting the conversion calendar, all is to adjust calendar by stirring the hour hand gear drive group sun, and adjustment is time-consuming, also easily hinders gear.

The utility model quick pulling mechanism as shown in Figure 1 and Figure 2, dialling day calendar-disc 2 inboards of wheels opposite side, being equipped with a cover again forms by the fast advance cam 7 of band double wedge with the fast date corrector operating lever gear 8 of its engagement, wherein fast advance cam 7 has two double wedges, have only when fast date corrector operating lever gear 8 it is forwarded to when touching mutually with calendar-disc 2, could mesh with the internal tooth of calendar-disc 2, play the effect of dialling day fast.

Because in actual applications, calculated with 24 hours in one day, but on general hour wheel, a circle only is defined as 12 hours, therefore, in order to make calendar-disc 2 per 24 hours rotation one lattice, just needing changes two circles with hour hand gear 6, dial the sun 3 and just turn around, calendar-disc 2 is just changeed a tooth, promptly changes one.Therefore, the best number of teeth of gear wheel of dialling day back gear 5 is 20 teeth, and the best number of teeth of pinion wheel is 10 teeth.

The utility model is to use like this: when hour hand gear 6 rotates, drive hour hands and turn round on clock face.Owing to dial gear wheel and its engagement of day back gear 5, therefore when hour hand gear 6 rotates clockwise, dial day back gear 5 with regard to counter rotation, and the pinion wheel of dialling on day back gear 5 meshes with group sun 3, drive and dial the rotation of the sun 3 clockwise direction, the cam clinching on group sun 3 is on the annular wheel of calendar-disc 2.Therefore, when hour hand gear 6 after 2 weeks of rotation, calendar-disc 2 just can turn over a tooth in a clockwise direction, like this, from the shown date of the date window of clock face then be per 24 hourly variations 1 time.

When needs adjustment calendar, only need counterclockwise rotate fast date corrector operating lever gear 8, because fast date corrector operating lever gear 8 is with the outer rotor engagement of fast advance cam 7, when whenever rotating a circle, just the double wedge with fast advance cam 7 pushes away mutually with the internal tooth of calendar-disc 2, make calendar-disc 2 lattice of walking about clockwise of taking advantage of a situation, just make demonstration on the date window along walking one.

Adopted the said structure of the utility model, what can reach people need see the residing date on the quartz clock with calendar face, and the change of adjustment calendar simply again, brings convenience to the user at features simple structure.

Claims

1, a kind of quartz alarm clock movement with calendar, it is characterized in that the periphery at hour hand gear (6) also is equipped with the calendar-disc (2) of a cover band annular wheel, dialling day back gear (5) and having group sun (3) of cam with dual gear, wherein, dialling day gear wheel of back gear (5) and the gear ratio of pinion wheel is 2: 1, dial day gear wheel of back gear (5) and the gearing mesh of hour hand gear (6), and pinion wheel and group sun (3) engagement.Cam when dialling the sun (3) rotary head on it then with the internal tooth engagement of calendar-disc (2).Dial the sun (3) and whenever circle, calendar-disc turns over a tooth, reflects on the clock face that calendar changed one.

2, according to the quartz alarm clock movement of the said band calendar of claim 1, it is characterized in that can be in the opposite side inboard of said calendar-disc (2), be equipped with a cover again by the fast advance cam (7) of strap cam and the fast dialing device of forming with the fast date corrector operating lever gear (8) of its engagement, wherein the double wedge of fast advance cam (7) has only when fast date corrector operating lever gear (8) forwards it with calendar-disc (2) to and could mesh with the internal tooth of calendar-disc (2) when touching mutually.

3, according to the quartz alarm clock movement of the said band calendar of claim 1, the best number of teeth that it is characterized in that the gear wheel of said group of day back gear (5) is 20 teeth, and the best number of teeth of pinion wheel is 10 teeth.
