Abstract

The utility model discloses a reciprocating time interval indicating mechanism of a horologe, which mainly comprises a main wheel, a cam component with a driving gear, a segment gear with an elastic element, a pointer wheel component with a pointer, and a dial, wherein the main wheel can select an hour wheel, a minute wheel or a second wheel according to the length of indicated time intervals. The dial is arranged on a horologe panel for denoting time intervals. The main wheel is engaged with the driving gear in the cam component through a direct mode or through a driving setting wheel component, and drives a lifting cam to rotate. The segment gear clings to the cam under the action of the elastic element, and swings along with the push of the cam. The segment gear is engaged with a pointer wheel in a pointer wheel component through the direct mode or through the pointer setting wheel component, and drives a pointer for indicating time intervals on the time interval dial to swing in a reciprocating mode. Because a novel horologe indication mode is contributed, various indication modes can be formed if the novel horologe indication mode is combined with the existing indication mode. The utility model creates conditions for developing novel horologe products.

Description

The reciprocating period indicating mechanism of clock and watch

Institute's technical field

The utility model relates to timer, specifically refers to a kind of period indicating mechanism of clock and watch.

Background technology

Timer generally all adopt the rotation of pointer or rotating disk indicate second, branch, the time, the period such as day, week, the moon.In the prior art, these pointers or rotating disk are general only along clockwise direction rotation.In the style design of timer, it is dull that indicating mode just seems, lacks variation like this.

Summary of the invention

The purpose of this utility model is to propose a kind of reciprocating period indicating mechanism of clock and watch, when working, the pointer of this indicating mechanism indicates the period to a direction (generally being clockwise direction) rotation, reverse immediately to this period end cycle (generally being counterclockwise) fast return starting point, restarting the indication operation in next cycle period then, is a kind of brand-new period indicating mechanism of timer such as clock and watch.

The reciprocating period indicating mechanism of a kind of clock and watch of the present utility model, mainly comprise a main wheel, this main wheel can be selected hour wheel, minute wheel or second wheel according to the length of indicated period, the cam pack that also has a belt driving gear, one has the sector gear of flexible member, the pointer wheel assembly and one of one band pointer is located at the scale of the expression period on the clock and watch panel; Between main wheel and cam pack, can be provided with transmission in case of necessity and cross wheel assembly, between sector gear and pointer wheel assembly, can be provided with in case of necessity and indicate wheel assembly; Wherein main wheel transmission gear direct or that cross in wheel assembly and the cam pack by described transmission meshes, and drives the lifter cam rotation; Sector gear is close to described cam under the effect of flexible member, and is promoted to swing by this cam; Described sector gear pointer wheel direct or that cross in wheel assembly and the pointer wheel assembly by described pointer meshes, and drives the pointer reciprocating swing of doing the period indication on described period scale.

During work, main wheel directly or by transmission is crossed the rotation of wheel assembly drive lifter cam, and promotes sector gear slowly to a direction swing; Sector gear carries out the period indication directly or by indicating wheel assembly that pointer is swung along clockwise direction then; Behind a period indication end cycle, cam is got back to lowest order fast through a steep backhaul curve, drive sector gear backswing rapidly simultaneously, pointer wheel is reversed rapidly, pointer returns the pendulum initial position that flies back rapidly, restarts the indication of a new time cycle.Formed pointer like this and be rotated in the forward the brand-new indicating mode that carries out period indication, reverse fast return initial position, given the consumer sensation with a kind of novelty.

The effect that the utility model is useful is: contributed a kind of clock and watch indicating mode of novelty, combined with existing indication form, can form omnifarious indicating mode, for exploitation fangle clock and watch product has been created condition.

Description of drawings

Fig. 1 is the drive mechanism synoptic diagram of an embodiment of the present utility model;

Fig. 2～Fig. 6 is that the various reciprocating pointers of wrist-watch panel are arranged synoptic diagram; Wherein Fig. 2 is located at reciprocating calendar directly over the panel for pointer; Fig. 3 is located at reciprocating minute hand directly over the panel for pointer; Fig. 4 is located at the reciprocating calendar of panel top one side for pointer; Fig. 5 is located at the reciprocating hour hands and the minute hand of panel central authorities both sides for pointer; Fig. 6 is located at the reciprocating calendar and the Zhou Li of both sides, panel top for pointer.

Among the figure: 1 hour wheel, 2 24 little hour wheels, 3 calendar shifting blocks, 4 date wheels, 5 lifter cams, 6 sector gears, 7 spring bases, 8 calendars were indicated the tooth axle, 9 calendars indication setting pinion, 10 indicator wheels, 11 pointers, 12 calendar scales, 13 seconds scales, 14 week scale, 15 hours scales, 16 index plates.

Embodiment

The utility model is described in further detail now to reach accompanying drawing in conjunction with the embodiments.

Is example with a pointer center in the reciprocating calendar indicating mechanism of centre of surface, its structural representation such as Fig. 1, the synoptic diagram of its panel such as Fig. 2.Among Fig. 1, main wheel adopts the hour wheel 1 that is positioned on the table central shaft, hour wheel is crossed

wheel assembly

2,3 and cam pack 4,5 engagements by transmission, the described wheel assembly of crossing is formed by one 24 hours wheel 2 and one calendar shifting block 3 riveteds, under the drive of hour wheel 1, wheel 2 rotated a circle with calendar shifting block 3 in per 24 hours in 24 hours, simultaneously date wheel 4 one teeth stirred in the cam pack of calendar shifting block 3; Cam pack is by a date wheel 4 and an involute urve lifter cam sheet 5 consolidations with 31 teeth, and date wheel 4 rotates a circle with cam 5 per 31 days (being January) like this; Because the effect of flexible member spring base 7, the push rod position of sector gear 6 abuts against on the curve of cam 5, and under the promotion of cam 5, sector gear 6 also turns over a tooth every day; Sector gear 6 makes the pointer wheel 10 and the angle of pointer rotation 11 every days equal lattice of the calendar scale 12 on the panel by indicating

wheel assembly

8,9 and being enclosed within 10 engagements of the pointer wheel in the

pointer wheel assembly

10,11 on the central shaft, promptly is equivalent to 1.After passing by 31 days, the curve of cam 5 is got back to lowest order from most significant digit fast through a steep backhaul curve, drive simultaneously sector gear 6 rapidly backswing in the other direction, pointer wheel 10 reverse rapidly, pointer returned from 31 days to fly back rapidly puts position on the 1st, has finished the calendar in January and has indicated.

Describedly indicated wheel assembly to press to be located at a calendar and to indicate on the tooth axle 8 and combine by calendar indication setting pinion 9.

Because the layout of drive mechanism is more flexible, described pointer center can overlap with the center of clock and watch, also can be according to the needs of style, pointer and indication scale are arranged on flexibly other position of clock and watch panel, its indication period can be calendar, week, monthly calendar, also can be second, branch, the time etc. the various periods, shown in Fig. 2～6.
