Description

During clock and watch numerals time-frame flying back type, divide indicating mechanism

Technical field

The utility model relate to a kind of clock and watch " time ", " branch " indicating mechanism constantly, specifically be a kind of digital time-frame flying back type " time ", " branch " indicating mechanism, this mechanism " time " with time the numeral in the window on the time-frame, the time window in operational process, indicate " branch ", finished 1 time and return action in per 1 hour.

Background technology

Now the machinery produced of China and pointer quartz clock and watch " time " and " branchs " all adopt the pointer indication, hour hands and minute hand all are that the center of rotation that centers on self is rotated operation continuously, texture ratio is dullness.About discontinuous operation and when umerical, divide indicating mechanism, up to the present, in Chinese patent literature, find as yet.

Summary of the invention

The utility model technical issues that need to address are, a kind of when brand-new, branch indicating mechanism is provided, this mechanism " time " by numeral; The time window and expression in its window " time " digital synchronous operation, and indication " branch ", the time window finished 1 time in per 1 hour and return action, what promptly arrive " 60 minutes " is returned to " 0 minute " that reference position is indicated next period in a flash, with the digital conversion in the window constantly be next period " time " numeral.Because being provided with time-frame returns, display panel is continuous operation, has eliminated " branch " that cause because of backlash when returning and show the phenomenon of pausing or lagging behind on showing.

During clock and watch of the present utility model numeral time-frame flying back type, divide indicating mechanism, it is characterized in that:

1) its driving-chain is:

Embodiment

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

Embodiment adopts the 1. to organize data.See Fig. 1, its driving-chain is:

Stride tooth axle 2, time-frame third wheel 3, display panel third wheel 6 coaxial interlocks; Time-frame wheel 4 and demonstration plate wheel 7 are coaxial; Show plate wheel 7 and display panel 8 coaxial interlocks; Time-frame wheel 4 and time-frame 9 coaxial interlocks.Hour wheel is 48 teeth, and striding the tooth axle is 12 teeth, and display panel third wheel 6 is 30 teeth, shows plate wheel 24 teeth, and time-frame third wheel 3 has 30 teeth, a breach is arranged every 120 °, and each breach lacks 2 teeth (scarce altogether 6 teeth).Control tooth fan 5 is 11 teeth.Window 12 when being distributed with 1 on the display panel 9.Clockwise direction is evenly equipped with " 1,8,3,10,5,12,7,2,9,4,11,6 " totally 12 digital (see figure 3)s on the display panel 8.

Return spring 11 is fixed on the substrate of movement, its head be fixed on control tooth fan 5 on contacting by following closely 10, its elastic force can force the control tooth to fan 5 clockwise direction and turn to banking pin 13, and counterclockwise moment is returned to reference position to drive time-frame 4 and time-frame 9.

In Fig. 2, clock and watch are striden tooth axle 2 by hour wheel 1 drive and are rotated through the series of gears transmission, and time-frame third wheel 3 and display panel third wheel 6 rotate simultaneously.Time-frame

third wheel

3 and 4 engagements of time-frame wheel, display panel third wheel 6 and 7 engagements of demonstration plate wheel.Per hour hour wheel 1 is changeed 1/12 week (turning over 4 teeth), and stride tooth axle 2, display panel third wheel 6, time-frame third wheel 3 and changeed for 1/3 week simultaneously, time-frame wheel 7 and divide plate wheel 4 per hour to change promptly 150 ° of 5/12 weeks, just 5 " time " scale, see Fig. 3, Fig. 4.Fig. 5 is a hour wheel → stride tooth axle/time-frame third wheel → time-frame wheel/time-frame operational process synoptic diagram, moves 1 hour, has just become on the position of " 8 " " 9 ".

Fig. 6～Fig. 7 is that time-frame/time window of embodiment 1 returns the process synoptic diagram.Fig. 6 is a reference position, and this is " 0 " of window 12 sensing scale divisions constantly, and the numeral in the window is " 8 ", i.e. expression " 8: 0 ".Time-frame third wheel 3 continues counterclockwise to rotate, drive time-frame 4/ time-frame 9 clockwise direction and rotate, the time window 12 indications divide variations constantly, and the time numerals in the window 12 remain unchanged; Control tooth fan 5 simultaneously and also counterclockwise rotate, return spring 11 is lifted.When running to the situation of Fig. 7, because of having breach on the time-frame third wheel 3, it is about to break away from engagement with time-frame wheel 4, and next tooth behind the breach is not taken turns 4 engagements with time-frame as yet, and this moment, return spring 11 was lifted to greatest extent.Take turns 4 in a flash out-of-gear at time-frame third wheel 3 and time-frame, the elastic force of return spring 11 obtains discharging, forcing the control tooth to fan 5 clockwise direction rotates, drive time-frame and take turns the rapidly rotation counterclockwise of 4/ time-frame 9, this in a flash time-frame take turns 4/ time-frame 9 and got back to reference position, the time window 12 point to " 0 "; And display panel 8 this moment lattice when also turning over 5, so the time window 12 inside numeral become " 9 ", i.e. expression " 9: 0 ", time-frame third wheel 3 begins engagement again with time-frame wheel 4, thereby has finished once circulation.
