Description
Technical field
The utility model relate to a kind of clock and watch " time ", " branch " indicating mechanism, specifically be a kind of numeral " time " indication instantaneously changing formula and " branchs " indicate flying back type mechanism.This mechanism " time " window when being shown in the numeral on the time-frame, its conversion is finished in a flash; " branch " finished 1 time and returned action with the minute hand indication in per 1 hour.
Background technology
Now the machinery produced of China and pointer quartz clock and watch " time " and " branchs " generally all adopt the pointer indication, hour hands and minute hand are that the center of rotation that centers on self is rotated operation continuously, texture ratio is dullness.About the branch indicating mechanism of discontinuous operation, up to the present, in Chinese patent literature, do not find as yet.About show with numeral " time " mechanical mechanism be disclosed in the Chinese patent 03228705.4 " during clock and watch numeral time-frame flying back type, branch indicating mechanism ".This indicating mechanism is because the time-frame area is bigger, and inertia is big, and contact point is also many, and the fault chance that friction causes is also many relatively.
Summary of the invention
The utility model technical issues that need to address are, a kind of novel structure is provided, " branch " " time " wink is moving, the more succinct clock and watch reliably of structure " time " indication instantaneously changing formula and minute hand indicate flying back type mechanism.
Clock and watch of the present utility model " time " indication instantaneously changing formula and minute hand indication flying back type mechanism, it is characterized in that:
1) its driving-chain is:
————

The time plate wheel/hour indicator reset and break spring
|
Hour wheel → the stride tooth axle/third wheel → reseting wheel that resets/the return minute hand ← tooth that resets fan;
Wherein stride the tooth axle and the coaxial interlock of third wheel that resets; The time plate wheel and the coaxial interlock of hour indicator; Reseting wheel and return branch coaxial needle interlock; Reseting wheel and the time plate wheel coaxial;
2) be evenly equipped with " 1~12 " totally 12 numerals on the hour indicator; The third wheel that resets is the gear that agomphosis is arranged;
The agomphosis of the described third wheel that resets is meant the agomphosis of uniform position; At reseting wheel with return after the minute hand angle determines, the agomphosis number can be determined than relation by the tooth of reset third wheel and reseting wheel.
3) reseting wheel and return the per hour clockwise direction angle of rotating of minute hand can select one: 5/12 week (150 °) as required in following data, 7/12 week (210 °), and 11/12 week (330 °),
5/24 week (75 °), 7/24 week (105 °), 11/24 week (165 °),
13/24 week (195 °), 17/24 week (255 °), 19/24 week (285 °),
23/24 week (345 °);
4) reset and break spring and be fixed on the substrate of movement, resetting on its limiting section compressing control tooth fan broken spring by nail, its head with the time plate wheel take tooth and cooperate, its afterbody with the time plate wheel locate and cooperate.
The utility model is reasonable in design, and novel structure is succinct, be a kind of brand-new be full of dynamic clock and watch numeral instantaneously changing formula " time " indicating mechanism and flying back type minute hand indicating mechanism.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2, the driving-chain of this routine mechanism is:

The time plate wheel 8/ hour indicator 9 reset and break spring 7
|
Wherein stride the tooth axle 2 third wheel 3 coaxial interlocks that reset; The time plate wheel 8 and hour indicator 9 coaxial interlocks; Reseting wheel 4 with return minute hand 10 coaxial interlocks; Reseting wheel 4 with the time plate wheel 8 coaxial.The third wheel 3 that resets is that 30 teeth are uniform every 120 ° of gears that lack 2 teeth (scarce altogether 6 teeth).Reseting wheel 4 and return minute hand 10 per hour the clockwise direction angle of rotating be 150 °, be evenly equipped with on the hour indicator 9 " 1,2,3,4,5,6,7,8,9,10,11,12 " totally 12 expressions " time " digital (see figure 5).Hour wheel is that 48 teeth are uniform, and striding the tooth axle is that 12 teeth are uniform, and position of wheel 24 teeth that reset are uniform, and control tooth fan 5 is 11 teeth.Window 11 is for the moment arranged on the dial plate of wrist-watch, and this routine time window is positioned at " 12 " word bit of Watch dail plate.
In Fig. 3, clock and watch are striden tooth axle 2 by hour wheel 1 drive and are rotated through the series of gears transmission, and the third wheel 3 that resets rotates simultaneously.Third wheel 3 and reseting wheel 4 engagements reset.Per hour hour wheel 1 is changeed 1/12 week (turning over 4 teeth), strides tooth axle 2 and changes for 1/3 week simultaneously with the third wheel 3 that resets, and reseting wheel 4 per hour changes promptly 150 ° of 10/24 weeks, and promptly the scale division of " 0~60 " among the figure also is the stroke that minute hand returns.
Fig. 3~Fig. 4 is that the minute hand of embodiment 1 returns and hour digital instantaneously changing process synoptic diagram.Fig. 3 is a reference position, and this moment, minute hand pointed to " 0 " of scale division, the time numerals in the window 11 be " 8 ", promptly represent " 8: 0 ".Third wheel 3 continuation that reset are counterclockwise rotated, and drive reseting wheel 4 clockwise direction and rotate, and return also clockwise direction rotation of minute hand, and indication divides variation constantly; The time plate wheel 8 not with other gearing mesh, so the time plate wheel motionless, and the time numerals in the window 12 remain unchanged; Control tooth simultaneously and fan 5 also rotations counterclockwise, the spring of beating on it is oppressed limiting section 7-1 by nail 6, forcing dozen spring 7 that resets up to move, and its head 7-2 is compressed and slides on the flank of tooth of reseting wheel.When running to the situation of Fig. 4, because of having breach on the third wheel 3 that resets, it is about to and reseting wheel 4 breaks away from engagement, and next tooth behind the breach as yet not with reseting wheel 4 engagements, reset this moment and break spring 7 oneself is compressed to greatest extent.In a flash out-of-gear at the third wheel 3 that resets with reseting wheel 4, the elastic force of breaking spring 7 that resets obtains discharging, and forces the control tooth to fan 5 clockwise direction and rotates, and drives reseting wheel 4 and return minute hand 7 counterclockwise rapidly to rotate, reseting wheel 4 is also being got back to reference position together in a flash, and minute hand points to " 0 ".When dozen spring 7 that resets is compressed to greatest extent, the crown of plate wheel when its head 7-2 has slipped over, the elastic force of breaking spring 7 is discharged, minute hand is finished and returned the in a flash same of action resetting, reset and play spring 7-1 produces moment downwards to the hour indicator gear teeth impact, plate wheel counterclockwise turns over a tooth when forcing, hour indicator also turns over a tooth pitch simultaneously, the time " 8 " in the window 11 be transformed to " 9 ", i.e. expression " 9: 0 ", the third wheel 3 that resets begins engagement again with reseting wheel 4, thereby has finished once circulation.
Embodiment 2.In this example, reseting wheel 4/ return minute hand 10 per hour the clockwise direction angle of rotating be 7/12 week (210 °), the time window 11 the position at " 9 " of Watch dail plate word bit.The ratio of gear of gear and hour indicator, the parts such as breaking spring that resets need be done corresponding adjustment, and its structural principle and driving-chain and embodiment 1 are identical.Fig. 6 is this routine schematic appearance.
