The part of described position-limited wheel 22 hypodontias lacks 2 teeth.
Fig. 7 shows the wrist-watch center that the utlity model has fast shifting function and returns the center that the pointer calendar mechanism is installed in movement.But what be worth to propose is, the wrist-watch center that the utlity model has fast shifting function returns the pointer calendar mechanism also can move on to other positions from the center of movement with return wheel component 25, so just can be combined into more wrist-watch pattern.
In addition, by changing the ratio of gear of gear, the wrist-watch center that the utlity model has fast shifting function returns the indication that returns that the pointer calendar mechanism can also be used for minute hand, hour hands, Zhou Li and monthly calendar.
The course of work that the wrist-watch center that the utlity model has fast shifting function is returned the pointer calendar mechanism is illustrated below:
As shown in Figure 1, wrist-watch is when normally walking under the state, the time wheel component 3 drive reverse wheels 7 rotations, reverse wheel 7 drives 11 rotations of turning wheel parts, turning wheel parts 11 are stirred position-limited wheel parts 21 and are rotated, position-limited wheel parts 21 drive return wheel component 25 and rotate, and return wheel component 25 is given sector gear parts 36 with transmission of power at last, and sector gear 38 is rotated in the counterclockwise direction.
As shown in Figure 2, when wrist-watch runs to when being about to change day, described turning wheel parts 11 enter into duty, along with the operation of wrist-watch, stir the gear teeth that nail 17 is just stirred lower limit wheel 23, allow it rotate gear teeth; Meanwhile, drive return wheel component 25 and rotate an angle, thereby drive angle of calendar indicator 46 rotations, point to the day mark of next day on the fan-shaped subtabulation dish (not shown).
As shown in Figure 3, when needs are stirred calendar indicator 46 fast, can push the plane of fast driving lever 19 1 side projections, the tip of its opposite side just promotes 23 rotations of lower limit wheel, position-limited wheel 23 drives return wheel component 25 and rotates, thereby drive calendar indicator 46 and rotate to the precalculated position rapidly, reach the fast purpose of dialling; Fast dialling finishes, and described fast driving lever spring 27 disengages itself and position-limited wheel 23 for fast driving lever 19 provides restoring force, state when wrist-watch continues to keep normally walking.
As shown in Figure 4, when described sector gear parts 36 rotated to extreme position, return wheel 43 just in time was meshed with last tooth before the part of position-limited wheel 22 hypodontias; Simultaneously, stir nail 17 and entered the working position.Then, as shown in Figure 5, the described nail 17 of stirring toggles it to position-limited wheel parts 21 position that position-limited wheel 22 hypodontias part is aimed at return wheel component 25, at this moment return wheel component 25 breaks away from engagement with position-limited wheel parts 21, because down return wheel 44 is meshed with sector gear 38, under the restoring force effect of sector gear spring 39, return wheel component 25 drives calendar indicator 46 rapid reverse rotations.When sector gear parts 36 are got back to zero-bit, blocked by eccentric nail 34, simultaneously, return wheel component 25 drives calendar indicator 46 and gets back to zero-bit, finishes returning indication.
The fast shifting function that the wrist-watch center that the utlity model has fast shifting function is returned the pointer calendar mechanism is described in detail below:
Under state as shown in Figure 1, stir nail 17 not in the turning circle of lower limit wheel 23, press fast driving lever 19, the tip of fast driving lever 19 opposite sides just promotes lower limit wheel 23 and rotates gear teeth, thereby drives calendar indicator 46 rotations one lattice.
Under state as shown in Figure 2, stir in the turning circle that nail 17 entered lower limit wheel 23, press fast driving lever 19 and promote 23 rotations of lower limit wheel, the gear teeth of lower limit wheel 23 promote to stir nail 17 and clockwise rotate up to the turning circle that withdraws from lower limit wheel 23, the tip of fast driving lever 19 opposite sides just promotes lower limit wheel 23 and rotates gear teeth, the lattice thereby calendar indicator 46 is beated.
As can be seen, the wrist-watch center that the utlity model has fast shifting function returns the pointer calendar mechanism and does not have the fast forbidden zone of dialling; When normally walking, wrist-watch under the state, in any moment, all can realize its fast shifting function.
