Embodiment

Below, with embodiment, the present invention is described in further details by reference to the accompanying drawings:

As shown in Figures 1 to 7, the trip gear that automatically winds up of wrist-watch of the present invention is arranged on watchcase, comprises, watchcase parts 1, arbor assembly 4 and button parts 11; Described arbor assembly 4 connects as one through watchcase parts 1 and button parts 11.Described watchcase parts 1 comprise watchcase 2 that pressing is integrated and pipe 3, pipe 3 are formed with external thread; Described arbor assembly 4, comprise arbor 5, arbor side's core 6, arbor extending shaft 7, arbor sleeve pipe 8, first pin 9 and the second pin 10, arbor 5 and arbor side's core 6 pressing are integrated, and fixed by the first pin 9, arbor extending shaft 7 and arbor sleeve pipe 8 pressing are integrated, and fixed by the second pin 10, arbor sleeve pipe 8 and arbor side's core 6 are engaged by square tenon or depart from; Because arbor extending shaft 7 and the fit system of arbor sleeve pipe 8 are pressings, so when pulling arbor extending shaft 7, arbor sleeve pipe 8 will slide on arbor side's core 6, and when arbor sleeve pipe does not have and arbor side's core 6 coordinates, arbor Fang Xin and arbor sleeve pipe are can be in relative rotation.Described button parts 11 comprise button 12, button core 13 and O-ring seal 14, button 12 and button core 13 pressing are integrated, and O-ring seal 14 is pressed in inside, described button core 13 is formed with internal thread, pipe 3 and button core 13 are threaded connection and are integrated, button 12 is tightened on arbor extending shaft 7, and button parts 11 are integrated with arbor assembly 4 one-tenth.

The duty of a kind of wristwatch automatic winding trip gear of the present invention when normally wearing: as Fig. 1, 5, 6, shown in 7, the external thread of pipe 3 is tightened in the internal thread of the button core 13 in button parts 11 and watchcase parts 1, pipe 3 is tightly pushed down the O-ring seal 14 in button parts 11, movement is made to keep sealing state, now button parts 11, arbor extending shaft 7 and arbor sleeve pipe 8 are that relative watchcase parts 1 are fixed, and arbor sleeve pipe 8 and the square tenon of arbor side's core 6 are disengaged condition, when movement winds up automatically, arbor 5 and arbor side's core 6 just can not rotate freely by the impact of watchcase parts 1 like this, so only need when automatic system is winded up to overcome the force of sliding friction between arbor and vertical wheel castle wheel, and the strength that this sliding friction force rate vertical wheel and castle wheel throw off the set spring that will overcome is much smaller.

The duty of a kind of wristwatch automatic winding trip gear of the present invention when pulling needle: as shown in FIG. 4,5,6, 7, the basis that movement winds up continues to pull negative winding stem part 11, because the 6a place in now arbor side's core 6 can be close to the 8a in arbor sleeve pipe 8 (as shown in Figure 7).So pull arbor sleeve pipe 8 can continue to drive arbor side's core 6 and arbor 5, and make arbor 5 be in pulling needle gear, because arbor side's core 6 and arbor sleeve pipe 8 are still engaged by square tenon, so rotating handle head member 11 will drive arbor 5 to rotate, pulling needle function can be realized.

To reset after completing bar or pulling needle action.Pushing handle head member 11, thus drive arbor extending shaft 7 and arbor sleeve pipe 8 on arbor side's core 6 to doing movement, in moving process, arbor side's core 6 becomes disengaging with the square tenon of arbor sleeve pipe 8 again from engaging, when the button core 13 in button parts 11 encounter in watchcase parts 1 pipe 3 time, screw button parts 11, in screwing operations, arbor extending shaft 7 can withstand arbor side's core 6 and then promote arbor 5, arbor 5 is made to get back to from pulling needle gear the gear that winds up, pipe 3 is tightly pushed down the O-ring seal 14 in button parts 11 simultaneously, ensure movement sealing.

The duty of wristwatch automatic winding trip gear of the present invention when manually winding up: as shown in Fig. 3,5,6,7, unscrew button parts 11, make the button 12 in button parts 11 and pipe 3 is departed from watchcase parts 1, button parts 11 drive arbor extending shaft 7 to screw out together with arbor sleeve pipe 8 in the process, and arbor sleeve pipe 8 enters into the position of engagement with the square tenon structure of arbor side's core 6 by disengaged position.Now rotating handle head member 11 will drive arbor 5 rotate by square tenon, thus winds up for movement.

The present invention is because trip gear design is on table Sales, and realized by arbor and table hat structure, efficiently solve movement insufficient space and the defect of detaching structure cannot be assembled, when particularly movement winds up automatically, arbor can freely rotate, and little a lot of just can the realization of strength that the resistance ratios overcome overcomes set spring departs from; It is worthy of note that the present invention is not only applicable to slim or small-sized automatic movement, be also adapted in timepiece movement, increasing the trip gear that the automatic watch movement of releasing mechanism uses simultaneously.
