Zusammenfassung: | The utility model discloses a hand winding mechanism of a large mechanical watch. The hand winding mechanism comprises a winding shaft and a winding core shaft, wherein the winding shaft is screwed with the winding core shaft; a round shoulder is formed on the winding core shaft, an external thread is formed on one side of the round shoulder, a square tenon is formed on the other side of the round shoulder, and an internal thread hole adapted with the external thread is formed on the square end of the winding shaft. The hand winding mechanism has the following beneficial effects that the winding shaft and the winding core shaft are two independent components, direct winding is performed on the winding shaft, the torque is directly transmitted to a winding box, and the winding tradition ratio is increased by four times, thus the winding process is labor-saving and time-saving, so as to provide guarantee for the promotion and volume production of large manipulators. |
