Document Type and Number:
WIPO Patent Application WO/2014/127706
Kind Code:
A1
Abstract:
Disclosed is a quartz watch movement which does not require a clutch lever and is capable of improving the travel time reliability of a movement. A minute wheel (2) of the quartz watch movement is connected to a handsetting wheel (6) by an intermediate wheel (5) in a transmission mode, a lower shaft tenon of a shaft of a third wheel (4) penetrates through a space which omits an original clutch lever (8) and is placed in a corresponding shaft hole in a main plate (92), elastic connection structures capable of relatively rotating by which a third-wheel shaft gear (41) and a minute wheel piece gear (22) which are engaged together and are in a static state are arranged between a minute wheel tube (23) and the minute wheel piece gear (22) when a winding stem (7) is externally pulled or the minute hand is adjusted through the handsetting wheel (6), the intermediate wheel (5) and a minute wheel shaft gear (21), a second-hand stop lever (83) which can be connected to or disconnected from a second-hand stop electrode (82) is arranged in front of the winding stem (7), a component omitting the clutch lever is used to guarantee that a clock is in an accurate engagement state among the second wheel (1), the third wheel(4) and the minute wheel (2) and improves the travel time reliability of the movement. Meanwhile, the elastic connection structures capable of relatively rotating are arranged between the minute wheel tube (23) and the minute wheel piece gear (22), so that it is still guaranteed that the quartz watch is accurate in travel time and has the function of efficiently adjusting the hour hand and the minute hand in the case of omitting a handsetting middle wheel (61).
