Quartz watch movement

Abstract

The invention discloses a quartz watch clock mechanism provided with no clutch lever and capable of improving the travel time reliability of the clock mechanism. A minute wheel is connected with a needle shifting wheel in a transmission way through a back gear, a lower pivot of a third wheel shaft passes through a space in which an original clutch lever is canceled to be arranged in a corresponding shaft hole on a main clamping plate, a connection structure which enables the third wheel shaft to be always engaged with the minute wheel blade and to rotate elastically relatively at a static state when a handle shaft is pulled outwards and a minute hand is adjusted through the needle shifting wheel, the back gear and the minute wheel shaft is also arranged between a minute wheel tube and the minute wheel blade, and a second stop rod which can be connected or disconnected with a second stop electrode is also arranged in front of the handle shaft. The clutch lever part is omitted, so that a second wheel, the third wheel and the minute wheel always stay at a precise engagement state, and the time travel reliability of the clock mechanism can be improved; and meanwhile, the elastic connection structure which can rotate relatively is arranged between the minute wheel tube and the minute wheel blade, so that precision in time travel still can be guaranteed, and a function for high efficiently correcting the hour and the minute can be realized under the situation that the needle shifting intermediate wheel is omitted.

Description

technical field [0001] The invention relates to a quartz watch movement, in particular to a quartz watch movement which omits a clutch lever and a dial intermediate wheel. Background technique [0002] Quartz electronic watches are favored by people for their advantages of accurate travel time, beautiful appearance and eliminating the need for operations such as mechanical watch tightening, but because of the motor, gear train mechanism and other circuit components installed inside the watch case, the space inside the watch case is limited. Large compression, therefore, making full use of the narrow shell space, reducing shell components, reducing component wear and developing more functions has always been a major topic of research and development in the industry, and it is the development direction people are pursuing, especially the stop second clutch mechanism. [0003] Such as figure 1 , 3 , 4, and 5, the second-stop clutch mechanism includes the stem, clutch lever, ...

AI Technical Summary

Problems solved by technology

[0014] 2) In the above-mentioned first stop-second clutch mechanism, whenever the hour and minute are adjusted, the passing wheel will be inclined due to the displacement of the clutch lever. After the adjustment is completed, the meshing with the second wheel and the minute wheel will be resumed. This is the case for a long time, and the frequent inclination The action will cause the upper and lower tenons of the wheel shaft to deform, thereby reducing the reliability of the movement time

[0015] 3) In the above-mentioned second stop-seconds clutch mechanism, a setting intermediate wheel component is arranged between the setting wheel and the span wheel, thus resulting in an increase in the material cost of the watch
