Problems solved by technology
However, in the process of realizing disengagement, a large load will be formed on the automatic system, which will cause a burden on the automatic hammer of the movement, thereby affecting the winding efficiency and reducing the automatic winding efficiency; especially on thin or small automatic movements, due to the size Requirements, the smaller the automatic hammer has a great impact on the winding efficiency, so the disengagement device is particularly important, but due to the limitation of the movement space, the disengagement function cannot be realized on the movement

Embodiment Construction
[0021] Below, the present invention is described in further detail in conjunction with accompanying drawing and specific embodiment:
[0022] Such as Figure 1 to Figure 7 As shown, the automatic winding disengagement mechanism of the watch of the present invention is arranged on the watch case, including the watch case part 1, the stem assembly 4 and the crown part 11; the stem assembly 4 passes through the watch case part 1 and the handle The head part 11 is connected as a whole. The watch case part 1 includes a watch case 2 and a handle 3 that are pressed together, and the handle 3 is formed with external threads; the stem assembly 4 includes an stem 5, a stem square core 6, and an stem extension shaft 7. Arbor bushing 8, the first pin 9 and the second pin 10, the stem 5 is pressed together with the square core 6 of the stem, and fixed by the first pin 9, the extension shaft 7 of the stem is connected to the bushing of the stem 8 are pressed together and fixed by the seco...

The invention discloses a watch automatic winding releasing mechanism. The releasing mechanism is arranged on a watch case, and comprises a watch case part, an arbor assembly and a head part; the arbor assembly penetrates the watch case part to be connected with the head part; the watch case part comprises the watch case and a crown tube compressed in one body; the arbor assembly comprises an arbor and an arbor square core fixed integrally through a first pin, and an arbor extension shaft and an arbor sleeve pipe fixed integrally through a second pin; the head part comprises the head and a head core compressed in one body; the head is screwed on the arbor extension shaft; the crown tube is connected with the head core. The beneficial effects are that the releasing mechanism is arranged on the watch case and realized through the arbor and a watch crown structure, thus effectively solving the problems of failure to assemble the releasing mechanism because of an insufficient core space; and in particular, when the core is automatically wound, the arbor can automatically rotate, so the releasing can be achieved simply by overcoming a small force, i.e., a friction between the arbor and a vertical wheel.
Description
technical field [0001] The invention relates to a disengagement mechanism of a watch, in particular to a disengagement mechanism of an automatic winding watch. Background technique [0002] In the watch self-winding movement, the stem shaft is fixed due to the crown, so the front valve neutral wheel has to overcome the force of the clutch lever spring and the friction between the clutch wheels to achieve disengagement. Therefore, the winding ratchet to the vertical wheel There is a separate disengagement structure in the engaging line. However, in the process of realizing disengagement, a large load will be formed on the automatic system, which will cause a burden on the automatic hammer of the movement, thereby affecting the winding efficiency and reducing the automatic winding efficiency; especially on thin or small automatic movements, due to the size Requirements, the smaller the automatic hammer has a great impact on the winding efficiency, so the disengagement device ...
