One class is traditional castle wheel, trip(ping) lever, draw compositions such as shelves, stage clip (a fixed shelves spring) and arbor.Utilize minute wheel and divide the friction structure of tooth axle to pull out pin.
Another kind of is that third wheel (four-wheel) axis hole designs on a rocking bar, and an end of rocking bar is sleeved on (as rotation center) on the clamping plate post, the other end and arbor resilient connection.When arbor was extracted, rocking bar was crossed axle hole and is turned an angle around fixing clamping plate under resilient force, makes axle tooth and minute wheel drop out of gear, and arbor then drives and pulls out the upright wheel → back gear of pin → hour wheel and minute wheel rotation, thereby has realized pulling out pin.Its arbor is to realize axial location by arbor back stop (generally being produced on the movement cover plate).This structure is the earliest by the NSK design, and domestic many movements adopt, and are well-known, discuss no longer in detail.
The first kind is a traditional structure, because the moment of friction of friction minute wheel is controlled at suitable difficulty is arranged on the technology, and part processing precision is had relatively high expectations, so the second class plucking machine structure is used more and more in recent years.But the second class plucking machine structure also has shortcoming: pull out the upright wheel of pin and often nibble with back gear, (the non-pin position of pulling out) back gear drives and to pull out the upright wheel of pin and dally on arbor during the movement operate as normal, consumed part energy in vain, reliability in the time of also can influencing movement and normally walk (at this moment arbor with pull out the upright wheel of pin be clearance fit), when arbor is in when pulling out the pin position, arbor is an interference fit with pulling out the upright wheel of pin, arbor leans on the magnitude of interference (circle) drive to pull out the upright wheel of pin and rotates, and the requirement of both axis hole machining precisioies is quite strictness also.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of quartz watch plucking machine structure, and it is more smooth to pull out pin with order, and the reliability when guaranteeing that movement is normally walked.
Secondary objective of the present utility model is to provide a kind of quartz watch plucking machine structure, has simultaneously to end a second electricity-saving function.
To achieve these goals, solution of the present utility model is:
A kind of quartz watch plucking machine structure, by castle wheel, trip(ping) lever, draw shelves, stage clip and arbor to form, the arbor upper milling position, the mesopore of castle wheel is a square, castle wheel and arbor cooperate by square shaft and square hole, and castle wheel is in the axis move left and right of trip(ping) lever effect lower edge arbor, and two positions of trip(ping) lever are by drawing the control of shelves and arbor, realize castle wheel and back gear from, close two states, the axle hole of crossing of train is arranged on the arm of trip(ping) lever.
Trip(ping) lever as ending a second battery saving arrangement, has been provided with a hemispherical protuberances simultaneously in the above-mentioned plucking machine structure in the end of trip(ping) lever, and the bottom of ending second post on the circuit board also is hemispheric.
After adopting said structure, the utility model integrated application the advantage of two class plucking machine structures, still adopt traditional castle wheel, trip(ping) lever, draw shelves, the traditional structure of stage clip and arbor, arbor and castle wheel are fixed, the axial location of arbor is by drawing the shelves decision, third wheel (four-wheel) axis hole with train is arranged on the arm of trip(ping) lever simultaneously, when arbor dials out to when pulling out the pin position, trip(ping) lever drives castle wheel and directly meshes back gear (not pulling out pinwheel), simultaneously because the rotation of trip(ping) lever, four-wheel (third wheel) axis hole also turns an angle around the trip(ping) lever axle, the axle tooth that makes third wheel thereupon with the minute wheel drop out of gear, at this moment corresponding the rotation with arbor of arbor → castle wheel → back gear → hour wheel and minute wheel rotated, and realizes pulling out pin smoothly, because do not rub minute wheel, minute wheel and split axle tooth are integral molded plastics, because the axle tooth of minute wheel and third wheel is a drop out of gear when pulling out pin, it is very little to pull out the needle force square again, so it is more smooth to pull out pin.And, in overall design, removed and pulled out pinwheel, reduced by a part, the more important thing is and normally walk constantly that hand train wheel and plucking machine structure are complete drop out of gears, improved the global reliability of movement work.
In addition, the utility model is because trip(ping) lever is simultaneously as ending a second battery saving arrangement, is provided with the hemispherical protuberances that cooperatively interacts and hemispherical in the end of trip(ping) lever and the bottom of ending second post.When trip(ping) lever is in when pulling out the pin position, two hemispheres contact, and certain axial magnitude of interference is arranged, and promptly there is certain axial deformation the end of trip(ping) lever, guarantees the reliability that both contact, and have realized that electricity ends second and the economize on electricity effect.
