Description
Technical field
The present invention relates to there is card degree stem-winder technical field, more particularly to one kind has card degree escapement to lock fine time adjustment
Mechanism.
Background technology
Adjustment mechanism is made up of moveable stud and index lever when being walked by card degree stem-winder escapement, due to stud and soon
Slow pin is not fixed, and is often caused in use because the external force factor such as knocking, touching：(1) stud produces displacement, and makes wrist-watch
There is isochronal error and cause beat phenomenon；(2) index lever produces displacement, and the hairspring length effectively utilized is changed,
Occurs fast or slow phenomenon when wrist-watch is walked.In addition, the index lever of adjustment mechanism is for convenience of adjusting when having the card degree stem-winder escapement to walk
, there is certain interval in school between hairspring and index lever clip, so result in hairspring and paste inner clip sometimes during vibrations, paste outer sometimes
Folder, either only patch side presss from both sides or does not paste folder, so that the real work length of hairspring changes at any time, causes escapement
The vibrations cycle is unstable, causes wrist-watch inaccurate when walking.
The content of the invention
The invention aims to solve shortcoming present in prior art, and the one kind proposed has card degree escapement to lock
Tight fine time adjustment mechanism, accuracy when more conducively adjustment wrist-watch is walked.
To achieve these goals, present invention employs following technical scheme：
One kind has card degree escapement to lock fine time adjustment mechanism, including balance cock, hairspring stud, hairspring, anti-rattler, pendulum

Fastening screw in ring-type elongated hole can be locked on balance cock, and the index lever mechanism is connected by speed needle body, hairspring holder, index lever
The fine adjustment screw composition of bar and unwarranted charge small eccentricity axle, the hairspring stud, speed needle body and index lever connecting rod pass through anti-rattler set
On balance cock, the hairspring is located in hairspring holder, and the outer end of hairspring is fixedly connected with hairspring stud.
It is preferred that, the hairspring holder is made up of a hairspring lock valve and the dynamic lock valve of a hairspring.
It is preferred that, the hairspring lock valve is rectangular structure, and its medial surface is the concave circular arcs face concentric with hairspring,
It is provided with the spill gathering sill perpendicular to cambered surface, the bottom surface of the hairspring lock valve and is being oriented in the middle of the bottom surface adjacent with arc-shaped edges
The both sides of groove are provided with valve rivet is determined, and the hairspring lock valve is fixedly connected on speed needle body by determining valve rivet.
It is preferred that, the dynamic lock valve contact surface of the hairspring is on the convex shaped arc face concentric with hairspring, the convex shaped arc face
Leading arm provided with rectangular-shape, the leading arm can be moved freely in gathering sill, end of the leading arm away from cambered surface
Provided with a screw hole, the dynamic lock valve of the hairspring by the screw connection that is located in screw hole on speed needle body, the leading arm
The other end be provided with an elongated hole, eccentric screw is provided with the elongated hole.
It is preferred that, the index lever connecting rod includes annular body, and the top outer of the annular body is long provided with an annular
Hole, the index lever connecting rod is connected on speed needle body by the locking of screw II being located in annular elongated hole, the annular body
Bottom be the swing arm of two fork-shapeds, tip inside and the fine adjustment screw Elastic Contact of the swing arm.
It is preferred that, including following job step：
First, isochronism is adjusted：Fastening screw, screw I, eccentric screw are unscrewed, eccentric screw makes hairspring be in free state,
Mobile hairspring stud, adjusts the isochronism (not beat) of escapement, then screw eccentric screw, screw I, fastening screw；
2nd, coarse adjustment：Screw II and screw I are unscrewed, then turn eccentric screw makes the dynamic lock valve of hairspring leave hairspring lock valve, moves
Dynamic speed needle body opponent's table is carried out after coarse adjustment when walking, screwing screw II, and it is fixed that turn eccentric screw makes the dynamic lock valve of hairspring be adjacent to hairspring
Lock valve and clamp hairspring, then screwing screw I；
3rd, finely tune：Screw I is unscrewed, then turn eccentric screw makes the dynamic lock valve of hairspring leave hairspring lock valve, then pass through turn
Fine adjustment screw, promotes index lever connecting rod, and the trickle adjustment of position is carried out to speed needle body.
In the present invention, by setting up circular elongated hole on hairspring stud, hairspring stud is not only fixed but also be easy to regulation,
By using the hairspring holder of separable adjustment, can press from both sides hairspring and hairspring holder attached firm, be prevented effectively from because wrist-watch collide with etc. it is various
The problem of reason causes the escapement vibration period caused by hairspring real work length change unstable, and it is easy to index lever position
The Fast Coarse quasi- adjustment put, adjusts the position of index lever connecting rod by using the fine adjustment screw of unwarranted charge small eccentricity axle, can be achieved fast
The thin quasi- adjustment of slow needle body position, it is rational in infrastructure, improve the efficiency of accuracy adjustment when wrist-watch is walked.
