Description
Technical field
This utility model relates to mechanical watch technical field, is specially a kind of hair-spring balance adjusting means.
Background technology
Hair-spring balance conventional with in stem-winder, in hair-spring balance hairspring function as a spring, constantly absorb during swinging and release kinetic energy, so that escapement constantly swings.In existing hair-spring balance structure, trouble installed by hairspring and escapement, the accuracy of the initial position of escapement is difficult to hold, escapement is easily made to stop, index lever is generally used to regulate in speed governing loop, the regulation of index lever adjusts the active length of hairspring exactly, because if active length shortens, the rigidity of hairspring increases, and swing speed can be accelerated, otherwise will slow down, it is used for accuracy when adjusting away, and the range of accommodation of existing index lever regulation method does not often reach requirement, and easily loosen during life-time service, cause the effect not having regulation.
Utility model content
The purpose of this utility model is to provide a kind of hair-spring balance adjusting means, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of hair-spring balance adjusting means, including mounting disc and hairspring, index lever mounting seat it is provided with in the middle part of the upper surface of described mounting disc, it is socketed with annulus in described index lever mounting seat, the upper surface of described annulus has limiting through hole, it is provided with lid at the upper end open of described limiting through hole, the outer wall of described annulus is provided with index lever, the upper surface of described mounting disc is fixedly connected with U-shaped spring leaf by screw, and the top of index lever is plugged on the inner chamber of U-shaped spring leaf, it is provided with bolt on described U-shaped spring leaf, and the outer wall laminating of the left side of bolt and index lever, described hairspring is positioned at the upper surface of mounting disc, one end of described hairspring is provided with first and fixes ball, the other end of described hairspring is provided with second matched with limiting through hole and fixes ball.
Preferably, the sidewall of described limiting through hole leaves perpendicular type groove, and the body of hairspring is through the inner chamber of perpendicular type groove.
Preferably, the outer wall of described index lever leaves groove, and the end of bolt is plugged on the inner chamber of groove.
Compared with prior art, the beneficial effects of the utility model are: this hair-spring balance adjusting means, index lever is used to be plugged on the inner chamber of U-shaped spring leaf, and the structure of bolt is set on U-shaped spring leaf, swivel bolt, drive index lever rotates, thus reach to control the active length of hairspring, the active length of hairspring shortens, the rigidity of hairspring increases, swing speed can be accelerated, otherwise will slow down, it is used for accuracy when adjusting away, range of accommodation is wide, and owing to spring leaf has certain elasticity, it is not susceptible to loosen, durability is superior, the head and the tail two ends of hairspring are provided with fixing ball, only fixing ball need to be inserted when assembling and the limiting through hole set just can complete the fixing of hairspring, assembling is simple, this hair-spring balance adjusting means range of accommodation is wide, it is easily installed, good stability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is A portion of the present utility model schematic enlarged-scale view.
In figure: 1 mounting disc, 2 index lever mounting seat, 3 hairsprings, 4 first fix ball, 5 screws, 6 bolts, 7U type spring leaf, 8 index levers, 9 annulus, 10 lids, 11 limiting through hole, 12 second fix ball.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2，A kind of technical scheme of this utility model offer: a kind of hair-spring balance adjusting means，Including mounting disc 1 and hairspring 3，Index lever mounting seat 2 it is provided with in the middle part of the upper surface of mounting disc 1，Annulus 9 it is socketed with in index lever mounting seat 2，The upper surface of annulus 9 has limiting through hole 11，Lid 10 it is provided with at the upper end open of limiting through hole 11，The outer wall of annulus 9 is provided with index lever 8，The upper surface of mounting disc 1 is fixedly connected with U-shaped spring leaf 7 by screw 5，And the top of index lever 8 is plugged on the inner chamber of U-shaped spring leaf 7，It is provided with bolt 6 on U-shaped spring leaf 7，And the outer wall laminating of the left side of bolt 6 and index lever 8，Swivel bolt 6 drives index lever 8 to rotate，Thus reach to control the active length of hairspring，The active length of hairspring shortens，The rigidity of hairspring 3 increases，Swing speed can be accelerated，Otherwise will slow down，The outer wall of index lever 8 leaves groove，And the end of bolt 6 is plugged on the inner chamber of groove，Avoid because of under the effect of external force，There is lateral displacement in bolt 6 index lever 8，Bolt 6 is caused to separate with index lever 8，Whole adjusting means is caused to lose efficacy，Hairspring 3 is positioned at the upper surface of mounting disc 1，One end of hairspring 3 is provided with first and fixes ball 4，The other end of hairspring 3 is provided with second matched with limiting through hole 11 and fixes ball 12，The sidewall of limiting through hole 11 leaves perpendicular type groove，And the body of hairspring 3 is through the inner chamber of perpendicular type groove，More firm is fixed together hairspring 3 with annulus 9，Promote the stability of this device.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
