Abstract (en)
[origin: CN220040974U] The utility model relates to a speed regulating mechanism (1) used for a clock movement, the speed regulating mechanism comprises an inertia mass body such as an annular balance wheel (23), a hairspring (25) and a fast and slow pointer assembly system (20) used for adjusting the travel time difference of the hairspring, and the hairspring comprises a coiled strip (2) and an adjusting device used for adjusting the rigidity of the hairspring. The adjusting device is provided with a flexible elastic element (5) arranged in series with the coiled strip, the fast and slow needle assembly system comprises a stud holder (31) comprising a first stud (34) and a second stud (35), characterized in that the flexible elastic element (5) is arranged between the first stud and the second stud, and the flexible elastic element (5) is arranged between the first stud (34) and the second stud (35). The first stud is movable relative to the second stud, the movement of the first stud changing the stiffness of the hairspring. The utility model also relates to a clock movement comprising the speed regulating mechanism, and a clock comprising the clock movement.
Abstract (fr)
L'invention se rapporte à un organe réglant (1) pour mouvement d'horlogerie comprenant une masse inertielle, par exemple un balancier (23), un ressort-spiral (25), et un système de raquetterie (20, 60) pour ajuster la marche du ressort-spiral (25), le ressort-spiral (25) comprenant un ruban enroulé (2) et des moyens d'ajustement de la raideur du ressort-spiral dotés d'un élément élastique (5) agencé en série du ruban enroulé (2). La raquetterie comporte un dessin et des repères configurés pour ajuster la marche de l'organe réglant avec une résolution inférieure ou égale à 1 seconde par jour.
