Problems solved by technology
The 30-minute / lap chronograph has certain limitations for the wearer. When the one-time timing time exceeds 30 minutes, the scoring dial cannot be displayed at one time, and the wearer needs to superimpose the calculation time. In addition, the existing structure has low-grade practical problems
On the premise that the eye positions of the scoring and seconds pointers are determined, in order to realize the scoring function of 60 points / lap, if the scoring wheel assembly adopts the style of the original scoring (30 points / lap) mechanism, the direct transmission structure of the wheel train The number of teeth and modulus of the middle split wheel will increase accordingly, and the disadvantages brought about by this: the structure of the shift spring is changed, the processing of the shift spring is poor, the positioning of the point positioning spring rod is not accurate, and the reliability of the scoring mechanism is poor.

The invention discloses a minute-counting transmission mechanism, comprising a second-counting wheel assembly, a minute setting wheel assembly, a minute-counting wheel assembly and a minuet -positioning spring rod. The second-counting wheel consists of a second-counting shaft, a shifting spring, a second-counting wheel sheet, and a second-counting peach-shaped wheel, and the second-counting shaft, the second-counting wheel sheet and the second-counting peach-shaped wheel are integrated through fixing; the shifting spring and the second-counting wheel sheet are fixedly integrated by forming a relative angle of being 50-52 degrees; the minute setting wheel assembly consists of a minute setting wheel, a minute setting wheel sheet and a minute setting wheel shaft; the minute setting wheel is fixedly integrated with the minute setting wheel sheet and then is fixed on the minute setting wheel shaft; the relative angle of the minute setting wheel and the minute setting wheel sheet is 2-4 degrees; the minute-counting assembly consists of a minute-counting wheel shaft, a minute-counting peach-shaped wheel and a minute-counting wheel sheet; the minute-counting peach-shaped wheel and the minute-counting wheel sheet form a relative angle of being 4.8-6.8 degrees, and the minute-counting wheel sheet has 60 teeth; and the biggest radius of the fillet of the working portion of the minute-positioning spring rod is 0.05 mm. The scoring transmission mechanism (60 min / per round) of the multifunctional stopwatch improves the single-round minute-counting time, and improves the reliability of the movement and the grade of the movement.
Description
technical field [0001] The invention relates to the technical field of clocks and watches, in particular to a scoring transmission mechanism. Background technique [0002] When the domestic existing chronograph function is started, the reaction is that the minute hand rotates a circle for 30 minutes on the scoring dial. The 30-minute / lap chronograph has certain limitations for the wearer. When the one-time timing time exceeds 30 minutes, the scoring dial cannot be displayed at one time, and the wearer needs to superimpose the calculation time. In addition, the existing structure has low-grade practical problems . On the premise that the eye positions of the scoring and seconds pointers are determined, in order to realize the scoring function of 60 points / lap, if the scoring wheel assembly adopts the style of the original scoring (30 points / lap) mechanism, the direct transmission structure of the wheel train The number of teeth and the modulus of the middle splitter wheel w...
