Description
Technical field
The utility model relates to a kind of mechanical timer, especially a kind of timer that has wobble frequency switching mechanism.
Background technology
The timer that has escapement in the prior art mainly comprises driving mechanism, escapement and balance mechanism, and driving mechanism comprises the great wheel that has clockwork spring, and escapement comprises escape wheel and escapement lever, and balance mechanism comprises the escapement that has hairspring.After screwing clockwork spring, great wheel is rotated and is transferred a torque to escape wheel by a plurality of gears, escape wheel rotates and contacts slidably with escapement lever, driving escapement lever swings around the escapement lever center pillar, the escapement lever of swing is swung with certain frequency by the Ma Kou and the secondary troughed belt movable pendulum wheel of its end, thereby equably with the moment of torsion in the specific ripple frequency release clockwork spring.
For the high timer of ripple frequency, in certain time length, the angle that its timing wheel rotates on Users panel is big, the timing accuracy height; And the low timer of ripple frequency is in certain time length, and the angle that timing wheel rotates on Users panel is little, and timing accuracy is little, but but timing prolong.Just because of this, traditional timer is divided into two kinds of long-time timer and short time timers.But long-time timer timing is longer, but timing accuracy is relatively poor; Short time timer timing accuracy is better but but timing is not long.This traditional timer can not satisfy the needs of user's timing length and timing accuracy simultaneously, when the user needs regularly the time period of different length, often needs to use the different timing device, and not only trouble has also caused waste to a certain degree.
Summary of the invention
The utility model purpose provides a kind of multisection type timer, and it has different ripple frequencies on the different sections of timing panel, can satisfy the different needs of user's timing length and timing accuracy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multisection type timer, its timer body comprises the driving mechanism that is arranged on the clamping plate, escapement and balance mechanism, described driving mechanism comprises the great wheel that has clockwork spring, described escapement comprises escape wheel and escapement lever, described balance mechanism comprises the escapement that has hairspring, described great wheel is provided with the great wheel axis and great wheel is joined by transmission mechanism and escape wheel transmission, described escape wheel contacts slidably with escapement lever, described escapement lever is provided with the escapement lever center pillar and escapement lever contacts slidably with escapement, described timer body also comprises wobble frequency switching mechanism, described wobble frequency switching mechanism comprises adjustable lug, cam and stopping means, described adjustable lug has projection and which is provided with flexible connection mechanism, described adjustable lug is pivotally connected by reference column and clamping plate, one end of described escapement lever center pillar is arranged on the adjustable lug, described cam has a wheel edge and the wheel edge that radius is less that radius is bigger at least, and cam is arranged on the great wheel axis regularly, the end position of the corresponding escapement lever center pillar of described clamping plate is provided with cell body, described stopping means is arranged on the clamping plate and with a side of adjustable lug and contacts slidably, described adjustable lug be raised to rare two service positions: first service position is that the projection of described adjustable lug withstands on the bigger wheel of radius along last, and second service position is that the projection of adjustable lug withstands on the less wheel of radius along last.
Described stopping means is a positive stop, and it contacts slidably with a protruding relative side of adjustable lug.
Described flexible connection mechanism is extension spring, and itself and escapement lever center pillar are separately positioned on the both sides of reference column.
Described flexible connection mechanism and escapement lever center pillar are separately positioned on the both sides of reference column.
Because technique scheme utilization, the utility model compared with prior art has following advantage: when adjustable be in first service position promptly projection withstood on the bigger wheel of cam radius when last, timer is in section at a slow speed, escapement lever contacts slidably with locking face, the impulse face of escape wheel, escapement is with low ripple frequency swing, and this moment, timer can be used as long-time timer; When adjustable lug be in second service position promptly projection withstood on the less wheel of cam radius when last, under the effect of extension spring and positive stop, adjustable lug turns over certain angle around its reference column, thereby an end of escapement lever moves a certain distance along the direction away from escape wheel, distance between escapement lever and the escape wheel becomes big, escapement lever only contacts slidably with the impulse face of escape wheel, shorten time of contact, escapement is swung with high ripple frequency, this moment, timer can be used as the short time timer, and timing accuracy is higher.
