Abstract
The utility model discloses a mechanism for preventing the pointing component of a watch from swinging. The mechanism comprises a gear, indicator wheel components and pointers, wherein, the indicator wheel components comprise an indicator wheel, a return spring, a spring fixing piece and a spring fixing stub; an inside stud and the indicator wheel which rotate coaxially are laminated into an integration; one end of the return spring is fixedly connected with the inside stud, and the other end thereof is connected with the spring fixing stub on the spring fixing piece; the gear is meshed with the indicator wheel; and the pointers are fixedly mounted at the upper end of the indicator wheel coaxially, and rotate with the indicator wheel coaxially. The utility model has the beneficial effects that the teeth of the indicator wheel is clung to the teeth side of the gear all along due to the elastic force of the return spring during the transmission process of the gear, so that the swinging phenomenon of the pointers or digital pointing is eliminated. The mechanism further has the advantages of simple and reliable structure, less energy consumption of the movement, easy processing and low cost.
Description
Technical field
The utility model relates to a kind of indicating mechanism of wrist-watch, particularly a kind of mechanism that prevents the watch hand swing.
Background technology
Along with the variation day by day of wrist-watch indicating mechanism, watch displays also becomes and more and more comes novelty, dynamic.No matter be the display structure of pointer-type, still the display structure of numerical aperture formula is generally realized by gear drive, and need there be certain clearance in meshed transmission gear when requiring to mesh between the gear, to guarantee the normal rotation of gear, as shown in Figure 3 and Figure 4.But there is following shortcoming in this gear drive, in transmission process because the gap of flank, in the gear drive process, can produce the backlash amount, be in relative free state between gear 1 and the indicator wheel 2a, under the situation of wrist-watch vibrations, indicator wheel 2a can shake along with vibrations, swings thereby drive pointer 3, influences the visual effect of wrist-watch.
Summary of the invention
Problem to be solved in the utility model is, overcomes the prior art shortcoming, provides a kind of when wrist-watch vibrations or orientation change, and prevents that the anti-locking mechanism of indication of swing from appearring in pointer, numeral indication.
The technical solution adopted in the utility model is: a kind of anti-locking mechanism of indication swing of wrist-watch comprises: gear, indicator wheel assembly and pointer; Described indicator wheel assembly is made up of indicator wheel, return spring, solid reed parts and solid spring stake; Stake is an one with the indicator wheel pressing in described, and coaxial rotation; One end of described return spring is fixedlyed connected with interior stake, and the other end is fixed with the solid spring stake on the solid reed; Described gear and indicator wheel engagement, the coaxial fastening upper end that is installed in indicator wheel of described pointer is with the coaxial rotation of indicator wheel.
Described return spring is a hairspring.
Described gear and solid reed are fixed with base plate respectively.
The beneficial effects of the utility model are: in the transmission process of gear because the elastic force of return spring, make the teeth of indicator wheel be fitted in gear teeth one side all the time, eliminated the dancing that pointer, numeral are indicated, this is simple in structure, reliable, the energy that consumes movement is less, be easy to processing, cost is low.

Embodiment
Below, be described in further detail with the anti-locking mechanism of indication swing of embodiment in conjunction with the accompanying drawings the utility model wrist-watch:
As depicted in figs. 1 and 2, the anti-locking mechanism of the indication of the utility model wrist-watch swing comprises: gear 1, indicator wheel assembly 2 and pointer 3; Described indicator wheel assembly 2 is made up of indicator wheel 2a, return spring 2b, solid reed parts 2c and solid spring stake 2d; Described gear 1 has fly back mechanism, fixes with base plate respectively with solid reed 2c; Stake is an one with indicator wheel 2a pressing in described, and coaxial rotation; The end of described return spring 2b is fixedly connected in the interior stake, solid spring stake 2d on the other end and the solid reed 2c fixes, the effect of return spring 2b is the trend that makes gear 2a have the side tooth with gear 1 to keep in touch under the elastic force effect of return spring 2b forever, eliminated the backlash amount between gear 1 and the indicator wheel 2a, reach the purpose that prevents pointer indication swing, described return spring 2b is a hairspring, the number of turns of return spring can not be very few, the number of turns very little can be very hard, consume the energy of wrist-watch, the number of turns can take the too much space of wrist-watch too much, influences the setting of other parts, therefore the number of turns can be provided with as required voluntarily, and it is all right only to need to guarantee to make pointer to be adjacent to teeth one side of gear; The described pointer 3 coaxial fastening upper ends that are installed in indicator wheel 2a are with the coaxial rotation of indicator wheel 2a.
Indication swing to the utility model wrist-watch prevents that working process of mechanism from specifying below doing below:
The utility model is by the transmission of wrist-watch basis movement, driven gear 1 is rotated counterclockwise, gear 1 drives indicator wheel 2a and turns clockwise, return spring 2b is associated with indicator wheel 2a by interior stake, indicator wheel 2a has the trend of close gear 1 gear teeth all the time under the elastic force effect of return spring 2b, indicator wheel 2a continues to turn clockwise, until a side wheel tooth, finish a transmission near gear 1.Adopt this structure can be owing to the existence in gap between the gear teeth of gear 1 and indicator wheel 2a when wrist-watch shakes, and the phenomenon of pointer shake takes place, corresponding pointer 3 also can not given birth to swing.
It is worthy of note; according to basic fundamental design of the present utility model; those of ordinary skills need not through creative work; with regard to attainable as with the band that this structure can be used for mechanical watch and crystal-oscillator watch return the indicating mechanism of function such as calendar, Zhou Li, monthly calendar, year calendar, 24 o'clock and show can mechanism or the like, protection domain of the present utility model is as the criterion with claim.
