Summary of the invention

In order to overcome the above problem, the utility model provides one kind and can install in order to machine core, and second wheel axis can be prevented from the second It is detached from gear, while low-cost quartz clock watch and clock movement.

To achieve the above object, the technical solution that the utility model provides is:

A kind of quartz clock watch and clock movement, including second gear and second wheel axis, second gear are equipped with the mounting hole of second wheel axis, second wheel Axis may pass through the positioning that mounting hole is formed in second gear in machine core；The second wheel axis by way of die casting second wheel axis at least It is non-circular limiting section that cross section is formed on one end, and the distance that limiting section at least has two o'clock on cross section is greater than The internal diameter of second pinion mounting holes.

In the limiting section insertion second pinion mounting holes.

The second pinion mounting holes divide equally three sections, including upper section, middle section, lower section, and the limiting section is located at the installation of second gear The middle section in hole.

Above-mentioned technical proposal has the beneficial effect that

1. the utility model provides a kind of quartz clock watch and clock movement, due to being to form the second on second wheel axis by the way of die casting The limiting section of gear compares traditional lathe mode using die casting mode, and low in cost, the cost of entire second wheel axis only needs 1.8 point；And since the cross section of non-circular agretope is there are two the internal diameter that the distance put is greater than second pinion mounting holes, thus may be used It falls off to avoid in the correction course of second hand, second wheel axis runs through from second pinion mounting holes.

2. since the end die casting of second wheel axis is non-circular, so the frictional force of second wheel axis and second gear is multiple directions , and the direction of each frictional force is not on the same line, so second wheel axis is capable of forming multi-angle with the contact of second gear Friction fit, form the frictional force of multiple directions, then form the friction Force system mutually restrained, so can be in axial direction It is upper to obtain metastable structure, so that second wheel axis is difficult to be detached from from second pinion mounting holes.

3. compared to the technical solution that background technique uses lathe process second wheel axis, due to needing to get on the bus appearance in second wheel axis Rank, to ensure that second wheel axis is capable of fixing in Installing Plate, therefore the mounting hole that second wheel axis is corresponded in Installing Plate is also required to Expanding treatment is done, production cost is further increased；And the utility model is the portion progress die casting in second wheel axis, second wheel axis The diameter at both ends does not change, so not needing to carry out Installing Plate additional working process.

4. it is that a metal shaft is processed into second wheel axis during lathe process second wheel axis, it can not in process The meeting avoided falls some materials, causes the waste of steel, since machine core has enough sales volumes, therefore what the processing of second wheel axis was wasted Material be it is very considerable, the discharge of coolant liquid will also result in pollution in process；And the die casting mode that the utility model uses can To overcome these problems completely, it not only further reduced production cost, more can protect environment.

It is clearly and completely described below in conjunction with technical solution of the attached drawing to the utility model, it is clear that described implementation Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, ordinary skill Personnel's every other embodiment obtained without making creative work belongs to the range of the utility model protection.
