Description

Timepiece movement

Technical field

This utility model is related to timepiece movement technical field and in particular to timepiece movement.

Background technology：

Wrist-watch, or referred to as watch, refer to the instrument being worn in wrist, in order to timing and showing the time.Typically utilize skin The materials such as leather, rubber, nylon cloth, rustless steel, make watchband, and " gauge outfit " of display time is restrainted in wrist.Originally it is used as instrument Should the carrying by golden word of device, but Chinese character simplified is simplified to table.First wrist-watch in the world is to be reached by hundred in 1868 Bird with red feathers is beautiful to be manufactured to Hungarian Koscowicz countess's.But the clock and watch of this form are not popular at that time.Wrist-watch Universalness will be postponed to earlier 1900s.Cartier, formally by the clock and watch commercialization of this form, is proposed famous within 1911 Santos wrist-watch.Henceforth, wrist-watch just starts to popularize.

Wrist-watch operation principle, wrist-watch is used to a kind of precision instrument of instruction time, and the principle of this instrument is using one Constant period, sustained vibration vibrational system is as standard.If it is known that vibrational system completes once required for full vibration Time (vibration period), and calculate vibration number, then, vibration so repeatedly after time of being experienced be equal to vibrate Cycle is multiplied by vibration number.

In general timepiece movement can be divided into two big class：Stem-winder and electronic watch.And stem-winder is common also two groups, Armstrong's patent table and automation table

Stem-winder second hand is uninterruptedly to walk.Because mechanical watch movement is complicated, walking time error larger (depending on various brands Fixed), observatory's movement error is less, and the error of a day is normal within the -4/+6 second.Stem-winder walking time error can not add up, handss Table needs testing and measuring technology fine after a while, and easy to use, fully-wound can walk more than 36 hours.Movement service life is permanent. Outward appearance more thick and heavy than quartz watch (depending on various brands), has some brands also very thin, but typically all armstrong's patent table.

Movement in existing stem-winder is typically all engaged by gear, passes through to catch only between escape wheel and escapement Vertical fork connects, and escapement lever is all directly to coordinate with escape wheel, and life-time service can lead to wear and tear, once abrasion, then will change and catch Vertical fork, such replacement cost is high, and can affect the overall operation accuracy of movement.

Utility model content

For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of reasonable in design, motility Good, replacing is convenient, the accurate timepiece movement of precision.

Timepiece movement of the present utility model, it comprises small click wheel, big click wheel, driving wheel on barrel, third wheel, second wheel, centre wheel, pendulum Wheel, escape wheel, escapement lever, counterpart；Described small click wheel is engaged with big click wheel；Described big click wheel is arranged on the upper of driving wheel on barrel Side；The side of described driving wheel on barrel is provided with third wheel；The top of described third wheel is engaged with centre wheel by little gear；Described mistake Wheel is engaged with the little gear of second wheel bottom；Described second wheel is engaged with escape wheel；It is provided between described escape wheel and escapement and catch Vertical fork；The movable end of described escapement lever is provided with counterpart；Described counterpart is plugged in the furcation of escapement lever, and counterpart Cooperate with the external gear of escape wheel.

Preferably, described counterpart and escapement lever are interference fit, good stability, it is easy to dismount.

During this utility model operation, counterpart is coordinated with escapement lever, and when producing abrasion, counterpart active is worn, to protect Full escape wheel, and do not interfere with escapement lever, improve overall service life.

The beneficial effects of the utility model：Its reasonable in design, easy to use, motility is good, good stability, and wearing and tearing is Single, replacement cost is low, long service life.

Brief description

For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.

Fig. 1 is structural representation of the present utility model；

In figure：

Small click wheel 1, big click wheel 2, driving wheel on barrel 3, third wheel 4, second wheel 5, centre wheel 6, escapement 7, escape wheel 8, escapement lever 9, join Component 10.

Specific embodiment

As shown in figure 1, this specific embodiment employs the following technical solutions：It comprises small click wheel 1, big click wheel 2, driving wheel on barrel 3rd, third wheel 4, second wheel 5, centre wheel 6, escapement 7, escape wheel 8, escapement lever 9, counterpart 10；Described small click wheel 1 and big click wheel 2 Engagement；Described big click wheel 2 is arranged on the top of driving wheel on barrel 3；The side of described driving wheel on barrel 3 is provided with third wheel 4；Described third wheel 4 top is engaged with centre wheel 6 by little gear；Described third wheel 4 is engaged with the little gear of second wheel 5 bottom；Described second wheel 5 Engage with escape wheel 8；It is provided with escapement lever 9 between described escape wheel 8 and escapement 7；The movable end of described escapement lever 9 is provided with joins Component 10；Described counterpart 10 is plugged in the furcation of escapement lever 9, and the external gear phase interworking of counterpart 10 and escape wheel 8 Close.

Wherein, described counterpart 10 and escapement lever 9 are interference fit, good stability, are easy to dismount.

During the operation of this specific embodiment, counterpart is coordinated with escapement lever 9, and when producing abrasion, counterpart active is worn, To save escape wheel 8 from damage, and do not interfere with escapement lever 9, improve overall service life.

This specific embodiment reasonable in design, easy to use, motility is good, good stability, weares and teares for single, more Change low cost, long service life.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.This The technical staff of industry, it should be appreciated that this utility model is not restricted to the described embodiments, retouches in above-described embodiment and description That states simply illustrates principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model Also have various changes and modifications, these changes and improvements both fall within the range of claimed this utility model.This practicality is new Type claims scope by appending claims and its equivalent thereof.
