Description

A kind of clock movement

Technical field

The utility model relates to the time keeping instrument technical field, relates in particular to a kind of movement that is widely used in the crystal clock clock.

Background technology

Each manufacturer of present technique field introduces and extensively enters the clock that is used for timing of family and public place to the market at present, three-hand type crystal clock particularly, cheap, fashionable, accurate when walking with its product price, and it is very popular, it gives beyond people's clocking capability, give the enjoyment of a kind of aesthetic feeling of people and art simultaneously, enriched people's life.Yet as three-hand type crystal clock clock, but sometimes because of multiple different former thereby cause clock stop clock, walk slow, walk fast or the like qualitative problem, need people in use carry out suitable alloting.As intelligent synchronized clocks, it is widely used in the public place in the certain area coverage such as boats and ships, hotel, office building, airport, station, harbour, for people provide many convenience, and the secondary clock movement of intelligent synchronized clocks also is to adopt existing three-hand type quartz clock movement at present.Because the structure of this movement as shown in Figure 1, its prior art scheme is to constitute the output of stepper motor power and be meshed with second wheel assembly 4 by driving pulley assembly 3 by stepper motor stator 1 and stepping motor rotor 2, second wheel assembly 4 is meshed with dividing wheel assembly 5 through driving pulley assembly 6, divide wheel assembly 5 to be meshed with hour wheel module 7 by driving pulley assembly 8, thereby constitute its whole structure that is in transmission connection, reach and realized its second, branch, the time ratio of gear be 3600: 60: 1 requirement.But because second wheel assembly 4 is meshed by driving pulley assembly 6,8 respectively with dividing wheel assembly 5, hour wheel module 7, make second wheel assembly 4 form interlock mutually with dividing wheel assembly 5, hour wheel module 7, thereby bring following weak point for existing clock: transmission wheel was directly stirred power wheel 8 and is driven branch wheel assembly 5 when the first was dialled pin, dividing wheel assembly 5 to drive second wheel assembly 4 flies to change, not only very easily make second hand become flexible, come off, be difficult to set correctly, and can only dial pin along a direction; Particularly the secondary clock of intelligent synchronized clocks is dialled pin, fast dialling needed 10 minutes in 1 hour, its unnecessary quality problems of as easy as rolling off a log generation, but it is essential dialling pin, as must setting or set back hour hands ahead 1 hour when the intelligent synchronized clocks of using on the naval vessel is crossed over the time zone in oceangoing voyage, and the situation that second hand need not to adjust takes place.It two is in the existing technology of dialling pin, when driving second hand, its second wheel assembly 4 of the process of dialling pin rotates, and in fact the standard time is also ceaselessly walking about, dial in the time that the pin process consumed, second hand and standard time are just caused step property error, also need proofread second hand to the environment that time requirement is very strict, make itself and standard time synchronous.For the existing deficiency of present existing clock movement is those skilled in the art of the present technique are badly in need of solution in the application facet of developing intellectual resource type synchronized clocks problem.

Summary of the invention

The purpose of this utility model is in order to improve above-mentioned the deficiencies in the prior art, and provide a kind of can forward and reverse group of pin, and it is safe and reliable to dial pin, need not to drive that second hand flies to change, quality clock movement more reliably when walking.

When another purpose of the present utility model provides a kind of can chasing after automatically, keep second hand and standard time synchronous, adjust automatically and the master clock also used clock movement of secondary clock of feedback information that is consistent.

The purpose of this utility model is achieved by following technical solution, a kind of clock movement, clamping plate, stepper motor, hour wheel module, branch wheel assembly, second wheel assembly and train were formed before and after it comprised, its special character is that this clock movement comprises by two shared stepping motor rotors of stepper motor stator and constitutes a two-way stepper motor, and its output shaft is meshed with the branch wheel assembly by cannon pinion driving wheel system.

For further realizing the purpose of this utility model, the photoelectric sensor that also is provided with the Photoelectric Detection dish on the hour wheel module described in the technique scheme and matches with it.

The utility model compared with prior art has following characteristics and good effect: the first has been taked to constitute a two-way stepper motor with the technical scheme of two shared stepping motor rotors of stepper motor stator owing to the utility model, and being connected with a joggle by its output shaft and cannon pinion driving wheel system, reach guaranteeing under the condition of ratio of gear to be meshed and be connected with a minute wheel assembly, the other power-driven system of composition one cover replaces in the prior art and divides the wheel assembly kind of drive by the second wheel assembly through the driving pulley assembly drive, thereby make the utlity model has and dial pin time-division wheel assembly and second wheel components apart, unaffected mutually between the two, but forward, oppositely arbitrarily dial pin, the characteristics of group needle speed and reliability have been improved, thereby overcome in the prior art and can only dial pin by forward, drive second hand when dialling pin and rapidly rotate, make second hand loosening easily, unnecessary quality problems such as come off; It two is the enforcement of the technical solution of the utility model, make to dial and have second hand in the pin process still by the characteristics of standard time in operation, second hand quits work with dialling the pin time when having overcome prior art and dialling pin, and there is the step of falling property error with the standard time, the shortcoming that need proofread also, make to the utlity model has that remain and standard time synchronous operation second when dialling pin, need not to carry out the advantage that second hand is adjusted, saved group pin time; It three is the enforcement of the technical solution of the utility model, adopt two cover stepper motors to drive the second wheel assembly respectively and divide wheel assembly, hour wheel module, though increased some parts, improved the manufacturing cost of clock movement, but overcome single step motor drive in the prior art, the shortcoming that movement train load is heavy, it is light to make it have an operating load, the motor output torque is little, the reliable more good effect of quality when movement is walked.It four is that the utility model takes to be provided with the Photoelectric Detection dish and the technical scheme of the photoelectric sensor that matches with it on hour wheel module, make intelligent synchronized clocks movement, by the control circuit in the princip al and subordinate clock system, single-chip microcomputer dispatch control system, make it possess function when chasing after automatically, automatically dial pin and be consistent, the self-operating situation is fed back to the good effect of master clock with the master clock of princip al and subordinate clock system.
