Embodiment

In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.

See also illustrated in figures 1 and 2, this can show the clock of various places time, the indicator that comprises mechanical movement and power supply, the dial plate 2 in the shell 1, shell and be installed on the dial plate 2 and be coupling with movement, wherein, described shell 1 ad-hoc location has a time zone selected marker 3, a swivel eye 4 is installed between shell 1 and the dial plate 2, be evenly distributed with the mark 5 of time zone on the front surface circumference of this swivel eye 4, the mark 5 of this time zone can be time zone mark or city name label, and can be dot mark or embossing; Also have an IC control chip 6 and a micro-step motor 7 that is connected with this IC control chip 6 in the described movement, described indicator comprises hour hands 8 and minute hand 9, be individually fixed on hour hand axle and the minute hand shaft, has gear engagement mechanism between this minute hand shaft and the hour hand axle, described micro-step motor 7 is connected with minute hand shaft by gear engagement mechanism, described IC control chip 6 also is connected with swivel eye contact-making switch 10, time setting switch 11, reset switch 12, described time setting switch 11 is connected with time set button on the shell, and swivel eye contact-making switch 10 all is connected with described swivel eye 4 with reset switch 12.

Moreover, also comprise regularly quarter-bell pin 13 in this indicator, be fixed in regularly on the quarter-bell needle shaft, described IC control chip 6 also is connected with quarter-bell trigger switch 14, and described quarter-bell trigger switch 14 is connected with timing quarter-bell needle shaft, hour hand axle, minute hand shaft by the mechanical gear engaging mechanism; Simultaneously, also have a quarter-bell adjusting knob on the back side of this shell 1, this quarter-bell adjusting knob is connected with timing quarter-bell needle shaft by gear engagement mechanism.

Further be, summer time (DST) switching push button also is installed on the shell of this clock, described IC control chip also is connected with summer time change-over switch 15, and described summer time change-over switch 15 is connected with described summer time switching push button.

Wherein, time zone selected marker 3 is used to refer to the selection of time zone; IC control chip 6 is used for controlling micro-step motor 7, and it has two duties:

(1) under the usual condition, IC control chip 6 is every to send pulse signal to micro-step motor 7, controls the speed motion of minute hand 9 with per minute rotation 6 degree;

(2) after swivel eye 4 rotates to another time zone, IC control chip 6 just can calculate the time difference of two time zones and it is converted is the number of minutes, calculates according to the following equation then, draws the corresponding pulses quantity that should send:

Should send out the number of minutes * per minute minute hand that pulse total quantity=two time zones differ and move the required number of pulses of 6 degree

Send the pulse of above-mentioned respective numbers then to micro-step motor 7, thereby drive minute hand 9 fast rotational to the appropriate location.

Swivel eye contact-making switch 10 just can trigger behind another time zone in suitable distance of each swivel eye 4 rotations; The quarter-bell that the gear engagement mechanism arrival timing quarter-bell pin of quarter-bell trigger switch 14 in movement presets just can trigger during the time, thereby sent ring tone; Micro-step motor 7 just can be finished the rotation of one 180 degree after whenever receiving each pulse signal that IC control chip 6 sends; It is synchronous that reset switch 12 is used for carrying out the time zone; Time setting switch 11 just can the quick rotation minute hand when pressing, and just can stop after the relieving; The effect of summer time (DST) change-over switch 15 is the time of clock system can be switched arbitrarily between the summer time (DST) in conventional time (STD) and indivedual cities, thereby makes IC control chip 6 to carry out the conversion of time zone according to different time systems (STD or DST).

In the middle of reality is used, design of the present utility model is sent a series of control wave by IC control chip 6 to micro-step motor 7 exactly, thereby fast driving minute hand 9 rotates, finally make hour hands 8 rotate to the appropriate location, finish time Fast transforms and demonstration between the different time zone by being attached thereto the gear engagement mechanism that connects.

In the process of user's operation, its operation steps is as follows:

(1) at first load onto battery after, the user at first needs the position alignment with reset flag on the swivel eye 4 and time zone selected marker 3;

(2) this moment, reset switch 12 was pressed, thereby carried out time synchronized;

(3) user is rotated swivel eye 4, makes selected time zone mark aim at time zone selected marker 3;

(4) press time set button and keep, thereby the control time configuration switch triggers, just can make minute hand 9 quick rotation, after it adjusts to accurately the position, release-push;

(5) if regularly quarter-bell pin 13 is installed on the clock, then, regulate the quarter-bell time by the quarter-bell adjusting knob at rotational shell 1 back side.

Motion by above-mentioned direct driving minute hand 9, act on moment of torsion on the hour hands 8 this moment and have only and directly drive 1/60th (1/60) of the moment of torsion that acts under the second hand motion conditions on the hour hands 8 usually, and the moment of torsion on the hour hands 8 when requiring to carry out quarter-bell usually and triggering is much bigger.Problem on this moment of torsion can solve by the program of adjusting IC control chip 6 inside, wherein make pulse width in the quarter-bell trigger process greater than the normal operations process, so just, can reach reasonable effect, and the binding function that this pulse width can be used as IC control chip 6 is selected.

Adopted the clock of above-mentioned shown various places time, owing to adopt the IC control chip 6 of movement inside and the rotation that micro-step motor 7 is directly controlled minute hand shaft, finally finish the adjustment of zones of different time again by the gearing mesh between minute hand shaft and the hour hand axle, make this adjustment process to carry out accurate Calculation according to the time difference of two places, realize that resolution is up to the accurate adjusting of minute level, and operating process is simple and convenient, the time difference that is highly suitable between the city is regulated situation, such as the time for India New Delhi be GMT+5.5, in this case, just can realize the accurate adjusting under the non-whole hourage time difference situation, thereby solved the defective that can't be suitable for this situation in the prior art because direct control clock axle can only carry out whole hour adjusting, reached desirable effect; Moreover, adopt the stable and reliable working performance of this design, applicable surface is comparatively extensive.

In this instructions, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
