Abstract

The utility model discloses a pointer type clock, which is composed of a core, an index dial and a watch case. In the core, an hour wheel shaft is sleeved on a minute wheel shaft; a minute-pinion is provided at one side which is composed of an upper and a lower in-line gear; the minute wheel is meshed with the lower gear, and the hour wheel is meshed with the upper gear; a minute hand and an hour hand are respectively installed on the minute wheel shaft and the hour wheel shaft. The transmission ratio of the minute wheel and the hour wheel is 24, and the time scale or number on the index dial is 0 to 24.A driving device will drive the minute wheel and the hour wheel to respectively drive the minute hand and the hour hand to rotate on the index dial; the minute hand will rotate for 24 cycles in a day, and the hour will rotate for one cycle, indicating the twenty-four system time.

Description

Analog timepiece

The utility model relates to the daily timing analog timepiece of making transmission component with gear.

Analog timepiece of the prior art (hereinafter to be referred as clock and watch) comprises mechanical clock, quartz clock etc., is made of three big parts such as movement, dial plate, watchcases.Minute wheel in the movement, back gear, hour wheel mesh successively, the ratio of gear of minute wheel and hour wheel is 12, drive unit driving minute wheel, hour wheel drive minute hand respectively, hour hands rotate on dial plate, the scale of dial plate is 0～12, minute hand rotated for 12 weeks, and hour hands rotated for 1 week, indicated 12 hours, 1 day (mean solar day), hour hands rotated for 2 weeks, indicated 24 hours.This kind clock and watch are that 0 to 24 o'clock chronometry avoiding timing error to adopt is very inconvenient for departments such as post and telecommunications, communications and transportation.Do not have 12 later time numbers on the dial plate, the time number greater than 12 needs to add several drawing by 12.Though so besides clock and watch were divided into two sections with 24 hours, can not dividing from dial plate is the morning or afternoon.The various multi-functional timing clock of putting down in writing in the patent documentation, though have graduated time ring is divided into 24 five equilibriums, resemble application number and be 95203999 ball-type world clock, rack-mount, do not have the every minute and second device again, obviously be not suitable for daily timing.

The purpose of this utility model provides a kind of clock and watch, 1 week of rotation, 1 day (mean solar day) of hour hands, indicate 24 hours (mean solar hour), and be convenient to adopt 0 to 24 o'clock chronometry.

The purpose of this utility model is achieved in that the number of teeth and the modulus of change minute wheel, back gear and hour wheel, and the ratio of gear that makes minute wheel and hour wheel is 24, rotates 12 all hour hands by original minute hand and rotates and change into minute hand 1 week and rotate 24 all hour hands and rotated for 1 week.Correspondingly, dial plate increases a scale or change numeral, scale or numeral when becoming 24 between scale or numeral per two in the time of existing 12.By following and left, last, right, return bottom, represent 0,6,12,18,24 (0), 1 week indications 0～24 hour respectively; Divide (second) order of representation of [(second) is suitable for second hand, down with] identical therewith, be followed successively by 0,15,30,45,60 (0), 1 all indications 0～60 minute (second).(mean solar day) minute hand rotated for 24 weeks on dial plate in such 1 day, and hour hands rotated for 1 week, indicate the corresponding twenty four hours system time the time, branch (second) value.

The utility model is just changed the number of teeth and the modulus of the operative gear of existing clock and watch, increases a scale between the scale or change respective digital when per two of dial plate, and technology is simple, thereby the purpose of this utility model realizes easily.Such clock and watch are fit to adopt 0 to 24 o'clock chronometry; Be easy to distinguish morning and afternoon; The clock and watch of different time zone are put together, also can reflect its time difference (during the band calendar, no matter two time zones at a distance of how far, can both be found out the time difference in two time zones any time) preferably.

The utility model is described in further detail below in conjunction with drawings and embodiments.

Fig. 1 is the front view of a kind of embodiment of the present utility model.

Fig. 2 is the synoptic diagram that minute wheel, back gear, hour wheel mesh successively.

The utility model is made of three big parts such as movement, dial plate, watchcases.Fig. 1 is that dial plate 1 is installed in the front view (the movement part is not drawn) on the watchcase 2, dial plate 1 is with circumference from below a bit, be divided into 24 equal portions, scale during delineation, begin the delineation of 60 equal portions from same point and divide (second) scale,, return bottom from following and left, last, right, represent 24 hours, represent 60 minutes (second).Also can with the time graduated scale on 0～24 even number or only put on 6,12,18,24 4 numbers respectively in left, up, right, down, dial plate 1 also can only be divided into 24 equal portions, with the time scale double as branch (second) scale, the mark methods are the same.Dial plate 1 also can only mark 0～24 even number express time in the corresponding point of 24 equal portions.In order to be convenient to distinguish at minute hand 6, when hour hands 7 close on, the hour hands 7 of these clock and watch are green, and minute hand 6 is other color.

Fig. 2 is the synoptic diagram that minute wheel 3, back gear 4, the hour wheel 5 in the movement meshes successively, and hour wheel 5 axle sleeves are (not detailed among the figure) on 3 of minute wheels.Back gear 4 is in the one side, is by two parts that in-line gears constitute up and down, minute wheel 3 and its underpart gearing mesh, and hour wheel 5 and its upper gear engagement, minute hand 6, hour hands 7 are positioned on 3 of minute wheels respectively and 5 of hour wheels go up (not drawing among the figure).Minute wheel 3 is 14 teeth, and back gear 4 bottoms are 56 teeth, and top is 10 teeth, and hour wheel 5 is 60 teeth, and minute wheel 3 is 24 with the ratio of gear of hour wheel 5.When minute wheel 3 changeed for 24 weeks, back gear 4 changeed for 6 weeks, and hour wheel 5 changeed for 1 weeks that (number of teeth of minute wheel 3, back gear 4, hour wheel 5, modulus after changing, have handsetting mechanism, number of teeth of its relevant gear, modulus are done necessary the adjustment; Its relevant member that has the mechanism of giving the correct time is done necessary the adjustment).

Drive unit in the movement orders about minute wheel 3, back gear 4, hour wheel 5 rotations, minute wheel 3, hour wheel 5 drive minute hand 6, hour hands 7 respectively and rotate on dial plate 1, because minute wheel 3 is 24 with the ratio of gear of hour wheel 5,6 24 weeks of rotation of minute hand, 1 day (mean solar day), hour hands 71 weeks of rotation, just on dial plate 1, indicate the corresponding twenty four hours system time the time, branch, (second) value.

Figure 1 shows that 18:30:55.

Watchcase 2 can be difformity.
