Abstract

The utility model provides a watch with 24 hour indication whose hour hand only walks one circle within one day, belonging to daily supplies watch class. In the indicating hand family and turning family of the analog-type watch, the specific value of the number between the minute cog-tooth and the hour cog-tooth is altered, enabling the hour hand to only rotate one circle within one day. Via 24 Arabic numbers responding to travel time of the hour hand in the circular disc dial plate, the instantaneous true time value sometime one day is spotted apparently. The utility model is suitable to all situations requiring timing, to be used visually, to provide very large convenience for people's life, learning and work, so as to improve the work efficiency of people and social benefit.

Description

24 hours indication clock and watch

Affiliated technical field

The utility model relates to a kind of clock and watch that are marked with indication in 24 hours at clock dial, dial plate.

Background technology

At present, no matter be wall clock, desk clock, mechanical clock, electronic clock, it all is indication in 12 hours that various wrist-watches have only the clock and watch of band indicator, a cycle is 24 hours, this is just as the clock and watch of the measuring apparatus of time, twice same numeral appearred in one day, if do not see that darkness is still white, just do not know be in one day which constantly, yet on TV, in the airport lounge of airport, at the train station in the waiting room, all to distinguish the time in one day 24 hours, people are the timetable of 12 later 13 o'clock to 24 o'clock (0 points) at noon, often just what time say afternoon greater than after deducting 12 hours in 12 hours the number and pondering with the mental arithmetic method, because clock and watch clock dial, also do not indicate on the dial plate from 13 scales up to 24 (0) time and represent that Here it is, and present clock and watch bring very not directly perceived to people on expression problem constantly, very inconvenient, pretty troublesome.

Summary of the invention

For overcome time indication on the former clock and watch directly perceived, bring very inconvenient defective to people, provide a kind of clock dial, dial plate to be marked with the per hour true digital 24 hours indication clock and watch of one day 24 hours period the inside to entire society, make people no matter night by day, one sees the indication of hour hands on the dial plate, just see draw in one day which constantly, because the indication of its time is directly perceived, clear and definite, the life that is convenient for people to, work, study.

The technical scheme that its technical matters that solves the utility model adopts is: be marked with in one day 24 hours per 1 hour true numeral at its clock dial, dial plate, clock dial, dial plate inboard (center of circle side) at former 12 hours indication clock and watch is carved with 24 and divides big lattice equally for this reason, and with 24 corresponding 24 arabic numeral of lattice, represent intraday certain time true value constantly.Still be that original speed is constant during the walking of the second hand in minute hand system, minute hand, during the walking of hour hands than original slow half, hour hands per hour can be walked 30 ° originally in other words, made to walk 15 ° now into; , must change the number of teeth of dividing tooth axle, minute wheel, hour wheel in power train, the number of teeth of two pairs of gears of minute wheel → hour wheel has fixing gear ratio value 1/12 to make 1/24 into for this reason.As for Watch dail plate, if original 12 arabic numeral are made into 24 numerals, number of words distributes too close, sees that table may not see quickly, can only mark the even number numeral like this on dial plate, and the distribution density with original is the same like this.

The beneficial effects of the utility model are, if all clock and watch are all made with indication in 24 hours in the world, will bring quite intuitively, convenient to everyone, thereby improve people's life, study, the efficient of work greatly, its social benefit can't be calculated with money.

Description of drawings

Embodiment below in conjunction with accompanying drawing and pointer quartz table further specifies the utility model.

Fig. 1 is pointer quartz table power train of the present utility model, minute hand system principle schematic.

Fig. 2 is pointer clock and watch indication in 24 hours clock dial figure.

Fig. 3 is 24 hours indication dial plates of pointer clock and watch figure.

In the drawings, rotor part (0) drives power wheel parts (1), and the meshing second wheel parts of power wheel parts (1) (2), second wheel parts (2) passed through wheel component (3) and are connected to minute wheel sheet (8) with friction fit.When second wheel parts (2) rotate, owing to cross the effect of wheel component (3), minute wheel sheet (8) and minute hand (5) rotate, and have a fixing gear ratio value to be 1/60 here between second pinion and the minute wheel, and the rotating ratio between second hand (4) and the minute hand (5) should be 60: 1 like this; Minute wheel sheet (8) drives hour wheel sheet (7) by minute wheel pivot (10) and hour hands (6) rotate, because during the walking of hour hands speed than original slow half, guarantee to divide a tooth number/back gear sheet number of teeth * the stride tooth axle number of teeth/time tooth number=1/24 in other words, promptly when minute hand rotated 360 ° in 1 hour, hour hands 1 hour (big lattice) can only rotate 15 °, and both rotating ratios are 24: 1.Inaccurate and when needing to dial pin when it is found that indicator is walked, by the purpose that realizes dialling pin that contacts of arbor and the castle wheel (11) that couples together with it, back gear sheet (9).Clock dial (12) is the clock dial style of common wall clock, desk clock, and dial plate (13) is for supplying wrist-watch dial plate style.Because the Watch dail plate area is littler than drop dial, its digital distribution density was too close when the full row of number was full in its 24 hours, word is little, see that table does not often see quickly, so now only the even number numeral is write, its digital distribution density does not influence visual determination with originally old-fashioned the same, reach both directly perceived, attractive in appearance again, purpose easily.

Claims (2)

1, a kind of 24 hours indication clock and watch is characterized in that: the hour hands of analog timepiece, only turned around in one day.

2, clock and watch according to claim 1 is characterized in that: in rotation system, minute hand system, and branch tooth number/back gear sheet number of teeth * stride the tooth axle number of teeth/time tooth number=1/24, promptly the rotating ratio of minute hand and hour hands is 24: 1.
