Abstract

The utility model relates to a novel pointer type clock which can display 24 hours and the time of each time zone of the world. The utility model is characterized in that the distribution ratio of the teeth number between gears of hour hands and a minute hand is adjusted, the rotary speed of an hour hand rotating shaft is a half of that of a normal clock, namely that the hour hands rotate one circle to indicate 24 hours, and an hour hand disc composed of more than two hour hands is sheathed on the hour hand rotating shaft, so the concrete time of each time zone can be read on the hour hand disc.

Description

Clock-type

The utility model belongs to the timing field, particularly a kind of pointer clock-type that can show twenty four hours and regions of the world time.

The pointer clock that existing the people of the world uses is to show the time with ten two: 60: 60 as scale, this demonstration can not be expressed the time in one day twenty four hours and each time zone, the world fully, just referring at 8 as display pointer, may be also may be points in evenings eight at 8 in the morning this moment, secondly a table clock or table it only can show its ground time, can not show the world many local time simultaneously.In patent, disclose at present the patent of many universal clocks,, all needed in gear train, to increase the action that mechanism such as gear comes again universal time coordinated, minute hand, must make troubles to processing like this though can reach above-mentioned functions, and the precision that influences timing.

The purpose of this utility model is a kind of clock and watch that can show one day twenty four hours and each time zone time of the world of design on the basis that does not change traditional clockwork.

Task of the present utility model realizes like this, its structure comprises the housing of traditional clock and watch, index dial, gear train and branch, second hand, big or small reduction gearing fixing on the power shaft in the gear train meshes with little tooth of minute hand and hour hands gear wheel respectively, it is characterized in that big, little reduction gearing number of teeth I3, must satisfy I1=24n between I2 and minute pinion number of teeth I4 and the hour hands gear wheel number of teeth I1, I4=I3/I2n, the n value is to satisfy mark or the integer that each number of gears is an integer, on the hour hands Large Gear Shaft During, be with a time dials of forming by two above hour hands, scale is 24 lattice in the time of on the index dial, divides, second, scale was 60 lattice.The utility model is on the basis of existing clock and watch, by transforming the part gear train is the proportioning of the operative gear number of teeth, make the hour hands rotating speed subtract doppio lunghezza di tempo, become around one week of axle and be twenty four hours, dials when changing hour hands simultaneously and being, when each city title is distinguished rule on time and is marked on the dials, this moment universal clock.

Simple in structure, the handling ease of the utility model can be made the twenty four hours clock and watch that show one city, a time zone or distinguish many cities for a long time as required, makes things convenient for the tourist, need not to adjust when striding the time zone hour hands.

Below in conjunction with legend the utility model is described further:

Fig. 1 gear train synoptic diagram;

Fig. 2 dial synoptic diagram;

With reference to Fig. 1, the big or small reduction gearing 3,2 that is fixed on power shaft meshes with minute pinion 4 and hour hands gear wheel 1 respectively, and the number of teeth proportioning between them must satisfy following relation:

I1 is the hour hands gear wheel number of teeth

I2 is the little reduction gearing number of teeth

I3 is the big retarding gear number of teeth

I4 is the minute pinion number of teeth

I1=24n, I4=I3/I2n, n satisfy mark or the integer that each number of teeth is an integer, and the selection of each number of teeth should be considered punctual timing and be convenient to processing that general n is got three groups of number of teeth proportioning the bests at 2 o'clock:

Be I1=48, I2=10, I3=50, I4=10 I1=48, I2=12, I3=60, I4=10 I1=48, I2=10, I3=60, I4=12

With reference to Fig. 2, scale is 24 lattice in the time of on the graduated time ring 5 of dial, the minute, second scale is 60 lattice, two above time dials of forming 6 of hour hands, in this time,, dials 6 was formed with 24 hour hands, and every hour hands correspondence indicates the main cities title in this time zone, the time also be provided with date line 7 on the dials 6, world modified line same meaning in period in this line and the map, dish is provided with minute hand 8 and second hand 9.

Claims (2)

1, a kind of clock-type, the housing that comprises traditional clock and watch, index dial, gear train and branch, second hand, that fixes on the power shaft in the gear train is big, little reduction gearing meshes with minute pinion and hour hands gear wheel respectively, it is characterized in that big, little reduction gearing number of teeth I3, must satisfy I1=24n between I4 and minute pinion number of teeth I4 and hour hands gear wheel number of teeth I1, I4=I3/I2n, the n value is to satisfy mark or the integer that each number of gears is an integer, on the hour hands Large Gear Shaft During, be with a time dials of forming by two above hour hands, scale is 24 lattice in the time of on the index dial, divides, second, scale was 60 lattice.

2, clock-type according to claim 1, dials is provided with a date line when it is characterized in that.
