Abstract

The utility model relates to a pointer type synchronous globe clock. Reading digits of 24 hours or reading digits of 12 hours is marked on a clock disc of the pointer type synchronous globe clock; a master hour hand of the pointer type synchronous globe clock is a disc-shaped master hour hand, and 24 or 12 sub hour hands are arranged on the master hour. The master hour hand and the sub hour hands synchronously rotate, and a minute hand and a second hand are shared by the sub hour hands; representative time zone numbers or place names are respectively arranged on the point of each sub hour hand positioned on the master hour hand. The pointer type synchronous globe clock can simultaneously display the standard time of all time zones of the world, and is suitable for occasions, such as guesthouses, airports, etc.

Description

Synchronous globe clock

The application relates to a kind of pointer time clock table class, the synchronous globe clock technology of especially a kind of pointer-type.

The earth is gyrating, and various places see that the time of sunrise has nothing in common with each other.For the convenience of traffic, communication, determine in the world the earth is divided into 24 time zones, arbitrary two adjacent time zones, time zone in the east always differed one hour than the time zone in west.

Existing pointer clock can only reflect the time in a certain time zone, can not reflect the time in all other time zones simultaneously, and this brings inconvenience to striding time zone work travelling.

The purpose of this utility model is to disclose a kind of synchronous globe clock of pointer-type that can show the time of each time zone, the world, each department simultaneously.

The division of world time zone is standard with the first meridian.From west longitude is the zero zone to 7.5 ° of east longitudes (longitude is spaced apart 15 °) for 7.5 °.From two borders in zero zone respectively eastwards and westwards, every 15 ° of standardized time zones of longitude, thing respectively marks 12 time zones, and 12 time zones, east coincide with 12 time zones, west, the whole world is divided into 24 time zones altogether, and each time zone is all with local mean solar time of central meridian during as the standard in this time zone.One week of earth rotation be one 24 hours round the clock, therefore, one hour standard time difference in every adjacent time zone, along with earth rotation, the standard time in 24 time zones, the standard time difference in adjacent two time zones was always one hour also in synchronous variation.

According to above-mentioned synchronized relation, the application proposes following technical scheme: globe clock is by the dial plate in cycle and the hour hands that rotate relative to dial plate between an individual now synchronously, minute hand, the compositions such as driving mechanism of second hand and pointer, different is described hour hands are one can comprehensive sensing in 360 ° of scopes the female hour hands of disc type, the central shaft and the minute hand of female hour hands, second hand axle is same axle center, but the angular velocity difference of each pointer rotation, carry the period of the day from 11 p.m. to 1 a.m pin that points to different azimuth at least more than three on these mother's hour hands, period of the day from 11 p.m. to 1 a.m pin and female hour hands are structure as a whole and synchronous operation.Here different period of the day from 11 p.m. to 1 a.m pins are represented the time of world's different time zone, therefore, can show the time of different time zone simultaneously on a clock face.

Above-mentioned design has two kinds of optimum implementation.

Scheme one, the dial plate of synchronous globe clock, 24 small time takings are arranged, represent one of one week of earth rotation time round the clock, this moment, female hour hands were that an angular velocity of relative dial plate rotation is identical with rotational-angular velocity of the earth with the center, female hour hands can be divided into 24 little fan-shaped, represent 24 time zones of the different longitudes of same latitude, each the time district center stretch out sub-hour hands, this period of the day from 11 p.m. to 1 a.m pin and female hour hands synchronous operation, these structure clock and watch can show the standard time of world's different time zone simultaneously, minute hand in the table and second hand still respectively are one, see that according to looking conveniently the relative dial plate with second hand of minute hand circles and can be respectively 60 minutes, 60 seconds or 120 minutes, 120 seconds.

Scheme two, on the dial plate of globe clock 12 small time takings are arranged synchronously, be 12 hours pointer watch dials commonly used in the reality, this moment female hour hands can be divided into 12 little fan-shaped, sub-hour hands are stretched out at each little fan-shaped center, period of the day from 11 p.m. to 1 a.m pin and female hour hands synchronous operation, each period of the day from 11 p.m. to 1 a.m pin is represented the time zone standard time in two 12 time zones that are separated by here, and the time difference in two time zones of representative also is 12 hours.Here minute hand and second hand still are one, and its relative dial plate rotates a circle and is respectively 60 minutes, 60 seconds, and the analog timepiece of this structure can show the standard time of world's different time zone simultaneously.

Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Fig. 1 is the globe clock of 24 hours readings.

Fig. 2 is the globe clock of 12 hours readings.

Referring to Fig. 1,24 hours readings are arranged on the dial plate 1, discoid female hour hands 2 be divided into 24 little fan-shaped, each is little carries sub-hour hands 3 on fan-shaped, carry 24 sub-hour hands altogether, these 24 sub-hour hands can be represented tellurian 24 time zones, and period of the day from 11 p.m. to 1 a.m pin and female hour hands are around central shaft 5 and rotational-angular velocity of the earth synchronous operation, minute hand 4 also rotates around central shaft 5 with second hand 6, for each period of the day from 11 p.m. to 1 a.m pin shared.This clock can show the standard time in each time zone, the world simultaneously in the scope at 24 hours.

Referring to 12 hours readings are arranged on Fig. 2 dial plate 1, female hour hands 2 be divided into 12 little fan-shaped, each is little carries sub-hour hands 3 on fan-shaped, each period of the day from 11 p.m. to 1 a.m pin is represented the standard time in two time zones in 12 time zones that are separated by on the earth, see for the ease of looking, fan-shaped suitable position respectively hangs a small tenon board 4 at each period of the day from 11 p.m. to 1 a.m pin place, this label rotates with female hour hands and remains vertical orientations, vertically downward promptly, female hour hands 2 carry period of the day from 11 p.m. to 1 a.m pin 3 and small tenon board 4, with central shaft 6 is the center of circle, dial plate rotation relatively, and minute hand 5 and second hand 7 are that each period of the day from 11 p.m. to 1 a.m pin is shared.

Above-mentioned two kinds of pointer globe clocks can show the standard time in time zone all over the world simultaneously, are applicable to places uses such as hotel, airport.

See that in order to look conveniently the period of the day from 11 p.m. to 1 a.m pin number of female hour hands of above-mentioned two kinds of tables can only show the time zone at world's major cities place, and omits the period of the day from 11 p.m. to 1 a.m pin in other time zone.
