Abstract

The utility model relates to a pointer-type clock time displaying device of world time zone, comprising a dial plate, an hour hand and a minute hand. The utility model is characterized in that the circumference of the dial plate is divided into 24 parts equally; the transmission ratio between the hour hand and the minute hand is 1:24; the disk surface of the dial plate is opened with a window for displaying the time zone and a time zone displaying disk is arranged under the dial plate; an hour hand driving gear is connected with an hour hand beam-barrel which is sleeved with a time zone beam-barrel outside, through a conical gear plate with 24 gears. The time zone displaying disk is fixed on the time zone beam-barrel. The utility model has the advantages that the dial plate still adopts a three-hand form, conforms to the visual habit of people, and the disk surface of the dial plate is simple and clear and the regulation of the time zone is convenient.

Description

Pointer-type world time zone timepiece time display apparatus

Technical field

The utility model belongs to a kind of timing display device, particularly a kind of pointer-type world time zone timepiece time display apparatus that can show certain time zone local standard time of the world separately.

Background technology

The people in ancient times comes computing time by the position of the sun, for example " corona "; The people in modern age has invented machinery or electronic installation to represent local time, for example " clock and watch "; And the modern is divided into 24 time zones to the earth, has solved the position of sun of different longitudes and the consistance of local time on the earth.But along with the continuous development of Modern Traffic and communication mode, and there are not clock and watch that are merely able to show very easily zebra time, so this time difference all over the world brings a lot of inconveniences to people again simultaneously.Therefore, a lot of in recent years people are constantly studying and are making the clock and watch that can show zebra time.But make a general survey of in existing market and the open source literature the universal clock that can see, still continue to use the dial plate of existing 12 five equilibriums, adopt two hour hands or pin demonstration for a long time, be the local time that two or more hour hands are indicated different time zone respectively, perhaps adopt two dial plates to show the time of different time zone respectively.Though the universal clock of these several structures can demonstrate the time in the world, owing to dial plate is in a mess, so the inconvenience of watching is not directly perceived.

Summary of the invention

The purpose of this utility model provides and shows clock and watch a kind of novel zebra time, it can overcome existing shortcoming in the prior art, can show the local time that certain is regional separately according to user's selection, make the zebra time of clear display, directly perceived on dial plate.

The purpose of this utility model is achieved in that it comprises dial plate, hour hands and a minute hand, it is characterized in that the dial plate circumference is divided into 24 five equilibriums, ratio of gear between hour hands and the minute hand is 1: 24, at the window that has show-timezone on the card of dial plate and the time zone display panel is housed under dial plate, but the circular cone fluted disc of 24 teeth by a clutch between hour hands driven wheel and the hour hands beam barrel is connected, be set with a time zone beam barrel in the outside of hour hands beam barrel, the time zone display panel is fixed on the beam barrel of time zone.

The utility model has the advantages that: dial plate still adopts three pointer forms, meets people's visual custom, and the card of dial plate is succinct, clear, time zone easy to adjust, and when carrying out the adjustment in time zone, hour hands can obtain synchronous adjustment.

Description of drawings

The utility model is described in more detail below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of dial plate of the present utility model.

Fig. 2 is the utility model structural relation synoptic diagram between each beam barrel under the state when normally walking.

Fig. 3 is the utility model structural relation synoptic diagram between each beam barrel when adjusting in the time zone.

Embodiment

As seen from the figure, the 1st, watchcase is equipped with dial plate 2 in watchcase, and the circumference of dial plate is divided into 24 equal portions, shows one day 24 hours.More directly perceived for showing, be shaped on black pattern at the upper semi-circle of dial plate, show from evening 18 be night up to early 6 o'clock, lower half circle be a white, show from morning 6 be daytime up to late 18 o'clock.Three root pointers that the indication of time still adopts everybody to be accustomed to, i.e. hour hands 3, minute hand 4 and second hand 5.Keep original ratio of gear between second hand and the minute hand, promptly to circle be 60 seconds to second hand, and it is 60 minutes that minute hand circles.Ratio changing between hour hands and the minute hand is 1/24, and promptly to rotate a week be 24 hours to hour hands.Have a display window 6 on the top of dial plate, in order to the title of show-timezone.The title in time zone be indicated in a rotary time zone display panel 9 above, the time zone display panel be installed in dial plate below.Owing to need carry out the adjustment in time zone and the adjustment of time, knob 8 is adjusted in the time zone and the time is adjusted knob 7 so the utility model is provided with.The structure that time is adjusted is same as the prior art.And the structure of time zone adjusting gear as shown in Figures 2 and 3.The upper surface of hour hands driven wheel has the circular cone fluted disc A of 24 teeth, and be fixedly connected with a hour hand gear beam barrel 11, the hour hands beam barrel 12 of fixedlying connected with hour hands is sleeved on the outside of hour hand gear beam barrel, be fixed with the circular cone fluted disc B of 24 teeth in the lower end of hour hands beam barrel, A is meshed with the circular cone fluted disc, be set with time zone beam barrel 13 in the outside of hour hands beam barrel, time zone display panel 9 is fixed on the outside of time zone beam barrel.Second hand axle 14 and minute hand beam barrel 15 are sleeved in the hour hand gear beam barrel successively.

When clock and watch normally showed, the circular cone fluted disc of 24 teeth was meshing with each other, and the hour hands driven wheel drives the hour hands walking by circular cone fluted disc and hour hands beam barrel.And the time zone display panel is owing to there being the spacing of 24 elastic positioning devices, so together do not rotate with the hour hand axle tube.Above-mentioned elastic positioning device is identical with the positioning device structure of date demonstration of the prior art.When needs are adjusted the time zone, circular cone fluted disc A and B are broken away from mutually, at this moment the hour hands beam barrel is in time distinguished beam barrel and drive unit disengaging.Because the scale in 24 time zones is corresponding mutually on dial plate last 24 hour of demonstration and the time zone display panel, so under the qualification of elastic positioning device, hour hands beam barrel and time zone beam barrel rotate synchronously, can accurately adjust to certain selected time zone and local time accurately that mutually should the time zone.

Claims (1)

1, pin type world time zone clock and watch time display apparatus, it comprises dial plate, hour hands and a minute hand, it is characterized in that the dial plate circumference is divided into 24 five equilibriums, ratio of gear between hour hands and the minute hand is 1: 24, at the window that has show-timezone on the card of dial plate and the time zone display panel is housed under dial plate, but the circular cone fluted disc of 24 teeth by a clutch between hour hands driven wheel and the hour hands beam barrel is connected, be set with a time zone beam barrel in the outside of hour hands beam barrel, the time zone display panel is fixed on the beam barrel of time zone.
