Description

Disc-shape globe clock

The utility model relates to a kind of disc-shape globe clock.

Present clock and watch develop into quartz electronic clock and watch by mechanical clock, and the law in the mechanical clock driving mechanism, escapement and gear mechanism are that the quartz crystal and the ic circuit of electronic watch replaces, and be simple in structure, accurate when walking; But on function, still be confined to the time in a time zone; Be distributed in earth diverse geographic location and using time by the time zone separately of Greenwich mean time regulation; Existing clock and watch then can't be known other regional time of the synchronization world.For example, when the 12 noon of Beijing, the London of Britain is 4:00 AM, and present clock and watch can't demonstrate Britain or other regional synchronization time of the world.

The purpose of this utility model provide a kind of hour hand axle, dial plate by clockwork and be stained with on the south the disc-shape globe clock formed of the disk of center and the world map that makes around the Southern Hemisphere very; Disc-shape globe clock can indicate synchronization time of different regions in the world.

The utility model content, the upper end of the hour hand axle of the clockwork of disc-shape globe clock is provided with disk, the world map that launches round the Southern Hemisphere of center very on the south being stained with above the disk, this world map is by per 15 degree pictures one time zone lines in center very on the south the GMT (Greenwich mean time), totally 24 time zone lines, form 24 time zones, be positioned on the dial plate of disk outer ring and be provided with 0 in the counterclockwise direction, 1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7,8,9,10,11 totally 24 graticules and numerals are loaded on the transparent glass cover on disc-shape globe clock top and are pasted with the dark hyaline membrane of half of bright one side of something.

The utility model advantage, the world map that launches round the Southern Hemisphere of center very on the south being stained with on the disk of the hour hand axle of disc-shape globe clock upper end, on this world map by per 15 degree warps of picture and form 24 time intervals Greenwich mean time; After the time of this area (being the location) was aligned by dial plate graticule and numeral, other various places, world time this moment can read on the dial plate of correspondence, and is directly perceived, convenient, need not convert, the utility model is simple in structure, and is handsome in appearance, has good decoration function.

Description of drawings:

Fig. 1 is signal (analysing and observe) figure of the utility model embodiment.

Fig. 2 is the vertical view of Fig. 1.

Further specify the utility model embodiment below in conjunction with accompanying drawing, on the housing 3 of disc type globe clock clockwork 1 is housed, be provided with the through hole 8 that passes for hour hand axle 2 in the middle of the housing, the hour hand axle upper end is provided with disk 4, center very on the south adhering to above the disk, and the world map 5 that launches round the earth surface in the Southern Hemisphere, this world map is a time zone and draws 24 time zone lines according to per 15 degree of GMT (Greenwich mean time), form interval, 24 time zones, hour hand axle and disk counterclockwise rotate, being provided with dial plate 9 on housing top, is that the center counterclockwise is provided with 24 time zone lines and corresponding time figure equably with through hole 8 on the dial plate: 0,1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7,8,9,10,11 totally 24 numerical value and grooves; Adorn a transparent cloche 7 (or plexiglass tent) above the dial plate, and on cloche, attach the dark hyaline membrane 6 of a half of bright one side of something, the separatrix of this film should be facing to 6 of the morning on the dial plate and late 6 graticules, the time zone of light correspondence is daytime, darker part is night, is example with Beijing, when the 12 noon of Beijing, Beijing in the aforementioned world map should be in the light of aforementioned films, is point at noons 12; Clockwork 1 can adopt existing clockwork, and need be changed a social system, be about to per 12 hours hour hands of used clockwork circle change per 24 hours into and circle, just each hour changeed 15 degree.After the disc type globe clock connects electricity, when Beijing (A) walks to 12 noon that dial plate shows, can see the time in other city, the world or area from disc-shape globe clock, for example Sydney (B) time is 14 points, Washington (C) time is 22 points, and Paris (D) time is 4:00 AM.
