Abstract

The utility model discloses a world clock with a map rotary disc, comprising an hour hand (1), a minute hand (2), a second hand (3), a machine core (4), an hour scale plate (5) and an outer case (6). Moreover, the utility model additionally provides a time zone disc (7). The time zone disc (7) is fixed on a time axis of a 24-hour machine core (4) and synchronously run with the hour hand (1). The local time indication of every city in twenty-four time zones at the same moment can be simultaneously read according to the hour numbers of the hour scale plate (5) and positions of the minute hand (2) and the second hand (3) corresponding to place names on a map pf the time zone disc (7). The clock has the advantages of novel design, convenient, hour reading and shapely appearance.

Description

Map rotating disk world clock

The utility model relates to map rotating disk world clock.

Before the utility model is worked it out, ordinary clock mainly by movement, hour hands, minute hand, second hand, the time mechanical and shell form.Its weak point is: can only indicate the time in a certain time zone, and can not indicate the time in other time zone simultaneously.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of world clock that can indicate each time zone time of the whole world intuitively is provided.

The utility model is realized in the following manner: except that have hour hands [1], minute hand [2], second hand [3], movement [4], the time mechanical [5] and shell [6], it is characterized in that time zone disc [7] in addition.Time zone disc [7] be installed in movement [4] the time axle on, with hour hands [1] synchronous operation, according to place name on it and the time mechanical [5], minute hand [2], second hand [3] cooperatively interact and can indicate 24 time zone times all over the world of the whole world simultaneously.

Description of drawings:

Fig. 1 map rotating disk world clock structure front elevation (other view is slightly), and be designated as the specification digest accompanying drawing.

Fig. 2 map rotating disk world clock time zone disc.

Mechanical during Fig. 3 map rotating disk world clock.

Fig. 4 map rotating disk world clock shell.

Be embodiment of the present utility model below:

Fig. 1: 24 o'clock the system movement [4] be fixed in the shell [6], hour hands [1] be in time zone disc [7] outside and together be installed in movement [4] the time axle on, minute hand [2], second hand [3] are contained in respectively on the minute, second needle shaft of movement [4], the time mechanical [5] be positioned at shell [6].

Hour hands [1] pilot clock makes land used position during the local time, and minute hand [2], second hand [3] are indicated identical branch position, each time zone and second position; The position of the position of mechanical [5] and minute hand [2], second hand [3] when corresponding according to time zone, place, name of a city sector opening direction is in the time of can reading at that time time of this city, the minute, second indication.

Fig. 2: time zone disc [7] is a thin rounded flakes, crosses the center of circle and draws straight line whole wafer is divided into 24 sectors, and the polar coordinates projection world map of center deployment very on the south printing on it, and claim with Chinese title and the time zone name that marks a plurality of cities, the world significantly; The similar circular hole of shaft diameter when the disk center is carved with an aperture and movement [4].

Fig. 3: the time mechanical [5] go up with bigger font and equidistantly printing 0,1,2,3 ..., 22,23 totally 24 arabic numeral make numbers constantly, be printed on 0,5 with less font, 10 at moment number with interior one moment of interval number, 50,55 totally 12 numerals carve number as minute, second, minute, second is carved number place radius of a circle and is a bit larger tham time zone disc [7] outer rim radius.

Fig. 4: shell [6] a circular glass sheet at the positive face shield of clock, and this sheet one side of something with light blue.During installation, when the painted straight border of crossing the center of circle is positioned at just directly over the moment several 6 of mechanical [5] and 18 the middle bisector, it is several 19,20,21 that painted areas covers the moment fully ..., 3,4,5 one side of living in represent that it is among " night " in each time zone down; Under painted areas not, it then is " daytime " on one side.

The utility model available metal or nonmetallic materials are made; Movement [4] can be machinery, electronic or quartzy; Place name on the time zone disc [7] can also can be indicated the time zone title with any or kinds of words mark.

The utility model has the advantages that: can indicate simultaneously the whole world 24 time zones a plurality of world big and medium-sized cities local time, straight when reading It is convenient, simple in structure to see, beautiful design.

Claims

1, map rotating disk world clock is characterized in that: mainly by hour hands [1], minute hand [2], second hand [3], movement [4], the time mechanical [5], shell [6] and time zone disc [7] form.

2, map rotating disk world clock according to claim 1 is characterized in that: movement [4] is 24 o'clock system movements; The time mechanical [5] constantly number place radius of a circle is bigger slightly than time zone disc [7] outer rim radius, be printed on two number of turns words on it, the outer ring is printing 0,1,2,3 with bigger font ..., 22,23 totally 24 numerals as numbers constantly; Inner ring is printing 0,5,10 with less font ..., 50,55 totally 12 numerals carve number as minute, second.

3, map rotating disk world clock according to claim 1, it is characterized in that: shell [6] is covering a glass at the positive place of clock, half water white transparency of glass, second half also transparent but with light color, make during installation the bag zone boundary when just being positioned at mechanical [5] constantly number be 6 and 18 horizontal bisectors directly over, painted areas covers the moment several 19 fully, 20,, 4,5 on one side; Time zone disc [7] map is positioned at water white transparency district part, and the corresponding area of expression, city were " daytime " at that time, and the regional city that is positioned under the colour attaching area then is " night ".
