Abstract

The utility model relates to a regional time contrast card, which is characterized in that the regional time contrast card is composed of two rotary disk bodies that are hinged with each other through the centers of circles thereof, wherein the periphery of one rotary disk body A is printed with time scales for one day and the periphery of the other rotary disk body B is correspondingly printed with names of regions which are divided according to the longitude. Corresponding time on the rotary disk body A, which is pointed by the position of the name of each region, is the time of the region. The utility model has the advantages of simple manufacturing process, economy and utility, and portability and helps users quickly know the needed time at any time at any place. In addition, the utility model can help students easily and visually master the knowledge of local time and zone time, which is always the learning difficulties for students in science course learning in the secondary school.

Description

Zone time is to picture ID

Technical field

The utility model relates to a kind of area table of comparisons constantly.

Technical background

At present, the known local mode of contrast constantly generally is to contrast by hanging several the clocks according to the good moment of converting simultaneously, as guesthouses for foreign guests, is exactly to allow the passenger obtain ground, each department temporal information in this way.If calculate the corresponding moment of different regions by the relevant calculation mode, that is time-consumingly to make mistakes easily again.

Summary of the invention

In order to overcome the existing local difficulty of contrast constantly, the purpose of this utility model is to provide a kind of zone time to picture ID, this area's time, not only manufacture craft was simple, economical and practical and portable to picture ID, and was convenient to the user and can knows the corresponding moment of different regions fast whenever and wherever possible.

Structure of the present utility model, it is characterized in that it is made up of two rotary cases that are hinged by the center of circle, be printed on one day time scale on the perimembranous of one of them rotary case A, the corresponding regional title of dividing that is printed on the perimembranous of another rotary case B by longitude, the corresponding moment that is this area constantly on the specified rotary case A in title position, each department.During use, the position that can the numerical value of this time of reflection on the rotary case A be gone up reflection this area title to rotary case B according to the time in a certain moment of a certain area earlier, so on rotary case B, the time of other parts of the world, can determine or obtain by the position of regional title.It is characterized in that rotary case A is printed on 360 scale marks on the circumference of its outermost, every scale mark is separated by 1 °.Per 15 scale marks are represented 1 hour respectively, and totally 24 hours, each hourage with 24 o'clock showed respectively on its relevant position.Be printed on three waney donuts on the circumferential part of rotary case B, be printed on longitude on each annulus respectively accordingly, the title of time zone and each representative cities, time zone.Wherein the scale mark of longitude also is divided into 360 scale marks the most inboard, and every scale mark is separated by 1 °, indicates longitude every 15 °, and annotates Shang Dong, west sign E and W.These grooves are corresponding with the time groove on the roundel card.Be printed on longitude in the periphery that nestles up longitude and divide corresponding 24 time zones.Then be printed on representational city, each time zone in the periphery in time zone.

The beneficial effects of the utility model are that manufacture craft is simple, economic, practical, convenient and portable, is convenient to the user and can knows the required time fast whenever and wherever possible.This external middle school gets in the natural sciences study, and the content during about local time zone always is the difficult point that the student learns, and can also help the student easily to grasp this part knowledge intuitively by use of the present utility model.

Embodiment

The utility model is made up of two rotary cases that are hinged by the center of circle, be printed on one day time scale on the perimembranous of one of them rotary case A, the corresponding regional title of dividing that is printed on the perimembranous of another rotary case B by longitude, the corresponding moment that is this area constantly on the specified rotary case A in title position, each department.

Rotary case A is printed on 360 scale marks on the circumference of its outermost, every scale mark is separated by 1 °.Per 15 scale marks are represented 1 hour respectively, and totally 24 hours, each hourage with 24 o'clock showed respectively on its relevant position.

Be printed on three waney donuts on the circumferential part of rotary case B, be printed on longitude on each annulus respectively accordingly, the title of time zone and each representative cities, time zone.Wherein the scale mark of longitude also is divided into 360 scale marks the most inboard, and every scale mark is separated by 1 °, indicates longitude every 15 °, and annotates Shang Dong, west sign E and W.These grooves are corresponding with the time groove on the roundel card.Be printed on longitude in the periphery that nestles up longitude and divide corresponding 24 time zones.Then be printed on representational city, each time zone in the periphery in time zone.

During use, the position that can the numerical value of this time of reflection on the rotary case A be gone up reflection this area title to rotary case B according to the time in a certain moment of a certain area earlier, so on rotary case B, the time of other parts of the world, can determine or obtain by the position of regional title.

Claims

1. a zone time is to picture ID, it is characterized in that it is made up of two rotary cases that are hinged by the center of circle, be printed on one day time scale on the perimembranous of one of them rotary case A, the corresponding regional title of dividing that is printed on the perimembranous of another rotary case B by longitude, the corresponding moment that is this area constantly on the specified rotary case A in title position, each department.

2. zone time according to claim 1 is to picture ID, it is characterized in that rotary case A is printed on 360 scale marks on the circumference of its outermost, every scale mark is separated by 1 °, per 15 scale marks are represented 1 hour respectively, totally 24 hours, each hourage with 24 o'clock showed respectively on its relevant position.

3. zone time according to claim 1 and 2 is to picture ID, it is characterized in that being printed on three waney donuts on the circumferential part of rotary case B, is printed on longitude on each annulus respectively accordingly, the title of time zone and each representative cities, time zone.Wherein the scale mark of longitude is the most inboard, also be divided into 360 scale marks, every scale mark is separated by 1 °, indicate longitude every 15 °, and notes Shang Dong, west sign E and W, these grooves are corresponding with the time scale line on the rotary case A, are printed in the periphery that nestles up longitude with longitude to divide corresponding 24 time zones, then are printed on representational city, each time zone in the periphery in time zone.
