Abstract
A time zone teaching meter comprises two parts of an external disc and an internal disc, wherein the external is 24 hours system dial, the internal disc is divided into 24 arc sectors in 15 degree, which stands for 24 time zones, each time zone stands a corresponding city, when clockwise rotating the internal disc, the time that the pattern on the internal disc points to the external disc is the local time of the city in the time zone. At the time that the teaching meter makes students know and read time, students directly feel the theoretical accordance of day-night alternation, date change and time zone shift and the arose of time concept, which is the best teaching meter of time zone shift theory in school geographical knowledge, and has simple structure, low cost and is easy to be popularized.
Description
Technical field
The utility model relates to culture and education apparatus technical field, particularly a kind of time zone teaching instrument.
Background technology
The geographical teacher in the vast middle school of China is to student explain world time zone problem the time at present, all be being that the spherical earth is launched into a plane originally, the warp that originally is a circle being launched into straight line coming problem to student explain world time zone, how does explanation alternate round the clock? how new one day begin? how does time define? how convert in the time zone.Which country or which city is in the bad expression in which time zone, can only draw the way that coordinate adopts Dong Jiaxi to subtract point-blank and explain, and is very not directly perceived, student's indigestion, and teacher also is difficult to explanation, causes teaching efficiency poor.
Summary of the invention
The purpose of this utility model is to provide a kind of day and night variation that can make the student experience the whole world intuitively, and the date changes timely position and moves, and can significantly improve the time zone teaching instrument of teaching efficiency.
The purpose of this utility model is achieved by the following scheme: a kind of time zone teaching instrument is made up of outer dish (1) and inner disc (2) two parts, and is all injection molded with poly-third vinyl material.Outer dish (1) center is injected with a central shaft (3), and the edge posts a circle adhesive sticker (4).Equally spaced be carved with 24 figure places such as 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23 on the adhesive sticker.At numeral 6,12,18 other line in morning, flat holiday, the line printed words of losing consciousness of being carved with respectively.Post one deck adhesive sticker (5) on the inner disc (2), whole adhesive sticker disc is divided into 24 circular arc covering of the fans by 15 ° of intervals.Be carved with 0 °, London meridian, O on 24 circular arc covering of the fans successively; E15 °, Paris ,+1; E30 °, Moscow ,+2; E45 °, Riyadh ,+3; E60 °, Abu Dhabi ,+4; E75 °, Islamabad ,+5; E90 °, Dacca ,+6; E105 °, Bangkok ,+7; E120 °, Beijing ,+8; E135 °, Tokyo ,+9; E150 °, Sydney ,+10; E165 °, Honiara ,+11; E180 ° of W, Tarawa, day line, ± 12; W165 °, slave Ku Aluofa ,-11; W150 °, Honolulu ,-10; W135 °, Anchorage ,-9; W120 °, Los Angeles ,-8; W105 °, salt lake city ,-7; W90 °, Chicago ,-6; W75 °, New York ,-5; W60 °, Santiago ,-4; W45 °, Brasilia ,-3; W30 °, Praia ,-2; W15 °, Reykjavik ,-1.Simultaneously, also be carved with a finger-shaped index map on each circular arc covering of the fan.Inner disc and on the adhesive sticker center of circle center pit (6) is arranged, by it inner disc (2) is through on the central shaft (3) of outer dish (1), and the nut by central shaft with inner disc (2) with coil (1) outward and connect together.
The utility model can show and read the time in Beijing time and all time zones, the whole world simultaneously, and international date line (day line), GMT (Greenwich mean time) (0 ° of warp), terminator, flat holiday (12 point) etc., make numerous students when recognizing read time, direct feel is to the day and night variation in the whole world, date is changed the theoretical foundation and the timing definition origin of moving timely position, see that intuitively the earth is in ceaselessly running from West to East, and can see round the clock how alternating, how date changes, how new one day begin, how time defines, and how convert in the time zone.It can be a benchmark with Beijing (Dong8Qu) time, and 15 ° of the every increases of east longitude are promptly whenever striden a time zone and added 1 hour, and half time zone adds half an hour.Otherwise subtract 1 hour or half an hour, thereby read easily the Beijing time in city, place, corresponding time zone.Enter east from 12 time zones, west and 12 time zones (the crossing day line) date will add one day, otherwise then subtract one day.It is the best teaching aid of displacement theory in time zone in the geographical knowledge, and simple in structure, and cost is low, easily popularizes.
Description of drawings
Fig. 1 is the time zone teaching instrument structural representation.
Fig. 2 coils structural representation outward for time zone teaching instrument.
Among the figure, 1 outer dish, 2 inner discs, 3 central shafts, 4,5 adhesive stickers, 6 interior center hole, E represents east longitude, and W represents west longitude, and+1～+ 12 represents the Sector East, and-1～-12 represents the Westbound.
Embodiment
A kind of time zone teaching instrument, it is made up of outer dish (1) and inner disc (2) two major parts, and is all injection molded with poly-third vinyl material.Outer dish (1) is 24 hours scale making dishes, and the center is injected with a central shaft (3), and there is screw thread the end, and outer plate edge posts a circle adhesive sticker (4).Adhesive sticker equally spaced is carved with O, 1 on (4) ... 24 bit digital such as 23 grades, and at numeral 6,12,18 other line in morning, flat holiday, the line printed words of losing consciousness of being carved with respectively.The earth of inner disc (2) representative from seeing above the Antarctic posts one deck adhesive sticker (5), and per 15 ° of delineations is divided into a time zone on it, be divided into 24 time zones.Corresponding city, each time zone, and delineation has through the number of degrees, city name, time zone number and finger-shaped index map respectively.E represents east longitude, and W represents west longitude, and+1～+ 12 represents the time zone, east, the western time zone of-1～-12 representative.There is a center pit (6) at inner disc (2) center, by it inner disc (2) is through on the central shaft (3) of outer dish (1), and by the nut of central shaft inner disc (2) and outer dish (1) is connected together.When inner disc (2) when clockwise rotating, the outer dish time of finger-shaped pattern indication on the inner disc is exactly the city local time in this time zone.When day line forwarded for 23 o'clock to, last time zone (Xi11Qu) arrived zero point on the earth, and at this moment the whole world all is the same date.Which time zone forwards zero point to, the daystart that time zone is new.6 and 18 is the terminator of generally acknowledging in the world, and inner disc turns over 6 expressions and enters daytime, turns over 18 expressions and enters night.In the time of 12, the sun is the flat holiday of stipulating in the world in the top of the earth.
