The utility model content

The purpose of this utility model will provide a kind of Chronograph timepiece that both can be used as exactly, can be used as the global calculagraph that the teaching aid instrument uses again, to satisfy the different use needs of people.

The utility model is achieved in that this global calculagraph is to be provided with twenty-four theory tabulation dish in the watchcase outer ring, interior card is ten two o'clock tabulation dishes, accompany rotating annular time zone disc between two dial plates, clock and watch pointer and driving mechanism join, be covered with the cover in morning and evening semicircular, that color is dark slightly on twenty-four theory tabulation dish, the straight line that covers morning and evening is by " 6:00 " on the twenty-four theory tabulation dish and " 18:00 ".

Adopt this structure, straight line on the morning and evening cover just corresponding the notion of " circle in morning and evening " in the global timing teaching, be the boundary promptly with this straight line, its top in the cover zone pairing time zone be the moment on daytime, morning and evening is covered that pairing time zone then is the moment in evening in the overlay area in the straight line below.Cover with dark cover so visually, can represent intuitively that this time zone is to be among night.If " 24:00 " on morning and evening cover on from the center of circle to twenty-four theory tabulation dish draws bar straight line or broken line, notion that promptly can this expression " international date line ".Therefore, use the utility model calculagraph, can not only see the correct time in each time zone, the whole world, and can indicate this time zone visually and be in daytime or night, can allow the user more clearly understand the correct time in each time zone and situation round the clock thus easily, and can make people understand and grasp some abstract concepts relatively in relevant " global timing " teaching exactly.

The utility model can also be realized like this: the inner ring edge at annular time zone disc is fixed with guard.Guard can be to be shaped on footpath parallel and continental platform outline line at the transparent cover subscript.Also can be to be connected the netting twine cover body made from the continental platform outline line by the footpath parallel.Adopt the clock and watch of this structure, on the card of global calculagraph, can imitate and demonstrate out the replacement evolving state in each time zone in the earth rotation process exactly intuitively, be more convenient for the student to the study and the grasp of related notion in " global timing " teaching, and the classroom instruction that can make the teacher is more directly perceived, vivider, and the interest of teaching and activity all can increase significantly.
