Description

The science and education terrestrial globe

Technical field

The utility model relates to education or demonstration equipment, be a kind of demonstration, instructional function that had both possessed terrestrial globe, can intuitively show the concrete running orbit of boats and ships, the corresponding initial heading of aircraft or the relative destination, angle of starting and the science and education terrestrial globe in relative target range, position and sun set/raise time and orientation again.

Background technology

Traditional terrestrial globe is installed on the support by the earth model of drawing contents such as ocean, land, river, mountain range, warp and weft in the above and constitutes.Can use for teaching and military going up.And in practical experience of life and Popular Science Education, need people to be had gained some understanding in time, orientation that initial heading, route and the sun of ship's navigation and aircraft flight goes out, do not have.Popularizing and propaganda and education's activity of relevant knowledge generally can only help people's study and understand corresponding knowledge by relevant map in the past, and not directly perceived by the explanation of map, and the course line and the often distortion of flight track of sign, caused knowledge to mislead.For addressing the above problem, the applicant's application number is a patented claim formerly of 02203657.1, a kind of Astronomical card is provided, it by a chassis and a transparent face being assembled together through central rotating shaft and be fixed on the face and the steel wire of configuration activities bead constitute, the time that constitutes along branches such as dish weeks is set on its chassis, latitude numerical scale line and the latitude line that is distributed in the card, meridian and longitude boost line are provided with the orientation that constitutes along branches such as dish weeks on transparent face, height number scale and the altitude line that is distributed in the card, position line and orientation boost line.Can be used for intuitively showing boats and ships, aircraft initial heading, concrete navigation route and relative target range, position and sun set/raise time, orientation, help people's understanding and study navigation, aviation, geography, astronomic knowledge.But because it is a planar products, the demonstration shortcoming stereoscopic sensation of related content.

Summary of the invention

The purpose of this utility model is by the solid image improvement to Astronomical card, and combines with traditional terrestrial globe, and a kind of science and education terrestrial globe is provided.It had both possessed demonstration, the instructional function of terrestrial globe, but the demonstration boats and ships directly perceived of solid imageization, the corresponding initial heading of aircraft or the angle of starting, the relatively concrete running orbit of destination and time, the orientation of relative target range, position and sunrise sunset again, thereby be more suitable for being used for the popular understanding intuitively of people and studying the geography, astronomic knowledge.

The technical scheme that realizes above-mentioned purpose is: a kind of science and education terrestrial globe, it includes bracing frame and the terrestrial globe spherical shell of being made up of semi-circular ring and base, at terrestrial globe spherical shell upper edge equatorial line all caulking grooves of one ring are set, match with this caulking groove to be respectively arranged with the terrestrial globe spherical shell is installed in bulb apical axis on the bracing frame in two upper ends of bracing frame, be hinged at the two ends, outside of terrestrial globe spherical shell and apical axis and be equipped with the annulus that vernier is set above, place same plane to be fixed with the planar rings of a global shell in the upper end of bracing frame with apical axis, on planar rings, be equipped with first cover of a spherical shell of forming by position line bar and lower end abutment ring, cover equator thing point at two ends, outside and first of first cover and be hinged and be equipped with the semicircular ring that vernier is set above.

The utility model has on the terrestrial globe of geographic data, set up the planar rings that to represent the true horizon plane, on its ring, accurately mark 0-360 ° of azimuth scale, and by with the cooperating of annulus that is provided with removable vernier, can accurately measure the check geographic position, highly, distance and expression great circle bearing line, the space flight track, check ecliptic track, declination variation etc., utilization covers in first cover of spherical shell that but horizontal direction is rotated on the terrestrial globe spherical shell, with the cooperating of semicircular ring that is equipped with vernier, can understand intuitively that the days are long and the nights short all over the world, polar day phenomenon at polar night, the demonstration different latitude is same date sunrise sunset orientation not, time, the time zone time difference.Can be widely used in fields such as Popular Science Education, military affairs, meteorology and navigation, aviation, construction work.

Description of drawings

Accompanying drawing is this science and education terrestrial globe structural representation.

Embodiment

In conjunction with the accompanying drawings embodiment of the present utility model is described.

Provide as accompanying drawing, this science and education terrestrial globe has a bracing frame 1 and a terrestrial globe spherical shell 2 of being made up of lower half circle ring body and the base that is connected in the center, lower end.Be provided with the caulking groove in global one week of shell at terrestrial globe spherical shell 2 upper edge equatorial lines, two upper ends that match with this caulking groove at bracing frame 1 are respectively arranged with the bulb apical axis, this apical axis can be one-body molded with bracing frame, also can be fixed on the bracing frame upper end by the mode of installing after the moulding.The bulb end of its apical axis embeds in the caulking groove on the spherical shell, the terrestrial globe spherical shell is installed on the bracing frame, and can to make the terrestrial globe spherical shell is the vertical rotation of rotating shaft with the apical axis and be that the strong point horizontally rotates with the apical axis.Be equipped with the annulus 3 that is coated with vernier above in the outside of terrestrial globe spherical shell 2, the summit, both sides and the apical axis of this annulus are hinged, and making it can apical axis be that rotating shaft is rotated relative to spherical shell.Be in same plane is fixed with a ring terrestrial globe spherical shell in the upper end of bracing frame 1 planar rings 4 with apical axis, this has figure timberlines such as 0-360 ° of azimuth scale line and tangential movement direction, tangent line universe direction, vertical the earth's core direction above planar rings.Be provided with first cover 5 of terrestrial globe spherical shell of being made up of position line bar and lower loop on planar rings, this first cover can adopt the plastic material moulding, and also the available metal line is by bending welding fabrication.The lower end of its first cover contacts with the upper surface of planar rings, and chimeric limit is set, and makes first cover do to horizontally rotate on planar rings, and limits moving horizontally of its relative spherical shell.Outside at first cover 5 is equipped with the semicircular ring 6 that installs vernier above, and the two ends of this semicircular ring are hinged with the thing point that second covers relative equator, and the contact that can be hinged is that rotating shaft is rotated relative to first cover.

The combination of terrestrial globe spherical shell of the present utility model and bracing frame also can be adopted and embed ring or bearing-type fit.

When the utility model uses, the box colour picture, graph card and the icon that utilize configuration in addition help people's understanding and study navigation, aviation, geography, astronomic knowledge as traffic direction, orientation and locus models such as Demonstrator aircraft, steamer, rocket, airship, satellite, the sun.
