Description
Technical field
The utility model relates to terrestrial globe, particularly a kind of applicable teaching or the terrestrial globe with projecting function as handicraft.
Background technology
Along with the continuous progress of production and processing technical merit, various photovoltaic constantly enter into people's sight line, constantly bring new visual impact.At classroom teaching, also can utilize advanced photoelectric technology to bring excellent lively classroom to student.On geography class, can utilize many pieces of lantern slide that map is presented on curtain, convenient teaching, but these pictures disperse, can not link up and show together, not there is terrestrial globe and there is like that visual experience intuitively, and terrestrial globe small volume, be not suitable for showing all classmates to watch together, the geographical knowledge teaching demonstration of unfavorable use simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is: for the problems referred to above, provide a kind of projectively globe, can utilize the principle of lantern slide that the pattern on terrestrial globe is projected on curtain and shown.
Technical solution of the present utility model is: it comprises that surface establishes figuratum spheroid, the axis of rotation and base, the axis of rotation is fixed on base, spheroid is fixed on the axis of rotation and can freely rotates around it, the part that the described axis of rotation is positioned at described spheroid is provided with two slideways that parallel, between slideway, be provided with projection light source, projection light source is fixed on slideway and in the time applying external force and can be free to slide along slideway by some rollers, described spheroid is by upper cover, lower cover and middle translucent cover form, under be placed on axis hole place and be provided with one section of pipe box being enclosed within on the axis of rotation, the mode that upper cover is connected by tongue and groove respectively with lower cover is connected with translucent cover, the outside of upper cover is provided with the fixture for fixing spheroid, fixture is screwed onto axis of rotation top, described base inside is provided with electric device, electric device is connected with the pipe box of lower cover by gear, can drive spheroid to rotate.
Technique effect of the present utility model is: it has advantages of reasonable in design, both artistic and practical, for convenience detach, easy to maintenance, both handicraft furnishings had been can be used as, also can teaching demonstration, except possessing the basic function of terrestrial globe, also can directly the topomap of globe surface be directly incident upon on curtain and carry out teaching explanation, give full play to student's enthusiasm.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation at the another visual angle of the utility model spherical part.
Embodiment
As illustrated in fig. 1 and 2, it comprises that surface establishes figuratum spheroid 1, the axis of rotation 2 and base 3, the axis of rotation 2 is fixed on base 3, spheroid 1 is fixed on the axis of rotation 2 and can freely rotates around it, the part that the described axis of rotation 2 is positioned at described spheroid 1 is provided with two slideways that parallel 4, between slideway 4, be provided with projection light source 5, projection light source 5 is fixed on slideway 4 and in the time applying external force and can be free to slide along slideway 4 by some rollers 6, described spheroid 1 is by upper cover 7, lower cover 8 and middle translucent cover 9 form, lower cover 8 is provided with one section of pipe box 10 being enclosed within on the axis of rotation in axis hole place, the mode that upper cover 7 is connected by tongue and groove respectively with lower cover 8 is connected with translucent cover 9, the outside of upper cover 7 is provided with the fixture 11 for fixing spheroid 1, fixture 11 is screwed onto the axis of rotation 2 tops, described base 3 inside are provided with electric device 12, electric device 12 is connected with the pipe box 10 of lower cover 8 by gear 13, can drive spheroid 1 to rotate.
Described slideway 4 is right cylinder, and the periphery of described roller 6 is provided with the annular groove adapting with slideway shape.
Described projection light source 5 places are provided with the drive unit rotating for driving rolls 6.
Pattern on translucent cover 9 can adopt colored segment, lines and spelling words intellectual to draw, and lines and word also can adopt the transparent mode of hollow out.The light utilisation point light source that projection light source 5 is sent generates, and utilizes snoot to converge, and recycling lens send, through after translucent cover 9, the pattern on spheroid 1 surface being projected on curtain through amplifying.The axis of rotation 2 at least part below slideway 4 adopts body, to facilitate wire to pass.Except utilizing the mode of landing of above-mentioned electric device controlling projection light source 5, also can adopt the landing of manual mode controlling projection light source 5.The concrete grammar of manually controlling is to connect traction rope in projection light source 5, traction rope is passed by the axis of rotation 2 tops (making body), on the fixture 11 at top, arrange self-locking device (as, utilize spring and the pressing piece with through wires hole, press this pressing piece and can unclamp traction rope, decontrol pressing piece and can lock traction rope by spring) fixed tractive, utilize projection light source 5 to conduct oneself with dignity, unclamp traction rope and can realize descendingly, upwards dragline messenger can be up.Concrete control assembly all can be arranged on the outside surface of base 3, and handled easily and demonstration can certainly further adopt the mode of remote control.
The utility model can conveniently be adjusted the projected position on spheroid, and the pattern of projection is set on episphere or lower semisphere and equatorial positions place, is convenient to very much teaching demonstration.
