The utility model discloses a globe presentation device, it has been add the lamp body and has been used for replacing the sun, shine the sunlight to the earth, so the daytime of the demonstration earth in turn, the change in the time difference and the four seasons, also can be used for strengthening simultaneously light, its magnifying glass of addding makes classmates can see the small character on the globe clearly, and the magnifying glass can reciprocate with elastic moreover, and then can accurately find the position that needs to enlarge the observation, makes the device have more the practicality.
Description
Technical field
The utility model relates to geographical teaching demonstration teaching aid, particularly relates to a kind of terrestrial globe apparatus for demonstrating.
Background technology
In geographical teaching, explanation for macroscopical earth always allows students indigestion, in particular to parts such as the time difference, Four seasons change and earth ' s interior structures, teacher can think that most method is explained for student, and the statement depending language alone is difficult to allow student understand thoroughly; And existing function of globe is single, and on terrestrial globe, word is all very little, is difficult to see clearly, and this just brings certain difficulty to teachers ' teaching.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of terrestrial globe apparatus for demonstrating.
A kind of terrestrial globe apparatus for demonstrating of the present utility model, be made up of ground ball, support shaft and base, described support axle bed is on base, axis body on support shaft embeds the groove at two ends on ground ball axis direction, the base of ball horizontal axis side, ground is fixed with the body of rod, the body of rod is provided with slideway, slideway and connecting rod one end are slidably connected, connecting rod is parallel with ground ball horizontal axis, the head of connecting rod is fixed with magnifier, the top of the body of rod is provided with lamp body, and base is provided with the switch of lamp body.
As further improvement of the utility model, described slideway inside is provided with the identical lug boss in interval, and the trailer card of connecting rod is connected on the lug boss of slideway inside.
As further improvement of the utility model, described connecting rod is greater than the radius of ground ball with the distance of ground ball horizontal axis.
As further improvement of the utility model, described connecting rod is extensible link.
As further improvement of the utility model, described ground ball is made up of two hemisphere, and two mutual snappings of hemisphere, the inside ecto-entad of hemisphere is provided with the earth's crust, earth mantle and the earth's core successively.
A kind of terrestrial globe apparatus for demonstrating of the present utility model, it has been set up lamp body and has been used for replacing the sun, by solar irradiation to the earth, so the daytime of the demonstration earth alternately, the change in the time difference and the four seasons, also can be used for strengthening light simultaneously; Its magnifier set up, make classmates can see small character on terrestrial globe clearly, and magnifier can move up and down with elastic, and then can find the position needing amplifying observation exactly, make device have more practicality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is spheroid cut-open view of the present utility model;
Fig. 3 is body of rod cut-open view of the present utility model.
Embodiment
As shown in Figure 1, a kind of terrestrial globe apparatus for demonstrating of the present utility model, be made up of ground ball 1, support shaft 2 and base 3, described support shaft 2 is made up of pedestal and semi-circular support body, semi-circular support body is fixed on pedestal, the pedestal seat of support shaft 2 is on base 3, the two ends of the annular frame of support shaft 2 are fixed with axis body 4, two ends on the ground direction of principal axis of ground ball 1 are provided with groove, axis body 4 on support shaft 2 embeds in the groove of ground ball 1, makes ground ball 1 can with the axis at two axis body 4 places for axle rotates; The base 3 of ball 1 horizontal axis side, ground is fixed with the body of rod 5, the body of rod 5 is provided with slideway 6, slideway 6 and extensible link 7 one end are slidably connected, it is inner that extensible link 7 is embedded in slideway 6, and extensible link 7 can be slided on slideway 6, slideway 6 inside is provided with the identical lug boss 15(in interval as Fig. 3), when extensible link 7 is wanted to be fixed on certain position, the trailer card of extensible link 7 can be connected on the lug boss 15 of slideway 6 inside, the object of fixing extensible link 7 can be reached; Connecting rod 7 is parallel with ground ball 1 horizontal axis, connecting rod 7 is greater than the radius of ground ball 1 with the distance of ground ball 1 horizontal axis, the head of extensible link 7 is fixed with magnifier 8, and magnifier 8 can realize moving up and down with elastic thus, and then facilitates the use of magnifier; The top of the body of rod 5 is provided with lamp body 9, and the light that lamp body 9 sends can simulated solar irradiation, facilitate teacher explain on classroom daytime alternately, the change in the time difference and the four seasons; Base 3 is provided with the switch 10 of lamp body 9; Ground ball 1 is made up of two hemisphere 11, two hemisphere 11 snapping mutually, the inside ecto-entad of hemisphere 11 is provided with the earth's crust 12, earth mantle 13 and earth's core 14(successively as Fig. 2), when needs explanation earth ' s interior structure, ground ball 1 can be split into two halves, make classmates get more information about the internal structure of the earth.
