Abstract
The utility model relates to a gas-filled terrestrial globe. Polyethylene film pieces having same shapes are stuck and welded into a sealed sphere; the polar region position of the terrestrial globe is provided with an air charging port with two lugs, and a root is frustum-shaped. The utility model has the advantages of convenience for carrying, convenient operation and low cost. The gas-filled terrestrial globe can be the teaching aid and a toy and can generate the beneficial effect of pleased teaching.
Description
The utility model relates to a kind of teaching aid, is a kind of inflatable terrestrial globe specifically.
Therefore terrestrial globe lifelike image ground has reproduced the celestial body of human survival, becomes a kind of education, particularly in, requisite teaching aid in the primary school education, it is for the exploitation children's intelligence, studying the geography, history benefits.But the terrestrial globe of Xiao Shouing is not in the market recognized to be made by which kind of material and is all had a kind of inevitable defective, promptly is that volume is not collapsible, and therefore, this terrestrial globe carries very inconvenience.Generally on the classroom, on teacher's dais, put a bigger terrestrial globe often, but the student from far away, can not achieve the goal.Now commercially available in addition terrestrial globe volume is less, can not express content more completely, but bigger terrestrial globe price is too high again, is unfavorable for promoting.
The purpose of this utility model is that to overcome prior art not enough and a kind of inflatable terrestrial globe is provided, and when not using, the terrestrial globe volumetric contraction can be easy to carry.
Another purpose of the present utility model is the diameter that increases terrestrial globe under the condition that reduces cost, to increase its surface area.
The purpose of this utility model is achieved in that by the identical polyethylene film weldbonding face of shape, forms the spheroid of a sealing, and each bar weldbonding seam is positioned on the warp of terrestrial globe; Be provided with an inflation inlet on position, terrestrial globe polar region, have two hangers on this inflation inlet, the root of inflation inlet is frustum, has end socket respectively on position, ground, the two poles of the earth.
The accompanying drawing drawing is described as follows:
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2, Fig. 3 are the utility model embodiment 1 gas injection port structure synoptic diagram.
Fig. 4 is the utility model embodiment 2 structural representations.
Describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 as can be seen, it is spherical that the utility model is, it is formed by six polyethylene film sheet 1 weldbondings, this diaphragm 1 is jujube nuclear shape, and six plate shapes are identical, is printed on the figure of terrestrial globe sixth on every.With the synthetic spheroidite of six diaphragms 1 weldbonding successively, each bar weldbonding seam 2 is positioned on a certain the warp of terrestrial globe just, does not destroy the distribution of warp on the globe surface, makes entirely globe clear clearly demarcated through, parallel.Weldbonding has two circular heads respectively in position, ground, the two poles of the earth, to improve its weldbonding manufacturability.
In the present embodiment, inflation inlet 3 is positioned at position, the arctic, and this inflation inlet 3 is made of pvc material, includes valve 5 and vent plug 4.
Fig. 2 illustrates the structure of inflation inlet.Valve 5 is column among the figure, and its upper port is connected with a vent plug 4.Be provided with two hangers 7 on valve 5, this hangers 7 is one-body molded with valve 5.Hangers 7 can be coated with rope band in the form of a ring in hangers 7, the utility model is hung.
The root 6 of valve 5 is frustum, and weldbonding is on spheroid, and this frustum root diameter (RD) is bigger.With hand vent plug 4, charging connector 3 can be pressed in the spheroid fully, show as Fig. 3.Make the terrestrial globe face shaping complete, the inflation inlet of reason protrusion does not destroy its outward appearance.
Fig. 4 illustrates second kind of embodiment of the present utility model, in the present embodiment, be positioned at the locational end socket 8 in ground, the two poles of the earth and be coniform, and inwardly concave, utilize existing globe bracket two fulcrums to withstand on this recessed portion the utility model is rotated on support, be more conducive to observe.
The utility model can make the interior gassy after expansion of ball form a spheroid from inflation inlet 3 inflations in use, emits gas in the ball when not using, and it is folding.The utility model outside surface can be printed on regional distribution chart, topography profile, animal distribution plan, the map of mineral deposit, Traffic Distribution figure etc.
The utility model is compared with prior art and is had the following advantages:
1. volume is collapsible, is easy to carry, and is easy to use;
2. manufacturing cost is extremely low, and processing is simple;
3. can arbitrarily increase volume, and it is minimum to increase cost;
4. the utility model can be made teaching aid, can be used as toy again, can produce the beneficial effect of teaching through lively activities;
5. the utility model also can be used as sports goods, as land or low intensive sports equipment waterborne, also can be used as a ball float on the water.
Claims (4)
1, a kind of inflatable terrestrial globe is characterized in that: form a spheroid that seals by the identical polyethylene film sheet weldbonding of shape, on each bar weldbonding seam 2 a certain warp that are positioned on the terrestrial globe; Be provided with inflation inlet 3 on position, terrestrial globe polar region, have two hangers 7 on this inflation inlet 3, the root of inflation inlet 3 is frustum; On position, ground, the two poles of the earth, have end socket respectively.
2,, it is characterized in that inflation inlet 3 is positioned on the position of the terrestrial globe arctic according to the inflatable terrestrial globe of claim 1.
3,, it is characterized in that polyethylene film sheet 1 can be six or nine or 12 according to the inflatable terrestrial globe of claim 1.
