Description

A kind of novel terrestrial globe

Technical field

The present invention relates to a kind of teaching aid, refer to specifically a kind of novel terrestrial globe.

Background technology

Terrestrial globe is the earth model that dwindles, and the above indicates various countries and river, desert, ocean, lake etc.Terrestrial globe can be explained the earth owing to rotation and all spontaneous phenomenons that revolve around the sun obliquely and form visual and understandablely, so terrestrial globe has become necessary educational aid in modern geographical teaching.Terrestrial globe has following purposes in the studying the geography process: 1, rotation and the revolution of the demonstration earth, 2, understanding warp and weft characteristic distributions, 3, the distribution overview of understanding world Hai Lu, 4, the division of demonstration autobiography study world time zone.

Existing terrestrial globe, the spheroid that generally comprises base, is connected to the support on the base and rotates at support, its support is tortuous bow shape, and spheroid rotates around the minor axis that the support two ends form.Such globe type is too simple, installation is inconvenient, need open two axis holes that cooperate with minor axis at spheroid, and spheroid can only around single direction rotation, can't be realized arbitrarily in any direction upper rotation.

Summary of the invention

The invention provides a kind of novel terrestrial globe, its fundamental purpose is to overcome existing terrestrial globe can't realize the upper in any direction problems such as inconvenient of rotating, install.

In order to solve above-mentioned technical matters, the present invention adopts following technical scheme to be achieved:

A kind of novel terrestrial globe, comprise base, be installed on the support on the base and can rotate and the spheroid of light-permeable at support, described support comprises and is fixed on the support column on the base and is connected on the support column lateral wall and spaced apart at least three support bars, the upper end of each support bar all forms a lug, the medial surface of each lug all has one first inner chamber, be equipped with the first spring in each first inner chamber, one end of this first spring connects with the rearward end of the first corresponding inner chamber, its other end is connected with the first conflict ball, the upper surface of described support column has one second inner chamber, be provided with the second spring in this second inner chamber, one end of this second spring is connected with the bottom of the second inner chamber, and its other end is connected with the second conflict ball.

Further, also comprise a power supply-illumination system, this power supply-illumination system comprises that the solar panel that is installed on the base top surface, the accumulator that is installed in base inside be connected the LED lamp that is installed on spheroid inside and be connected a switch that is connected with the wireless power emitter with the wireless power receiving trap with the wireless power emitter, this switch is positioned on the sidewall of base, described solar panel is connected with storage battery, described accumulator is electrically connected with the wireless power emitter, and described LED lamp is electrically connected with the wireless power receiving trap.

Further, described support bar is three, and these three support bars are curved, and its lower end is fixedly connected on the lateral wall of support column 120 ° of angles of one-tenth between described two adjacent support bars.

Further, described base is arcuation.

Further, described support column is round table-like.

Further, described the first conflict ball and the second conflict ball are steel ball.

By the above-mentioned description of this invention as can be known, be compared with existing technology, the present invention has following advantage:

Novel structure of the present invention, attractive in appearance, practical; The first conflict ball and the second conflict ball play the effect of support to spheroid, need not when spheroid is opened axis hole, can realize that spheroid rotates in any direction, and spheroid also can take out separately use, easy for installation, the first conflict ball and the second conflict ball can roll in the first and second inner chambers, stretch and can not come off; The LED lamp that is installed in the spheroid can make spheroid at noctilucence, and by solar powered, power supply approach between LED lamp and the accumulator is become the transmission of being carried out electricity by wireless power emitter and wireless power receiving trap by original electric wire Innovation of Connection, need not to consider the line arrangement problem, night is when watching terrestrial globe, can in certain wireless power signal receiving area, independent taking-up of spheroid be watched, increase the dirigibility that terrestrial globe uses.
