Abstract
The invention provides a height-adjustable globe comprising a base and a support rod mounted on the base. The support rod is composed of a fixed rod and a telescopic rod. Therefore, the problem that the height of the existing globe cannot be adjusted is solved. When the globe is placed on desktops of different heights, teachers or students can adjust the height of the support rod of the globe for viewing at different heights without holding the globe with a hand. The height-adjustable globe is convenient and practical.
Description
Technical field
The present invention relates to a kind of Height Adjustable terrestrial globe.
Background technology
In existing geographical teaching, terrestrial globe is one of requisite learning tool of Faculty and Students, because existing terrestrial globe height is unadjustable, causes Faculty and Students to need the height of globe place, base area desk to go the viewing that comes back or bend over, or hand-held terrestrial globe is checked, very inconvenient.
Summary of the invention
The object of the invention is to solve the uncontrollable problem of existing terrestrial globe height.
For this reason, the invention provides a kind of Height Adjustable terrestrial globe, comprise base and be arranged on the support bar on base, described support bar is made up of fixed bar and expansion link.
The top of above-mentioned fixed bar is provided with a spacing hole.
The left and right sides of above-mentioned expansion link bottom is respectively arranged with a circular groove, is respectively arranged with three Compress Springs in this groove.
Above-mentioned groove port is provided with a ball-type spring top bead.
Above-mentioned spacing hole and spring top bead are interference fit.
Beneficial effect of the present invention: this Height Adjustable terrestrial globe provided by the invention, comprise base and be arranged on the support bar on base, described support bar is made up of fixed bar and expansion link.Therefore, the invention solves the uncontrollable problem of existing terrestrial globe height, when on the desktop that terrestrial globe is placed on differing heights, teacher or student need not hand-held terrestrial globes, only need regulate the height of the support bar of terrestrial globe, checking of differing heights can be realized, convenient and practical.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of Height Adjustable terrestrial globe.
Fig. 2 is the side view cutaway drawing of support bar.
Fig. 3 is the elevational cross-sectional view of support bar.
Description of reference numerals: 1, base; 2, support bar; 21, fixed bar; 22, expansion link; 3, spacing hole; 4, spring top bead; 5, groove; 6, spring.
Embodiment
Embodiment 1:
As shown in Figure 1, present embodiments provide a kind of Height Adjustable terrestrial globe, the support bar 2 comprising base 1 and be arranged on base 1, described support bar 2 is made up of fixed bar 21 and expansion link 22, the top of this fixed bar 21 is provided with a spacing hole 3, and the left and right sides of expansion link 22 bottom is respectively arranged with a circular groove 5, is respectively arranged with three Compress Springs 6 in this groove 5, groove port 5 is provided with a ball-type spring top bead 4, and above-mentioned spacing hole 3 and spring top bead 4 are interference fit.When terrestrial globe is in higher position, can spring top bead be pressed, make spring be in compressive state, in expansion link indentation fixed bar, as shown in Figure 2; When terrestrial globe is in lower position, expansion link can be extracted out, make spring top bead be stuck in spacing hole, spring is in extended state, as shown in Figure 3.Therefore, the invention solves the uncontrollable problem of existing terrestrial globe height, when on the desktop that terrestrial globe is placed on differing heights, teacher or student need not hand-held terrestrial globes, only need regulate the height of the support bar of terrestrial globe, checking of differing heights can be realized, convenient and practical.
The invention solves the uncontrollable problem of existing terrestrial globe height, when on the desktop that terrestrial globe is placed on differing heights, teacher or student need not hand-held terrestrial globes, only need regulate the height of the support bar of terrestrial globe, checking of differing heights can be realized, convenient and practical.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
