Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-3, a kind of physical teaching aid, including magnetic stripe A1, magnetic stripe B2, weightening finish block 3, magnet A 4, dolly 5, swash plate 6, matsurface A7, matsurface B8, matsurface C9, magnetic stripe C10, casing 11, matsurface D12, switch 13, electromagnet apparatus 14, Magnet D15, iron plate 16 and handle 17; On the left of described casing 11, box body wall is provided with magnetic stripe A1 and magnetic stripe B2, magnetic stripe A1 and is used for adsorbing magnetic stripe C10, when equipment not used time, dolly 5 and weightening finish block 3 are all adsorbed on magnetic stripe B2; Described weightening finish block 3 is provided with magnet A 4; Described dolly 5 upper surface is provided with Magnet D15, and lower surface is provided with iron plate 16; Described magnet A 4 and Magnet D15 adsorb mutually, for increasing the quality of dolly 5; Being provided with a platform in described casing 11, be used for placing dolly 5, platform is connected with swash plate 6; Described swash plate 6 is divided into four slopes, swash plate 6 end to be connected through the hinge matsurface; Described matsurface is divided into matsurface A7, matsurface B8, matsurface C9 and matsurface D12, and wherein matsurface A7 is identical with the coefficient of friction of matsurface B8, and matsurface is collapsible simultaneously; Described magnetic stripe C10 is arranged on baffle plate section; The back side of described matsurface is provided with handle 17, is convenient for carrying casing 11; Being provided with switch 13 and electromagnet apparatus 14 in described casing 11, be energized and power-off by switching 13 control electromagnet apparatus 14, during power-off, electromagnet apparatus 14 loses magnetism, thus with the iron plate 16 on dolly 5 separately, dolly 5 drops down onto matsurface from slope slip up automatically; After demonstration terminates, being folded by matsurface, now magnetic stripe A1 and magnetic stripe C10 adsorbs mutually, so that whole casing 11 is combined into an entirety.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
