Wherein, 1-base, 2-column, 3-through hole, 4-axle sleeve, 5-axostylus axostyle, 6-rotating disk, 7-handle, 8-para-curve, 11-universal wheel, 12-hydraulic cylinder, 13-lower margin, 16-rotating shaft, 17-lamp stand, 18-lamp cylinder, 19-bulb.
Embodiment
The utility model is elaborated preferred embodiment below in conjunction with accompanying drawing.
The parabola demonstration teaching aid that a kind of College Mathematics Teaching uses, comprise base 1, two ends on described base 1 are provided with column 2, the upper end of described column 2 is provided with through hole 3, axle sleeve 4 is provided with in described through hole 3, axostylus axostyle 5 is provided with in described axle sleeve 4, one end of described axostylus axostyle 5 is provided with external thread, also comprise rotating disk 6, the centre position of described rotating disk 6 is provided with the threaded hole matched with external thread, the sidewall of described rotating disk 6 is provided with the blind hole of interior four ribs, also comprise hand cranking handle 7, described hand cranking handle 7 is provided with outer four ribs matched with interior four ribs, the other end of described axostylus axostyle 5 is provided with para-curve 8, the bottom of described base 1 is provided with universal wheel 11, the avris of described universal wheel 11 is provided with hydraulic cylinder 12, the bottom of described hydraulic cylinder 12 is provided with lower margin 13, described axle sleeve 4 is hinged with telescopic lamp stand 17 by rotating shaft 16, the termination of described lamp stand 17 is provided with lamp cylinder 18, bulb 19 is connected with by lamp socket in described lamp cylinder 18.The length of described axostylus axostyle 5 is greater than the length of axle sleeve 4.
Para-curve 8 is made for plastic material, the summit place of para-curve 8 is fixedly connected with axostylus axostyle 5, rotating disk 6 is fixed on axostylus axostyle 5 by threaded hole with externally threaded cooperation, fixed further by clamp nut, prevent rotating disk 6 from loosening on axostylus axostyle 5, shake handle 7, rotating disk 6 drives axostylus axostyle 5 to rotate in axle sleeve 4, para-curve 8 on axostylus axostyle 4 rotates, and demonstrates out paraboloidal formation.
Hydraulic cylinder 12 is provided with hydraulic pressure pedal, presses pedal, and the piston rod in hydraulic cylinder 12, by base 1 jack-up, regulates the height be applicable to, and convenient student viewing study below, lower margin 13 pairs of hydraulic cylinders 12 support.Avoid the movement of universal wheel 11, base 1 is unstable, affects demonstrating effect.Can be carried out by universal wheel 11 after demonstration.
Bulb in lamp cylinder 18 19 pairs of para-curves 8 throw light on, so that student sees clearly to paraboloidal formation, after using, the retraction of lamp stand 17, is merged by the top of rotating shaft 16 with axle sleeve 4, conveniently deposit.
Present embodiment does not just limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the Spirit Essence exceeding this patent, be all considered as the equivalent replacement to this patent, all at the protection domain of this patent.
