Description
Technical field
The utility model relates to curved surface demonstration teaching aid field, relates in particular to a kind of teaching aid of higher mathematics mean camber demonstration.
Background technology
Higher mathematics is extremely important for most of students, and because a lot of concepts in higher mathematics are very abstract, it is simple that to explain student by teacher be very indigestible, the especially curvature portion in higher mathematics, and curved surface is one of main object of infinitesimal geometry research.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of teaching aid of higher mathematics mean camber demonstration is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of teaching aid of higher mathematics mean camber demonstration, comprise base, vertical rod and crossbeam, base both sides are provided with vertical rod, two vertical rod upsides are fixedly installed crossbeam, base center is provided with screw rod, screw rod lower end is fixedly installed lower half circle, upper end is fixedly installed upper semi-circle, screw tip one side is provided with change gear one, change gear one other end is connected with dwang, and the dwang other end is provided with change gear two, and change gear two upper ends are provided with handle, left side, crossbeam upper end is provided with power supply, and power supply is connected with motor by wire.
Between further described lower half circle and upper semi-circle, be provided with annulus, screw rod upper end is provided with screw thread, is provided with switch on power supply, and motor front end and screw rod are fixed together, and motor is stablized fixing by fixed mount.
The utlity model has following beneficial effect:
The teaching aid of higher mathematics mean camber demonstration of the present utility model, can manual operation also can automatic rotation, can show multiple different curved surface and parabola, can make student vividly, objectively understand the concept of curved surface, make student improve learning interest, improve the effect of giving lessons, simple in structure, the teaching that is applicable to higher mathematics is used.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1, a kind of teaching aid of higher mathematics mean camber demonstration, comprise base 1, vertical rod 2 and crossbeam 3, base 1 both sides are provided with vertical rod 2, two vertical rod 2 upsides are fixedly installed crossbeam 3, base 1 center is provided with screw rod 4, screw rod 4 lower ends are fixedly installed lower half circle 5, upper end is fixedly installed upper semi-circle 6, screw rod 4 top one sides are provided with change gear 1, change gear one 9 other ends are connected with dwang 8, dwang 8 other ends are provided with change gear 2 10, change gear 2 10 upper ends are provided with handle 11, crossbeam 3 left sides, upper end are provided with power supply 12, power supply 12 is connected with motor 16 by wire 14.
Between further described lower half circle 5 and upper semi-circle 6, be provided with annulus 7, screw rod 4 upper ends are provided with screw thread 15, are provided with switch 13 on power supply 12, and motor 16 front ends and screw rod 4 are fixed together, and motor 16 is stable fixing by fixed mount 17.
On mathematics class, teacher wants to demonstrate surface of revolution, as long as wave with hand control handle 11, the circle that lower half circle 5 and upper semi-circle 6 are combined into will be rotated, and shows curved surface to student.For dissimilar curved surface, as long as upper semi-circle 6 is rotated along the screw thread 15 on screw rod 4, up-down adjustment, just can obtain circle or ellipse etc., and then obtain different curved surfaces.The curved surface forming for para-curve, as long as annulus 7 is taken off, takes down upper semi-circle 6 or lower half circle 5 and just can obtain different para-curve, and then rotation obtains different parabolas, be convenient to the understanding of student to different curve, the quadric surface in learning higher mathematics, convenient understanding.When teacher is inconvenient to operate, as long as the switch 13 of opening power 12, motor 16 will drive screw rod 4 to rotate, and need not teacher start, and teacher just can coordinate other eastern two teaching like this, improves the efficiency of attending class.
In sum; a utility model only embodiment of the teaching aid to the demonstration of higher mathematics mean camber is illustrated; but the utility model is not limited to this; it will be appreciated by those skilled in the art that in the case of not departing from the protection domain that claims of the present utility model record and can change arbitrarily and revise.
