Description
Technical field
The utility model relates to teaching tool technical field, is specifically related to College Maths surface of revolution demonstration teaching aid.
Background technology
Surface of revolution rotates a circle formed curved surface surface of revolution with the straight line of a plane curve in its plane, and rotating curve and boning out are called bus and the axle of surface of revolution successively.Surface of revolution is a part for more complicated in University Space cartesian geometry, because there is no the demonstration model for teaching of image, be difficult to fully understand, this brings very large difficulty to teaching process, current surface of revolution demonstration teaching aid only facilitates student from four direction observation all around, is inconvenient to the observation of carrying out overlooking or look up angle, makes demonstration result can not show student completely, and displaying contents is abundant not, cause demonstrating inefficiency.
Summary of the invention
The purpose of this utility model is just to provide College Maths surface of revolution demonstration teaching aid to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: College Maths surface of revolution demonstration teaching aid, comprise firm banking, transverse groove, longitudinal draw-in groove, cannelure, telescopic supporting rod, rotating curve, rotary main shaft and center fixed bar, described firm banking offers transverse groove and cannelure, and firm banking upper surface centre position is provided with center fixed bar, described transverse groove offers longitudinal draw-in groove, described telescopic supporting rod is connected with rotating curve, the described rotary main shaft left and right sides is fixedly connected with telescopic supporting rod, described rotary main shaft lower end is connected with center fixed bar, and rotary main shaft can rotate around center fixed bar.
Preferably, described center fixed bar can move in transverse groove and cannelure.
Preferably, described telescopic supporting rod can change length and each retractable support pole length change be independent of each other.
Preferably, rotating curve scribbles fluorescent paint, and rotating curve is soft rubber.
The beneficial effects of the utility model are: this apparatus structure is simple, handsome in appearance, use simple, demo content enriches, observable angle is many, and night, observing effect was good, can change the shape of rotating curve manually, also can be changed the size and shape of required demonstration curve by the length changing telescopic supporting rod, improve the efficiency of teaching.
Accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
In figure: 1, firm banking, 2, transverse groove, 3, longitudinal draw-in groove, 4, cannelure, 5, telescopic supporting rod, 6, rotating curve, 7, rotary main shaft, 8, center fixed bar.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
1 describe by reference to the accompanying drawings, the utility model College Maths surface of revolution demonstration teaching aid, comprise firm banking 1, transverse groove 2, longitudinal draw-in groove 3, cannelure 4, telescopic supporting rod 5, rotating curve 6, rotary main shaft 7 and center fixed bar 8, described firm banking 1 offers transverse groove 2 and cannelure 4, and firm banking 1 upper surface centre position is provided with center fixed bar 8, for supporting rotary main shaft 7, described transverse groove 2 offers longitudinal draw-in groove 3, described telescopic supporting rod 5 is connected with rotating curve 6, described rotary main shaft 7 left and right sides is fixedly connected with telescopic supporting rod 5, described rotary main shaft 7 lower end is connected with center fixed bar 8, and rotary main shaft 7 can rotate around center fixed bar 8, described center fixed bar 8 can be mobile in transverse groove 2 with cannelure 4, center fixed bar 8 can be placed in longitudinal draw-in groove 3, change demonstration viewing angle, improve demonstration efficiency, described telescopic supporting rod 5 can change length and the change of each telescopic supporting rod 5 length is independent of each other, make rotating curve 6 change of shape more diversified, add the rich of demonstrated curved surface, and then raising efficiency of teaching, rotating curve 6 scribbles fluorescent paint, make this teaching aid under dark surrounds, demonstrating effect is more vivid, be convenient to teaching, and rotating curve 6 is soft rubber, teacher can reach teaching purpose according to the shape of field research demand change rotating curve 6.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
