Abstract
The utility model relates to a demonstration-facilitating saddle surface mathematical teaching aid and relates to a saddle surface mathematical teaching aid. With the demonstration-facilitating saddle surface mathematical teaching aid of the utility model adopted, the problems of unclear structure and incapability of achieving anticipated teaching effect of an existing saddle surface mathematical teaching aid can be solved. According to the demonstration-facilitating saddle surface mathematical teaching aid of the utility model, a cross beam is arranged above a rectangular base; the cross beam is connected with the rectangular base through a triangular support; the rectangular base is provided with a coordinate system; both ends of a bus are detachably arranged on the cross beam through a fixing bolt respectively; two edge boards are arranged on long edges of the rectangular base; one end of each parabola is detachably arranged on one edge board; the other end of each parabola is arranged on the bus through a clamp and thereafter is detachably arranged on the other edge board; two fixing plates are arranged on the two long edges of the rectangular base; each fixing plate is provided with an adjusting bolt; and screw thread ends of the adjusting bolts abut against the edge boards. The demonstration-facilitating saddle surface mathematical teaching aid of the utility model is used for mathematics teaching.
Description
Technical field
The utility model relates to a kind of saddle face mathematical education teaching aid, is specifically related to a kind of saddle face mathematical education teaching aid of being convenient to demonstrate.
Background technology
Higher mathematics is the key discipline in colleges and universities, for the student, it is also a subject that finds it difficult to learn very much, because higher mathematics is very abstract, a lot of students rely on imagination can't reach the effect of giving lessons of expection, especially space analysis how much chapters, find in the process of giving lessons, the student is comparatively difficult to the saddle foliation solution in quadric surface, publication number is to disclose a kind of saddle face teaching aid in the patent of 202694633U, but existing saddle face mathematics teaching aid exists the structure of saddle face unintelligible, can't reach the expection effect of giving lessons.
The utility model content
The purpose of this utility model is the problem that exists in existing background technology in order to solve, and then a kind of saddle face mathematical education teaching aid of being convenient to demonstrate is provided.
the technical solution of the utility model is: a kind of saddle face mathematical education teaching aid of being convenient to demonstrate comprises crossbeam, A-frame, rectangular base, bus, many para-curves, two margin plates, two set bolts, a plurality of clips, two fixed heads and two adjustment bolts, crossbeam is arranged on the top of rectangular base, connect by A-frame between crossbeam and rectangular base, rectangular base is provided with coordinate system, the two ends of bus detachably are arranged on crossbeam by a set bolt respectively, two margin plates are separately positioned on the long limit of rectangular base, an every parabolical end detachably is arranged on a margin plate, after being arranged on bus by a clip, the every parabolical other end detachably is arranged on another margin plate, two fixed heads are separately positioned on two long limits of rectangular base, each fixed head is provided with one and adjusts bolt, and thread end and the margin plate of adjusting bolt offset.
Be printed on scale value on the coordinate system of described rectangular base.
Described margin plate is the flexible skirt plate.
The utility model compared with prior art has following effect:
1. the utility model is simple in structure, easy operating, and also rectangular base is provided with coordinate system, can be according to the different different saddle face of Surface Parameters demonstration, and it is more accurate to demonstrate.
2. demonstration of the present utility model is more three-dimensional directly perceived, is convenient to observation of students and understanding, and the conversion of curve is brighter and clearer.
3. the utility model is easy to carry.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises crossbeam 1, A-frame 2, rectangular base 3, bus 4, many para-curves 5, two margin plates 6, two set bolts 7, a plurality of clips 8, two fixed heads 9 and two adjustment bolts 10, crossbeam 1 is arranged on the top of rectangular base 3, connect by A-frame 2 between crossbeam 1 and rectangular base 3, rectangular base 3 is provided with coordinate system, the two ends of bus 4 detachably are arranged on crossbeam 1 by a set bolt 7 respectively, two margin plates 6 are separately positioned on the long limit of rectangular base 3, one end of every para-curve 5 detachably is arranged on a margin plate 6, after being arranged on bus 4 by a clip 8, the other end of every para-curve 5 detachably is arranged on another margin plate 6, two fixed heads 9 are separately positioned on two long limits of rectangular base 3, each fixed head 9 is provided with one and adjusts bolt 10, and thread end and the margin plate 6 of adjusting bolt 10 offset.
As a kind of optimal way, be printed on scale value on the coordinate system of the rectangular base 3 of present embodiment.Be convenient to adjust accurately the parameter that forms the saddle face.
As a kind of optimal way, the margin plate 6 of present embodiment is the flexible skirt plate.Be more prone to when forming the saddle face.
The utility model according to different parameters, is selected the bus 4 of different length in use, and bus 4 can be by unscrewing and the bolt 7 that is tightened is regulated.Margin plate 6 by adjust bolt 10 unscrew and screw regulate.The length and location of many para-curves 5 is regulated after all opening by clip 8.The structure of whole saddle face consists of brighter and clearer, and the variation of each details may cause the change of whole shape, is convenient to the teacher and draws inferences about other cases from one instance when giving lessons, and gives lessons effective.
