Description
Technical field
The utility model relates to a kind of teaching demonstration device, particularly a kind of apparatus for demonstrating of hyperbolic slit.
Background technology
Hyperbolic curve is that the axle rotation generates the hyperboloid of one sheet around the middle separated time of two focuses.The hyperboloid of one sheet is a kind of dual ruled surface, so has straight edge line on the hyperboloid of one sheet.If this straight edge line is rotation take the middle separated time of hyperbolic focus as axle, can form the curved surface identical with the former hyperboloid of one sheet.In present teaching, there is no corresponding apparatus for demonstrating, this theory is very abstract, needs the certain space thinking ability to understand.Obviously in the situation that the shortage apparatus for demonstrating has increased teaching difficulty.
Summary of the invention
The utility model provides a kind of apparatus for demonstrating of hyperbolic slit, and purpose is to show that clearly there is straight edge line in the hyperboloid of one sheet.
For solving the problems of the technologies described above, the utility model is taked following technical proposal:
A kind of apparatus for demonstrating of hyperbolic slit comprises base, hyperbolic curve wallboard, straight rod, center stand column, and described center stand column is vertically mounted on described base, can be take self axis as the axle rotation, and described straight rod is fixedly mounted on described center stand column by connecting link; Described straight rod is fixedly mounted on described center stand column by connecting link, and the axis of described straight rod and the axis of described center stand column are non-intersect, and favours the upper surface of described base; Described hyperbolic curve wallboard is vertically mounted on described base, and with the dead in line of described center stand column; The intersection of the hyperboloid of one sheet on described hyperbolic curve wallboard that produces when described slotted eye and described straight rod rotate take center stand column as axle adapts.
Described base is square box, described center stand column is provided with the rotating shaft coaxial with described center stand column in described base, described base one side is equipped with wind, and described wind is provided with the rotating shaft of stretching in described base, and is connected with the rotating shaft of described center stand column by umbrella tooth gear train.
Described hyperbolic curve wallboard has four, is arranged on the diagonal line of upper surface of described base.
Described connecting link is connected to the center section of described straight rod.
Be provided with stent wall between described hyperbolic curve wallboard.
The utility model adopts said structure, and show straight rod is the single page hyperboloid rotate the space structure that generates around center stand column clearly, thereby explanation single page hyperboloid has straight edge line.And simple to operate, use safety.
Description of drawings
The below is briefly described the expressed content of each width accompanying drawing of this instructions and the mark in figure:
Fig. 1 is the structural representation of the apparatus for demonstrating of a kind of hyperbolic slit of the utility model;
Fig. 2 is the left view of structure shown in Figure 1;
Fig. 3 is the vertical view of structure shown in Figure 1;
Fig. 4 is the schematic perspective view of structure shown in Figure 1.
Be labeled as in figure: 1, hyperbolic curve wallboard; 2, straight rod; 3, stent wall; 4, center stand column; 5, base; 6, base side plate; 7, umbrella tooth gear train; 8, slotted eye; 9, wind.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail, and to help those skilled in the art, inventive concept of the present utility model, technical scheme is had more complete, accurate and deep understanding.
As shown in Figures 1 to 4, the utility model provides a kind of apparatus for demonstrating of hyperbolic slit, comprise base 5, hyperbolic curve wallboard 1, straight rod 2, center stand column 4, wherein base 5 is square box, center stand column 4 is vertically mounted on this base 5, and is provided with the rotating shaft with described center stand column 4 coaxial cables in described base 5, and wind 9 is equipped with in the outside of a base side plate 6, wind 9 is provided with rotating shaft in base 5, the rotating shaft below center stand column 4 is connected by umbrella tooth gear train 7.Rotary handle crank 9 can drive center stand column 4 rotations.
During demonstration, rotate and drive center stand column 4 rotations, above-mentioned straight excellent 2 also can rotate thereupon.Because the intersection of the hyperboloid of one sheet on hyperbolic curve wallboard 1 that the slotted eye on the hyperbolic curve wallboard 8 produces when rotating take center stand column 4 as axle with straight rod 2 adapts, so straight rod 2 slotted eyes 8 that can pass on the hyperbolic curve wallboard, this obviously solid figures of generating of straight rod 2 rotations of explanation are hyperboloid of one sheets, and the intersection of this hyperboloid of one sheet and hyperbolic curve wallboard 1 and slotted eye 8 shapes on hyperbolic curve wallboard 1 adapt.Use this apparatus for demonstrating simple to operate laborsaving, principle demonstration is intuitively clear.
The above is exemplarily described the utility model by reference to the accompanying drawings, obviously exclusive list not.Therefore, the utility model specific implementation is not subject to the restrictions described above.As long as adopted the change of the various unsubstantialities that method of the present utility model design and technical scheme carry out, or without improvement, inventive concept of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
