Therefore, be necessary very much to provide a kind of curve presentation device of limit of function.
Utility model content
For the problems of the prior art, the utility model proposes a kind of teaching equipment.This equipment comprises the support bar of base, apparatus for demonstrating, connection base and apparatus for demonstrating.This apparatus for demonstrating comprises irony substrate, the multiple magnetic clasps that are connected with irony substrate and the demonstration lines that are connected with irony substrate by magnetic clasp.
Preferably, the surface of irony substrate is provided with coordinate diagram.
Preferably, the diameter range of demonstration lines is 0.5mm-1.5mm.
Preferably, the diameter range of magnetic clasp is 1cm-2cm.
Preferably, this teaching equipment also comprises the rule that is arranged on apparatus for demonstrating bottom.
Preferably, this teaching equipment also comprises at least one the scalable indicator stem that is arranged on apparatus for demonstrating bottom.
Preferably, the surface of scalable indicator stem is provided with length scale.
Preferably, support bar is multi-stage expansion structure.
Preferably, the lower end of apparatus for demonstrating is also provided with the tumbler for fixed support bar.
Preferably, the lower end of base is provided with wheel.
Utilize the application's teaching equipment, teacher can show the curve of limit of function easily, simple to operate, can Reusability.This apparatus for demonstrating has not only reduced teacher's labour intensity, and has reduced the drawing time, has further improved quality of instruction.In addition,, because this teaching equipment can regulate height and angle, be convenient to the student viewing of different angles.
Brief description of the drawings
In order better to understand the utility model, will be described embodiment of the present utility model according to the following drawings:
Fig. 1 is according to the structural representation of the teaching equipment of an embodiment of the utility model;
Fig. 2 is according to the structural representation of the teaching equipment of another embodiment of the utility model.
Embodiment
To describe specific embodiment of the utility model below in detail, it should be noted that the embodiments described herein, only for illustrating, is not limited to the utility model.In the following description, in order to provide thorough understanding of the present utility model, a large amount of specific detail have been set forth.But, it is evident that for those of ordinary skill in the art: needn't adopt these specific detail to carry out the utility model.In other examples, for fear of obscuring the utility model, do not specifically describe known circuit, material or method.
In whole instructions, " embodiment ", " embodiment ", " example " or mentioning of " example " are meaned: special characteristic, structure or characteristic in conjunction with this embodiment or example description are comprised at least one embodiment of the utility model.Therefore, differ and establish a capital the same embodiment of finger or example in each local phrase " in one embodiment ", " in an embodiment ", " example " or " example " occurring of whole instructions.In addition, can with any suitable combination and/or sub-portfolio by specific feature, structure or property combination in one or more embodiment or example.In addition, it should be understood by one skilled in the art that the accompanying drawing providing at this is all for illustrative purposes, and accompanying drawing not necessarily in proportion draw.
Fig. 1 is according to the structural representation of the teaching equipment of an embodiment of the utility model.As shown in Figure 1, mainly comprise two parts according to the teaching equipment of present embodiment: teaching support and the apparatus for demonstrating being connected with teaching support.
Teaching support comprises base 1 and support bar 3.Support bar 3 is fixedly connected with the top of base 1, and supports presentation tool 2.In the present embodiment, support bar 3 can multi-stage expansion.The lower end of apparatus for demonstrating 2 is provided with the tumbler 4 for fixed support bar 3.Can according to actual needs, by regulating support bar 3 and tumbler 4, realize height and regulate and angular adjustment.In addition, also can as required, set up wheel 5 in the bottom of base 1.
Apparatus for demonstrating 2 comprises irony substrate 21, multiple magnetic clasp 22 and at least one demonstration lines 23.Demonstration lines can be cotton ropes, can be also to have certain flexible material, as iron wire.The diameter range of iron wire can be 0.5mm-1.5mm.Magnetic clasp 22 is provided with through hole, and iron wire can pass through hole.Like this, by designing the position of multiple magnetic clasps 22, can realize specific functional digraph.
In the present embodiment, magnetic clasp 21 is cylindric, and the diameter range of circular surface can be 0.5cm-5cm.Preferably, diameter range can be 1cm-2cm.
The surface of irony substrate 21 also can arrange coordinate system 24, contributes to location and the understanding of figure.
Adopt the scheme of the present embodiment, utilize the magneticaction of magnetic clasp 22 and irony substrate 21, can easily form functional digraph by demonstration lines.The curve of the representative function limit can be recycled, and effectively reduces teacher's labour intensity, has solved the drawing time, has improved efficiency of teaching.
In addition, by telescopic rod and tumbler are set, can realize the adjusting to clipboard height and direction, be convenient to the student viewing study of different angles, effectively improve efficiency of teaching.
Fig. 2 is according to the structural representation of the teaching equipment of another embodiment of the utility model.As shown in Figure 2, also mainly comprise two parts according to the teaching equipment of present embodiment: teaching support and the apparatus for demonstrating 6 being connected with teaching support.
