Abstract
Disclosed is a device for demonstrating the image of a helix function, and the device comprises a pedestal, and a vertical column disposed on the pedestal. The device is characterized in that the pedestal is provided with a slide rail, that the vertical column is located inside the slide rail, that the vertical column is provided with a slide groove, that a magnetic slide block is placed inside the slide groove, that the magnetic slide block is provided with a through hole, and that the interior of the through hole is provided with a winding line for representing a graph of a function. The pedestal is divided by the slide rail into a plurality of bosses. The top of a side surface of each of the plurality of bosses is provided with a concave platform which can accommodate the magnetic slide block. The tops of the bosses and the circumferential surface of the vertical column are provided with coordinate points. The device is characterized by reasonable design of structure, ingenious and novel conception, good simplicity and practicality, three-dimensional structure convenient for students to understand and to make compact lessons, so as to attract attentions of the students and bring convenience for the students to understand knowledge actually. Moreover, the device is applicable for expressing images of helix functions, space curve circles, ellipses and the like.
Description
Technical field:
The utility model belongs to teaching aid, is specifically related to the image demonstration device of helix function.
Background technology:
In the helix Function Teaching work of reality, most teachers can only explain without foundation, and the student can only understand by the imagination, and such efficiency of teaching is very low.Although the school that has has used multimedia teaching, when lecturing this part knowledge, demonstrate image with computer, but the forming process of functional picture is subjected to the impact of computer program, the student can not understand the essence of helix function clearly, the student is understood the application of helix function be restricted.
The utility model content
The purpose of this utility model is the weak point that exists in order to overcome above-mentioned prior art, and a kind of image demonstration device of helix function is provided, and it is simple in structure, easy to use, is easy to large-scale promotion application.
The technical solution adopted in the utility model is: the image demonstration device of this helix function, comprise base and be located at column on the base, it is characterized in that: described base is provided with slideway, column is positioned at slideway, described column is provided with chute, the magnetic force slide block is placed in the described chute, described magnetic force slide block is provided with the through hole that the coiling of representative function image is passed, described slideway is divided into some boss with described base, and the top of described boss one side is provided with the concave station that can hold the magnetic force slide block;
Be equipped with coordinate points on the end face of the above boss and the side face of column.
Preferably, the column lower end described in the utility model is provided with projection, and the side bottom of described boss be provided be mated groove.
Preferably, when the slide block of magnetic force described in the utility model was sitting on the bottom surface of described concave station, the center line of the through hole on the magnetic force slide block was concordant with the end face of described boss.
Description of drawings
Fig. 1 is one-piece construction figure of the present utility model;
Fig. 2 is the partial enlarged drawing at the utility model I place;
Fig. 3 is the partial enlarged drawing at the utility model II place.
Embodiment
Below in conjunction with each accompanying drawing embodiment of the present utility model is further described.
A kind of image demonstration device of helix function, comprise base 1, and be located at column 2 on the base 1, described base 1 is provided with slideway 11, described slideway 11 is divided into some boss 12 with described base 1, described column 2 is positioned at slideway 11, and column 2 lower ends are provided with projection 22, and the side bottom of described boss 12 be provided be mated groove 122; Described column 2 is provided with chute 21, and magnetic force slide block 3 is placed in the described chute 21, and described magnetic force slide block 3 is provided with the through hole 31 that the coiling 4 of representative function image is passed; The top of one side of described boss 12 is provided with the concave station 121 that can hold magnetic force slide block 3, described magnetic force slide block 3 operationally is sitting on the bottom surface of described concave station 121, when described magnetic force slide block 3 is sitting on the bottom surface of described concave station 121, the center line of the through hole 31 on the magnetic force slide block 3 is concordant with the end face of described boss 12, is equipped with coordinate points on the side face of the end face of the above boss 12 and column 2.
Below in conjunction with specific embodiment the course of work of the present utility model is described further.
The teacher is when explanation helix function, first base 1 is placed on the lectern, then adjusting post 2 is installed in the slideway 11, and magnetic force slide block 3 is installed on the chute 21 on the column 2, to wind the line according to the expression formula of helix function and 4 pass through hole 31, the track of coiling 4 can represent the image of required helix function.When the different helix function of explanation, by regulating the position of magnetic force slide block 3 and column 2, do not need the image that can obtain required helix function is taken off in coiling 4.The utility model reasonable in design, novelty is skillfully constructed, simple and practical, be more convenient for student's the understanding of three-dimensional spatial structure, make classroom rhythm compact, not only attract easily student's notice, the student that is more convenient for gets a real idea of relevant knowledge, and is applicable to represent the image of the many kinds of function such as helix function, space curve be round, oval.
