Abstract
The utility model discloses a chromosome and gene action demonstrator, which comprises a base plate which represents cells and a strip-type body which represents a chromosome, wherein the base plate is a metal base plate which has an oval shape; a circle of edge convex strip which represents a cell wall and cell membrane structure is arranged at a position close to the edge of the metal base plate; the strip-type body which represents the chromosome comprises two crossed single strip-type bodies; and a magnetic device for attracting the strip-type body onto the metal base plate is arranged in the strip-type body. The base plate is made of metal such as iron; a magnet is arranged in the strip-type body which represents the chromosome, so that the strip-type body can be attracted to the base plate conveniently and can be disassembled to be combined into required chromosomes; therefore, teaching demonstration is quite convenient; and the whole demonstrator has a simple structure and is low in cost and easy to manufacture.
Description
Technical field
The utility model relates to the teaching aid technical field, is specifically related to a kind of instructional device that is used to demonstrate chromosome and gene behavior.
Background technology
The division of cell and fusion are the various actions that chromosome produces, and are the bases of explaining the biological heredity rule, because chromosomal various actions are that naked eyes can't be observed, therefore can seem more abstract, when teaching, have one difficulty.In order to address this problem; Someone has designed a kind of presentation tool, and it comprises four parts: plastic casing, ringshaped magnet, iron bar structure and base plate, ultimate principle are the ringshaped magnet absorption iron bar structures that makes plastic casing interior; So a large amount of ringshaped magnets must be set; Be distributed widely in the plastic casing, make more complicated, and cost be very high; Because ringshaped magnet can not be accomplished even distribution, cause some inconveniences can for the demonstration operation in addition.
The utility model content
The technical matters that the utility model will solve provide a kind of rational in infrastructure, easy to operate, make simple, that cost is low chromosome and gene behavior demonstration device.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of chromosome and gene behavior demonstration device is characterized in that: comprise the base plate of representing cell and represent chromosomal strip shape body; Said base plate is a metal base plate, and metal base plate is an oval shape, is provided with the edge raised line that a circle is represented cell membrane and cell membrane structure in the position near the metal base plate edge; Represent chromosomal strip shape body to comprise single strip shape body that two intersections connect together, be provided with in the strip shape body and can make it be adsorbed on magnetic devices on the metal base plate.
Further, said metal base plate is iron plate or steel plate.
Further, one in two single strip shape bodies of composition strip shape body is provided with projection, and another is provided with the fixed orifice that is complementary with projection, and two single strip shape bodies are inserted in the fixed orifice through projection and combine.
Further, said magnetic devices is a magnet, and magnet is embedded the inside at strip shape body.
Further, on the surface of strip shape body, be provided with and represent gene letter.
The utility model is made base plate through adopting metals such as iron; In the chromosomal strip shape body of representative, magnet is set then; Strip shape body can be adsorbed on base plate easily like this, and strip shape body can take apart and be combined into the chromosome that needs each other, makes that like this teaching demonstration operation is quite convenient; And whole apparatus structure is simple, cost is low, be easy to manufacturing.
Description of drawings
Fig. 1 is the utility model base plate plane structural representation;
Fig. 2 representes the structural representation of chromosomal strip shape body for the utility model;
Fig. 3 is the structural representation that dissects of strip shape body.
Among the figure, 1 is metal base plate, and 2 is the edge raised line, and 3 is strip shape body, and 4 is projection, and 5 is letter, and 6 is magnet.
Embodiment
In the present embodiment, with reference to Fig. 1, Fig. 2 and Fig. 3, said chromosome and gene behavior demonstration device comprise the base plate of representing cell and represent chromosomal strip shape body 3; Said base plate is a metal base plate 1, and metal base plate 1 is an oval shape, promptly is similar to the shape after cell cuts, and is provided with the edge raised line 2 that a circle is represented cell membrane and cell membrane structure in the position near metal base plate 1 edge; Represent chromosomal strip shape body 3 to comprise single strip shape body that two intersections connect together, be provided with in the strip shape body and can make it be adsorbed on magnetic devices on the metal base plate 1.
One in two single strip shape bodies of composition strip shape body 3 is provided with projection 4, and another is provided with the fixed orifice that is complementary with projection 4, and two single strip shape bodies are inserted in the fixed orifice through projection 4 and combine.
Magnetic devices is a magnet 6, and magnet 6 is embedded the inside at strip shape body 3.
On the surface of strip shape body 3, be provided with and represent gene letter 5.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
