Description
Technical field
The present invention relates to a kind of model teaching aid, relate in particular to virus model teaching aid.
Background technology
Microbiological development has promoted the mankind's progress, comprises the contribution to life science fundamental research, and propelling to production practices such as health care, industrial fermentation, agricultural production and environmental protection.
But the individuality of microorganism is too small, colony's appearance is not obvious etc., itself characteristic and limitation cause the microorganism long-term lacking cognition that the mankind are huge for quantity, distributed pole is wide.After microbiology rises, increasing field applies to microbiology, and increasing people's microorganisms is learned.In the process of study research, need to observe with microscope, understand for shape, the structure etc. of microorganism.But in the process of teaching, if will explain to students the feature of a certain microorganism, it is not all right only depending on viewing microscope, because the picture that everyone sees is different, the thing of understanding is just different, and teacher also can not point out the concrete structure of microorganism very intuitively.
Often can run into some viruses at the aspect such as microbiology, pathology; then teacher conventionally can only be with photo or the structural representation of drafting etc. of image that electron microscope becomes at these viral morphosis of explanation; but these pictures are merely able to represent viral form and outward appearance; can not show a three-dimensional spatial structure, more can not see intuitively viral internal structure.And more existing teaching aids are all fixed structures, can not allow student start to combine, therefore the model teaching aid of stationary structure is unfavorable for enhancing memory.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, easy to carry, spherical viruses model teaching aid that can represent well virus structure.
For achieving the above object, the technical solution used in the present invention is: a kind of spherical viruses model teaching aid, it comprises spheroidite, structural poles, corner block, described spheroidite is spheroid, described structural poles be an end face evenly distributed along its length four hemispheroidal rectangular parallelepipeds, described corner block is evenly distributed six the hemispheroidal regular triangular prisms of an end face; Described spheroidite is as summit, described structural poles is as rib, described corner block forms a complete icosahedron together as face, on described spheroidite, be provided with furcella, described furcella is the spheroid that a bottom is provided with connecting link, described connecting link one end connects described spheroid, and one end connects described spheroidite.
Preferably, be provided with triangle projection in described structural poles two sides, there is the depression that coordinates described spheroidite radian on two tops, in described depression, are provided with magnet.
Preferably, on three sides of described corner block, be provided with the groove that coordinates described triangle projection.
Preferably, described structural poles, described corner block material are plastics, and described spheroidite, furcella material are magnetic metal material.
In technique scheme, spheroidite, furcella are magnetic metal material, spheroidite, furcella are fixedly connected with, the structural poles that two ends are provided with magnet can be adsorbed on spheroidite, and on two sides of structural poles, there is triangle projection, like this, three arrange reeded corner block and just can be stuck in the middle of three structural poles; Use 12 spheroidites, furcella, 20 corner blocks, 30 structural poles just can form a complete icosahedron.
Further technical scheme, described furcella can be arranged on described spheroidite for disassembly and assembly structure, and described furcella connecting link bottom is provided with magnet, and described furcella material is plastics.
In technique scheme, furcella and spheroidite are disassembly and assembly structures, and the magnet adsorption that furcella arranges by furcella connecting link bottom is on spheroidite.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1,, because structure of the present invention is 3-D solid structure, can make observer be well understood to outward appearance and the structure of spherical viruses.
What 2, adopt due to the present invention is disassembly and assembly structure, not only can save transport space, reduces transportation cost, can also increase user's manipulative ability, enhances memory, and more understands viral structure in depth.
3, because main material of the present invention is plastics, can not only save some costs, and can manufacture multicolour, with different functions of each appearance similar in color mark virus, the parts of different structure.
