Description
Technical field
The utility model relates to a kind of model teaching aid, relates in particular to the head mold model teaching aid.
Background technology
Head mold is very wide in distributed in nature, and is of many uses, and its amylase activity is very strong, is saccharolytic commonly used in the brewery industry.China utilizes the head mold starch saccharification to produce alcohol the earliest.Head mold can be produced the organic acids such as fumaric acid, lactic acid, can also produce the Ester of aromaticity.Head mold also is the important mushroom that transforms steride.In the process of study research, need to observe with microscope, understand for the shape of head mold, structure etc.
In the prior art, the teaching aid in Students ' Interest in Microbiology Teaching all is the demonstrating model of fixing basically, and teacher points to the various piece of model and teaches at the dais, and the student lacks intuitively understanding, and composition and the relation of each several part also is difficult to memory.
Therefore need a kind of three-dimensional stereo model that can dismounting, can make student's Dismountable combination in study, in anabolic process, understand the structural form of microorganism.
Summary of the invention
The purpose of this utility model provides a kind of model teaching aid that can well represent again the head mold structure simple in structure, easy to carry.
For achieving the above object, the technical solution adopted in the utility model is: a kind of head mold model teaching aid, it comprises connecting portion, is arranged on the feet of described connecting portion below, is arranged on the vertical rod on the described connecting portion, described connecting portion is oval-shaped ball, described feet lower end is provided with bifurcated, described feet and described vertical rod are connected on the described connecting portion by slot card, be provided with at least three described vertical rods, wherein at least one described rod end is provided with the cone that the cone point makes progress, described cone surface is provided with a plurality of salient points, and all the other rod ends are provided with spheroid.
Preferably, described connecting portion side also is provided with connecting link, and two described connecting portions connect by described connecting link.
Preferably, described feet is provided with three.
Preferably, described vertical rod, described connecting link adopt resilient material to make.
In the technique scheme, described connecting portion represents the rhizoid of head mold and the place that the stolon intersection expands, described vertical rod represents the sporangiophore of head mold, described feet represents the rhizoid of head mold, described spheroid represents the sporangium of head mold, described cone represents columella and the apophysis in the head mold sporangium, and described salient point represents spore, and described connecting link represents the stolon of head mold.Utilize described connecting link can connect two connecting portions, namely can connect two described head mold model teaching aids.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model is a three-dimensional stereo model, can make the user be easier to understand structure and the principle of work of head mold, more be applicable to teaching.
2, because the utility model adopts disassembly and assembly structure, not only can save transport space, reduce transportation cost, can also increase user's manipulative ability, enhance memory, more understand structure and the principle of work of head mold in depth.
Description of drawings
Fig. 1 is the stereographic map of the utility model embodiment;
Fig. 2 is constitutional diagram.
Wherein: 1, connecting portion; 2, feet 3, vertical rod; 4, spheroid; 5, cone; 6, salient point; 7, connecting link.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described:
Embodiment one: shown in Fig. 1,2.
A kind of head mold model teaching aid, it comprises connecting portion 1, is arranged on the feet 2 of connecting portion below, is arranged on the vertical rod 3 on the connecting portion 1, connecting portion 1 is oval-shaped ball, feet 2 lower ends are provided with bifurcated, support pin 2 and vertical rod 3 to be arranged on the connecting portion 1 by slot, vertical rod 3 is provided with three, and two vertical rod 3 tops are provided with spheroid 4, vertical rod 3 tops are provided with the cone 5 that the cone point makes progress, and cone 5 surfaces are provided with a plurality of salient points 6.
The connecting portion side also is provided with 7, two connecting portions of connecting link 1 and connects by connecting link 7.Feet 2 is provided with three.Vertical rod 3, connecting link 7 adopt resilient material to make.Cone base can be distinguished with different colours and represent columella, apophysis.
Head mold model teaching aid assembling mode: feet 2, vertical rod 3 are installed on connecting portion 1 relevant position by buckle, again spheroid 4, cone 5 are installed in the top of vertical rod 3 by buckle, at last connecting link 7 is installed in connecting portion 1 side, by connecting link 7 a plurality of model combinations is installed.
In complete head mold model teaching aid, the basic structure and the action principle that have shown head mold, the mycelia that grows wild in stromal surface cries stolon (connecting link 7), and the place that stolon is expanded (connecting portion 1) bears rhizoid (feet 2) downwards, stretches in the matrix to draw nutrition; Upwards bear several upright sporangiophores (vertical rod 3), its ultimate swelling forms sporangium (spheroid 4), and there is a hemispheric columella (cone 5) in the central authorities of capsule, and columella (cone 5) base portion has the apophysis that slightly expands.Sporangium (spheroid 4) forms multinucleate sporangiospore.Break after sporangium (spheroid) maturation, the spore of black (salient point 6) sheds and falls within on the matrix, under suitable condition, can sprout into new mycelium.
The model teaching aid of 3-D solid structure can make the observer be well understood to outward appearance, structure and the principle of work of head mold, more be applicable to teaching explanation, and disassembly and assembly structure more is conducive to user's intensification to the cognitive and memory of head mold structure, and be conducive to packed and transported, save space and the cost of packed and transported.
