Abstract
The utility model relates to a folding-type cube model. The folding cube model is composed of frames, connecting rods, fixing sleeves and screws; two frames exist, and the upper end and the lower end of the external side of each vertical straight edge of the frames are provided with holes and the screws; eight connecting rods exist, and two ends of each connecting rod are provided with holes and screws; and the fixing sleeves sleeve the connecting rods. Teachers and students can learn solid geometry more easily by means of the solid frame structure of the folding-type cube model itself; and the folding-type cube model can be folded, and therefore, storage space can be saved. Thus, the folding-type cube model has the advantages of simple structure, convenient use and high practicability.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of folding cubic body Model.
Background technology
Teaching aid is the general name of the apparatus that uses while making student can understand intuitively, visually each appliances that the content of courses uses and teachers' instruction, is called for short teaching aid.Teaching aid can improve student's learning interest, enriches perceptual knowledge, and helps to form clear and definite concept, the observation ability of Developing Students ' and thinking ability.General point common teaching aid, special teaching aid and Teachig-aid for infant studying three classes, comprise picture, material object, model etc.
In the time of study solid geometry, teacher is difficult to draw on the blackboard of plane the figure that stereoscopic sensation is very strong and out imparts knowledge to students, and a lot of classmates also cannot produce three-dimensional sensation, have to explain by the material object of similar structure in real life.And existing material object can not be with entering classrooms at any time, when explanation, student is by ordinary times to understanding in kind and then understand the content that teacher explains.Such teaching teacher explains very effort, and Students ' Learning gets up also gruelling, makes troubles to learning life.
Utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of this utility model is to provide a kind of folding cubic body Model, its adopts in upper and lower four positions, outside of every vertical edge of framework the correspondence position of being fixed one group of connecting link and be connected to another one framework by screw, every group of connecting link is fixedly connected with by screw by two connecting links, connecting link can be around screw turns, fixed cover is enclosed within on connecting link, the junction of fixing every group of connecting link, and then spatial structure is fixed.
In order to realize the technical scheme that the purpose of this utility model adopts be: a kind of folding cubic body Model, is characterized in that: it is made up of framework, connecting link, fixed cover, screw; Described framework is square body, has two, and the upper and lower two ends, outside of every vertical edge are provided with hole and screw; Described connecting link has eight, and two ends are equipped with hole and screw; Described fixed cover is circular, is enclosed within on connecting link.
The beneficial effects of the utility model are: it can either utilize self space frame structure, allow the easier study solid geometry of teachers and students, can fold again, save parking space; And simple in structure, easy to use, practical.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model structural drawing
Fig. 2 is the utility model connecting link structural drawing when inwardly folding
Fig. 3 is the utility model connecting link structural drawing when folded-out
1-framework, 2-connecting link, 3-fixed cover, 4-screw in figure.
Embodiment
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, a kind of folding cubic body Model, is characterized in that: it is made up of framework, connecting link, fixed cover, screw; Described framework is square body, has two, and the upper and lower two ends, outside of every vertical edge are provided with hole and screw; Described connecting link has eight, and two ends are equipped with hole and screw; Described fixed cover is circular, is enclosed within on connecting link.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, described connecting link one end is fixed on frame vertical straight limit by screw, the other end is connected with the connecting link of correspondence position on another one framework by screw, can be around screw turns, every two form one group of four position up and down that are separately fixed at two vertical edges of framework, with system framework spatial structure, be convenient to learn solid geometry; Described fixed cover moves to the junction of two connecting links, fixes two connecting links and is horizontal, and makes spatial structure indeformable.
While using the utility model, first every connecting link two are screwed, then each group connecting link is screwed respectively to four positions up and down at two vertical edges of framework, finally fixed cover is moved to the junction of two connecting links, connecting link is all horizontal, and spatial structure is fixing; In explanation when figure, can be according to figure bracing wire in spatial structure, allow the student can clearer study solid geometry; After finishing using, can, by inside connecting link or folded-out depositing, save space.
Claims (3)
