Abstract
The utility model discloses a solid geometry demonstration teaching appliance which is used for solving the demonstration problem of molecular solid structure or molecular biological structure in classrooms. The solid geometry demonstration teaching appliance comprises a member and a connecting rod. The solid geometry demonstration teaching appliance is characterized in that the member is made of a soft-magnetic material; two ends of the connecting rod are provided with magnetic substances; and the surfaces of the magnetic substances at two ends of the connecting rod are provided with concave surfaces. Compared with the prior art, the solid geometry demonstration teaching appliance can mobilize the positivity of students in the classroom, has strong practicability and wide application scope, can be disassembled and assembled conveniently, has small storage volume, can be freely assembled to form microstructure models of different substances, and can be multifunctional, therefore, the cost is saved.
Description
[technical field]
The utility model relates to a kind of mathematics teaching aid, relates in particular to a kind of demonstration teaching aid that is applicable to that solid geometry teaching is used.
[background technology]
Solid geometry teaching is a very important course in the mathematics class teaching of senior high school period, but also is simultaneously that a teacher is not easy blunt explanation, student and is not easy the course understood rapidly.Such a case often appears, to a certain how much topics, the teacher thinks that from the space imagination that it had explained fully aware of understand, but because the student in this stage does not still possess stronger space imagining ability, it is comparatively fuzzy to the three-dimensional imagination, understanding, thereby all brings certain difficulty for the learning aid of solid geometry.This problem solves bad, must influence grasp degree and learning interest and the confidence of student to three-dimensional geometric knowledge.Address this problem, ideal method just is to use teaching aid.The solid geometry teaching aid and the demonstration equipment thereof of ordinary secondary school's use at present, its purposes is more single, perhaps uses inconvenience, and structure is also comparatively complicated.
[utility model content]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of solid geometry demonstration teaching aid is provided, with the problem of the point, line, surface in the solution several teaching and position relation and the demonstration of multiple solid.
The technical scheme in the invention for solving the technical problem is: a kind of solid geometry demonstration teaching aid is characterized in that: comprise connecting link, joint ball and joint; Described connecting link one end is a projection, and an end has depression, and described joint ball is a magnetic conductive metal; Described joint comprises convex joint and female fitting, and described convex joint is cylindrical, the end material that is magnetic, and the other end has projection, and described female fitting is cylindrical, the end material that is magnetic, the other end has depression; Between the described connecting link, and can be connected by concavo-convex between connecting link and the joint.
The magnetic conductive metal of above-mentioned joint ball is a magnetic stainless steel.
The magnetisable material of above-mentioned joint one end is a magnet steel.
Above-mentioned connecting link and joint surface are coated with different colours plastics or plastic coating respectively except that position, magnetisable material place.
Compared with prior art, the utility model advantage is to make the making scope of solid geometric pattern to increase greatly, utilize the combination of pegging graft arbitrarily of connecting link, joint ball and joint, can be combined into solid geometric patterns such as polyhedron, enlarge the student in the idea of understanding aspect the solid geometry space, lively directly perceived, further cultivate student's knowledge figure ability, can satisfy Faculty and Students substantially and when solid geometry teaching, use.
[description of drawings]
Fig. 1 is the structural representation of connecting link of the present utility model;
Fig. 2 is the synoptic diagram of the utility model demonstration rectangular parallelepiped.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
The utility model comprises several connecting links 1, joint ball 3 and joint 2.
As shown in Figure 1, described connecting link 1 one ends are that projection 11, one ends have depression 12.
Described joint ball 3 is a magnetic conductive metal, and preferred plan is magnetic stainless steel, more easily is magnetized.
Described joint 2 comprises convex joint and female fitting, and described convex joint is cylindrical, the end material that is magnetic, and the other end has projection, and described female fitting is cylindrical, the end material that is magnetic, the other end has depression.Described magnetisable material can be magnet steel.
Connecting link 1 and joint 2 surfaces are coated with different colours plastics or plastic coating respectively except that position, magnetisable material place.
Between the described connecting link 1, and can be connected by concavo-convex between connecting link 1 and the joint 2.
As shown in Figure 2, connecting link 1 is concavo-convex to connect and compose rectangular limit, the concavo-convex joint 2 that is connected with in the two ends on limit, and joint 2 is connected with joint ball 3 by magnetisable material separately.The above builds rectangular parallelepiped.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all contained by claim of the present utility model.
Claims (4)
