Abstract

The utility model belongs to the technical field of teaching aids and discloses an assembled solid geometry demonstrator, which comprises more than three spherical connectors and more than one group of connecting rods which are connected with the spherical connectors in a matching mode, wherein the spherical connectors are connecting convex columns or blind holes which are radially and uniformly distributed in the outer surface of a sphere and are integrally molded with the sphere; the connecting rods can be connected with the connecting convex columns or blind holes on the spherical connectors in a matching mode; and each group of connecting rods has different lengths and consists of more than six connecting rods. The spherical connectors are matched with the connecting rods, solid geometry frames in different forms can be vividly, visually and intuitively assembled, and molecular three-dimensional structure graphs in chemistry can be connected; and moreover, the assembled solid geometry demonstrator can serve as a toy for children, so that the solid geometry concept and space imagination of the children are cultivated from childhood.

Description

Pin-connected panel solid geometry demonstration device

Technical field

The utility model belongs to the teaching aid technical field, refers in particular to a kind of pin-connected panel solid geometry demonstration device.

Background technology

At present, the student who begins to learn solid geometry always feels that the study of solid geometry is too difficult, manages unclear thinking of solving a problem; Can not find the method for solving a problem, trace it to its cause: the one, Most students lacks space imagination, particularly schoolgirl; Student's space imagination ought to begin to cultivate training from little; Various building blocks, magic square, paper folding etc. are movable cultivates but this training is mainly through playing, and it is recreational that these toys lay particular emphasis on, and lacks the cultivation to space imagination; On the other hand, the teacher be difficult to the concept of space of solid geometry on the blackboard on plane, draw clear, say clearly, student oneself does not make up the experiment equipment of solid geometry again, confession can be levied down the usefulness of doing it yourself to assemble, study, understand solid geometry.

Summary of the invention

The purpose of the utility model provides a kind of pin-connected panel solid geometry demonstration device that freely forms the space geometry body.

The purpose of the utility model is achieved in that

Pin-connected panel solid geometry demonstration device; Comprise the ball-type connector more than three and cooperate the connecting rod more than a group of pegging graft with the ball-type connector; Described ball-type connector is that the outside surface at spheroid is and radioactively is evenly equipped with and integrated projection or the blind hole of being connected of spheroid; Described connecting rod be can with the ball-type connector on be connected the connecting rod that projection or blind hole cooperate socket connection, every group of connecting rod has different length and every group of connecting rod is made up of the connecting rod more than the six roots of sensation.

Above-mentioned spheroid is spheroid or spherosome.

Above-mentioned connection projection or blind hole have more than 16.

Above-mentioned spheroid and connection projection are processed with plastic material or elastomeric material.

The utility model is compared the outstanding and beneficial technical effects of prior art:

1, the utility model can be by different solid geometry frameworks connecting rod on pegging graft on the connection projection of ball-type connector or the blind hole; Can be assembled into the solid geometry framework of different shape; Utilize this solid geometry framework to see at an easy rate solid geometry characteristic and the known conditions that will solve a problem and position or the angular relationship of being asked object, lively, image, directly perceived.

2, the utility model cooperates with the ball-type connector with connecting rod and can connect into solid geometry teaching aid, also can connect into the molecule stereo structure figure in the chemistry, can also be as toy for children, from little cultivation children's solid geometry notion and space imagination.

Description of drawings

Fig. 1 is the utility model schematic perspective view.

Fig. 2 is the cut-open view that is connected the connecting rod of usefulness with any corner connector of the utility model.

Fig. 3 is the schematic perspective view of the solid geometry that connects into six any corner connectors, nine connecting rods.

Embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:

Pin-connected panel solid geometry demonstration device; Comprise the ball-type connector 1 more than three and cooperate the connecting rod more than a group 2 of pegging graft with ball-type connector 1; Described ball-type connector 1 is that the outside surface at spheroid 11 is and radioactively is evenly equipped with and spheroid 11 integrated projection 12 or the blind holes of being connected; Described connecting rod 2 be can with the ball-type connector on be connected the connecting rod 2 that projection 12 or blind hole cooperate socket connection, every group of connecting rod has different length and every group of connecting rod is made up of the connecting rod more than the six roots of sensation 2, that is to say: each length of organizing connecting rod is identical; But has different length between every group of connecting rod; So that the solid geometry frame model of assembling different size, for example: the equal in length on the limit of a positive body, but it is long to connect the length of its cornerwise hypotenuse.

Above-mentioned spheroid 11 is spheroid or spherosome.

Above-mentioned connection projection 12 or blind hole have more than 16, and this can confirm according to the surface area of spheroid 11, generally will make connection projection 12 or blind hole more than 32; Can realize the connection of a plurality of stereoscopic models; To realize the interest of playing by children, connection projection 12 or blind hole on the spheroid 11 are many more, and the position that can supply peg graft is just many more; In fact the outside surface of spheroid 11 has been covered with connection projection 12; So that at the arbitrarily angled grafting connecting rod of spheroid 11, be assembled into the solid geometry body of any needs, the authenticity of demonstration is high more, the interest of playing by children is big more.

Above-mentioned spheroid 11 and connection projection 12 usefulness plastic materials or elastomeric material are processed, and the production cost of plastic material or elastomeric material is low, is convenient to the moulding manufacturing.

The utility model not only cooperates with connecting rod can be assembled into single space multistory geometric Framework; Can also a plurality of space multistory geometric Framework be dressed up a framework that has a plurality of space multistory solids with connection rod set; Increased recreational; Can further improve child or student's space imagination, also can connect into the three-dimensional structure diagram of the molecule in the chemistry with connecting rod, vivid.

The foregoing description is merely the preferred embodiment of the utility model, is not the protection domain that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection domain of the utility model.
