Abstract

The utility model discloses a combined-type solid-geometry-teaching building block, which comprises a mother part of the block and a daughter part of the block, one or more holes of the mother part are slotted on one or more surfaces of the mother part of the polyhedral block, and one or more holes of the daughter part are slotted on one or more surfaces of the daughter part of the polyhedral block, the hole of the mother part and the hole of the daughter part are counterparts, the mother part is connected with the daughter part through a connecting device. The utility model has the advantages of simple structure, convenient manufacturing and usage, the utility model is not only played by children, but also used for the solid geometry teaching, which can help users understand and master the plane and line in the solid geometry.

Description

Assemblied stereo several teaching building blocks

Technical field

The utility model relates to a kind of teaching aid, particularly a kind ofly can commonly use the assemblied stereo several teaching building blocks that teaching aid also can be used as toy building as solid geometry.

Background technology

Present solid geometry teaching aid is various, and great majority all are that pipe fittings such as steel wire, steel pipe are spliced, and the teaching aid of this connected mode gives learner's stereoscopic sensation not strong; The toys teaching aid that adopts the solid splicing is also arranged, and it is main that such toys teaching aid is played for children again, can not play good teaching function.A kind of tetrahedron intellectual toy bricks is disclosed in the patent documentation of Chinese patent CN 85205218, it is characterized in that having spherical hole in the inside of each tetrahedron building block, in spherical hole, be placed with the magnetic steel ball, utilize the magnetic of magnetic steel ball can adsorb the building block that joins, this patented product will be placed the magnetic steel ball and comparatively bother in building block when processing and fabricating, and along with time lapse, the magnetic of steel ball can fail gradually, thereby the adsorptive power between the building block is reduced, be difficult for the combinatorial product wooden unit, the usefulness that can not well reach study, play.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of processing, easy to use is provided, and can do the toy object for appreciation and want, and can do the assemblied stereo several teaching building blocks that solid geometry is commonly used again.

The technical solution of the utility model is achieved in that a kind of assemblied stereo several teaching building blocks, comprise building block parent and building block daughter, on at least one face of polyhedron building block parent, have at least one parent slotted eye, on at least one face of every polyhedron building block daughter, have at least one daughter slotted eye, the parent slotted eye is corresponding with the daughter slotted eye, and building block parent and building block daughter flexibly connect by web member.

Described parent slotted eye and daughter slotted eye are the grooves of inner wall belt projection; Web member outer wall two ends are provided with depression, just in time cooperate with projection on parent slotted eye and the daughter slotted eye.

Described parent slotted eye and daughter slotted eye are the grooves of inner wall belt depression; Web member outer wall two ends are provided with projection, just in time cooperate with depression on parent slotted eye and the daughter slotted eye.

Described web member one end and building block daughter are one, and the other end of web member and parent slotted eye are connected.

The other end cross section of described web member is swallow-tail form, runs through a face of building block daughter; Parent slotted eye cross section is dovetail groove, runs through a face of building block parent, and web member and swallow-tail form parent slotted eye are slidingly matched.

The utility model is simple in structure, makes, easy to use, and the usefulness that can play for children also can be used as the usefulness of solid geometry teaching, helps understanding and the grasp of user to knowledge such as the face of solid geometry, lines.

Embodiment

Below in conjunction with accompanying drawing the utility model further is explained in detail.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of assemblied stereo several teaching building blocks, comprise building block parent 1 and building block daughter 2, on polyhedron building block parent 1 at least one face, have at least one parent slotted eye 1.1, on every polyhedron building block daughter 2 at least one face, have at least one daughter slotted eye 2.2, parent slotted eye 1.1 is corresponding with daughter slotted eye 2.2, and building block parent 1 flexibly connects by web member 3 with building block daughter 2.

Shown in Fig. 1, Fig. 4 a, Fig. 4 b, parent slotted eye 1.1 and daughter slotted eye 2.2 are grooves of inner wall belt projection; Web member 3 outer wall two ends are provided with depression, just in time cooperate with projection on parent slotted eye 1.1 and the daughter slotted eye 2.2.The also groove of inner wall belt depression of parent slotted eye 1.1 and daughter slotted eye 2.2 in like manner; Web member 3 outer wall two ends are provided with projection, just in time cooperate with depression on parent slotted eye 1.1 and the daughter slotted eye 2.2.

Shown in Fig. 2, Fig. 4 b, Fig. 4 c, web member 3 one ends and building block daughter 2 are one, and the other end of web member 3 and parent slotted eye 1.1 are connected.

Shown in Fig. 2, Fig. 4 c, the other end cross section of web member 3 is swallow-tail form, runs through a face of building block daughter 2; Parent slotted eye 1.1 cross sections are dovetail groove, run through a face of building block parent, and web member 3 is slidingly matched with swallow-tail form parent slotted eye 1.1.

Structure of the present utility model is not limited only to the positive tetrahedron shown in the accompanying drawing, is equally applicable to polyhedrons such as cone, right cylinder.
