Abstract

The utility model relates to a teaching aid combination, which comprises a block. A plurality of geometric bodies are inserted into the block, each of the geometric bodies can be a combination of one or more than two geometric bodies including cylinders, cones, drums and cuboids, the top faces of the geometric bodies and the top face of the block are arranged on the same horizontal plane, the top face of the block is provided with a first dovetail groove, a cover plate and the first dovetail groove are fittingly mounted so as to cover the top face of the block and the top faces of the geometric bodies. By the aid of the teaching aid combination, a plurality of geometric bodies in various types can be carried quite conveniently, and various geometric bodies required during teaching can be carried integrally when being inserted and arranged in the block. When in use of the teaching aid combination, the geometric bodies in the block can be taken out for being used independently and can also be optionally combined so as to teach visually for students according to needs, and thereby the students can visually study and master relative properties of the geometric bodies and the teaching aid combination is convenient and practical.

Description

The combined teaching method apparatus

Technical field

The utility model relates to a kind of combined teaching method apparatus.

Background technology

In conventional teaching, in the especially geometric teaching, the space of solid understanding is emphasis, difficult point to the student, often need cultivate by means of the repeatedly observation to material object for the space imagination of solid.In order to cultivate the space imagination of student to solid, teacher need demonstrate the teaching aid of solid at school the time on the classroom.When carrying a plurality of solids and give lessons, carry very inconvenient.

The utility model content

Technical problem to be solved in the utility model provides a kind of combined teaching method apparatus easy to carry.

For solving the problems of the technologies described above, the combined teaching method apparatus that the utility model provides comprises block, the some solids of plug-in mounting in the block.

For can concise description for the purpose of the problem, below combined teaching method apparatus described in the utility model be all abbreviated as this apparatus.

After adopting above technical scheme, carry a plurality of, multiple solid and become very convenient.Needed multiple geometrical body is inserted in the block in will imparting knowledge to students, and promptly can be used as an integral body and carries, and during use, as required, the solid in the block is taken out, and promptly can be used as model and does visual in image explanation for the student, and is convenient and practical.

Therefore, this apparatus have simple in structure, portably use advantage easily.

As the improvement of this device, described block is square, and the block end face has the arrangement chamber of some downward extensions, and solid places placing chamber indoor, and described solid is one or more the combination in right cylinder, cone, cylinder, the rectangular parallelepiped.

The common surface level of the end face of described solid and block end face also is provided with first dovetail groove on the end face of block, cover plate and the adaptive installation of first dovetail groove hide block end face and solid end face.

Since can with the setting of the cover plate of the adaptive installation of first dovetail groove, make to place the solid of block can arbitrarily not drop, be convenient for carrying.

As the further improvement of this device, the bottom of block has and is lower than the square horizontal counterbore of settling chamber, and plug-in mounting square body in the counterbore, this square body are pegged graft by the base plate that has second dovetail groove, with the suitable top board of second dovetail groove and formed.

In order further to improve the service efficiency of this apparatus, can also counterbore be set in the bottom of block, the base plate and the top board that are plugged in the counterbore also can be used as the solid use.

Embodiment

Below by embodiment and accompanying drawing thereof the utility model is described in further detail:

Referring to Fig. 1-Fig. 7:

The combined teaching method apparatus, comprise square block M, square block M end face has four cylindrical arrangement chambers that extend downwards, a back taper is settled chamber, settles rectangular parallelepiped 5 of right cylinder 4, suit of a cylinder 1, rectangular parallelepiped 2 of suit and a cone 3 and rectangular parallelepiped 8 of right cylinder 7, suit and right cylinder 10 that xsect is foursquare column 9 of a right cylinder 6 in four cylindrical arrangement chambers respectively; Back taper is settled and is settled a conical shell 11 in the chamber.The end face of above-mentioned each solid that places and the common surface level of square block M end face also are provided with the first dovetail groove M1 on the end face of square block M, cover plate M2 and the adaptive installation of the first dovetail groove M1 hide square block M end face and above-mentioned each solid end face.

The bottom of square block M has the square horizontal counterbore that is lower than the arrangement chamber that is opened on the top, and plug-in mounting square body in the counterbore, this square body are pegged graft by the base plate M3 that has second dovetail groove, with the suitable top board M4 of second dovetail groove and formed.

In teaching process, each solid in the utility model combined teaching method apparatus both can use separately, also each solid can be carried out arbitrary combination, helped the student to learn, grasp the related properties of solid intuitively.

Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
