Abstract

The utility model relates to a teaching aid or a toy. A rotary spilt is hinged by a right triangular prism, wherein the bottom surface of the right triangular prism is an isosceles right triangle, and the side surfaces of the right triangular prism can be rotatably hinged pairwise. The rotary spilt has the advantages of simpleness in construction and low cost, and provides a toy which applies the geometric knowledge. The imagery thinking of children can be cultured by practice and thought, the memory ability is trained, and the level of intelligence is improved.

Description

The rotation piece

Technical field

The utility model relates to teaching aid or toy, and particularly a kind of rotation piece of suitable study plane geometry can make the teacher have a kind of effective instrument to make the student use the geometric knowledge of learning after school, and use one's hands and brains.Through the memory capability of training of students, cultivate thinking in images, excite potential innovation ability.

Background technology

Along with the people in modern living standard improves; Diversity and requirement for toy also improve, and need on higher knowledge aspect, carry out amusement, for adapting to this variation; Said rotation piece can address this problem; Seem simple, piece together the brains that still will make a motion, can reach the purpose that uses one's hands and brains.

Summary of the invention

In order to solve the apparatus problem that people use one's hands and brains, the utility model provides a kind of rotation piece according to topological geometric knowledge, can make people through using one's hands and brains, and cultivates thinking in images, and the training memory capability improves intellectual level.

The scheme that the utility model adopted is:

The rotation piece forms by straight triangular prism is hinged, and the bottom surface of said straight triangular prism is an isosceles right triangle, and a side of said straight triangular prism is rotatable in twos hinged.Be combined into 3 * 4 or 2 * 5 rectangle when choosing 24 said straight triangular prisms when hinged, can rotating, the said straight triangular prism that also can choose varying number is hinged, is combined into the different rectangle of size, or other elephant shaped object.Said straight triangular prism is a moulding, adopts disposable barb to be pressed into assembling, and it is on-dismountable voluntarily to piece together the player after the assembling, helps the globality of toy for children, avoids dissipating and loses, and uses durable.

The beneficial effect of the utility model is:

Rotation tile configuration simple cost is low, and a kind of toy of applicating geometric knowledge is provided, and it is many to be combined into figure, leaves the leeway of people's imagination for.Be fit to rigidly connect the child who touches plane geometry knowledge and piece together object for appreciation, can be combined into other elephant shaped object, said elephant shaped object is freely assert by child, oneself thinks what what is exactly as, obtains training again outside the enjoyment memory capability.

Description of drawings

Figure below in conjunction with the utility model further specifies:

Fig. 1 is said straight triangular prism sketch map;

Fig. 2 is two said straight triangular prisms sketch mapes when hinged;

Fig. 3 is 24 said straight triangular prisms sketch mapes when hinged;

Fig. 4 is 2 * 5 rectangle sketch mapes;

Fig. 5 is 3 * 4 rectangle sketch mapes.

Among the figure, the 1. bottom surface of said straight triangular prism, 2. a side of said straight triangular prism.

The specific embodiment

Like Fig. 1 is said straight triangular prism sketch map, and the bottom surface of said straight triangular prism (1) is isosceles right triangle, and a side (2) of said straight triangular prism is rotatable in twos hinged, and said rotation piece is by hinged the forming of said straight triangular prism.

Like Fig. 2 is two said straight triangular prisms sketch mapes when hinged, and promptly side and side are hinged.

Like Fig. 3 is 24 said straight triangular prisms sketch mapes when hinged, promptly said rotation piece product sketch map.

Like Fig. 4 is 2 * 5 rectangle sketch mapes, is hinged to said rotation piece by 24 said straight triangular prisms and is combined into.

Like Fig. 5 is 3 * 4 rectangle sketch mapes, is hinged to said rotation piece by 24 said straight triangular prisms and is combined into.

One side of said straight triangular prism is rotatable in twos hinged, be meant can 360 the rotation of degree, can rotate to certain position as required.

Claims

1. a rotation piece forms by straight triangular prism is hinged, and it is characterized in that: the bottom surface of said straight triangular prism (1) is isosceles right triangle, and a side (2) of said straight triangular prism is rotatable in twos hinged.
