Abstract

The invention belongs to the field of three-dimensional geometric teaching tools, and relates to a three-dimensional geometric LED (light emitting diode) quick molding teaching tool. The three-dimensional geometric LED quick molding teaching tool comprises a geometric molding device and a control device, wherein the geometric molding device and the control device are connected by a conducting wire; the geometric molding device comprises a circular base and an LED molding mechanism, and the LED molding mechanism is arranged on the circular base; the LED molding mechanism comprises an LED light tube circular ring base, an LED light emitting tube circular disc, an LED lamp tube assembly and a circular ring connecting assembly, the LED light tube circular ring base is arranged in the circular base, the LED light emitting tube circular disc is arranged at the inner side of the LED lamp tube circular ring base, the LED lamp tube assembly is arranged on the LED lamp tube circular ring base, and the circle connecting assembly is arranged at the top part of the LED lamp tube assembly. The three-dimensional geometric LED quick molding teaching tool has the advantages that the structure is simple, the convenience in use is realized, and the space imagination ability, three-dimensional feel and motivation of children are greatly improved.

Description

technical field [0001] The invention belongs to the field of three-dimensional geometry teaching aids, and relates to a three-dimensional geometry LED rapid prototyping teaching aid. Background technique [0002] At present, the teaching aids used in the teaching of solid geometry mostly use wooden molds or plastic models. One kind of geometry needs to be made into one model, and several kinds of geometry need to be made into several models. In order to show the internal spatial structure of the geometry, such as figure 1 and figure 2 As shown, the frame bar 21 is used as the ridge line of the geometric body to make a geometric wire frame model such as a quadrilateral body or a triangular body. [0003] These three-dimensional geometry teaching aids have played a certain role in teaching, but there are also some shortcomings: one is that a model can only display one geometric shape, and the versatility is poor. When teaching, the number of models that teachers bring to the...

Problems solved by technology

[0003] These three-dimensional geometry teaching aids have played a certain role in teaching, but there are also some shortcomings: one is that a model can only display one geometric shape, and the versatility is poor. When teaching, the number of models that teachers bring to the classroom is relatively small Many, large volume, not easy to carry; second, it is impossible to visually display the body diagonal and face diagonal of the geometry

[0004] In addition, the teaching aids used in the current three-dimensional geometry teaching are single, which is of little help to improve students' abstract thinking ability

The existing teaching aids are basically welded with iron frames or assembled with plexiglass, which are large in number and do not fully demonstrate the internal relationship after the three-dimensional geometric transformation
