Problems solved by technology

[0004] There are many types of display in mathematical three-dimensional space. The present invention is based on the spatial imagination of cube or cuboid expansion, and provides students with pictures that help to imagine its expansion. The expansion of cubes can be divided into 11 types, and this The expansion model is reflected in the test papers of elementary school, junior high school, high school, university, Olympiad test papers, and even civil service examination papers, but the degree of difficulty is different, and it is more helpful for students to improve their spatial imagination. When answering these kinds of test questions, they rely on spatial imagination or plane drawing to demonstrate. There is no real object to provide a theoretical basis for it, and it is impossible to intuitively touch and observe its unfolded form.
[0005] For example, if there is a point in the cube in the test question, what form will the point be displayed in when it is unfolded, or how the ant can reach the goal in the shortest distance after the cube is unfolded, etc., all test the shape of the cube unfolded, and the market There is no such device in the world that can specifically display the shape of the cube after unfolding

Embodiment 1

[0035] Embodiment 1, the present invention is a three-dimensional space display device for mathematics teaching, comprising an inner frame 1, a lower plate 2 and an unfolded plate 3, the lower plate 2 is installed at the bottom of the inner frame 1, and the lower plate 2 is connected to the expanded plate 3; the lower plate 2 and the structure formed by the expansion plate 3 wraps the inner frame 1 inside;

[0036] Expanding plate 3 comprises right side panel 31, left side panel 32, front side panel 33, top panel 34 and rear side panel 35; As each face of the hexahedron, the side panel 35 can be unfolded and combined according to the needs of use, which is convenient for the teacher to explain and use;

[0037] The lower plate 2 and the right side panel 31, the lower plate 2 and the left side panel 32, the lower plate 2 and the front side panel 33 are all connected by the first unfolding power structure 4, and the front side panel 33 and the top plate 34 are connected by the s...

Embodiment 2

[0038] Embodiment 2, on the basis of Embodiment 1, there are openings 11 in the inner frame 1 corresponding to the first deployment power structure 4, the second deployment power structure 5 and the third deployment power structure 6, so that the first deployment power structure The power structure 4, the second deployment power structure 5 and the third deployment power structure 6 will not affect the overall closure.

Embodiment 3

[0039] Embodiment 3. On the basis of Embodiment 1, the first deployment power structure 4 includes an outer tube 41 installed on the lower plate 2. The inner tube 41 of the outer tube 41 is slidably connected with an inner tube 42 for connecting and fixing with other plates. The outer tube The bottom end of the inner chamber of 41 is connected with the inner tube 42 through a spring one 43, and the outer tube 41 and the inner tube 42 are correspondingly equipped with a clamping platform 44, which can prevent the connection between the outer tube 41 and the inner tube 42 from being separated.

Abstract

The invention relates to the technical field of mathematics, and particularly relates to a three-dimensional space demonstration device for mathematical education, effectively solving the problem of linkage between points, lines and planes, and thus facilitating explanation of teachers and understanding of students. The specific technical scheme is as follows: the device comprises an inner frame,a lower plate and an expansion plate, wherein the lower plate is installed at the bottom end of the inner frame, and the lower part is connected with the expansion plate; the expansion plate comprisesa right side plate, a left side plate, a front side plate, a top plate and a rear side plate; the lower plate is respectively connected with the right side plate, the left side plate and the front side plate via first expansion power structures; the front side plate and the top plate are connected with a second expansion power structure; one end of the rear side plate is detachably connected withthe top plate via a third expansion power structure; the other end of the rear side plate is also detachably connected with the lower plate via a third expansion power structure; and an auxiliary expansion and closing structure is installed on the lower plate in the inner frame.

Description

technical field [0001] The invention relates to the technical field of mathematics, in particular to a three-dimensional space display device for mathematics teaching. Background technique [0002] The concept of space is the basic condition for cultivating students' innovative spirit, and it is also one of the current mathematics teaching. With the continuous deepening of the new course teaching, how to cultivate students' space concept has become an important goal of mathematics education. [0003] The imagination of mathematical space has always been difficult. It tests the spatial thinking ability of people's brains. If the spatial imagination ability is relatively weak, it often needs to rely on real objects for assistance. [0004] There are many types of display in mathematical three-dimensional space. The present invention is based on the spatial imagination of cube or cuboid expansion, and provides students with pictures that help to imagine its expansion. The expan...
