Embodiment 1

[0025] Such as Figure 1 to Figure 4 As shown, the three-dimensional space display device for mathematics teaching of the present invention includes a base plate 1, a mounting plate 2 and a three-dimensional holographic projector body 3; the three-dimensional holographic projector body 3 is fixed on the top of the mounting plate 2; the installation The plate 2 is connected to the top of the bottom plate 1 through a fixing mechanism; the fixing mechanism includes a T-shaped bar 41, a push rod 42 and a limit block 43; the top of the mounting plate 2 offers a No. 1 mounting hole 44; The top is provided with No. 2 mounting hole 45, and the diameters of No. 1 mounting hole 44 and No. 2 mounting hole 45 are the same; the T-shaped bar 41 runs through the No. 1 mounting hole 44 and the No. 2 mounting hole 45 in turn; the T-shaped bar 41 is provided with a cavity 46 inside; the top of the cavity 46 communicates with the outside world through the No. 1 hole 47; the push rod 42 is slidab...

Embodiment 2

[0034] see Figure 5 , Comparative Example 1, as another embodiment of the present invention, the bottom of the base 85 is provided with two pairs of universal wheels 10; when the device needs to be used for teaching experiments, the device can be pushed into the classroom, Then adjust the height of the three-dimensional holographic projector body 3 to carry out teaching work. The setting of the universal wheel 10 greatly facilitates the movement of the device and provides greater convenience for the teaching staff.

[0035] Working principle: when installing the 3D holographic projector body 3, first align the No. 1 installation hole 44 with the No. 2 installation hole 45, and then fully insert the bottom end of the T-shaped bar 41 into the No. 1 installation hole 44 and the No. 2 installation hole 45 , and then push the push rod 42 downward, so that the bottom end of the push rod 42 presses the stop block 43, so that the stop block 43 slides out from the second hole 48, and ...

Abstract

The invention belongs to the technical field of teaching equipment, and particularly relates to a three-dimensional space display device for mathematics teaching, which comprises a bottom plate, a mounting plate and a three-dimensional holographic projector body, the three-dimensional holographic projector body is fixedly connected to the top of the mounting plate; the mounting plate is connected to the top of the bottom plate through a fixing mechanism; the fixing mechanism comprises a T-shaped rod, a push rod and a limiting block; a first mounting hole is formed in the top of the mounting plate; a second mounting hole is formed in the top of the bottom plate, and the diameter of the first mounting hole is the same as that of the second mounting hole; the T-shaped rod sequentially penetrates through the first mounting hole and the second mounting hole; a cavity is formed in the T-shaped rod; the top of the cavity is communicated with the outside through a first hole; the three-dimensional holographic projector body can be conveniently installed; and through imaging of the three-dimensional holographic projector body, students can vividly see different three-dimensional figures.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a three-dimensional space display device for mathematics teaching. Background technique [0002] In mathematics teaching content, spatial three-dimensional graphics will be involved, and this part focuses on cultivating students' spatial imagination ability. [0003] At present, in teaching, especially in rural areas, teaching personnel generally help students understand spatial graphics by drawing on a blackboard, and this is not optimistic for students with weak spatial imagination; for this reason, the present invention provides mathematical Teaching three-dimensional space display device. Contents of the invention [0004] In order to make up for the deficiencies of the existing technology, to solve the current teaching, especially in rural areas, teaching staff generally help students understand spatial graphics by drawing on the blackboard, and this is not eff...
