Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, in particular to a primary school mathematics geometry figure demonstration platform. Background Art

[0002] Mathematics is a universal means for humans to strictly describe the abstract structure and pattern of things. It can be applied to any problem in the real world. All mathematical objects are essentially defined by humans. In the process of learning mathematics, the acceptance and understanding of teaching knowledge is related to the cultivation of their interest and the cultivation of learning initiative. Demonstration teaching aids can transform abstract mathematical knowledge into a visual structure to help students understand and learn.

[0003] Similar mathematical geometry demonstration teaching aids have also appeared in the prior art; for example, the patent with application number 2021214380660 discloses an elementary school mathematical geometry demonstration platform, including a two-dimensional graph teaching component and a three-dimensional graph teaching component, the two-dimensional graph teaching component includes a support frame, a symmetrical stabilizing rod runs through the support frame, a two-dimensional graph demonstration board is fixed between the two stabilizing rods, and the three-dimensional graph teaching component includes an adjustment disk, an adjustment frame and a second storage slot, an angle positioning hole is provided on the side of the adjustment disk, a steering rod runs through the adjustment disk, a bearing is provided at the connection between the steering rod and the adjustment disk, and a magnetic rod is connected to the lower end of the adjustment frame, a special-shaped demonstration block is magnetically attracted on the surface of the magnetic rod, and a magnetic hole runs through the top of the special-shaped demonstration block. The above technical scheme can perform two-dimensional and three-dimensional geometric figure displays, which is convenient for teaching;

[0004] However, the above technical solution also has certain defects: the structure is relatively complex and inconvenient to use. Secondly, it cannot display three-dimensional geometric bodies in multiple ways, but can only be displayed in a fixed manner, which is not conducive to students' understanding of geometric bodies; and it cannot allow students to manually operate and use geometric bodies to stack games, which is not conducive to students' understanding of the combination of geometric bodies.

[0018] 2. The flat plate is provided with a plate body all around, and the upper end surface of the plate body and the lower end surface of the flat plate are connected by hinges, so that when the plate body is rotated to a horizontal state, the side of the plate body is against the side of the flat plate, so that the plate body remains in a horizontal state, so that a relatively large platform can be unfolded on the flat plate, which is convenient for students to take geometric bodies and stack them on it, and freely combine them like building blocks, so as to develop students' brains and help students understand the combination of geometric bodies with each other; and when the plate body is erected, it can form a box with the flat plate, which can be used to store items;

[0040] A mounting hole 207 is provided at the bottom of the storage box 201 and at a position corresponding to the spring 203. The bottom of the round rod 205 is inserted into the mounting hole 207. The mounting hole 207 limits the round rod 205 so that the round rod 205 is in a vertical state. The spring 203 gives the round rod 205 a downward force so that the round rod 205 is pressed against the bottom of the mounting hole 207 to prevent it from running out of the mounting hole 207.

[0041] The geometric body 300 is provided with a through hole 301 penetrating the geometric body 300 along the midline. The geometric body 300 is sleeved on the round rod 205 through the through hole 301 and can rotate on the round rod 205.

When the upper end of the octagonal column 104 moves out of the octagonal hole 102, the rod body 105 can be rotated 90 degrees to make the rod body 105 and the base frame 100 parallel for storage. The upper end of the T-shaped cylinder 103 will rest on the step inside the T-shaped circular hole 101 to prevent the rod body 105 from detaching from the base frame 100.

At this time, the side of the plate 209 will be against the side of the flat plate 202, thereby maintaining a horizontal state. Then, the geometric objects 300 can be stacked or displayed on the platform formed by the plate 209 and the flat plate 202.
