Technical Field

[0001] This utility model relates to the field of teaching aids technology, and in particular to a teaching aid for mathematical modeling. Background Technology

[0002] Mathematical modeling is an important means of solving practical problems using mathematical tools. In order to reduce the difficulty of modeling mathematical concepts, rules and problem-solving methods, and make it easier for students to master relevant mathematical knowledge, teachers need to make good use of various related teaching aids.

[0003] A search revealed that utility model patent CN216211735U discloses a mathematical modeling demonstration teaching aid, including a box, an adjustment and positioning component, and a demonstration component. The adjustment and positioning component is located inside the box, and the demonstration component is located inside the box. The adjustment and positioning component includes an adjustment column, a main demonstration board, a fixed column, a protrusion, a positioning plate, and a fixing block. The demonstration component includes a fixed plate, a horizontal plate, a forward and reverse motor, a drive gear, a positioning column, an adjustment rod, a driven gear, a sleeve, an auxiliary demonstration board, and a support rod.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when unfolding and storing the display components, teachers need to go through a rather cumbersome operation, which wastes time and is not convenient in actual use.

[0005] Therefore, it is necessary to invent a teaching tool for mathematical modeling to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a teaching tool for mathematical modeling that can more conveniently unfold and store the demonstration teaching mechanism. It is simple to operate, saves manpower and time, and has a better practical effect. This solves the problem mentioned in the background art that when unfolding and storing display components, teachers need to go through a relatively cumbersome operation, which wastes time and is not convenient to use in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a teaching aid for mathematical modeling, comprising:

[0008] A storage mechanism, wherein the storage mechanism is used to store the demonstration and teaching equipment;

[0009] Demonstration teaching apparatus, wherein the demonstration teaching apparatus is used to display the drawn mathematical model; and

[0010] An unfolding locking mechanism is provided, comprising a rotating shaft, an end plate, a torsion spring, a T-shaped locking rod, and a return spring.

[0011] The rotating shaft passes through the inside of the storage box and is rotatably connected to the storage box via a bearing. There are two end plates and two torsion springs. The two end plates are fixedly installed at both ends of the rotating shaft, and the two torsion springs are respectively sleeved at both ends of the outside of the rotating shaft. The torsion springs are fixedly connected between the outer wall of the storage box and the adjacent end plates. The T-shaped locking rod is slidably installed through the center of the front of the storage box and slidably installed inside the handle. The end of the T-shaped locking rod near the rotating shaft is provided with an inclined surface. The return spring is sleeved on the outside of the T-shaped locking rod and is fixedly connected between the outer wall of the storage box and the T-shaped locking rod.

[0012] According to at least one embodiment of the present disclosure, the teaching aid for mathematical modeling includes a storage mechanism comprising a storage box and a handle, wherein the handle is fixedly disposed in the center of the front of the storage box.

[0013] According to at least one embodiment of the present disclosure, a teaching aid for mathematical modeling includes a main demonstration board and a locking groove. The main demonstration board is fixedly sleeved on the middle of the outer side of the rotating shaft, and the locking groove is opened at the middle of the top of the main demonstration board.

[0014] According to at least one embodiment of the teaching aid for mathematical modeling of the present disclosure, the demonstration teaching mechanism further includes a secondary display board and a traction board, and two secondary display boards and two traction boards are provided. The two secondary display boards are slidably nested on both sides of the main demonstration board, and the two traction boards are fixedly provided at the ends of the two secondary display boards away from the main demonstration board.

[0015] According to at least one embodiment of the teaching aid for mathematical modeling of the present disclosure, the demonstration teaching mechanism further includes a first magnet and a second magnet, wherein the first magnet is fixedly nested on the top of the main demonstration board and the second magnet is fixedly nested on the top of the traction plate.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features an unfolding and locking mechanism. When the demonstration and teaching mechanism needs to be unfolded, the T-shaped locking rod is pulled outward while holding the handle. The pulled T-shaped locking rod stretches the return spring, and its end moves out of the locking groove. At this time, the stored torsion spring drives the rotating shaft to rotate via the end plate. The rotating shaft causes the demonstration and teaching mechanism to rotate synchronously, thus changing the mechanism from a horizontal storage state to a vertical display state. When the demonstration and teaching mechanism is subsequently stored, the main demonstration board is rotated around the rotating shaft. During rotation, the main demonstration board contacts the inclined surface of the T-shaped locking rod end, pushing the T-shaped locking rod. When the demonstration and teaching mechanism rotates to a horizontal position, the stretched return spring causes the T-shaped locking rod to insert into the locking groove, completing the locking of the demonstration and teaching mechanism. Compared with existing similar devices, this invention allows for more convenient unfolding and storage of the demonstration and teaching mechanism, is simple to operate, saves manpower and time, and has better practical effects.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a teaching aid for mathematical modeling according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the storage mechanism 1 and the unfolding locking mechanism 3 of a teaching aid for mathematical modeling according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the structure of a demonstration teaching apparatus 2 for mathematical modeling teaching aids according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the teaching aids for mathematical modeling disclosed herein may include components such as a storage mechanism 1, a demonstration teaching mechanism 2, and an unfolding and locking mechanism 3.

[0031] like Figure 2 As shown in the present disclosure, the storage mechanism 1 includes a storage box 11 and a handle 12, wherein the handle 12 is fixedly disposed in the center of the front of the storage box 11.

[0032] This allows the storage box 11 to be lifted and moved using the handle 12.

[0033] like Figure 3As shown, in a preferred embodiment, the demonstration teaching mechanism 2 includes a main demonstration board 21, a locking groove 22, a secondary display board 23, a traction plate 24, a first magnet 25, and a second magnet 26. The main demonstration board 21 is fixedly sleeved on the middle of the outer side of the rotating shaft 31. The locking groove 22 is opened at the middle of the top of the main demonstration board 21. There are two secondary display boards 23 and two traction plates 24. The two secondary display boards 23 are slidably nested on both sides of the main demonstration board 21. The two traction plates 24 are fixedly installed at the ends of the two secondary display boards 23 away from the main demonstration board 21. The first magnet 25 is fixedly nested on the top of the main demonstration board 21, and the second magnet 26 is fixedly nested on the top of the traction plate 24.

[0034] Therefore, it is convenient to draw mathematical models on the front of the locking slot 22 and the front of the secondary display board 23 before the start of class, so that they can be directly displayed in class and avoid having to draw them on the spot in class, thereby improving teaching efficiency. In addition, when the main display board 21 is in a horizontal storage state and the secondary display board 23 is inside the main display board 21 and not pulled out, the main display board 21 can protect the mathematical models drawn on the secondary display board 23, and the storage box 11 can protect the mathematical models drawn on the main display board 21.

[0035] When the teacher needs to unfold the secondary display board 23, he can pinch the pull plate 24 and then pull the pull plate 24 away from the main display board 21, thereby separating the second magnet 26 from the first magnet 25. At this time, the secondary display board 23 gradually moves out of the main display board 21 under the action of the pull plate 24.

[0036] like Figure 2 As shown in this disclosure, the unfolding locking mechanism 3 includes a rotating shaft 31, an end plate 32, a torsion spring 33, a T-shaped locking rod 34, and a return spring 35. The rotating shaft 31 is disposed through the inner side of the storage box 11 and is rotatably connected to the storage box 11 via a bearing. Two end plates 32 and two torsion springs 33 are provided. The two end plates 32 are respectively fixedly disposed at both ends of the rotating shaft 31, and the two torsion springs 33 are respectively sleeved at both ends of the outer side of the rotating shaft 31. The torsion springs 33 are fixedly connected between the outer wall of the storage box 11 and the adjacent end plate 32. The T-shaped locking rod 34 is slidably disposed through the center of the front of the storage box 11 and is slidably disposed inside the handle 12. The end of the T-shaped locking rod 34 near the rotating shaft 31 is provided with an inclined surface. The return spring 35 is sleeved on the outer side of the T-shaped locking rod 34 and is fixedly connected between the outer wall of the storage box 11 and the T-shaped locking rod 34.

[0037] Therefore, when the demonstration teaching mechanism 2 needs to be unfolded, the T-shaped locking rod 34 is pulled outward while holding the handle 12. After the T-shaped locking rod 34 is pulled, it stretches the return spring 35, and its end moves out from the inside of the locking groove 22. At this time, the energy-stored torsion spring 33 drives the rotating shaft 31 to rotate through the end plate 32. When the rotating shaft 31 rotates, it drives the demonstration teaching mechanism 2 to rotate synchronously, thereby changing the demonstration teaching mechanism 2 from a horizontal storage state to a vertical display state. When the demonstration teaching mechanism 2 is subsequently stored, it is directly rotated... The rotating shaft 31 rotates around the main demonstration board 21. During the rotation, the main demonstration board 21 contacts the inclined surface at the end of the T-shaped locking rod 34 and pushes the T-shaped locking rod 34. When the demonstration teaching mechanism 2 rotates to a horizontal state, the stretched return spring 35 drives the T-shaped locking rod 34 to insert into the locking groove 22 to lock the demonstration teaching mechanism 2. Compared with existing similar equipment, it can more conveniently unfold and store the demonstration teaching mechanism 2. The operation is simple, saves manpower and time, and has a better actual use effect.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
