Example 1

Referring to fig. 1, fig. 1 is a schematic structural diagram of a teaching aid 100 provided in this embodiment, which includes a fixing rod 112 and a plurality of wave-shaped rods 114, wherein any wave-shaped rod 114 is in transmission connection with the fixing rod 112, and a length extending direction of any wave-shaped rod 114 intersects with a length extending direction of the fixing rod 112, and the plurality of wave-shaped rods 114 can cooperate to form a wave shape. Moreover, the teaching aid 100 can convert the waveform curve which is relatively abstract and difficult to understand into a real object, and the difficulty in learning and understanding is reduced.

Specifically, in the present embodiment, the teaching aid 100 includes a fixing rod 112 and a plurality of wave-shaped rods 114, and any wave-shaped rod 114 is perpendicular to the fixing rod 112, as shown in fig. 2, fig. 2 is a schematic view of the fixing rod 112 and the wave-shaped rod 114 provided in the present embodiment in cooperation. Further, a plurality of gears 116 are provided on the fixed lever 112, and the number of the gears 116 corresponds to the number of the wave levers 114. Thus, the fixed rod 112 serves as a fixed support point for the wave-shaped rod 114 and also serves as a reference base line for the wave-shaped rod, so that the visual perception of the wave-shaped rod is stronger, and the memory point is strengthened. In this embodiment, a gear 116 is engaged with one side of a wave bar 114, so as to achieve the effect of adjusting the length of the wave bar 114 (the length of the wave bar 114 in the upward direction of the fixing bar 112 with the fixing bar 112 as a reference base line), thereby facilitating the user to quickly adjust the wave shape object and having strong practicability. When a user needs to adjust the waveform, pressure can be applied to one end of the waveform rod 114, the length of the waveform rod 114 is changed, the plurality of waveform rods 114 are matched to form a sine wave, a square wave, a triangular wave or a sawtooth wave real object, a learner can observe the waveform from a plurality of angles, understanding is difficult, abstract waveforms are converted into three-dimensional real objects, understanding difficulty is reduced, and learning effect is improved. In addition, the height (taking the fixed rod 112 as a reference base line) of the wave-shaped rod 114 controlled by the gear 116 is more accurate and stable in a meshing mode, and after the height is adjusted, the wave-shaped rod 114 slides down under the action of self gravity, so that the height is not changed unexpectedly, the adjustment precision is improved, and the use is more convenient.

In other embodiments, the length extending direction of the wave bars 114 may not be perpendicular to the length extending direction of the fixing bars 112, but may be in an intersecting state, so that a plurality of wave bars 114 may be matched to form different types of wave forms, and the learning interest and the ability of students to play a third role may be enhanced, which is beneficial for the lecturer to explain the relevant content of the wave forms. It should be noted that, in the embodiment, the plurality of wave bars 114 are disposed in parallel on the fixing rod 112, so that the waveform of the lecturer and/or the student can be adjusted conveniently, the phenomenon of visual confusion caused by the crossing of the wave bars 114 is avoided, and the using effect is stronger. However, on the basis of mastering the waveform, the crossed waveform rods 114 can be arranged, so that the operation difficulty is improved, and the understanding and mastering of the waveform change by students are enhanced.

In this embodiment, a sliding groove 120 is disposed on a side wall of the wave-shaped rod 114, and a limiting block 122 adapted to the sliding groove 120 is disposed at a position corresponding to the fixing rod 112. In detail, when pressure is applied to one end of the wave rod 114, the sliding groove 120 on the wave rod 114 cooperates with the stopper 122, the wave rod 114 slides up and down along the length direction of the sliding groove 120, and at this time, the cooperation of the stopper 122 and the sliding groove 120 can adjust the wave rod 114 at a preset position, so that the stability is stronger. In addition, when the gear 116 is damaged or is obstructed in use, the matching of the sliding groove 120 and the limiting block 122 can also enable the height of the wave-shaped rod 114 to be adjusted easily and conveniently, and the practicability is high. It should be noted that the sliding groove 120 and the stopper 122 cooperate to reduce friction and wear of the wave lever 114, which results in a longer service life. In addition, the sliding slot 120 can also limit the maximum adjustment length of the wave-shaped rod 114, for example, when the upper end (the top end shown in fig. 2) of the wave-shaped rod 114 needs to be pressed down to the position of the fixing rod 112, the wave-shaped rod 114 is easy to slide out of the fixing rod 112, which is not only easy to lose, but also inconvenient for the user, and has poor effect. However, in the embodiment, the sliding groove 120 is a groove on the side wall of the wave-shaped rod 114 and has a port, as shown in fig. 2, therefore, the two ends of the sliding groove 120 limit the maximum adjusting length of the wave-shaped rod 114, and the wave-shaped rod 114 is not easy to fall off, so that the practicability and convenience are higher.

In other embodiments, a plurality of resilient bumps may be provided on the side walls of the chute 120. When pressure is applied, the stopper 122 squeezes the resilient bumps and slides over the resilient bumps, facilitating the user to adjust the length of the wave lever 114. When pressure is not applied, the elastic convex blocks play a role in limiting, so that the waveform rod 114 can keep an adjusting state, and the related content of the waveform can be conveniently explained.

In this embodiment, the arrangement manner of the gear 116 is as shown in fig. 3, and fig. 3 is a side view of the fixing rod 112 provided in this embodiment. Specifically, one end of the gear 116 penetrates through the side wall of the fixing rod 112 to be meshed with the wave-shaped rod 114, and the other end of the gear 116 is exposed outside the fixing rod 112, so that on one hand, the gear 116 is convenient to replace, and the practicability is high, on the other hand, the gear 116 exposed outside can be matched with the fixing auxiliary rod 124 in the embodiment, so that multiple abstract sine waves or other various waveforms are converted into real objects, understanding is convenient, and learning efficiency is high. In this embodiment, the fixing rod 112 is a hollow structure. The fixing rod 112 with a hollow structure can not only reduce the weight of the teaching aid 100, but also facilitate the installation of the gear 116, and has strong practicability.

Moreover, any clamping groove 128 is arranged between two adjacent wave-shaped auxiliary rods 126, and the distance between the clamping groove 128 and the wave-shaped auxiliary rods 126 can enable the gear 116 to be in contact with and meshed with the wave-shaped auxiliary rods 126, so that the control effect is achieved.

In this embodiment, the length extending direction of the wave-shaped sub-rod 126 is the same as the length extending direction of the wave-shaped rod 114, and the length extending direction of the fixed sub-rod 124 is the same as the length extending direction of the fixed rod 112. When the setting directions of the waveform rod 114 and the waveform auxiliary rod 126 are the same, the two waveform visual effects formed by the waveform rod 114 and the waveform auxiliary rod 126 are better, so that waveform confusion is avoided, the situation that multiple waveforms are more abstract occurs, and the learning effect is better.

In addition, the shape of the waveform can be changed during explanation, so that the change of the waveform is convenient to explain, and the learning effect is good. It should be noted that the wave-shaped auxiliary rod 126 can be provided with a toothed edge 118 on one side, and the wave-shaped auxiliary rod can cooperate with the wave-shaped rod 114 to convert abstract and unintelligible wave shapes into physical objects, so that difficulties can be easily mastered.
