Description

Technical Field

[0001] This utility model relates to the field of educational toys, and in particular to a rotating word-forming toy. Background Technology

[0002] As the core carrier of Chinese civilization, the learning and inheritance of Chinese characters is a key link in basic education. Character-building educational toys, with "disassembly and recombination" as their core logic, transform the complex, varied, and monotonous process of learning characters into an interactive physical form based on the structural rules of Chinese characters (such as radicals, single-component character combinations, and stroke composition). As an innovative educational tool that combines learning with entertainment, character-building toys play an irreplaceable role in early childhood education and Chinese character enlightenment. Through operations such as radical replacement and structural reorganization, they cultivate systematic thinking about the rules of Chinese character formation.

[0003] In existing word-building toys, the structure of Chinese characters is made into individual cards, and the cards are pieced together to form characters. However, the individual card type of word-building toys has the following obvious drawbacks: on the one hand, a large number of cards are needed to display the complete structure of Chinese characters, resulting in high storage space occupation and low efficiency in finding specific component cards; on the other hand, the cards are easy to lose or damage, which may cause key components to be missing, directly affecting the integrity of the Chinese character combination, thereby weakening children's interest and motivation to continue learning.

[0004] Therefore, there is an urgent need to design a word-forming toy to solve the above-mentioned technical problems. Utility Model Content

[0027] The beneficial effects of this utility model are as follows:

[0028] By rotating the character disks, children can form Chinese characters. Compared to individual card designs, the rotating character-forming toy uses multiple stacked character disks, significantly reducing the need for storage space. This makes the toy more compact and easier to store. The compact structure also makes it easy to carry, allowing children to learn and display their characters in different settings. Furthermore, the radicals and components are printed on the character disks, making them less likely to be lost or damaged, ensuring the integrity and continuity of character formation. The characters on the disks are arranged in a regular pattern, allowing for quick combinations of different Chinese characters. The rotating operation is simple and fun, increasing the interactivity between children and the toy and making the learning process more lively and engaging.

[0029] By layering transparent sections of multiple character discs, different characters on different discs can be combined according to arrangement rules to form characters with left-right, top-bottom, and compound structures, enriching the types and possibilities of character formation. Secondly, the transparent section design allows children to clearly see the characters in each layer when forming characters, enhancing visual intuitiveness and helping children better understand the hierarchical structure and construction rules of Chinese characters. Furthermore, the multi-layered and multi-structure character formation method increases the interactivity and exploratory nature of the toy, allowing children to experience more fun and a sense of accomplishment in the process of spelling words, thereby enhancing the enjoyment of learning Chinese characters.

[0030] By incorporating rotating assembly structures with two, three, four, or multiple layers, the toys are designed to be suitable for people of different ages or educational levels, thus enhancing the diversity of assembly toy products. Attached Figure Description

[0051] This section will describe in detail the specific embodiments of this application. Preferred embodiments of this application are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so as to intuitively and vividly understand each technical feature and overall technical solution of this application, but they should not be construed as limiting the scope of protection of this application.

When a feature is referred to as "set," "fixed," or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0053] In the description of this application, the term "several" means one or more, and "more than" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the number of indicated technical features, or the order of the indicated technical features.

[0054] Furthermore, unless otherwise defined, the technical and scientific terms used in this application have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this application is for the purpose of describing particular embodiments only and not for limiting the application. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.

[0055] Example 1: As Figure 1 As shown, a rotating character-assembly structure includes a core shaft 1 and at least two sets of character disks 8. Different characters are arranged on the outer ring wall of each character disk 8. The character disks 8 are rotatably assembled with the core shaft 1 and are coaxially arranged. Multiple sets of character disks 8 are arranged adjacently along the axis of the core shaft 1. Notably, characters with different radicals and components are printed on the outer ring wall of each character disk 8. By rotating the character disks 8, left-right structured Chinese characters can be assembled. Compared to independent card designs, the rotating character-assembly toy, through the stacking of multiple character disks 8, significantly reduces the need for storage space, making the toy more compact and easier to store. The compact structure also makes it easy to carry, facilitating children's learning and display in different situations. Furthermore, by fixing the radicals and components onto the character disks 8, they are less likely to be lost or damaged, ensuring the integrity and continuity of the Chinese character assembly. The characters on the character disks 8 are arranged according to a pattern, allowing children to quickly combine different Chinese characters. The rotating operation is simple and fun, increasing the interactivity between children and the toy, making the learning process more vivid and engaging.

[0056] Of course, different strokes, radicals, components, single characters and numerical symbols are printed on the character disk 8. By changing different character disks 8, the number and types of characters that can be spelled can be increased, and the difficulty and interest of playing with them can be adjusted.

[0057] To enhance the variety of characters, the character disk 8 includes a transparent part 801 and a rotating part 802. The transparent part 801 is used to print different characters. The transparent parts 801 of multiple character disks 8 are stacked sequentially to form a stacked area. The rotating part 802 is used to rotate the transparent part 801. The rotating parts 802 of multiple character disks 8 are arranged adjacent to each other along the axis of the spindle 1. The character disks 8 are equipped with transparent sections 801, and multiple sets of transparent sections 801 on different character disks 8 are stacked sequentially. This allows different characters on different character disks 8 to be combined according to arrangement rules to form fonts with left-right, top-bottom, and compound structures. Through the stacking design of the transparent sections 801, characters on different character disks 8 can be superimposed and combined with each other, not limited to left-right structures, but also easily achieving diverse font combinations such as top-bottom and compound structures, greatly enriching the types and possibilities of character formation. Secondly, the design of the transparent sections 801 allows children to clearly see the characters in each layer when forming characters, enhancing visual intuitiveness and helping children better understand the hierarchical structure and construction rules of Chinese characters. Furthermore, the multi-layered and multi-structure character formation method increases the interactivity and exploratory nature of the toy, allowing children to experience more fun and a sense of accomplishment in the process of spelling words, thereby enhancing the fun of learning Chinese characters.

[0058] The transparent material used in the transparent part 801 is a material in the prior art, such as polypropylene, polyethylene, transparent TPE and other transparent plastics commonly used in children's toys.

[0059] Example 2: Figures 1-2 As shown, a two-layer rotating character-building toy includes a rotating character-building structure as described in Embodiment 1. The character disk 8 includes a first rotating cylinder 201 and a second rotating cylinder 202 that are sequentially rotated and assembled on a spindle 1. The transparent parts 801 of the first rotating cylinder 201 and the transparent parts 801 of the second rotating cylinder 202 are arranged vertically to form a first layer. The rotating parts 802 of the first rotating cylinder 201 and the rotating parts 802 of the second rotating cylinder 202 are located on opposite sides of the first layer. The rotating character-building toy in this embodiment has a two-layer character disk 8 structure. By adopting a two-layer structure, simple Chinese characters, single characters composed of strokes, or Chinese characters that are not complex left-right or top-bottom structures can be combined. The two-layer character disk 8 structure design simplifies the character-building process and is especially suitable for beginners. Through the vertically overlapping transparent parts 801, children can clearly see the combination effect of the two layers of characters, making it easier to combine simple Chinese characters or single characters composed of strokes. This design reduces the learning difficulty, allows beginners to get started quickly, and enhances their learning confidence.

[0060] Regarding the specific structure of the first layer formed by the first rotating cylinder 201 and the second rotating cylinder 202, the transparent part 801 of the second rotating cylinder 202 is provided with a first support groove 2021. The transparent part 801 of the first rotating cylinder 201 is located on the first support groove 2021. It is worth mentioning that since the transparent part 801 of the second rotating cylinder is located at the bottom layer, the transparent part 801 of the second rotating cylinder does not need to be transparent in terms of material. The design of the first support groove 2021 allows the transparent part 801 of the first rotating cylinder 201 to be stably placed on the second rotating cylinder 202, forming an integrated structure, which effectively prevents shaking or misalignment during rotation and enhances the overall stability and durability of the toy.

[0061] To ensure the stability of the character disk 8 after rotation and character assembly, this embodiment also includes an elastic element. The elastic element is assembled with the spindle 1, and the elastic part of the elastic element is exposed on the outer ring wall of the spindle 1. The inner ring of the character disk 8 has a first groove 2022 that elastically engages with the elastic element. It is worth mentioning that the elastic element is an elastic pin. Through the assembly of the elastic element with the spindle 1 and the elastic engagement design between the inner ring of the character disk 8 and the elastic element, it is ensured that the character disk 8 can be firmly fixed in a specific position after rotation and character assembly, avoiding errors or unclear character combinations due to loosening or displacement. Secondly, the setting of the elastic element effectively prevents the character disk 8 from accidentally sliding or shifting during rotation, thereby ensuring the accuracy and consistency of character combinations, which is beneficial for users to correctly learn and recognize the structure of Chinese characters.

[0062] To ensure that the elastic element can automatically disengage when the character disk 8 is rotated after it is engaged in the first groove 2022, the contact part between the elastic element and the first groove 2022 is arc-shaped. Similarly, the inner wall of the first groove 2022 is arc-shaped, thereby realizing the function of disengaging-engaging-disengaging as the character disk 8 rotates. Of course, the principle of this structure is the same as the handle storage of a folding umbrella, which is a structure well known to those skilled in the art, and will not be described in detail here.

[0063] In terms of the specific structural design of the first groove 2022 on the character disk 8, multiple sets of the first groove 2022 are provided, and the first groove 2022 corresponds to the characters on the character disk 8. It is worth mentioning that the first groove 2022 located on the inner circle of the character disk 8 and the corresponding characters located on the outer circle of the character disk 8 are located on the same diameter of the character disk 8. This ensures that when the elastic element is engaged in the first groove 2022, it is in the position of the corresponding character. Since the first groove 2022 corresponds one-to-one with the characters on the character disk 8 and is located on the same diameter, this design ensures that when the elastic element is engaged in the first groove 2022, the corresponding character position can be accurately located. In this way, when rotating and assembling characters, the required characters can be found and fixed more quickly and accurately, improving the efficiency and accuracy of character assembly.

[0064] Example 3: AsFigure 1 , Figure 3 , Figure 4 As shown, a three-layer rotating character-forming toy includes a rotating character-forming structure as described in Embodiment 1. The character disk 8 includes a third rotating cylinder 301, a fourth rotating cylinder 302, and a fifth rotating cylinder 303 sequentially rotatably mounted on a spindle 1. The transparent portions 801 of the third rotating cylinder 301, the fourth rotating cylinder 302, and the fifth rotating cylinder 303 are arranged in an overlapping manner to form a second layer. The rotating portions 802 of the third rotating cylinder 301 and the fifth rotating cylinder 303 are located on opposite axial sides of the second layer. The rotating portion 802 of the fourth rotating cylinder 302 is located on the third rotating cylinder. Specifically, the transparent parts 801 of the fourth, third, and fifth rotating cylinders 302, and the transparent parts 801 of the fourth, third, and fifth rotating cylinders 303 are arranged in a staggered, overlapping manner. The rotating character-forming toy in this embodiment features a three-layer character disk 8 structure. This three-layer structure allows for the combination of left-middle-right, top-middle-bottom structures, and relatively complex single Chinese characters. The overlapping arrangement of the three character disks 8 through the third, fourth, and fifth rotating cylinders 303 significantly increases the possibilities for character combination. It not only allows for easy combination of left-middle-right and top-middle-bottom structures but also handles more complex single Chinese characters, providing a richer learning experience and helping learners to more comprehensively understand and master the structure and writing rules of Chinese characters.

[0065] Regarding the specific structure of the second stacked section formed by the third rotating cylinder 301, the fourth rotating cylinder 302, and the fifth rotating cylinder 303, the fourth rotating cylinder 302 is T-shaped, and the transparent portion 801 and the rotating portion 802 of the fourth rotating cylinder 302 are located at both axial ends of the fourth rotating cylinder 302. The third rotating cylinder 301 has a first T-shaped groove 3011 recessed radially from the outer ring wall inwards. The fourth rotating cylinder 302 is rotatably fitted into the first T-shaped groove 3011, and the rotating portion 802 of the fourth rotating cylinder 302 is positioned close to the rotating portion 802 of the third rotating cylinder 301. The transparent portion 801 of the third rotating cylinder 301 extends axially along the third rotating cylinder 301 and is located below the transparent portion 801 of the fourth rotating cylinder 302. The transparent part 801 of the fifth rotating cylinder 303 is recessed from the outside to the inside and is provided with a second support groove 3031. The transparent part 801 of the third rotating cylinder 301 is located above the bottom wall of the second support groove 3031 and the rotating part 802 of the fifth rotating cylinder 303 is located away from the rotating part 802 of the fourth rotating cylinder 302. The T-shaped design of the fourth rotating cylinder 302 and the layout of its transparent part 801 and rotating part 802 at both ends of the axial direction ensure the stability and balance of the rotating cylinder during rotation. The assembly method of the first T-shaped groove 3011 of the third rotating cylinder 301 and the fourth rotating cylinder 302 not only limits the position of the fourth rotating cylinder 302, but also allows the rotating parts 802 of the three rotating cylinders to be arranged in the same axial direction, thereby achieving more precise character alignment and combination.

[0066] To ensure the stability of the third rotating cylinder 301 after character formation, this embodiment also includes a first elastic element 304. The first elastic element 304 is assembled with the spindle 1, and the elastic part of the first elastic element 304 is exposed on the outer ring wall of the spindle 1. The inner ring of the third rotating cylinder 301 has a second groove 3012 that elastically engages with the first elastic element 304. It is worth mentioning that the first elastic element 304 is an elastic pin. Through the assembly of the first elastic element 304 with the spindle 1 and the elastic engagement design between the inner ring of the third rotating cylinder 301 and the elastic element, it is ensured that the third rotating cylinder 301 can be stably fixed in a specific position after character formation, avoiding errors or unclear character combinations due to loosening or displacement. Furthermore, the setting of the first elastic element 304 effectively prevents the character disk 8 from accidentally sliding or shifting during rotation, thereby ensuring the accuracy and consistency of character combinations, which is beneficial for users to correctly learn and recognize the structure of Chinese characters.

[0067] To ensure that the first elastic element 304 can automatically disengage when the third rotating cylinder 301 rotates after it is engaged in the second groove 3012, the contact part between the first elastic element 304 and the second groove 3012 is arc-shaped. Similarly, the inner wall of the second groove 3012 is arc-shaped, thereby realizing the function of disengaging-engaging-disengaging as the third rotating cylinder 301 rotates. Of course, the principle of this structure is the same as that of the handle storage of a folding umbrella, which is a structure well known to those skilled in the art and will not be described in detail here.

[0068] In terms of the specific structural design of the second groove 3012 of the third rotating cylinder 301, multiple sets of the second groove 3012 are provided, and the second groove 3012 corresponds to the character settings on the third rotating cylinder 301. It is worth mentioning that the second groove 3012 located on the third rotating cylinder 301 and the corresponding character located on the outer ring of the third rotating cylinder 301 are located on the same diameter of the third rotating cylinder 301. This ensures that when the elastic element is engaged in the second groove 3012, it is at the position of the corresponding character. Since the second groove 3012 corresponds one-to-one with the characters on the third rotating cylinder 301 and is located on the same diameter, this design ensures that when the first elastic element 304 is engaged in the second groove 3012, it can accurately position the corresponding character. In this way, when rotating to form characters, the required characters can be found and fixed more quickly and accurately, improving the efficiency and accuracy of character formation.

[0069] To ensure the stability of the fourth rotating cylinder 302 after it rotates to form characters, this embodiment also includes a second elastic member 305. The second elastic member 305 is assembled with the third rotating cylinder 301, and the elastic part of the second elastic member 305 is exposed on the side wall of the first T-shaped groove 3011. The side wall of the fourth rotating cylinder 302 has a third groove 3021 that elastically engages with the second elastic member 305. It is worth noting that the second elastic member 305 is an elastic pin or a U-shaped spring with protrusions. Through the interaction between the second elastic member 305 and the third rotating cylinder 301... The assembly, and the elastic snap-fit ​​design between the inner ring of the third rotating cylinder 301 and the first elastic element 304, ensure that the fourth rotating cylinder 302 can be firmly fixed in a specific position after rotating to assemble the characters, avoiding errors or unclear character combinations due to loosening or displacement. Of course, since the fourth rotating cylinder 302 is assembled on the third rotating cylinder 301 and both are elastically snap-fitted, in actual operation, in order to avoid rotating the third rotating cylinder 301 and causing the fourth rotating cylinder 302 to rotate, one of the rotating cylinders can be pressed with a finger.

[0070] To ensure that the second elastic element 305 can automatically disengage after being engaged in the second groove 3012, the contact portion between the second elastic element 305 and the third groove 3021 is arc-shaped. Similarly, the inner wall of the third groove 3021 is arc-shaped.

[0071] The third groove 3021 is provided in multiple sets, and the third groove 3021 corresponds to the character setting on the third rotating cylinder 301.

[0072] To ensure the stability of the third rotating cylinder 301 after character assembly by rotation, this embodiment further includes a third elastic member 306. The third elastic member 306 is assembled with the fifth rotating cylinder 303, and the elastic part of the third elastic member 306 is exposed on the side wall of the fifth rotating cylinder 303 facing the fourth rotating cylinder 302. The third rotating cylinder 301 is provided with a fourth groove 3013 for elastic snap connection with the third elastic member 306. It is worth noting that the second elastic member 305 is an elastic thimble or a U-shaped elastic sheet with convex points, ensuring that the fifth rotating cylinder 303 can be firmly fixed at a specific position after character assembly by rotation. Of course, during actual operation, to avoid the fifth rotating cylinder 303 being rotated when the third rotating cylinder 301 or the fourth rotating cylinder 302 is rotated, the method of pressing the rotating cylinder with fingers can be used to avoid this situation.

[0073] To ensure that the third elastic member 306 can automatically release the snap connection after being snapped into the fourth groove 3013, the contact part of the third elastic member 306 with the fourth groove 3013 is arranged in an arc shape. Similarly, the inner wall of the fourth groove 3013 is arranged in an arc shape.

[0074] Among them, multiple groups of the fourth grooves 3013 are provided, and the fourth grooves 3013 are arranged corresponding to the characters on the fifth rotating cylinder 303.

[0075] Embodiment 4: As Figure 1 、 Figures 5 to 7 shown, a four-layer rotating character assembly toy includes a rotating character assembly structure of Embodiment 1. The character disk 8 includes a sixth rotating cylinder 401, a seventh rotating cylinder 402, an eighth rotating cylinder 403, and a ninth rotating cylinder 404 that are sequentially assembled on the core shaft 1. The transparent parts 801 of the sixth rotating cylinder 401, the seventh rotating cylinder 402, the eighth rotating cylinder 403, and the ninth rotating cylinder 404 are arranged in an overlapping manner up and down to form a third stacked layer. The rotating parts 802 of the sixth rotating cylinder 401 and the seventh rotating cylinder 402 are located on one side of the third stacked layer and are arranged in sequence along the axial direction of the core shaft 1. The rotating parts 802 of the eighth rotating cylinder 403 and the ninth rotating cylinder 404 are located on the other side of the third stacked layer and are arranged in sequence along the axial direction of the core shaft 1. The rotating character assembly toy in this embodiment is provided with a four-layer character disk 8 structure. By adopting a four-layer stacked structure, it not only has the functions of two-layer and three-layer structures, but also combines single characters of upper-middle-lower or left-middle-right structures with upper-lower-left-right mixed structures, such as "tang", "ting", "shu", "shuang", "shuang", etc.

[0076] Regarding the specific structure of the third layer formed by the sixth rotating cylinder 401, the seventh rotating cylinder 402, the eighth rotating cylinder 403, and the ninth rotating cylinder 404, the seventh rotating cylinder 402 is T-shaped, and the transparent part 801 and the rotating part 802 of the seventh rotating cylinder 402 are located at both axial ends of the seventh rotating cylinder 402. The sixth rotating cylinder 401 has a second T-shaped groove 4011 recessed radially from the outer ring wall inward. The seventh rotating cylinder 402 is rotatably assembled with the second T-shaped groove. In groove 4011, the rotating part 802 of the seventh rotating cylinder 402 is disposed close to the rotating part 802 of the sixth rotating cylinder 401. The transparent part 801 of the sixth rotating cylinder 401 extends along the axial direction of the sixth rotating cylinder 401 and is located below the transparent part 801 of the seventh rotating cylinder 402. The transparent part 801 of the eighth rotating cylinder 403 is recessed from the outside to the inside and is provided with a third support groove 4031. The transparent part 801 of the sixth rotating cylinder 401 is located on the bottom wall of the third support groove 4031. The ninth rotating cylinder 404 has a radially recessed mounting groove 4041 extending inward from its outer ring wall. The eighth rotating cylinder 403 is rotatably mounted in the mounting groove 4041. A limiting groove 4032 is formed in the transparent portion 801 of the eighth rotating cylinder 403, recessed inward from the side wall of the eighth rotating cylinder 403 towards the sixth rotating cylinder 401. The transparent portion 801 of the ninth rotating cylinder 404 is located in the limiting groove 4032. This is achieved through the T-shaped design of the seventh rotating cylinder 402 and... The layout of its transparent part 801 and rotating part 802 located at both ends of the axis ensures the stability and balance of the rotating cylinder during rotation. The rotation of the second T-shaped groove 4011 of the sixth rotating cylinder 401 and the seventh rotating cylinder 402, and the assembly method of the eighth rotating cylinder 403 and the ninth rotating cylinder 404, not only limit the position of the seventh rotating cylinder 402 and the eighth rotating cylinder 403, but also enable the rotating parts 802 of four sets of rotating cylinders to be arranged in the same axis, thereby achieving more precise character alignment and combination.

[0077] To ensure the stability of the sixth rotating cylinder 401 after character formation, this embodiment also includes two sets of fourth elastic elements 405. The two sets of fourth elastic elements 405 are assembled with the spindle 1 and spaced apart. The elastic part of the fourth elastic element 405 is exposed on the outer ring wall of the spindle 1. The inner ring of the sixth rotating cylinder 401 and the inner ring of the eighth rotating cylinder 403 are both provided with fifth grooves 4033 that elastically engage with the fourth elastic elements 405. It is worth mentioning that the fourth elastic element 405 is an elastic pin, which avoids incorrect or unclear character combination due to loosening or displacement. Secondly, the setting of the fourth elastic element 405 effectively prevents the character disk 8 from accidentally sliding or shifting during rotation, thereby ensuring the accuracy and consistency of character combination, which is beneficial for users to correctly learn and recognize the structure of Chinese characters.

[0078] To ensure that the fourth elastic element 405 can automatically disengage after being engaged in the fifth groove 4033, the contact area between the fourth elastic element 405 and the fifth groove 4033 is arc-shaped. Similarly, the inner wall of the fifth groove 4033 is arc-shaped.

[0079] In terms of the specific design of the fifth groove 4033 in the sixth rotating cylinder 401, the sixth rotating cylinder 401 is provided with multiple sets of fifth grooves 4033, and the fifth grooves 4033 correspond to the character settings on the sixth rotating cylinder 401. The eighth rotating cylinder 403 is set in the same way.

[0080] To ensure the stability of the seventh rotating cylinder 402 after it rotates to form characters, this embodiment also includes a fifth elastic element 406. The fifth elastic element 406 is assembled with the sixth rotating cylinder 401, and the elastic part of the fifth elastic element 406 is exposed on the side wall of the second T-shaped groove 4011. The side wall of the seventh rotating cylinder 402 has a sixth groove 4021 that elastically engages with the fifth elastic element 406. It is worth noting that the fifth elastic element 406 is an elastic pin or a U-shaped spring with protrusions. Through the interaction between the fifth elastic element 406 and the sixth rotating cylinder 401... The assembly, and the elastic snap-fit ​​design between the inner ring of the sixth rotating cylinder 401 and the fifth elastic element 406, ensure that the seventh rotating cylinder 402 can be firmly fixed in a specific position after rotating to assemble the characters, avoiding errors or unclear character combinations due to loosening or displacement. Of course, since the seventh rotating cylinder 402 is assembled on the sixth rotating cylinder 401 and both are elastically snap-fitted, in actual operation, in order to avoid rotating the sixth rotating cylinder 401 and causing the seventh rotating cylinder 402 to rotate, one of the rotating cylinders can be pressed with a finger.

[0081] To ensure that the fifth elastic element 406 can automatically disengage after being engaged in the sixth groove 4021, the contact area between the fifth elastic element 406 and the sixth groove 4021 is arc-shaped. Similarly, the inner wall of the sixth groove 4021 is arc-shaped.

[0082] The sixth groove 4021 is provided in multiple sets, and the sixth groove 4021 corresponds to the character settings on the sixth rotating cylinder 401.

[0083] To ensure the stability of the sixth rotating cylinder 401 after rotating to form characters, this embodiment also includes a sixth elastic element 407. The sixth elastic element 407 is assembled with the eighth rotating cylinder 403, and the elastic part of the sixth elastic element 407 is exposed on the side wall of the eighth rotating cylinder 403 facing the mounting groove 4041. The side wall of the mounting groove 4041 is provided with a seventh groove 4042 for elastically engaging with the sixth elastic element 407. It is worth mentioning that the fifth elastic element 406 is an elastic pin or a U-shaped spring with protrusions, which ensures that the eighth rotating cylinder 403 can be stably fixed in a specific position after rotating to form characters. Of course, in actual operation, in order to avoid the eighth rotating cylinder 403 being rotated when the ninth rotating cylinder 404 is rotated, the ninth rotating cylinder 404 can be pressed with a finger.

[0084] To ensure that the sixth elastic element 407 can automatically disengage after being engaged in the seventh groove 4042, the contact area between the sixth elastic element 407 and the seventh groove 4042 is arc-shaped. Similarly, the inner wall of the seventh groove 4042 is arc-shaped.

[0085] The seventh groove 4042 is provided in multiple sets, and the seventh groove 4042 corresponds to the character setting on the eighth rotating cylinder 403.

[0086] Example 5: Figure 1 , Figures 8 to 11 As shown, a multi-layer rotating character-forming toy includes a rotating character-forming structure of Embodiment 1, a two-layer rotating character-forming toy of Embodiment 2, a three-layer rotating character-forming toy of Embodiment 3, or a four-layer rotating character-forming toy of Embodiment 4. This embodiment also includes two sets of end clips 5, which are respectively assembled at both ends of the axis of the spindle 1. The radial length of the end clips 5 is greater than the inner diameter of the inner ring of the character disk 8. It should be noted that the radial length of the end clips 5 refers to the distance of the end clips 5 along the diameter direction of the spindle 1. By assembling end clips 5 at both ends of the spindle 1, and ensuring that the radial length of the end clips 5 is greater than the inner diameter of the inner ring of the character disk 8, the axial movement of the character disk 8 on the spindle 1 can be effectively restricted. This design ensures that the character disk 8 will not loosen along the axial direction of the spindle 1 after assembly, greatly improving the assembly stability of the character disk 8.

[0087] Regarding the assembly of the end clamp 5 and the spindle 1, the end clamp 5 is disc-shaped, and the diameter of the end clamp 5 is equal to the outer diameter of the character disk 8. The spindle 1 has a snap-fit ​​hole 101 along its axial direction. The end clamp 5 has a snap-fit ​​protrusion 501 that is protruded and used to snap-fit ​​with the snap-fit ​​hole 101. The axis of the snap-fit ​​protrusion 501 is coaxial with the axis of the end clamp 5, so that the end clamp 5 and the spindle 1 snap-fit ​​together.

[0088] To help the operator concentrate on character assembly and avoid distractions from other characters surrounding the character disk 8, the end clip 5 is equipped with a baffle 502 located outside the character disk 8. The baffle 502 has a display window 5021, which displays a single character in the circumferential direction of the character disk 8. The baffle 502 extends from the axial sidewall of the clip along the axial direction of the character disk 8. The size of the display window 5021 is equal to the size of the character after assembly on the character disk 8. The design of the baffle 502 effectively blocks other characters on the character disk 8, allowing the operator to concentrate more on the single character that needs to be processed when assembling characters. By displaying only the current character through the display window 5021, visual interference is reduced, which helps to improve the accuracy and efficiency of character assembly.

[0089] To enhance the diversity of toys, this embodiment also includes multiple sets of pinyin discs 6. The outer ring of each pinyin disc 6 is decorated with different pinyin letters. The pinyin discs 6 are rotatably assembled with the spindle 1 and are coaxially positioned. Multiple sets of pinyin discs 6 are arranged adjacent to each other along the axis of the spindle 1, located between the character disc 8 and the end clip 5. The outer ring of each set of pinyin discs 6 is printed with initials or finals. By setting multiple sets of pinyin discs 6, each with different pinyin letters, children can freely combine these pinyin discs 6 during play, thereby learning and recognizing more pinyin letters. The combination of sounds not only increases the interactivity of the toy but also enhances its educational function, helping children learn pinyin and improve their language skills through play. Secondly, the multiple sets of pinyin discs 6 provide more variations and combination possibilities, allowing children to create various pinyin combinations by rotating different discs 6 according to their interests and needs, greatly improving the toy's playability. Furthermore, the pinyin discs 6 are located between the character disc 8 and the end clip 5, ensuring their visibility and operability without interfering with the normal use of the character disc 8. In this embodiment, three sets of pinyin discs 6 are provided.

[0090] To ensure the stability of the Pinyin disk 6 after it rotates to form characters, the Pinyin disk 6 and the spindle 1 are also assembled using elastic components to hold the Pinyin disk 6 in place. The structure and principle are the same as those of the character disk 8 and the spindle 1, so we will not go into too much detail here.

[0091] Furthermore, to enable tone marking after rotation of the pinyin, this embodiment also includes a tone flip plate 601 and a ring-shaped component 602. The ring-shaped component 602 is connected to the baffle 502. One end of the tone flip plate 601 is rotatably assembled with the ring-shaped component 602. One end of the tone flip plate 601 has a through hole for rotatably assembling with the ring-shaped component 602. By flipping the tone flip plate 601 to rotate along the ring-shaped component 602, different tones can be switched. Through the design of the tone flip plate 601, children can easily switch and mark different tones after combining pinyin. This not only makes the toy's pinyin function more complete but also greatly enhances its educational function, helping children learn and master the tone knowledge of Chinese pinyin more comprehensively and improve pronunciation accuracy.

[0092] In this embodiment, each set of pinyin disks 6 is provided with a set of ring parts 602 and five sets of tone flips 601 to mark the tone. The five sets of tone flips 601 correspond to four tones and open pages respectively to achieve accurate tone marking.

[0093] To enhance the diversity of character combinations, this embodiment also includes several sets of character discs 7. The outer ring wall of each character disc 7 is decorated with different Chinese characters. The character discs 7 are rotatably assembled with the spindle 1 and are coaxially arranged. The character discs 7 are located between the pinyin disc 6 and the end clip 5. There are multiple sets of character discs 7, and the multiple sets of pinyin discs 6 are arranged adjacent to each other along the axis of the spindle 1. By rotating the character discs 7, different Chinese characters can be switched to achieve the effect of word combination. By adding several sets of character discs 7, each with different Chinese characters engraved on it, and rotating the character discs 7 to switch and combine various Chinese characters, the effect of word combination is achieved, greatly expanding the diversity of character combinations, enriching the content of language learning, and enabling children to learn and master more Chinese characters and vocabulary while playing. Furthermore, the coaxial arrangement and sequential arrangement of the character discs 8, pinyin discs 6, character discs 7, and end clips 5 cleverly utilize the spatial layout and achieve a high degree of integration of multiple functions.

[0094] To ensure the stability of the word-forming disk after it rotates and forms characters, the assembly structure of the word-forming disk and the spindle 1 also uses elastic components to lock the word-forming disk in place. The structure and principle are the same as those of the character disk 8 and the spindle 1, so we will not go into too much detail here.

[0095] To guide learning, expand the range of characters that can be spelled, and increase different points of interest, the character disk 8 also includes a character replacement disk, and the text disk 8 also includes a text replacement disk. The character replacement disk is rotatably assembled with the spindle 1 and is used to replace the character disk 8. The pinyin replacement disk is rotatably assembled with the spindle 1 and is used to replace the pinyin disk 6. The text replacement disk is rotatably assembled with the spindle 1 and is used to replace the text disk 8. In actual play, you can freely replace the disks printed with different characters, which is of great value in mastering knowledge points. It should be noted that the strokes, radicals, components, and single-component characters printed on the character replacement disk are not exactly the same as those on the character disk 8, and the characters printed on the text replacement disk are not exactly the same as those on the text disk 7, so as to achieve the purpose of replacement.

[0096] To confirm the correctness of the assembled Chinese characters, rotate the assembled characters and... Figure 11 By comparing the provided character lookup table with the actual character toy and using it in conjunction with identification applications, a unique integrated hardware and software educational toy is formed. It provides calibration and expansion for people of different ages or educational levels after playing with and assembling characters. It is worth mentioning that the character lookup table is only for illustrating the principle. When actually using it, multiple pages of character lookup tables are needed to cover the various permutations and combinations of the character toy.

[0097] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
