Abstract
Description
Technical Field
[0001] This utility model relates to the field of toys, and more particularly to an assembly toy. Background Technology
[0002] Building blocks, composed of various universal components, can stimulate children's creativity and allow them to assemble various shapes. However, existing products generally have significant defects in their connection structures: some products use simple interference fits, requiring excessive torque for disassembly, which is quite strenuous for children whose strength is not yet fully developed; other products, in pursuit of connection stability, have designed complex locking mechanisms, forcing users to perform specific unlocking steps before disassembly. This not only increases the difficulty of operation but also greatly reduces the core fun and ease of play of the toy. Utility Model Content
[0003] This utility model aims to solve the technical problems in the prior art mentioned above, and proposes a connecting structure for an assembly toy, including a first connector and a second connector, wherein: the first connector has a protruding structure, and the outer surface of the protruding structure forms a first wavy step; the second connector has a recessed structure, and the inner surface of the recessed structure forms a second wavy step that cooperates with the first wavy step; wherein, the protruding structure and the recessed structure cooperate and lock each other to realize the detachable connection of the first connector and the second connector, and when the first connector rotates relative to the second connector, the first wavy step and the second wavy step generate an interaction force, causing the locking of the protruding structure and the recessed structure to be released, thereby separating the first connector and the second connector.
[0004] Furthermore, the first and second wavy steps have crests and troughs, and a slope between the crests and troughs, the slope angle being 30° to 60°.
[0005] Furthermore, a smooth surface transition is used between the peaks and troughs.
[0006] Furthermore, the first wave-shaped step is evenly distributed circumferentially along the outer surface of the protruding structure to form a continuous wave structure; the second wave-shaped step is evenly distributed circumferentially along the inner surface of the recessed structure to form a continuous wave structure.
[0007] Furthermore, the first wavy step and the second wavy step have the same thickness in the horizontal direction, so that when the first wavy step and the second wavy step are fitted together, their contact surfaces are completely aligned.
[0008] Furthermore, the top of the protruding structure in the axial direction is provided with a notch, and at least two lobed fins are provided inwardly extending from the notch; the bottom of the recessed structure in the axial direction is provided with a protrusion that cooperates with the notch, and a boss is provided on the outer side of the protrusion. The boss and the fins can engage with each other to fix the first connector and the second connector together.
[0009] Furthermore, at least two of the fins move closer together at the ends away from the notch. When the protrusion is inserted into the notch, the boss causes the fins to deform and move away from each other. When the boss passes over the fin, the fin returns to its original shape, and the edge of the fin engages with the boss.
[0010] Furthermore, the head of the protrusion is provided with a guide slope.
[0011] Furthermore, the head of the protrusion is provided with a groove. When subjected to compressive force, the groove becomes smaller, and the protrusion deforms toward the axis.
[0012] Furthermore, both the first connector and the second connector are made of plastic.
[0013] The connection structure of this invention, through the interlocking wave-shaped steps on the protruding and recessed structures, effectively overcomes the shortcomings of traditional interference-fit connections, which are laborious to assemble and disassemble, and complex locking mechanisms that are cumbersome to operate. A stable connection can be achieved through direct plug-in, ensuring the reliability of the assembled model; separation is achieved through rotation, guided by the sloping surface of the wave-shaped steps, allowing children to easily disassemble the toy, significantly reducing the difficulty of operation and the strength required. This structure is intuitive and simple to operate, greatly enhancing the playability and fun of the toy while ensuring connection strength.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0025] refer to Figures 1 to 4In this embodiment, the assembly toy connection structure includes a first connector 1 and a second connector 2. The first connector 1 has a protruding structure 11, and the outer surface of the protruding structure 11 forms a first wavy step 111. The second connector 2 has a recessed structure 21, and the inner surface of the recessed structure 21 forms a second wavy step 211 that cooperates with the first wavy step 111. The protruding structure 11 and the recessed structure 21 cooperate and lock to realize the detachable connection between the first connector 1 and the second connector 2. When the first connector 1 rotates relative to the second connector 2, the first wavy step 111 and the second wavy step 211 generate an interaction force, which releases the locking of the protruding structure 11 and the recessed structure 21, thereby separating the first connector 1 and the second connector 2.
[0026] The protruding structure 11 and the recessed structure 21 can be fitted with an interference fit, using the friction generated between them to connect the first connector 1 and the second connector 2. Alternatively, the fit can be a snap-fit connection. When it is necessary to separate the first connector 1 and the second connector 2, hold the first connector 1 and the second connector 2 with both hands respectively, and rotate one of the connectors or rotate the two connectors in opposite directions. At this time, the first wavy step 111 and the second wavy step 211 resist each other, following the wavy trend to separate the first connector 1 and the second connector 2. The wavy step can decompose the tangential force input when rotating the hand into radial and axial components, enabling the protruding structure 11 and the recessed structure 21 to separate and push against each other. The structure in this embodiment can firmly connect the first connector 1 and the second connector 2 while also separating them effortlessly. It is understood that the first connector 1 and the second connector 2 are merely examples. There may be multiple connectors, each of which may have only a protruding structure 11 or a recessed structure 21, or protruding structures 11 and recessed structures 21 on different surfaces of the same connector, and these can be in any combination, depending on the design of the connectors for different building toys.
[0027] refer to Figures 1 to 4In some embodiments, the first wavy step 111 and the second wavy step 211 have crests 3 and troughs 4, and slopes 5 located between the crests 3 and the troughs 4. Each crest 3 has the slope 5 between it and the adjacent trough 4. When the first connector 1 and the second connector 2 are connected, the crests 3 of the first wavy step 111 are aligned with the troughs 4 of the second wavy step 211. The angle of the slope 5 is 30° to 60°. This ensures that while maintaining effort-saving operation, the axial length of the protruding structure 11 and the recessed structure 21 is not too long or too short, thus making the overall size of the connector coordinated.
[0028] refer to Figures 1 to 4 In some embodiments, a smooth transition is used between the peak 3 and the trough 4 to make the separation smoother.
[0029] refer to Figures 1 to 4 In some embodiments, the first wave-shaped step 111 is evenly distributed circumferentially along the outer surface of the protruding structure 11 to form a continuous wave structure; the second wave-shaped step 211 is evenly distributed circumferentially along the inner surface of the recessed structure 21 to form a continuous wave structure. Therefore, the first connector 1 and the second connector 2 are not limited to a connection in one direction, and one of the peaks 3 of the first wave-shaped step 111 and any one of the troughs 4 of the second wave-shaped step 211 can be freely matched.
[0030] refer to Figures 1 to 4 In some embodiments, the thickness of the first wavy step 111 and the second wavy step 211 in the horizontal direction is equal, that is, the vertical distance from the outer surface of the first wavy step 111 to the intersection surface of the first wavy step 111 and the protruding structure 11 and the vertical distance from the outer surface of the second wavy step 211 to the intersection surface of the second wavy step 211 and the recessed structure 21 are equal, so that when the first wavy step 111 and the second wavy step 211 are engaged, the contact surfaces of the first wavy step 111 and the second wavy step 211 are completely fitted together. This makes the connection structure dimensions of different connectors uniform, and different connectors can be designed as needed to enrich the combination forms of the assembled toys.
[0031] refer to Figures 1 to 5In some embodiments, the top of the protruding structure 11 in the axial direction has a notch 112, and at least two segmented fins 113 extend inward from the notch 112. The bottom of the recessed structure 21 in the axial direction has a protrusion 212 that mates with the notch 112. A boss 2121 is provided on the outer side of the protrusion 212. The boss 2121 and the fins 113 can engage with each other to fix the first connector 1 and the second connector 2 together. The boss 2121 engages with the edge of the fins 113 to securely lock the first connector 1 and the second connector 2 together.
[0032] refer to Figures 1 to 5 In some embodiments, at least two of the fins 113 are brought closer together at the ends furthest from the notch 112. When the protrusion 212 is inserted into the notch 112, the boss 2121 causes the fins 113 to deform and move away from each other. When the boss 2121 passes over the fin 113, the fin 113 returns to its original shape, and the edge of the fin 113 engages with the boss 2121. By utilizing the elastic deformation characteristic of multiple fins 113, unidirectional engagement between the fins 113 and the protrusion 212 is achieved, making the connection between the first connector 1 and the second connector 2 easy and effortless, while also preventing separation.
[0033] refer to Figures 1 to 5 In some embodiments, the head of the protrusion 212 is provided with a guide slope 21225. This design allows the guide slope 21225 to slide relative to the fin 113 during the connection process, which can reduce friction and make the process of connecting the first connector 1 and the second connector 2 smoother and less strenuous.
[0034] refer to Figure 3 and Figure 5 In some embodiments, the head of the protrusion 212 is provided with a groove 2123. When subjected to compressive force, the groove 2123 becomes smaller, and the protrusion 212 deforms toward the axis. Even with a small force, the first connector 1 and the second connector 2 can be connected and locked together. Even children with less strength can operate it easily.
[0035] refer to Figures 1 to 5 In some embodiments, the first connector 1 and the second connector 2 are made of plastic, preferably ABS (acrylonitrile-butadiene-styrene copolymer) or PA (polyamide, commonly known as nylon). ABS is easy to process, has high hardness and good dimensional stability, and is suitable for high-precision assembly toys. PA has good wear resistance and high fatigue resistance, which can improve the service life of assembly toys.
[0036] The connection structure of this invention, through the interlocking wave-shaped steps on the protruding structure 11 and the recessed structure 21, effectively overcomes the shortcomings of traditional interference fit connections, which are laborious to assemble and disassemble, and complex locking mechanisms that are cumbersome to operate. It achieves a stable connection simply by plugging it in, ensuring the reliability of the assembled model; separation is achieved through rotation, guided by the wavy step slope 5, allowing children to easily disassemble it, significantly reducing the difficulty of operation and the strength required. This structure is intuitive and simple to operate, greatly enhancing the playability and fun of the toy while ensuring connection strength.
