Description

Technical Field

[0001] This utility model proposes a child-friendly auxiliary chopstick, relating to the field of children's products, specifically a child-friendly anti-misalignment auxiliary chopstick. Background Technology

[0002] Currently, most children's chopstick training aids on the market consist of three parts: the chopstick body, the aid, and the anti-misalignment structure. They help guide children in using chopsticks. The aid connects and positions the two chopsticks, and the structure on the aid guides the hand posture and direction of force during use.

[0003] Although existing chopsticks can help children learn to use chopsticks, as the angle between the two chopsticks decreases, the elasticity of the aid increases accordingly. However, children's hand strength is insufficient, making it difficult to control the force when using existing chopsticks, which can easily lead to misalignment. The anti-misalignment component design of existing aids also poses a risk of detachment and accidental ingestion.

[0004] To address the above issues, those skilled in the art have proposed a child-proof chopsticks design with a more scientifically designed structure to help guide children in learning to use chopsticks and avoid the problem of small components easily detaching. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a child-proof anti-misplacement auxiliary chopstick. This product features an integrated design, reducing the number of product parts and thus lowering the probability of product loss. A single component can also perform the functions. Through the two-stage guiding design of the guide block and the limiting block for the pin, the limiting strength changes accordingly at different stages, preventing the protruding structure from falling off and causing accidental ingestion.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a child-proof chopstick, comprising a chopstick body and a connector sleeved on the side of the chopstick body, wherein the two parts of the chopstick body are integrated by the connector to reduce the difficulty of use.

[0007] However, the connector in the prior art uses silicone springback for reset, which causes the elastic force to increase as the angle between the two parts of the chopstick body decreases. This can easily cause the chopstick body to misalign. Therefore, corresponding anti-misalignment components are designed. However, these small components are easy to fall off and cause accidental ingestion.

[0008] To address the above issues, those skilled in the art have proposed improvements to the existing connector. To avoid the risk of accidental ingestion caused by small parts falling off, all structures of this device are made of silicone and are integrally integrated with the connector.

[0009] A pin is fixed to the inner wall of the connector, and a guide block is fixed to the inner wall of the connector corresponding to the pin. When the two parts of the chopsticks are clamped, the pin is guided by the guide block.

[0010] However, this guiding structure cannot adjust the guiding effect according to the change of the elasticity of the connector. The guiding effect it can provide is fixed and the effect is not good. Therefore, further improvement is needed.

[0011] The end of the guide block is fixed with a limiting block, which is an extension of the guide block. Together with the guide block, the limiting block not only provides a better initial guiding effect for the ejector pin, but also plays a primary and secondary guiding role at different stages.

[0012] As the two sides of the connector close, the ejector pin is guided once along the limiting block and then a second time along the guide block. The strength of the two guidances changes accordingly with the spacing between the structures and the friction, making it more suitable for error prevention when the elasticity of the connector changes.

[0013] Preferably, the ejector pin is a trapezoidal block that gradually increases in size along the direction of the connector towards the guide block, and the frictional force between the ejector pins with the trapezoidal structure can change with the advance distance.

[0014] The two guide blocks are symmetrically fixed on both sides of the ejector pin. The two guide blocks apply friction to the ejector pin from both sides and guide the ejector pin's advance direction.

[0015] Preferably, the limiting block and the ejector pin are in an interference fit. Here, the interference fit means that the total length of the guide block and the limiting block exceeds the end of the ejector pin, so that the guide block has a guiding effect on the ejector pin in the initial state.

[0016] The area of ​​the guide block facing the ejector pin gradually increases from the end to the root. The gradually increasing contact area increases the friction between them. When the friction increases, it can ensure that the ejector pin moves along the direction of the guide block.

[0017] Preferably, a circular air cushion is fixed to the end of the ejector pin, and an air hole is opened through the side of the circular air cushion. The circular air cushion can squeeze out the internal air as it contacts the inner wall of the connector, thereby further changing the angle of the connector to adapt to the use when the chopstick body and the connector are positioned at different lengths.

[0018] Preferably, the connector has an arc-shaped groove on its side wall, which is provided in accordance with the limiting block. After the connector is closed to a certain extent, it can cooperate with the ejector pin and the guide block for secondary guidance, which is more stable than a single guide structure.

[0019] The inner bottom wall of the arc-shaped groove is set as a plane, and the side of the limiting block facing the inner bottom wall of the arc-shaped groove is set as an inclined surface. As the limiting block moves along the arc-shaped groove, the friction between the limiting block and the inner wall of the arc-shaped groove gradually increases, which can also achieve a good exercise effect.

[0020] Preferably, the connector is provided with a finger ring and an arc-shaped groove on its left and right sides, respectively, to help the user position their fingers on the device.

[0021] Preferably, a gap of 0.5-2 mm is reserved between the ejector pin and the guide block and the limiting block. This gap can ensure both sliding and guiding function.

[0022] This utility model discloses a child-preventing misalignment auxiliary chopstick, which has the following beneficial effects:

[0023] 1. This child-friendly anti-misalignment chopsticks is designed to address the limitations of existing silicone training aids for children. This product integrates the aid and anti-misalignment features into a single design, ensuring functionality while reducing the number of parts and thus lowering the probability of loss. A single component performs all functions, preventing dirt and grime buildup. The aid has a curved groove on the right side for the child's hand, providing a secure and guiding position to help children use chopsticks correctly, while also making it easier to use. The larger curved groove provides greater tolerance for hand misalignment.

[0024] 2. This child-resistant anti-misalignment chopstick features a semi-circular pin structure at the bottom center that, through contact with the inner side on the right, effectively restricts the forward and backward movement of the chopstick using the friction of the silicone material. A gap of approximately 0.8mm exists between the two, and the friction between them, along with the silicone material, restricts the left and right twisting of the chopstick, thus achieving an anti-misalignment effect within a lateral range. Because children's hand muscles are not fully developed and their force application is uneven, this gap provides a certain tolerance space. This distance ensures better contact between the two parts during use, preventing excessive friction that could lead to strenuous use and maximizing the anti-misalignment effect through contact and friction.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model discloses a child-preventing misalignment auxiliary chopstick;

[0032] According to the appendix Figure 1 As shown, it includes chopstick body 1 and connector 2 which is sleeved on the side of chopstick body 1. The two parts of chopstick body 1 are formed into a whole through connector 2 to reduce the difficulty of use.

[0033] However, the existing connector 2 uses silicone springback for reset, which causes the spring force to increase as the angle between the two parts of the chopstick body 1 decreases. This can easily cause misalignment of the chopstick body 1. Therefore, corresponding anti-misalignment components are designed. However, these small components are easy to fall off and cause accidental ingestion.

[0034] In response to the above problems, those skilled in the art have proposed improvements to the existing connector 2. To avoid the risk of accidental ingestion caused by small parts falling off, all structures of this device are made of silicone material and are integrated with the connector 2.

[0035] According to the appendix Figure 2 As shown, a pin 3 is fixed on the inner wall of connector 2, and a guide block 4 is fixed on the inner wall of connector 2 corresponding to the pin 3. When the two parts of the chopstick body 1 perform a clamping action, the pin 3 is guided by the guide block 4.

[0036] However, this guiding structure cannot adjust the guiding effect according to the change of the elasticity of connector 2. The guiding effect it can provide is fixed and the effect is not good. Therefore, further improvement is needed.

[0037] The end of the guide block 4 is fixed with a limiting block 5. The limiting block 5 is an extension of the guide block 4. Together with the guide block 4, it not only provides a better initial guiding effect for the ejector pin 3, but also plays a primary and secondary guiding role at different stages.

[0038] As the two sides of connector 2 come together, the ejector pin 3 is guided once along the limiting block 5 and then guided a second time along the guide block 4. The strength of the two guidances changes accordingly with the spacing between the structures and the change of friction, making it more suitable for error prevention when the elasticity of connector 2 changes.

[0039] The ejector pin 3 is a trapezoidal block that gradually increases in size along the direction from the connector 2 to the guide block 4. The trapezoidal ejector pin 3 can change the magnitude of the friction force between them as the advance distance changes.

[0040] Two guide blocks 4 are symmetrically fixed on both sides of the ejector pin 3. The two guide blocks 4 apply friction to the ejector pin 3 from both sides and guide the ejector pin 3 in the advancing direction.

[0041] The limiting block 5 and the ejector pin 3 are interference-fitted. Here, interference fit means that the total length of the guide block 4 and the limiting block 5 exceeds the end of the ejector pin 3, and it has a guiding effect on the ejector pin 3 in the initial state.

[0042] The area of ​​the guide block 4 facing the ejector pin 3 gradually increases from the end to the root. The gradually increasing contact area increases the friction between them. When the friction increases, it can ensure that the ejector pin 3 advances along the direction of the guide block 4.

[0043] According to the appendix Figure 3 As shown, a circular air cushion 6 is fixed to the end of the ejector pin 3. An air hole is opened through the side of the circular air cushion 6. The circular air cushion 6 can squeeze out the internal air as it contacts the inner wall of the connector 2, thereby further changing the angle of the connector 2 to adapt to the use when the chopstick body 1 and the connector 2 are positioned at different lengths.

[0044] The side wall of connector 2 is provided with an arc-shaped groove 7, which is set to correspond to the limiting block 5. After connector 2 is closed to a certain extent, it can cooperate with the ejector pin 3 and the guide block 4 to provide secondary guidance, which is more stable than a single guide structure.

[0045] The inner bottom wall of the arc-shaped groove 7 is set as a plane, and the side of the limiting block 5 facing the inner bottom wall of the arc-shaped groove 7 is set as an inclined surface. As the limiting block 5 moves along the arc-shaped groove 7, the friction between the limiting block 5 and the inner wall of the arc-shaped groove 7 gradually increases, which can also achieve a good exercise effect.

[0046] The connector 2 has a finger ring 8 and an arc-shaped groove 9 on its left and right sides, respectively, to help the user position their fingers on the device.

[0047] A gap of 0.5-2 mm is reserved between the ejector pin 3, the guide block 4 and the limiting block 5. This gap can ensure both sliding and guiding function.

[0048] This child-friendly anti-misalignment chopsticks is designed to address the limitations of existing silicone training aids for children. This product integrates the aid and anti-misalignment features into a single design, ensuring functionality while reducing the number of parts and thus lowering the probability of loss. A single component performs all functions, preventing dirt and grime buildup. The aid features a curved groove (9) on the right side, providing a secure placement for the child's hand, guiding them to use chopsticks correctly and making them easier to use. The larger curved groove (9) also increases the margin for error in hand placement.

[0049] Furthermore, the semi-circular pin 3 structure in the lower center of the assist device can effectively restrict the forward and backward movement of the assist device by contacting the inner side on the right side and using the friction of the silicone material. There is a gap of about 0.8mm between the two. By using the mutual contact and friction between the two and the friction of the silicone material, the left and right twisting of the assist device is restricted, thereby achieving the error prevention effect in the left and right space range.

[0050] Because children's hand muscles are not fully developed and their force is uneven, a certain margin of error is provided between the two. This distance ensures that the two can make better contact during the use of the assistive device, so that it will not be difficult to use due to excessive friction, and it can also better achieve the contact friction error prevention effect.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
