[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment provides a zipper tooth tape, such as Figures 1-4 As shown, the zipper belt is omitted from the diagram for ease of display. The zipper belt includes a zipper belt and zipper teeth. The zipper teeth are connected to the zipper belt by a snap-fit ​​mechanism. The zipper belt includes a left zipper belt and a right zipper belt. Compared to the right zipper teeth, the left zipper tooth on one side only has a tooth body 1, while the left zipper tooth on the other side includes a tooth body 1 and a blocking member 2. One end of the blocking member 2 is connected to the tooth body 1. The second groove 14 of the tooth body 1 is used for snap-fitting with the zipper belt. The stop portion 21 of the blocking member 2 is located above the tooth body 1 and extends past the tooth portion 11 of the tooth body 1. In this embodiment, the stop portion 21 of the left zipper tooth extends to the other end of the right zipper tooth. In this design, the tooth body, as the basic structural unit of the zipper, bears the important responsibility of engagement and connection. The design of the blocking member effectively supplements and strengthens the tooth body, with one end tightly connected to the tooth body, ensuring the stability of the structure. The blocking part is cleverly positioned above the zipper tooth body and extends to cover the teeth. This design not only provides a solid physical barrier for the teeth, effectively preventing external tools from inserting and prying them from above or the side, but also increases the width of the interlocking area through the extended part of the blocking part, greatly increasing the difficulty of prying open. Therefore, this zipper tooth technology solution, through the innovative combination of the blocking part and the zipper tooth body, significantly improves the zipper's anti-prying ability and overall durability, effectively solving the safety hazards currently faced by zipper products in use. It should be noted that, in addition to the technical solution of this embodiment, where the blocking part extends beyond the teeth to reach the right zipper tooth to form a covering protection, the left and right zipper teeth can also have symmetrical structures, allowing their blocking parts to extend towards the teeth and interlock to form another type of covering protection.

[0028] Preferably, the shielding piece 2 is in an L-shaped structure. The L-shaped structure is characterized in that it can provide more comprehensive and effective shielding protection. On the one hand, the long arm part of the L-shaped structure can cover the top of the tooth part of the tooth body, effectively preventing external tools from being inserted from above to pry the tooth engagement part, thereby greatly reducing the risk of damage to the zipper. On the other hand, the short arm part of the L-shaped structure is close to one side of the tooth body, forming an additional protective barrier. Even if someone tries to damage it from the side, it will be difficult to succeed because of the existence of this barrier. In addition, the design of the L-shaped structure also considers the balance between aesthetics and practicality, without adding too much volume and weight, but providing sufficient protection effect.

[0029] The connection between the tooth body and the shielding piece can be achieved by metal stamping or welding for metal materials, or by injection molding for non-metallic polymer materials. Preferably, the tooth body 1 and the shielding piece 2 of the present embodiment are injection molded. Compared with the traditional split design, the one-piece design avoids the security risks caused by loose or damaged connecting parts. At the same time, the one-piece design also simplifies the production process, making the molding process convenient, especially suitable for complex appearance structures, improving production efficiency and reducing production cost.

[0030] Preferably, the materials of the tooth body 1 and the shielding piece 2 are nylon. Nylon is an excellent engineering plastic with high strength, high wear resistance, high toughness, and good corrosion resistance. These characteristics make nylon an ideal material for manufacturing teeth. First, the high strength and wear resistance of nylon can ensure that the teeth are not easily damaged during use, thereby prolonging the service life of the product. Second, nylon has good toughness and can withstand large deformation without breaking, which helps to improve the anti-prying ability of the teeth.

[0031] Preferably, the blocking part 21 is in a cuboid structure. The cuboid structure of the blocking part, which is regular in shape and compact, can more effectively cover the chain tooth part of the chain tooth body, forming a solid protective barrier. This structure helps to prevent external tools from being inserted from above or the side to pry the chain tooth, thereby greatly reducing the risk of the zipper being damaged. In addition, the cuboid structure of the blocking part presents a stable and atmospheric beauty in vision, which can be well matched with various clothing and bag products, and improves the overall product grade. More importantly, this structure also enables the blocking part to be evenly distributed when stressed, reducing the possibility of stress concentration and prolonging the service life of the chain tooth. Further, the outer surface of the blocking part 21 is provided with a decorative layer. In the design of the chain tooth, the addition of a decorative layer to the outer surface of the blocking part is an extremely creative and practical improvement. The presence of the decorative layer not only enriches the visual effect of the chain tooth, but also improves the overall appearance and market competitiveness of the product. By using different materials, colors and patterns, the decorative layer can give the chain tooth a unique personality and style, meeting the needs of consumers for product individualization.

[0032] Preferably, the chain tooth part 11 is provided with a first groove 12, and the left and right sides of the chain tooth part 11 are provided with a clamping protrusion 13. The presence of the first groove enables the chain tooth to be more tightly engaged when closed, thereby improving the sealing and stability of the zipper. At the same time, the first groove can also increase the friction between the chain teeth, making the zipper more smooth and stable when opening and closing. The clamping protrusions on the left and right sides of the chain tooth part further enhance the engagement force and anti-prying ability of the chain tooth. These protrusions can tightly cooperate with the corresponding parts of the adjacent chain tooth, forming a strong engagement lock that effectively prevents external tools from prying the chain tooth from the side. Further, the first groove 12 and the clamping protrusion 13 are located on the same horizontal plane. When the first groove and the clamping protrusion are on the same horizontal plane, they can more accurately match and lock with each other, effectively preventing accidental falling or sliding of the chain tooth during transmission, thereby improving the safety and stability of the entire transmission system.

[0033] Preferably, the blocking parts 21 of adjacent chain teeth on the zipper tooth belt are in close contact with each other. This design greatly enhances the sealing and safety of the zipper. In traditional zippers, the gaps between the chain teeth often become potential channels for external foreign matter to enter, and may also become weak points for prying the zipper. However, the blocking parts of adjacent chain teeth in close contact with each other effectively fill these gaps, forming a continuous and seamless protective layer that not only prevents the intrusion of external factors such as dust and moisture, but also significantly improves the ability of the zipper to resist external prying, making the zipper more stable and durable. In addition, in combination with the decorative layer design in the above embodiments, the crotch parts of the chain teeth can be combined to form a coherent picture, making the product not only improve the protection and safety, but also have a unique beauty.

[0034] The utility model discloses the description through the preferred embodiment, and the person skilled in the art knows that various changes or equivalent replacement can be made to these features and embodiments without departing from the spirit and scope of the utility model. The utility model is not limited by the specific embodiments disclosed here, and other embodiments falling within the claims of the present application all belong to the scope of protection of the utility model.
