Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper head. Background Art

[0002] A zipper with a guard is an innovative product designed to enhance zipper security. This type of zipper incorporates a guard, a feature of traditional zipper teeth. Its primary purpose is to prevent foreign objects or tools from being inserted through the interlocking area between the teeth, potentially opening or damaging the zipper. The guard is typically made of a strong, wear-resistant material, effectively resisting prying and abrasion, providing a solid protective barrier for the zipper.

[0003] However, in actual use, this type of chain tooth with a baffle has also exposed some problems. To ensure the smooth movement of the zipper pull, the baffle is usually set relatively high to avoid interference with the outside of the zipper pull. However, this design also weakens the protective effect of the baffle to a certain extent. Because when the baffle is positioned high, it cannot tightly cover the chain tooth part of the chain tooth, leaving a large gap with the potential risk of being inserted and pried open by external tools. Although this design trade-off ensures the free movement of the zipper pull, it also sacrifices the protective performance of the zipper baffle to a certain extent. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention proposes a zipper head that can solve the problem that the baffle position of the chain teeth with a baffle is set too high so as not to affect the movement of the zipper head, resulting in a weakened protective effect.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a zipper head, comprising a zipper head body. The zipper head body is further provided with a tooth body passing portion and a baffle passing portion. The baffle passing portion is located above the tooth body passing portion, and the tooth body passing portion and the baffle passing portion are communicated with each other.

[0007] The preferred technical solution of the present invention is that it includes a middle plate body, which is located in the zipper head body. The zipper head body includes an upper plate body, a lower plate body, a first upper side plate and a guide column. The upper plate body and the middle plate body are connected by the first upper side plate, and the lower plate body and the middle plate body are connected by the guide column.

[0008] An optimal technical solution of the present invention is that the zipper head body and the middle plate are integrally formed.

[0009] A preferred technical solution of the present invention is that the material of the zipper head body and the middle plate is ABS.

[0010] An optimal technical solution of the present invention is that a pull tab is further provided on the upper portion of the zipper head body.

[0011] A preferred technical solution of the present invention is that a wear-resistant coating is provided on the surface of the zipper head body.

[0012] Beneficial effects of the utility model:

[0013] The utility model proposes a zipper head, which is provided with an additional baffle passage portion for the baffle of the chain teeth to pass through above the original chain tooth body passage portion, and the two parts are connected. This design allows the baffle, which was originally set at a higher position due to protection needs but also to meet the passage of the zipper head, to pass through the baffle passage portion, without directly interfering with the outside of the zipper head body and lowering the position of the baffle. Under such a configuration, the movement of the chain tooth body within the zipper head body is not hindered in any way, maintaining the original smoothness and efficiency. Due to the relatively low height position, the baffle can more effectively play its protective role, preventing external forces from directly acting on the fragile chain tooth area, greatly enhancing the overall safety of the zipper.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] Example 1

[0021] A zipper head provided in this embodiment, such as Figure 1-2As shown, the pull tab is omitted for ease of illustration. The zipper slider body 1 includes a zipper element passage 2 and a baffle passage 3. The baffle passage 3 is located above the zipper element passage 2 and is interconnected. In this structure, the zipper slider body not only includes a zipper element passage, through which the elements pass smoothly, but also uniquely incorporates a baffle passage located above the zipper element passage, with the two sections interconnected. This design allows the baffle, which would otherwise have to be positioned higher for protection purposes but still allow the zipper slider to pass, to pass through the baffle passage without having to lower the baffle to interfere directly with the exterior of the zipper slider body. This configuration allows the elements to move unimpeded within the slider body, maintaining their original smoothness and efficiency. Due to its relatively low height, the baffle can more effectively protect the vulnerable element area, preventing external forces from directly acting on it, significantly enhancing the overall safety of the zipper. Therefore, this solution ensures the flexible operation of the zipper head and enhances the protective effectiveness of the baffle by rationally arranging the spatial relationship between the chain tooth body passing part and the baffle passing part, achieving a perfect balance between protection and functionality.

[0022] Preferably, it includes a middle plate 4, which is located in the zipper head body 1. The zipper head body 1 includes an upper plate 11, a lower plate 12, a first upper side plate 14 and a guide post 13. The upper plate 11 and the middle plate 4 are connected by the first upper side plate 14, and the lower plate and the middle plate 4 are connected by the guide post 13. This preferred solution has a simple structure. The structure of the chain tooth body passing part and the baffle passing part is formed only by adding a middle plate. In addition, the middle plate is located in the zipper head body and serves as the core support structure. It not only enhances the overall stability of the zipper head, but also optimizes the stress distribution between the various components, reducing the risk of deformation or damage caused by long-term use or improper operation. The design of connecting the upper plate and the middle plate through the first upper side plate and connecting the lower plate and the middle plate through the guide post ensures the stability and precision of the zipper head during sliding, reducing shaking and jamming.

[0023] Preferably, the zipper pull body 1 and the central plate 4 are integrally molded. This integrated molding not only simplifies the production process and reduces production costs, but more importantly, significantly improves the overall strength and durability of the zipper pull. Through one-shot injection molding, the gaps and looseness that can occur with traditional assembly methods are avoided. Furthermore, this integrated molding technology ensures the smoothness and aesthetics of the zipper pull, enhancing the overall quality of the product. Furthermore, this design facilitates customized production of zipper pulls to meet the individual needs of different customers.

[0024] Preferably, the zipper slider body 1 and the middle plate 4 are made of ABS. ABS has excellent impact strength, heat resistance, and chemical resistance, and can withstand the friction, collisions, and extrusion experienced during daily use, ensuring the long-term stable operation of the zipper slider. ABS also has excellent processability and is easily injection molded, meeting the design requirements of complex structures. Its smooth surface also facilitates subsequent surface treatments such as spraying and electroplating. Furthermore, ABS is environmentally friendly, meeting modern consumers' expectations for green and sustainable products.

[0025] Preferably, a pull tab is also provided on the upper portion of the zipper slider body 1. Adding a pull tab to the upper portion of the zipper slider body is a key design feature that enhances the slider's ease of operation and user experience. As the component through which the user directly interacts with the zipper slider, the pull tab's shape, size, and material directly impact operational comfort and efficiency. By rationally designing the pull tab's shape, such as adopting an ergonomically curved design, hand fatigue can be reduced and operational precision improved. The pull tab can also serve as a decorative element, enhancing the product's overall aesthetics.

[0026] Preferably, the surface of the zipper head body 1 is provided with a wear-resistant coating. The wear-resistant coating is usually made of a polymer material or a ceramic material, has extremely high hardness and wear resistance, can effectively resist friction and wear in daily use, and protect the zipper head body from damage. At the same time, the wear-resistant coating can also improve the smoothness of the zipper head surface, reduce sliding resistance, and make the zipper head smoother and more silent during sliding. In addition, the wear-resistant coating also has certain anti-corrosion properties, which can prevent the zipper head from being damaged due to long-term exposure to humid and corrosive environments. In this embodiment, the wear-resistant coating is formed on the surface of the zipper head by spraying PTFE.

[0027] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
