Description

Technical Field

[0001] This invention relates to the field of luggage plastic frame, zipper and case shell fixing technology, and in particular to a highly robust luggage zipper and case shell fixing structure and method. Background Technology

[0002] Suitcases are widely used in daily life and travel, especially those with zippers. The zipper fastening structure directly affects ease of use and product durability. Currently, suitcase zippers are typically fastened using either sewing or adhesive methods. This involves sewing the zipper frame onto the suitcase shell or applying adhesive to secure it. While this method is simple and initially ensures good zipper fastening, its limitations have become increasingly apparent with rising environmental standards, increased production efficiency, and greater demands for product durability. These limitations are particularly evident in the design of the zipper mounting frame.

[0003] 1. Insufficient durability and reliability: The adhesive application method has certain limitations in zipper fixing structures, especially in the zipper mounting frame. With increased use, the adhesive bonding strength is easily affected by external environmental factors such as temperature and humidity, potentially causing the zipper fabric edge to loosen or even detach. Furthermore, adhesive aging is also a critical factor; after prolonged use, the adhesive will gradually lose its stickiness or even crack, severely affecting the zipper's stability and the suitcase's lifespan.

[0004] 2. Lack of Environmental Friendliness: The adhesives used in the dispensing process often contain harmful chemicals such as formaldehyde. Even after high-temperature curing, these harmful components may still remain in the finished product and are difficult to completely volatilize. This not only pollutes the environment, but also, during use, especially in extreme environments such as high temperature and high humidity, these chemicals may be released, affecting the health of users. With the increasing market demand for environmentally friendly products, traditional dispensing processes clearly cannot meet the requirements of green and environmentally friendly standards.

[0005] 3. Complex and inefficient production process: The adhesive fixing process for zippers involves multiple complex steps, including adhesive application, heating, curing, and cooling. First, the adhesive application process requires precise control of the amount of adhesive used to avoid excess adhesive affecting the product's appearance. Second, the adhesive curing process is time-consuming, increasing the production cycle. Finally, the cooling step further delays the production schedule. The complexity of these steps not only increases production costs but also reduces production efficiency, making it difficult to meet the luggage industry's demand for high-efficiency production.

[0006] Therefore, the technical problem to be solved by this invention is how to provide a luggage zipper fixing structure that is environmentally friendly, has a simplified process, and can ensure the zipper is firmly fixed. Summary of the Invention

[0007] The technical problem solved by the present invention is to address the deficiencies in the prior art by providing a highly robust luggage zipper fixing structure and method, thereby solving the problems of poor environmental performance, complex processes, and insufficient fixing strength of existing luggage zipper fixing methods mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0009] A highly robust luggage zipper fixing structure includes a zipper mounting frame, a zipper fabric edge positioning groove, a first positioning hole, a second positioning hole, and rivets;

[0010] The zipper mounting frame is used for secure connection to the suitcase shell;

[0011] One side of the zipper mounting frame is provided with a zipper fabric edge positioning groove that matches the zipper fabric edge. The zipper mounting frame is provided with first positioning holes that penetrate the zipper fabric edge positioning groove evenly distributed along the length of the zipper fabric edge.

[0012] The zipper fabric edge, which mates with the zipper edge positioning groove, is evenly provided with second positioning holes that mate with the first positioning hole; rivets pass through the first and second positioning holes to rivet the zipper mounting frame and the zipper fabric edge together.

[0013] As a further embodiment of the present invention, a third positioning hole is provided on the suitcase shell, and rivets pass through the first positioning hole, the second positioning hole and the third positioning hole, so that the zipper mounting frame, the zipper edge and the suitcase shell are riveted together.

[0014] As a further embodiment of the present invention, the zipper mounting frame is provided with a limiting hole that communicates with the positioning groove of the zipper fabric edge, the positioning post is matched with the limiting hole, and one side of the zipper fabric edge extends into the limiting hole and is fixedly connected to the side of the positioning post.

[0015] As a further embodiment of the present invention, the limiting hole is located at the bottom of the groove of the zipper edge positioning groove.

[0016] As a further embodiment of the present invention, the positioning post is a reinforcing bar or a rubber rod.

[0017] As a further aspect of the present invention, the end cross-sectional shape of the glue rod is circular or rectangular.

[0018] As a further embodiment of the present invention, the zipper edge positioning groove and the limiting hole respectively penetrate the front end and / or rear end of the zipper mounting frame.

[0019] A highly robust method for securing a suitcase zipper includes:

[0020] Connect the zipper mounting frame to the suitcase shell, or prepare the zipper mounting frame in advance to connect to the suitcase shell;

[0021] A zipper edge positioning groove is provided on one side of the zipper mounting frame to accommodate the zipper edge;

[0022] Corresponding positioning holes are formed in the corresponding parts of the zipper edge and the zipper mounting frame for alignment;

[0023] By passing rivets through the positioning holes of the zipper mounting frame and the positioning holes of the zipper fabric edge, the zipper mounting frame and the zipper fabric edge are riveted and fixed together.

[0024] The luggage shell is fixedly connected to the zipper mounting frame or zipper edge to achieve overall fixation.

[0025] As a further aspect of the present invention, the following steps are also included:

[0026] Provide fabric reinforcement or glue sticks as positioning posts;

[0027] A limiting hole is set at the bottom of the groove of the zipper mounting frame, and a corresponding positioning post is formed on the edge of the zipper fabric;

[0028] Insert the positioning pin into the limiting hole so that a portion of the zipper edge extends into the limiting hole, thereby securely embedding the zipper edge into the zipper edge positioning groove.

[0029] As a further aspect of the present invention, the following steps are also included:

[0030] A third positioning hole is provided on the suitcase shell;

[0031] By rivets passing through the first positioning hole of the zipper mounting frame, the second positioning hole of the zipper fabric edge, and the third positioning hole of the suitcase shell in sequence, the zipper mounting frame, the zipper fabric edge, and the suitcase shell are fixed together.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The zipper mounting frame and zipper edge are riveted together, providing a more stable and durable fixing method. In some embodiments, the zipper mounting frame, zipper edge, and suitcase shell are further secured with rivets, making the entire structure more robust. This effectively avoids the problem of loosening or falling off due to environmental factors caused by traditional glue fixing methods, greatly extending the service life of the suitcase.

[0034] 2. By replacing traditional adhesive bonding with physical riveting and limiting structures, the use of glue is significantly reduced, thereby effectively lowering the release of harmful substances such as formaldehyde during production, making it more environmentally friendly. This design not only meets current stringent environmental protection requirements but also avoids the problem of loosening due to glue aging or environmental changes, greatly improving the lifespan and stability of the suitcase.

[0035] 3. A limiting hole is set at the bottom of the groove of the zipper mounting frame, and a corresponding positioning post (such as a fabric reinforcement or glue stick) is formed on the zipper fabric edge, so that a part of the zipper fabric edge is embedded in the limiting hole, which further enhances the fixing effect between the zipper fabric edge and the zipper mounting frame.

[0036] 4. The combination of the positioning pin, the limiting hole, and the rivet not only forms a double physical fixation with the rivet, significantly improving the stability of the zipper edge, but also avoids the risk of displacement or tearing during use. At the same time, it effectively disperses the force on the zipper and reduces wear problems under single-point force.

Detailed Implementation

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figure 1 —9. In this embodiment of the invention, a highly robust luggage zipper fixing structure includes a zipper mounting frame 1, a zipper fabric edge positioning groove 2, a first positioning hole 3, a second positioning hole 4, and a rivet 5.

[0052] The zipper mounting frame 1 is used to fix and connect with the suitcase shell 6; a zipper edge positioning groove 2 is provided on one side of the zipper mounting frame 1, and first positioning holes 3 that penetrate the zipper edge positioning groove 2 are evenly distributed on the zipper mounting frame 1.

[0053] The zipper fabric edge 8, which mates with the zipper fabric edge positioning groove 2, is evenly provided with second positioning holes 4 that mate with the first positioning hole 3; the rivet 5 passes through the first positioning hole 3 and the second positioning hole 4 to rivet the zipper mounting frame 1 and the zipper fabric edge.

[0054] The suitcase shell 6 has a third positioning hole 7. Rivets 5 pass through the first positioning hole 3, the second positioning hole 4, and the third positioning hole 7, connecting the zipper mounting frame 1, the zipper edge, and the suitcase shell 6 together. The zipper mounting frame 1 has a limiting hole 9 that communicates with the zipper edge positioning groove 2. The positioning post 10 engages with the limiting hole 9, and one side of the zipper edge extends into the limiting hole 9 and is fixedly connected to the side of the positioning post 10.

[0055] The limiting hole 9 is located at the bottom of the zipper edge positioning groove 2. The positioning post 10 is a fabric reinforcement or a glue rod. The end cross-section of the glue rod is circular or rectangular. The zipper edge positioning groove 2 and the limiting hole 9 respectively penetrate the front end and / or rear end of the zipper mounting frame 1; as shown... Figure 9 As shown, in the extended embodiment of the present invention, an explosion-proof limiting protrusion 15 can be provided at the position inside the zipper mounting frame 1, so as to provide explosion-proof limiting support to the lower part of the flexible zipper through the rigid explosion-proof limiting protrusion 15. These are all extended embodiments known to those skilled in the art.

[0056] This invention discloses a highly robust zipper fixing structure for suitcases, ultimately forming a zipper mounting frame 1 composed of two components. The structure includes two frames respectively fixedly connected to the suitcase shell 6, each frame used to fix one side of the zipper. Through a reasonable design and connection method, a robust fixation between the zipper and the suitcase shell 6 is achieved.

[0057] Specifically, the zipper mounting frame 1 consists of two independent frame components, which are respectively installed on both sides of the bottom and lid of the suitcase 6. Each frame component has a zipper edge positioning groove 2, and the two sides of the zipper edge are respectively embedded in the positioning groove of each frame component and fixed by positioning holes and rivets 5. The first positioning hole 3 on each frame is aligned with the second positioning hole 4 on the zipper edge, and the rivets 5 pass through the third positioning hole 7 on the frame, zipper edge, and suitcase shell to achieve a stable connection between the two sides of the zipper edge and their respective frame and shell.

[0058] In addition, the frame assembly design includes the combined use of limiting holes 9 and positioning posts 10. This limiting structure further enhances the fixing strength of the zipper edge, preventing displacement or tearing during use. The frame assembly is combined with the plastic frame to form an integral structure, which is then assembled with the suitcase shell 6 to ensure the overall structural strength and durability.

[0059] Ultimately, the two frame components, together with the zipper and case shell, form a complete one-piece zipper mounting frame. This structure not only improves assembly efficiency but also reduces production costs and simplifies the assembly process by eliminating traditional sewing and gluing processes, while ensuring a strong connection between the zipper structure and the case shell and reliable long-term use.

[0060] A highly robust method for securing a suitcase zipper includes:

[0061] Connect the zipper mounting frame 1 to the suitcase shell 6, or prepare the zipper mounting frame 1 in advance to connect with the suitcase shell 6;

[0062] A zipper edge positioning groove 2 is provided on one side of the zipper mounting frame 1 to accommodate the zipper edge; corresponding positioning holes are formed in the corresponding parts of the zipper edge and the zipper mounting frame 1 to facilitate alignment; the zipper mounting frame 1 is riveted and fixed to the zipper edge by passing rivets 5 through the positioning holes of the zipper mounting frame 1 and the zipper edge.

[0063] The suitcase shell 6 is fixedly connected to the zipper mounting frame 1 or the zipper edge to achieve overall fixation.

[0064] It also includes the following steps:

[0065] Provide a fabric reinforcement or glue stick as a positioning post 10; set a limiting hole 9 at the bottom of the groove of the zipper mounting frame 1, and form a corresponding positioning post 10 on the zipper fabric edge; insert the positioning post 10 into the limiting hole 9, so that a part of the zipper fabric edge protrudes into the limiting hole 9, so as to securely embed the zipper fabric edge into the zipper fabric edge positioning groove 2.

[0066] It also includes the following steps:

[0067] A third positioning hole 7 is provided on the outer shell 6 of the suitcase;

[0068] By passing rivets 5 sequentially through the first positioning hole 3 of the zipper mounting frame 1, the second positioning hole 4 of the zipper fabric edge, and the third positioning hole 7 of the suitcase shell 6, the zipper mounting frame 1, the zipper fabric edge, and the suitcase shell 6 are fixed together.

[0069] In an extended embodiment, a zipper mounting frame 1 is provided with a zipper holder 11, which supports and secures the zipper 12 inside the suitcase. One side of the zipper 12 is fixedly connected to a post 13 that mates with the zipper holder 11, and the zipper 12 is fixedly connected to the post 13. During installation, the zipper 12 is engaged with the zipper mounting frame 1 via the post 13, thus connecting the zipper 1 to the zipper mounting frame 1.

[0070] This embodiment provides a highly robust zipper fixing structure for suitcases, further optimizing the zipper fixing method. In particular, it addresses the situation where the fabric edges on both sides of the zipper are fixedly connected to the suitcase shell 6 via two zipper mounting frames 1, ensuring the stability and durability of the overall structure.

[0071] Specifically, the zipper mounting frame 1 consists of two independent frame components, which are respectively fixed to the bottom and lid of the suitcase shell 6. Each frame component has a zipper edge positioning groove 2, and the two side edges 8 of the zipper are respectively embedded in the positioning grooves 2 of the two frame components. To ensure a firm connection, each frame component has a first positioning hole 3 that penetrates the positioning groove 2, which cooperates with the second positioning hole 4 on the zipper edge 8. During installation, rivets 5 are passed through the first positioning hole 3 of the frame, the second positioning hole 4 of the zipper edge 8, and the third positioning hole 7 on the suitcase shell 6 in sequence to achieve a secure riveting fixation of the zipper edge 8, the frame component, and the suitcase shell 6. This structure effectively avoids the risk of the zipper loosening or falling off and enhances the overall connection strength.

[0072] To further improve the fixing effect, during the embedding process of the zipper edge 8, a limiting hole 9 is provided at the bottom of the positioning groove 2 of the zipper mounting frame 1, which cooperates with the positioning post 10 provided on the zipper edge 8. The positioning post 10 can be a fabric reinforcement or a glue stick. By inserting it into the limiting hole 9, it ensures that the zipper edge 8 remains stable during riveting and use, preventing displacement or tearing caused by frequent use. In addition, the cooperation design between the positioning post 10 and the limiting hole 9 evenly distributes the force on the zipper, reduces local wear, and extends the service life of the zipper.

[0073] In this embodiment, the connection method between the zipper mounting frame 1 and the case shell 6 can be adjusted according to aesthetic requirements. In some cases, the case shell 6 and the frame 1 are connected with glue instead of riveting to avoid the impact of exposed rivet heads on the overall aesthetics of the suitcase. However, the zipper 8 is still fixed to the frame 1 with rivets 5 to ensure the zipper 8's sturdiness and durability. This combination of glue and rivets maintains the suitcase's clean appearance while ensuring structural strength.

[0074] Through this optimized design, this embodiment not only solves the problem of loosening or detachment caused by environmental changes in traditional dispensing processes, but also avoids situations where the adhesive process has excessively high requirements for certain materials used in the housing 6. It eliminates traditional sewing and complex dispensing processes, greatly improving production and assembly efficiency and reducing production costs. This structure is suitable for housings 6 made of various materials, such as ABS, PC, and PP.

[0075] like Figure 6 In the shown state, rivet 5 is not riveted to the suitcase shell 6, but in the extended embodiment, Figure 6 The rivets 5 can also be riveted to the suitcase shell 6 to form a more stable connection structure, which are all extended embodiments known to those skilled in the art; and during the connection process, the zipper is not glued to the suitcase shell 6.

[0076] Example 1:

[0077] This embodiment provides a highly robust zipper fixing structure for suitcases, further optimizing the zipper fixing method. In particular, it addresses the situation where the fabric edges on both sides of the zipper are fixedly connected to the suitcase shell 6 via two zipper mounting frames 1, ensuring the stability and durability of the overall structure.

[0078] Specifically, the zipper mounting frame 1 consists of two independent frame components, which are respectively fixed to the bottom and lid of the suitcase shell 6. Each frame component has a zipper edge positioning groove 2, and the two side edges 8 of the zipper are respectively embedded in the positioning grooves 2 of the two frame components. To ensure a firm connection, each frame component has a first positioning hole 3 that penetrates the positioning groove 2, which cooperates with the second positioning hole 4 on the zipper edge 8. During installation, rivets 5 are passed through the first positioning hole 3 of the frame, the second positioning hole 4 of the zipper edge 8, and the third positioning hole 7 on the suitcase shell 6 in sequence to achieve a secure riveting fixation of the zipper edge 8, the frame component, and the suitcase shell 6. This structure effectively avoids the risk of the zipper loosening or falling off and enhances the overall connection strength.

[0079] To further improve the fixing effect, during the embedding process of the zipper edge 8, a limiting hole 9 is provided at the bottom of the positioning groove 2 of the zipper mounting frame 1, which cooperates with the positioning post 10 provided on the zipper edge 8. The positioning post 10 can be a fabric reinforcement or a glue stick. By inserting it into the limiting hole 9, it ensures that the zipper edge 8 remains stable during riveting and use, preventing displacement or tearing caused by frequent use. In addition, the cooperation design between the positioning post 10 and the limiting hole 9 evenly distributes the force on the zipper, reduces local wear, and extends the service life of the zipper.

[0080] In this embodiment, the connection method between the zipper mounting frame 1 and the case shell 6 can be adjusted according to aesthetic requirements. In some cases, the case shell 6 and the frame 1 are connected with glue instead of riveting to avoid the impact of exposed rivet heads on the overall aesthetics of the suitcase. However, the zipper 8 is still fixed to the frame 1 with rivets 5 to ensure the zipper 8's sturdiness and durability. This combination of glue and rivets maintains the suitcase's clean appearance while ensuring structural strength.

[0081] Through this optimized design, this embodiment not only solves the problem of loosening or detachment caused by environmental changes in traditional dispensing processes, but also avoids situations where the adhesive process has excessively high requirements for certain materials used in the casing 6. The elimination of traditional sewing and complex dispensing processes significantly improves production and assembly efficiency and reduces production costs. This structure is suitable for casings 6 made of various materials, such as ABS, PC, and PP, further enhancing the product's adaptability and market competitiveness.

[0082] Example 2:

[0083] In everyday luggage use, zippers, as an important sealing device, directly affect the convenience and structural sturdiness of the luggage. In existing technologies, zippers are typically fixed by sewing them onto the outer shell or by gluing the frame containing the zipper to the luggage shell 6. However, these methods suffer from complex manufacturing processes, insufficient environmental friendliness, and poor durability. To address these issues, this embodiment provides a method for fixing the zipper 14 of a luggage based on physical riveting and a limiting structure.

[0084] In this embodiment, firstly, the zipper mounting frame 1 is fixed to the suitcase shell via a pre-set connecting structure. One side of the zipper mounting frame 1 is provided with a zipper edge positioning groove 2 for accommodating the zipper edge. This groove allows for precise positioning of the zipper edge and ensures its fit with the suitcase shell 6. Several first positioning holes 3 are evenly distributed on the portion of the zipper edge opposite the zipper edge positioning groove 2, and the zipper mounting frame 1 also has corresponding second positioning holes 4. During installation, the zipper edge is riveted to the zipper mounting frame 1 by aligning the positioning holes on the zipper edge with the positioning holes on the zipper mounting frame 1 and using rivets 5 passing through these positioning holes. This physical riveting method replaces the traditional adhesive bonding method, avoiding the problem of weak fixation caused by glue aging, and eliminating complex processes such as applying glue, heating, and cooling, greatly improving production efficiency.

[0085] To further enhance the stability of the zipper edge, a limiting hole 9 is provided at the bottom of the zipper edge positioning groove 2 in this embodiment, and a positioning post 10 that cooperates with the limiting hole 9 is provided on the zipper edge. The positioning post 10 can be made of materials such as fabric reinforcement or glue sticks. By inserting it into the limiting hole 9, the zipper edge portion extends into the limiting hole 9, thereby securely embedding itself in the zipper edge positioning groove 2. This design not only ensures the stability of the zipper edge during riveting, preventing displacement or tearing, but also further improves the firmness of the zipper fixation through the cooperation of the limiting structure.

[0086] This embodiment is specifically applied in high-intensity usage scenarios, such as the frequent opening and closing of suitcases over extended periods. With traditional adhesive application processes, adhesive aging and environmental changes can cause the zipper fabric edge to loosen or detach, especially under extreme temperature conditions (such as high or low temperatures), where adhesive performance significantly degrades, resulting in unstable fixing. However, the dual fixing method of riveting and limiting used in this embodiment is unaffected by temperature changes, ensuring the long-term stability of the zipper. Furthermore, the application of fabric reinforcement or adhesive sticks as positioning posts 10 not only simplifies the installation process but also effectively prevents wear on the zipper fabric edge during high-frequency use, extending the zipper's lifespan.

[0087] Through this innovative structural design, the luggage zipper fixing solution provided in this embodiment solves the problems of insufficient environmental friendliness, complex manufacturing process, and poor durability in existing technologies. It significantly improves the connection strength between the zipper and the suitcase shell 6, extending the lifespan of the luggage. At the same time, this design avoids harmful substances generated by the use of adhesives, meeting today's market requirements for environmentally friendly products. The overall structure is not only more robust and durable but also maintains the aesthetic appeal and consistency of the luggage's appearance.

[0088] Example 3:

[0089] This embodiment provides a high-strength zipper fixing structure and its installation method for suitcases, aiming to improve the connection between the zipper and the suitcase shell, while simplifying the manufacturing process and improving the product's durability.

[0090] In this embodiment, a zipper mounting frame 1 is first provided, which is used to fix the zipper mounting frame 1 to the suitcase shell 6. One side of the zipper mounting frame 1 is designed with a zipper edge positioning groove 2 for accommodating the zipper edge. The width and depth of the groove match the thickness of the zipper edge to ensure that the zipper edge can be securely embedded therein. To further enhance the fixing effect of the zipper edge, several first positioning holes 3 are evenly distributed on the zipper mounting frame 1, penetrating the zipper edge positioning groove 2. Simultaneously, second positioning holes 4 corresponding to these first positioning holes 3 are also evenly provided on the zipper edge. During installation, after the zipper edge is embedded in the zipper edge positioning groove 2, rivets 5 pass through these first positioning holes 3 and second positioning holes 4, firmly riveting the zipper mounting frame 1 to the zipper edge.

[0091] In a further improvement of this embodiment, a third positioning hole 7 matching the first positioning hole 3 and the second positioning hole 4 is also provided on the suitcase shell 6. During installation, the rivet 5 not only passes through the zipper mounting frame 1 and the zipper edge, but also through the third positioning hole 7 of the suitcase shell 6, thereby achieving a firm riveting connection between the zipper mounting frame 1, the zipper edge, and the suitcase shell 6. This multi-riveting structure greatly improves the overall fixing firmness of the zipper, ensuring that it will not loosen or fall off during long-term use, and adapting to the high-intensity opening and closing environment of suitcases.

[0092] Furthermore, to further improve the stability of the zipper edge, a limiting hole 9 is provided at the bottom of the groove of the zipper mounting frame 1, which cooperates with the positioning post 10 provided on the zipper edge. The positioning post 10 can be in the form of a fabric reinforcement or a glue stick, and its end can be designed as round or rectangular as required. During installation, the positioning post 10 on the zipper edge is inserted into the limiting hole 9, so that the zipper edge part protrudes into the limiting hole 9 and is firmly embedded in the groove, further enhancing the fixing effect of the zipper edge. This limiting design can effectively prevent the zipper edge from shifting or tearing during use.

[0093] In practical applications, this design of positioning pins 10 and limiting holes 9 not only increases the fixing strength of the zipper edge but also simplifies the installation process. By inserting the fabric reinforcement or glue stick as positioning pins 10 into the limiting holes 9, it can be ensured that the zipper edge smoothly embeds into the zipper edge positioning groove 2, thereby reducing the requirements for assembly precision and lowering the difficulty of manual adjustment during production. In addition, the dual physical fixing of positioning pins 10 and limiting holes 9 can evenly distribute the force on the zipper in situations of frequent use, avoiding localized pulling and wear, and significantly extending the service life of the suitcase.

[0094] The entire zipper fixing structure not only provides high-strength fixation through rivets 5, but also further enhances the stability of the fixation through a limiting structure, solving the problems of insufficient environmental friendliness, complex manufacturing process, and poor durability of existing adhesive fixing methods. This highly robust fixing structure significantly improves both the appearance and lifespan of the suitcase, making it particularly suitable for high-frequency use scenarios.

[0095] The specific installation steps in this embodiment are as follows:

[0096] 1. Connect the zipper mounting frame 1 to the suitcase shell 6, or prepare the zipper mounting frame 1 in advance to connect with the suitcase shell 6.

[0097] 2. A zipper edge positioning groove 2 is provided on one side of the zipper mounting frame 1 to accommodate the zipper edge.

[0098] 3. Form corresponding positioning holes on the zipper edge and the corresponding part of the zipper mounting frame 1 to align the positioning holes.

[0099] 4. The zipper mounting frame 1 and the zipper edge are riveted and fixed by passing the rivet 5 through the first positioning hole 3 of the zipper mounting frame 1 and the second positioning hole 4 of the zipper edge.

[0100] 5. If necessary, a third positioning hole 7 can be provided on the suitcase shell 6 so that the rivet 5 passes through the zipper mounting frame 1, the zipper edge and the third positioning hole 7 of the suitcase shell 6 in sequence, thereby fixing the three together to form a more stable connection.

[0101] 6. Set a limiting hole 9 at the bottom of the groove of the zipper mounting frame 1, and form a corresponding positioning post 10 on the zipper fabric edge. Insert the positioning post 10 into the limiting hole 9, so that the zipper fabric edge protrudes into the limiting hole 9, ensuring that it is firmly embedded in the zipper fabric edge positioning groove 2.

[0102] The high-strength zipper fixing structure in this embodiment not only improves the connection strength between the zipper and the suitcase shell, but also simplifies the production process and enhances the product's environmental friendliness and durability.
