Description

Technical Field

[0001] The utility model relates to the technical field of fixing technology for plastic frames, zippers and cases of suitcases, and particularly relates to a fixing structure and method for a suitcase zipper and case with high firmness. Background Art

[0002] Suitcases are widely used in daily life and travel, especially suitcases with zippers. The fixing structure of the zipper is directly related to the convenience of use and the durability of the product. In the prior art, the fixing of suitcase zippers usually adopts the methods of sewing or gluing, that is, the frame with a zippered cloth edge is fixed to the case of the suitcase by sewing on the case or applying glue. Although this method is simple to operate and can ensure the fixing effect of the zipper in the initial stage, with the improvement of environmental protection requirements, the improvement of production efficiency and the requirements for product durability, the gluing method gradually exposes its deficiencies, especially the limitations in the design of the zipper installation frame of the suitcase:

[0003] 1. Insufficient durability and reliability: The gluing method has certain limitations in the zipper fixing structure, especially in the part of the zipper installation frame. As the use time increases, the bonding strength of the glue is easily affected by external environments such as temperature and humidity, which may cause the zipper cloth edge to loosen or even fall off. In addition, the problem of glue aging is also a key factor. After long-term use, the glue will gradually lose its viscosity or even crack, seriously affecting the firmness of the zipper and the service life of the suitcase.

[0004] 2. Lack of environmental protection: The glue used in the gluing process usually contains harmful chemical substances such as formaldehyde. Even after being cured by high-temperature heating, these harmful components may still remain in the finished product and are difficult to volatilize completely. This not only pollutes the environment, but also during use, especially in extreme environments such as high temperature and high humidity, these chemical substances may be released, affecting the health of users. With the increasing market demand for environmentally friendly products, the traditional gluing process obviously cannot meet the requirements of green environmental protection standards.

[0005] 3. Complex production process and low efficiency: The gluing fixing process of the zipper involves multiple complex steps, including glue application, heating, curing and cooling processes. First of all, the glue application process needs to accurately control the amount of glue to avoid excess glue affecting the appearance of the product; secondly, the glue curing process takes a long time, increasing the production cycle; finally, the cooling step further delays the production progress. The complexity of these steps not only increases the production cost, but also reduces the production efficiency, making it difficult to meet the requirements of the suitcase industry for high-efficiency production.

[0006] Therefore, how to provide a fixing structure for a suitcase zipper with high environmental protection, simplified process flow and able to ensure the firm fixing of the zipper has become the technical problem to be solved by the present utility model. Content of the Utility Model

[0015] As a further solution of the present utility model, the limiting hole is located at the bottom of the zipper cloth edge positioning groove.

[0016] As a further solution of the present utility model, the positioning post is a cloth tendon or a rubber rod.

[0017] As a further solution of the present utility model, the end cross-sectional shape of the rubber rod is circular or rectangular.

[0018] As a further solution of the present utility model, the zipper cloth edge positioning groove and the limiting hole respectively penetrate the front end and / or the rear end of the zipper installation frame.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. By riveting and fixing the zipper installation frame and the zipper cloth edge, a more stable and durable fixing method is provided.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0038] Please refer to Figure 1 —9. In the embodiment of the present utility model, a high-strength luggage zipper fixing structure includes a zipper installation frame body 1, a zipper cloth edge positioning groove 2, a first positioning hole 3, a second positioning hole 4 and a rivet 5;

[0039] The zipper installation frame body 1 is used for fixedly connecting with the box shell 6 of the luggage; a zipper cloth edge positioning groove 2 is arranged on one side of the zipper installation frame body 1, and the first positioning holes 3 penetrating through the zipper cloth edge positioning groove 2 are evenly distributed on the zipper installation frame body 1;

[0040] The second positioning holes 4 that match the first positioning holes 3 are evenly arranged on the zipper cloth edge 8 that matches the zipper cloth edge positioning groove 2; the rivets 5 pass through the first positioning holes 3 and the second positioning holes 4 to rivet and connect the zipper installation frame body 1 and the zipper cloth edge.

[0041] The third positioning holes 7 are arranged on the case shell 6 of the luggage, and the rivets 5 pass through the first positioning holes 3, the second positioning holes 4 and the third positioning holes 7 to rivet and connect the zipper installation frame body 1, the zipper cloth edge and the case shell 6 of the luggage to each other. A limiting hole 9 communicating with the zipper cloth edge positioning groove 2 is arranged on the zipper installation frame body 1, and the positioning post 10 is in limiting cooperation with the limiting hole 9. One side of the zipper cloth edge extends into the limiting hole 9 and is fixedly connected to the side part of the positioning post 10.

[0042] The limiting hole 9 is located at the bottom of the zipper cloth edge positioning groove 2. The positioning post 10 is a cloth rib or a rubber rod. The end cross-sectional shape of the rubber rod is circular or rectangular. The zipper cloth edge positioning groove 2 and the limiting hole 9 respectively penetrate through the front end and / or the rear end of the zipper installation frame body 1; as Figure 9 shown, in an extended embodiment of the present utility model, at a position inside the zipper installation frame body 1, an explosion-proof limiting protrusion 15 can be arranged, so as to facilitate explosion-proof limiting support under the flexible zipper through the rigid explosion-proof limiting protrusion 15, which all belong to the extended implementation manners known to those of ordinary skill in the art.

[0043] The present utility model discloses a high-firmness luggage zipper fixing structure, and finally forms a zipper installation frame body 1 composed of two components. The structure includes two frame bodies respectively fixedly connected to the case shell 6 of the luggage, and each frame body is used to fix one side edge of the zipper. Through reasonable design and connection methods, the firm fixation of the zipper and the case shell 6 is realized.

[0044] Specifically, the zipper installation frame body 1 is composed of two independent frame body components, which are respectively installed on both sides of the case shell 6 at the bottom and the cover of the luggage. Each frame body component is provided with a zipper cloth edge positioning groove 2. The two side cloth edges of the zipper are respectively embedded in the positioning grooves of each frame body component and are fixed through positioning holes and rivets 5.

This structure not only improves the assembly efficiency but also reduces the production cost by eliminating the traditional sewing and gluing processes, simplifies the assembly process, and at the same time ensures a strong connection between the zipper structure and the case body and the reliability for long-term use.

[0047] A method for fixing a suitcase zipper with high firmness, comprising:

[0048] Connect the zipper installation frame 1 to the suitcase shell 6 body, or prepare in advance the zipper installation frame 1 to be connected to the suitcase shell 6 body;

[0049] Provide a zipper edge positioning groove 2 for accommodating the zipper edge on one side of the zipper installation frame 1; form corresponding positioning holes in the corresponding parts of the zipper edge and the zipper installation frame 1 for easy alignment; pass a rivet 5 through the positioning hole of the zipper installation frame 1 and the positioning hole of the zipper edge to rivet and fix the zipper installation frame 1 and the zipper edge.

[0050] Fix the suitcase shell 6 body to the zipper installation frame 1 or the zipper edge for overall fixation.

[0051] It further includes the following steps:

[0052] Provide a cloth rib or a glue stick as a positioning post 10; set a limit hole 9 at the bottom of the groove of the zipper installation frame 1 and form a corresponding positioning post 10 on the zipper edge; insert the positioning post 10 into the limit hole 9 so that a part of the zipper edge extends into the limit hole 9 to firmly embed the zipper edge into the zipper edge positioning groove 2.

[0053] It further includes the following steps:

[0054] Set a third positioning hole 7 on the suitcase shell 6 body;

[0055] Pass a rivet 5 through the first positioning hole 3 of the zipper installation frame 1, the second positioning hole 4 of the zipper edge, and the third positioning hole 7 of the suitcase shell 6 body in sequence to fix the zipper installation frame 1, the zipper edge, and the suitcase shell 6 body together.

[0056] In an extended embodiment, a lining zipper catch 11 is provided on the zipper installation frame 1. The lining zipper catch 11 is used to support and fix the lining zipper 12 inside the suitcase. One side of the lining zipper 12 is fixedly connected to a column 13 that cooperates with the lining zipper catch 11, and the lining zipper 12 is fixedly connected to the column 13. During installation, the lining zipper 12 is snapped onto the zipper installation frame 1 through the column 13 to achieve the connection between the lining zipper and the zipper installation frame 1.

[0057] This embodiment provides a high-strength zipper fixing structure for a suitcase, further optimizing the zipper fixing method. Especially for the case where the two side edges of the zipper are respectively fixedly connected to the suitcase shell 6 through two zipper mounting frames 1, the stability and durability of the overall structure are ensured.

[0058] Specifically, the zipper mounting frame 1 is composed of two independent frame components, which are respectively fixed on the suitcase shells 6 at the bottom and the lid of the suitcase. Each frame component is provided with 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, a first positioning hole 3 penetrating through the positioning groove 2 is evenly arranged on each frame component, which cooperates with the second positioning hole 4 on the zipper edge 8. During installation, the rivet 5 sequentially passes 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, realizing the firm riveting and fixing 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.

[0059] 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 cloth rib 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 matching design of the positioning post 10 and the limiting hole 9 evenly disperses the stress of the zipper, reduces local wear, and extends the service life of the zipper.

[0060] In this embodiment, the connection method between the zipper mounting frame 1 and the suitcase shell 6 can be adjusted according to the appearance requirements. In some cases, the suitcase shell 6 and the frame 1 are connected by glue instead of riveting, avoiding the influence of the exposed rivet heads on the overall aesthetics of the suitcase. However, the zipper 8 and the frame 1 are still fixed by the rivet 5 to ensure the firmness and durability of the zipper 8. This combination of glue and rivet not only keeps the appearance of the suitcase clean but also ensures the structural strength.

[0061] Through this optimized design, this embodiment not only solves the problem of loosening or falling off caused by environmental changes in the traditional glue-pointing process but also avoids the situation where the glue process has too high requirements for the suitcase shell 6 of certain materials. Canceling the traditional sewing process and the complex glue-pointing process greatly improves the production and assembly efficiency and reduces the production cost. This structure is applicable to suitcase shells 6 of various materials, such as ABS, PC, PP, etc.

[0062] As Figure 6 shown in the state, the rivet 5 is not riveted to the suitcase shell 6 of the suitcase, but in an extended embodiment, Figure 6The rivet 5 in it can also be riveted to the case 6 of the luggage to form a more stable connection structure, which all belong to the extended implementation manners known to those of ordinary skill in the art; and during the connection process, the zipper is not adhesively bonded to the case 6 with glue.

[0063] Embodiment 1:

[0064] This embodiment provides a high-strength zipper fixing structure for a suitcase, which further optimizes the fixing method of the zipper. Especially for the case where the two side edges of the zipper are respectively fixedly connected to the case 6 through two zipper mounting frames 1, the stability and durability of the overall structure are ensured.

[0065] Specifically, the zipper mounting frame 1 is composed of two independent frame components, which are respectively fixed on the cases 6 of the bottom and the lid of the suitcase. Each frame component is provided with 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, a first positioning hole 3 penetrating through the positioning groove 2 is uniformly arranged on each frame component, which cooperates with the second positioning hole 4 on the zipper edge 8. During installation, the rivet 5 sequentially passes 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 case 6 to achieve the firm riveting and fixing of the zipper edge 8, the frame component, and the case 6. This structure effectively avoids the risk of the zipper loosening or falling off and enhances the overall connection strength.

[0066] 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 cloth tendon 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 matching design of 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.

[0067] In this embodiment, the connection method between the zipper mounting frame 1 and the case 6 can be adjusted according to the appearance requirements. In some cases, the case 6 and the frame 1 are connected by glue instead of riveting, avoiding the influence of the exposed rivet head on the overall aesthetics of the suitcase. However, the zipper 8 and the frame 1 are still fixed by the rivet 5 to ensure the firmness and durability of the zipper 8. This combination of glue and rivet not only keeps the appearance of the suitcase clean but also ensures the strength of the structure.

[0068] Through this optimized design, this embodiment not only solves the problem of loosening or falling off caused by environmental changes in the traditional dispensing process, but also avoids the situation where the glue process has overly high requirements for the housing 6 of certain materials. The traditional sewing process and complex dispensing process are cancelled, greatly improving the production and assembly efficiency and reducing the production cost. This structure is applicable to the housings 6 of various materials, such as ABS, PC, PP, etc., further enhancing the adaptability and market competitiveness of the product.

[0069] Embodiment 2:

[0070] In the daily use of a luggage case, as an important closing device, the zipper directly affects the usability and structural firmness of the luggage case. In the prior art, the zipper is usually fixed by sewing on the outer shell or by bonding the frame containing the zipper to the luggage case body 6 by means of dispensing, but this method has problems such as complex production process, insufficient environmental protection and poor durability. To solve this series of problems, this embodiment provides a fixing method for the zipper 14 of a luggage case based on physical riveting and a limiting structure.

[0071] In this embodiment, first, the zipper mounting frame body 1 is fixed to the housing of the luggage case through a preset connection structure. On one side of the zipper mounting frame body 1, there is a zipper edge positioning groove 2 for accommodating the zipper edge, and this groove can accurately position the zipper edge and ensure its fit with the housing 6. On the part of the zipper edge opposite to the zipper edge positioning groove 2, a number of first positioning holes 3 are evenly distributed, and corresponding second positioning holes 4 are also provided on the zipper mounting frame body 1. During the installation process, by aligning the positioning holes on the zipper edge with the positioning holes on the zipper mounting frame body 1 and using rivets 5 to pass through these positioning holes, the zipper edge and the zipper mounting frame body 1 are riveted and fixed. This physical riveting method replaces the traditional dispensing bonding method, avoids the problem of insecure fixation caused by glue aging, and at the same time omits complex process steps such as glue application, heating, and cooling, greatly improving the production efficiency.

[0072] To further enhance the fixing stability of the zipper edge, in this embodiment, a limiting hole 9 is provided at the bottom of the zipper edge positioning groove 2, and a positioning post 10 matching the limiting hole 9 is provided on the zipper edge. The positioning post 10 can be made of materials such as cloth ribs or glue rods, and by inserting it into the limiting hole 9, part of the zipper edge can be inserted into the limiting hole 9, and then firmly embedded in the zipper edge positioning groove 2. This design can not only ensure the stability of the zipper edge during the riveting process, prevent displacement or tearing, but also further improve the fixing firmness of the zipper through the cooperation of the limiting structure.

[0073] The specific application scenario of this embodiment is a high-intensity usage occasion, such as the usage environment of a suitcase that is frequently opened and closed for a long time. Under the traditional dispensing process, the aging of the glue and environmental changes may cause the loosening or detachment of the zipper cloth edge. Especially under extreme temperature conditions (such as high or low temperature environments), the performance of the glue will drop significantly, and the fixing effect is unstable. However, the double fixing method of riveting and limiting adopted in this embodiment is not affected by temperature changes, ensuring the long-term stability of the zipper. In addition, the application of the cloth rib or the glue stick as the positioning post 10 not only simplifies the installation process but also effectively prevents the wear of the zipper cloth edge during high-frequency use, extending the service life of the zipper.

[0074] Through this innovative structural design, the suitcase zipper fixing solution provided by this embodiment solves the problems existing in the prior art, such as insufficient environmental protection, complex production process, and poor durability, significantly improving the connection strength between the zipper and the case 6 of the suitcase and extending the service life of the suitcase. At the same time, this design avoids the harmful substances generated by the use of glue, meeting the requirements of today's market for environmentally friendly products. The overall structure is not only more durable but also maintains the beauty and consistency of the appearance of the suitcase.

[0075] Embodiment 3:

[0076] This embodiment provides a high-firmness zipper fixing structure for a suitcase and its installation method, aiming to improve the connection firmness between the zipper and the suitcase case 6, while simplifying the production process and enhancing the durability of the product.

[0077] In this embodiment, first, a zipper installation frame 1 is provided, which is used for fixedly connecting with the case 6 of the suitcase. One side of the zipper installation frame 1 is designed with a zipper cloth edge positioning groove 2 for accommodating the zipper cloth edge. The width and depth of this groove match the thickness of the zipper cloth edge to ensure that the zipper cloth edge can be firmly embedded therein. To further strengthen the fixing effect of the zipper cloth edge, a number of first positioning holes 3 are evenly distributed on the zipper installation frame 1, penetrating through the zipper cloth edge positioning groove 2. At the same time, corresponding second positioning holes 4 are also evenly arranged on the zipper cloth edge. During the installation process, after the zipper cloth edge is embedded in the zipper cloth edge positioning groove 2, the zipper installation frame 1 and the zipper cloth edge are firmly riveted together by passing rivets 5 through these first positioning holes 3 and second positioning holes 4.

[0078] In a further improvement of this embodiment, a third positioning hole 7 matching the above-mentioned first positioning hole 3 and second positioning hole 4 is also provided on the case shell 6 of the luggage. During the installation process, the rivet 5 not only passes through the zipper mounting frame 1 and the zipper cloth edge, but also passes through the third positioning hole 7 of the luggage case shell 6, thereby realizing a firm riveted connection among the zipper mounting frame 1, the zipper cloth edge and the luggage case shell 6. This multiple-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 use environment of high-intensity opening and closing of the luggage.

[0079] In addition, to further improve the stability of the zipper cloth 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 cloth edge. The positioning post 10 can be in the form of a cloth rib or a glue stick, and its end can be designed as a circle or a rectangle according to requirements. During installation, the positioning post 10 on the zipper cloth edge is inserted into the limiting hole 9, so that part of the zipper cloth edge extends into the limiting hole 9 and is firmly embedded in the groove, further enhancing the fixing effect of the zipper cloth edge. This limiting design can effectively prevent the zipper cloth edge from shifting or tearing during use.

[0080] In practical applications, the design of using this positioning post 10 and limiting hole 9 not only increases the fixing strength of the zipper cloth edge, but also simplifies the installation process. By inserting the cloth rib or glue stick as the positioning post 10 into the limiting hole 9, it can ensure that the zipper cloth edge is smoothly embedded in the zipper cloth edge positioning groove 2, thus reducing the requirement for assembly accuracy and the difficulty of manual debugging in production. In addition, the dual physical fixation of the positioning post 10 and the limiting hole 9 can evenly disperse the force of the zipper in frequently used occasions, avoid local pulling and wear, and greatly extend the service life of the luggage.

[0081] The entire zipper fixing structure not only provides high-strength fixation through the rivet 5, but also further enhances the stability of the fixation through the limiting structure, solving the problems of insufficient environmental protection, complex production process and poor durability of the existing glue-point fixing method. Through this high-firmness fixing structure, the appearance aesthetics and service life of the luggage have been significantly improved, especially suitable for the luggage scenario with high-frequency use.

[0082] The specific installation steps of this embodiment are as follows:

[0083] 1. Connect the zipper mounting frame 1 with the luggage case shell 6, or prepare in advance the zipper mounting frame 1 connected with the luggage case shell 6.

[0084] 2. Provide a zipper cloth edge positioning groove 2 for accommodating the zipper cloth edge on one side of the zipper mounting frame 1.

[0085] 3. Form corresponding positioning holes at the corresponding parts of the zipper cloth edge and the zipper mounting frame 1, and align the positioning holes.

[0086] 4. Pass the rivet 5 through the first positioning hole 3 of the zipper mounting frame 1 and the second positioning hole 4 of the zipper cloth edge to complete the riveting and fixing of the zipper mounting frame 1 and the zipper cloth edge.

[0087] 5. If necessary, a third positioning hole 7 can be provided on the trunk shell 6 body, so that the rivet 5 passes through the zipper mounting frame 1, the zipper cloth edge and the third positioning hole 7 of the trunk shell 6 body in sequence, thereby fixing the three together to form a more stable connection.

[0088] 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 cloth edge. Insert the positioning post 10 into the limiting hole 9, so that the zipper cloth edge extends into the limiting hole 9 to ensure its stable embedding in the positioning groove 2 of the zipper cloth edge.

[0089] Through the high-firmness zipper fixing structure of this embodiment, not only the connection strength between the zipper and the trunk shell 6 body is improved, but also the production process is simplified, and the environmental protection and durability of the product are improved.
