Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a luggage with a convenient installation structure. Background Technology

[0002] Luggage is a common tool for travel. Luggage includes zippered and snap-lock types for easy opening and closing. Common zippered luggage typically involves attaching a soft rubber material to the outside of the case and then sewing the zipper on. This often presents the following problems: First, under prolonged tension or pressure from the case, the zipper can easily detach from the seam or adhesive joint. Second, the case joints often use thin sheets or single-layer structures, lacking effective abutment or sealing, allowing dust and rainwater to easily enter the case. Third, the zipper connection requires sewing or multi-layer bonding processes for fixation, resulting in poor production consistency and low efficiency. The internal structure often requires separate bonding or sewing, leading to high rework rates. Therefore, a new zipper installation structure is needed that is structurally stable, has good sealing properties, and is suitable for mass production to improve the strength, reliability, and production efficiency of luggage.

Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, all directional indications (such as up, down, left, right, front, back, bottom, etc.) in this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, descriptions involving "first," "second," etc., in this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0036] like Figure 1-4 As shown, the bag with a convenient installation structure provided in this embodiment includes a first box body 11 and a second box body 12 arranged opposite to each other. The sides of the first box body 11 and the second box body 12 are provided with bending connecting portions, allowing the first box body 11 and the second box body 12 to be bent and connected, forming a complete storage space when the bag is closed. The bending connecting portions are preferably located in the middle of the sides of the first box body 11 and the second box body 12.

[0037] A first retaining ring 21 is provided on the edge of the first housing 11, and a second retaining ring 22 is provided on the edge of the second housing 12. In this embodiment, the first retaining ring 21 is provided with a first slot 13 for engaging with the edge of the first housing 11, and the second retaining ring 22 is provided with a second slot 14 for engaging with the edge of the second housing 12. After engaging, the retaining rings can be fixedly connected to the housing edges in various ways. For example, the retaining rings can be firmly bonded to the housing edges with adhesive, or connected with mechanical fasteners. In this embodiment, the retaining rings are integrally connected to the housing edges by heat pressing. These connection methods are designed to ensure the bonding strength between the retaining rings and the housing edges, providing a stable foundation for the installation of subsequent components.

[0038] The first fixing ring 21 has a first groove 23, and a first connecting ring 31 is fixed in the first groove 23; the second fixing ring 22 has a second groove 24, and a second connecting ring 32 is fixed in the second groove 24. Specifically, the bottom of the first connecting ring 31 and the bottom of the first groove 23, as well as the bottom of the second connecting ring 32 and the bottom of the second groove 24, are bonded together with adhesive, and both the first connecting ring 31 and the second connecting ring 32 are provided with an access portion.

[0039] A first engaging groove 41 for engaging the zipper link is formed between the first connecting ring 31 and the side wall of the first groove 23, and a second engaging groove 42 for engaging the inside of the box is formed between the second connecting ring 32 and the side wall of the second groove 24, and a fourth engaging groove 44 for engaging the zipper link is formed between the second connecting ring 32 and the side wall of the second groove 24.

[0040] The first connecting ring 31 has a first extension 33, and the second connecting ring 32 has a second extension 34. When the first housing 11 and the second housing 12 are closed, the first extension 33 and the second extension 34 abut against each other to form a stable closed structure. The first extension 33 and the second extension 34 can be designed to have flat contact surfaces, which fit together when the housings are closed. Alternatively, they can be designed to have complementary protrusions and recesses, forming a tighter fit when abutting.

[0041] The bag with a convenient installation structure provided in this embodiment has a limiting flange 5 on both the first connecting ring 31 and the second connecting ring 32. A first locking groove 41 and a second locking groove 42 are formed sequentially between the limiting flange 5 and the side wall of the first groove 23; a third locking groove 43 and a fourth locking groove 44 are formed sequentially between the limiting flange 5 and the side wall of the second groove 24. The first locking groove 41 and the third locking groove 43 are side-entry locking grooves. To improve bonding stability, the bottom of the first connecting ring 31 and the second connecting ring 32 are provided with recessed portions, and the bottom of the first groove 23 and the second groove 24 are provided with protrusions corresponding to the recessed portions. This increases the contact area between the connecting ring and the groove, thereby increasing the bonding stability. Overall, the fixing ring has a "T" shaped structure. In addition, the protrusions and recesses also play a positioning role when bonding the fixing ring and the groove, preventing the extension from failing to properly engage due to errors, thus affecting the sealing performance of the bag.

[0042] The zipper used in this embodiment includes chain teeth, chain strap, and locking teeth, with the chain teeth and locking teeth connected to both ends of the chain strap. After the limiting flange 5 at the end furthest from the bottom of the groove forms a locking groove with the side wall of the groove, a gap is left for the chain strap to pass through. In use, the locking teeth at both ends of the zipper are respectively engaged with the first locking groove 41 and the third locking groove 43 through the access part, forming a zipper structure that allows the case to close along the path of the first locking groove 41 and the third locking groove 43. Similarly, the locking tooth structure inside the case is engaged with the second locking groove 42 and the fourth locking groove 44.

[0043] The bag with a convenient installation structure provided in this embodiment has a first connecting ring 31 and a second connecting ring 32 that are integrally injection molded. During production, the structure and position of the limiting flange 5 can be adaptively adjusted according to the size or shape of the matching zipper and inner teeth to achieve a stable connection.

[0044] The bag with a convenient installation structure provided in this embodiment, through the setting of a fixing ring, a connecting ring, and a snap-fit ​​groove, allows the zipper to be reliably snapped into the inner lining of the bag, resulting in a robust structure, good sealing, and easy installation. First, both the zipper and the inner lining can be fixed via the snap-fit ​​groove, ensuring the stability of the bag while enabling quick installation. Second, the connecting ring is integrally injection molded and bonded to the fixing ring. The bottom of the connecting ring has a recessed portion, and the fixing ring has a corresponding protrusion, which allows for initial positioning during bonding and increases the bonding area, making installation convenient and highly stable. Third, the connecting ring has a limiting flange 5 and an extension. The limiting flange 5 and the fixing ring together define the snap-fit ​​groove for snapping the zipper and the inner lining, and the extension abuts when the bag is closed, improving the airtightness and stability of the bag structure. Finally, the fixing ring uses... The injection molding process, which involves directly bonding the fixing ring and connecting ring to form a snap-fit ​​groove, eliminates the need for the traditional process of extruding and then bending the fixing and connecting rings. Compared to traditional injection molding, where zippers or linings can only be bonded through snap-fit ​​grooves, the snap-fit ​​groove formed by the special structure of the fixing and connecting rings in this invention avoids the need for multiple separate bonding processes of the zipper or lining. The snap-fit ​​groove can be formed by bonding the connecting ring only once, simplifying the process and improving production efficiency. The zipper and lining are also easy to install and easy to repair and replace.

[0045] The specific embodiments of this utility model have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
