Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] This utility model provides a bag / suitcase including an anti-theft zipper. The anti-theft zipper prevents unauthorized opening of the bag, ensuring the security and privacy of the contents. The anti-theft zipper includes a zipper body, two bases, and interlocking pull tabs. Both bases are slidably mounted on the zipper body to allow the zipper body to open and close.

[0021] Please see Figure 1 The interlocking pull tab includes two pull tabs 10a and 10b, which are respectively connected to two bases to enable relative movement between the two bases. When the two bases are close to each other, the two pull tabs 10a and 10b are interlocked to lock the zipper body in the closed state. After the two pull tabs 10a and 10b are unlocked, the two bases can be moved away from each other, thereby opening the zipper. The anti-theft function is achieved by using the cooperation structure of the two pull tabs.

[0022] The two pull tabs 10a and 10b have the same structure. We will introduce the structure of one of the pull tabs, 10a.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, pull tab 10a includes a pull rod 11a and a mating ring 12a. One end of the pull rod 11a is connected to the base, and the other end is connected to the mating ring 12a. Correspondingly, pull tab 10b includes a pull rod 11b and a mating ring 12b. The mating rings 12a and 12b of the two pull tabs 10a and 10b can be interlocked, and the user can use the pull rods 11a and 11b to interlock or unlock the mating rings 12a and 12b.

[0024] The mating ring 12a is bent into an open ring shape. One end of the mating ring 12a is fixedly connected to the other end of the pull rod 11a, and the other end is the mating end 120a, forming a gap 100a between it and the pull rod 11a. The cross-sectional diameter of the mating ring 12a is larger than the size of the gap 100a, and the outer diameter of the pull rod 11a is larger than the size of the gap 100a. Since both the cross-sectional diameter of the mating ring 12a and the outer diameter of the pull rod 11a are larger than the size of the gap 100a, neither the mating ring 12a nor the pull rod 11a can directly pass through the gap 100b of the other pull tab 10b into or out of the other mating ring 12b.

[0025] When the mating end 120a of one pull tab 10a is located at the gap 100b of another pull tab 10b, the mating end 120a of one pull tab 10a can pass through the mating ring 12b of the other pull tab 10b, so that the two mating rings 12a and 12b are interlocked. Utilizing the gap between the two pull tabs 10a and 10b, the mating end 120a can be inserted into the mating ring 12b of the other pull tab 10b at the gap 100b, achieving interlocking of the two pull tabs 10a and 10b; conversely, it can be unlocked. This structure requires a certain level of skill and familiarity with the structure of the pull tabs to unlock. The mating ring 12a and the pull rod 11a are both relatively large and cannot be directly opened through the gap 100b of the other pull tab 10b, thus preventing unauthorized opening and providing a certain degree of anti-theft effect in terms of physical structure. This structure is simple, low-cost, and easy to use.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, two baffles 121a are provided at the docking end 120a. The two baffles 121a are coaxially arranged and extend along the central axis of the docking ring 12a, so that the two baffles 121a are respectively placed on both sides of the docking rings 12a and 12b. Each baffle 121a has an axially fixed end 1211a and a free end 1212a. The fixed end 1211a is fixedly connected to the docking end 120a, and the distance between the two free ends 1212a is greater than the inner diameter of the docking ring 12a.

[0027] When the two pull tabs 10a and 10b are interlocked, the two pull tabs 10a and 10b are in a separated state, such as Figure 5 As shown, the two pull rods 11a and 11b are arranged crosswise, and the stop posts 121a and 121b of the two pull tabs 10a and 10b are also arranged crosswise, with one stop post 121a located at the gap 100b of the other pull tab 10b. Figure 6 As shown, the stop post 121a is moved toward the inside of the other docking ring 12b, so that it passes through the other docking ring 12b; as Figure 7 As shown, another stop post 121a is then passed through the mating ring 12b from the gap 100b; as Figure 8 , Figure 9 As shown, this allows both stop pins 121a to pass through the docking ring 12b of the other pull tab 10b, thus completing the interlocking between the two pull tabs 10a and 10b.

[0028] Conversely, when unlocking the two pull tabs 10a and 10b, the gaps 100a and 100b between the two pull tabs 10a and 10b are brought closer together, so that the stop post 121a that is close to the gap 100b of the other pull tab 10b first passes through the docking ring 12b, and then the other stop post 121a passes through the docking ring 12b, so that the two docking rings 12a and 12b are separated at the two gap positions, thereby unlocking the two pull tabs 10a and 10b.

[0029] By setting two baffles 121a on the pull tab 10a, and the total length of the two baffles 121a is greater than the inner diameter of the docking ring 12a, the difficulty of separating the two docking rings 12a and 12b is increased, thereby further improving the anti-theft effect. Users are familiar with this structure and can operate it skillfully without affecting its use.

[0030] like Figure 2 As shown, the stop post 121a is frustoconical in shape, and the diameter of its free end 1212a is smaller than the diameter of the fixed end 1211a and smaller than the size of the gap 100a. Thus, when interlocking or separating, the free end 1212a can pass through or out of the gap 100a, which is convenient for user operation.

[0031] The distance between the two free ends 1212a is less than the outer diameter of the docking ring 12a, so as to avoid the overall structure formed by the two stop posts 121a being too large and affecting its use.

[0032] The pull tab 10a is integrally molded to improve the connection strength between the pull rod 11a and the connecting ring 12a. Preferably, the pull tab 10a is integrally molded from metal to prevent forced damage and improve the anti-theft effect.

[0033] The docking ring 12a is circular to facilitate processing and preparation, and to facilitate relative movement between the two docking rings 12a and 12b.

[0034] like Figure 1 As shown, the interlocking pull tab also includes two connectors 13a and 13b, which are rotatably connected to the other ends of the two pull rods 11a and 11b, respectively. The connectors are used to connect to the base. By setting the connectors to connect the other end of the pull rod to the base, the pull rod can rotate relative to the connectors, thus allowing the pull rod to rotate relative to the base. This facilitates rotational operation by holding the pull rods 11a and 11b, reducing the difficulty of operation.

[0035] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
