Description

Technical Field

[0001] This invention relates to the field of luggage accessories, and in particular to a luggage zipper that is easy to install and a snap-fit ​​structure using the zipper. Background Technology

[0002] Suitcases, also widely known as travel cases or rolling suitcases, are essential containers used by people to carry clothing, personal care products, souvenirs, and other necessities when traveling. Based on structural features and ease of use, suitcases on the market are currently mainly divided into two categories: zippered suitcases and framed suitcases. Zippered suitcases, with their lightweight advantage, have won the favor of many consumers.

[0003] The assembly process of existing zipper cases involves a complex installation of the shell and zipper. Traditional installation methods typically require manual sewing of the zipper, which is not only time-consuming and labor-intensive but also dependent on the skill level of the operators, resulting in low production efficiency and difficulty in ensuring consistent quality across batches. Utility Model Content

[0004] To address the issue of complex zipper installation, this application provides an easy-to-install bag zipper and a snap-fit ​​structure for using the bag zipper.

[0005] Firstly, this application provides a bag zipper that is easy to install, using the following technical solution:

[0006] A bag zipper that is easy to install includes a zipper body and zipper fabric connected to both sides of the zipper body. The outer side of the zipper fabric is connected to a snap-fit ​​part. The snap-fit ​​part includes snap-fit ​​rings fixed to the front and back of the zipper fabric. The snap-fit ​​rings on both sides are symmetrically arranged with respect to the zipper fabric. The zipper fabric is snapped to the inner frame of the bag through the snap-fit ​​part.

[0007] By adopting the above technical solution and setting a snap-fit ​​ring, the zipper fabric can be directly snapped into the groove of the bag's inner frame, achieving the connection without manual sewing, which saves time and is convenient.

[0008] Optionally, the snap ring is O-shaped when projected along the length of the zipper.

[0009] Optionally, the snap ring includes a spiral strip, which is bent to form a plurality of O-shaped teeth, the distance between adjacent O-shaped teeth being less than the diameter of the spiral strip.

[0010] By adopting the above technical solution, the spiral strip is bent into a spiral to form several O-shaped teeth, so that the O-shaped teeth are continuous and the distance between adjacent O-shaped teeth is smaller than the diameter of the spiral strip, thus ensuring the density of the O-shaped teeth and ensuring the flexibility of the snap ring, making it smoother and less prone to jamming when threading the snap ring.

[0011] Optionally, the snap ring is sewn to the zipper fabric with yarn.

[0012] By adopting the above technical solution, the snap ring is sewn to the zipper fabric with yarn, thereby fixing the snap ring.

[0013] Optionally, the snap ring is provided with a fixing strap in the middle to facilitate the threading of the yarn.

[0014] By adopting the above technical solution and setting a fixing strap, the yarn can be better fixed during sewing.

[0015] Optionally, the snap ring is a zipper tooth.

[0016] By adopting the above technical solution, the snap ring can be made from any type of zipper tooth, thus broadening its applicability.

[0017] Secondly, this application provides a snap-fit ​​structure using the above-mentioned bag zipper, employing the following technical solution:

[0018] A snap-fit ​​structure for using the above-mentioned bag zipper includes a middle frame body fixed to the bag, wherein the middle frame body has an installation groove for the snap-fit ​​part to pass through.

[0019] By adopting the above technical solution, the zipper fabric and the bag shell can be easily connected by snapping the snap ring into the mounting groove, eliminating the need for sewing, making assembly more convenient and saving labor costs.

[0020] Optionally, the mounting groove extends through the middle frame body and includes a receiving cavity for accommodating the snap ring and a through groove for the zipper fabric to pass through, the width of which is less than the thickness of the snap ring.

[0021] By adopting the above technical solution, during installation, it is only necessary to gradually insert the snap ring into the installation groove from one end until the entire snap ring is inserted into the installation groove to complete the installation. This is convenient, quick, and saves labor costs. After the snap ring is inserted into the installation groove, it can be snapped in place. Even when the zipper fabric is under tension, the snap ring can be firmly snapped into the receiving cavity due to the narrow width of the groove.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By setting double-layer snap rings on both sides of the zipper fabric, when connecting it to the bag frame, simply insert the snap rings into the mounting groove of the bag frame to achieve snap-fit, saving time and effort, improving assembly efficiency and reducing assembly costs.

[0024] The snap ring is composed of several continuous and closely spaced O-shaped teeth, making the snap ring more flexible and flexible when bending. Therefore, it is easier to insert the snap ring into the mounting groove and avoids jamming. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0028] This application discloses a bag zipper that is easy to install.

[0029] Example 1: Refer to Figure 1 The bag zipper includes a zipper body 1, a zipper fabric 2, and a snap fastener 3. One side of the zipper fabric 2 is connected to the zipper body 1, and the other side is connected to the snap fastener 3. The zipper fabric 2 and the zipper body 1, as well as the zipper fabric 2 and the snap fastener 3, can be connected by injection molding or sewing.

[0030] The locking part 3 includes locking rings 4 fixed to the front and back of the zipper fabric 2. The locking rings 4 can be made of malleable spiral strips, which can be made of nylon, resin, or metal. The spiral strips are bent in a spiral shape to form several O-shaped teeth. Then, the center line is wrapped around the locking rings 4 to form chain teeth. Finally, the locking rings 4 are sewn together with the zipper fabric 2 using a zipper sewing machine. After sewing, the distance between adjacent O-shaped teeth is smaller than the diameter of the spiral strip, thereby ensuring the density of the O-shaped teeth and ensuring the flexibility of the locking rings 4 when they are inserted. After sewing, the projection of the locking rings 4 along the length of the zipper is O-shaped, and the front and back edges of the zipper fabric 2 are sewn with locking rings 4. For a more secure sewing, a fixing strap 6 is inserted in the middle of the locking rings 4. The fixing strap 6 can be made of webbing or fabric strips.

[0031] Example 2: The difference from Example 1 is that in this example, the snap ring 4 is a zipper tooth. The type of zipper is not limited and can be any type of zipper.

[0032] This application also provides a snap-fit ​​structure that utilizes the aforementioned bag zipper. This snap-fit ​​structure includes a middle frame body 7 fixed to the edge of the bag shell. The middle frame body 7 and the bag shell are connected by a slotted connection. A mounting groove 8 is provided on the side of the middle frame body 7 facing away from the bag shell for the snap-fit ​​ring 4 to pass through. The mounting groove 8 extends along the length of the middle frame body 7 and includes a receiving cavity 9 for accommodating the snap-fit ​​ring 4, as well as a through groove 10 for the zipper fabric 2 to pass through. The width of the through groove 10 is less than the thickness of the snap-fit ​​ring 4 and only allows the zipper fabric 2 to pass through. An opening for the snap-fit ​​ring 4 to pass through is provided at one end of the mounting groove 8.

[0033] The implementation principle of the above-mentioned snap-fit ​​structure for bag zippers in this embodiment is as follows: the zipper fabric 2 and the snap-fit ​​ring 4 are directly sewn together. During assembly, only one end of the zipper fabric 2 with the snap-fit ​​ring 4 needs to be inserted through the opening into the mounting groove 8 of the middle frame body 7. Then, the snap-fit ​​ring 4 is slid along the mounting groove 8 so that the entire snap-fit ​​ring 4 is inserted into the mounting groove 8, thereby achieving the snap-fit ​​between the zipper fabric 2 and the middle frame body 7. For further reinforcement, glue can be applied inside the mounting groove 8 for further fixation.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
