Description

Technical Field

[0001] The utility model relates to the technical field of luggage boxes, in particular to a keel structure and a box body connection structure. Background Art

[0002] A suitcase, also known as a travel case or trolley case, is a type of luggage used to carry items when traveling. It's typically used to store clothing, personal care items, and souvenirs needed for travel. Zippered suitcases (also known as zippered cases) are commonly found on the market. These lightweight, conveniently opened and closed with a zipper, make them popular.

[0003] However, the existing zipper case and zipper connection structure generally first opens a circle of grooves around the upper side edge of the suitcase body, then sews the zipper (usually including two zippers stacked in parallel, one for connecting the suitcase to the cover shell, and the other for connecting the inner lining partitions of the suitcase) to the bottom of the U-shaped strip (the shape and length of the U-shaped strip match the groove), and then extends the U-shaped strip with the zipper into the groove and sews it again. In this way, the existing zipper and suitcase need to be fixed by two sewing processes, which is complicated, time-consuming, labor-intensive, and inefficient. In addition, if the zipper is damaged, it is difficult to remove and difficult to replace. Utility Model Content

[0020] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1-5 As shown, the present embodiment proposes a keel structure and a box body connection structure, comprising a U-shaped bar 2 that can be placed in a surrounding groove 1 on the upper side of the suitcase, wherein the opening of the U-shaped bar 2 is flush with the open end of the surrounding groove 1, and comprises a first side portion 3, a connecting portion 4 and a second side portion 5, wherein the connecting portion 4 is fixedly connected between the first side portion 3 and the second side portion 5 to form a U-shaped structure, and further comprises a first clip structure and a second clip structure, wherein the first clip structure is arranged between the U-shaped bar 2 and the surrounding groove 1, and the second clip structure is arranged between the zipper 6 and the U-shaped bar 2.

[0022] In this way, the zipper 6 is first clamped on the side of the U-shaped strip 2 through the second clamping structure, and then the U-shaped strip 2 with the zipper 6 is clamped in the surrounding groove 1 on the upper side of the suitcase through the first clamping structure. The installation is convenient, the process is simple, and time and labor are saved. It not only improves work efficiency, but also makes it convenient to disassemble and replace the zipper at any time if it is damaged.

[0023] Furthermore, the first engaging structure includes a first engaging block and a first engaging slot that engage with each other. The first engaging block is provided on one of the bottom end of the connecting portion 4 and the bottom wall of the surrounding groove 1, while the first engaging slot is provided on the other. This allows for easy assembly and disassembly of the U-shaped bar 2 within the surrounding groove 1, eliminating the need for sewing and providing simple and convenient fixing.

[0024] Specifically, the structures of the first card block and the first card slot may refer to the existing structures, and will not be repeated herein.

[0025] The fixed side portion of the zipper 6 is provided with a second latch block along its length, and the exteriors of both the first side portion 3 and the second side portion 5 are provided with second latching slots that engage with the second latch block. The second latch block engages with the second latching slot on the exterior of the first side portion 3 or with the second latching slot on the exterior of the second side portion 5. This improves the efficiency of connecting the zipper 6 to the U-shaped strip 2. Simply pick up the U-shaped strip 2 and insert the second latch block on the zipper 6 directly into the second latching slot on any side of the strip, without having to adjust the orientation of the U-shaped strip 2. This makes connection quick and easy.

[0026] Specifically, embodiment 1: Figure 2-3 As shown, the second clamping block is configured as a T-shaped bar, the T-shaped bar extends along the length direction of the zipper, and the second clamping groove is configured as a T-shaped slot, and the T-shaped bar can be inserted into the T-shaped slot for connection.

[0027] Example 2: Figure 4-5As shown, the second clamping block includes a plurality of spherical clamping beads 7, which are arranged along the length of the zipper 6. The second clamping slot is configured as an arcuate through-slot 8 extending along the length of the side of the U-shaped strip 2. The end of the second clamping block can pass through one end of the arcuate through-slot 8 and pass out from the other end. The plurality of spherical clamping beads 7 are sequentially inserted into the arcuate through-slot 8. Specifically, the arcuate through-slot 8 can be configured as a cylindrical through-slot or a tightly cylindrical through-slot. In this way, the spherical clamping beads 7 can be easily inserted into the interior of the arcuate through-slot 8. The specific shapes and structures of the second clamping block and the second clamping slot can also be other shapes and structures. For details, please refer to the existing structure and will not be repeated herein.

[0028] Among them, since the opening of the U-shaped bar 2 faces outward when it is inserted into the surrounding groove 1, in order to prevent dust or stolen goods from entering and damaging the U-shaped bar 2, and also to ensure the overall appearance of the suitcase, a buckle strip is also installed at the opening of the U-shaped bar 2. The buckle strip is set to a rectangular structure and extends along the length direction of the U-shaped bar 2.

[0029] It should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature.
