[0002] Luggage is a general term for bags, and is a general term for various bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags and various trolley cases. Luggage is made of more diverse materials, including leather, PU, ​​polyester, canvas, cotton and linen, etc. The suitcase is divided into two parts, the upper and lower parts, by the zipper in the middle. When the zipper is opened, clothes and items can be placed. When the zipper is closed, it can be used for traveling.

[0003] The opening and closing of traditional suitcases are all covered with plastic teeth of the zipper. However, when the suitcase is filled with a lot of clothes, the plastic teeth connecting the zipper and the nylon teeth are often pulled out from the edge of the suitcase, making the suitcase unstable and unreliable.

[0004] In view of this, we carry out technological innovation based on existing products. Utility Model Content

At the same time, the structure includes rivets and self-tapping screws, the rivets penetrate in multiple layers, the self-tapping screws are located inside the suitcase, and a buckle is provided below the self-tapping screws.

[0007] Furthermore, the inner side surface of the double-layer plastic strip is in close contact with the upper and lower surfaces of the plastic teeth, and the outer surface of the double-layer plastic strip is provided with anti-reverse teeth inclined to the right.

[0008] Furthermore, the plastic frame has a three-layer structure, which is an S-shaped structure facing leftward. The second and third layers are covered with double-layer plastic strips and are designed to fit the surface of the anti-reverse teeth. A groove is provided on the first layer, and a semicircular installation groove is provided at the lower right end of the third layer.

[0009] Furthermore, the box shell is located between the first layer and the second layer of the plastic frame, and a protrusion matching the groove is provided on the surface of the box shell.

[0010] Furthermore, the rivet passes through the box shell, the second layer of the plastic frame, the first layer of the double-layer plastic strip, the plastic teeth, the second layer of the upper plastic strip, and the third layer of the plastic frame from top to bottom.

[0011] Furthermore, the self-tapping screw passes from bottom to top through the third layer of the plastic frame, the second layer of the double-layer plastic strip, the plastic teeth, the first layer of the double-layer plastic strip, and the connecting portion between the second layer and the first layer of the plastic frame.

[0012] Furthermore, the clamping block is located below the self-tapping screw, and its right side surface is also an arc-shaped structure, forming an embracing structure between the mounting groove, and the embracing object is a steel ring.

[0013] The utility model provides a luggage case multi-protection structure, which has the following beneficial effects:

[0014] The present application achieves the fixation and durability of the suitcase through a multi-layer protective structure. The entire structure is relatively flatter than others (the proportion can be referred to the left section view). Rivets and self-tapping screws are common and economical accessories, which greatly save costs and materials for production, making the product easy to promote and popularize.

[0032] The structures, proportions, sizes, etc. illustrated in this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with the technology. They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantial technical significance. Any structural modification, change in proportion or adjustment in size shall still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0033] See also Figure 1 to Figure 2 The utility model provides a technical solution: a multiple protection structure of a suitcase, including a zipper, the zipper is composed of plastic teeth and nylon teeth 2, the nylon teeth 2 are perpendicular to the plastic teeth, a double-layer plastic strip 3 is provided on the plastic teeth, and a plastic frame 4 is provided on the plastic strip. At the same time, the structure includes rivets 5 and self-tapping screws 6, the rivets 5 penetrate in multiple layers, the self-tapping screws 6 are located inside the suitcase, and a buckle 7 is provided below the self-tapping screws 6, and the buckle 7 plays the role of a limiting steel ring 12.

[0034] Furthermore, the inner side of the double-layer plastic strip 3 is in close contact with the upper and lower surfaces of the plastic teeth, and the outer surface of the double-layer plastic strip 3 is provided with anti-reverse teeth 8 inclined to the right to prevent the plastic frame 4 from separating from the plastic teeth.

[0035] Furthermore, the plastic frame 4 is a three-layer structure, which is an S-shaped structure facing leftward. The second and third layers are covered with a double-layer plastic strip 3 and are designed to fit the surface of the anti-reverse tooth 8. A groove 9 is provided on the first layer, and a semicircular mounting groove 10 is provided at the lower right end of the third layer. The block is located below the self-tapping screw 6, and its right side surface is also an arc-shaped structure, forming an embracing structure between the mounting groove 10, and the embracing object is a steel ring 12.

[0036] Furthermore, the box shell 201 is located between the first layer and the second layer of the plastic frame 4 , and a protrusion 11 matching the groove 9 is provided on the surface of the box shell 201 to prevent the plastic frame 4 from being separated from the box shell 201 .

[0037] Furthermore, the rivet 5 passes through the box shell 201, the second layer of the plastic frame 4, the first layer of the double-layer plastic strip 3, the plastic teeth, the second layer of the upper plastic strip, and the third layer of the plastic frame 4 from top to bottom, thereby fixing the entire connection part.

[0038] Furthermore, the self-tapping screw 6 passes through the third layer of the plastic frame 4, the second layer of the double-layer plastic strip 3, the plastic teeth, the first layer of the double-layer plastic strip 3, and the connecting part of the second layer and the first layer of the plastic frame 4 from bottom to top. Since the rivet 5 is at the left end of the figure and the self-tapping screw 6 is at the right end of the figure, the left and right cooperate to play a dual fixing role, and the self-tapping screw 6 is hidden in the box body, which is more beautiful in appearance.

[0039] The present application is designed to strengthen the fixation of the suitcase, and multiple fixation means: the rivet 5 fixes the suitcase shell 201, the plastic frame 4, the double-layer plastic strip 3, and the plastic teeth at the left end; the self-tapping screw 6 fixes the plastic frame 4, the double-layer plastic strip 3, and the plastic teeth at the right end; the anti-reverse teeth 8 prevent the plastic frame 4 from detaching from the double-layer plastic strip 3; the protrusions 11 and the grooves 9 prevent the plastic frame 4 from detaching from the suitcase shell 201; the figure also shows the left side cross-sectional structure of the suitcase, and the right side is also symmetrically designed, with a zipper in the middle, and the zipper is composed of a pull head (not shown in the figure, it is an ordinary zipper pull head, stuck on the nylon teeth 2), nylon teeth 2, and plastic teeth.

[0040] The drawings of the present application are schematic diagrams, which show the connection structure and relationship, not the actual size ratio of the real object. In reality, the multiple protection structure of the suitcase is very small, and the structure of the box body is very large. In reality, the multiple protection structure of the suitcase is close to the size of a zipper.
