Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of improved suitcases, specifically relating to a suitcase that facilitates the positioning of the zipper fabric, preventing the zipper fabric from twisting and deforming after molding due to improper positioning; at the same time, it results in a more aesthetically pleasing suitcase during use. Background Technology
[0002] Suitcases are a common household item, often carried by people when traveling for convenient packing and transporting luggage. Most suitcases consist of a lid and a body connected by a zipper. During assembly, operators need to separately shape and stitch the two zipper teeth onto the lid and body. In practice, the zipper teeth are relatively difficult to install, resulting in low efficiency. Furthermore, operators frequently make significant errors during installation, causing uneven surfaces after the zipper is closed, affecting the overall appearance of the suitcase.
[0003] To address this, we developed a method for facilitating the positioning of the zipper fabric, preventing distortion and deformation of the formed zipper fabric due to improper positioning; at the same time, it results in a more aesthetically pleasing suitcase during use. Summary of the Invention
[0004] The purpose of this invention is to provide a suitcase that facilitates the positioning of the zipper fabric, preventing the zipper fabric from twisting and deforming after molding due to improper positioning; at the same time, it results in a more aesthetically pleasing suitcase during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a suitcase, comprising a case shell and a lid, wherein the outside of the case shell is provided with a receiving cavity; the lid is disposed on the case shell to cover the receiving cavity; a pair of zipper fabrics are provided between the edge of the receiving cavity and the edge of the lid; after the outer edge of the zipper fabric corresponding to the edge of the lid is aligned with the edge of the lid, a U-shaped first decorative strip is fitted on it and sewn together; a U-shaped second decorative strip is fitted on the edge of the receiving cavity; the outer edge of the zipper fabric corresponding to the edge of the receiving cavity is aligned with the bottom edge of the second decorative strip and sewn together.
[0006] Preferably, the zipper fabric is located outside the second decorative strip; a first protrusion is provided on the outside of the open end of the second decorative strip, and the bent part of the zipper fabric contacts the first protrusion to position the zipper fabric.
[0007] Preferably, the zipper fabric is located on the outside of the box lid.
[0008] Preferably, one side of the lid is hinged to the corresponding side of the receiving cavity, and the other side, upper, and lower ends of the lid are provided with matching zipper fabrics between them and the edge of the receiving cavity.
[0009] Compared with the prior art, the present invention provides a suitcase with the following advantages:
[0010] In the suitcase described in this utility model, the outer shell and lid are respectively connected to the corresponding zipper fabric, which facilitates the positioning of the zipper fabric and prevents the zipper fabric from twisting and deforming after molding due to improper positioning; at the same time, the first decorative strip is not exposed when in use, making the appearance more beautiful. Attached Figure Description
[0011] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-2 This utility model provides a technical solution: a suitcase, including a case shell 1 and a case lid 2. The case shell 1 has an external cavity (not shown). The cavity is used to store frequently used items for quick access. The case lid 2 is disposed on the case shell 1 to cover the cavity. A matching zipper fabric 3 is provided between the edge of the cavity and the edge of the case lid 2. In this embodiment, one side of the case lid 2 is hinged to the corresponding side of the cavity, and the other side, upper, and lower ends of the case lid 2 are provided with matching zipper fabric 3 between them and the edge of the cavity.
[0017] After the outer edge of the zipper fabric 3 corresponding to the edge of the lid 2 is aligned with the edge of the lid 2, a U-shaped first decorative strip 4 is fitted on it and sewn together; at the same time, the zipper fabric 3 is located on the outside of the lid 2; a U-shaped second decorative strip 5 is fitted on the edge of the receiving cavity; the outer edge of the zipper fabric 3 corresponding to the edge of the receiving cavity is aligned with the bottom edge of the second decorative strip 5 and sewn together; the zipper fabric 3 is located outside the second decorative strip 5; a first protrusion 51 is provided on the outside of the open end of the second decorative strip 5, and the bent part of the zipper fabric 3 contacts the first protrusion 51 to position the zipper fabric 3.
