Description

Technical Field

[0001] This utility model relates to the technical field of luggage zipper structure, and in particular to a luggage shell expansion zipper structure. Background Technology

[0002] As an essential tool for modern travel, the core function of a suitcase is to provide users with efficient storage space while ensuring structural strength. Traditional hard-sided suitcases (mainly made of PC, ABS, PP, aluminum-magnesium alloy, etc.) are favored for their excellent protection and aesthetics, but their fixed structure also brings a significant drawback: the volume cannot be changed. When returning from a trip, users often have more luggage due to shopping or carrying gifts, and the fixed-volume suitcase cannot meet their needs, forcing users to either purchase additional luggage allowance or use another bag, causing many inconveniences during the journey.

[0003] The existing built-in zipper extension structure of suitcases is relatively complicated to install, and is usually installed by sewing it to the suitcase shell, which results in high production and manufacturing costs.

[0004] There is a need for a luggage shell expansion zipper structure that can solve the problems mentioned above. Utility Model Content

[0005] This utility model provides a luggage shell expansion zipper structure, which solves the problems of complex installation and high cost of existing luggage expansion structures by technically modifying the existing luggage structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An extended zipper structure for a suitcase shell includes a suitcase frame body and an extended zipper assembly. The suitcase frame body is provided with a shell mounting groove. The suitcase shell includes an upper shell and a lower shell. There are two suitcase frame bodies. The upper shell and the lower shell are respectively fitted into the shell mounting groove of the suitcase frame body. An extended zipper assembly for expanding and contracting the suitcase volume is installed between the two suitcase frame bodies.

[0007] Preferably, the extended zipper assembly includes a zipper body, a zipper fixing end, an extended fabric edge, and a fixing fabric end. The zipper body, the zipper fixing end, and the extended fabric edge are sewn together by the fixing fabric end. The extended zipper assembly is fixedly installed on the luggage frame body through the zipper fixing end. The luggage frame body located at the upper and lower boxes is connected by the zipper body and the extended fabric edge. When the zipper body is closed, the luggage box is in a contracted state; when the zipper body is opened, the luggage box is in an expanded state.

[0008] Preferably, the zipper fixing end portion, the zipper body portion, and the extended fabric edge portion are arranged in a top-to-bottom overlapping manner, and the fixing fabric end wraps around and covers the overlapping position of the zipper body portion, the zipper fixing end portion, and the extended fabric edge portion, and the zipper body portion, the zipper fixing end portion, and the extended fabric edge portion are sewn and fixed by stitching.

[0009] Preferably, the outer end of the zipper fixing end is provided with a reinforced fabric edge, and the luggage frame body is provided with a zipper mounting groove, and the reinforced fabric edge is installed inside the zipper mounting groove.

[0010] Preferably, the luggage frame body is provided with an inner bag zipper groove on the inner side of the luggage shell, and the inner bag zipper groove is used to install the inner bag zipper structure.

[0011] The beneficial effects of this utility model are as follows: This invention maintains the original dimensions of the suitcase under normal conditions by using a high-strength zipper to keep it closed. When additional capacity is needed, the zipper is opened, allowing the suitcase to unfold and release extra volume. Furthermore, the zipper structure is installed through the suitcase frame, which has a zipper mounting slot. The reinforcing fabric edge of the zipper assembly can be threaded through this slot for installation, eliminating the need for direct sewing to the suitcase shell. This makes assembly easier and reduces manufacturing costs. Attached Figure Description

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] Please see Figure 1-3As shown, this utility model provides a luggage shell expansion zipper structure, including a luggage frame body 1 and an expansion zipper assembly 2. The luggage frame body 1 is provided with a shell mounting groove 11. The luggage shell includes an upper shell 3 and a lower shell 4. There are two luggage frame bodies 1. The upper shell 3 and the lower shell 4 are respectively fitted into the shell mounting groove 11 of the luggage frame body 1. An expansion zipper assembly 2 for expanding and shrinking the luggage volume is installed between the two luggage frame bodies 1.

[0015] Furthermore, in order to achieve the fixed installation effect and expansion function of the extended zipper assembly 2, the extended zipper assembly 2 includes a zipper body part 21, a zipper fixed end part 22, an extension fabric edge part 23, and a fixed fabric end 24. The zipper body part 21, the zipper fixed end part 22, and the extension fabric edge part 23 are sewn together by the fixed fabric end 24. The extended zipper assembly 2 is fixedly installed on the luggage frame body 1 through the zipper fixed end part 22. The luggage frame body 1 set at the upper box shell 3 and the lower box shell 4 is connected by the zipper body part 21 and the extension fabric edge part 23. When the zipper body part 21 is closed, the luggage shell is in a contracted state. When the zipper body part 21 is opened, the luggage shell is in an expanded state.

[0016] Furthermore, the zipper fixing end portion 22, the zipper main body portion 21, and the extended fabric edge portion 23 are arranged in a top-to-bottom overlapping manner on one side. The fixing fabric end 24 wraps around and covers the upper and lower sides of the overlapping position of the zipper main body portion 21, the zipper fixing end portion 22, and the extended fabric edge portion 23, and sews the zipper main body portion 21, the zipper fixing end portion 22, and the extended fabric edge portion 23 together with a sewing thread to fix them in place.

[0017] The zipper body 21, the zipper fixing end 22, and the outer fabric ends of the extended fabric edge 23 overlap each other, and then the overlapping parts are wrapped by the fixing fabric end 24 and sewn together to connect the three together.

[0018] Furthermore, in order to facilitate the quick and easy installation of the extended zipper assembly 2, the outer end of the zipper fixing end portion 22 is provided with a reinforced fabric edge 221, and the luggage frame body 1 is provided with a zipper mounting groove 12, and the reinforced fabric edge 221 is installed inside the zipper mounting groove 12.

[0019] Furthermore, the luggage frame body 1 is also provided with an inner pocket zipper groove 13 on the inner side of the luggage shell. The inner pocket zipper groove 13 is used to install the inner pocket zipper structure. The inner pocket zipper structure is connected to the inner pocket installed in the luggage, which is convenient to install and has more diverse functions.

[0020] Furthermore, in order to save product costs and reduce the overall weight of the frame, the luggage frame body 1 is also provided with a hollow through slot 14.

[0021] This application maintains the original dimensions of the suitcase under normal conditions by using a high-strength zipper to close it. When additional capacity is needed, the zipper is opened, allowing the suitcase to unfold and release extra volume. Furthermore, the zipper structure is installed through the suitcase frame body, which has a zipper mounting slot 12. The reinforcing fabric edge 221 of the zipper assembly 2 can be threaded through and installed in the zipper mounting slot 12, eliminating the need for direct sewing to the suitcase shell. This makes assembly more convenient and reduces manufacturing costs.
