Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, and in particular relates to a snap-fit ​​front-opening luggage. Background Technology

[0002] In modern travel, suitcases, as essential tools for storing and carrying belongings, directly impact the user experience through their design and practicality. Most suitcases on the market today consist of a body and a lid, forming a basic frame. A pull rod is located on the back of the suitcase for easy dragging, and wheels are installed on the bottom of both the body and lid for flexible movement. This basic design, to a certain extent, meets people's basic needs for carrying belongings during daily travel.

[0003] However, existing suitcases have many shortcomings in terms of structural connections and functional design that urgently need improvement. For example... Figure 1 and Figure 2 As shown, in the connection structure between the box body 1 and the lid 2, the common method in the prior art is to cover the edges of the box body 1 and the lid 2 with Z-shaped soft plastic frames 7, and then cover the two single-layer fabric edges 61 of a regular zipper (a regular zipper includes two single-layer fabric edges 61, zipper teeth 51 and zipper pull) with the soft plastic frames 7, and then sew the positions where the soft plastic frames 7 cover the single-layer fabric edges 61 to form a seam line 71, thereby achieving the connection and initial closure of the box body 1 and the lid 2.

[0004] This connection method presents significant structural strength issues. Because the Z-shaped soft plastic frame 7 is relatively soft, the seam connection between it and the ordinary zipper single-layer fabric edge 61 is quite weak. During frequent use of the suitcase, especially after multiple opening and closing operations, and when subjected to external pressure and impact during transportation, the seam 71 is highly susceptible to unraveling or breakage. Once the seam is damaged, the connection between the suitcase body 1 and the lid 2 will loosen, and in severe cases, it may even cause the lid 2 to separate from the suitcase body 1, rendering the suitcase unusable and significantly shortening its lifespan.

[0005] Furthermore, existing suitcases have a relatively simple functional design, relying solely on the closing of the body (1) and lid (2) to seal the storage space, lacking an additional opening mechanism at the front. In practical use, users often encounter situations where they need to access items inside the suitcase, especially those placed near the front, requiring them to fully open the entire suitcase. This is not only cumbersome but also, in public places such as airports and train stations, fully opening the suitcase exposes the contents, increasing the risk of loss or theft, and wasting the user's time and energy.

[0006] Therefore, the inventors dedicated themselves to designing a suitcase to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a snap-fit ​​front-opening suitcase, which not only effectively improves the structural strength and service life of the suitcase, but also adds a front opening function to enhance the user's convenience.
