Description

Technical Field

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

[0002] Existing luggage typically consists of a front body, a rear body, and a frame connecting the two. The frame, in addition to its connection, also requires decorative trim to enhance the overall aesthetics of the luggage. However, these trims do not completely enclose the trunk, leaving the trunk exposed and diminishing the overall aesthetics of the luggage.

[0003] In order to solve the technical problem that the trunk lacks aesthetic appeal due to leakage of the trunk, patent publication number CN216293277U discloses an invisible frame structure and a suitcase using the frame structure, which specifically discloses a flexible frame trim, a connecting piece and a frame-shaped card slot; the left and right sides of the frame trim are covering edges, and the frame trim also includes an insert, which is arranged perpendicular to the covering edge, and sliding edges are provided on both sides of the insert; one side of the slot body of the frame-shaped card slot is provided with an inner protrusion supporting the sliding edge, and the insert and the slot body of the frame-shaped card slot are embedded and connected, and the slot body of the frame-shaped card slot is covered by the covering edge; when the frame trim is pulled, the sliding edge can move along the inner protrusion, and after the frame trim moves to the head and the tail are connected, it is closed and connected by the connecting piece to form a complete frame.

[0004] Although this frame structure can solve the technical problem of luggage box body leakage, it still has some shortcomings. For example, the flexible frame trim, connectors, frame-shaped card slots and other accessories in this frame structure are independent of each other. Therefore, when assembling the luggage box, the frame trim needs to be pulled along the inner protrusion, and the frame trim needs to be moved to the front and rear ends to connect, and then connected by connectors to form a complete frame. This assembly method that requires additional connectors to connect the front and rear ends of the frame trim is relatively complex and makes assembly less convenient and quick.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content
