Description

Technical Field

[0001] The utility model relates to a luggage connector, in particular to a single-side luggage corner connector. Background Art

[0002] When making luggage that is formed by bending a flat plate, the box shell of the box body is bent from the bottom panel to the surrounding areas to form a side shell body, and the borders of two adjacent side shell bodies need to be connected by corners. The existing manufacturing process is complicated, and flat-seam glue connection is mostly used, that is, the prepared corners are covered on the borders of two adjacent side shell bodies and glued with glue. This method is time-consuming and labor-intensive. After gluing, the transition of the box corners is not smooth, the undulations are too large, it is extremely unsightly, and the adhesion is not strong, and it is easy to fall off.

[0003] In addition, Chinese patent CN217937450U discloses a luggage box connection structure, wherein the connection structure is arranged on two box shells of the luggage box, the box shell includes a bottom shell and four side shells formed by extending and bending the four sides of the bottom shell outward, the connection structure is arranged at the junction of any two adjacent side shells of the box shell and plays a connecting role, the connection structure includes a main connecting plate, two T-shaped protrusions are respectively arranged on the main connecting plate along its length direction, slots are formed on both sides of the T-shaped protrusions, a decorative plate is fixed in the slots on the opposite sides of the two T-shaped protrusions, and the two adjacent side shells on the box shell are respectively fixed in the outer slots of the two T-shaped protrusions. The manufacturing method is simple and easy to operate, and the positioning is accurate. The main connecting plate has an arc corner to make the transition at the corner smooth, and a decorative plate is inserted in the slot, which makes the luggage very beautiful. However, in this structure, two T-shaped protrusions are provided, and a separate decorative plate is required between the two T-shaped protrusions. The operation is not simple enough, this process cannot be omitted, and the appearance needs to be improved. In addition, the main connecting plate and the T-shaped protrusion are at the same height. On the aluminum frame luggage, due to the height difference between this place and the adjacent shell, the aluminum frame needs to be manually polished to be smooth during edging, which is inconvenient to operate.

[0005] Technical solution: In order to solve the above technical problems, the improved single-sided box corner connector described in the utility model includes a box corner connecting plate, on which a decorative panel connector is provided, and the upper end of the decorative panel connector is higher than the upper end of the box corner connecting plate.

[0006] Furthermore, the trim panel connector is a T-shaped connector.

[0007] Furthermore, the box corner connecting plate is an arc-shaped connecting plate, and reinforcing ribs are provided on the inner side of the arc-shaped connecting plate.

[0008] Furthermore, a connecting hole is provided on the box corner connecting plate.

[0009] Furthermore, one decorative panel connector is provided, and the decorative panel connector is provided on one side of the vertical center line of the box corner connecting plate.

[0010] Furthermore, the box corner connecting plate and the decorative panel connecting piece are integrally formed.

[0011] Furthermore, the box corner connecting plate and the decorative panel connecting piece are plug-connected.

[0012] Furthermore, a card slot is provided on the box corner connecting plate, a connecting card strip is snap-connected in the card slot, and the connecting card strip is connected to the decorative panel connecting piece.

[0013] Furthermore, the top of the decorative panel connecting piece is either flat or arc-shaped.

[0014] Furthermore, the box corner connecting plate and the box shell are connected by one of ultrasonic welding, seaming, riveting and gluing.

[0015] Beneficial effect: Compared with the prior art, the utility model has the following significant advantages: a single-sided decorative panel connector is adopted, which is changed from the previous double-sided to the current single-sided. The decorative panels can be connected to the single-sided groove, which saves the previous process of requiring a separate decorative panel in the middle of the two sides, saves time and effort, and has a higher appearance. The upper end of the decorative panel connector is higher than the upper end of the box corner connecting plate, which changes the previous structural form in which the main connecting plate and the T-shaped protrusion have the same height. The raised part of the decorative panel connector section can improve the connection strength at the edging, and because there is only the thickness of the decorative panel connector section at this place, the aluminum frame does not need manual polishing when edging, so the edging can be made smooth, saving costs. Reinforcing ribs are provided on the inner side of the arc-shaped connecting plate to effectively improve the overall strength. Connecting holes are provided on the box corner connecting plate to make the installation of the external corner more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
