AI Technical Summary

Technical Problem

Existing non-standard small-sized containers cannot be adapted to container ship transportation during sea transport, resulting in increased transportation costs. Furthermore, the processing and recycling costs of the connecting frames are high, making it impossible to achieve disassembly and reuse.

Method used

Design a container corner fitting connection structure that enables quick locking and unlocking through the rotating pins and handles of the connector and corner fitting. The connector and corner fitting are detachable and reusable. A symmetrical connection plate and strut are used for connection, and a limiting threaded groove and a limiting pin are used for locking and limiting.

Benefits of technology

It enables rapid connection and disassembly of container corner fittings, reduces processing and recycling costs, improves transportation efficiency, and has the advantages of being detachable and reusable, ensuring the safety and reliability of connection performance.

Abstract

This utility model discloses a container corner fitting connection structure, including a connector with corner fittings connected to both ends. The connector includes a connecting plate with a pad and a boss fixed to its outer and inner sides, respectively. A rotating pin is fixed on the block, rotatably passing through the pad, connecting plate, and boss in sequence. The rotating pin extends out of the boss and is fixed with a rotating handle. A connecting groove is provided on the side wall of the corner fitting, the pad is fitted into the connecting groove, and the block extends into the corner fitting from the connecting groove. The rotating handle is configured to drive the block to rotate, so that the block is fitted into the connecting groove and / or the length direction of the block is perpendicular to the length direction of the connecting groove, thereby unlocking and / or locking the connector and the corner fitting. The connection and locking process of the connector and corner fitting is convenient and quick, and has the advantages of being detachable and reusable. Four corner fittings can be connected simultaneously by four connectors, which can effectively restrict the movement of four container corner fittings, simplify the structure, and reduce costs.
