Container House Fixed Buckle
Container house fixed buckles mainly include types such as twist locks, bridge fittings, stacking cones, and lashing bars. Their function is to achieve a firm connection between containers through mechanical structures, preventing displacement or overturning during transportation or use.

Twist Lock
Twist locks are the core components for container fixation and come in three types: manual, semi-automatic, and fully automatic. Their principle involves inserting a rotating lock head (such as a mushroom-shaped or spiral structure) into the corner fitting holes of the container to achieve a connection between the container body and the base or between container bodies. For example, semi-automatic twist locks automatically lock under gravity during loading and require an operating rod to unlock during unloading, making them suitable for frequent loading and unloading scenarios at ports. Fully automatic twist locks rely on the container's weight to trigger locking, improving operational efficiency.Bridge Fitting
Bridge fittings are used for the horizontal connection of adjacent containers. By inserting lock hooks at both ends into the corner fitting holes and rotating the adjusting nuts, multiple rows of containers form an integrated structure. For example, installing bridge fittings on top of containers stacked on a deck enhances overall wind resistance, preventing the upper containers from detaching in strong winds and waves.Stacking Cone
Stacking cones come in single-headed and double-headed varieties. Placed between upper and lower containers or on in-cabin guide rails, they prevent horizontal sliding of containers through vertical fixation. For example, when loading a 20-foot container in a 40-foot container slot in a cabin, stacking cones are required to secure the smaller-sized container.Lashing Bar and Turnbuckle
Lashing bars, in combination with turnbuckles (adjustable spiral fasteners), form a tensioning device. By creating an 'X'-shaped lashing on one side of the container, they secure it to the deck or lashing bridge. For containers stacked to a great height, lashing bars can transfer external forces to the ship's structure, reducing damage from bumps.
Application Scenarios:
- Maritime Transportation: Through twist locks, bridge fittings, and lashing systems, container ships can secure multiple layers of containers, maintaining stability even in ten-level storms.
- Modular Housing: When unfolding prefabricated container houses, buckles are used to fix the walls, floors, and roof structures, ensuring居住 safety.
- Temporary Buildings: Construction site mobile homes are connected through quick-assembly container frames and buckles, enabling rapid construction and repeated disassembly.
