[0027] Corner fitting body 1: The interior is designed as a hollow cavity 2. One side of the corner fitting body 1 is concave to form a rectangular side recess 3, which facilitates mating with the rectangular side recess block 7 of the adjacent container for precise positioning. The other side features a rectangular side recess 5, within which an insert frame 9 is securely fixed by screws. A hollow rectangular side recess block 7 is fixed to the outside of the insert frame 9. The inside of the insert frame 9 is open, and the outside portion perfectly matches the shape of the rectangular side recess 3. This design significantly improves the wear resistance and positioning accuracy of the corner fitting, extending its service life.

[0028] External hole design: A first external hole 4 and a second external hole 6 are centrally located on each side of the corner piece body 1. A third external hole 8 is located on the outer side of the rectangular insert 7. These three holes are identical in shape and correspond to each other on both sides, facilitating bolt fastening to the container body or other connectors. This multi-hole design provides flexible installation and enhances the stability of the connection.

[0029] Outer end hole design: The front and rear end faces of the corner piece body 1 are respectively centrally provided with a first outer end hole 12 and a second outer end hole 13, which have the same shape and correspond to each other front and back, and are used to cooperate with the rear corner piece connector to achieve horizontal connection between containers.

[0030] Internal Connection Structure: Fixed vertical plates 14 are fixed to the front and rear ends of both interior sides of the corner fitting body 1. Connecting spring rods 15 are equidistantly mounted on the outer ends of the vertical plates. A pressure plate 16 is secured to the outer ends of each pair of connecting spring rods 15. The pressure plate 16 consists of a rectangular portion 17 and an inclined portion 18. The inclined surface of the inclined portion 18 faces the first and second outer end holes 12, 13, facilitating smooth entry and tightening of the connector. Performance Description: The unique combination of spring rods and pressure plates ensures a secure lock on the connector, effectively preventing loosening during transport.

[0031] Connection area 19: Between the front and rear ends of the corner piece body 1 and the pressure plate 16, along the outer ends of the first and second outer holes 12, 13, a connection area 19 is formed, providing ample space for the clamp to move and lock.

The upper lifting hole facilitates container handling and installation using lifting tools, while the lower lifting hole serves no other purpose but primarily connects to the container. Due to different installation locations, the first and second lifting holes 10, 11 will flip, so they are designed to have identical shapes. This corresponding lifting hole design improves the convenience and safety of lifting operations.

[0033] Working principle: At the four corners of one side of the container, the embedded frame 9 is fixed in the side rectangular groove 5 by screws, and the first outer hole 4, the first hanging hole 10, the second hanging hole 11, the first outer end hole 12 or the second outer end hole 13 are connected to the container to complete the installation of this corner piece; at the four corners of the other side of the container, the second outer hole 6, the first hanging hole 10, the second hanging hole 11, the first outer end hole 12 or the second outer end hole 13 are connected to the container to complete the installation of this corner piece; the rectangular embedded block 7 of the corner piece on one side of the container is set outward, and the rectangular embedded groove 3 of the corner piece on the other side is set outward.

[0034] When adjacent containers are arranged, the placement and positioning of the two containers are achieved by embedding the side rectangular embedding block 7 into the side rectangular embedding groove 3; the clamping piece of the rear corner piece connector is inserted into the two adjacent first outer end holes 12 or the two adjacent second outer end holes 13, and then the threaded rod of the corner piece connector is rotated with a wrench to move the clamping piece inward, and the clamping piece enters the connection area 19 along the inclined portion 18 of the pressure plate 16, and the connecting spring rod 15 pushes the pressure plate 16 to tighten the clamping piece of the corner piece connector. The two clamping pieces on each corner piece connector clamp the corner pieces of the two adjacent containers.
