A limiting boss ring is formed between the second corner bracket lintel connecting plate 2103 and the door end corner bracket body 2100. These limiting boss rings fix and limit the position of the lintel 24. The limiting boss rings can have a U-shaped structure.

[0076] refer to Figure 1 , Figure 8 and Figure 9 The door corner bracket 211 is a one-piece molded structure, including a cuboid door corner bracket body 2110, a corner bracket sill connecting plate 2113 and a corner bracket door corner post connecting plate 2112, all vertically mounted on the door corner bracket body 2110, and a corner bracket side beam connecting plate 2111 vertically mounted on the door corner bracket body 2110. The door corner bracket 211 is an aluminum alloy casting.

[0077] The lower end of the door corner post 23 is welded to the side of the door bottom corner piece body 2110 and the bottom corner piece door corner post connecting plate 2112.

[0078] There are multiple bottom corner bracket door end corner post connecting plates 2112, and the overall shape of the multiple bottom corner bracket door end corner post connecting plates 2112 matches the end shape of the door end corner post 23. Some bottom corner bracket door end corner post connecting plates 2112 are connected to form a rectangular frame and inserted into the rectangular columnar cavity of the door end corner post 23.

[0079] Note: In use, the bottom corner bracket door end corner post connecting plate 2112 is located on the upper surface of the bottom corner bracket body 2110.

[0080] refer to Figure 1 , Figure 8 and Figure 9 The end of the threshold 25 is welded to the side of the top corner bracket body 2100 and the bottom corner bracket threshold connecting plate 2113. There are multiple bottom corner bracket threshold connecting plates 2113, and the overall shape of the multiple bottom corner bracket threshold connecting plates 2113 matches the end shape of the threshold 25.

[0081] Both the bottom corner bracket door end corner post connecting plate 2112 and the bottom corner bracket threshold connecting plate 2113 are vertically installed on the upper surface (in the use state) of the bottom corner bracket body 2110, and the bottom corner bracket door end corner post connecting plate 2112 is located on the side of the bottom corner bracket threshold connecting plate 2113 away from the opposite side bottom corner bracket 211.

[0082] The threshold 25 is a hollow extruded aluminum alloy profile. The lower part of the end of the threshold 25 has a notch. The threshold 25 is welded to the upper surface of the door end corner piece body 2110 and to the side of the corner piece threshold connecting plate 2113. The threshold 25 is also welded to the facing side surface of the door end corner piece body 2110.

[0083] A limiting boss ring is formed between the bottom corner bracket sill connecting plate 2113 and the bottom corner bracket body 2110 of the door end. Both limiting boss rings fix and limit the sill 25. The above limiting boss rings can be a closed structure or a semi-closed structure.

[0084] Specifically, the lower surface of the end of the threshold 25 is in the form of two steps. The lower surface of the first step of the threshold 25 covers the upper surface of the door end corner piece body 2110 and is located between the two corner piece threshold connecting plates 2113. The vertical surface of the first step of the threshold 25 is connected to the surface of the corner piece threshold connecting plate 2113 facing the opposite door end corner piece 211.

[0085] The lintel 24 is not only welded to the main body 2100 of the door corner piece, but also welded to the lintel connecting plate of the corner piece, which increases the welding strength between the lintel 24 and the door corner piece 21. In addition, the lintel connecting plate of the corner piece also serves to limit the position of the lintel 24.

[0086] The threshold 25 is welded not only to the main body 2110 of the bottom corner piece of the door, but also to the threshold connecting plate 2113 of the bottom corner piece, which increases the welding strength between the threshold 25 and the bottom corner piece 211. In addition, the threshold connecting plate 2113 of the bottom corner piece also serves to limit the position of the threshold 25.

[0087] The door corner post 23 is not only welded to the main body 2100 of the top corner piece and the main body 2110 of the bottom corner piece, but also welded to the door corner post connecting plate 2102 of the top corner piece and the door corner post connecting plate 2112 of the bottom corner piece, increasing the welding strength. Furthermore, the door corner post connecting plate 2102 of the top corner piece and the door corner post connecting plate 2112 of the bottom corner piece also serve to limit the position of the door corner post 23.

[0088] The above structural design enhances the rigidity and strength of the overall structure formed by the door ends.

[0089] refer to Figure 3 The lintel 24 includes a first vertical part 241, a horizontal part 242, and a second vertical part 243 connected in sequence to form a groove with the groove opening facing upward (i.e., the cross-section is approximately "U" shaped), and openings are formed at both ends of the lintel 24. The first vertical part 241 is welded to the top corner piece 21 of the door end, and a rope loop 212 is provided on the side of the second vertical part 243 facing the first vertical part 241.

[0090] The horizontal section 242 and the second vertical section 243 serve as eaves, which is equivalent to the eaves being integrated with the lintel 24. Furthermore, the first vertical section 241, the horizontal section 242, and the second vertical section 243 all have internal reinforcing ribs, increasing the strength of the aluminum alloy door end assembly and the rigidity of the container.

[0091] In the container, the horizontal portion 242 and the second vertical portion 243 of the lintel 24 are positioned facing inward relative to the first vertical portion 241. This increases the welding strength between the lintel 24 and the upper side beam 31 in the container and facilitates the installation of the rope loop 212.

[0092] refer to Figure 2 and Figure 4 The sill reinforcement beam 28 is perpendicularly connected to the sill 25 on the same side surface. The sill reinforcement beam 28 is an aluminum alloy rectangular tube.

[0093] In the container, the other end of the sill reinforcement beam 28 is welded to the bottom crossbeam 13, which is a beam extending laterally from the bottom of the container. This increases the mechanical strength of the sill 25.

[0094] refer to Figure 4 The upper surface of the threshold 25 is provided with a protrusion with a triangular cross-section, which extends along the length of the threshold 25. The outer surface of the protrusion ( Figure 4The right-side surface (inside) is designed to facilitate rainwater drainage out of the container.

The floor is a component of the underframe in a container and defines the bottom surface of the container's interior space.

[0095] refer to Figure 1 , Figure 2 and Figure 10 The door panel assembly 22 consists of two panels, forming a double-door structure. The door panel assembly 22 is hinged to the door end post 23 via hinges 29 to open and close the opening of the rectangular frame. Door sealing strips 210 are adhered to the side surface of the door panel assembly 22 to seal any gaps on the exterior of the door panel assembly 22.

[0096] refer to Figure 7 and combined Figure 1 The L-shaped part 232 is provided with a groove for mounting the hinge 29.

[0097] refer to Figure 10 The door panel 22 comprises a door beam 2201 and a door panel 2202 welded to the inside of the door beam 2201. The door beam 2201 is divided into two upper and lower horizontal beams and two left and right side beams. The door beam 2201 is made of aluminum alloy rectangular tubing. The door panel 2202 is made of hollow extruded aluminum alloy profile.

[0098] refer to Figure 1 The anti-collision square tube 26 extends vertically and is welded to the door panel assembly 22.
