The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also have other implementations.

[0086] First embodiment

[0087] like Figures 1 to 8As shown, this embodiment provides a door end structure. The door end structure is used for a container. The door end structure includes a door frame 1 and a container door 2. The door frame 1 is used to be set at one end of the container. The door frame 1 includes two corner posts 12. The length direction of the corner posts 12 extends in the vertical direction. The two corner posts 12 are used to be set on both sides of the container respectively. The door frame 1 also includes a bottom corner piece 11 located at the bottom of each corner post 12, and a threshold 14 connected between the two bottom corner pieces 11. The container door 2 includes a door leaf 21 and a rubber strip 22 located around the door leaf 21. The door leaf 21 is connected to the corner post 12 through a hinge 13.

[0088] This article describes the characteristics of the door end structure based on the length direction of the container, the height direction of the container and the width direction of the container when the door end structure is used for the container. Among them, the length direction of the corner column is parallel to the height direction of the container.

[0089] Herein, the inner end of component a along direction b is: when component a is used in a container, the end of component a along direction b is close to the center of the container. The outer end of component a along direction b is: when component a is used in a container, the end of component a along direction b is far from the center of the container. The inner side of component a along direction b is: when component a is used in a container, the side of component a along direction b is close to the center of the container. The outer side of component a along direction b is: when component a is used in a container, the side of component a along direction b is far from the center of the container.

[0090] For example, the inner end of the body 111 in the vertical direction is the end of the body 111 in the vertical direction close to the center of the container when the corner fitting is used for a container. The outer end of the body 111 in the vertical direction is the end of the body 111 in the vertical direction away from the center of the container when the corner fitting is used for a container. The inner side of the body 111 in the vertical direction is the side of the body 111 in the vertical direction close to the center of the container when the corner fitting is used for a container. The outer end side of the body 111 in the vertical direction is the side of the body 111 in the vertical direction away from the center of the container when the corner fitting is used for a container.

[0091] In this article, the inner end edge of a component is the edge of component a close to the center of the container along the length direction of the container when component a is used in a container. The outer end edge of a component is the edge of component a away from the center of the container along the length direction of the container when component a is used in a container. The inner end surface of a component is the surface of component a close to the center of the container along the length direction of the container when component a is used in a container. The outer end surface of a component is the surface of component a away from the center of the container along the length direction of the container when component a is used in a container.

[0092] a. Inner side of component a: When component a is used in a container, the edge of component a along the width direction of the container close to the center of the container. a. Outer side of component a: When component a is used in a container, the edge of component a along the width direction of the container away from the center of the container. a. Inner side of component a: When component a is used in a container, the surface of component a along the width direction of the container close to the center of the container. a. Outer side of component a: When component a is used in a container, the surface of component a along the width direction of the container away from the center of the container.

[0093] For example, the inner end edge of the main body 111 is an edge of the main body 111 along the length direction of the container close to the center of the container when the main body 111 is used in the container.

[0094] like Figures 3 to 5 As shown, the bottom corner piece 11 includes a body portion 111 and a connecting portion 112. The body portion 111 is provided with a first top surface 1111 located at the top thereof, and a first outer edge surface 1113 formed by vertically extending downwardly from a first outer end edge 1115 of the first top surface 1111. The first outer end edge 1115 extends along the width direction of the container.

[0095] The connecting portion 112 is located on the inner side of the main body 111 along the width direction of the container and is connected to the main body 111. The connecting portion 112 is provided with a second top surface 1121 located at the top thereof, an inner side surface 133 of the corner piece formed by the inner side edge 1125 of the corner piece of the second top surface 1121 extending vertically downward, and a second outer edge surface 1123 formed by the second outer end edge 1124 of the second top surface 1121 extending vertically downward. The first top surface 1111 is higher than the second top surface 1121. The inner side edge 1125 of the corner piece extends along the length direction of the container. The second outer end edge 1124 extends along the width direction of the container. The first outer edge surface 1113 is coplanar with the second outer edge surface 1123. The sill end surface 143 of the sill 14 is butted against the inner side surface 133 of the corner piece of the bottom corner piece 11. The sill top surface 141 of the sill 14 is flush with the second top surface 1121. The threshold outer end surface 142 of the threshold 14 is flush with the second outer edge surface 1123 of the bottom corner piece 11 .

[0096] like Figure 3 As shown, the bottom of the corner post 12 is connected to the first top surface 1111 of the bottom corner fitting 11. The corner post 12 is located on the side of the second top surface 1121 close to the first top surface 1111. As a result, the structure of the door end structure is simple. The corner post outer edge surface 121 of the corner post 12 is flush with the first outer edge surface 1113 of the bottom corner fitting 11. The door leaf 21 is connected to the corner post 12 by a hinge 13. The lip edge of the rubber strip 22 around the door leaf 21 is pressed on the corner post outer edge surface 121, the first outer edge surface 1113 and the second outer edge surface 1123 of the bottom corner fitting, and the outer end surface 142 of the door sill.

[0097] like Figure 5 As shown, the height of the bottom corner piece 11 is H11. The distance between the first top surface 1111 of the main body 111 and the bottom surface 130 of the bottom corner piece 11 is also H11. The distance between the second top surface 1121 of the connecting portion 112 and the bottom surface 130 of the bottom corner piece 11 is H13. The height difference between the first top surface 1111 and the second top surface 1121 is H12. The width of the connecting portion 112 is W12. The height of the threshold 14 is also H13. The length of the threshold 14 is W11. Figure 2 and Figure 5 , the height of the threshold 14 can be lowered so that the threshold top surface 141 is flush with the second top surface 1121. In this way, the height dimension of the doorway formed by the door frame 1 of the container can be increased by a height H12. At the same time, the width dimension of the doorway formed by the door frame 1 is increased by W12 on one side, that is, the width dimension of the doorway formed by the door frame 1 is increased by twice W12 in total.

[0098] In this embodiment, the threshold top surface 141 can be made flush with the second top surface 1121 to lower the height of the threshold 14, thereby increasing the height of the doorway formed by the door frame 1; at the same time, the width of the doorway formed by the door frame 1 is increased, thereby being able to load and unload large goods with larger width and height dimensions.

[0099] like Figure 4 As shown, optionally, the first top surface 1111 and the second top surface 1121 of the bottom corner piece 11 are connected by a transition surface 132. The transition surface 132 is a vertical plane. Thus, the volume of the bottom corner piece 11 is small.

[0100] like Figure 4 As shown, the main body 111 has a first outer end face 1112. The bottom of the first outer edge face 1113 has a surface bottom edge 1116 and a surface inner side edge 1117. The upper end of the surface inner side edge 1117 is connected to the inner end of the surface bottom edge 1116. The surface bottom edge 1116 extends along the width direction of the container. The surface inner side edge 1117 extends along the height direction of the container. The surface bottom edge 1116 extends to the end of the first outer end face 1112 along a direction substantially parallel to the first top face 1111 (e.g., the length direction of the container) to form a first step surface 1114. In this way, along the length direction of the container, the first outer end face 1112 and the first outer edge face 1113 are parallel and spaced apart. Along the length direction of the container, the first outer end face 1112 is located on the outside of the first outer edge face 1113. The inner side edge 1117 extends along a direction substantially parallel to the transition surface 132 (e.g., the length direction of the container) to the end of the first outer end surface 1112 to form a transition step surface 134. The second outer edge surface 1123 is provided with an observation hole 114 connected to the connecting cavity. As a result, the structure of the main body 111 is simple.

[0101] Optionally, a lashing hole 113 communicating with the body cavity is provided on the first outer end surface 1112. The container can be fastened through the lashing hole 113 to fix the container.

[0102] like Figure 6 and Figure 7 As shown, there is a connection cavity inside the connection part 112. A first twist lock hole 115 communicating with the connection cavity is provided at the bottom of the connection part 112. Thus, the stacked containers can be locked by the twist lock hole and the twist lock.

[0103] like Figure 7 As shown, the first twist lock holes 115 on the bottom corner pieces 11 on the left and right sides of the door end structure of the container are arranged in pairs. The center distance between the first twist lock holes 115 on the left and right sides is W1, so as to meet the installation and locking of the lock during transportation.

[0104] like Figure 8 As shown, the outer side edge 135 of the corner fitting of the first top surface 1111 extends vertically downward to form the outer side surface 131 of the corner fitting. That is, the outer side surface 131 of the corner fitting is provided on the outer side of the body portion 111 along the width direction of the container. The outer side surface 131 of the corner fitting is provided with a side hole 117 connected to the cavity of the body. Therefore, the container can be tied or lifted through the side hole 117 to fix or transport the container.

[0105] Alternatively, if Figures 3 to 5 As shown, the main body 111 also has a main body cavity inside. The connecting cavity is connected to the main body cavity. The second outer edge surface 1123 is provided with an observation hole 114 connected to the connecting cavity, so that the situation inside the bottom corner piece 11 can be observed through the observation hole 114, such as locking and binding.

[0106] Alternatively, if Figures 3 to 5 As shown, the connecting portion 112 has a second outer end surface 1122. The second outer end surface 1122 is coplanar with the first outer end surface 1112. The connecting bottom edge 1126 of the second outer edge surface 1123 extends along a direction substantially parallel to the second top surface 1121 (e.g., the length direction of the container) to the top of the second outer end surface 1122 to form a second step surface 1127. As a result, the weight of the bottom corner piece 11 is small.

[0107] Second embodiment

[0108] like Fig. 9 and Fig.10 As shown, the bottom of the main body is provided with a second twist lock hole 216. That is, the bottom of the bottom corner piece has both a first twist lock hole 215 and a second twist lock hole 216. Along the width direction of the container, the first twist lock hole 215 is located inside the second twist lock hole 216.

[0109] like Figure 8As shown, the first twist lock hole 215 and the second twist lock hole 216 on the bottom corner pieces on the left and right sides of the door end structure of the container are arranged in pairs. The center distance between the pair of first twist lock holes 215 on the left and right sides is W1. The center distance between the pair of second twist lock holes 216 is W2. This can meet the installation and locking of multiple sets of locks during transportation.

[0110] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0111] Third embodiment

[0112] like Fig.11 and Fig.12 As shown, the first top surface 3111 and the second top surface 3121 are connected by a transition surface 332. The transition surface 332 is an inclined surface. Therefore, the strength of the bottom corner piece is large.

[0113] The transition outer end edge 3321 of the transition surface 332 extends vertically downward to form a transition outer edge surface 336. The transition bottom edge 3361 of the transition outer edge surface 336 extends along a direction substantially parallel to the transition surface 332 (e.g., the length direction of the container) to the end of the first outer end surface 1112 to form a transition step surface 335. The lower end of the transition step surface 335 is connected to the second step surface through a vertical surface.

[0114] The first outer edge surface 3113 , the second outer edge surface 3123 and the transition outer edge surface 336 are coplanar.

[0115] The other configurations of the third embodiment are substantially the same as those of the first embodiment, and will not be described in detail here.

[0116] Fourth embodiment

[0117] like Fig.13 and Fig.14 As shown, the top of the bottom corner piece is recessed downward to form a groove 430. The width direction of the groove 430 is parallel to the length direction of the container. An upper edge of the groove 430 is located on the first top surface. The side of the groove 430 away from the first outer end surface 4112 includes a first outer edge surface 4113 and a second outer edge surface 4123. When the container door is closed, the lip edge of the rubber strip 42 is located in the groove 430 and presses the first outer edge surface 4113 and the second outer edge surface 4123.

[0118] like Fig.13 and Fig.14As shown, the groove 430 includes a first groove section 431 and a second groove section 432. The first groove section 431 is located in the main body 411. The length direction of the main body 411 is parallel to the width direction of the container. The end of the first groove section 431 away from the connecting portion 412 is a blind end. The second groove section 432 is located at the connection between the main body 411 and the connecting portion 412.
