[0042] like Figure 1 As shown, this utility model discloses a container 200. The container 200 has a front end 201 and a rear end 202 that are opposite to each other along the length direction of the container 200. The front end 201 of the container 200 is close to the front of the transport vehicle, and the rear end 202 of the container 200 is close to the rear of the transport vehicle. The front end 201 of the container 200 is provided with a gooseneck groove. Specifically, the gooseneck groove is provided at the bottom of the front end 201 of the container 200 to cooperate with the groove on the gooseneck chassis, thereby reducing the overall height of the vehicle, making it suitable for use in roads, tunnels, and bridges where the passage height is restricted. Both the front end 201 and the rear end 202 of the container 200 can be provided with openable and closable doors, so that cargo can be loaded and unloaded at both the front end 201 and the rear end 202.

[0043] like Figure 2 As shown, this utility model discloses a threshold 100 for installation onto the front end 201 of a container 200. For example... Figure 3 As shown, the threshold 100 includes a main body 110 and a support portion 120. The main body 110 is constructed in an arched shape along the length of the threshold 100, that is, the main body 110 arches upward along the length of the threshold 100, forming a structure that gradually decreases from the middle to both ends. Two support portions 120, which are spaced apart along the length of the threshold 100, are respectively connected to the main body 110 and located below the main body 110.

[0044] According to the present invention, the threshold 100 has an arched main body 110, which improves the strength of the threshold 100. During the loading process, the main body 110 moves downward under the weight of the cargo, thereby ensuring that the threshold 100 is in a near-horizontal state, maintaining good contact with components such as the door seal strip, and ensuring good sealing of the door.

[0045] The camber C of the main body 110 is less than 10 mm, for example, 0 < C < 10 mm. The main body 110 can be made of flat steel. Therefore, the thickness of the flat steel can be adjusted as needed to manufacture main bodies 110 of different heights. For example, as... Figure 4AAs shown, the height H of the main body 110 can be from 20mm to 35mm. Preferably, the main body 110 is constructed as an axisymmetric structure symmetrical along the central axis AX. The support portion 120 can be welded to the lower surface of the main body 110 to support the main body 110. The two support portions 120 can be respectively connected to the two ends of the main body 110 along the length direction of the sill 100, and the space between the two support portions 120 forms the opening of the gooseneck groove. In the installed state where the sill 100 is installed to the container 200, the length direction of the sill 100 can be the width direction of the container 200.

[0046] like Figure 4A As shown, in one embodiment, the support portion 120 is a square tube, meaning that the support portion 120 does not have an opening in its circumferential direction. The top wall of the support portion 120 is connected to the main body portion 110, for example, by welding.

[0047] The support portion 120 can also be a C-shaped tube with an opening, wherein the opening faces the main body portion 110 or faces away from the main body portion 110. The opening of the support portion 120 means that the support portion 120 has an opening in its circumferential direction, that is, the support portion 120 has three walls.

[0048] Figure 4B The image shows an embodiment where the opening faces the main body 110. In this embodiment, the free end of the side wall 122 of the support portion 120 is connected to the main body 110, and the main body 110 closes the opening of the support portion 120 to prevent foreign objects from entering the support portion 120.

[0049] In an embodiment not shown, the opening faces away from the main body 110, i.e., downwards. In this embodiment, the top wall of the support 120 is connected to the main body 110. The threshold 100 also includes a closing portion 130, which is connected to the opening to close it. The closing portion 130 may be connected to the free ends of the two side walls 122 of the support 120 to close the opening and prevent foreign objects from entering the support 120. The closing portion 130 may be a sealing plate extending along the length of the threshold 100.

[0050] like Figures 4C to 4F As shown, when the support portion 120 is a C-shaped tube, the support portion 120 includes a flange 121 connected to the free end of at least one sidewall 122 of the support portion 120. The support portion 120 may have one flange 121 connected to the free end of one sidewall 122, or it may have two flanges 121 respectively connected to the free ends of two sidewalls 122. The flange 121 may be integrally formed with the sidewall 122 of the support portion 120, i.e., formed by bending the sidewall 122. Alternatively, the flange 121 may be a separate component separate from the sidewall 122, connected to the free end of the sidewall 122 by welding.

[0051] like Figure 4C and Figure 4E As shown, the flange 121 of the support portion 120 can be bent toward the inside of the support portion 120. For example... Figure 4D As shown, the flange 121 of the support portion 120 can be bent outwards towards the support portion 120. For example... Figure 4F As shown, one of the two flanges 121 is bent toward the outside of the support portion 120, and the other is bent toward the inside of the support portion 120.

[0052] like Figure 4C and Figure 4D As shown, when the opening of the support portion 120 faces away from the main body portion 110, the closing portion 130 can be connected to the flange 121 of the support portion 120 to close the opening and prevent foreign objects from entering the support portion 120.

[0053] like Figure 4E and Figure 4F As shown, when the opening of the support portion 120 faces the main body portion 110, the flange 121 can be connected to the main body portion 110 to connect the support portion 120 to the main body portion 110.

[0054] The container 200 in this utility model may include the aforementioned threshold 100.

[0055] The container 200 according to this utility model includes the aforementioned threshold 100. The main body 110 of the threshold 100 is arched, thereby improving the strength of the threshold 100. During cargo loading, the main body 110 moves downward under the weight of the cargo, thereby ensuring that the threshold 100 is in a near-horizontal state, maintaining a good fit with components such as the door seal strip, and ensuring good sealing of the container door.
