[0060] A connecting rod assembly 41, whose fixed end is used for rotational connection with the bottom of the container body 3, and whose extended end is used for rotational connection with the inner side of the side door 31;

[0061] The limiting link 42 has one end connected to the connecting link group 41 and the other end used for rotational connection with the bottom of the container body 3. When the side door 31 is unfolded, the limiting link 42 limits the extension length of the connecting link group 41 to keep the side door 31 horizontal.

[0062] When installing the opening and closing mechanism for the container side door, the fixed end of the connecting link group 41 is used for rotational connection with the bottom of the container body 3, and the extended end is used for rotational connection with the inner side of the side door 31. One end of the limit link 42 is connected to the connecting link group 41, and the other end is used for rotational connection with the bottom of the container body 3. When the side door 31 is deployed, the limit link 42 limits the extension length of the connecting link group 41, so that the side door 31 remains horizontal. Because the limit link 42 limits the extension length of the connecting link group 41 when the side door 31 is deployed, the side door 31 remains horizontal. The horizontal side door 31 can be used as a temporary maintenance platform, which solves the problem of the existing technology that temporarily constructing a maintenance platform requires a lot of manpower and material resources, takes time to build, wastes manpower and material resources, and reduces maintenance efficiency.

[0063] like Figure 3 As shown, in some optional embodiments, a handle 311 is provided on the outer side of the side door 31 .

[0064] In this embodiment, a handle 311 is provided on the outer side of the side door 31 to facilitate opening the side door 31 .

[0065] like Figure 4 As shown, in some optional embodiments, a door lock mechanism 5 is further included, and the door lock mechanism 5 includes:

[0066] Two locking tongues 51, which are respectively arranged on the container body 3 on both sides of the side door 31;

[0067] The cross lock 52 is provided on the side door 31 , and both ends of the cross lock 52 are used to extend into the lock tongue 51 .

[0068] In this embodiment, the container also includes a door locking mechanism 5, which includes a cross lock 52 and two lock tongues 51. The two lock tongues 51 are respectively arranged on the container body 3 on both sides of the side door 31. The cross lock 52 is arranged on the side door 31, and the two ends of the cross lock 52 are used to extend into the lock tongue 51 to facilitate the locking of the side door 31.

[0069] like Figure 3 and Figure 4 As shown, in some optional embodiments, the handle 311 is rotatably connected to the side door 31, and the cross lock 52 is connected to the handle 311. The cross lock 52 is configured such that when the handle 311 is rotated, the cross lock 52 is retracted or extended to disengage from or extend into the lock tongue 51.

[0070] In this embodiment, the handle 311 is rotatably connected to the side door 31, and the cross lock 52 is connected to the handle 311. The cross lock 52 is configured such that when the handle 311 is rotated, the cross lock 52 is retracted or extended to disengage from or extend into the lock tongue 51 to facilitate unlocking.

[0071] In summary, when installing the opening and closing mechanism for the container side door, the fixed end of the connecting link group 41 is used for rotational connection with the bottom of the container body 3, and the extended end is used for rotational connection with the inner side of the side door 31. One end of the limit link 42 is connected to the connecting link group 41, and the other end is used for rotational connection with the bottom of the container body 3. When the side door 31 is deployed, the limit link 42 limits the extension length of the connecting link group 41, so that the side door 31 remains horizontal. Because the limit link 42 limits the extension length of the connecting link group 41 when the side door 31 is deployed, the side door 31 remains horizontal. The horizontal side door 31 can be used as a temporary maintenance platform, which solves the problem of the existing technology that temporarily constructing a maintenance platform requires a lot of manpower and material resources, takes time to build, wastes manpower and material resources, and reduces maintenance efficiency.
