The body member 100 is connected to the two end parts of the door header 10, Figure 2 The movable corner post 200 in the extended position is 200a, and the movable corner post 200 in the retracted position is 200b. The height of the movable corner post 200 in the extended position is not lower than the door header 10. Moreover, the height of the movable corner post 200 in the extended position is lower than the top wall of the tunnel 1. The container door 30 is connected to the body member 100, and the top part of the container door 30 is in a shape suitable for the door header 10. In the utility model, the telescopic corner post 20 is arranged to allow height adjustment as required during hoisting, so that the lifting hook or lifting cable can be accurately and stably connected to the corner post, thereby improving hoisting efficiency and reducing safety risks. The arch-shaped door header 10 and the telescopic corner post 20 jointly enhance the stability of the end region of the container door 30. The arch-shaped door header 10 can bear greater vertical and transverse loads, and the telescopic corner post 20 provides additional support and fixing points, so that the whole door end region is more stable and reliable.

[0074] In some embodiments of the utility model, the container door 30 comprises a door upright 31 and a door panel 33. The door upright 31 is fixedly connected to the body member 100, and the door upright 31 is provided with a hinge 32. The door panel 33 is connected to the hinge 32. The door upright 31 is fixedly connected to the body member 100, thereby providing a firm support structure for the door panel 33 and ensuring that the door panel 33 can remain stable during opening and closing and is not prone to deformation or damage.

[0075] In the utility model, the door header 10 and the door upright 31 are both connected to the body member 100 of the telescopic corner post 20, so that the overall stability of the door end assembly can be ensured, and deformation or damage caused by vibration or external force can be reduced. The telescopic corner post 20 increases the telescopic function while not affecting the original performance.

[0076] Optionally, the door panel 33 is further provided with a door lock 50. The door lock 50 improves the safety performance and airtightness of the container as a whole.

[0077] In the utility model, the telescopic corner post 20 is located at the corner part of the container. Specifically, the telescopic corner post 20 is located at the four corner parts of the container.

[0078] In some embodiments of the present invention, the container further includes a roof panel 40. The roof panel 40 has an arched structure with a high center and low ends along its length, and the shape of the roof panel 40 is adapted to the lintel 10. The arched roof panel 40 structure fully utilizes the upper limit of the vehicle, thereby achieving the purpose of expanding the container capacity.

[0079] The specific implementation of the telescopic corner post 20 is described below.

[0080] Reference Figures 3 to 6 The utility model provides a telescopic corner post 20, which can be adjusted according to the lifting environment and the specific size of the container to ensure that the height of the corner post matches the lifting requirements of the arc-top container, thereby improving the safety of the lifting process and ensuring the stability and accuracy of the container during the lifting process.

[0081] The telescopic corner post 20 includes a body member 100 , a movable corner post element 200 , a stopping member 300 and a locking member 400 .

[0082] The body member 100 is connected to the container body and is located at the corner of the container body to enhance the rigidity and stability of the container body. Optionally, the body member 100 is constructed as a hollow columnar structure.

[0083] The movable corner post 200 is movably connected to the main member 100 between an extended and retracted position. In this embodiment, the main member 100 serves as the fixed portion of the telescopic corner post 20, connected to the container body. While inheriting the basic functions and position of a traditional corner post, it also adds an adjustable length portion of the movable corner post 200 to accommodate various lifting and transportation requirements. Optionally, the movable corner post 200 can be sleeved into the interior of the main member 100. Optionally, the movable corner post 200 can be constructed as a hollow columnar structure. The cross-sectional shape of the movable corner post 200 matches that of the main member 100, ensuring a tight fit between the movable corner post 200 and the main member 100 during extension and retraction. This reduces gaps or misalignment caused by shape mismatches, thereby enhancing the stability of the overall structure and preventing deformation or damage due to uneven force during lifting or transportation.

[0084] The stop member 300 cooperates with the locking member 400 to lock the movable corner post 200 in the extended position, thereby ensuring the stability and safety of the corner post during the hoisting process.

[0085] The stop member 300 is connected to the main body member 100 and has a connecting groove 301. The connecting groove 301 is configured to engage with the locking block 410 of the locking member 400. The cross-sectional shape of the locking block 410 matches the opening profile of the connecting groove 301, ensuring that the locking block 410 can smoothly enter and lock within the connecting groove 301. The opening profile of the connecting groove 301 is non-circular. When the non-circular connecting groove 301 engages with the locking block 410 on the locking member 400, it effectively prevents the locking block 410 from accidentally unlocking or slipping out when subjected to forces in an unintended direction.

[0086] The locking member 400 is connected to the movable corner post 200. The locking member 400 can move closer to or further away from the stop member 300 as the movable corner post 200 moves. The locking member 400 is rotatably connected to the movable corner post 200. The rotatable connection between the locking member 400 and the movable corner post 200 allows the locking block 410 to be rotated to a locked position when needed, thereby tightly fitting into the connection slot 301 of the stop member 300.

[0087] Among them, reference Figure 7 When the movable corner post 200 moves to the extended position, the locking block 410 connects to the stop member 300 and can rotate to the locked position, locking the movable corner post 200 in the extended position. When the locking block 410 is in the locked position, at least a portion of the locking block 410 is offset from the connecting groove 301 along the axial projection of the locking member 400, and at least a portion of the locking member 400 is located on both sides of the locking block 410 in the axial direction. When the locking block 410 is in the locked position, the locking member 400 limits the axial movement of the locking block 410. That is, when the locking block 410 is in the locked position, the locking member 400 limits the upward and downward movement of the locking block 410, ensuring the stability of the movable corner post 200 during the lifting process.

[0088] With this solution, operators can easily adjust the length of the movable corner post 200 and lock or unlock it with a simple rotation operation, which not only improves work efficiency but also reduces operational difficulty and error rate.

[0089] In some embodiments of the present invention, the movable corner post 200 is provided with a slide groove 201, and a stop member 300 is slidably connected to the slide groove 201. In this embodiment, the stop member 300 serves as a slide rail for the movable corner post 200, further improving the stability of the movable corner post 200 during extension and retraction. The engagement of the stop member 300 with the slide groove 201 also strengthens the connection strength between the movable corner post 200 and the main member 100.

[0090] In some embodiments of the present invention, the locking member 400 is connected to the lower end of the movable corner post 200. When the movable corner post 200 is in the extended position, at least a portion of the stop member 300 is offset from the slide slot 201. In this embodiment, the stop member 300 is exposed outside the movable corner post 200, allowing the locking block 410 to engage more directly and effectively, thereby simplifying the locking process and improving locking efficiency.

[0091] In some embodiments of the present invention, the stop member 300 includes at least two spaced-apart stop blocks, and the spaced-apart stop blocks form a snap-in groove 302. Specifically, the stop block includes an upper limit portion 310, an intermediate portion 320, and a lower limit portion 330 that are sequentially connected, and the upper limit portion 310 and the lower limit portion 330 extend from the upper and lower ends of the intermediate portion 320 toward one side thereof. Optionally, when the locking block 410 is in the locked position, the upper limit portion 310 is located above the locking block 410, constituting a limit for the upward movement of the locking block 410 in the axial direction. The lower limit portion 330 is located below the locking block 410, constituting a limit for the downward movement of the locking block 410 in the axial direction.

[0092] A connecting groove 301 is formed between the spaced lower limiting portions 330 , and the connecting groove 301 allows the locking block 410 to pass through and enter the engaging groove 302 .

[0093] A snap-fit ​​groove 302 is formed between the spaced middle portions 320, and the locking block 410 at the locked position is snap-fitted into the snap-fit ​​groove 302. The snap-fit ​​groove 302 provides a precise snap-fit ​​position for the locking block 410, thereby achieving a stable locking effect.

[0094] In this embodiment, the stop member 300 provides a secure locking mechanism and a position limiting function, thereby improving the safety of the entire lifting system. During the lifting process, the movable corner post 200 can maintain its predetermined position, preventing safety accidents caused by accidental movement.

[0095] In some embodiments of the present invention, the locking member 400 further includes a rotating shaft 420, which is rotatably connected to the movable corner post 200 and fixedly connected to the locking block 410. In this embodiment, the rotating shaft 420 serves as a connecting link between the movable corner post 200 and the locking block 410, achieving a coordinated movement between the two. When the movable corner post 200 moves, the rotating shaft 420 drives the locking block 410 to move synchronously. Simultaneously, the rotating shaft 420 drives the locking block 410 to rotate relative to the movable corner post 200, thereby achieving locking and unlocking functions.

[0096] In some embodiments of the utility model, telescopic angle column 20 still includes linear drive module 500, rotating shaft 420 can move under the drive of linear drive module 500.
