[0002] As an important carrier for cargo storage and transportation, the safety and stability of the container door is crucial. Currently, during the opening and closing process of the traditional container door, the lack of effective anti-rebound device often leads to the rebound of the door after opening due to external forces such as wind, handling operation impact, etc. This not only may cause collision injury to the surrounding operators, but also may cause obstruction in the cargo loading and unloading process, and even lead to safety accidents such as cargo falling. In the existing anti-rebound technology, some devices use simple mechanical limiting structure, but there are problems of fixed limiting angle and inconvenient adjustment, which cannot meet the needs of multi-angle opening and closing fixation of the door in different scenarios. For example, the traditional limiting device can usually only realize single-angle locking, and it is difficult to flexibly adapt to the size of the door opening and closing, resulting in low practicality of the device.

[0022] Embodiment one
[0023] Please refer to Figures 1-5 , an anti-rebound assembly for a container door, comprising a bottom plate one 30 and a bottom plate two 40;
[0024] Specifically, the bottom plate one 30 is fixedly installed inside the box door 20 by bolts, and the side of the bottom plate one 30 away from the box door is fixedly connected with a mounting seat one 31, and the mounting seat one 31 is rotatably connected with a rotating rod one 32 through a connecting shaft;
[0025] The bottom plate two 40 is fixedly installed on the inner wall of the top of the compartment 10 by bolts, and a mounting sleeve 41 is fixedly connected to the side of the bottom plate two 40 away from the top of the compartment. A rotating shaft 43 is rotatably connected in the mounting sleeve 41, and a connecting sleeve 42 is fixedly sleeved on the bottom of the rotating shaft 43 beyond the bottom of the mounting sleeve 41. A rotating rod two 44 is fixedly connected to the outer wall of the connecting sleeve 42, and a connecting seat 45 is fixedly connected to the side of the rotating rod two 44 away from the connecting sleeve 42. The side of the rotating rod one 32 away from the mounting one 31 is rotatably connected to the connecting seat 45 by a connecting shaft.
[0026] The bottom plate two 40 is further provided with a limiting assembly on the side away from the top of the compartment 10. Since the opening angle of the box door 20 is not fixed, in order to improve the practicability of the whole anti-rebound assembly, the rotating limiting of the rotating shaft 43 is realized by the limiting assembly, so that the box door 20 can be fixed at multiple angles when opening and closing.
[0027] Specifically, the limiting assembly comprises a mounting seat two 50 fixedly connected to the side of the bottom plate two 40 away from the top of the compartment 10. The mounting seat two 50 is located on one side of the mounting sleeve 41, and a gap is left between the mounting seat two 50 and the connecting sleeve 42 to avoid the mounting seat two 50 interfering with the 180° rotation of the connecting sleeve. A pressing plate 51 is rotatably connected to the mounting seat two 50 by a connecting shaft. The side of the pressing plate 51 is located below the rotating shaft 43, and a limiting rod 52 is fixedly connected to the top of the pressing plate 51 away from the limiting rod 52. A connecting rod 53 is fixedly connected to the top of the side of the pressing plate 51 away from the limiting rod 52. A sleeve 54 is connected to the top of the connecting rod 53, and the sleeve 54 is fixedly connected to the bottom plate two 40.
[0028] A plurality of limiting holes are uniformly arranged at the bottom of the rotating shaft 43 with the shaft center as the center point. The rotation limiting of the rotating shaft 43 is realized by the insertion between the limiting rod 52 and the limiting hole.
[0029] That is, the bottom plate one 30 is installed on the inner side of the box door 20, and the bottom plate two 40 is installed on the inner wall of the top of the compartment 10 (if it does not interfere, the bottom plate two 40 can also be installed on the inner wall of the bottom of the compartment 10). The bottom plate one 30 and the bottom plate two 40 are kept at the same installation height. The rotation of the rotating rod one 32 and the rotating rod two 44 can cooperate with the opening and closing of the box door 20. Taking the opening of the box door 20 as an example, when the box door 20 is opened outward, the rotating rod one 32 is driven to rotate, and the rotating rod two 44 is pulled to rotate with the rotation of the rotating rod one 32. After the box door 20 is opened to the appropriate position, the limiting rod 52 is inserted into the limiting hole on the rotating shaft 43 through the pressing plate 51, so as to realize the position fixing of the opened box door 20, and avoid the rebound from hurting the workers.
[0030] When the box door 20 is opened, the opening angle of the box door 20 can be adjusted to align the limiting rod 52 with the limiting hole to be inserted.
[0031] The sleeve 54 is a threaded sleeve, the connecting rod 53 is a threaded rod, the connecting rod 53 is rotatably sleeved in the sleeve 54, and the bottom of the connecting rod 53 is rotatably connected to the top of the pressing plate 51; the pressing plate 51 is pulled down or pushed up on one side by rotating the connecting rod 53, so that the limiting rod 52 is pulled out of the limiting hole to realize the rotation of the rotating shaft 43 or the limiting rod 52 is inserted into the limiting hole to realize the limiting and fixing of the rotating shaft 43;
[0032] When the box door 20 is closed, the connecting rod 53 is rotated to pull down the pressing plate 51 and pull out the limiting rod 52 from the limiting hole, so as to facilitate the closing of the box door 20.
[0033] By Figure 1 The maximum opening of the box door 20 is displayed, so that the mounting seat two 50 does not hinder the rotation of the rotating rod two 44.
[0034] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
