[0022] The utility model discloses an auxiliary door-closing device and a container with the same. The container includes a chassis 5, a container door 4 arranged above the side of the chassis 5, and an auxiliary door-closing device arranged on the side of the chassis 5. The auxiliary door-closing device is located beside the door-closing device of the container door 4 and below the container door 4, aiming to press the container door 4 so that the container door 4 will not rebound and does not affect the door-closing device.

[0023] Refer to Figure 1 and Figure 2 In this embodiment, taking the container door 4 as a pair of opening doors as an example, the container door 4 is arranged above the container chassis 5. The door-closing device includes a lock rod 61 and a lock seat 62. The lock rod 61 is movably arranged on the container door 4, and the lock seat 62 is welded to the side of the chassis 5. Both door leaves are fixedly connected to the chassis 5 through a set of door-closing devices. Therefore, in this embodiment, the auxiliary door-closing device needs to be arranged on the chassis 5 and between the two sets of door-closing devices to press the two door leaves simultaneously. Refer to Figure 3 The auxiliary door-closing device includes a fixing structure 1, a rotating structure 2 and a pressing structure 3. One end of the rotating structure 2 is rotatably connected to the fixing structure 1, and the other end is provided with the pressing structure 3.

[0024] The fixing structure 1 includes two fixing seats 11 and a fastener. Combining Figure 1 、 Figure 3 and Figure 4 Both fixing seats 11 are welded to the chassis 5 and are symmetric about the midline of the pair of opening doors. Both fixing seats 11 are provided with through holes, and both ends of the fastener are respectively connected to the two fixing seats 11 through the through holes. The fastener includes a hexagonal flange bolt 12 and a fastening nut 13. The hexagonal flange bolt 12 passes through the two through holes in sequence, and the fastening nut 13 is used to tighten and fix at its end, thereby axially limiting the hexagonal flange bolt 12 on the fixing seat 11.

[0025] Refer to Figure 3 and Figure 5 The rotating structure 2 includes a rotating plate and a screw fixing block 26. The cross section of the rotating plate is L-shaped, including a larger plate 21 and a smaller plate 22 that are perpendicular to each other. A triangular fixing block 23 is welded between the included angles of the larger plate 21 and the smaller plate 22 to enhance the structural stability. One end of the larger plate 21 is welded with two connecting blocks 24 with shaft holes 25. The connecting blocks 24 are respectively located on both sides of the end. The connecting blocks 24 and the smaller plate 22 are respectively located at the two opposite ends of the larger plate 21. The connecting blocks 24 are located between the two fixing seats 11. When the hexagonal flange bolt 12 passes through the fixing seat 11, it also passes through the shaft hole 25, so that the rotating plate rotates around the hexagonal flange bolt 12.

[0026] The screw fixing block 26 is welded to the smaller plate 22 and is internally provided with a threaded through hole for cooperating with the screw 32 in the pressing structure 3. Besides the screw 32, the pressing structure 3 further includes a pressing plate 31. Combining Figure 3 and Figure 6 , the screw 32 passes through the screw fixing block 26 and the smaller plate 22 and is threadedly connected to the screw fixing block 26. One end of the screw 32 is welded with a pressing plate 31, and the other end is welded with a handle 33. Both the pressing plate 31 and the screw fixing block 26 are located in the inner space of the rotating plate. The inner space of the rotating plate refers to the space enclosed by the larger plate 21 and the smaller plate 22. That is, the handle 33 is located in the outer space of the rotating plate, and the corners of the handle 33 are rounded to facilitate manual rotation of the screw 32 to adjust the pressing degree.

[0027] When the rotating plate rotates to the position where the smaller plate 22 is in the vertical plane, the pressing plate 31 can be pressed against the container door 4 under the control of the screw 32, and can be combined with Figure 2 . A rubber pad 34 is pasted on the side of the pressing plate 31 facing away from the screw 32. The rubber pad 34 is in direct contact with the container door 4, which can avoid damage caused by mechanical collision and better protect the coating on the container door 4.

[0028] To prevent the excessive rotation of the screw 32 from causing the inability to control the movement range of the pressing plate 31, a limiting baffle 27 is welded to one side of the screw fixing block 26. The limiting baffle 27 and the smaller plate 22 are respectively located on both sides of the screw fixing block 26. The pressing structure 3 further includes two pressing plate connecting rods 35 that are symmetric about the screw 32. The pressing plate connecting rods 35 are parallel to the screw 32. One end of the pressing plate connecting rod 35 is fixed to the pressing plate 31 by welding or bolt connection, and the other end passes through the limiting through hole 28 opened in the limiting baffle 27, and a limiting portion 36 is provided at this end. The limiting portion 36 is larger than the limiting through hole 28 and cannot pass through. This enables the pressing plate connecting rod 35 to assist the movement of the pressing plate 31 on the one hand and limit the movement range of the pressing plate 31 on the other hand when the screw 32 is rotated.

[0029] Combining Figure 1 and Figure 2 , when this auxiliary door closing device is in use, the rotating plate needs to be installed on the fixed seat 11 first. After the container door 4 is closed to a certain angle, the rotating plate is lifted, and the handle 33 is rotated to push the pressing plate 31 so that the container door 4 is in a pressed state, which is convenient for the locking rod 61 of the container door 4 to fall into the lock seat 62 of the underframe 5 to lock the container door 4. If in situations such as transportation where the auxiliary door closing device is not required, the rotating structure 2 and the pressing structure 3 can be disassembled through fasteners. The disassembly and assembly are convenient, and they can be stored separately without affecting the use of the container.

[0030] In summary, the utility model uses an auxiliary door closing device to tightly fix the container door 4 when the container door is closed, prevent the container door 4 from rebounding and shaking, and enable the container locking rod 61 to better cooperate with the lock seat 62 for fixation.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
