AI Technical Summary
The container after reducing the number of locking rods is reduced during the shipping process, which can easily lead to damage to the box and limit its circulation and transportation.
The door frame reinforcement is added to the container door frame structure, and is installed at the gap of the door frame body close to the inside of the container. It is fixed by welding to provide structural reinforcement to ensure that the switching process of the end door is not affected.
The stacking capacity and rigid resistance of containers have been improved, and the relevant strength test requirements of the standard box can be passed to ensure that they are not restricted during transportation.

Abstract
Description
Technical Field
[0001] The utility model relates to a container, in particular to a container door frame structure with three locking rods. Background Art
[0002] Containers have become a standard means of transport for multimodal transport. Four locking rods are installed on the end doors of common standard containers. Figure 1 , Figure 2 In some use cases, in order to conveniently open or close the container end door, the number of end door locking rods is reduced to three, and its structure is as follows Figure 3 As shown in the figure. After the number of locking rods is reduced, the container's ability to resist stacking and rigidity during sea transportation is reduced to a certain extent. If it is mixed with standard containers during transportation, it is easy to cause the risk of damage to the container, which makes the circulation and transportation of this container subject to certain restrictions. Therefore, it is necessary to optimize its structure to overcome the above defects. Utility Model Content
[0003] The utility model aims to provide a container door frame structure with three locking rods to improve the structural strength thereof.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A container door frame structure with three locking rods comprises a door frame body, a door post is provided on the side of the door frame body, a door lintel is provided on the top of the door frame body, and further comprises:
[0006] The door frame reinforcement is installed in the door frame body, and the door frame reinforcement is used to structurally reinforce the door frame body. The installation position of the door frame reinforcement is located in the gap between the end door and the door frame body, and is close to the inside of the container, so as not to affect the opening and closing process of the end door.
[0007] In one embodiment of the present invention, the door frame reinforcement is installed at the upper left corner and the upper right corner of the door frame body.
[0008] In one embodiment of the present invention, one engaging surface of the door frame reinforcement is engaged with the lower surface of the door lintel, and the other engaging surface thereof is engaged with the side surface of the door column.
[0009] In one embodiment of the present invention, the cross section of the door frame reinforcement is L-shaped or triangular.
[0010] In one embodiment of the present invention, the door frame reinforcement is made of metal and is fixedly joined to the door frame body by welding.
[0011] The advantages of the utility model are:
[0012] The door frame structure can compensate for the reduced stacking capacity and rigid resistance due to the reduction in the number of locking rods on the container end doors by locally strengthening the door frame. After implementation on containers with three locking rods on the end doors, they can pass the relevant strength test requirements of standard containers and can also be used and transported like standard containers without restrictions.

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.
[0022] like Figure 3 to Figure 8As shown, the container door frame structure with three locking rods proposed by the utility model includes a door frame body, a door column 110 on the side of the door frame body, a door lintel 120 on the top, and a door frame reinforcement 200. The door frame reinforcement is installed in the door frame body, and the door frame body is structurally reinforced by the door frame reinforcement. The installation position of the door frame reinforcement is located in the gap between the end door and the door frame body, and is close to the inner side of the container, so as not to affect the opening and closing process of the end door.
[0023] In this embodiment, the door frame reinforcement is installed at the upper left corner and the upper right corner of the door frame body.
[0024] In this embodiment, one engaging surface of the door frame reinforcement member engages with the lower surface of the door lintel, and the other engaging surface thereof engages with the side surface of the door post.
[0025] In this embodiment, the cross section of the door frame reinforcement is L-shaped or triangular. Figure 6 , Figure 7 In the embodiment, the cross section of the door frame reinforcement is L-shaped. Figure 6 The door frame reinforcement is formed by bending the plate, and the thickness of the flanges on both sides is consistent. Figure 7 In the process, the door frame reinforcement is formed by rolling steel billets, the thickness of the flanges on both sides is gradually reduced, and a transition arc is formed at the connection between the flanges to improve its mechanical properties. Figure 8 In the embodiment, the cross section of the door frame reinforcement is a solid triangle, which has better stability.
[0026] In this embodiment, the door frame reinforcement is made of metal and is fixedly joined to the door frame body by welding.
