Description

Technical Field

[0001] The utility model relates to a container, in particular to a bending-resistant container door post. Background Art

[0002] The end of the standard container is equipped with an end door, which is fixed to the door post by a hinge. The end door rotates around the door post to complete the door opening and closing operations. Its structure is as follows: Figure 1 , Figure 2 The door pillars of general containers are composed of an outer door pillar B1 made of cold-bent steel plates and an inner door pillar B2 made of hot-rolled channel steel. Figure 3 to Figure 5 As shown in the figure, the strength of this combined door post can meet the requirements of opening and closing doors by rotating in general containers. However, for some special containers, the door panels are relatively thick, or the door panels and end frames need to rotate around the door posts. When the door panels rotate around the door posts, the bending force on the door posts will also increase a lot. If the combined door post structure of ordinary containers is still used, the door panels will fall due to excessive deformation of the door posts, causing damage to the container. Therefore, it is necessary to optimize the structure of the door posts of this container to overcome the above defects. Utility Model Content

[0003] The utility model aims to provide a bending-resistant container door post to improve the structural strength of the container door post.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A bending-resistant container door post, comprising:

[0006] An inner column assembly, the inner column assembly is formed by enclosing metal plates;

[0007] The outer column assembly is formed by bending a metal sheet, the inner column assembly is joined to the inside of the outer column assembly, the inner column assembly supports the outer column assembly, and the outer column assembly covers the inner column assembly.

[0008] Specifically, the inner column assembly is a long strip structure, which is formed by enclosing a group of rectangular steel plates and has a rectangular cross-section.

[0009] In one embodiment of the present invention, adjacent rectangular steel plates are fixedly connected by welding.

[0010] In one embodiment of the utility model, welding grooves are respectively opened at the edges of each rectangular steel plate, and solder is filled in the welding grooves to join adjacent rectangular steel plates to each other and to ensure a stable joint between adjacent rectangular steel plates.

[0011] In one embodiment of the utility model, the outer column assembly is a long strip structure, which is formed by cold bending of rectangular steel plates.

[0012] In one embodiment of the present invention, the inner column assembly is fitted to the inner wall of the outer column assembly and is fixedly connected to the outer column assembly by welding.

[0013] In one embodiment of the utility model, the thickness of the metal plate used in the inner column assembly is greater than the thickness of the metal plate used in the outer column assembly, so that the inner column assembly plays a supporting role and the outer column assembly plays a shielding role, which can effectively resist the bending force of the heavy door panel on the door column and meet the normal use of the container with heavy door panels.

[0014] The advantages of the utility model are:

[0015] The inner column assembly of the container door column is formed by enclosing thicker rectangular steel plates, and its cross-section is rectangular. Such a structure enables the inner column assembly to have a strong supporting capacity and be able to resist the bending force applied by the end door to ensure that the door column does not bend or deform. The outer column assembly is formed by cold bending of rectangular steel plates, which can not only provide additional protection for the inner column assembly, but also cover the inner column assembly, so that the entire door column has a neat and beautiful appearance. The inner column assembly and the outer column assembly are fixedly connected by welding, so that the two are tightly combined to form a whole, thereby enhancing the stability of the door column. The welding grooves opened on the edges of each rectangular steel plate further ensure the stable connection between adjacent steel plates, so that the door column has strong bending resistance and stability, can ensure the normal opening and closing and safe use of the container end door, and reduce the safety hazards caused by deformation or damage of the door column.

[0024] 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.

[0025] like Figure 6 , Figure 7 As shown, the bending-resistant container door column proposed by the utility model includes an inner column assembly 100 and an outer column assembly 200. The inner column assembly is formed by enclosing metal plates, and the outer column assembly is formed by bending metal plates. The inner column assembly is joined to the inside of the outer column assembly, and the inner column assembly supports the outer column assembly, and the outer column assembly covers the inner column assembly.

[0026] In this embodiment, the inner column assembly is a long strip structure, which is formed by enclosing a group of rectangular steel plates and has a rectangular cross-section.

[0027] In this embodiment, adjacent rectangular steel plates are fixedly connected by welding.

[0028] In this embodiment, welding grooves 210 are respectively opened at the edges of each rectangular steel plate, and solder is filled in the welding grooves to join adjacent rectangular steel plates together and ensure that the adjacent rectangular steel plates are firmly joined.

[0029] In this embodiment, the outer column assembly is a long strip structure, which is formed by cold bending of rectangular steel plates.

[0030] In this embodiment, the inner column assembly is attached to the inner wall of the outer column assembly and is fixedly connected to the outer column assembly by welding.

[0031] In this embodiment, the thickness of the metal plate used in the inner column assembly is greater than the thickness of the metal plate used in the outer column assembly, so that the inner column assembly plays a supporting role and the outer column assembly plays a shielding role.

[0032] The typical application status of this kind of door column in the container is as follows Figure 8As shown in the figure, the end door 320 with a square tube door frame 310, together with the hinge 330, the inner column assembly 100 and the outer column assembly 200, is relatively heavy as a whole, and its weight is much heavier than a single door panel. When they rotate together around the hinge 400 respectively welded on the outer column 430 and the outer column 200 of the end frame, since such a door column has sufficient strength and rigidity, it can ensure that the end door with the square tube door frame and the door frame including the door column will not be deformed and damaged when they rotate together as a whole. The square tube door frame is also provided with a sealing strip 340 adapted to the inner column assembly to seal the gap between the square tube door frame and the inner column assembly. The inner column is also provided with a rubber strip 350 which is sealed by extrusion with the bending part 410 on the inner column 420 of the box end frame.
