Description

Technical Field

[0001] The utility model relates to the technical field of containers, in particular to a door hinge for containers which is easy to replace. Background Art

[0002] A container is a stackable metal box used for transporting and storing goods. The main advantage of containers is that they can be easily transferred between different modes of transport. The doors of containers are usually connected by hinges, which are located on the sides of the container, so that the goods can be easily loaded and unloaded. When loading and unloading existing containers, their hinges are inevitably collided, resulting in damage to the hinges. Generally, the hinges of container doors are all integrated, and the entire hinge needs to be replaced, which is not only costly and causes great waste, but also the entire replacement process is quite troublesome, and the hinge needs to be removed from the door and the box at the same time. Therefore, the present invention proposes a container door hinge that is easy to replace to solve the problems mentioned in the above background technology. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A door hinge for a container that is easy to replace comprises a fixed part, a rotating part is arranged in front of the fixed part, a sliding sleeve seat is fixed to the front side of the fixed part, a bearing sleeve is arranged in the sliding sleeve seat, a rotating shaft is arranged in the bearing sleeve, a connecting buckle block is fixed to the upper end of the rotating shaft, and a supporting bottom plate is fixed to the lower end of the rotating shaft, a plurality of bolts are arranged between the upper part of the rotating part and the corresponding connecting buckle blocks, a plurality of fixing studs are fixed on the upper side of the supporting bottom plate, and a plurality of insertion holes corresponding to the fixing studs are opened at the lower part of the rotating part.

[0006] Preferably, a limiting slider is fixed on the outside of the bearing sleeve, and a corresponding sliding groove is provided in the sliding sleeve seat, and the bearing sleeve and the internal rotating shaft slide up and down in the sliding sleeve seat.

[0007] Preferably, a limiting block is fixed to the lower end of the bearing sleeve, and a compression spring is arranged between the upper side of the limiting block and the sliding sleeve seat.

[0008] Preferably, a locking nut is provided on the fixing stud and is closely attached to the lower side of the rotating part.

[0009] Preferably, a plurality of openings corresponding to the bolts are provided on the upper portion of the rotating portion, and a plurality of screw holes corresponding to the openings are provided on the connecting buckle block.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model aims at the fact that the damaged part of the existing door hinge is generally the rotating part, so the traditional hinge is disassembled and designed to be two detachable parts, a fixed part and a rotating part. The fixed part is fixed on the box body, and the rotating part is fixed on the door. The rotating part can be conveniently and quickly combined and connected with the rotating part and fixed to the door hinge. In the process of disassembly and replacement, it is only necessary to replace the rotating part on one side. The connection structure between the rotating part and the fixed part of this structure is not only high in strength, but also can be disassembled and assembled, which greatly saves the investment cost of hinge replacement and facilitates the replacement of damaged door hinges, thereby achieving the purpose of reducing costs and increasing efficiency.
