Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a bending door hinge for containers. Background Technique

[0002] At present, the bending door hinge installed on ordinary containers is a hinge installed through a clamping shaft installed inside the door frame. When the hinge rusts after long-term use, it will rub against the clamping shaft to generate certain noise and deformation. However, there are also some containers whose door frames do not have corresponding clamping shafts inside, so a new type of bending door hinge is needed that is convenient for maintenance, use and installation.

[0003] A bending door hinge for containers disclosed in the Chinese Utility Model Patent Application Publication Specification CN 219387589 U. This device improves the strength and stiffness of the bending door hinge without increasing the wall thickness of the product by adding reinforcing ribs at the easily deformed bending parts. However, the whole device is installed with the door body through a clamping shaft installed inside the container. After a long time, the hinge is prone to deformation, and when replacing, the internal clamping shaft needs to be taken out to remove the hinge, resulting in inconvenient use. Summary of the Invention

[0004] The purpose of the utility model is to provide a bending door hinge for containers to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
