[0002] A container is a group of tools that can carry packaged or unpackaged goods for transportation and is easy to load, unload and handle with mechanical equipment. The bracket bushing assembly is the main component used on the door lock rod when the container door is opened. Its main function is to ensure that the lock rod can rotate freely after the bracket fixes the rod body.

[0003] The prior art authorization announcement patent document CN216995911U discloses a limiting bushing for a container lock rod bracket, wherein the edge protrusions of one end of the first bushing and the second bushing are provided with a skirt limiting structure, and the skirt limiting structure is in contact with the bracket, and plays a limiting role on the door lock rod bracket when the container door is opened. Compared with the bushing in the prior art that uses a stop flange as a limiting mechanism, the bushing of the utility model replaces the stop flange with a skirt limiting structure. When the limiting mechanism is subjected to the lateral shear force or external force collision of the lock rod, the skirt limiting structure has a larger force-bearing area and is not prone to damage or falling off, thereby improving the service life of the bushing and enhancing the limiting effect of the bushing on the bracket.
