The chain plates, pins, and large tubes are treated with nickel plating, significantly improving the corrosion resistance of the chain. It can extend the service life in harsh environments. In addition, the nickel plating layer can also improve the wear resistance of the chain, reduce friction and wear, and keep the chain running smoothly. The lightweight chain using nickel plating can effectively improve the use effect of the chain.

[0003] In the prior art during use, the existing chain structure usually directly opens a chute for the buckle in the connection area. When installing and disassembling, it needs to be deformed to a certain extent by extrusion, resulting in frequent replacement of the buckle structure in the connection area, increasing the maintenance cost. At the same time, directly opening a chute on the connected chain plate will reduce the strength of the chain plate. Summary of the Utility Model

When installing and disassembling, it needs to be deformed to a certain extent by extrusion, resulting in frequent replacement of the buckle structure in the connection area, increasing the maintenance cost. At the same time, directly opening a chute on the connected chain plate will reduce the strength of the chain plate. By setting a connection component, the replacement cost can be reduced.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A lightweight anti-rust chain, including inner chain plates, a disassembly component is embedded in the middle of the inner chain plates, and the disassembly component is used for flexible disassembly and recycling. A connection component is arranged on the outer side of one end of the inner chain plates, and the connection component is used to reduce the replacement structure and lower the cost;

[0015] 1. By installing a connection component, the utility model can pass the limiting column through the inner link plate, combine the limiting plate with the inner link plate, and then limit the movable groove and buckling groove of the limiting piece through the column groove. When disassembling, directly push the limiting piece to move to disassemble the limiting piece, and then remove the limiting plate in turn. Avoiding directly opening holes in the limiting plate can avoid weakening the strength. At the same time, the outer limiting piece is thinner, and replacement can reduce the cost to a certain extent.

[0016] 2. By installing a disassembly component, in the existing chain structure, when disassembling and replacing, the middle sleeve structure usually needs to be replaced synchronously, and a professional tool is required to push out during disassembly, which is not convenient for users to manually replace and repair. By providing a sleeve, it can limit the combined screw sleeve at the right end. After inserting the sleeve, rotate the combined screw sleeve and install it inside, and then use two limiting discs to limit the inner structure.
