Non-welded plastic-coated steel protective cable chain

The utility model provides a non-welded plastic-coated steel protective cable chain, which comprises at least two chain buckles, wherein a metal framework is arranged on each chain buckle, the metal frameworks are oval, a through hole is formed on the side surface in the direction of a long shaft of each oval metal framework, a molding layer is coated on the periphery of each metal framework, a molding block is filled in each through hole, the length L of the through hole is larger than the diameters D2 of the metal frameworks and the molding layers, and the molding layers and the molding blocks are made of the same material. The non-welded plastic-coated steel protective cable chain can solve the deficiencies in the prior art and greatly improve the production efficiency under the premise of leading the tensile strength and the compressive strength to be same with those of the cabin chain in the prior art basically.
