TECHNICAL FIELD

[0001] The utility model relates to a drag chain technical field, concretely is a modularization drag chain of quick splicing. BACKGROUND

[0002] The drag chain is a device for protecting and managing pipelines such as electric wires, cables, oil pipes and gas pipes. It is usually composed of a series of chain links connected with each other, which can flexibly bend and stretch with the movement of the equipment during the operation of the equipment, so that the pipelines are well protected from damage such as abrasion, stretching and extrusion, and at the same time, the pipelines can be arranged in order, which is widely used in numerical control machine tools, automatic production lines, robots and other equipment and occasions requiring moving pipelines.
