Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a dust-free drag chain. Background Art

[0002] A drag chain is a device used to protect cables, air pipes and other wires. It usually consists of a series of interconnected links that can slide, fold or unfold during movement to form a movable channel to accommodate the cables or wires.

[0003] After searching, a Chinese patent with publication number CN207303962U discloses a dust-free drag chain, a drag chain line main body, and the drag chain line main body includes a clamping device, a load-bearing tube and a non-woven fabric. The clamping device has two groups, and the two groups of clamping devices are respectively fixedly installed at the two ends of the load-bearing tube. The load-bearing tube is located between the two groups of clamping devices, and the upper and lower sides of the section are respectively covered with non-woven fabrics. The clamping device includes an upper cover and a lower cover, and the upper cover and the lower cover are respectively clamped on the upper and lower sides of the load-bearing tube. An upper groove is provided on the inner side of the upper cover, and a lower groove is provided on the inner side of the lower cover. The upper cover and the lower cover are fixedly connected by fasteners.

[0004] When the above device is in use, the cable is passed through the carrier tube and the internal wiring harness is protected by the carrier tube. The problem is that the diameter of the wire hole inside the carrier tube is fixed. When the cable diameter is smaller than the diameter of the carrier tube, it is easy to affect the cable clamping stability and reduce the adaptability of the drag chain. For this reason, we propose a dust-free drag chain. Utility Model Content
