Dynamic sealing device of steel wire rope

The invention provides a dynamic sealing device for a steel wire rope, and relates to the technical field of dynamic sealing. A first guide sleeve, a first packing layer, an adjusting assembly, a second packing layer and a second guide sleeve are sequentially arranged in the first mounting hole, the first guide sleeve is used for limiting the position of the end of the first packing layer, and the second guide sleeve is used for limiting the position of the end of the second packing layer; the first filler layer and the second filler layer wrap the outer side of the steel wire rope, the adjusting assembly is used for extruding the first filler layer and the second filler layer so that the first filler layer and the second filler layer can deform and be attached to the outer surface of the steel wire rope for sealing, and therefore the strength of the first filler layer and the second filler layer for tightly holding the steel wire rope can be adjusted; and the rotating torque can be effectively released. 本申请提
