▎ 摘　　要

NOVELTY - The conduit has a first reinforcement layer fixedly connected on inner wall of a pipeline main body. The first reinforcement layer is fixedly connected with a second reinforcing layer. An end of the pipeline main body is provided with a connecting mechanism that includes a connecting seat (23). Upper and lower ends of a front side of the pipeline main body are fixedly connected with a first connecting sleeve (24). A connection assembly and a snap-fit assembly are arranged between an insert block (25) and an inner wall of a slot (30). The first reinforcing layer is made of graphene of a thin film material. The second reinforcing layer is made of aluminium oxide material. A skid-proof sleeve (46) is made of rubber material. USE - Impact-resistant modified polypropylene cable conduit for protecting a cable in a pipeline. ADVANTAGE - The conduit realizes function of enhancing the overall impact resistance of the pipeline through structural design of the first strengthening layer and the second strengthening layer. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged view of an impact-resistant modified polypropylene cable conduit. 23Connecting seat 24First connecting sleeve 25Insert block 26Connection cavity 27Casting iron sheet 28Magnetic sheet 29Block 30,31Slots 32Sleeve groove 33Sleeve block 34Movable cavity 35Slider 36Chute 37Containing cavity 38Second connecting sleeve 39Screw 41Driven gear 42Driving gear 43Transmission cavity 45Knob 46Skid-proof sleeve 49Limit block 51Limit groove 56Fixing cavity 57Fixing spring 58Fixing block 59Fixing groove 61Moving block 62Moving groove
