Plugging device for cable protection pipe

Abstract

The invention discloses a plugging device for a cable protection pipe. A first pressing plate, a rubber sealing piece and a second pressing plate are arranged in sequence and can be pushed into the cable protection pipe in a matched manner, a passage for a cable to pass through is formed at the middle parts of the first pressing plate, the rubber sealing piece and the second pressing plate together, one end of a bolt passes through a through hole and a fourth opening of the second pressing plate in sequence to be in screw-thread fit with a nut from a third opening of the first pressing plate. According to the plugging device for the cable protection pipe through an optimal design, the structural design is optimal, the rubber sealing piece is clamped by the two pressing plates, one end of the bolt passes through the through hole from the first pressing plate to be matched with the nut on the side, away from the first pressing plate, of the second pressing plate, by means of force screwing the bolt and the nut, the inner wall clings to the outer wall of the cable after the rubber sealing piece is deformed, the outer wall clings to the inner wall of the cable protection pipe, the plugging effect for the end of the cable protection pipe is guaranteed, waterproof and moisture-proof effects are achieved, and simultaneously the position of the cable inside the cable protection pipe is fixed.

Description

technical field [0001] The invention relates to the technical field of cable installation, in particular to a cable protection pipe sealing device. Background technique [0002] When laying cables, it is necessary to set a cable protection tube outside the cables. On the one hand, it is convenient for cable laying, and on the other hand, it protects the cables from environmental influences and prevents rats and ants from eating. However, when the cable is laid in the cable protection tube, the environment wet liquid or corrosive substances are easy to enter the protection tube from the end of the protection tube, thereby directly contacting the cable sheath, affecting the protection effect on the cable. In addition, due to the dimensional difference between the inner diameter of the protective tube and the outer diameter of the cable, poor positioning of the cable in the protective sleeve results. Contents of the invention [0003] Based on the technical problems existing...
