A novel cable duct plugging device

Abstract

The invention discloses a novel cable duct plugging device, including a rubber cylinder, one side of the cylinder is provided with an opening along the height direction thereof, the diameter of the outer wall of the cylinder gradually increases from both ends to the middle, the diameter of the inner wall of the cylinder decreases gradually from both ends to the middle, an upper pressure plate is arranged at the upper end of the cylinder, a lower pressure plate is arranged at the lower end of the cylinder, the upper pressure plate, the lower pressure plate and the cylinder are provided with longitudinally correspond through holes, a screw passes through the lower pressure plate, the cylinder and the through holes of the upper pressure plate in turn from bottom to top, nuts of the screw arearranged at the lower end of the plugging device, and nuts are arranged at the upper end of the screw passing through the upper pressure plate. The plugging device squeezes the cylinder between the upper and lower pressure plates through bolts and nuts so that the inner wall of the plugging device protrudes inwardly, and the plugging device is in close contact with the cable; the outer wall protrudes outward and clings to the wall of the cable pipe, and the middle part of the inner wall and the outer wall of the cylinder is provided with a protrusion, so that the plugging effect is better, looseness is prevented, the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of pipeline fittings, in particular to a novel cable duct sealing device. Background technique [0002] The pipe blocker is a sealing device installed in the cable pipe, which can prevent the water, sediment, and animals from moving and damaging the cable. The end face between the pipe and the cable, or fill the end of the pipe where no cable passes through, so as to fix the cable and realize the sealing of the pipe, but the sealing effect of the existing pipe occluder is poor, and it is easy to loosen after a long time of use . Contents of the invention [0003] In view of this, the object of the present invention is to provide a novel cable duct occluder, which has a good sealing effect, is not easy to loosen, has a simple structure and is easy to use. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The new cable duct blocker includes a cyl...
