Description

Technical Field

[0001] The utility model relates to a sealing structure, in particular to a detachable pipeline hole sealing device Background Art

[0002] When necessary, the wall or floor structure needs to be drilled to export or introduce the required pipelines, and due to the particularity of some walls (such as fire walls, civil air defense walls, etc.), the closure of the wall holes must be guaranteed. The traditional plugging structure generally chisels both ends of the drilled hole to form a conical expansion hole and then fills the plugging material to ensure the effective combination between the plugging material and the wall. However, on the one hand, the traditional plugging structure needs to use various auxiliary accessories such as baffles, pull rods, and sealing rings when filling the plugging material, which has poor integrity and is very troublesome to operate. In order to solve the problems existing in the prior art, the utility model with the technical disclosure number: CN219123906U discloses a cable pipe plugging mechanism (hereinafter referred to as: prior art 1), including a hollow tube, a rubber sealing sheet fixedly connected to the inside of the hollow tube, one end of the hollow tube fixedly connected to a rubber plug, and the other end of the hollow tube fixedly connected to a rubber plate, an injection hole is provided on the surface of the rubber plug, a card slot is provided on the surface of the injection hole, and a cross hole is provided on the surface of the rubber sealing sheet.

[0003] Although the prior art 1 can directly form a plugging cavity in one step without the need for the staff to adopt multiple steps to arrange the plugging structure; however, when the foam glue is poured into the cavity formed between the hollow tube and the cable tube, the foam glue is prone to generate bubbles, resulting in loose filling; and when the pipeline needs to be inspected or replaced, the plugging structure needs to be removed from the pipeline hole. After the pipeline hole is plugged with foam glue as a plugging material, the plugging structure cannot be quickly disassembled and assembled, which makes the maintenance of the pipeline difficult.

[0035] In the present invention, when sealing the pipeline hole, the pipeline is first placed in the sealing tube 101, and then the installation bevel 115 provided on the end of the arc plate 104 away from the sealing joint 103 is pushed into the pipeline hole. The installation bevel provided on the end of the arc plate away from the sealing joint is pushed into the pipeline hole so that the inner wall of the pipeline hole contacts the installation bevel, and the sealing tube enters the pipeline hole under the guidance of the installation bevel; in the process of pushing the sealing tube 101 into the pipeline hole, the outer surface of the arc plate 104 contacts the inner wall of the pipeline hole, and the first gas provided between the arc plate 104 and the sealing tube 101 is pressed. The airbag 106 is squeezed; the gas in the squeezed first airbag 106 enters the second airbag 107 through the air supply pipe 110, and the second airbag 107 is inflated to block the gap between the pipeline and the blocking tube 101; there are multiple arc plates 104 slidably installed on the blocking tube 101 through the moving rod 105, and after the multiple arc plates 104 are squeezed, each arc plate 104 moves toward the center of the blocking tube 101 until it contacts the adjacent arc plate 104, and the first airbag 106 and the arc plate 104 that have been squeezed and deformed together block the gap between the arc plate 104 and the pipeline hole.
