Problems solved by technology

However, when the rubber body of the power pipe blocker is stressed at one end, the rubber body will continue to deform. When the rubber body deforms excessively, gaps will easily appear in the joint with the pipe wall, and the sealing function will be lost. Excessive deformation will damage the rubber body

Abstract

The invention discloses a pipe hole blocking device which is simple in structure, good in airtightness and not prone to damage. The pipe hole blocking device comprises an elastic material body, an upper sealing cover, a lower sealing cover, supporting frames and a connection piece. The elastic material body is in a straight cylinder shape. A hole penetrates the cylindrical body in the axial direction. An axial hole in the elastic material body is internally provided with the supporting frames matched with the hole, in other words, the shape of the supporting frames is the same as that of the axial hole of the elastic material body. The axial length of the elastic material body is longer than the length of the corresponding supporting frames in the same direction. The upper sealing cover and the lower sealing cover are arranged at the two ends of the elastic material body respectively. The upper sealing cover, the lower sealing cover, the elastic material body and the supporting frames are connected into a whole through the connection piece. The pipe hole blocking device has the beneficial effects of being simple in structure, reasonable in design, convenient to use and the like.
