Embodiment 1

[0014] Embodiment one: see attached figure 1 to attach image 3 As shown, a cable conduit plug for sealing cable conduits includes a ceramic body 1 , and the ceramic body 1 includes a cylindrical outer edge portion 2 and a frustum-shaped insertion portion 3 . The plug-in part 3 is coaxial with the outer edge part 2, and its axis is also the axis of the pipe it blocks.

[0015] The outer edge part 2 has two circular end surfaces with equal areas, and the plug-in part 3 has two circular bottom surfaces, but the two areas are not equal, one is larger and the other is smaller. The larger bottom surface of the insertion part 3 is coplanarly connected to one end surface of the outer edge part 2 , and the area of ​​the larger bottom surface of the insertion part 3 is still smaller than the area of ​​the end surface of the outer edge part 2 . The insertion part 3 also has a side inclined relative to its bottom surface, and a sealing gasket (not shown in the figure) is provided on th...

Abstract

The invention relates to a cable tube bank plug. The cable tube bank plug comprises a ceramic body, wherein the ceramic body comprises a cylindrical outer edge part and a circular-truncated-cone-shaped plugging part, wherein the large-area bottom surface of the plugging part is connected to one end face of the outer edge part in a coplanar manner and the plugging part is coaxial to the outer edge part; the area of the large-area bottom surface of the plugging part is smaller than that of the end face of the outer edge part; the outer edge part and the plugging part are provided with a penetrating hole along the axis of the outer edge part and the plugging part; an end cover plate for blocking the cross section of the penetrating hole is arranged inside the penetrating hole; a stressed raised strip protruding along the axial direction of the outer edge part and surrounding the penetrating hole is arranged on the other end face of the outer edge part; the outer circumference of the stressed raised strip corresponds to that of the large-area bottom surface of the plugging part; a sealing gasket is arranged on the oblique side surface of the plugging part. The cable tube bank plug disclosed by the invention can be used for closely blocking the end opening of a tube bank, has certain strength by being provided with the stressed raised strip and made from a ceramic material, and can be crushed conveniently so as to be conveniently dismounted during dismounting.

Description

technical field [0001] The invention relates to a pipeline sealing device, in particular to a pipe plug used for sealing the end of cable pipes in cable channel engineering. Background technique [0002] In the prior art, rubber plugs are usually used for plugging the end of the pipe arrangement of the cable channel project. The elastic rubber plug is nested into the end of the pipe, so that the outer peripheral surface fits the inner surface of the pipe, so that the cable pipe is simply blocked. However, due to the properties of the rubber itself, the rubber stopper cannot closely fit the inner wall of the exhaust pipe, and there are problems such as easy to fall off during use, difficult to remove when it needs to be removed, and easy aging of the material. Contents of the invention [0003] The purpose of the present invention is to provide a cable pipe plug that can be closely attached to the pipe without falling off and is easy to assemble and disassemble. [0004] ...
