Further, in order to make the large diameter section on the inspection tube keep a sealing state in the process of inserting the elastic opening, and can smoothly pass through, the elastic opening structure is as follows: a movable sealing ring is arranged on the inner wall of the lower end part of the inspection channel.
Further, in order to make the movable sealing ring be an elastic body and can be tightly attached to the inspection tube for movement, the structure of the sealing ring is as follows: the inner end is arc-shaped, the outer end is connected with a circular ring-shaped convex body of the wall body of the inspection channel, the circular ring-shaped convex body is provided with N breaking slits, and the upper surface and the lower surface of the connecting part are provided with a concave notch I and a concave notch II, so that the circular ring-shaped convex body is an arc-shaped split elastomer.
Further, in order to make the insertion of the inspection tube into the inspection channel take place without any gap, the aperture of the sealing ring is equal to or smaller than the diameter of the small diameter section of the inspection tube.
Further, in order to expand the elastic opening at the lower end of the inspection channel more expansively, an axial breaking slit which is correspondingly connected with N breaking slits on the movable sealing ring is arranged on the lower end wall part of the inspection channel, and the breaking slit wall body and the movable sealing ring (32-1) form an axial L-shaped split elastomer.
Further, in order to make the inspection tube be widely and more sealed when being inserted into the inspection channel for movement, the inspection channel is designed into a circular tube with a large upper opening and a small lower opening and is in a horn shape.
The beneficial effects of the invention are as follows: 1. because the elastic opening at the lower end of the inspection channel is designed into a movable sealing ring, and the movable sealing ring is an arc split type elastomer, when the arc elastomer is acted by the external force of the wall of the large-caliber inspection tube, the arc elastomer is opened, and the external force is closed after being lost, so that the movable sealing ring is tightly attached to the inspection tube, and the mask is ensured not to leak air; 2. the lower end wall part of the inspection channel is provided with an axial breaking seam which is correspondingly connected with the breaking seam of the movable sealing ring, so that the elastic opening at the end of the inspection channel has expansibility when being opened; 3. compared with the prior art, the invention has the advantages of wide applicability, applicability to inspection pipes with various caliber sizes, simple structure, convenient use and the like.
