[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a wedge ring compression expandable pipeline occluder, comprising a plurality of wedge ring occluders 1, the wedge ring occluders 1 being evenly distributed in a straight line, the wedge ring occluders 1 being provided with a plurality of through holes penetrating the wedge ring occluders 1, the through holes being provided with pipes 2, the pipes 2 between adjacent wedge ring occluders 1 being set in abutment with each other, the wedge ring occluders 1 on the left side being removed, the remaining wedge ring occluders 1 being provided with a first connecting ring 5 at one end, and a second connecting ring 6 at the other end, the adjacent pipes 2 being pressed and positioned by the first connecting ring 5 and the second connecting ring 6, the interior of the pipes 2 being provided with push rods 8, the adjacent push rods 8 being set in contact with each other, one end of the push rods 8 being protruded to form an extrusion portion 7, and the extrusion portion 7 being set in abutment with one end face of the wedge ring occluder 1.

[0021] In this embodiment, a nut 3 is threadedly connected to the wedge ring occluder 1 on one side, and an annular groove 12 is provided on the inner side surface of the nut 3. A strip opening communicating with the outside is provided on the outer wall surface of the pipe 2. One end of the extrusion portion 7 is arranged through the strip opening, and the extrusion portion 7 on one side is inserted into the annular groove 12. A positioning ring 9 is installed on the end of the pipe 2 away from the extrusion portion 7, and one side surface of the positioning ring 9 is in conflict with the other end face of the wedge ring occluder 1.

[0022] In this embodiment, pressure rings 4 are installed at both ends of the pipe 2. Adjacent pressure rings 4 are arranged in close contact with each other, and the close contact pressure rings 4 are compressed and fixed by the first connecting ring 5 and the second connecting ring 6.

[0023] In this embodiment, the outer ring surface of the first connecting ring 5 is recessed inward to form a connecting groove 10 with an annular structure, and the outer ring surface of the connecting groove 10 is provided with an internal thread. One end face of the second connecting ring 6 protrudes to form a connecting portion 11 with an annular structure, and the inner ring surface of the connecting portion 11 is provided with an external thread. The connecting portion 11 is sleeved in the connecting groove 10 and is engaged with the internal thread on the connecting groove 10 through the external thread. The threaded connection facilitates subsequent disassembly, so that the wedge ring occluders can be quickly separated.

[0024] In this embodiment, the outer ring surface of the push rod 8 is arranged in contact with the inner side surface of the pipe 2, which increases the sealing between the push rod and the pipe.
