    • A device for at least partially blocking an opening includes a first body, a second body rotatably mounted to the first body and a compressible seal extending from the first body. The seal includes a first portion, a plate having a hole at one end of the first portion, and a second portion extending away from the plate. A hollow shaft extends from the second body and through the first body, the first portion, the hole in the plate, and into the second portion. The shaft has a shoulder in the second portion that is wider than the hole in the plate, and moving the shaft relative to the first body compresses the second body until the shoulder reaches the plate and then compresses the first body. Such compression expands the first and/or second portions and presses them against the inside of the opening to form a seal.
    • 用于至少部分地阻挡开口的装置包括第一主体,可旋转地安装到第一主体的第二主体和从第一主体延伸的可压缩密封件。 密封件包括第一部分,在第一部分的一端具有孔的板以及远离板延伸的第二部分。 空心轴从第二主体延伸并且穿过第一主体,第一部分,板中的孔,并进入第二部分。 轴在第二部分具有比板中的孔宽的肩部,并且相对于第一主体移动轴压缩第二主体,直到肩部到达板,然后压缩第一主体。 这种压缩使第一和/或第二部分膨胀,并将其压靠在开口的内部以形成密封。
