As shown in fig. 1, when the sealing device provided by the embodiment of the present invention is used as a part of a door lock, it is necessary to avoid some structures of the door lock itself, and therefore, the rotating plate 7 extends to the right to a position opposite to the outer side and is hinged to the first link 1, the first link 1 extends downward and is hinged to the second link 2, the second link 2 extends to the left and is connected to the third link 3, and the second link 2 is a lever, so that the upward and downward movement of the first link 1 is changed to the upward and downward movement of the third link 3. Preferably, when the rotating device is in the initial position, the first link 1 is perpendicular to the second link 2, the second link 2 is perpendicular to the third link 3, and the first link 1 is parallel to the third link 3.
In order to ensure that the projection 5 does not carry the fourth link 4 to move when the rotating device is reset, the height of the groove 6 is not less than the height of the projection 5 moved by the rotating device when the rotating device returns to the initial position from the position of pushing the fourth link 4 to move. Optimally, these two heights are equal, for example, when the rotating device is in the initial position, the protrusion 5 is attached to the lower wall surface of the groove 6, as shown in fig. 1; rotating the rotating device, the projection 5 moves downwards to push the sealing element 13 to complete sealing, as shown in fig. 2; the rotating device is released to reset, and the protrusion 5 moves upwards to be attached to the upper wall surface of the groove 6, as shown in figure 3; then the rotating device is rotated reversely, the bulge 5 moves upwards to push the sealing piece 13 to remove the sealing, as shown in figure 4; the rotating device is released to reset, and the protrusion 5 moves downwards to be attached to the lower wall surface of the groove 6, as shown in fig. 5; one cycle is completed.
In order to limit the rotation angle of the rotating device, a limit hole 8 is provided on the rotating plate 7, and a limit rod 9 for limiting the rotation angle of the rotating plate 7 is provided in the limit hole 8. For example, the stopper hole 8 has a curvature, and when the rotary plate 7 rotates, the stopper hole 8 rotates to a certain angle and is blocked by the stopper rod 9. Wherein, a return spring 10 is arranged on the rotating plate 7, so that the rotating device can automatically return.
