Referring to fig. 3, a return rubber ring 9 is sleeved on the top of the expansion rods 6 and below the top-support compression spring 4, and a limiting ring groove (not shown) for accommodating the return rubber ring 9 is formed in the air outlet pipe 2. When the outward expansion range of the sealing skirt 3 needs to be reduced, a worker screws the tightening ring 62 upwards, and the expansion rod 6 is contracted through the elastic force of the return rubber ring 9, so that the automatic tightening of the expansion rod 6 is realized. In the process of contraction of the expansion rod 6, the elastic sheet 7 and the top bracing ring are driven to move towards the direction of the adjusting groove 21 together, so that the top bracing force on the sealing skirt 3 is removed.
The specific implementation process comprises the following steps:
the staff screws up the shrink-ring 62 to be close to the rotating pin 61, and then establishes the intake pipe 121 on the outlet duct 2, and at the cover in-process, the inside wall of intake pipe 121 compresses tightly sealed shirt rim 3 for sealed shirt rim 3 contracts towards the center of outlet duct 2.
After being pressed by the air inlet pipe 121, the spring plate 7 and the top-supporting compression spring 4 urge the tip of the expansion lever 6 toward the inside of the adjustment groove 21, and at the same time, the tip of the expansion lever 6 moves out of the adjustment groove 21. At this time, the worker twists the tightening ring 62 to move it downward, and during the movement, the tightening ring 62 continuously tightens the expansion rod 6, and the top end of the expansion rod 6 moves out of the adjustment groove 21 according to the principle of lever.
The top end of the expansion rod 6 prompts the elastic sheet 7 and the top support compression spring 4 to tightly support the sealing skirt 3, and the sealing skirt 3 is tightly attached to the inner side wall of the air inlet pipe 121 by means of the elasticity of the elastic sheet 7 and the top support compression spring 4, so that the advantage of improving the sealing performance between the air inlet pipe 121 and the air outlet pipe 2 is achieved.
