Air inside the airbag ring is drawn into the inner cavity through the connecting hole, and the volume of the airbag ring decreases. Then, the connecting pipe is connected to the pipe with bolts. Then, the clamping plate is rotated, and the elasticity of the elastic plate causes the connecting post to be inserted into the slot. When the connecting pipe and the pipe become loose, the clamping plate will drive the pull plate to move closer to the pipe, causing the movable rod to slide the sealing ring inside the inner cavity. Air inside the inner cavity is introduced into the airbag ring through the connecting hole, causing the airbag ring to expand and seal the gap between the pipe and the connecting pipe caused by loosening. By setting up a leak-proof device, when a gap appears between the pipe and the connecting pipe due to loosening, the expanded airbag ring can be used to seal it, thus preventing water leakage and effectively improving the sealing performance of the equipment.
