This utility model belongs to the field of
gasket technology, specifically disclosing a self-tightening sealing
gasket with adjustable thickness. The utility model includes a first
gasket body and a second gasket body, with a thickness adjustment
assembly between them. The thickness adjustment
assembly includes a stacking unit and a fixing unit. The stacking unit includes an adjusting piece, which adjusts the thickness by stacking. The thickness adjustment
assembly allows for flexible thickness adjustment by increasing or decreasing the number of adjusting pieces, adapting to the installation gaps of different devices. Furthermore, the corresponding
insertion structure of the limiting block and the corresponding
insertion hole / slot, along with locking bolts, securely fixes the first gasket body, the second gasket body, and the adjusting piece. This ensures both thickness adjustment and overall
structural stability, preventing displacement or loosening of the adjusting piece under pressure or vibration, thus maintaining the gasket's
mechanical strength and sealing performance.
