Abstract
The utility model relates to a combination gasket and a bolt sealing structure. The combination gasket comprises a rigid flat gasket. The flat gasket is provided with a cylindrical through hole. The flat gasket is provided with a counter bore coaxial with the through hole. One end of the counter bore is connected with the cylindrical through hole. The inside of the counter bore is provided with a ring-shaped flexible sealing gasket. The counter bore is a cone-shaped hole. The small-diameter end of the cone-shaped hole is connected with the cylindrical through hole on the flat gasket. When the combination gasket is not extruded, the axial thickness of the flexible sealing gasket arranged in the cone-shaped counter bore is greater than the depth of the cone-shaped counter bore. The combination gasket is arranged between a bolt and a bolt fixing piece to form the bolt sealing structure so as to strengthen the sealing and waterproof effects of a bolt structure.
