A rubber sealing strip

ActiveCN224283445UInhibit sheddingAchieving tightnessEngine sealsMechanical engineeringPhysics
This utility model discloses a rubber sealing strip in the field of sealing strips, including an integrally molded sealing body. One end of the sealing body extends outward to form a bent portion, which extends along the length direction of the sealing body. Another end of the sealing body extends outward to form a fixing portion, which extends along the length direction of the sealing body. One end of the bent portion extends outward to form a connecting portion, which extends along the length direction of the sealing body. One end of the fixing portion extends outward to form a positioning portion, which extends along the length direction of the sealing body. This utility model's rubber sealing strip achieves the dual functions of multi-level sealing and mechanical engagement through the engaging groove, sealing groove, and fixing groove formed by the bent portion, fixing portion, and sealing body. The engaging groove can precisely fit with the installation part to prevent the sealing strip from falling off. The sealing groove and fixing groove fill the gap through elastic deformation, improving the sealing performance.
