AI Technical Summary
The existing fireproof and impact-resistant sealing strips are not securely fixed by the ribs, causing the sealing strips to loosen in the installation groove and easily fall off, thus failing to effectively protect against the entry of flames and toxic fumes.
The design employs a sliding block and friction pad. The sliding block drives the abutment and friction pad to slide, increasing friction. Combined with the structure of the spring and limit frame, this ensures that the sealing strip is stable in the mounting groove, enhancing the fixing effect.
It improves the installation stability and sealing performance of the sealing strip, prevents it from falling off, enhances its practicality in fire prevention and impact protection, reduces door closing noise, and improves the protective effect.
