The utility model discloses a kind of fireproof
doors of strong
impact resistance protection, including door frame, and the inside hinged of door frame has two groups of fireproof door body, fixed seat, fixedly installed in the top of door frame, for realizing the cooling
protection mechanism of the cooling protection of the two sides of fireproof door body, and cooling
protection mechanism is arranged in the inside of fixed seat, the cooling
protection mechanism includes spraying subassembly and air extraction subassembly, the utility model is synergized by door frame, two groups of hinged fireproof door body, fixed seat and cooling protection mechanism, the stable structure formed by the hinging of two groups of fireproof door body and door frame provides reliable
impact resistance basic performance for whole, in cooling protection mechanism, spraying subassembly can directly
spray cooling to the two sides of fireproof door body, air extraction subassembly can then assist extraction door body periphery's high-temperature
flue gas, the temperature rise problem of door panel caused by the long-time
erosion of both cooperation effective
flame,
delay the damage speed of fireproof door body.
