Abstract

The invention discloses a life-saving baffle for fire doors, which comprises a door frame, a dust box, a handle, lock baffle life-saving troughs and a clamping chamber. A life-saving baffle is arranged inside the clamping chamber. The dust box is installed on the inside wall of the life-saving baffle. Fastening screws are arranged on the outer wall of the life-saving baffle on the two sides of thedust box. The lock baffle life-saving troughs are arranged on the side wall of the life-saving baffle at the positions of the fastening screws. A clamping piece is fixed to the outer wall of one endof the life-saving baffle. A rectangular clamping block is arranged in the center position of the inside wall of the clamping piece. A door leaf is arranged on one side of the door frame. A lock bodyis fixed to the outer wall of one side of the door leaf near the door frame. A lock body oblique tongue is arranged at one end of the lock body away from the door leaf. The stability of the life-saving baffle during installation and the convenience of installation of the life-saving baffle are improved, and the phenomenon of the life-saving baffle sliding out of and falling off from the life-saving trough is realized.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a lifesaving baffle for fire doors. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. When the fireproof lock on the door is exposed to fire and high-temperature barbecue, the lock body is deformed, the lock tongue and the lock block are stuck, and the lock body cannot be opened through the handle, so that the door leaf cannot be opened normally, which creates obstacles to rescue and escape; specially developed for this shortcoming The life-saving flap of the fire door can be hit by an external force on the lock body of the door leaf in the emergency state of rescue and escape, so that the life-saving flap is disconnected from the door frame, the life-saving flap falls off the door frame, and the lock tongue is released, and the door leaf is hit by ...
