Combined fire resisting shutter linkage release system

Abstract

The invention provides a combined fire resisting shutter linkage release system. The combined fire resisting shutter linkage release system comprises a plurality of fuses, a plurality of door closers and a remote actuator. Each fuse has a compression energy storage state and an extension release state; each door closer is used for correspondingly triggering a brake release rod of each single door rolling machine, each door closer is provided with a core-pulling stay wire, and each core-pulling stay wire is correspondingly connected with each fuse; the remote actuator is provided with a tension stay wire used for connecting the fuses in series, and the remote actuator has a locking state for tightening the tension stay wire and an unlocking state for loosening the tension stay wire; and when the remote actuator is switched to be in an unlocking state and / or at least one fuse is fused, each fuse is switched to be in a stretching release state and triggers the door closer to act through the core-pulling stay wire. According to the combined fire resisting shutter linkage release system, the timeliness of self-closing response of the combined fire resisting shutter by means of self weight can be improved.
