At this time, the gravity of the falling bracket 203 itself can drive the fireproof cloth 206 to be pulled. At this time, the fireproof cloth 206 It also drives the winding reel 205 to rotate inside the shell cover 204, and at the same time the falling bracket 203 slides on the surface of the L-shaped limit plate 202 on the card strip 201 through the opened sliding groove until the falling bracket 203 falls to the bottom of the corridor wall 1, thereby blocking the open part of the corridor wall 1 through the fireproof cloth 206. Through this operation, the open part of the corridor wall 1 is completely closed, and the open flame inside the building is blocked by the fireproof cloth 206 and cannot continue to spread, thereby controlling the burning area of the fire and reducing economic losses. This barrier fire extinguishing effect is better, improving the use effect of the device and meeting actual use needs.
