Fire resisting roller shutter door with locking mechanisms

Abstract

The invention discloses a fireproof rolling door with a locking mechanism, which comprises a transmission mechanism, a reel, a track, a fireproof rolling door body, a socket and a locking mechanism, rails are arranged on both sides of the fireproof rolling door body, and the fireproof rolling door body The upper end is wound on the outer circumferential surface of the reel, and a transmission mechanism is fixed at one end of the reel. The fireproof rolling door body includes a small curtain surface, and a solid part is fixed in the middle of the lowermost one of the small curtain surfaces, and the lowermost end The inner two sides of a small curtain surface are all set as hollow parts, and there are two locking mechanisms in total. The present invention provides a locking mechanism, which can lock the fire-proof rolling door body on the track when the fire-proof rolling door body falls to the ground. On the one hand, it avoids the opening of the lower rolling door caused by the fire-proof rolling door body due to the negative pressure generated by the fire, so that the fire-proof rolling door can be tightly closed to block the fire.

Description

technical field [0001] The invention relates to the technical field of fireproof rolling shutters, in particular to a fireproof rolling shutter door with a locking mechanism. Background technique [0002] The fire shutter door refers to the shutter that can meet the fire resistance stability and integrity requirements together with the frame within a certain period of time. Walls that require fire separation, especially firewalls and fire separation walls that require large openings due to production and use but cannot be equipped with fire doors. However, the existing fire shutter doors do not have a locking mechanism. In the end, it is easy to open the lower part of the shutter door due to the negative pressure at the fire scene, so that the fireproof shutter door cannot play the role of fire prevention. Contents of the invention [0003] The object of the present invention is to provide a fireproof rolling door with a locking mechanism to solve the problems in the prio...
