Fire control curtain for overcoming defects of normally-closed fireproof door
The invention relates to the technical field of fireproof doors, in particular to a fire control curtain capable of overcoming the defects of a normally-closed fireproof door, which comprises a roller shutter mechanism capable of placing a roller shutter, a guide rail mechanism arranged below the roller shutter mechanism and capable of enabling the roller shutter to move downwards, and a limiting mechanism mounted in the guide rail mechanism. Through high temperature generated in fire, a first limiting plate and a second limiting plate can be softened and melted, a roller shutter moves downwards under the action of gravity of a first weight block and a second weight block, automatic closing of the fireproof door is achieved, the protective door is in a normally-open state, people can escape conveniently, and the fireproof door is safe and reliable. A first rotating gear is connected with a first chain assembly in a meshed mode, a second rotating gear is connected with a second chain assembly in a meshed mode, transmission and resistance between the gears and the chain assemblies can be utilized, the roller shutter can slowly move downwards under the action of the gravity of a weight block, and the roller shutter is prevented from falling down rapidly and being damaged; and the smoke and fire blocking effect is influenced.
本发明涉及防火门技术领域，特别涉及一种解决常闭防火门缺陷的控火帘，包括：可对卷帘进行放置的卷帘机构，卷帘机构的下方设有可使卷帘进行向下移动的导轨机构，导轨机构的内部安装有限位机构，当火灾发生时，通过火灾时产生的高温，可使第一限位板与第二限位板变软融化，使卷帘在第一重物块与第二重物块的重力的作用下，向下运动，实现了防火门的自动闭合，并且防护门处于常开的状态，便于人员进行逃生，通过第一转动齿轮啮合连接第一链条组件，所述第二转动齿轮啮合连接第二链条组件，可利用齿轮与链条组件的之间的传动以及阻力，使卷帘在重物块重力的作用下，可以缓慢的向下运动，防止卷帘快速落下，造成卷帘的损坏，影响对烟火的阻隔效果。
