Opening and closing assisting mechanism of fireproof door
The invention relates to the technical field of fire fighting, and discloses an opening and closing assisting mechanism of a fireproof door. The opening and closing assisting mechanism comprises a door body; handles are movably installed on the two sides of the door body; a liquid storage cavity is formed in the lower end of an inner cavity of the door body; an inner cavity of the liquid storage cavity is filled with evaporated liquid; and a rectangular movable cavity is formed in the outer side of the inner cavity of the door body. By arranging an automatic closing assisting mechanism, when a fire occurs, the fireproof door is automatically closed under the action of a fireproof door closer; and when the fireproof door cannot be automatically closed due to the fact that a hinge of the fireproof door is rusted or the door body is blocked by foreign matter, the evaporated liquid in the liquid storage cavity is rapidly vaporized under the action of the relatively high temperature of a fire scene and flows into the movable cavity through a liquid flowing groove, and gas filling in the movable cavity is gradually increased, so that the impact force of gas blown outwards from a gas blowing hole is gradually increased, the force generated when the door body is closed is gradually increased under the action of gas counter-acting force, and then the fireproof door is closed by overcoming resistance generated abnormally.
本发明涉及消防技术领域，且公开了一种防火门的启闭助力机构，包括门体，所述门体的两侧活动安装有把手，所述门体内腔的下端开设有储液腔，且储液腔的内腔填充有蒸发液，所述门体内腔的外侧开设有呈长方形的活动腔。本发明通过设置自闭助力机构，使得当火灾发生，防火门在防火闭门器的作用下自动闭门，而防火门的铰链生锈或门体处有异物抵挡，导致防火门无法自动关闭时，储液腔内的蒸发液在火灾现场较高温度的作用下快速汽化，并通过通液槽向活动腔内流通，并使活动腔内气体填充逐渐增多，从而使得吹气孔处向外吹出的气体冲击力逐渐增加，从而在气体反作用力的作用下，使门体关闭时的力逐渐增加，进而将克服异常产生的阻力将防火门关闭。
