Fireproof door for preventing fire from spreading
The invention discloses a fireproof door for preventing fire from spreading. The fireproof door comprises a door body. The door body is internally provided with a working space. An upper side slidingrail is arranged at the upper side of the working space. The rear side face of the upper side sliding rail is fixedly connected with the door body. An upper side door gap is formed in the upper side of the working space. A lower side door gap is formed in the lower side of the working space. According to the fireproof door, smoke prevention devices are designed for preventing dense smoke from flowing through the door gaps; an auxiliary door opening device is designed for guaranteeing that when the temperature of a door handle is excessively high, residents can smoothly open the door for escaping; and the switching-on sequence of mechanisms is set through the expansion velocity of an expansion block so that safety of indoor people can be guaranteed more reasonably in case of the fire.
本发明公开了一种防止火势扩散的防火门，包括门体，所述门体中设有工作空间，所述工作空间上侧设有上侧滑动轨道，所述上侧滑动轨道后侧面与所述门体固定连接，所述工作空间上侧设有上侧门缝，所述工作空间下侧设有下侧门缝，设计了防烟装置来阻止浓烟通过门缝流通，设计了辅助开门装置来保证门把手的温度过高时，住户也能顺利打开门逃生，利用膨胀块膨胀的速率来设定机构的开启顺序，以此来更为合理的安全的来保障室内人员在遇到火灾时的安全。
