The utility model relates to a foldable double-layer refuge frame device for escape after a disaster, which belongs to the refuge device. It includes an internal flexible mechanism, an external flexible mechanism, a connecting mechanism and a perception system. The internal foldable mechanism includes an inner layer rotating rod, a pulley on the inner layer rotating rod, and an inner layer bracket. The internal foldable mechanism is connected with the four brackets respectively by the rotating rod to form a space cube, which can be folded and unfolded through the external motor and the rope. The connecting mechanism is composed of a ball auxiliary shaft and a connecting rod, which can realize the implicated movement of the inner and outer layers. The structure of the external folding mechanism is the same as that of the internal folding mechanism, and the external folding mechanism and the internal folding mechanism are connected by a connecting mechanism to realize synchronous folding under the traction of the rope. The sensing system includes various types of sensors. Under normal circumstances, the device is in a folded state to minimize the occupied space. When a disaster occurs, it is unfolded. There is a certain space inside the system, which can accommodate people as a temporary shelter.
Description
technical field [0001] The invention relates to the technical field and relates to a foldable double-layer refuge frame device that can be used in disaster sites, belonging to a refuge device; the technology adds folding and unfolding double-layer security under the premise that security personnel have enough space to avoid disasters, saving the cost of Storage space, and the double-layer structure has the characteristics of more stability and safety in disasters. Background technique [0002] In recent years, natural disasters and man-made accidents have occurred frequently around the world, seriously affecting the safety of people's lives and property. It is of great significance to develop a refuge frame device that can provide emergency refuge for escape heat sources and protect one's own life safety. In the urban environment, the refuge frame device should have the advantages of small storage volume and good sealing performance. Therefore, it is required that the spac...
