Controllable-descend-speed type tower escape descend control knapsack

Abstract

The invention discloses a controllable-descend-speed type tower escape descend control knapsack. A head protecting device is fixed to the middle of the upper end of the rear wall of a knapsack body protector, and tightening bands used for binding the knapsack body protector and a human body are arranged on the two side walls of the knapsack body protector correspondingly. A controllable-descend-speed type descend control device is fixed to the interior of the front wall of the knapsack body protector, and a safety hook used for being hooked to a steel ring in a position near a window of a tower is fixed to the end of a rope coiled round the controllable-descend-speed type descend control device. A sleeve stay in the controllable-descend-speed type descend control device extends through a trouser leg on one side of the knapsack body protector and is fixed to the bottom of a corresponding protecting foot cover, and the descend speed is regulated in the modes that the controllable-descend-speed type descend control device is manually regulated; and the controllable-descend-speed type descend control device is controlled through the sleeve stay after the human feet kick downwards. According to the controllable-descend-speed type tower escape descend control knapsack, on the premise that the controllable-descend-speed type descend control device has a deceleration function, the descend speed can be controlled and regulated through the sleeve stay, the phenomenon that the head and limbs of the human body are knocked or scratched in the descend escape process is avoided, the application safety performance is high, materials are low in price, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of self-rescue equipment for high-rise buildings, and in particular relates to a slow-down knapsack for tower escape with controllable speed reduction. Background technique [0002] At present, elevators are commonly used in high-rise towers, which brings convenience to people in daily life. However, when a fire occurs in a high-rise tower or an earthquake occurs, the elevator cannot be used normally and cannot be used due to the safety hazards of the stairs. As a result of large casualties, escape has become an urgent need. In order to solve the above problems, a variety of high-rise escape backpacks have appeared, and these backpacks have a backpack-like shape. However, it cannot protect the head and limbs of the human body. At the same time, the descending speed of existing backpacks is uncontrollable, and there are potential safety hazards during use. To address the above problems, it is necessary to imp...

However, it cannot protect the head and limbs of the human body. At the same time, the descending speed of the existing backpacks is uncontrollable, and there are potential safety hazards during use. In view of the above problems, it is necessary to improve
