Technical Field
The utility model relates to a descender technical field specifically is a quick descender is used to rope.
Background
Descenders, i.e. protectors used for sports (extended training, mountain climbing, extreme, outdoor, etc.), for protecting operators in rescue (sometimes it is necessary to protect trapped people), also called "descent protectors". It is opposite to 'riser', and it can increase the friction force to the rope (steel cable, rail) to strengthen the buffer effect, so as to achieve the aim of 'slow descent'. Common descenders are mainly stop descent protectors, 8-rings (resume 8), MPDs (multi-function pulleys), and the like. Of course, we can also make a simple descender by winding the rope twice on a conventional D-shaped safety hook. With the continuous development of cities, high-rise buildings stand, and once a fire disaster occurs, high-rise people face how to escape quickly and safely. When a fire disaster happens, the elevator cannot be used, and when the stairs cannot pass, trapped people only need to wait for rescue of ground firefighters or implement self rescue. Sometimes, rescue work is limited by the height of the fire-fighting aerial ladder, rescue can not be smoothly carried out, and only high-rise trapped personnel are used for self rescue, and the high-rise trapped personnel can safely descend to the ground to save time and effectively.
The existing rope descender needs the foot to be wound on a rope or clamp the rope to move down to be favorable for safe landing in the descending process, and the rope descender needs to be operated and used well only by certain professional training, so that the rope descender is inconvenient to use by women, children, the old and the young, and can only control the descending speed of the descender in a single mode, and the descending speed is difficult to control.
