The invention relates to the technical field of fire fighting tools, and discloses a fire fighting safety quick-lowering rod, which comprises an inner sleeve and an outer sleeve, wherein the inner hollow structure of the inner sleeve is used as an outer compression air cavity, the inner hollow structure of the outer sleeve is used as an inner compression air cavity, the inner sleeve is sleeved with the outer sleeve end to end, the outer compression air cavity communicates with the inner compression air cavity, a pair of outer sealing pistons are cooperatively arranged at two ends of the innerwall of the outer compression air cavity, a pair of inner sealing pistons are cooperatively arranged at two ends of the inner wall of the inner compression air cavity, the outer sealing pistons are connected end to end by a return spring, the inner sealing pistons are also connected end to end by a return spring, and the two ends of the quick-lowering rod are sealed by an upper jacking part and alower treading part which are detachably connected. The fire fighting safety quick-lowering rod has the beneficial effects that the fire fighting safety quick-lowering rod can be applied to fire fighting lifesaving of jumping from a high position, has a reliable buffering effect, is safe and convenient to use, and can win more survival time for fire fighters and lifesaving personnel.
Description
technical field [0001] The invention relates to the technical field of fire-fighting appliances, in particular to a fire-fighting safety downhill rod. Background technique [0002] When a fire breaks out, some people choose to jump out of the fire, but because some floors are too high, serious casualties are caused, and the rope may be burnt at high temperature. Climbing aids for firefighters, the most important thing is to help firefighters jump from high places without injury. Existing fire poles cannot provide effective cushioning when firefighters jump from high places, are not safe and convenient to use, and cannot win more survival time for firefighters and lifeguards. For example: Chinese Patent Application Announcement No. CN108394773A , the application announcement date was August 14, 2018, and the name of the invention is an emergency fire rod for elevators, including rubber pads, mounting blocks, reverse screws, forward sleeves, expansion frames, expansion tool h...
