Self-rescue slow-descending device

Abstract

The invention discloses a self-rescue slow-descending device which comprises a safety rope fixing ring, a safety hook, a safety belt, a load-bearing fireproof rope, a housing, two rectangular friction plates, brake control handles, two semi-circular friction plates, a long rod and a short rod, wherein the rectangular friction plates, the brake control handle, the semi-circular friction plates, the long rod and the short rod are arranged in the housing; the safety rope fixing ring is connected with the upper end of the load-bearing fireproof rope; the safety hook is arranged on the outside of the housing and connected with the safety belt; the rectangular friction plates and the semi-circular friction plates are fixed in pairs on two inner sides of housing, with one pair higher than the other; the rectangular friction plates and the semi-circular friction plates correspondingly clamp the load-bearing fireproof rope; the upper semi-circular friction plate is connected with the long rod; the lower semi-circular friction plate is connected with the short rod; the long rod is hinged to the short rod; a spring is mounted between the short rod and the long rod, and the two ends of the springs are arranged on the long rod and the short rod respectively; and the brake control handles are mounted on the long rod and the short rod. Through such arrangement, the self-rescue slow-descending device disclosed by the invention can effectively help a user escape and is fast and efficient.

Description

technical field [0001] The invention relates to the field of rescue equipment, in particular to a self-rescue slow-down device. Background technique [0002] At present, the commonly used slow-descent rescue device is a high-altitude suspension escape device. The escape device is installed on a high building and descends at a constant speed along the load-bearing rope; when in use, it needs to be fixed and installed, and the speed cannot be controlled according to the actual situation; and it must be a person. After a safe landing, another person can use it, which seriously delays the time for self-rescue. [0003] In daily life, when encountering a sudden fire accident, because firefighters need a certain amount of time to prepare for rescue, and high-rise buildings are also difficult to implement rescue; this often misses the best escape time. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present invention...
