A self-rescue slow-down 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 casing, and two rectangular friction plates arranged in the casing, a brake control handle, two semicircular friction sheet, long rod and short rod; the safety rope fixing ring is connected to the upper end of the load-bearing fireproof rope; the safety hook is arranged on the outside of the shell and connected with the safety belt; wherein, the rectangular friction sheet and the semicircular friction sheet are paired with one side high and one side The lower part is fixed on both sides of the inner side of the shell, and the rectangular friction plate and the semicircular friction plate correspond to the load-bearing fireproof rope. The upper semicircular friction plate is connected to the long rod, the lower semicircular friction plate is connected to the short rod, and the long rod is connected to the short rod. Hinged, the spring is installed between the short rod and the long rod and the two ends are respectively arranged on the long rod and the short rod, and the brake control handle is housed on the long rod and the short rod. With such arrangement, the self-rescue slow-descent device disclosed in the present invention can effectively escape by itself, quickly and efficiently.

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...
