Escape device for high-rise building

Abstract

The invention discloses an escape device for a high-rise building. The escape device comprises a shell, a first screw, two first fixing blocks, two gears and first limiting blocks; one end of the first screw is mounted on the left side of an inner cavity of the shell through a bearing, and the other end extends out of the right side of the shell; the two first fixing blocks are fixedly installed at the left end and the right end of the rear side of the inner cavity of the shell correspondingly and connected to the outer wall of the first screw in a sleeving mode; the gears are symmetrically installed on the rear side of the inner cavity of the shell through bearings correspondingly and engaged with the first screw correspondingly; the first limiting blocks are fixedly installed in the bearing connecting positions of the gears. According to the escape device for the high-rise building, in actual use, the friction force between a rope and a second limiting block and the friction force between the rope and a first limiting block can be adjusted according to the weight of a user, so that the falling speed of the user is changed, falling damage caused by too high speed is prevented, one end of the rope can be quickly tied to a firm place, time waste caused by manual knotting is avoided, and meanwhile, the knot can be prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of escape equipment, in particular to an escape device for high-rise buildings. Background technique [0002] The escape device is a self-rescue escape device for high-rise buildings. It is the best choice for the trapped people to escape quickly in the event of a sudden fire in a building or other high-rise buildings. Using this escape device, the trapped people can quickly escape from danger without the help of foreign aid; [0003] When common high-rise building escape devices are in use, the user’s falling speed is slowed down by increasing the friction force between the rope and the shell. This friction force is preset and the user cannot adjust it according to his own weight. There are some disadvantages: when the weight of the user is too large, the falling speed becomes faster, and it is easy to cause damage when landing. It is necessary to tie one end of the rope to a firm place indoors, but manual...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-rise building escape device to solve the problem that the friction force of the rope cannot be manually adjusted to change the falling speed and the manual knotting speed is too slow and not strong enough.
