Description

Slowly fall knapsack

Technical Field

The utility model relates to the technical field of fire-fighting safety escape products, in particular to a slowly-descending knapsack.

Background

When a fire disaster occurs, a person located in a high-rise building cannot quickly reach the ground by using an elevator and can only go down through stairs, but the escape speed by using the stairs is too slow, and once a large amount of smoke enters the stairs, the person cannot escape in time. Although people in a high building can escape through the firefighting scaling ladder with the help of firefighting rescue force, firefighting rescue force cannot necessarily arrive at the scene before disaster worsens the personal safety of a crisis, and the golden time for escaping can be shortened if rescue is waited blindly. In order to enable personnel in a high building to escape to the ground by themselves more quickly in the event of a disaster, related escape devices have been developed, wherein the slow descent escape device has the highest practicability. The descent control device of the descent control escape device is fixed in the building, and people can slowly descend and escape by using the free end of the descent control escape device; the existing escape descent control device generally adopts a friction deceleration mode to achieve a deceleration effect, but the internal friction resistance of the escape descent control device is not adjustable and is easy to lose efficacy, so that the safety use requirement cannot be met.
