Adjustable descending device

Abstract

The invention provides an adjustable descending device. The adjustable descending device comprises a descending body, a hinged connection pin shaft and a rotating handle. The descending body comprises a hinged end and a descending free end which are oppositely arranged. The descending body is provided with a first limiting hole and at least three rope threading hole. The rotating handle comprises a rotating part and a handle operating part connected with the rotating part. The rotating part is provided with a hanging buckle ring and a second limiting hole. The rotating part is hinged to the hinged end through the hinged connection pin shaft. The first limiting hole and the second limiting hole can at least partially overlap to form an adjustable overlapped region used for containing a rope. When the rope is arranged in the overlapped region in a penetrating manner, tensile force which is exerted on the hanging buckle ring and equal to the gravity of a descending person applies torque to the hinged connection pin shaft, and the torque is increased while the area of the overlapped region is increased and is decreased while the area of the overlapped region is decreased. The adjustable descending device can adjust friction force between the rope and the descending device, fix a human body at high altitude and liberate the two hands.

Description

technical field [0001] The invention relates to a device for descending from a high place, in particular to an adjustable descender. Background technique [0002] In natural disasters such as fires and earthquakes, how to actively avoid danger, scientifically save oneself and effectively get out of danger has become an important topic and an indispensable skill. [0003] The working principle of the descender in the prior art is to adjust the frictional force between the rope and the descender by using the number of holes through which the rope passes through the descender. When the human body is in the process of descending, the hand needs to always hold the free end of the rope to adjust the friction between the rope and the descender, so as to control the speed of the human body's descent. Therefore, the hands cannot be freed to perform other tasks at high altitude during the descent. . More importantly, if a person is frightened at a high altitude, the human body will ...

AI Technical Summary

Problems solved by technology

When the human body is in the process of descending, the hand needs to always hold the free end of the rope to adjust the friction between the rope and the descender, so as to control the speed of the human body's descent. Therefore, the hands cannot be freed to perform other tasks at high altitude during the descent.

More importantly, if a person is frightened at a high altitude, the human body will instinctively let go of the hand, resulting in a decrease in the friction between the rope and the descender, which may cause the human body to accelerate down at high altitude and cause casualties
