Abstract

The invention relates to an adjustable speed descender, comprising a left speed-adjusting handle, a right speed-adjusting handle and a main support. A handle return spring in the lower middle of the left speed-adjusting handle is fixedly connected with the lower middle of the right speed-adjusting handle. The left speed-adjusting handle and the right speed-adjusting handle are distributed symmetrically on two sides of the main support, and their middles are rotatably connected with the main support through a pin. Speed may be adjusted by holding the handles by hand, thus operating is convenient. Speed adjusting range may be determined according to hand holding force, and stepless speed adjusting may be given. The descender may be fixed safely to any aerial position through a fixing pin. The adjustable speed descender is simple in structure, convenient to carry along, low in manufacturing cost, conducive to popularization and application, and widely applicable to aerial operation, downhill, aerial escape and the like.

Description

technical field [0001] The invention relates to a speed-adjustable descender, which belongs to a high-altitude rapid descent device. Background technique [0002] With the improvement of people's living standards, mountaineering tourism has become an important way for more people to enjoy life and relax themselves. Downhill climbing has become a favorite sport for mountaineering enthusiasts. In mountaineering downhill, the most commonly used is rope downhill. Rope rappelling uses ropes to lower a person from a high place to a low place. How to use ropes to safely and stably descend people has become an important content in the study of mountaineering descenders. [0003] Existing rappelling is mostly a kind of descender that utilizes the rope to pass through the belt hole, and adjusts the friction between the rope and the descender by adjusting the number of holes through which the rope passes through the descender. There is also a descender that utilizes mechanical fric...
