Retarder and escape bag with same

Abstract

The invention discloses a retarder. The retarder comprises two opposite mounting boards; a rope drum and a rotary shaft are rotationally fixed between the two mounting boards; the outer side of the rotary shaft in the circumferential direction is sleeved with the rope drum; an inner ring gear is arranged on the rope drum; the circumferential inner wall of the rope drum extends to the circumferential inner side to form a to-be-touched protrusion; a plurality of first gear shafts are fixed to the inner wall of one mounting board; the axes of the first gear shafts are parallel to the axis of therotary shaft; planet wheels are fixed to the first gear shafts; the rotary shaft is sleeved with a friction block holder and a sun wheel matched with the planet wheels in a fixed mode; the planet wheels are engaged with the inner ring gear; a notch with an opening towards the circumferential outer side is formed in the circumferential outer edge of the friction block holder; and a friction block is arranged inside the notch. The retarder has the advantages of being good in retarding effect and high in reliability. An escape bag has the advantages that the retarder is fixed more stably, wearingis convenient, and safety is high during use.

Description

technical field [0001] The invention relates to the field of escape equipment for high-floor disasters, in particular to a descending device and an escape bag with the descending device. Background technique [0002] At present, the pace of urbanization is getting faster and faster, and the tension of urban land has led to more and more high-rise buildings. When disasters such as fires occur on high floors, people have limited ways to evacuate the accident site, and the risk factor is high. In this context, high-floor slow-descent escape equipment was born, but the deceleration mechanism of the current slow-descent escape equipment has low reliability and poor slow-down effect, which makes the safety performance of the slow-descent escape equipment low. If it is possible to use would have extremely serious consequences. Contents of the invention [0003] The object of the present invention is to provide a descending device with good descending effect, high reliability and...
