Wherein the first auxiliary shaft 6 and the second auxiliary shaft 7 are fixed around the safety rope 5, the third auxiliary shaft 8 can increase or reduce the number of the safety rope 5 before escaping according to the weight, and the fixing hook 4 is used for preventing the rope from slipping.

The utility model discloses a theory of operation:

during falling, the safety rope 5 generates a large friction force due to multiple turns around the shaft, and the friction force can counteract acceleration caused by a part of gravity, so that the acceleration during falling is maintained in a safe range. The whole device is arranged in a special backpack, the backpack strap is of a double-person parachute-jumping strap type structure, and two persons can escape at the same time.

Meanwhile, the winding mode of the safety rope 5 among the first auxiliary shaft 6, the second auxiliary shaft 7 and the third auxiliary shaft 8 can be divided into different winding mode intervals according to the body weight.

The winding mode of the corresponding interval is determined to automatically wind the safety rope 5 according to the weight interval of the escape person, the winding mode is updated frequently according to the weight, and meanwhile, a fixing ring is installed at a proper position in a home and is used for being hooked with the fixing hook 4.

The utility model discloses a theoretical foundation:

1. the friction between the rope and the cylinder increases as the number of turns of the rope around the cylinder increases.

2. The pressure per unit length of the rope, i.e. the pressure density, applied to the cylinder is proportional to the tension at the two ends of the rope and inversely proportional to the radius of the cross section of the cylinder.

(the two sections are selected from physical teacher 35, 10 th period of friction analysis of rope wound cylinder)

According to the formula provided in the thesis, the relation between the number of turns wound when the weight is decelerated to the same speed and the weight can be calculated, the weight is divided into intervals, the number of turns on the first auxiliary shaft 6 and the second auxiliary shaft 7 in each interval is different, and the third auxiliary shaft 8 is used for adjustment in the same interval. This covers a considerable weight range, while within range adjustments can be effected.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement, component separation or combination made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
