Problems solved by technology

[0002] With the vigorous development of the construction industry and the rise of high-rise buildings, high-rise buildings such as high-rise buildings have become ubiquitous in our daily life, and it also brings a series of problems. Due to the thick smoke and fire, it is difficult for people to escape normally from the stairs and elevators. Surrounded by thick smoke, poisonous gas and flames, many people died in the sea of ​​flames. According to statistics, there are about 10,000 fires every day in the world, killing more than 2,000 people and injuring 3,000. -4,000 people, and the direct property loss caused by fires every year is more than 1 billion yuan, especially the severe vicious fires that cause dozens or hundreds of deaths continue to occur, and the lives of the people cannot be guaranteed
How to escape is an urgent problem to be solved at present. The traditional escape uses a slow descent device and a lifeline, and the use of a lifeline makes personal safety hidden dangers. A portable, safe, and easy-to-operate descending device to solve the problem of high-rise escape

Embodiment 1

[0029] Such as figure 1 , 2, 3, 4, 5, 6, and 7, a convenient knapsack-type descending device includes a housing 1 provided with a descending rope outlet 2, a friction plate and a descending rope 3, and the housing 1 is provided with a There is a double-shoulder strap 4. When escaping, the slow descender is carried on the body. One end of the double-shoulder strap 4 is fixed on the housing 1 by riveting. The other end of the double-shoulder strap 4 is provided with a buckle 5. The housing 1 There is a pull ring 6 for hooking the shoulder strap 4 matched with the buckle 5, and the pull ring 6 is arranged vertically. In order to adapt to the crowd of different body types, the said pull ring 6 is set in multiples, and different choices are made according to different body types. The pull ring 6 in the position further describes the housing 1, the housing includes left and right housings, the left and right housings are respectively provided with a plurality of connecting parts 7 ...

Embodiment 2

[0031] Such as Figure 8 , 9 , shown in 10 and 11, differs from Embodiment 1 in that: it also includes a control system, the control system includes a speed sensor 27 arranged on the rotating shaft 8, a signal receiver receiving the speed signal of the speed sensor 27, and processing speed The signal CPU sends the signal processed by the CPU to the signal transmitter of the control device, and the speed sensor 27, the signal receiver, and the signal transmitter are all electrically connected to the CPU. The control device includes a spline groove 28 arranged on the friction box 14 and a spline shaft 29 cooperating with the spline groove 28. One end of the spline shaft 29 is fixed to the secondary friction plate 13, which is well known to those skilled in the art. Fixing can be by welding or screw connection. The other end of the spline shaft 29 is fixed with a stopper 30 that prevents the spline shaft 29 from breaking away from the spline groove 28, and also includes a hydrau...

Embodiment 3

[0033] Such as Figure 12 As shown, the difference from Embodiments 1 and 2 is that the control device includes an adjustment rod 38 fixedly connected with the secondary friction plate 13, and the adjustment rod 38 is provided with threads and is threadedly connected with the friction box 14, and is connected with the adjustment rod 38. A handle is attached to the rod 38 .
