Problems solved by technology
The technical problem in the known technology is that this solution does not disclose a specific automatic speed control mechanism that can be adapted to escapers of different weights and accurately generate the required friction force, such as the fixed slanting block and the slanting block of the sliding slanting block. If the angle of the slide is too fast or locked, although the friction force can be adjusted through the manual speed control mechanism, this is only applicable to the situation of sliding too fast, and the escaper needs to have experience in use or pass the on-the-spot Calmly groping to master, this requirement is obviously unrealistic, besides, for the locked situation, the manual speed control mechanism has no effect

Embodiment Construction
[0007] The slow-falling device of the present invention is made of double hinge housing and two sets of identical speed control mechanisms, which are called an upper speed control mechanism and a lower speed control mechanism respectively. The folio hinge shell is composed of two leaf shells, namely the left shell 1 and the right shell 2, which are connected by the hinge shaft 3, see figure 1 As shown, the left cover 1 and the right cover 2 are locked by the safety catch 4 when they are closed. The speed control mechanism includes self-driving, centrifugal, guiding, feedback, braking and hand-driven parts. see figure 1 , figure 2 , image 3 , the self-driving part is made up of friction wheel 5 and arc-shaped briquetting block 6, the rim of friction wheel 5 has a groove, the arc surface of arc-shaped briquetting block 6 is close to the rim of friction wheel 5, and the axle of friction wheel 5 of the upper speed control mechanism is fixed on On the left page case 1, the ar...

The invention discloses a bisectional type tiptronic self-locking prevention descent control device, which can realize simultaneous escape of multiple people on multiple floors in a high-rise building and belongs to the technical field of lifesaving appliances. A separated type high-rise escaper in the prior art tends to slide downwards too fast or be locked. The descent control device comprises a divided hinge shell and two same sets of speed controlling mechanisms; the divided hinge shell is formed by connecting two hinge shells through a hinge shaft; each speed controlling mechanism comprises a self-driving part, a centrifuging part, a guiding part, a feedback part, a braking part and a hand-driving part, wherein each centrifuging part is coaxial to each self-driving part and abutted against each guiding part, each guiding part, each feedback part and ach braking part are sequentially connected, and each hand-driving part is directly connected with each brake part; and the braking part in one set of the speed controlling mechanism is in sliding fit with the self-driving part of the other set of speed-controlling part, the self-driving part and the centrifuging part in one set of the speed controlling mechanism are located in the same hinge shell of the guiding part, the feedback part, the braking part and the hand-driving part of the other set of speed controlling mechanism, and other parts of the two sets of speed controlling mechanism are located in the other hinge shell.
Description
technical field [0001] The invention relates to a split-type manual self-integrated anti-self-locking slow-down device, which can realize the simultaneous escape of multiple people on multiple floors of a high-rise building, and belongs to the technical field of life-saving equipment. Background technique [0002] With the development of society, there are more and more high-rise buildings. However, when unexpected dangers such as fires and gas leaks occur in high-rise buildings, or when an earthquake occurs, how people in the high-rise buildings escape in time and smoothly becomes a technical problem. A Chinese patent application number 200520030827.3 discloses a technical solution called "separate high-rise escape device". The solution consists of a suspension part and a sliding part, which are separated at ordinary times, and the sliding part cooperates with the suspension part to realize high-rise escape when in use. The core component of the suspension part is a steel...
