Escaping rope is meant on one side and connects the survivor, Yi Bian be fixed on the rope on the mechanical rescue curtain box.Escaping rope is wrapped on the roller bearing, should enough bear the weight of 150kg, and keeps not wearing out in 20 years, general steel wire rope or the steel band of using, the length of escaping rope is according to the height of building decision (seeing figure), on one side escaping rope be fixed on the roller bearing, Yi Bian be connected with the more comfortable safety belt of use.

4, safety belt

Safety belt is made by solid nylon braces, gently is bonded at the roller bearing below of ensconcing in the rescue curtain box with Pressure sensitive adhesive tape usually, and is connected with plastic window curtain rod used in everyday, and full-length can be according to people's frame size adjustments.When emergency takes place, pull down curtain with strength, the safety belt in the box that then can pull down the window curtain.Put on safety belt rapidly, jump out outside window then and both can.

5, gear train assembly

Gear train assembly is meant escaping rope is added in the gear train that power on the roller bearing passes to brake that use 2 groups of gears, like this, when one 75 kilograms people fell, the force of sliding friction that brake is born was 3-5 kilogram (seeing figure).

6, brake

Brake is meant that the power that gear train assembly is transmitted discharges by force of sliding friction, and with the brakes of the falling speed that reduces the people, brake is made of transverse axis, gear frame, brake scotch, damping leaf and adjuster.Operation principle is: connect gear train assembly by transverse axis, and power is passed to the gear frame that is fixed on the transverse axis; Gear frame passes to power the brake scotch that is enclosed within on the gear frame; Brake scotch then produces corresponding centrifugal force according to the speed of rotating speed, and masterpiece is used for the damping leaf of both sides, because the speed that the people falls is fast more, the centrifugal force of brake scotch is also big more, also big more with the frictional force of both sides damping leaf, like this, people's whereabouts is remained in certain velocity interval, be generally 1-2 meter per second (seeing figure).

7, speed regulator

Brake can reduce people's falling speed greatly by increasing frictional force, but can't keep the average rate of rope to descend, in order to make rope keep average rate to descend, be unlikely to take place the more and more faster problem of decrease speed, we settle speed regulator simultaneously in brake, speed regulator is made of an inertial spring wheel and escapement lever, utilizes the escapement principle of clock and watch, regulate rotating speed, guarantee that people's safe average rate descends.Because the main effect of speed regulator is prevention, so the inertial spring of our design is taken turns and the escapement lever swing speed is slower, mainly relies on brake to brake.
