Axis 372, friction pulley 373 and the friction portion 374 for generating frictional force with frame body 350, the diameter of driving wheel 361 are more than driven wheel
371 diameter, friction pulley 373 are sheathed on the one side of the separate driven wheel 371 of connecting shaft 372, and friction portion 374 is located at friction pulley
Between 373 and frame body 350, i.e. friction portion 374 sets gradually connection from inside to outside between friction pulley 373 and end cap 353
Axis 372, friction pulley 373, friction portion 374 and end cap 353.
Fixing piece 310 is hung on the hook installed in advance, user from high level jump off when, rope 320 constantly stretch
Out, the rich around cheese for setting rope 320 is made constantly to rotate, so as to which the driving wheel being synchronized with the movement with around cheese 361 be driven to rotate, by
It is more than the diameter of driven wheel 371 in the diameter of driving wheel 361, the driven wheel 371 engaged with driving wheel 361 will more quickly
It rotates, so that 372 quick rotation of connecting shaft, friction pulley 373 in connecting shaft 372 also quick rotation is set in, due to centrifugation
The effect of power, during 374 high-speed rotation of friction portion, the radial direction that friction portion 374 can be directed away from friction pulley 373 is directed away from
The direction movement of friction pulley 373, so that friction portion 374 is contacted with end cap 353, makes to generate between friction portion 374 and end cap 353
Frictional force, so as to achieve the purpose that slow down decrease speed.By the friction between friction portion 374 and end cap 353, user can pacify
Steadily decline entirely, achieve the purpose that high-rise escape.
Refer to Fig. 2 and Fig. 3, in the present embodiment, end cap 353 includes cover board 354 and is disposed around the side of 354 periphery of cover board
Siding 355, the one side of the separate cover board 354 of sidewall paneling 355 are arranged at the second installing plate 352, and friction portion 374 is along friction pulley 373
Radial direction movement when with the interior wall friction of sidewall paneling 355, make to generate friction between friction portion 374 and sidewall paneling 355
Power, so as to be braked to high-rise escaping descent control device 300.
In the present embodiment, the inner wall contacted on sidewall paneling 355 with friction portion 374 is provided with the cell wall 381 of a plurality of circular ring shape,
The inner wall contacted on sidewall paneling 355 with friction portion 374 is rough, can increase rubbing between friction portion 374 and sidewall paneling 355
Wipe power；Meanwhile if the cell wall 381 of circular ring shape is not provided with, when 374 long-time of friction portion rubs with sidewall paneling 355, then
The powder generated on 374 surface of friction portion due to friction can be made to be sticked to the inner wall of sidewall paneling 355, make its skidding, so, in side
The inner wall of siding 355 sets the cell wall 381 of circular ring shape, and the powder generated due to friction falls into the cell wall 381 of circular ring shape, will not
The friction between friction portion 374 and 355 inner wall of sidewall paneling is influenced, achievees the purpose that uniform descent.
Preferably, there are two reducing gear 370 is set, two reducing gears 370 are respectively arranged at the two of driving wheel 361
Side.I.e. driven wheel 371, friction pulley 373 and friction portion 374 are respectively provided with two, the driven wheel 371 of each reducing gear 370, friction
The connection mode in wheel 373 and friction portion 374 is identical, and the axis of two driven wheels 371 is set by the axisymmetrical of driving wheel 361
Put, further improve the safety in utilization of high-rise escaping descent control device 300, user when high-rise escaping descent control device 300 are used,
It is capable of the decline of more safety and stability, user is avoided to generate a panic when in use.
It is with what reducing gear 370 coordinated：Sidewall paneling 355 be two annular side plates, the friction of a reducing gear 370
When the radial direction of portion 374 along corresponding friction pulley 373 moves with the interior wall friction of side plate.Then braking when
It waits, the friction portion 374 of two reducing gears 370 can rub with side plate, further improve high-rise escaping descent control device 300
The effect of braking further improves the safety in utilization of high-rise escaping descent control device 300, achievees the effect that more smoothly to decline.
Preferably, there are two the friction portion 374 of each reducing gear 370 is set, two friction portions 374 are arranged at intervals and lead to
Spring 378 is crossed to connect.When 373 high-speed rotation of friction pulley, two friction portions 374 are both facing to the side away from friction pulley 373
To movement, if the velocity of rotation of friction pulley 373 is too fast, the centrifugal force in friction portion 374 then can be excessive, then friction portion 374
It will be in close contact with sidewall paneling 355, so as to which locking phenomenon easily occur, and cannot make between friction portion 374 and sidewall paneling 355
Frictional force is generated, so, spring 378 between two friction portions 374 is set, is i.e. two bullets are set between two friction portions 374
Spring 378, the both ends of each spring 378 connect a friction portion 374, the contact between friction portion 374 and sidewall paneling 355 respectively
