The weight scale line 26 directly proportional to the drum brake elasticity of respective side drum brake assembly 18 and weight scale line are formed on the Shell Plate of side
26 are distributed in around the outer ring of ratchet 15, and refer to the index line being set on ratchet 15 by rotating ratchet 15
It realizes in side drum brake assembly 18 and is adjusted in drum brake piece 20 and drum brake ring 14 after to weight scale line 26 corresponding with user's weight
The adjusting of frictional force between wall, the ratchet 15 will be in the tooth sockets of unidirectional rotation stop arm 17 insertion ratchet 15 after adjusting
Complete the fixation after frictional force is adjusted between 11 side drum brake assembly 18 of outer casing frame and drum brake ring 14 to drum brake adjustment axis 19；Specifically
, the reduction of speed control mechanism includes lateral galianconism 22 and casing drawstring 10, transverse direction 22 end of galianconism and rotational installation in
19 end of drum brake adjustment axis on 11 other side side wall of outer casing frame is fixedly connected and 10 upper end of casing drawstring and lateral galianconism 22 are solid
Fixed connection, described sleeve pipe drawstring 10 extend through the trouser legs 4 of side in backpack body protector 1 and are fixed on corresponding 6 bottom of leggings, and
It is pedaled after casing drawstring 10 drives bar blocks 21 to rotate by drum brake adjustment axis 19 by people underfooting and changes 11 other side drum brake of outer casing frame
The adjusting of decrease speed is realized between assembly 18 and drum brake ring 14 after frictional force；Specifically, the head restraint is peace
The full helmet 23 and fixing belt 24, the flexible material of 23 lower end of crash helmet are fixed on 1 rear wall upper center of backpack body protector, and
23 lower end side of crash helmet is fixed in 24 one end of fixing belt, the 23 lower end other side of crash helmet be fixed with connection ring 25 and
24 other end of fixing belt is fixed on 24 outside zone face of fixing belt after passing through connection ring 25 by velcro, specifically, the packet
Body protector 1, trouser legs 4, sleeve 3, hand guard glove 5 and leggings 6 be wear-resistant flexible material be made and backpack body protector 1, trouser legs 4, sleeve
The filler with buffer function is filled with inside son 3, hand guard glove 5 and leggings 6.
Working principle: firstly, dressing by wearing opening 2, after four limbs are put on, crash helmet 23, which will be applied to head, to be consolidated
Determine 24 other end of band to be fixed on 24 outside zone face of fixing belt after connection ring 25 by velcro, tight stripe 7 will after tightening
Backpack body protector 1 and human body bundle, and then the auxiliary catch 9 of 8 end of rope is mounted on the steel loop of high building Lin Chuanchu, adjust around
Frictional force between the drum brake assembly 18 of 12 side of rope support and corresponding 14 inner wall of drum brake ring, adjustment process are as follows: passing through rotation
Ratchet 15 adjusts the bar blocks 21 of 19 one end of drum brake adjustment axis in drum brake assembly 18 corresponding with ratchet 15, makes bar shaped
Block 21 pushes up two panels drum brake piece 20 after rotating outward, to increase drum brake piece 20 and between 12 side drum brake ring of rope support, 14 inner wall
Frictional force, achieve speed reduction；In use process, if it find that decrease speed is somewhat fast, it can be by foot control system around rope support
Frictional force between corresponding 14 inner wall of drum brake ring of drum brake assembly more than 18 of 12 other sides, adjustment process are as follows: after kicking one's legs downwards
So that another drum brake assembly 18 is worked, i.e., pulls lateral galianconism 22 to make on 11 other side side wall of outer casing frame by casing drawstring 10
After drum brake adjustment axis 19 rotates, the two panels drum brake piece 20 in another drum brake assembly 18 is pushed up outward by bar blocks 21, thus
Increase drum brake piece 20 and the frictional force between 12 other side drum brake ring of rope support, 14 inner wall in another drum brake assembly 18, subtracts
Fine descent rate, achievees the purpose that speed regulation, guarantees user's safe landing, and in this structure, ratchet 15 is designed as only inverse
Hour hands rotation, i.e., with the rotation direction of axis 13 on the contrary, and unidirectional rotation stop arm 17 only rotates clockwise, adjusting ratchet 15
When, ratchet 15 is rotated counterclockwise to be pushed up two panels drum brake piece 20 outward by bar blocks 21 after rotating drum brake adjustment axis 19
The adjusting that drum brake piece 20 and 14 inner wall frictional force of drum brake ring are realized after opening, when adjusting ratchet 15, unidirectional rotation stop arm 17
It takes advantage of a situation and rotates clockwise, after the completion of adjusting, when axis 13 rotates, ratchet 15 can be prevented suitable under the action of unidirectional rotation stop arm 17
Hour hands rotation；By experiment, the relationship of speed and user's weight is limited according to 0.3m/s, in 15 side of ratchet in shell
Weight scale line 26 (as unit of 10 kilograms) are set on Shell Plate on frame 11, to vary with each individual, it is total to reach adjusting drum brake
At the effect of 18 drum brake tightness, the crowd for adapting to different weight is used.
Reduction of speed controllable type ramp-down device is set to inside 1 antetheca of backpack body protector by the technical program, is delayed by reduction of speed controllable type
Falling unit itself provides decline frictional force while reach deceleration, is pedaled by people underfooting and is connect with reduction of speed controllable type ramp-down device
Casing drawstring 10 realizes the control and adjusting of decrease speed, easy to adjust, user can according to the needs of decrease speed at any time into
Row is adjusted, and sleeve 3 and trouser legs 4 with hand guard glove 5 and leggings 6 are fixed on backpack body protector 1 and consolidates head restraint
It is made into garment-like after 1 upper center of backpack body protector, the four limbs of human body and head are carried out during declining escape
Protection, the phenomenon that effectively preventing gouge during decline is escaped or scratch human body head and four limbs, usage safety performance is high, leads to
The casing drawstring 10 connected with the lateral galianconism 22 on 11 other side Shell Plate of outer casing frame is pedaled in remarkable underfooting, by lateral 22 band of galianconism
After the dynamic bar blocks 21 connecting with drum brake adjustment axis 16 rotate, drum brake piece 20 and drum brake are increased after extending out two panels drum brake piece 20
The frictional force of 14 inner wall of ring, to realize decrease speed manual control and adjust, flexible adjustment is convenient, guarantee people's safety
Land, structure is simple, and material is cheap, greatly reduces the cost of slow drop knapsack, application easy to spread.
Above-described embodiment, only presently preferred embodiments of the present invention, is not intended to limit the invention practical range, therefore all with this
The equivalence changes that content described in invention claim is done should all be included within scope of the invention as claimed.
