Fig. 3 is that the present invention is arranged on the structural representation on wheel-chair.
Specific embodiment
As illustrated, the structure master that Fig. 1 is the present invention shows schematic diagram, Fig. 2 is the structure schematic side view of the present invention,
A kind of wheelchair depletion of QI brake gear, including：On one brake fixed part 1, one handle 2, is rotatably installed to stop
Car bar 4, the two ends of a dowel steel 3 are rotatably coupled to handle 2 respectively, in brake lever 4, in brake lever 4
Brake block 5 is installed, by pulling handle 2, handle 2 drives dowel steel 3, and then drives brake lever 4 to make
Brake block 5 moves the brake that wheel-chair realized by wheel, and brake block 5 includes：One main brake piece brake block 54,
Both sides brake block brake block 52, both sides brake block brake block 52 is mutually perpendicular to main brake piece brake block 54, main
Brake block brake block 54 is coordinated with both sides brake block brake block 52, provides good braking effect in tire deflation.
Handle 2 includes：One L-type portion 22 and a force application rod 21, one end of force application rod 21 is fixed on L-type portion 22
One end, a first rotating shaft 61 passes through the middle part in L-type portion 22 to be fixed on brake fixed part 1.
Force application rod 21 can be arranged on the side in L-type portion 22, has bending so that exerting a force in the middle part of force application rod 21
Bar 21 is arranged on wheelchair force application rod 21 side wheelchair rear afterwards, is easy to user operation.
The other end of force application rod 21 can have holds set, holds set and can adopt rigid plastics, it would however also be possible to employ be anti-skidding
Rubber, thus obtain better grip feeling.
One second rotating shaft 62 passes through one end of brake lever 4 to be fixed on brake fixed part 1, and brake block 5 is fixed on
The other end of brake lever 4.
One end of dowel steel 3 is rotatably fixed on the other end in L-type portion 22 by one the 3rd rotating shaft 63, passes
The other end of the I of power bar 3 is rotatably fixed on the middle part of brake lever 4 by one the 4th rotating shaft 64.
Preferably, dowel steel 3 two, two dowel steels 3 be arranged in parallel, and two dowel steels 3 are separately fixed at L-type
Portion 22, the both sides of brake lever 4 are so that the structure of dowel steel 3 is more stable.
More preferably, it is connected with banking stop between two dowel steels 3, banking stop is offseted with the bottom in L-type portion 22, from
And prevent handle 2 in default conditions, that is, in the state of not braking, move forward, and, banking stop is permissible
The further Stability Analysis of Structures degree increasing dowel steel 3.
It is connected with a back-moving spring 7, back-moving spring 7 is around being located at second turn between brake lever 4 and brake fixed part 1
On axle 62, made when there is no external force effect by arranging back-moving spring 7, the tire of brake block 5 and wheel is not
Contact can be produced.
Preferably, brake fixed part 1 has perforate, one section of bending of back-moving spring 7 is fixed in perforate,
The other end of back-moving spring 7 is fixed on the side wall of brake lever 4.
First rotating shaft 61, the second rotating shaft 62, the 3rd rotating shaft 63, the 4th rotating shaft 64 are mutually parallel.First turn
Axle 61, the second rotating shaft 62 are arranged on same level and highly go up.
In one embodiment of the invention, the brake lever 4 of the present invention be fixed with brake block 5 one end vertically outside
Bending, brake block 5 also includes a stator, and stator is perpendicular with main brake piece brake block 54, stator and
The vertically outside kink phase of brake block 5 is fixed.
Preferably, stator is carried out admittedly by fixed screw and hold-doun nut with the vertical bending part of brake block 5
Fixed, be easy to dismount and brake block 5 replacing,
Fig. 3 is the structural representation that the present invention is arranged on wheel-chair, and in specific implementation process, will brake fixed part
1 is fixed on below the handrail of wheelchair, and can fix is the special standing part below wheelchair armrest, completes to fix
Afterwards, main brake piece brake block 54 is towards wheel, but do not contact with wheel, and both sides brake block brake block 52 is same
Towards wheel, both sides brake block brake block 52 towards be wheel side wall, both sides brake block brake block 52 and car
Wheel does not contact, and when needing to be braked, user pulls handle 2, and handle 2 passes through dowel steel 3 power transmission to brake
Bar 4, brake lever 4 drives main brake piece brake block 54 to press close to wheel tyre and realizes skidding.Running flat
During be braked, because tire is excessively soft, main brake piece brake block 54 braking efficiency declines, and now, side
Brake block brake block 52 is close to sidewall, realizes braking.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art
Just many modifications and variations can be made according to the design of the present invention without creative work.Therefore, all this technology necks
In domain, technical staff passes through logical analyses, reasoning or limited under this invention's idea on the basis of existing technology
Test available technical scheme, all should be in the protection domain being defined in the patent claims.
