Pushing hands is braked, occupant can not automatic brake, and existing wheelchair is without parking braking, when they are seated wheelchair trip, very
Easily because wheelchair is out of control without parking braking, injury is ultimately resulted in, there is certain potential safety hazard.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of walking-aided wheelchair braking mechanism, be
One braking mechanism is set again on wheelchair, brake function is realized by handrail front end.
The technical scheme that the utility model is used：A kind of brake gear of walking-aided wheelchair, by handrail, wheelchair frame, turns
Constituted to pin, controlling organization and arrestment mechanism, the controlling organization is made up of control chute, joystick, parking braking groove；
The arrestment mechanism is made up of braking steel cable, caliper, brake block；It is characterized in that：The braking mechanism is arranged on before handrail
End, arrestment mechanism is arranged on steering pin；Handrail and steering pin are connected by the vehicle frame of wheelchair.
It is partly that handle, lower part are leads on described joystick, lead is moved in control chute.
Described braking steel cable one end is fixed on joystick, and the other end is fixed on caliper upper end；Control chute
The front end of handrail is located at, joystick moves in control chute and then pulls braking steel cable to drive caliper action, caliper
Steering pin by bearing pin respectively with the side of front-wheel two is attached.
Control chute end side on described control chute offers parking braking groove, and joystick is drawn into control
Chute end processed, rotating joystick can be such that it is stuck in parking braking groove, and joystick can not return to the position of front end, now
For parking braking.
Described brake block is fixed on the middle part of caliper, and brake block rubbing surface is contacted with front-wheel wheel rim；Pull braking steel
Rope causes caliper to be rotated by bearing pin around pin is turned to, and then drive brake block is leaned against on front-wheel wheel rim, the two it
Between produce rubbing action, braked.
The utility model, using a braking mechanism is set again on wheelchair, realizes brake function by handrail front end, makes
User can voluntarily control walking-aided wheelchair speed when being sitting on wheelchair and carry out parking to walking-aided wheelchair when stopping moving ahead rest
Braking.Avoid user's wheelchair caused by wheelchair is without parking braking to tumble and injured, also further increase the safety of wheelchair
Property.

Embodiment
Known by Fig. 1, a kind of braking mechanism of walking-aided wheelchair of the utility model, by handrail 1, vehicle frame 5, front-wheel 7, steering pin
8th, controlling organization and arrestment mechanism composition, the controlling organization and arrestment mechanism are separately positioned on handrail front end and turn to pin
On；The controlling organization is made up of control chute 2, joystick 3, parking braking groove 9；The arrestment mechanism is by caliper 6, system
Motion block 11, braking steel cable 4 are constituted.
Known by Fig. 2, Fig. 3, Fig. 4, be partly handle on joystick 3, lower part is lead 12, control chute 2 is direct
Opened up on handrail 1, the lead 12 is cylinder, and the diameter of lead 12 should be less than controlling the diameter of chute 2, pull
During handle, lead 12 can be moved in control chute 2, and the front end of lead 12 is fixed with braking steel cable 4, and then pulls system
Dynamic steel cable 4, produces braking action；The side of control chute end 14 offers parking braking groove 9, and handle is drawn into control
Chute end 14, then rotates joystick 3 toward side direction, joystick 3 can be made to be stuck in parking braking groove 9, controls hand
Handle 3 can not return to the position of front end, be now parking braking.
Braking steel cable 4 other end is fixedly connected using the form of bifurcated with caliper upper end 16, in caliper 6
Portion is attached with turning to pin by bearing pin 10, and brake block 11 is fixed in the middle part of caliper, the rubbing surface of brake block 11 and front-wheel
Wheel rim 15 is contacted, and pulls braking steel cable 4 to may be such that caliper 6 is rotated by bearing pin 10 around pin 8 is turned to, and then drive
Brake block 11 is leaned against on front-wheel wheel rim 15, and rubbing action is produced therebetween, is braked.
When walking-aided wheelchair user feels that speed is too fast in the process of seating, it can be pulled and controlled along the direction of handrail 1 with hand
Handle 3, and then drive caliper 6 to carry out braking deceleration by braking steel cable 4, moved by lead 12 in control chute 2
Displacement produce correspondingly sized braking effect, joystick 3 pulls displacement to get over along the rear of handrail 1 in control chute 2
Greatly, brake force is bigger；When user stops rest, joystick 3 can be moved to control chute end 14 to, then turn to side
Dynamic joystick 3 so that joystick 3 is stuck in parking braking groove 9, such walking-aided wheelchair is i.e. by continuous braking, it is impossible to move ahead,
Wheelchair is avoided to occur security incident from line slip.
The utility model optimum implementation is the left side that above-mentioned braking mechanism is arranged in walking-aided wheelchair using symmetrical mode
In right handrail, user can be when taking, and right-hand man can synchronize braking deceleration.Braking steel cable 4 is externally provided with wear-resisting outer tube, makes
Dynamic steel cable 4 is fixed along vehicle frame, and attractive in appearance, stability might as well.Joystick 3 can be designed using ergonomics, improve behaviour
Vertical comfortableness, can also be automatically controlled by the way of motor.
Principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.
