Stability after expansion.
Front-wheel support, arm-rest frame, hand push frame and supporting rack form four-bar mechanism, when vehicle frame is in unfolded state, after
Wheel support is located at double leval jib and surrounds on the diagonal line of quadrangle, forms the support to vehicle frame.
Link 305 is hinged on hand push frame 303, the end of the link 305 is hinged on the seat plate 308 of seat.
The side of seat plate 308 is transferred at the first hinge joint 307, is folded after being rotated convenient for seat plate 308.
Rear wheel support 301 is fixed with lock sleeve 309, and supporting rack 306 is hinged on locking lever apparatus 310.
In the present embodiment, lock sleeve 309 is equipped with slot, and the locking lever apparatus 310 that hand push frame 303 connects has and can stretch into
Telescopic rod in slot keeps vehicle frame supporting ＆ stablizing after deployment using the cooperation of telescopic rod and slot.Hand push frame 303 is by that can roll over
Two sections of folded compositions, are more convenient the folding and retraction of vehicle.
As seen in figures 3-6, the locking lever apparatus that hand push frame 303 and rear wheel support 301 are unfolded and fold by controlling vehicle frame
310 connections, locking lever apparatus include：
It is fixed on the lock sleeve (not shown) of 301 both sides of rear wheel support, which is equipped with locking slot；
It is rotatably assorted in 303 end of hand push frame and the telescopic rod 315 that coordinates with locking slot；
And for driving the axial activity of telescopic rod 315 to exit the rotating handle 313 and turnbarrel 314 of locking slot.
It further includes the assembly pipe 316 being fixed on hand push frame 303, the end movable sleeve of supporting rack 306 to lock lever apparatus 310
If for the connector 311 for the pipe 316 that is linked and packed, and assembling bottom of the pipe 316 by movable pull rod 312 and rear wheel support 301
It is hinged.
Telescopic rod 315 is two, is plugged in the both ends of assembly pipe 316 respectively, and compression spring is equipped between two telescopic rods 315
321, two telescopic rods 315 can enter locking slot to fix hand push frame and rear wheel support simultaneously, and compression spring 321 has telescopic rod 315
Flexible support keeps telescopic rod 315 to be inserted into tight slot.
In the present embodiment, telescopic rod 315 is movably arranged in assembly pipe 316 and circumferentially limits, and has outside the assembly pipe 316
The sleeve 322 that rotating handle 313 is circumferentially limited.
In rotating handle 313 double wedge, telescopic rod are equipped with equipped with the drive block 319 rotated synchronously, the side of drive block 319
315 fixing sleeve 323 has the groove that is engaged with double wedge, the side that double wedge is bonded with groove inclined-plane 320 each other.Drive block 319
It rotates, the sloped roof indentation slot inclined-plane on double wedge, simultaneously because telescopic rod 315 is on assembly 316 inner circumferential of pipe limit, groove inclined-plane
After stress, it is axially moved and enters in locking slot along the component driving telescopic rod 315 of body of rod axial direction.
It is equipped with axial groove in sleeve 322, the compression bar 317 with 319 circumferential clocking of turbine of drive block, compression bar are set in rotating handle 313
317 have the circumferential positive stop strip coordinated with axial groove.The circumferential positive stop strip of compression bar 317 can be caught in the axial groove in sleeve 322,
Keep rotating handle 131 circumferentially fixed, i.e. compression bar 317 and sleeve 322 is with being combined into two locking devices.
The spring 318 of support compression bar 317 is set in rotating handle 313, drive block 319, which has, adapts to the limit that compression bar 317 slides
Position slot.Spring 318 has thrust to compression bar 317, and compression bar 317 is kept to coordinate to be locked to rotating handle 313 with sleeve 322
Tightly, the active force that compression bar 317 overcomes spring 318 is pressed, circumferential positive stop strip is made to be exited out of axial groove, you can rotation rotating handle
313, and drive 319 pieces of driving to circumferentially rotate by compression bar 317, the limiting slot on drive block 319 is used to adapt to the axis of compression bar 317
To activity.
As is seen in figs 7-10, for the switching of shank backup plate 3 on vehicle frame 1, seat 2 is equipped with locating slot 201 and locating slot 202,
Have in shank backup plate 3 and coordinates to fix the elastic spacing one 203 of 3 angle of shank backup plate with locating slot.
Stop collar 208 is set in shank backup plate 3, elastic spacing one 203 is mounted in stop collar 208, is elastic spacing one 203
Activity provide be oriented to and limit.
In the present embodiment, elastic spacing one 203 includes clamping block 204, and spring 205, shank backup plate are equipped in clamping block 204
3 have the supporting rod for stretching into clamping block 204 and touching 205 end of spring.Spring 205 has thrust to clamping block 204, by card
Tight block 204 is pressed in locating slot, with Anti-extrusion.
Clamping block 204 is spaced apart two, and handle 206 is connected between two clamping blocks 204, same by handle 206
Two clamping blocks 204 of Shi Ladong, two clamping blocks 204 coordinate with locating slot simultaneously, more preferably to fix the angle of shank backup plate 3.
Clamping block 204 has the card-tight part 207 stretched into locating slot, and card-tight part 207 is wedge shaped, to make card-tight part
207 more smoothly enter in locating slot.
The tip of card-tight part 207 is equipped with latch, and locating slot 201 is equipped with the card slot for adapting to latch.Wherein, latch is interval
That arranges is multiple, and the quantity of card slot and latch adapts to, and fixes card-tight part 207 with more preferable limit, and avoid the inclined of card-tight part 207
It moves.
For the present embodiment when adjusting the angle of shank backup plate 3, rotation shank backup plate 3 simultaneously makes elastic spacing one 203 enter not
With in the locating slot of position so that shank backup plate 3 has different support angles.
As figs 11-13, the bottom of the wheel 104 of 301 both sides of rear wheel frame, vehicle frame 1 is equipped with fixing sleeve 103, wheel
104 106 activity of wheel shaft is plugged in fixing sleeve 103.

Between be equipped with brake lever 101, pedal 102 is fixed on the side of brake lever 101, and pedal 102 drives 101 turns of brake lever when trampling
It is dynamic.
The cam 107 rotated synchronously with brake lever 101 is housed, and the sliding shoe driven by cam 107 in fixing sleeve 103
108；There is sliding shoe 108 brake axle 109 coordinated with brake tooth 105, the brake axle 109 can enter adjacent two brakes tooth 105
Between card slot in, brake to wheel.
In the present embodiment, the circumferential surface of cam 107 is equipped with the lug boss of top pressure sliding shoe 108, between lug boss and sliding shoe 108
It is connected with supporting rod 112, the both ends of the supporting rod 112 coordinate with lug boss and the switching of sliding shoe 108 respectively.
The brake structure of the present embodiment is equipped with the locating part of control 107 rotational angle of cam so that the angle of rotation of cam 107
Degree is adapted with the stroke of brake axle 109 just.Locating part is the arc groove 110 of the circumferential surface indent of cam 107, the arc groove
110 bottom surface reclines the wheel shaft 106 of wheel 104, has limit slope surface between 107 circumferential surface of both ends and cam of arc groove 110.Work as arc
When 110 bottom surface of shape slot touch the rotation of wheel shaft 106, limit slope surface is contacted with wheel shaft 106 to stop the rotation of cam 107.
There is the limit chamber for accommodating sliding shoe 108 in fixing sleeve 103, be used for the glide direction of limit slippage block 108, and limit
The bottom of position chamber is equipped with the spring 111 of support sliding shoe 108.Spring 111 has certain buffering to pedal, make its when trampling by
Power is relatively stable, and when releasing brake, spring can provide steering restoring force for pedal.
The foregoing is merely the preferable implementation examples of the present invention, are not intended to restrict the invention, it is all in spirit of that invention and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
