Axis is equipped with cam, and groove is equipped on the inside of the cam and forms the first knuckle lock loose slot, groove type is equipped on the outside of the cam
Into cam groove.
The upper end of the after-poppet pipe is fixed with after-poppet cushion block 20, and traction silk braid is equipped in the after-poppet cushion block and is fixed
Slot 201,202 and first traction fiber via 203 of traction fiber slot are crossed slot 111 and second equipped with traction fiber in the recoil backing plate and are led
Draw a via 112, second traction fiber sequentially passes through the traction silk braid fixing groove of the after-poppet cushion block, traction fiber slot,
The traction fiber of one traction fiber via into the preceding seating pad crosses slot and the second traction fiber is crossed and is fixedly connected on the seating pad lock
In fixed tooth.The seating pad linkage board is fixedly connected by the after-poppet cushion block with the after-poppet pipe.The preceding seating pad
Shaft between the backing plate of recoil is equipped with bounce tongue lock column 21, is equipped with to make bullet outside the bounce tongue lock column on the inside of the bounce tongue lock column
Play tongue spring 22.The traction fiber pulling block is equipped with traction fiber head mounting hole 161 and screw fixed hole 162.The after-poppet pipe
Lower end be equipped with rear wheels 23.The upper end of the front support pipe is equipped with fore-stock cushion block 24, the front side both sides point of the seating pad
It Zhuan Dong not be fixed on the fore-stock cushion block of two front support pipes.
The children trolley link fold mechanism normal use when, i.e. opening state, refering to Fig. 1 and Fig. 9, joint locking at this time
Tooth and seating pad locking teeth are in lock-out state.I.e. knuckle lock fixed tooth is placed in the first seat due to the elastic force half of cushion lock spring
In backing plate lock loose slot, the other half is placed in the second seating pad lock loose slot, preceding seating pad and recoil backing plate is locked, the two nothing
Method relatively rotates.Seating pad locking teeth is another since the elastic force half of cushion lock spring is placed in the first seating pad lock loose slot
It is partly placed in the second seating pad lock loose slot, preceding seating pad and recoil backing plate is locked, the two can not relatively rotate.
When having used children trolley, it is necessary to when carrying out folding operation to vehicle frame, two lock buttons are first pressed, while pull solution
Lock knob, is pressed downward that handle is i.e. foldable, and detailed process is as follows：
First, after pulling unlock knob, unlock knob pulls the first traction fiber, and the first traction fiber drives knuckle lock fixed tooth pressure
Contracting joint locking spring is simultaneously moved fully in the first knuckle lock loose slot, and handle joint and after-poppet joint can be free at this time
It rotates.
Secondly, while knuckle lock fixed tooth unlocks, pushing down on handle joint, stand tube direction rotates backward, and handle closes
The cam groove of section pushes after-poppet sliding shoe stent in-pipe backward, and passes through traction fiber pulling block and drive traction fiber to moving down
Dynamic, traction fiber, which moves down to drive seating pad locking teeth compression cushion lock spring and be moved fully to the first seating pad, locks loose slot
It is interior, seating pad locking teeth, so that preceding seating pad and the unlock of recoil backing plate, can be freely rotated therebetween.
Thirdly, after knuckle lock fixed tooth and seating pad locking teeth unlock, continue to turn folding handle down tube, due to
Handle down tube, front support pipe, curved rod and seating pad form 4 mechanisms, while after-poppet pipe and recoil pad linkage board are formed
Swing rod structure, therefore handle down tube rotates forward, when front support pipe rotates backward, passes through curved rod, recoil pad linkage board band
Dynamic seating pad and after-poppet pipe are folded so that vehicle frame collapses, and referring particularly to Fig. 9-11, the vehicle frame after folding can stand.
It can be seen that children trolley linkage fold mechanism passes through handle down tube, front support pipe, curved rod and seating pad
4 mechanisms are formed, while after-poppet pipe and recoil pad linkage board form swing rod structure, and knuckle lock fixed tooth and seating pad are set
Locking teeth conducts the locking operations respectively to handle joint and after-poppet joint and preceding seating pad and recoil backing plate, not only structure
Succinctly, it is easy to operate, and two lock linkages are set, and seating pad locking teeth could only be unlocked in vehicle frame folding, Bu Huiyin
It is unlocked for maloperation, so as to ensure the security of vehicle frame.
