Backing plate both sides, lock tongue locks respectively in the both sides of the recoil backing plate of vehicle frame, while between the front and back seating pad of vehicle frame after two
Lock tongue spring column is inserted into unlock head cover, will be sat pocket both sides and be locked respectively by three positions, and be formed with vehicle frame after locking
One, firm stable.
It when using pocket is sat, such as needs to adjust backing tube backward, is such as adjusted to semi-lying state from the sitting state for sitting pocket, or
When adjusting from semi-lying state to lying status, hand pinches upper lock tongue knob 6, and upper lock tongue 7, upper lock tongue 7 are pulled by the first traction fiber
It squeezes upper lock tongue spring and is retracted in backing tube, to make upper lock tongue unlock, backing tube rotating backward can carry out at this time
Gear is adjusted.It when needing forward to adjust backing tube, such as adjusts to semi-lying state from lying status, or is adjusted from semi-lying state
When to sitting state, it is only necessary to backing tube is pushed forward, because the shelves tooth upper side of backing tube is set as arcwall face, downside
Face is to face directly, therefore when backing tube pushes forward, upper lock tongue is made to be slided on the arcwall face of shelves tooth and compress upper lock tongue spring,
And upper lock tongue is finally made to slide into next gear.
When if you need to which pocket and vehicle frame dismounting will be sat, pulling unlock knob 13, before unlock shakes hands 13 by the drive of the second traction fiber
Lock tongue 11 moves backward, and preceding lock tongue is retracted unlock out of preceding seating pad of the vehicle frame, while preceding lock tongue 11 moves backward, its tiltedly
Slanted kicking block 10 is jacked up under the action of sliding surface, slanted kicking block 10 forces unlock head cover 12 to move out, will when unlock head cover moves out
Bounce tongue lock column on vehicle frame is ejected out of cushion posterior joint, to sit pocket unlock, can will be sat pocket at this time and be disassembled from vehicle frame.
When pocket is sat in installation, the recoil backing plate locking for sitting the rear lock tongue insertion vehicle frame on pocket posterior joint is fixed, while vehicle frame two
Bounce tongue lock column 100 between seating pad squeezes unlock head cover, and stretches into intra-articular locking before seat pocket, and unlock head cover squeezes oblique simultaneously
Jacking block, it is intra-articular before so that slanted kicking block is entirely retracted to seat pocket, the preceding joint of pocket is sat at this time and seat pocket posterior joint is in the unlocked state, preceding lock
Tongue is protruding under the action of the spring, and preceding lock tongue stretches into locking in the preceding seating pad of vehicle frame.
When vehicle frame folding, sit pocket can be folded with vehicle frame, the preceding seating pad of vehicle frame forward and recoil pad backward
It turns folding respectively, and drives to sit the preceding joint of pocket and sit pocket posterior joint and be turned out folding respectively, sit the convex of the preceding joint of pocket at this time
Race pushes the tooth boss of backrest gear teeth, and backrest gear teeth squeezes gear teeth resetting spring and to close to seat pocket posterior joint direction
Movement, to make the upper lock tongue of backing tube slide into the arc neutral gear area of backrest gear teeth, backing tube can freely swing at this time, lean on
Penstock unlocks, and folds under gravity, armrest seat also folds under gravity.
When seat pocket is folded with vehicle frame, sits the preceding joint of pocket and seat pocket posterior joint mutually turns rotating around rotation axis of its connection
Dynamic, the limited post of armrest seat both sides is located in its limiting slot, and limiting slot drives limited post rotation, when vehicle frame is opened completely
When, armrest seat is also for normal operating condition.
In addition, the children trolley is sat in pocket fold mechanism, sitting pocket front and back can exchange placement.It sits pocket and exchanges placement, be convenient for
When carrying out, mother can be face-to-face with baby, and baby sees mother at any time, and baby's mood can be pacified at any time by also allowing for mother.
It can be seen that the children trolley sit pocket fold mechanism by sit the preceding joint of pocket and sit pocket posterior joint on preceding lock tongue and
Lock tongue and the corresponding bounce tongue lock column of unlock head cover form corresponding 3 locking structures in the left and right sides with vehicle frame respectively afterwards, 3 points
The triangular structure that locking structure is formed is more solid and reliable, can not only be connected with vehicle frame, but also can be shaken hands by unlocking
The 3 locking structures unlock that can be achieved with sitting pocket, has simple for structure, simple operation and other advantages.Simultaneously sit pocket can realize it is flat
Lie, semi-lying and three kinds of gears of sitting are switched fast, when adjusting gear backward, need to realize by upper lock tongue knob and adjust,
Can prevent maloperation, more securely and reliably, and forward regulation stall when, it is only necessary to forward push backing tube can be realized, it is non-
Normal convenient and hommization.
