Quan Xinggao.3. enabling the adjusting height of headrest and shoulder belt height of the growth of the adjoint child of safety seat, and inner width space
Also can synchronization bar two level, be suitable for the build and height of different children, give child's growing space that one comfortable safety is provided.
Mechanism part explanation：
Seat base：Sliding is adjusted in a safety seat part, headrest and the relatively motionless pedestal of flank.
Skeleton on pedestal：It is fixed on seat base, is a part for pedestal, the track as sleeve movement；Lock tube
It is integrally fixed on skeleton.
Sliding sleeve：It can be slided up and down along skeleton；Headrest and flank guide pad are all fixed on sliding sleeve, can follow sliding sleeve
It slides up and down together.
Flank：A safety seat part is used for carrying out lateral protection to child；Because flank guide pad and seat base are oblique
The collective effect of slot.Flank can not only follow sliding sleeve to move up and down together, moreover it is possible to be slided left and right.
Headrest：A part for safety seat, for protecting the head of child；Headrest is fixed on sliding sleeve, can and then be slided
Set slides up and down together.
Adjust knob pedestal：It is fixed on headrest, there is sliding slot on pedestal, acted on by the cylinder of knob, knob can only edge
It and is slided up and down in sliding slot, and limit its row slided up and down.
Adjust knob：Knob pedestal does opposite slide up and down on opposite can resting the head on；As the driving part of external force, drive
Pull rod slides up and down.
Pull rod：And then adjusting knob slides together with knob connection is adjusted；Pass through the cunning on the round pin and lock tongue on pull rod
Slot one works, and drives the flexible of lock tongue.
Lock tongue：Stretching for lock tongue, stretches into or skids off the lock housing on lock tube, carry out the locking and unlock of mechanism.
Latch bolt spring：The pulling force that outside provides disappears, and lock tongue is pushed to be slided toward lock housing direction.
Lockhole on lock tube：Lock tongue stretches into lockhole, and mechanism is just lockked.
Pull rod resetting spring：One is fixed in lock housing, and one is fixed on pull rod, provides the drawing of one, pull rod down
Power.
Flank sliding slot：Flank can be horizontally slipped along fixed flank guide pad, between two flanks of adjusting
Width.
Flank guide pad：It is fixed on sliding sleeve, sliding sleeve can be followed to slide up and down together.
Flank cylinder：Two cylinders on flank, are slided along the skewed slot on seat base.
Seat skewed slot：It is worked by skewed slot on the cylinder and seat base on flank and flank guide pad one, side
The wing can horizontally slip again while sliding up and down.
Operation principle：Headrest is in minimum point, and under the action of latch bolt spring, lock tongue stretches into the lockhole on lock tube always
Interior, mechanism is in the lock state, and headrest cannot be adjusted.
Such as figure, operator up carries knob is adjusted, and drives pull rod up to slide, on the round pin and lock tongue on pull rod
Under skewed slot collective effect, the lock on both sides deviates from the lock housing in lock housing, mechanism is in the unlocked state, at this time head all toward middle slip
Pillow can be adjusted
Structure is in the unlocked state, and operator, which continues to adjust, shakes hands up to carry that height of headrest is transferred to required height；
While rising, under the cylinder collective effect on the skewed slot and flank on seat base, flank passes through on flank headrest
Sliding slot is while rising and along flank guide pad, toward two Slideslips, such flank height also rises, the left and right sides wing
Between width also widen.
Headrest is transferred to required height, and user looses one's grip, and under the action of handle return springs, knob and pull rod are together
It slides down, the thrust provided by skewed slot collective effect on the round pin and lock tongue on pull rod and latch bolt spring, two
Side lock tongue is simultaneously toward movement outside, and lock tongue stretches into the lockhole on lock tube, and mechanism is locked once more, and headrest is also locked out tune
Section.
If headrest needs adjusting height down, action just now is repeated, the unlock of adjusting knob head mechanism is pinched, at this moment pushes
Headrest, headrest can be toward being lowered to required height, while both sides flank is toward middle shrinkage width.Knob is unclamped, in spring
Under the action of oblique mechanism, it is locked that lock tongue stretches into lockhole headrest again.
Therefore, a kind of height of headrest of child safety seat of the utility model is adjusted and flank width adjustment mechanism, knot
Structure is compact, and convenient disassembly further promotes usage safety performance.
