Compared with prior art, the present invention has the following advantages：
1st, perambulator of the present invention promotes forward when folding and pushes handspike, handspike lower end and post upper to
Trailing wheel is close, and rear connecting rod is rotated around itself and back leg link position, and rear connecting rod upper end is also close to trailing wheel, due to rear connecting rod
On be rotatably connected to and slide set, and slide set and be socketed on rear interlocking lever, so when rear connecting rod rotates, slide set and drive
Interlocking lever front end is moved upwards afterwards, and then rear interlocking lever front end interlocks rod rear end before just pulling and moves upwards, so that preceding company
Lever pulls foreleg to be drawn close to back leg, so as to fulfill the folding of whole perambulator.Whole folding procedure is simple, body after folding
Product is small, easy to carry.
2nd, seat support of the invention includes symmetrically arranged a pair of of mounting bar, and mounting rod rear end is rotated with rear connecting rod
Connect, be rotatably connected to sliding sleeve on supporting rod, mounting bar is threaded through in sliding sleeve.So in folding of baby, rear connection
Bar relative to back leg rotate when, rear connecting rod pulls back mounting bar, and mounting bar slides in sliding sleeve, and sliding sleeve is opposite props up
Strut rotates, and is folded together so as to fulfill seat support, operates very convenient quick.
3rd, preceding armrest assembly of the invention includes symmetrically arranged a pair of armrests lower link, handrail lower link lower end and back leg
Rotation connection, handrail lower link upper end are rotatably connected to handrail upper connecting rod, and handrail upper connecting rod upper end is rotatablely connected with supporting rod, and two
Handrail before connection U-shaped in root handrail upper connecting rod.Handrail upper connecting rod, handrail lower link, back leg and supporting rod surround a quadrangle
Quadric chain, in folding of baby, supporting rod and then makes handrail with respect to handrail upper connecting rod is promoted in back leg rotation process
Lower link rotates relative to back leg and handrail lower link is diminished with handrail upper connecting rod angle and fold.So perambulator is when folding
Preceding handrail, operation more simple and fast need not be dismantled.
4th, perambulator of the present invention is in fore-aft fold, and rear connecting rod rotates, rear connecting rod lower end pull slide be sleeved on after connect
Slide in lever, since the front end of the first crossbar and the second crossbar is hinged on the lower end of rear connecting rod, connect later
Bar causes the angle of the first crossbar and the second crossbar to reduce, and perambulator moves toward one another trend in the lateral direction, with this
Meanwhile the rear interlocking lever front end during fore-aft fold can upwarp, therefore interlocking lever 7 pulls left brace and the right side oblique after two
Pull rod, so that left connecting rod and right connecting rod pull two forelegs close on the horizontal direction of left and right, so as to fulfill perambulator on a left side
It is laterally folded in right direction so that volume smaller after folding of baby, it is easily portable.
5th, when perambulator of the present invention is laterally folded in the lateral direction, first connecting rod, second connecting rod, third connecting rod and the 4th
The intersection quadric chain that connecting rod is formed mutually rotates and folds and close up, and ensure that folding of the perambulator in horizontal direction.
6th, the configuration of the present invention is simple, of low cost, folding convenient, volume after folding is small, can be placed on car trunk or fly
In machine luggage carrier, carry very convenient quick.
