On front wheel carrier, left and right handrail is linked together with left and right rear wheel bar, and handspike intersects with left and right rear wheel bar and connect, cushion
It is hinged in the handrail of left and right, protection lasso is connected in the handrail of left and right, handspike is telescopic rod；Handspike and a left side when use
Off hind wheel bar intersection struts, and cushion is fixed on handspike by latching device；It carries and unlocks latching device, cushion when collecting
It digs upwards, handspike closes up with the folding of left and right rear wheel bar.The structure folds simply, easy for operation, preceding after vehicle folds
The size of rear direction has larger diminution, but height can not become smaller, therefore still there is a problem of that volume after folding is larger, can not
Packaging volume is fundamentally reduced, journey carries still inconvenient.In view of the above-mentioned problems, many manufacturers and knowledgeable people into
Row exploitation and development, but do not there is relatively satisfactory product to come out so far.
Summary of the invention
In order to overcome above-mentioned defect of the existing technology, the purpose of the invention is to provide a kind of structure and simply closes
Reason, easy for operation, firm and reliable connection, folding volume be small, uniaxial folding type baby carriage easy to carry and collection.
The invention solves technical solution used by above-mentioned technical problem, it includes left and right handrail, front wheel carrier, preceding
Wheel, left and right rear wheel bar, rear-wheel, handspike, cushion, cradle head component, the cradle head component include passing through fixing axle
It is successively symmetricly set on the left and right handrail bar joint, left and right front-wheel bar joint, left and right rear-wheel bar joint of push rod joint two sides, left and right
Handrail correspondence is fixed on the handrail bar joint of left and right, and front wheel carrier correspondence is fixed on the front-wheel bar joint of left and right, left and right rear wheel bar
Correspondence is fixed on the rear-wheel bar joint of left and right, and handspike is fixed on push rod joint；Left and right handrail bar joint is pushed away with corresponding
The handrail limited block and push rod sliding slot of angle between control left and right handrail and handspike, left and right are correspondingly provided between bar joint
The front wheel bar of control left and right handrail folding angles is correspondingly provided between front-wheel bar joint and corresponding left and right handrail bar joint
Sliding slot and handrail limited block are correspondingly provided with control left and right between left and right rear-wheel bar joint and corresponding left and right front-wheel bar joint
The rear wheel bar sliding slot and front wheel bar limited block of angle between rear wheel bar and front wheel carrier.
The further scheme of the invention, the cushion is hinged in the handrail of left and right, between cushion and handspike
Equipped with latching device, the latching device include the fixed lock being fixed on cushion, be arranged on handspike and with fixation
The elastic Button Block matched is latched, cushion down tilt when expansion uses or so in handrail simultaneously makes fixation snap onto elastic buckles
On seat.
The further scheme of the invention is equipped with locking machine between the left or right front-wheel bar joint and push rod joint
Structure, the locking mechanism include the socket being arranged on left or right front-wheel bar joint, the elasticity being arranged on socket insert
Pin, when expansion uses in the lockhole in resilient pin insertion push rod joint, prevent left and right front-wheel bar joint and push rod joint locking from
Rotation.
The further scheme of the invention is connected with turnover protection lasso in the left and right handrail.
The further scheme of the invention is fixed with foot pedal on the front wheel carrier, is at least arranged one on front wheel carrier
A front-wheel, rear-wheel are rotationally correspondingly arranged in the rear wheel bar of left and right.
The further scheme of the invention, the handspike are the telescopic rod of adjustable length, are consolidated on handspike
Surely there is hand-pushing handle.
After adopting the above structure, it has the following advantages compared with the prior art and effect: first is that being first released from lock when folding
Mechanism, the spanner for pulling elastic Button Block separate the fixed lock of cushion with elastic Button Block, and the mechanism that then unlocks is dialled outward
Resilient pin out separates resilient pin and the lockhole in push rod joint, and left and right handrail and handspike are folded towards front wheel carrier, most
After close up front wheel carrier and left and right rear wheel bar, that is, can reach the purpose of folding, folding rate is fast.Second is that due to left and right handrail, hand
Push rod, front wheel carrier, left and right rear wheel bar are connected to cradle head component, so folded height is low, packaging volume is small, carries and receive
Hiding is convenient, solves the problems, such as that existing foldable baby trolley fold height is high.Third is that strutting in use, due to front wheel carrier joint
Locking mechanism is equipped between push rod joint, resilient pin is inserted into the lockhole in push rod joint, makes left and right front-wheel bar joint and push away
Bar joint locking cannot be rotated mutually, it is ensured that stable connection is reliable when use, it is ensured that using safe.
