[specific embodiment]
It elaborates with reference to the accompanying drawing to the embodiments of the present invention.
As shown in Figures 1 to 9, a kind of folding device of perambulator, the first supporting leg 1 and transverse direction including being connected with wheel
Lateral shaft 2 on first supporting leg 1 is set, the first turning set 3 that can be rotated to it, institute are connected on the lateral shaft 2
It states and is connected with the second supporting leg 4 on the first turning set 3,4 lower end of the second supporting leg is connected with wheel, and first supporting leg 1 is logical
It crosses the fixing sleeve 5 being disposed thereon to be fixedly connected with lateral shaft 2, be arranged between the fixing sleeve 5 and the first turning set 3 limited
The locking device for making the rotation of the first turning set 3 on the lateral shaft 2 and is located at the side of fixing sleeve 5 be also connected with can be opposite
Its second turning set 6 rotated is connected with support rod 10, second turning set 6 and fixing sleeve on second turning set 6
The driving device that locking device can be driven to unlock after the rotation of the second turning set 6 is provided between 5.
Perambulator fold when, first manipulation support rod rotate the second turning set, by driving device release fixing sleeve with
Locking limitation between first turning set, enables the relatively transverse axis of the first turning set to rotate, need to only be lifted up transverse direction at this time
Axis, fixing sleeve and the first supporting leg are fixed, and the second supporting leg can be drawn close to the first supporting leg direction, to realize entire
The folding of perambulator；I.e. front wheel supporting leg is drawn close to rear-wheel supporting leg direction, because front wheel supporting leg light structure, light-weight,
When lifting lateral shaft, front wheel supporting leg is easy to rotate to rear-wheel supporting leg direction, and entire stroller configuration is simple, Foldable square
Just easy to carry, it can be achieved that single-hand folding, volume after folding is small.
As shown in Figures 1 to 9, in the present embodiment, the locking device includes to be arranged in the first turning set 3 simultaneously
It can be offered in the first sliding block 7 of the first turning set 3 axial movement, the fixing sleeve 5 for the insertion of 7 one end of the first sliding block
And then the limiting slot 51 of the first turning set 3 rotation is limited, it is provided between first sliding block 7 and the first turning set 3 in baby
Can make the first spring 9 that the first sliding block 7 is maintained in limiting slot 51 under car exhibition open state, it can be achieved that the second supporting leg automatic clamping
It closes.
As shown in Figures 1 to 9, in the present embodiment, the driving device includes that simultaneously energy edge is arranged in fixing sleeve 5
The second sliding block 8 that fixing sleeve 5 is axially moved, being provided on second turning set 6 can be for the slotting of 8 one end of the second sliding block insertion
Slot 61, the end of second sliding block 8 are in cambered surface, and the slot 61 has the cambered surface to match with 8 end of the second sliding block
Groove；One end of second sliding block 8 and the first sliding block 7 are pressed against each other so that the other end of the second sliding block 8 is maintained in slot 61.
The second turning set is rotated, slot 61 drives the second sliding block to another end motion, and then presses the first sliding block, makes the first sliding block from limit
It skids off, lifts restrictions in the slot of position.
As shown in Figures 1 to 9, in the present embodiment, be provided in the support rod 10 can in it up and down slide and
The handspike 11 that the second turning set 6 can be driven to rotate after glide downwards.Being provided between second turning set and lateral shaft can prevent
The locking system of second turning set rotation can be in handspike glide downwards rear-guard by being provided with handspike in support rod
Dynamic locking system unlock, and then drive the rotation of the second turning set.
Specifically, as shown in fig. 6, be equipped in the lateral shaft 2 can locking pin 21 that transversely axis 2 radially slides, it is described
It is provided with the lock slots 62 that can be inserted into for locking pin 21 in second turning set 6, is also set between the locking pin 21 and lateral shaft 2
There is the second spring 22 that locking pin 21 can be made to be maintained in lock slots 62 in perambulator expansion, when handspike 11 is slided to support
When 10 lower end of bar, locking pin 21 is driven to be detached from lock slots 62, so that the relatively transverse axis 2 of the second turning set 6 rotates；
The utility model perambulator is when folding, promotion handspike glide downwards in support rod first, under handspike
End touches locking pin and releases locking pin out of lock slots on the second turning set, at this time the cambered surface groove of handspike lower end
Surrounded with the inner wall of the second turning set it is arc-shaped so that the second turning set being capable of the rotation of relatively transverse axis, support rod and hand
Push rod also just rotates and draws close folding to the first supporting leg, the slot meeting after the rotation of the second turning set, on the second turning set
The second slide block movement is driven, and then the first sliding block is pushed to be detached from limiting slot, so that the relatively transverse axis rotation of the first turning set, so
After support rod is drawn close to the first supporting leg, it only need to be lifted up lateral shaft, the second supporting leg can be drawn close to the first supporting leg,
To realize the folding of entire perambulator.Entire stroller configuration is simple, and folding convenient, volume after folding is small, easy to carry.
As shown in Figures 1 to 9, in the present embodiment, limit hole is equipped with along its circumferential direction on first turning set 3
31, the lateral shaft 2 is equipped with the protrusion post 23 for penetrating limit hole 31.So that the first turning set can only move in the circumferential direction, no
Radial motion can be generated, guarantees the stability of rotation.
As shown in Figures 1 to 9, in the present embodiment, it is provided with through-hole 52 on the fixing sleeve 5, fixing sleeve 5 passes through setting
Screw in through-hole 52 is fixedly connected with lateral shaft 2.It is lifted up lateral shaft, the first supporting leg being connected on fixing sleeve 5
Fixed, the second supporting leg connecting with the first turning set is drawn close to the first supporting leg direction, due to the company of the second supporting leg
Socket part position is less, and opposite first supporting leg is light and handy, so rotation flexibly, is returned the vehicle to the garage and knock off conveniently, it can be achieved that single-hand folding.
Working principle:
When needing to be unfolded perambulator, rotary supporting rod 10 makes it away from the first supporting leg, and locking pin 21 is inserted into lock slots
62, realize the engaging of the second turning set, then the second supporting leg is moved to the direction far from the first supporting leg, i.e. the first turning set
It is rotated on lateral shaft, when the first sliding block on the first turning set snaps onto it on fixing sleeve by the active force of the first spring
Limiting slot when, it can be achieved that the second supporting leg (front wheel supporting leg) automatic fastening, realize the expansion of vehicle, it is easy to operate.
