92 other side of rotation seat is provided with one and returns the vehicle to the garage and knock off hook 94, is provided in the front foot pipe 4 in collapse state
The lower bayonet lock 43 engaged with the card hole 941 returned the vehicle to the garage and knock off on hook 94.
Above-mentioned first joint 3, the specific structure of second joint 7 and the first tripper 1 and serial verb construction are special referring to China
Sharp Publication No.: the patent of invention of CN204895534U.
In conclusion the hook 94 that will first return the vehicle to the garage and knock off is opened, and is then held hand handle upper tube 1 and is pulled up, baby when the present invention is unfolded
Youngster's vehicle can be automatically performed expansion, 11 automatically lock of the first tripper after expansion, specifically: after the hook 94 that will return the vehicle to the garage and knock off is opened,
During grasping hand handle upper tube 1 and pulling up, hand handle upper tube 1 is opened with respect to hand handle down tube 2, and drives hand handle down tube
2 are swung up around third joint 9, and in the process, hand handle down tube 2 can drive the 7th rotor 93 to rotate, and torsional spring is drawn high
Or compression, make the drive seat frame 8 of wraping plate 91 to lower swing, during seat frame 8 is to lower swing, seat frame 8 can be pushed away
The opposite rear foot tube 5 of dynamic front foot pipe 4 is unfolded, finally after the first tripper 11 locks the first joint 3, at entire baby carriage frame
In unfolded state.
It when the present invention folds, first stirs shifting block 113 and presses unblock button 112, then push 1 upper tube of hand handle under hand handle
Pipe 2 is bent, and subsequent perambulator can be automatically performed and fold, specifically: shifting block 113 is stirred first, and unblock button 112 is unlocked,
It presses unblock button 112 simultaneously to unlock the first joint 3, then hand handle upper tube 1 is pushed to bend to hand handle down tube 2, after bending,
Due to the carrier and the gravity of its own in hand handle upper tube 1 and hand handle down tube 2, hand handle down tube 2 can be automatically downward to rear foot tube 5
It draws close and folds, meanwhile, torsional spring, which generates, resets torsion, increases hand handle down tube 2 to rear foot tube 5 and draws close power, bends hand handle down tube 2
Faster, in the process, hand handle down tube 2 can drive the 7th rotor 93 to rotate, and make wraping plate 91 that seat frame 8 be driven to put upwards
It is dynamic, so that front foot pipe 4 and rear foot tube 5 are quickly drawn close and are folded, during seat frame 8 is swung up, before seat frame 8 will pull
Foot tube 4 is drawn close to rear foot tube 5, is finally stuck in the first rear-wheel 51 and the second rear-wheel 52 in the first front-wheel 41 and the second front-wheel 42
Behind side, the center of gravity of entire perambulator can be in the center of four wheels, make perambulator keep stablizing midstance, then again
The hook 94 that will return the vehicle to the garage and knock off fastens bayonet lock 43, and folding for entire baby carriage frame can be completed.
Certainly, the above is only a specific embodiment of the present invention, be not to limit the scope of the present invention, it is all according to
The equivalent change or modification that structure, feature and principle described in scope of the present invention patent is done should be included in Shen of the present invention
It please be in the scope of the patents.
