Abstract
The utility model discloses a kind of rear wheel of baby carriage group automatic folding mechanisms, including upper support frame, rear support frame, rear wheels, chassis, it is hinged with upper support frame at the top of rear support frame, the first partial gear that the bottom of rear support frame is fixed with, accordingly, the second partial gear being meshed with the first partial gear is fixed on the holder of rear wheels；This end on chassis for connecting rear wheels is T-type connector, and T-type connector side and the cental axial position of the first partial gear are hinged, and the other side of T-type connector and the center axial position of the second partial gear are hinged.Originally practical newly to effectively reduce perambulator whole height, volume is reduced, is convenient for carrying and transports, and cost has no too big difference, more effectively attracts the concern of consumer, thus have the consumption market of bigger, the competitiveness of bigger.
Description
Technical field
The utility model is related to a kind of rear wheel of baby carriage group automatic folding mechanisms, belong to perambulator technical field.
Background technology
To meet practicability and the property easy to carry needed for consumer, children's vehicle carriage generally can all be designed to fold
Construction so that in use state can in the form of flare up carriage for children, without the use of when can then fold into smaller size smaller with
Facilitate collection or carrying.Common perambulator is mainly that unitized frame folds, and rear wheels cannot fold, and cause to fold rear volume
Height, occupied space are big, it has not been convenient to which consumer carries and places.
Invention content
In view of the above-mentioned problems of the prior art, to be to provide a kind of structure design more reasonable for the purpose of this utility model
Rear wheel of baby carriage group automatic folding mechanism, to realize that being folded inward for rear wheels folds.
To achieve the above object, the technical solution adopted in the utility model is：A kind of rear wheel of baby carriage group automatic folding mechanism,
Including upper support frame, rear support frame, rear wheels, chassis, which is characterized in that it is hinged with upper support frame at the top of rear support frame, it is rear to prop up
The first partial gear that the bottom of support is fixed with accordingly is fixed with and the first incomplete tooth on the holder of rear wheels
Take turns the second partial gear being meshed；This end on chassis for connecting rear wheels is T-type connector, T-type connector side
Hinged, the center axle position of the other side of T-type connector and the second partial gear with the cental axial position of the first partial gear
It is hinged to set place.
Preferably, above-mentioned first partial gear 13 is 1/3-1/2 gears；Second partial gear is 1/2 gear.
Compared with prior art, the utility model has the beneficial effects that：Utilize the first partial gear, the second incomplete tooth
Wheel carries out tooth occlusion, drives rear wheels to be folded inward when rear support frame folds.Originally practical newly to effectively reduce the whole height of perambulator
Degree reduces volume, is convenient for carrying and transports, and cost has no too big difference, more effectively attracts the concern of consumer, thus has
The consumption market of bigger, the competitiveness of bigger.

Specific implementation mode
In conjunction with attached drawing, the utility model is further elaborated.
As shown in Figs. 1-5, a kind of rear wheel of baby carriage group automatic folding mechanism of the utility model, including upper support frame 1, rear branch
Support 5, rear wheels 6, chassis 4, upper support frame 1 it is hollow be internally provided with frame locking mechanism, frame locking mechanism includes
Clamping block connecting rod 8, traction rope 9, clamping block 10, resetting spring 11, wherein clamping block connecting rod 8 are fastened on upper support frame 1 and lean on
Nearly top place simultaneously moves up and down, one end of 8 fixed tractive 9 of clamping block connecting rod with respect to upper support frame 1, traction rope 9 it is another
End is fixed on clamping block 10, and the fixed reset spring 11 between clamping block 10 and traction rope 9, and 10 bottom of clamping block is wedge
Shape；It is machined with the lock slots 2.1 to match with 10 wedge-shaped part of clamping block at the top of front support frame 2, under normal operating condition, locking
10 wedge-shaped part of block is caught in lock slots 2.1；2 inside top of front support frame is hinged with 1 bottom of upper support frame；For connecting front wheels
3 and rear wheels 6 chassis 4 and front wheels 3 it is hinged, it is hinged with 2 bottom of front support frame at front wheels 3 on chassis 4；Front support
2 bottom inside of frame is also hinged with link block 12, and link block 12 is hinged with front wheels 3.
This practical new 5 top of rear support frame is hinged with upper support frame 1, and the bottom of rear support frame 5 is to rivet or weld
The first partial gear 13 for being fixed with of mode, the first partial gear 13 is 1/3-1/2 gears, accordingly, in rear wheels 6
Holder on the second partial gear 14 being meshed with the first partial gear 13 is fixed in a manner of riveting or weld,
Two partial gears are 1/2 gear, and 5 bottom of rear support frame passes through by the first partial gear 13,14 structure of the second partial gear
At gear mesh connect with rear wheels 6, on chassis 4 for connect rear wheels 6 this end be T-type connector 4.1, T-type connector
4.1 sides and the cental axial position of the first partial gear 13 are hinged, the other side of T-type connector 4.1 and the second incomplete tooth
The center axial position of wheel 14 is hinged.
This practical new seat frame rear portion and rear support frame are hinged, centre is hinged by connecting rod and upper support frame, front
It is hinged with front support frame.
When folding, when pulling up clamping block connecting rod 8, traction rope 9 pulls clamping block 10, clamping block 10 and lock slots
2.1 disengagement realizes that the unlock of front support frame 2, front support frame 2 rotate inward under the effect of gravity, affects link block 12 inside
Front wheels 3 are affected, realize that front wheels 3 are folded inward；At the same time, the first partial gear of rear support frame rotates counterclockwise,
The second partial gear is driven to rotate clockwise, to drive rear wheels 6 to be folded inward.This practical new handle frame and upper branch
It is rotatably assorted between support, handle frame finally independently carries out rotary folding.
