【Background technology】
At present, perambulator has turned into the indispensable article in developmental process of child.The perambulator of in the market is general all
Can be folded or be launched, but existing baby carriage skeleton structure is complicated, and volume after folding is still larger.Therefore, Ren Menfei
Often thirst for a kind of easy to use, the simple structure and small perambulator of volume after folding occurs.
【Utility model content】
The utility model purpose is to overcome the deficiencies in the prior art, there is provided a kind of simple structure, easy to operate, after folding
The baby-carrier framework of small volume.
The utility model is achieved through the following technical solutions:

Compared with prior art, the utility model has the following advantages:The utility model baby-carrier framework fold when, forward
Handspike is promoted simultaneously to apply down force to handspike, therefore, the lower end of handspike moved beneath backward drives front rod
The upper end of upper end and rear connecting rod moves downward and is gradually drawn close to Rear frame, and rear connecting rod upper end and front rod upper end are downward
During motion, mounting bar is just slided backward in sliding sleeve, and sliding sleeve is also rotated relative to front rod, on front rod
When end moves downward, the 3rd trace being hinged with it pushes motion by front rod, therefore, the 3rd trace just promotes second
The upper end of trace, then the other end of the second trace just tilt obliquely upward and move, the is pulled during tilting
One trace, so as to draw front frame by the first trace be drawn close to Rear frame, and then completes the folding of whole baby-carrier framework
Folded, whole process passes through the cooperation of a linkage, and folding is smooth, and small volume after the completion of folding, is easy to carry.

【Specific embodiment】
The utility model is further described below in conjunction with the accompanying drawings:
As shown in Figures 1 to 5, a kind of baby-carrier framework, can be moved to folding position from expanded position, including:
Front frame 1, is connected with front-wheel 1a thereon;
Rear frame 2 is connected with trailing wheel 2a thereon, and the upper end of Rear frame 2 rotates with the upper end of front frame 1 and is connected;
Front rod 3, its lower end rotates with the upper end of Rear frame 2 and is connected;
Handspike 4, its middle part rotates with the upper end of front rod 3 and is connected;
Rear connecting rod 5, the lower end of its upper end and handspike 4 rotate be connected, the middle part rotation company of its lower end and Rear frame 2
Connect;
First trace 6, its front end is hinged on the middle part of front frame 1, its rear end and is hinged with the second trace 7, and second
The middle part of trace 7 is hinged on the middle part of Rear frame 2;
Sliding sleeve 8, described sliding sleeve 8 is hinged on the middle part of front rod 3, and be provided with described sliding sleeve 8 can be in it
The mounting bar 9 for sliding, described mounting bar 9 is hinged with the middle part of rear connecting rod 5;
3rd trace 10, its upper end is hinged on front rod 3, and its lower end is hinged on the upper end of the second trace 7.
As shown in Figures 3 to 6, when folding, handspike 4 is promoted forward and down force is applied to handspike 4, because
This, the lower end of handspike 4 moved beneath backward, drive the upper end of the upper end of front rod 3 and rear connecting rod 5 move downward and gradually
Drawn close to Rear frame 2, during the upper end of rear connecting rod 5 and the upper end of front rod 3 move downward, mounting bar 9 is just in sliding sleeve 8
Slide backward, and sliding sleeve 8 is also rotated relative to front rod 3, when the upper end of front rod 3 moves downward, be hinged with it
Three traces 10 push motion by front rod 3, therefore, the 3rd trace 10 just promotes the upper end of the second trace 7, and then the
The other end of two traces 7 is just tilted and moved obliquely upward, the first trace 6 is pulled during tilting, so as to pass through
The traction of first trace 6 front frame 1 is drawn close to Rear frame 2, and then completes the folding of whole baby-carrier framework, and whole process passes through
The cooperation of individual linkage, folding is smooth, and small volume after the completion of folding, is easy to carry.
As shown in Figure 3 to Figure 4, described second trace 7 includes straight bar section 71 and integrally formed with straight bar section 71 curved
Bar segment 72, described knee section 72 is hinged with the first trace 6, and the middle part of described straight bar section 71 is hinged in Rear frame 2,
And the upper end of straight bar section 71 is hinged on the lower end of the 3rd trace 10.Second trace 7 is by straight bar section 71 and knee section
72 composition, therefore, the 3rd trace 10 promote straight bar section 71 when, it is only necessary to very short movement travel can just make knee section 72 to
It is preceding tilting and pass through the position that front frame 1 is drawn to the first trace 6 folding.Therefore, being so designed that can cause whole baby
Youngster's car skeleton structure is more compact.
As shown in Figures 3 to 5, the second described trace 7, rear connecting rod 5 are coaxially hinged with the three of Rear frame 2, described
Sliding sleeve 8, the 3rd trace 10 is coaxially hinged with the three of front rod 3.Therefore, it is possible to as far as possible reduce on parts punching and
The quantity of jointed shaft is installed, makes structure simpler, manufacture is also more convenient, and baby-carrier framework can be made more attractive.
As shown in Figures 3 to 5, described Rear frame 2 includes rear car bar 21, and described rear car bar 21 is provided with to its both sides
First articulated section 22 and the second articulated section 23 of protrusion, described front frame 1 is hinged on the first articulated section 22, it is described before connect
Extension bar 3 is hinged in second connecting portion 23.Due to the both sides of the first articulated section 22 and the second articulated section 23 car bar 21 respectively backward
Protrusion, thus baby-carrier framework when, front frame 1 is drawn close and almost parallel with Rear frame 2 to Rear frame 2, at the same time, preceding company
Extension bar 3 is drawn close and almost parallel with Rear frame 2 to Rear frame 2.Therefore, space is make use of as much as possible, it is ensured that baby-carrier framework
Occupied little space after folding.
As shown in Figure 1 to Figure 3, described baby-carrier framework also includes hand-pushing handle 11, and described hand-pushing handle 11 includes handle
111 and the handlebar stem 112 that is connected on handle 111 and can up and down be slided in handspike 4.Launch shape when baby-carrier framework is in
During state, handlebar stem 112 stretches out from handspike 4, is easy to user to promote perambulator, when perambulator needs to fold, by handlebar stem
112 are retracted into handspike 4 so that the volume compact after folding.
