Specific embodiment
Referring to Fig. 1 to Figure 11, this example provides a kind of folding children's barrow, and it is included with deployed condition and folded state
Trolley rack, one group of front component 1 and two groups of wheel assemblies 2, the locking mechanisms for trolley rack to be locked in deployed condition.
Trolley rack includes the side stand 3 for being located at both sides, the cross frame being arranged between the side stand 3 of both sides.Side stand 3 enters
One step includes that the upper end of front-wheel support 30, bottom and front-wheel support 30 rotates the push rod 31, upper end and front-wheel of connection
The upper end of support 30 rotate connection rear wheel support 32, be arranged on the handle 33 of the upper end of push rod 31.Positioned at the institute of both sides
The non-parallel setting of front-wheel support 30 is stated, it is substantially big in upper end distance therebetween, and lower end is therebetween apart from little arc
Arrange, positioned at the also non-parallel setting of push rod 31 of both sides, substantially in lower end, therebetween distance is big for it, upper end distance therebetween
Little arc is arranged.Front component 1 include front-wheel 10, front-wheel joint 11, the front-wheel joint 11 include two ends respectively with both sides
The bottom of front-wheel support 30 rotates the front-wheel support connector 110 of connection.Further, the bottom of front-wheel support 30 has
First inclined-plane A, the both ends of front-wheel support connector 110 have respectively the second inclined-plane B coordinated with the first inclined-plane A, front-wheel
The bottom of frame 30 is with the both ends of front-wheel support connector 110 respectively by first through the first inclined-plane A and the second inclined-plane B
Pivot a rotates connection, the first inclined-plane A and the second inclined-plane B and the mutual out of plumb of the first pivot a, between two first inclined-plane A or two
It is in bottom-up outwardly state between second inclined-plane B.The upper end of front-wheel support 30 is fixed with joint 300, and this connects
300 have the 3rd inclined-plane C, and the upper end of rear wheel support 32 has the 4th inclined-plane D coordinated with the 3rd inclined-plane C, rear wheel support 32
Upper end and joint 300 rotated by the second pivot b through the 3rd inclined-plane C and the 4th inclined-plane D and be connected, the 3rd inclined-plane C
It is in the state inwardly drawn in from bottom to top between two the 3rd inclined-plane C with the 4th inclined-plane D and the mutual out of plumb of the second pivot b.It is described
The setting on two groups of inclined-planes can be caused when folding, the front-wheel support 30 of both sides, and rear wheel support 32 is laterally inward relative gathering,
So as to reduce lateral dimension.Additionally, joint 300 can also have the 5th inclined-plane, the lower end of push rod 31 has matches somebody with somebody with the 5th inclined-plane
The 6th inclined-plane for closing, bottom and the joint 300 of push rod 31 are turned by the 3rd pivot c phases through the 5th inclined-plane and the 6th inclined-plane
Dynamic connection.
Trolley rack also includes that leading section is rotated with front-wheel joint 11 by horizontally extending horizontal pivot 4a and connects
The bottom supporting rod 4 for connecing.Cross frame include being arranged between the rear wheel support 32 of both sides and can horizontal folding rear cross member 5, bottom supporting rod 4
Rearward end and rear cross member 5 rotate and be connected.
Further, rear cross member 5 includes being located at middle part after go-cart, the vertical connecting rod 50 for vertically extending, from top to bottom
Be successively set on upper connecting base 51 on vertical connecting rod 50, middle connecting seat 52 and lower connecting base 53, inner end respectively with upper connecting base
51 relative to two sides rotate first cross bar 54 and the second cross bar 55 of connection, inner end two sides relative with lower connecting base 53 respectively
Rotate the 3rd cross bar 56 and the 4th cross bar 57 of connection, upper end rotates respectively for connecting with relative two sides of middle connecting seat 52
One brace 58 and the second brace 59, the first cross bar 54, the second cross bar 55, the 3rd cross bar 56 and the equal level of the 4th cross bar 57 set
Put, and their outer end rotates with the rear wheel support 32 of homonymy and is connected, the lower end of the first brace 58 and the second brace 59
Portion rotates and is connected with the 3rd cross bar 56 and the 4th cross bar 57 respectively.It is described to rotate connection by pivoting connection.First
Cross bar 54, the second cross bar 55, the 3rd cross bar 56, the 4th cross bar 57, the first brace 58 and the second brace 59 are arc.Bottom bracing
The rearward end of bar 4 is connected with upper connecting base 51 by horizontally extending pivoting, and is provided with the rear end of bottom supporting rod 4
Handle 6.In addition, being provided with step 9 on lower connecting base 53.
Further, cross frame also includes the push rod stull 7 being arranged between the push rod 31 of both sides, and the push rod stull 7 is wrapped
Include one end to rotate first singletree 70 and the second singletree 71 of connection, the first singletree 70, the second singletree 71 it is another
One end rotates with the upper end of the push rod 31 of both sides be connected respectively.Locking mechanism includes being arranged on the first singletree 70 and the
It is used for the lock cell 8 of the two relative locking between two singletrees 71.
This example children trolley folding process is as follows：
The first step：Lock cell 8 at push rod stull 7 is unlocked, is then forward overturn the entirety of push rod 31, such as Fig. 6 and 7
It is shown, draw close completely with front-wheel support 30 to push rod 31；
Second step：Referring to Fig. 7, handle 6 is lifted up, bottom supporting rod 4 rotates around horizontal pivot 4a, while pulling front-wheel
Joint 11 to the direction of rear wheel support 32 rotates, and the first inclined-plane A is rotated relative to the second inclined-plane B, and the front-wheel support 30 for making both sides exists
Relative gathering is laterally inward while drawing close to the rotation of rear wheel support 32, while handle 6 is pulled up, rear cross member 5 is laterally received
Hold together, the rear wheel support 32 of both sides is driven to middle gathering, simultaneously because matching somebody with somebody by inclined-plane between rear wheel support 32 and joint 300
Close, when rear wheel support 32 forward draw close by wheel support 30, rear wheel support 32 itself is laterally inward phase also relative to front-wheel support 30
To drawing in, finally as shown in FIG. 10 and 11, from figure 10, it is seen that after folding, the front-wheel support and rear wheel support positioned at both sides is equal
Opposed, inwardly directed to have drawn close, rear wheel support 32 and push rod 31 are respectively positioned on the inner side of front-wheel support 30, compared with the volume before folding,
Cart body product is greatly reduced after folding, is easy to pack, transport and carry.
The present embodiment center tap is integrally fixed on front-wheel support, and what push rod and rear wheel support were rotated is connected on joint.
Used as a change programme of the present embodiment, joint is integrally fixed on the bottom of push rod, now, front-wheel support and trailing wheel
Support is rotated with the joint by pivot and is connected.The folding process of this kind of structure is same as the previously described embodiments.
The present invention is described in detail above, its object is to allow the personage for being familiar with this art to will appreciate that this
The content of invention is simultaneously carried out, and can not be limited the scope of the invention with this, all spirit institutes of the invention
The equivalence changes of work or modification, all should cover within the scope of the present invention.
