Can mutually it rotate, i.e., now intermediate active joint 23 is in the lock state；During unblock, by lifting middle pull handle 22, drive and draw
Rope 26 is lifted upwards, and then the dovetail is pulled out from neck 2321, and now intermediate active joint 23 is unlocked, and push rod connects
Socket part 231 can rotate doubling forward, wherein, after the dovetail is pulled out from neck 2321, spring 234 is in compressive state,
When stroller is deployed next time, i.e., push rod connecting portion 231 resets, during the dovetail alignment neck 2321, the elastic force of spring 234
The dovetail is promoted into clamping in neck 2321, intermediate active joint 23 can be locked automatically when realizing stroller expansion.
Further, push rod connecting portion 231 is provided with the first joint axis hole 2311；Front leg strut connecting portion 232 is provided with the
Two joint axis holes 2322；The middle part of fastener 33 offers the axle connection through hole of a bar shaped；Also wrap in the intermediate active joint 23
An arthrodesis bearing pin is included, the arthrodesis bearing pin sequentially passes through the first joint axis hole 2311, the axle connection of fastener 233 is led to
Hole, second joint axis hole 2322, to realize the rotatable of push rod connecting portion 231 and front leg strut connecting portion 232, fastener 233
Motion track restriction etc..
Fig. 5-Fig. 8 is refer to, the upper end of drag-line fixture 25 is provided with a C-shaped elastic buckle 252.Double children push away
When car is in deployed condition (state shown in Fig. 1 is deployed condition), buckle 252 is separated with intermediate push rod fixing pin 213.
The operation principle or unlocked step of go-cart for double child provided in an embodiment of the present invention are as follows：
S1, while press the unblock button of the first locking piece 41 and the second locking piece 42, make first locking device and
The second locking device unblock.State shown in Figure 8.
Pull handle 22 in the middle of S2, lifting, makes the buckle 252 of drag-line fixture 25 block on intermediate push rod fixing pin 213,
Now intermediate active joint 23 is unlocked.State shown in Figure 6.
Now, because the first turning joint 13 and the second turning joint 33 of stroller both sides are not unlocked also, therefore stroller is longitudinal
On will not also fold.
S3, both hands lift the first pull handle 12 and the second pull handle 32 positioned at stroller both sides simultaneously, to unlock the first activity pass
The turning joint 33 of section 13 and second.
Wherein, the first pull handle 12 unlocks the first turning joint 13, and the second pull handle 32 unlocks the mode of the second turning joint 33,
It is similar with structure, the principle in the unblock intermediate active joint 22 of middle pull handle 22, it is by being arranged at the first push rod 10,
The drag-line of the inner chamber of three push rod 30 lifts the fastener of the first turning joint 13, the fastener of the second turning joint 33 realizes unblock behaviour
Make, differing only in the neck of the turning joint of both sides there are two.
Fig. 4 is refer to, it is symmetrical in the front leg strut connecting portion inner chamber of the first turning joint 13 by taking the first turning joint 13 as an example
Provided with two necks, one is to be used to lock the first turning joint 13 during deployed condition, and one is that go-cart for double child is in receipts
During conjunction state, relocking the first turning joint 13 prevents its Automatic-expanding.It will not be repeated here.
S4, go-cart for double child are unlocked comprehensively, are rotated down the first cross bar 411 and the second cross bar 421, are realized double children
The transverse contracting of stroller；Each push rod of doubling, realizes that the longitudinal direction of go-cart for double child is folded forward.Refer to Fig. 9.
Specifically, as shown in Figure 6, Figure 7, Fig. 6, Fig. 7 are the rearview of stroller part-structure.Second cross bar adapter sleeve 423
Rear side it is also raised push away post 4231 provided with a shaped piece being in the form of a column, shaped piece push away post 4231 be arranged in shaped piece 424 in U
In the opening 4241 of shape.
To prevent user's pull handle 22 in the middle of maloperation after ride is folded, cause ride intermediate active joint 23 upon deployment
It can not complete to block during expansion, the boss 221 of middle pull handle 22 can be withstood and can not be completed by the abnormity projection 4243 of different in nature part 424
Fold and block action.
In this step, during transverse contracting is folded, when the second cross bar 421 is folded down, using orientation shown in Fig. 6 as ginseng
Examine, shaped piece pushes away the counterclockwise rotates of post 4231, drive shaped piece to push away post 4231 and push up against shaped piece 424, shaped piece 424
What is be pushed out is rotated clockwise, when the low level step of special-shaped raised 4243 boss 221 for withstanding L-shaped of shaped piece 424 is (convex
The step positioned at downside of platform 221) table top (as shown in Figure 7), shaped piece 424 continue rotate then pressure make boss 221 downward
It is mobile；Boss 221 moves down pull handle 22 in the middle of drive and moved down, and drives buckle 252 from intermediate push rod fixing pin 213
Depart from, spring 234 can push fastener 233 automatically and enter in neck 2321 during in order to deploy.
When returning the vehicle to the garage and knock off, such as operation completes the first step, then has operated after second step, and middle pull handle 22, which is blocked, causes intermediate active to be closed
Section 23 is in released state, if now user is not intended to continue to fold, but starts to complete expansion action again, only need to be by first
The cross bar 421 of cross bar 411 and second is pushed up, and it is locked again by the first locking key 41 and the second locking skill 42, is arranged at the
Boss top 4233 on two cross bar adapter sleeves 423 can push up the high-order step of the boss 221 of L-shaped, and (boss 221 is located at upside
Step), force middle pull handle 22 to move downward, buckle 252 departs from from intermediate push rod fixing pin 213, therefore the first locking
When key 41 and second locks 42 lock-out state of skill, buckle 252 will not be stuck on intermediate push rod fixing pin 213, fastener 233
Neck 2321 can be headed into by spring 234, it is ensured that the lock-out state in intermediate active joint 23.
The expansion process of go-cart for double child is the inverse process for the process that folds, principle and step it is foreseeable that therefore repeating no more.
It is understood that the go-cart for double child of the embodiment of the present invention also includes wheel assembly, bottom bracket, front leg strut
Supporting construction etc..
It is understood that for those of ordinary skill in the art, on the basis of the design of the present invention is learnt, holding very much
It is readily conceivable that the opposite side (side of the first cross bar 411) of middle pull handle 22 is also symmetrically provided with a boss and shaped piece, and first
Shaped piece also is provided with cross bar adapter sleeve 413 and pushes away post, and it should be within the scope of the present invention.
Described above, the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to before
Embodiment is stated the present invention is described in detail, it will be understood by those within the art that：It still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
