It is conllinear to set.
In the present embodiment, specifically, front support rod connector 1b has the connection sheet of two plate-likes, two plate-like connection sheets
Between there is spacing and form the slot for push rod connector 3a insertions, push rod connector 3a is ordinatedly plugged in front support rod connector 1b
Slot in and both axis line locations pass through 11 phase pivot of first axle connect.In this way, when the mistake with folding is unfolded in stroller frame
Cheng Zhong, push rod 3 around first axle 11 relative to front support rod 1 rotate when, push rod connector 3a is plugged in the slot of front support rod connector 1b all the time
In.
Referring to shown in each attached drawing, the vallecular cavity of slot is connected with the rod cavity of front support rod 1 on front support rod connector 1b, connecting rod 6
Upper end is stretched into the vallecular cavity of slot and is connected by the 3rd axis 13 with push rod connector 3a phase pivots.Also insert the upper end of strut 4
Enter in the vallecular cavity of above-mentioned slot and be connected by the second axis 12 with push rod connector 3a phase pivots, the second axis 12 sets up separately with the 3rd axis 13
In the radially different both sides of first axle 11；The bottom of strut 4 is then pivotally connected on back stay 2 by the 5th axis 15.
This causes the structure that the upper end of the upper end of connecting rod 6, strut 4 is rotatablely connected with push rod 3 to be respectively respectively positioned in slot, can avoid
Produce and squeeze folder, while also so that the appearance of stroller frame seems more simple and beautiful.
Referring to shown in Fig. 1, Fig. 4, cross bar component includes front rail 101, the connection being connected between 1 lower part of both sides front support rod
Rear transverse rod 201 between 2 lower part of both sides back stay, and the cross tube 301 being connected between 3 top of both sides push rod, both sides
Push rod 3 and cross tube 301 can be integrally formed and be in downward opening U-shaped, the back stay 2 and strut 4 of both sides are along right and left
To being respectively positioned between the front support rod 1 of both sides.Wheel assembly includes being divided into two front-wheels 20 of 1 lower part of both sides front support rod, is divided into
Two trailing wheels 30 of 2 lower part of both sides back stay.Locking mechanism, which can be arranged between the top of front support rod 1 and the lower part of push rod 3, to be used for
Both are locked, so that per each rod piece/component mutually locking on side side stand 10, and then stroller frame can be locked
In the deployed state.
Referring to shown in Fig. 1 to Fig. 3, when stroller frame is locked in unfolded state, sliding block 5 is fully housed in connecting rod 6
In the rod cavity of front support rod 1, this several front support rod 1, back stay 2, push rod 3 and rear pole 4 rod pieces are can be only seen from outside, and often
On the side stand 10 of side, front support rod 1 extends with push rod 3 along same length direction, front support rod 1, back stay 2, push rod 3 and strut 4
Between constitute stable triangular structure.The children trolley overall appearance seems very succinct, and aesthetics is higher, and whole
The stability of car is good.The outside of push rod 3 and front support rod 1 there is no the rod piece or component of activity, be more convenient for outside children trolley
The problems such as enclosing the setting and installation of component, interference will not be produced in stroller frame expansion and during folding.
When needing to fold up the stroller frame, referring to shown in Fig. 4 to Fig. 6, after locking mechanism is unlocked, push
Push rod 3 makes it turn over around first axle 11 with respect to front support rod 1, the push rod connector 3a of 3 lower part of push rod rotate around first axle 11 and
So that the upper end of connecting rod 6 is moved upwards, so that 6 uplink of connecting rod and pull sliding block 5 gradually to be moved upwards along front support rod 1,
4 downlink of strut and promoting back stay 2 at the same time so that back stay 2 is rotated relative to front support rod 1 and relatively gradual front support rod 1 is collapsed, into
And gradually to collapse between front support rod 1, back stay 2 and strut 4.Finally, the front support rod 1 of stroller frame homonymy, back stay 2,
Strut 4 and push rod collapse together, and front-wheel 20 is drawn close along the longitudinal direction with trailing wheel 30, and stroller frame can rely on the front-wheel 20 of both sides
With trailing wheel 30 from ground is stood on, as shown in Figure 7, Figure 8, its occupied space is smaller, also allows for the daily storage of user with carrying.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
