the hinged part of the front wheel bracket and the rear wheel bracket is a second hinged part, and a seat rod and a support rod are connected to the second hinged part;

the front end of the middle connecting rod is hinged with the first connecting rod, a rod body close to the front end is hinged with the top end of the rear wheel bracket, the middle part is hinged with the seat rod through the second connecting rod, the rear end is hinged with the first hinge part, and a first reinforcing supporting rod is arranged between the middle connecting rods;

the rear end of the first hinge element is also connected with an upper push rod;

universal wheels are connected between the front wheel brackets through pedals;

the rear wheel bracket is connected with a rear wheel through a connecting cross rod.

Furthermore, a second reinforcing support rod is arranged between the rear wheel brackets.

Furthermore, the middle part of the supporting rod is hinged with a T-shaped handrail.

Furthermore, a locking adjusting button is arranged on the upper push rod.

Further, the outer edge side of the seat rod is hinged with an extension fastener.

Further, the first hinge member is also hinged with a canopy rod.

To sum up, the utility model discloses possess following advantage:

the utility model discloses the push rod can be folded, whole folding simple convenient, folding back is small, portable to thereby can not external operation stability height because of folding button.

And, cushion outside of tubes edge side is equipped with epitaxial fastener, can realize the multi-functional use of sitting and lying of baby's shallow.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a three-folding baby stroller is shown in figures 1-3 and comprises a first four-bar linkage structure formed by hinging a first hinge joint 1, a lower push rod 2, a middle connecting bar 3 and a rear wheel bracket 4 which are symmetrically arranged.

The device also comprises a second four-bar linkage structure formed by hinging a front wheel bracket 5, a first connecting bar 6, a rear wheel bracket 4 and a middle connecting bar 3 which are symmetrically arranged;

specifically, a second hinge part 7 is arranged at the hinge joint of the front wheel bracket 5 and the rear wheel bracket 4, and a seat rod 8 and a support rod 9 are connected to the second hinge part 7;

continuing to refer to fig. 1, the front end of the middle connecting rod 3 is hinged with the first connecting rod 6, the rod body near the front end is hinged with the top end of the rear wheel bracket 4, the middle part is hinged with the seat rod 8 through the second connecting rod 10, and the rear end is hinged with the first hinge part 1.

A first reinforcing support rod 15 is arranged between the middle connecting rods 3, so that the structure of the whole baby carriage is more stable;

the rear end of the first hinge part 1 is also connected with an upper push rod 11, and the upper push rod 11 is provided with a locking adjusting button for controlling whether the baby carriage is folded or not.

18 during use, the user pushes the push-up rod 11 to push the stroller.

Universal wheels 13 are connected between the front wheel brackets 5 through pedals 12.

The rear wheel bracket 4 is connected with a rear wheel 41 through a connecting cross bar 14.

And a second reinforcing support bar 16 is also provided between the rear wheel brackets 4.

With further reference to fig. 1, in its unfolded state, the support bar 9 is hinged in its middle with a T-shaped grab bar 17, which grab bar 17 is folded inwards in its folded state.

Further, the outer edge side of the seat rod 8 is hinged with an extension fastener 81, so that the multifunctional use of sitting and lying of the baby stroller can be realized.

Preferably, the first articulation 1 is also articulated with a canopy rod 19.

Of course, as the bottom of the rod can be provided with a telescopic pull rod, the telescopic pull rod is more convenient to fold and use during travel, and the telescopic pull rod does not need to be carried by hand constantly in a folded state.

The folding process is further explained in connection with:

firstly, the T-shaped handrail 17 is buckled inwards to the seat, the locking adjusting button 18 is pressed, the upper push rod is pressed downwards, at the moment, the first four-bar linkage structure acts, the front end of the middle connecting rod is lifted upwards, and the rear end of the middle connecting rod is pressed downwards.

Therefore, the second four-bar linkage structure is driven to act, the front wheel bracket contracts towards the rear end and is in parallel folding motion with the rear wheel bracket.

At this time, the seat lever also performs this folding motion by the second connecting rod.

And the upper push rod can fold towards the front end and the lower end under the action of the first hinge.

Therefore, the whole baby carriage forms three folding in the folding process, and the folded baby carriage is smaller in size and more convenient to carry.
