Specific embodiment

The embodiment of the utility model is described further below in conjunction with the accompanying drawings.

A kind of specific embodiment of baby carriage frame of the utility model, as Figure 1-Figure 4, wherein 1 is foreleg, 2 are Back leg, 3 be hand push frame, and 4 be hand-pushing handle, and 5 be supporting rod, and 6 be drive link, and 7 be interlocking lever, and 8 be mounting, and 9 draw for mounting Bar, 10 be T shape handrails, and 11 be articulation piece, and 111 be flat segments, and 112 be bending segment, and 12 be support wheel, 13 foot frames, before 14 are Fork, 15 be front-wheel, and 16 be trailing wheel, and 17 be mounting bracket, and A is the first hinge joint, and B is the second hinge joint, and C is third hinge joint.

The upper end of hand push frame 3 and the end of hand-pushing handle 4 are rotatablely connected by articulation piece 11, and articulation piece includes flat segments 111, One end of flat segments 11 is fixedly connected on the end of hand-pushing handle 4, and the other end of flat segments 11 bends downward to form bending segment 112. The lower end of hand push frame is coaxial hinged with the upper end of foreleg 1 and the upper end of back leg 2 and forms the first hinge joint A, foreleg 1 in hinged place Lower end connection front fork 14, front-wheel 15, the lower end connection trailing wheel 16 of back leg 2 are installed on front fork.

Supporting rod 5 is equipped between hand push frame 3 and back leg 2, the upper end of supporting rod 5 and bending segment 112 are hinged, supporting rod 5 Lower end is equipped with L-shaped drive link 6, and the lower end of drive link 6 and supporting rod 5 and back leg 2 are coaxial hingedly and in hinged place formation the Two hinge joint B, the corner of drive link 6 and the rear end of interlocking lever 7 are hinged, and the foreleg 1 and foreleg 2 of interlocking lever 7 are hinged.

8 hinged support of mounting forms third hinge joint C on hand push frame 3 and in hinged place, and mounting 8 passes through mounting draw bar 9 realize the drive connection between supporting rod 5, and 9 upper end of mounting draw bar is hinged with mounting 8, the lower end of mounting draw bar 9 and branch Strut 5 is hinged, and upper end of the mounting 8 also with drive link 6 is hinged, to realize the drive connection between mounting 8 and foreleg 1 and back leg 2.

The front end of mounting 8 is equipped with T shapes handrail 10, and T shapes handrail 10 can be rotated towards the seat face of seat 8, when stroller bone When frame folds, T shapes handrail 10 is rotated towards the seat face of mounting 8, is realized folding to be drawn close with mounting 8, is overcome traditional baby Youngster's cart skeleton needs to dismantle handrail defect when folding, and makes user's operation simpler faster.

The support wheel 12 that ground is used to support after baby carriage frame folds is connected on bending segment 112, since baby pushes away Trailing wheel 16 also supports ground after vehicle folds, so the baby carriage frame after folding passes through support wheel 12 and trailing wheel 16 and ground It supports and stands on the ground, go in this way convenient for carrying out or drawing.

The front end of mounting 8 sets the adjustable foot frame 13 of rotate to it and rotational angle, and foot frame 13 not only meets The comfort that baby takes, while mounting 8 can also be extended in perambulator length in the front-back direction, when baby needs to lie down, Foot frame 13 can be turned to horizontal position.

The operation principle and the course of work of the utility model：Baby carriage frame need fold when, hold hand-pushing handle 4 and to Upper lifting, hand-pushing handle 4 rotate relative to hand push frame 3 and it are made to be drawn close to hand push frame 3, and simultaneously, hand push frame 3 and supporting rod 5 divide It is not rotated around the first hinge joint A and the second hinge joint B relative to back leg 2, supporting rod 5 passes through mounting draw bar 9 in rotation process Mounting 8 is driven to be rotated around third hinge joint C, mounting 8 drives foreleg 1 with after in rotation process by drive link 6 and interlocking lever 7 Leg 2 is rotated to the direction mutually drawn close, the final folded in three for realizing baby carriage frame, small after folding, structure letter It is single, it occupies little space, it is easy to carry, it can be placed on the luggage carrier above the boot or aircraft seat of automobile, and stroller The structure of skeleton is simple, and it is flexible to fold folding.
