The specific embodiment

As shown in Figures 1 and 2, the quick folding mechanism of baby stroller of the present utility model, it comprises the preceding framework 10 of a horizontal ㄇ shape, should before the closed end of framework 10 be made as two and articulate mutually and foldable top folded rod (among the figure not label), and be pivoted with a front frame 20 and an after poppet 30 respectively in the both sides of this preceding framework 10, two after poppets 30 stretch out towards the below, two ends of this preceding framework 10, and wheel 21 and back wheel 31 before this front frame 20 and after poppet 30 bottoms are separately installed with, and two front frames 20 are pivoted with the two mutual end folded rods 22 that link that articulate between wheel 21 tops before two, and are pivoted with a linkage rod group 40 between two front frames 20 and two after poppets 30.

Can consult Fig. 3, shown in Figure 4 simultaneously, this linkage rod group 40 is contained in two front frames 20 and 30 of two after poppets are respectively equipped with one or two last folded rod that is pivoted mutually 41 and following folded rod 42, and folded rod 41 and twice 42 of folded rods are pivoted with two and are the portable bar 43 that the X shape articulates mutually on two, and folded rod 41 ends are connected with trace 44 respectively on two, as shown in Figure 4, two traces 44 respectively interlocks in two end folded rods 22 of relative direction, and should before framework 10 be pivoted with a pull bar 50 that is ㄇ shape in two ends.

As Fig. 2, Fig. 3, two conjunctions 60 that are provided with in addition shown in Figure 5, the two ends of two conjunctions 60 are hubbed at 30 of the two ends of this pull bar 50 and corresponding two after poppets respectively, and be respectively equipped with a location division 51 that is resisted against this after poppet 30 in 50 liang of ends of this pull bar, and these pull bar 50 central authorities are pivoted with a control setup 52, can be for these pull bar 50 both sides along these control setup 52 rotation foldings, as shown in Figure 7.

As Fig. 2, Fig. 3, shown in Figure 5,50 liang of side bottoms of this pull bar correspond respectively to two conjunctions 60 and are provided with an engaging group 70, each engaging group 70 is respectively equipped with a sliding sleeve 71 that stretched by these control setup 52 controls, the both sides of two sliding sleeves 71 are respectively equipped with a protuberance 72, and two conjunctions 60 are provided with one for the chimeric breach 73 of each cooresponding protuberance 72 respectively at both sides, by above-mentioned structure, to finish the quick folding mechanism of the utility model baby stroller, as Fig. 6, shown in Figure 7.

When folding, extremely shown in Figure 5 as Fig. 3, push this control setup 52 by one hand, raise on this pull bar 50 to control 71 slips of two sliding sleeves, make this protuberance 72 break away from each breach 73 partly, again this pull bar 50 is tilted towards these preceding framework 10 directions, make two location divisions 51 break away from two after poppets 30 respectively, and this linkage rod group 40 can be respectively with each articulated section folding closing, these linkage rod group 40 interlocks two traces 44 make the 22 mutual folding closings of two end folded rods, and are somebody's turn to do two top folded rod folding closings of preceding framework 10, these pull bar 50 both sides are that the center bending folds with these control setup 52 both sides respectively simultaneously, can be convenient and reach, fast speed folds baby stroller, with the collapse state of formation as Figure 6 and Figure 7, and after folding, because two location divisions 51 of this pull bar 50 down, to cooperate two back wheels 31, can form at 4 and contact, and the actv. support effect is provided with ground, can stand on ground for the baby stroller after the folding, as shown in Figure 7.
