【detailed description】

The present invention will be further described below in conjunction with the accompanying drawings:

As shown in FIG. 1 to FIG. 4 and FIG. 8 to FIG. 11 , the stroller frame can be moved from the deployed position to the folded position, including:

Front frame 1, the front frame 1 is connected to the front wheel 1a;

a rear frame 2, the rear frame 2 is connected to the rear wheel 2a;

a frame 5, the frame 5 includes a flat rod 51 and an upper rod 52 extending upward from a rear portion of the flat rod 51, and the front end of the flat rod 51 is rotatably coupled to the upper end of the front frame 1, The upper end of the upper rod 52 is rotatably connected to the middle portion of the push frame 3;

As shown in FIGS. 8 to 10, the push frame 3, the side armrest 4, the front frame 1 and the drawbar 6 group The four-bar linkage structure, and the push frame 3, the frame 5, the linkage rod 7 and the rear frame 2 also constitute a four-bar linkage mechanism, so in the process of the upper end of the push frame 3 rotating forward, the lower end of the push frame 3 is oriented The rear side movement (as shown by the arrows in FIG. 8 and FIG. 9) further causes the respective components of the two four-link structures to be interlocked, so that the front frame 1 and the rear frame 2 are folded and folded, and the volume is small after folding. The utility model has the advantages of compact structure, small occupied space, convenient carrying, convenient folding operation and flexible folding. Moreover, the frame 5 is composed of a flat rod 51 and an upper rod 52 extending upward from the rear of the flat rod 51. Therefore, the flat rod 51 and the upper rod 52 both interlock and fold the stroller skeleton in the four-bar linkage structure. The role of the seat, which serves as a seat support, is very clever.

As shown in FIG. 1 to FIG. 4, the stroller frame further includes a front armrest assembly 8, and the front armrest assembly 8 includes a grab bar 81 hinged at a lower end to the upper rod 52. There is a drag rod 82 hinged between the grab bar 81 and the middle of the drawbar 6 and capable of folding the front armrest assembly 8 when the stroller frame is folded. The upper end of the grab bar 81 is also connected with a U-shaped grip. Rod 83. In the process of folding the stroller frame, the front armrest assembly 8 can also follow the folding, so as to avoid the defect that the stroller can be folded after the front armrest assembly needs to be removed in the traditional stroller structure, so that the stroller folding is more convenient and quick.

As shown in FIG. 2, FIG. 5 and FIG. 7, the flat section rod 51 is connected with a seat plate 9, and the rear frame 2 is provided with a rear crossbar 10 at the upper end thereof, so as to keep the stroller skeleton in an unfolded state. 11 is provided between the rear crossbar 10 and the seat plate 9.

As shown in FIGS. 2, 5, 6, and 7, the locking device 11 includes a left sliding sleeve 111 and a right sliding sleeve 112 which are disposed on the rear crossbar 10 and are slidable on the rear crossbar 10. The left sliding sleeve 111 and the right sliding sleeve 112 are respectively provided with locking hooks 113, and the seat plate 9 is provided with a receiving hole 115 for the locking groove 113 to extend into the latching plate 113 when the stroller frame is unfolded, and between the left sliding sleeve 111 and the right sliding sleeve 112. Spring (not shown). When the stroller skeleton is unfolded, the locking hook 113 hooks the card slot 114 on the seat plate 9, so that the lower end of the push frame 3 cannot move backward, so that the stroller skeleton remains in the unfolded state, and when the stroller skeleton needs to be folded, the left slide is made. The sleeve 111 and the right sliding sleeve 112 move toward each other, and the locking hook 113 no longer hooks the latching position 114, and the locking hook 113 is withdrawn from the retaining hole 115. At this time, the locking device 11 is unlocked, and the stroller skeleton can be folded.
