Two connecting handles 33 (as shown in FIG. 4 ), the two connecting handles 33 are pivotally connected to a pair of connecting rods 34 (as shown in FIG. 2 ), and the other end of the connecting rod 34 of the rear wheel strut 30 is pivotally connected to the main rod 40 bottom position. the

A main rod 40, the bottom is supported by the middle of the rear wheel strut 30 (the position of the shackle 32) and the connecting rod 34, the front end of the main rod 40 is supported by the front wheel strut 20, and the rear end of the main rod 40 is a cylinder 41 , there is a buckle device 50 in the barrel for the positioning of the shackle 32 of the rear wheel strut 30, and a swing plate 82 is respectively connected to both sides of the buckle device 50, the bottom end of the swing plate 82 is pivotally connected with the horizontal rod 24, and the main rod 40 is provided with a slide rail 42, and a slide rail 421 is arranged below, which is used for introducing into the space 22 of the front wheel strut 20, and the inner sleeve 221 fits with the slide rail 42 and the slide rail 421 to be in a tight fit state, so as to facilitate the expansion and contraction. Wheel strut 20 and positioning, make main pole 40 and front wheel strut 20 phase positioning, main pole 40 front end is positioned with a column pin 401 a front head 402, and the stop portion 222 of front wheel strut 20 is for front head 402 to abut against, After the main rod 40 enters the accommodation space 22 of the front wheel strut 20, it will only slide and cannot be disengaged. the

As shown in Figures 4-6, the buckle device 50 distributed on both sides (or one side) of the cylinder body 41 includes: a cylinder 51, a buckle plate 52, a guide rod 53 and a combined cap 54, inside the cylinder 51 A spring bar 55 is pivotally positioned so that the buckle plate 52 is squeezed by the spring bar 55, the buckle plate 52 can be restored to its original shape by the spring bar 55, the buckle plate 52 hooks the shackle 32 of the rear wheel strut 30, and the guide rod 53 is positioned In the combination cap 54, the guide rod 53 is pushed against by a spring 56 and pulled by a rope 57, and the rope 57 is pulled by a pull handle 811 (as shown in Figure 1), and the pull handle 811 is assembled on the push rod 81, and the guide rod 53 There is a guide inclined surface 531 on it. When the guide rod 53 moves back, the guide inclined surface 531 pushes the pinch plate 52, causing the pinch plate 52 to release and unhook the shackle 32 of the rear wheel strut 30. There is a pivot joint at the end of the push rod 81 812, the combined cap 54 combines the swinging plate 82 with the pivot joint 812 of the push rod 81, and the end of the push rod 81, the swinging plate 82, the combined cap 54 and the cylinder 51 are combined with the number combined column 58, generally a cylinder Both sides of 41 are respectively provided with symmetrical structural components, but the buckle plate 52, guide rod 53, elastic bar 55 and rope 57 can be set on both sides, and also can only be set on one side. the

A seat socket 60, each side of the front end of the seat socket 60 is provided with a pivot hole 61, the pivot hole 61 is used for the pivot connection of the vertical rod 23, and the rear end is respectively provided with a pivot hole 62, and the pivot hole 62 is provided for the pivot connection. The barrel 41 of the main rod 40 and the pivot joint 812 of the push rod 81 are pivotally connected, the armrest 80 and the two push rods 81 are combined, and the pivot joint 812 at the end of the push rod 81 is pivotally connected to the two outer sides of the barrel 41 of the main rod 40 , there is a moving part 813 (i.e. the bottom end of the push rod 81) in the pivot joint 812, the moving part 813 is an oval tube, and there is an oval hole 821 opposite to the swing plate 82, the moving part 813 enters the oval hole 821, so that the push rod 81 The end and the swing plate 82 rotate an angle synchronously, and there are two symmetrical turning mechanisms 801 between the armrest 80 and the two push rods 81, so that the armrest 80 can be folded from the two push rods 81, and the two sides of the seat socket 60 are for A seat 70 is inserted for positioning. the

Combining the above structures, the utility model is a folding structure of a baby carriage, as shown in Fig. The moving rope 57 pulls the guide rod 53, and the guide inclined surface 531 of the guide rod 53 pushes the buckle 52, so that the buckle 52 no longer hooks the shackle 32 of the rear wheel strut 30, and the rear wheel strut 30 must be released. The shackle 32 of the rear wheel strut 30 can be displaced forward, but the connecting rod 34 is still supported by the main rod 40 (as shown in Figure 9), and then the armrest 80 and the push rod 81 are displaced forward. At this time The upper pivot joint 812 of the push rod 81 is linked with the swing plate 82 to rotate at an angle synchronously, and the swing plate 82 deflects backward, as shown in Fig. 2, 9 and 10, to pull the horizontal bar 24 to move backward; Armrest 80 and push rod 81 move forward, and push seat socket 60 to move forward, and vertical bar 23 is oblique shape, and this seat socket 60, vertical bar 23, horizontal bar 24 and swinging plate 82 are approximately obliquely flat quadrilateral support, and continue to push forward the armrest 80 and push rod 81, to approximately fit the front wheel strut 20, as the lever principle, with the cylinder 41 as the point of support, the armrest 80 and push rod 81 are long levers, Therefore, the seat socket 60, the vertical bar 23, the horizontal bar 24 and the swing plate 82 can be closed and closed in a labor-saving manner, and the horizontal bar 24 is driven to move the front wheel strut 20 backwards, so that the front wheel strut 20 moves toward the front wheel strut. Retract, the front wheel strut 20 retracts on the main rod 40, and then the armrest 80 is folded up from the push rod 81 to complete the folding, so that the volume is greatly reduced. the

Since the front wheel strut 20 shrinks backward from the main rod 40, the front and rear width and volume are reduced, and both the height and the front and rear width are greatly reduced compared with conventional strollers, reaching the minimum folded volume. the
