Detailed ways

As shown in the accompanying drawings of the utility model, a child stroller includes a stroller frame 1, a front wheel 2 and a rear wheel 5 respectively arranged below the stroller frame 1, and the The cart frame 1 includes a front wheel bracket 3, a bottom bar 4 whose front end is rotatably connected to the front part of the front wheel bracket 3, and a rear wheel bracket whose upper end is rotatably connected to the middle part of the front wheel bracket 3 9. The push rod 10 rotatably connected to the rear end of the front wheel bracket 3, the push rod 10 extends downward from the rotatable connection with the rear end of the front wheel bracket 3 to form a downward extension of the push rod Section 16, the lower extension section 16 of the push rod is rotatably connected with the upper end of the push rod link 15, the lower end of the push rod link 15 is rotatably connected with the middle part of the rear wheel bracket 9, and the push rod The left and right sides of the vehicle frame 1 are provided with rear wheel brackets 9, and a cross bar 11 is fixedly arranged between the rear wheel brackets 9 on both sides, and the rear end of the bottom bar 4 rotates with the cross bar 11. connect.

As shown in the accompanying drawings, the front part of the bottom bar 4 is rotatably connected with the front wheel link 6, the front wheel 2 is arranged on the bottom of the front wheel link 6, and the front wheel link A locking mechanism for locking the relative position of the front wheel link 6 and the front wheel bracket 3 is arranged between the rod 6 and the front wheel bracket 3 .

As shown in accompanying drawing 4-accompanying drawing 6, described locking mechanism package is arranged on the hook 7 on the described front wheel connecting rod 6, the hook nose 8 that is fixedly arranged on the front portion of front wheel support 3, in locking mechanism In the locked state, the hook 7 is hooked on the hook nose 8 . The hook 7 has a groove 12, and the hook nose 8 is located in the groove 12 when the locking mechanism is in a locked state.

As shown in FIG. 7 , one end of the hook 7 is rotatably arranged on the front wheel link 6 , and a torsion spring 13 is arranged between the front wheel link 6 and the hook 7 .

When the stroller is folded, as the angle between the front wheel bracket 3 and the bottom bar 4 changes, as shown in Figure 5, the front wheel link 6 is displaced relative to the front wheel bracket 3, When the hook 7 breaks away from the hook nose 8, the front wheel link 6 and the front wheel 2 can be folded to the position shown in Figure 6 .

As shown in Figure 6, the outer surface of the hook 7 has a guide slope 14, when the child stroller enters the unfolded state from the folded state, the hook nose 8 enters the groove 12 along the guide slope 14, this The state is shown in Figure 5.
