Detailed ways

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

Referring to the rockable cart shown in Figures 1 to 4, the cart includes a cart frame with an unfolded position and a folded position, a front wheel assembly 3 located at the bottom front of the cart frame, The rear wheel assembly 4 at the bottom rear part is also provided with a locking mechanism (not shown in the figure) for locking the cart frame in the unfolded position on the cart frame. The stroller frame includes an arc-shaped underframe 1 and side supports 2 arranged above the arc-shaped underframe 2 and on both sides thereof.

The arc-shaped underframe 1 includes an arc-shaped bar 11 extending along the front and rear direction of the cart frame on both sides, a cross bar 12 for connecting the arc-shaped bars 11 on both sides, and the arc-shaped bar 11 is arched downwards, and the front wheel Assembly 3 and rear wheel assembly 4 are arranged on the front part and the rear part of arc-shaped underframe 1 in an upturnable manner respectively. The bottom of the arc-shaped underframe 1 is in contact with the ground, and the arc-shaped underframe 1 is suspended in the air. When the rockable trolley is used as a rocking chair, the front wheel assembly 3 and the rear wheel assembly 4 are respectively turned upwards and separated from the ground. The arched part of the arc rod 11 of the arc-shaped underframe 1 is in contact with the ground, so that the cart as a whole can swing along the front-rear direction.

Referring to shown in each accompanying drawing, side support 2 all comprises front support 21, rear support 22, push rod 23, handrail bar 24, and the bottom of front support 21 is connected on the front part of arc-shaped underframe 1 in rotation, and the front part of push rod 23 The bottom is rotatably connected with the front support 21 top, and the bottom of the rear support 22 is rotatably connected with the rear part of the arc-shaped underframe 1 . The front bracket 21 and the rear bracket 22 are intersected and arranged, and the two are slidably and rotatably connected by a sliding sleeve 25, where the front bracket 21 and the rear bracket 22 are connected in the following manner: the sliding sleeve 25 is rotatably set by a pin On the middle part of the rear bracket 22 , a sliding sleeve 25 is slidably sleeved on the front bracket 21 along the length direction of the front bracket 21 . The handle bar 24 is connected between the upper part of the rear bracket 22 and the push rod 23 .

In this way, when the cart is folded, the locking mechanism is unlocked to the unfolded position of the cart frame, the push rod 23 is pushed forward, the push rod 23 is turned forward relative to the front bracket 21, the top of the front bracket 21 is pressed down, and the front bracket 21 rotates relative to the rear bracket 22, and the upper part of the rear bracket 22 goes down under the action of the sliding sleeve 25, as shown in Figure 2, continue to press the push rod 23 downward, and the cart frame can be folded into the folded state shown in Figure 3 .
