[0054] Embodiment

[0055] The purpose of this embodiment is to facilitate the solution of the problem in the prior art that usually the user steps on the body pedal with the foot and pulls up the vertical rod by hand to disengage the vertical rod from the clutch sleeve, and the vertical rod can be rotated and folded. However, when the vertical rod of the baby carriage is unfolded and used in this folding method, there will still be a phenomenon of loose connection at the joint, and it cannot be completely fixed, especially it is more obvious after long-term use. Moreover, it is not convenient for the user to exert force to lift the vertical rod for folding or press it down for unfolding and use.

[0056] For this reason, a folding device for the vertical rod of a baby carriage is provided in this embodiment. The limiting member and the folding connecting member in the folding device for the vertical rod of the baby carriage adopt a snap connection. In the use state, the rotation of the folding connecting member in the folding notch can be completely limited, effectively avoiding the loosening phenomenon. When folding is required, by releasing the snap state between the limiting member and the folding connecting member, the folding connecting member can be rotated and folded onto the body bracket. The user can drive the limiting member outside the body bracket to disengage the clamping state of the folding connecting member. The way to release the limit is simple and labor-saving. Compared with the pull-up type folding vertical rod in the prior art, the snap connection method is more reliable and reduces the safety risk during use.

[0057] Refer to Figure 1-3 As shown in FIGS. 9 and 10, a folding device for the vertical rod of a baby carriage includes: a body bracket 1, and the body bracket 1 is provided with a folding notch 11; and

[0058] a vertical rod assembly 2, the vertical rod assembly 2 includes a folding connecting member 21 adapted to the folding notch 11, and the folding connecting member 21 is placed in the folding notch 11 and can rotate in the folding notch 11;

[0059] a limiting rotation assembly 3, the limiting rotation assembly 3 is arranged on the body bracket 1, and the limiting rotation assembly 3 includes a limiting member 31, and the limiting member 31 is used for snap connection with the folding connecting member 21 to limit the rotation of the folding connecting member 21 in the folding notch 11;

[0060] The limiting member 31 is also used for separating from the folding connecting member 21 to allow the folding connecting member 21 to rotate in the folding notch 11.

[0061] Refer to Figure 1-3As shown, specifically, in this embodiment, the limiting and rotating assembly 3 further includes a fastener releasing member 32. The fastener releasing member 32 is movably connected to the limiting member 31. When the fastener releasing member 32 is pushed, it drives the limiting member 31 to separate from the folding connecting member 21 to release the limitation on the folding connecting member, allowing the folding connecting member 21 to rotate in the folding notch 11.

[0062] Referring to Figure 1-3 As shown, specifically, in this embodiment, the limiting member 31 is arranged on one side of the folding connecting member 21. At least one snap groove 211 is provided on at least one side of the folding connecting member 21. The limiting member 31 is slidably connected to the vehicle body bracket 1. The limiting member 31 includes a snap protrusion 311 adapted to the snap groove 211. A return spring 33 is arranged between the inner wall of the vehicle body bracket 1 and the limiting member 31. In the initial state, the elastic force of the return spring 33 always snaps the snap protrusion 311 into the snap groove 211. The fastener releasing member 32 includes a ramp portion 321, and the limiting member 31 includes a guiding portion 312 adapted to the ramp portion 321. When the fastener releasing member 32 is pushed, the ramp portion 321 and the guiding portion 312 slide relative to each other, so that the snap protrusion 311 of the fastener releasing member 32 disengages from the snap groove 211 in a direction perpendicular to the fastener releasing member 32. It should be added that the limiting member 31 can be arranged on one side or both sides of the folding connecting member 21 to increase the connection stability. In this embodiment, snap grooves 211 are respectively arranged on both sides of the folding connecting member 21, and the number of snap grooves 211 provided on each end face is 2. The two snap grooves 211 are on the same circle around the rotation center of the folding connecting member 21, 90 degrees apart. When corresponding to the vertical rod, it is perpendicular to the vehicle body bracket 1 and parallel to the vehicle body bracket 1 after folding. The end face between the snap grooves 211 is flat, which is convenient for the snap protrusion 311 to slide along the flat end face to another snap groove 211 after disengaging from one snap groove 211. The elastic force of the return spring 33 makes the snap protrusion 311 automatically snap into the snap groove 211, and the user does not need to keep pressing the fastener releasing member 32 all the time.

[0063] Referring to Figure 1-3 As shown, specifically, in this embodiment, the folding notch 11 is arranged at the top of the vehicle body bracket 1. A fastener releasing port 12 for the fastener releasing member 32 to extend out of the vehicle body bracket 1 is arranged at the bottom of the vehicle body bracket 1.
