[0016] The effect achieved by the above components is as follows: by setting wheels at the bottom of both the front and rear support brackets, the trolley can be moved easily when it is open, and its overall storage volume is not affected when it is folded.

[0017] Preferably, the joint sleeve is fitted with a joint shell.

[0018] The effect achieved by the above components is to protect the internal linkage structure from dust and impact by covering the joint sleeve with a joint shell, thereby improving structural safety and durability.

[0019] Compared with existing technologies, the advantages of this utility model are as follows: By setting up a stroller body and a rotating folding mechanism, the rotating folding mechanism includes a joint sleeve, a front joint, and a push rod joint. Switching between the first and second positions is achieved by sliding the linkage rod within the linkage groove. Only the rotation of the push rod bracket is needed to synchronously drive all components, making operation simple and efficient. The first and second track grooves are adapted to the movement trajectory of the linkage rod, reducing resistance and ensuring a smooth and stable folding process. The seat connector on the joint sleeve can connect to a child seat, expanding its functionality. The wheels at the bottom of the front and rear supports ensure convenient movement, while the joint shell protects the internal structure and improves durability. The overall structure balances ease of operation, multi-functionality, and structural stability, significantly improving the product's practicality and user experience. Attached Figure Description

The linkage groove 9 has a first position (e.g., Figure 2 (as shown) and the second position (as shown) Figure 3 As shown in the figure, the trolley can be folded and unfolded synchronously through the linkage 10, which improves the convenience and synchronization of the folding operation.

[0029] The linkage groove 9 has a first track groove 11 along the inner edge of the push rod joint 8 and a second track groove 12 along the inner edge of the front joint 7. One end of the linkage rod 10 passes through the first track groove 11 and is connected to the push rod joint 8, and the other end of the linkage rod 10 passes through the second track groove 12 and is connected to the front joint 7.

[0030] By setting the first track groove 11 and the second track groove 12 inside the linkage groove 9, one end of the linkage rod 10 passes through the first track groove 11 and connects to the push rod joint 8, and the other end passes through the second track groove 12 and connects to the front joint 7, providing a sliding guide for the linkage rod 10, ensuring the stability of the component's movement trajectory during folding and opening, and avoiding jamming.

[0031] The folding and unfolding of the trolley body 1 is achieved by driving the push rod bracket 5 to rotate relative to the rear bracket 4. The sliding of the linkage rod 10 in the linkage groove 9 synchronously drives the front joint 7 and the push rod joint 8 to rotate relative to the joint sleeve 6.

[0032] The folding and unfolding of the trolley body 1 is achieved by driving the push rod bracket 5 to rotate relative to the rear bracket 4. The linkage rod 10 slides in the linkage groove 9 and synchronously drives the front joint 7 and the push rod joint 8 to rotate relative to the joint sleeve 6, so as to achieve faster overall folding and unfolding, simplify the operation steps, and facilitate single-person operation.

[0033] The first track groove 11 and the second track groove 12 are arranged in a crescent shape.

[0034] By setting the first track groove 11 and the second track groove 12 to be crescent-shaped, the rotation trajectory of the linkage rod 10 is adapted to reduce sliding resistance, making the folding and opening process smoother, while enhancing the uniformity of structural stress and extending service life.

[0035] The joint sleeve 6 is provided with a seat connector 13 for connecting a child seat on the opposite side of the linkage groove 9.

[0036] By arranging a seat connector 13 on the opposite side of the linkage groove 9 along the joint sleeve 6, the stroller's functionality is expanded, and the product's versatility and practicality are improved.

[0037] Both the front support 3 and the rear support 4 are equipped with wheels 14 at their bottom ends.

[0038] By installing wheels 14 at the bottom of both the front support 3 and the rear support 4, the trolley can be moved easily when it is open, and its overall storage volume is not affected when it is folded.

[0039] The joint sleeve 6 is fitted with a joint shell 15.

[0040] By fitting a joint shell 15 onto the joint sleeve 6, the internal linkage structure is protected from dust and impact, thereby improving structural safety and durability.

[0041] In this embodiment 2, like Figures 1 to 4 As shown, in this utility model, by setting up a trolley body 1 and a rotating folding mechanism 2, the rotating folding mechanism 2 includes a joint sleeve 6, a front joint 7, and a push rod joint 8. The first position is achieved by sliding the linkage rod 10 in the linkage groove 9 (e.g., Figure 2 (as shown) and the second position (as shown) Figure 3 The switching mechanism (as shown) only requires rotating the push rod bracket 5 to synchronously drive all components, making operation simple and efficient. The first track groove 11 and the second track groove 12 are adapted to the movement trajectory of the linkage rod 10, reducing resistance and making the folding process smooth and stable. The seat connector 13 on the joint sleeve 6 can be connected to a child seat, expanding its functionality. The wheels 14 at the bottom of the front bracket 3 and the rear bracket 4 ensure convenient movement, while the joint shell 15 protects the internal structure and improves durability. The overall structure takes into account the convenience of operation, the versatility of use, and the stability of the structure, greatly improving the practicality of the product and the user experience.

[0042] In this embodiment 3, like Figures 1 to 4 As shown, in this invention, the rotation of the push rod bracket 5 serves as the driving source, causing the linkage rod 10 to slide within the first track groove 11 and the second track groove 12, thus switching between the first and second positions. The curved trajectory of the track grooves guides the front joint 7 and the push rod joint 8 to rotate synchronously. When the push rod bracket 5 rotates, the linkage rod 10 synchronously drives the front carriage bracket 3 to rotate, causing both to gradually fold together along the rear carriage bracket 4. Simultaneously, the limiting structure on the joint sleeve 6 ensures that the components do not shift during folding, ultimately achieving a smooth transition of the trolley from an open state (all brackets extended, wheels 14 on the ground for support) to a folded state (brackets folded, volume reduced). Through precise coordination of the mechanical structure, a labor-saving and stable folding operation is achieved, balancing support strength during use with portability during storage.
