[0001] This utility model relates to the field of baby product technology, specifically to an unlocking folding structure for a baby stroller that is easy to fold. Background Technology

[0002] With the popularization of the multiple-child policy, more and more families are having multiple children. In families with newborns and toddlers, baby strollers are an extremely important household item, which can play an effective role in helping to take care of the baby. In the original baby stroller market, the structure of the stroller is usually relatively fixed. After use, the baby stroller will be left unused and inconvenient to fold. Most existing baby strollers also use folding methods to fold and store, but these folding methods are relatively complicated to operate. The folded baby stroller still takes up a lot of space and is inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an unlocking and folding structure for a baby stroller that is simple in structure and easy to adjust.

[0004] To solve the above-mentioned existing technical problems, the present invention adopts the following solution: an unlocking and folding structure for a baby stroller, including a push rod, a front leg rod and a rear leg rod, wherein the bottom of both ends of the push rod are fitted with rotating joints, the rotating joints are connected to the front leg rod, a support is installed on the front leg rod, the support is connected to the rear leg rod through a pivot, and a rear wheel is installed at the end of the rear leg rod.

[0005] Preferably, the push rod is provided with a lifting plate, which is inserted and installed on the sliding sleeve. The surface of the sliding sleeve is provided with a mounting groove, and a spring is installed on the mounting groove. The bottom of the spring is installed on the swing plate. The through slot on the surface of the swing plate is connected to the connecting groove on the surface of the lifting plate through a connecting shaft. The bottom of the swing plate is installed on the moving block, and the moving block is placed inside the front foot rod.

[0006] Preferably, a connecting joint is sleeved on the push rod, the connecting joint is connected to the adjusting rod, and the adjusting rod is installed on the rear foot rod through the adjusting sleeve.

[0007] Preferably, the push rod has a connecting hole on its surface, and the connecting hole is connected to the fixing groove on the swing plate by a pin.

[0008] Preferably, the lifting plate drives the swing plate to move the moving block.

[0009] This utility model provides an unlocking and folding structure for a baby stroller, employing the aforementioned technical solution. By optimizing the structural design, it solves the problems of complex operation, poor stability, and inflexible unlocking in existing baby stroller folding structures. Compared with the prior art, it has the following advantages:

[0010] 1. The stroller can be unlocked with a simple pull-out operation, and the subsequent folding process is also easy, without complicated steps, making it convenient for parents to quickly fold and unfold the stroller and improve its efficiency.

[0011] 2. It is equipped with a pin fixing structure, which can effectively fix the swing plate when the stroller is unfolded and used to prevent the stroller from folding accidentally and ensure the safety of the baby during use; at the same time, the connection between the components is firm and the structure is highly stable.

[0016] like Figures 1 to 3 As shown, an unlocking and folding structure for a baby stroller includes a push rod 1, a front leg 2, and a rear leg 3. Rotating joints 4 are sleeved at the bottom of both ends of the push rod 1, and the rotating joints 4 are connected to the front leg 2. A support member 5 is installed on the front leg 2, and the support member 5 is connected to the rear leg 3 via a pivot 6. A rear wheel 7 is installed at the end of the rear leg 3. A lifting piece 8 is provided inside the push rod 1, and the lifting piece 8 is inserted into a sliding sleeve 9. A mounting groove 10 is provided on the surface of the sliding sleeve 9, and a spring 11 is installed in the mounting groove 10. The bottom of the spring 11 is installed on a swing plate 12. The slot 13 on the surface of the moving plate 12 is connected to the connecting groove 15 on the surface of the lifting plate 8 via the connecting shaft 14. The bottom of the swing plate 12 is mounted on the moving block 16, which is placed inside the front foot rod 2. A connecting joint 17 is sleeved on the push rod 1, which is connected to the adjusting rod 18. The adjusting rod 18 is mounted on the rear foot rod 3 via the adjusting sleeve 19. The push rod 1 has a connecting hole 20 on its surface, which is connected to the fixing groove 21 on the swing plate 12 via a pin. The lifting plate 8 drives the swing plate 12 to move the moving block 16.

[0017] In actual use, when the baby stroller needs to be folded after use, the push rod 1 is unlocked by the unlocking device installed on it. Then, the push rod 1 is pushed down, causing the lifting piece 8 to move along the mounting groove 10 on the surface of the sliding sleeve 9. The lifting piece 8 is provided with a connecting groove 15. During the movement of the lifting piece 8, the connecting shaft 14 moves along the connecting groove 15, thereby driving the swing piece 12 to move back and forth. During the movement of the swing piece 12, the moving block 16 is driven to move within the front leg 2, which facilitates the folding of the push rod 1. The rear leg 3 is connected to the support member 5 through the pivot 6. When the push rod 1 is folded, the rear leg 3 can also be folded simultaneously, effectively utilizing space and making it convenient to use.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
