Description

Technical Field

[0001] This utility model relates to the field of baby product technology, specifically to a sliding folding structure for a baby stroller after unlocking. Background Technology

[0002] With the popularization of the multiple-child policy, more and more families with multiple children are emerging. In families with newborns and toddlers, strollers are an extremely important household item, which can play an effective role in helping to take care of the baby. In order to reduce the space occupied, existing strollers are usually folded after use. However, conventional strollers have independent joints that are used to connect to the front and rear legs separately. When folding, multiple joints will collide, resulting in an unsatisfactory folding effect. Utility Model Content

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

[0004] To solve the aforementioned existing technical problems, this utility model adopts the following solution: a sliding folding structure for a baby stroller, including a push rod, a support rod, a connecting joint, a front wheel, and a rear wheel. The push rod is equipped with an unlocking component. The bottom ends of both ends of the push rod are sleeved onto the support rod. The support rod passes through the connecting joint and is installed on a baffle. The front wheel is installed at the bottom of the baffle. A fixing rod is sleeved on the baffle. The fixing rod is placed at the bottom of the support rod and installed on the connecting joint. The bottom of the connecting joint is provided with a sliding groove, and the sliding groove is connected to the rear wheel through a rear foot rod.

[0005] Preferably, a cover plate is installed on the connecting joint, an unlocking joint is provided on the inner side of the cover plate, an unlocking block is installed on the unlocking joint, a ramp is provided at the bottom of the unlocking block, the unlocking block passes through the unlocking joint and is connected to a ramp on the moving block via ramp one, and ramp two is movably installed in the limiting groove on the surface of the cover plate.

[0006] Preferably, a swing plate is installed between the support rod and the rear foot rod, wherein the swing plate on the support rod is connected to a sliding block built into the support rod through a bearing, and the bottom of the sliding block is mounted on the fixed rod through a connecting shaft.

[0007] Preferably, the sliding block is equipped with an extrusion plate, the bottom slope three of the extrusion plate is connected to the slope four of the push-pull plate, and the push-pull plate is equipped with a connecting shaft.

[0008] Preferably, positioning sleeves are installed on the support rod and the fixing rod.

[0009] Preferably, the support rod drives the baffle to slide along the fixed rod.

[0010] This utility model provides a sliding folding structure for a baby stroller using the above-mentioned technical solution. By optimizing the structural design, it avoids wobbling when folded and increases the folding effect. Compared with the prior art, it has the following advantages:

[0011] 1. By unlocking the push rod and striking the sliding block, the fixed rod is disengaged from the fixed rod, thus unlocking the push rod from the fixed rod.

[0012] 2. The baffle moves by supporting the rod, which in turn drives the rear foot rod to rotate along the direction of the fixed rod, thus achieving the overall folding effect. Attached Figure Description

[0020] like Figures 1 to 6As shown, a sliding folding structure for a baby stroller includes a push rod 1, a support rod 2, a connecting joint 3, a front wheel 4, and a rear wheel 5. An unlocking component 6 is installed on the push rod 1. The bottom ends of the push rod 1 are sleeved onto the support rod 2. The support rod 2 passes through the connecting joint 3 and is installed on a baffle 7. The front wheel 4 is installed at the bottom of the baffle 7. A fixing rod 8 is sleeved on the baffle 7, positioned at the bottom of the support rod 2 and installed on the connecting joint 3. The bottom of the connecting joint 3 has a sliding groove 9, which is connected to the rear wheel 5 via a rear foot rod 10. A cover plate 11 is installed on the connecting joint 3. An unlocking joint 12 is located inside the cover plate 11. An unlocking block 13 is installed on the unlocking joint 12, and a ramp 14 is provided at the bottom of the unlocking block 13. After the unlocking block 13 passes through the unlocking joint 12, it is connected to the second ramp 16 on the moving block 15 via the first ramp 14. The second ramp 16 is movably installed in the limiting groove 17 on the surface of the cover plate 11. A swing plate 18 is installed between the support rod 2 and the rear foot rod 10. The swing plate 18 on the support rod 2 is connected to the sliding block 19 built into the support rod 2 via a bearing. The bottom of the sliding block 19 is installed on the fixed rod 8 via a connecting shaft 20. A pressing plate 21 is installed on the sliding block 19. The third ramp 22 at the bottom of the pressing plate 21 is connected to the fourth ramp 24 on the push-pull plate 23. A connecting shaft 20 is installed on the push-pull plate 23. A positioning sleeve 25 is installed on the support rod 2 and the fixed rod 8. The support rod 2 drives the baffle 7 to slide along the fixed rod 8.

[0021] In actual operation, after using the stroller, press the unlocking block 13. The ramp 14 at the bottom of the unlocking block 13 drives the ramp 2 16 on the moving block 15 to move, causing ramp 2 16 to disengage from the limiting groove 17 on the cover plate 11. At this time, the connecting joint 3 and the unlocking joint 12 are unlocked. Then, the seat, guardrail, and other structures installed on the stroller are removed to facilitate the subsequent folding of the stroller. After removal, press the unlocking piece 6 to unlock the push rod 1. After unlocking, the push rod 1 slides along the inner cavity of the support rod 2 and is then moved by the hand... The bottom of the push rod 1 impacts the squeezing plate 21 on the sliding block 19. After the impact, the ramp 3 22 on the squeezing plate 21 drives the ramp 4 24 on the push-pull plate 23 to move the connecting shaft 20, causing the connecting shaft 20 to disengage from the fixed rod 8. When the push rod 1 is pushed down and abuts against the top end face of the support rod 2, it will push the support rod 2 to move the baffle 7. The swing plate 18, which is mounted on the support rod 2 through the pivot, will drive the rear leg rod 10 to swing accordingly, so that the rear leg rod 10 rotates along the direction of the fixed rod 8 through the sliding groove 9, thus completing the folding effect of the entire baby stroller and making it more convenient to use.
