DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; in the description of this utility model, "a plurality of" or "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] Please see Figure 1 and Figure 2 As shown, this utility model is a novel baby stroller leg support mechanism, including a leg support plate 1 and a foot pedal 3. The leg support plate 1 is rotatably connected to the front end of the seat 2 through a joint assembly, and the foot pedal 3 is rotatably connected to the front end of the leg support plate 1.

[0037] In the use of the leg rest mechanism of this application, the front end of the leg rest plate 1 is rotatably connected to the front end of the seat 2, and the front end of the leg rest plate 1 is rotatably connected to the foot pedal 3, so that the foot pedal 3 can be folded and unfolded or rotated and unfolded. It is easy to operate. When the stroller is not in use or when the frame is folded and stored, the rotatably mounted foot pedal 3 can be folded and unfolded to avoid collision damage and to avoid affecting the folding effect of the stroller. The rotatably mounted foot pedal 3 can be adjusted to support the baby's legs, thereby improving the baby's riding comfort.

[0038] In this specific implementation, such as Figure 3 and Figure 4 As shown, the front end of the leg rest 1 is provided with an integral support rod 11, which is rotatably connected to the foot pedal 3. The bottom of the foot pedal 3 is provided with an integral elastic sleeve 30, and the elastic sleeve 30 has a notch 300 in the length direction. The support rod 11 is rotatably connected to the elastic sleeve 30 through the notch 300. In the process of rotating and installing the foot pedal 3 in this application, it is convenient to use the elastic sleeve 30 to snap onto the support rod 11, and the foot pedal 3 can be folded and folded or rotated to open along the support rod 11, which is convenient to operate.

[0039] During the folding and collapsing process of the foot pedal 3, a storage groove 10 for rotating and collapsing the foot pedal 3 is provided on the top surface of the leg rest 1; there is a finger operation gap between the groove wall of the storage groove 10 and the contour side of the foot pedal 3; by designing the storage groove 10 on the leg rest 1, the foot pedal 3 can be completely fitted and housed in the storage groove 10, and when in use, the foot pedal 3 can be pulled out by hand.

[0040] In this specific implementation, such as Figure 4 As shown, the foot pedal 3 has several slots 31 evenly distributed at intervals. The slots 31 on the foot pedal 3 are used to remove soil clods from the bottom of the feet, making it easier to clean the foot pedal 3.

[0041] In this specific implementation, such as Figures 5 to 10 As shown, the joint assembly includes a pivot joint sleeve 12, an adjusting sleeve 20, and an unlocking cover 4. The inner circumferential sidewall of the pivot joint sleeve 12 is provided with multiple integrally structured teeth 14. The inner cavity of the adjusting sleeve 20 is slidably connected to the telescopic block 21 through a return spring. The center position of the outer end face of the telescopic block 21 is provided with a protrusion 22, and multiple integrally structured teeth 23 are evenly distributed along the outer circumferential direction of the protrusion 22. The teeth 14 and the teeth 23 are engaged and snapped together. The pivot joint sleeve 12 is integrally structured at the joint position of the leg rest 1, the adjusting sleeve 20 is integrally structured at the joint position of the seat 2, and the unlocking cover 4 is slidably connected to the pivot joint sleeve 12, with its bottom end pressing against the protrusion 22.

[0042] During the design process of the leg rest 1 being rotatably connected to the front end of the seat 2 via a joint assembly, when adjusting the support angle of the leg rest 1, the operator presses the unlocking cover 4, causing the unlocking cover 4 to press inward along the pivot joint sleeve 12 to squeeze the protrusion 22 of the telescopic block 21, causing the telescopic block 21 to contract along the inner cavity of the adjusting sleeve 20 and compress the return spring. At this time, the first tooth 14 and the second tooth 23 disengage and lock, so as to rotate the pivot joint sleeve 12 to adjust the support angle of the leg rest 1. After the adjustment is completed, the unlocking cover 4 is released, and the telescopic block 21 moves outward under the action of the return spring and squeezes the unlocking cover 4 to reset, making it easy to use for the next adjustment. At this time, the first tooth 14 and the second tooth 23 engage and lock, so that the pivot joint sleeve 12 is locked and fixed, and will not rotate.

[0043] In this specific embodiment, arc-shaped guide grooves 24 are symmetrically provided on both sides of the protruding column 22. The arc-shaped guide grooves 24 are slidably guided and connected to the anti-detachment insert plate 15. The anti-detachment insert plate 15 is integrally set on the pivot joint sleeve 12. During the process of rotating the pivot joint sleeve 12 to adjust the support angle of the leg rest plate 1, the anti-detachment insert plate 15 is always guided to rotate along the arc-shaped guide groove 24, which can ensure the safety of the rotation of the leg rest plate 1.

[0044] In this specific embodiment, the unlocking cover 4 is provided with a plurality of insertion feet 40. The insertion feet 40 are used to insert into the guide holes 13 on the connecting hub joint sleeve 12 and press against the protrusion 22. The tail end of the insertion feet 40 is provided with a bent anti-dislodgement ear 41. In the design of the unlocking cover 4 in this application, it is easy to slide and guide the insertion feet 40 to the hub joint sleeve 12 without falling off, so as to facilitate the use of unlocking or locking operations.
