[0030] As Figures 1 to 9 shown, the present utility model provides a gear adjustment structure for the calf support of a baby stroller, which includes a fixed sleeve 1 and a support rod 2. Both ends of the support rod 2 are slidably arranged within the fixed sleeve 1. Specifically, gear adjustment units are fixedly arranged inside both ends of the support rod 2, and a limiting unit cooperating with the gear adjustment unit is arranged within the fixed sleeve 1. A button unit is movably arranged near the middle of the support rod 2, and the button unit and the gear adjustment unit are connected by a pulling unit. By pressing the button unit, the pulling unit pulls the gear adjustment unit to slide and unlock within the limiting unit, and by pushing and pulling the support rod 2, it slides and locks within the fixed sleeve 1.

[0031] The gear adjustment unit includes a fixing member 3, and the fixing member 3 is fixedly connected to the inside of both ends of the support rod 2 through a first pin shaft 4 passing through the fixing member 3. Both ends of the first pin shaft 4 are inserted and fixed on the outer wall of the support rod 2. Specifically, an unlocking member 5 that slides horizontally along the fixing member 3 is movably arranged on the fixing member 3, and a locking member 6 that slides vertically relative to the unlocking member 5 is also movably arranged on the fixing member 3. The unlocking member 5 and the locking member 6 are arranged perpendicular to each other.

[0032] A horizontal slideway 7 for enabling the unlocking member 5 to slide is arranged on the fixing member 3, and a vertical slideway 8 for enabling the locking member 6 to slide is also arranged on the fixing member 3.

[0033] First inclined surfaces 9 and second inclined surfaces 10 that come into contact and cooperate with each other during the sliding process are respectively arranged on the unlocking member 5 and the locking member 6.

[0034] One end of the locking member 6 near the bottom is a locking end 11, and through holes 12 for enabling the locking end 11 to pass through are aligned and arranged on the fixing member 3 and the support rod 2.

[0035] The limiting unit includes a limiting piece 13. The limiting piece 13 is fixedly connected to the inside of the fixed sleeve 1 through a second pin shaft 14 inserted through the limiting piece 13. The second pin shaft 14 is arranged on the side of the fixed part 3, and both ends of the second pin shaft 14 are inserted and fixed on the outer wall of the fixed sleeve 1. Specifically, a sliding long groove 15 for cooperating with the first pin shaft 4 is provided on the limiting piece 13, and the first pin shaft 4 slides in the sliding long groove 15.

[0036] At least two first gear holes 16 and second gear holes 17 for cooperating with and locking the locking end 11 are provided at the bottom of the fixed sleeve 1.

[0037] The button unit includes a fixed seat 18 fixedly arranged in the support rod 2 and a pinch handle 19 slidably arranged in the fixed seat 18. Specifically, at least one protrusion 20 for cooperating with the pulling unit is provided on the pinch handle 19 extending towards the fixed seat 18.

[0038] The pulling unit includes a steel wire. One end of the steel wire is fixedly arranged in the fixed seat 18, and the other end of the steel wire is fixedly arranged on the gear shifting unit. Specifically, the other end of the steel wire is fixedly arranged on the unlocking piece 5, the top surface of the protrusion 20 is the A surface 21, and the steel wire is in contact connection with the A surface 21.

[0039] The working principle of the present utility model is as follows: Press the pinch handle 19 towards the fixed seat 18 to make the pinch handle 19 slide upwards in the fixed seat 18. Since the steel wire is always in contact connection with the A surface 21 of the protrusion 20 on the pinch handle 19, during the upward sliding of the pinch handle 19, the steel wire is deformed and bent. The steel wire drives the unlocking piece 5 connected to the other end thereof to slide towards the button unit. The unlocking piece 5 slides in the horizontal slideway 7. The first inclined surface 9 on the unlocking piece 5 is in contact connection with the second inclined surface 10 on the locking piece 6. The horizontal sliding of the first inclined surface 9 drives the locking piece 6 to slide upwards along the vertical slideway 8. The locking end 11 of the locking piece 6 leaves the through hole 12 and the first gear hole 16. At this time, it is in the unlocked state. While pressing the pinch handle 19, the user pushes or pulls the support rod 2 inwards or outwards, so that the first pin shaft 4 on the fixed part 3 fixed inside both ends of the support rod 2 slides in the sliding long groove 15 on the limiting piece 13. After adjusting the length of the calf support to the length desired by the user, release the pinch handle 19. The steel wire returns to its original state, the unlocking piece 5 slides back to its original position, the locking piece 6 slides downwards along the vertical slideway 8, and the locking end 11 slides into the second gear hole 17 through the through hole 12 to lock, realizing the gear adjustment of the calf support.

[0040] The advantages of the present utility model are as follows: Through the cooperation of the button unit and the gear shifting unit, the unlocking sliding and gear locking positioning of the support rod 2 in the fixed sleeve 1 are realized, thereby realizing the length adjustment of the calf support. The operation is convenient, the structure is simple, it is suitable for the calf support of infants and young children of different ages, brings comfort to the infants and young children, and improves the use experience.
