Description

Technical Field

[0001] This utility model relates to the field of rocking chair technology, and in particular to an angle adjustment structure for an infant rocking chair. Background Technology

[0002] When a baby is born, the sudden disappearance of the shaking stimulation signals received in the womb can cause the infant to feel uneasy, leading to a desire to be rocked again. Rocking the baby in a baby rocker can provide this satisfaction, reduce crying, and promote healthy growth. Furthermore, a baby rocker can reduce the burden on parents and free up their hands. When parents are working or busy with housework, they can place the baby in the rocker, which is both safe and allows parents to do other things.

[0003] Once assembled, existing baby rockers have a fixed tilt angle that cannot be adjusted. This makes it impossible to change the sitting or reclining angle of the rocker. In addition, most rockers have unstable rocking structures and violent vibrations, thus they cannot meet different needs and have limitations in use. Summary of the Invention

[0057] Specifically, when adjusting the tilt angle of the seat 9, the user first presses down the unlock button 62 to disengage the unlocking part 63 from the limiting groove 72, thereby unlocking the locked state of the handle 71. Then, by using external force, the handle 71 moves from the fixed tube 4 to the connecting tube 5. This allows the handle 71 to drive the slide plate 75 from the fixed tube 4 to the connecting tube 5 via the connecting rope 72. The pushing part engages with the mating part to disengage the recess 751 from the boss 741, causing the positioning rod 74 to retract at the opening position, thereby disengaging the positioning rod 74 from the positioning hole 41. This allows the connection to be adjusted. The connection between tube 5 and fixed tube 4 is unlocked. Then, by external force, the connecting tube 5 moves from the support frame 2 towards the base 1 or from the base 1 towards the support frame 2 until the positioning rod 74 moves to the next positioning hole 41. Under the elastic force of the first spring 76, the positioning rod 74 returns to its original position so that it passes through the positioning hole 41, thereby establishing a connection between the positioning rod 74 and the positioning hole 41. At the same time, the connecting tube 5 and fixed tube 4 are locked together. In addition, the unlocking key 62 returns to its original position under the elastic force of the third spring 64 so that the unlocking part 63 establishes a connection with the limiting groove 72, thereby locking the handle 71 in a locked state.

[0058] In this embodiment, since the base 1 is tilted upwards from back to front and the support frame 2 is tilted upwards from front to back, the lower end of the base 1 and the lower end of the support frame 2 are both in contact with the ground. Anti-slip pads 14 are respectively provided on the lower end of the base 4 and the left and right sides of the lower end of the support frame 5. Multiple connecting segments are arranged sequentially along the front-back direction on the anti-slip pads 14, and the connection between two adjacent connecting segments is an arc transition. This ensures that the lower end of the base 1 and the lower end of the support frame 2 can fit well with the ground regardless of the tilt angle of the support frame 2, thereby effectively improving the anti-slip performance of the anti-slip pads 14.

[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
