The utility model discloses a but one-hand safety and convenient angle regulation baby rocking chair's theory of operation as follows:

when the elevation angle of the seat support frame 2 needs to be increased or the infant rocking chair is gradually unfolded from a folded state, the clamping and locking operating mechanism 31 and the secondary locking and unlocking mechanism 32 do not need to be unlocked again, and only external force is needed to push the seat support frame 2 to slide upwards relative to the bottom rocking frame 1, at the moment, if the clamping and locking pin 43 is in the second clamping and positioning area 6b, the clamping and locking pin 43 slides towards the first clamping and positioning area 6a along with the angle adjusting slide seat 41, and the elevation angle of the seat support frame 2 is gradually raised; when the latch pin 43 enters the first clamping and positioning area 6a from the second clamping and positioning area 6b, the latch pin 43 is pushed by the jacking elastic member 44, the latch is positioned in one positioning slot 61, the angle adjusting support rod 5 rotates along the hinged position with the seat support frame 2, a fixed angle is formed between the bottom cradle 1 and the seat support frame 2, then an external force is needed to push the seat support frame 2 to slide upwards relative to the bottom cradle 1, at the moment, the latch pin 43 slides out of the positioning slot 412 under the action of an external force, the latch pin 43 is pushed by the jacking elastic member 44, the latch is positioned in the other positioning slot 61, the angle adjusting support rod 5 rotates along the hinged position with the seat support frame 2, another fixed angle is formed between the bottom cradle 1 and the seat support frame 2, and through such simple and convenient operation, in the first positioning area 6a, the angle adjustment of the elevation angle of the seat support frame 2 is realized, can be used safely.

When the elevation angle of the seat support frame 2 needs to be adjusted to be small or gradually folded, by operating the locking operation mechanism 31, when the blocking portion 3141 slides freely and synchronously between one end of the secondary lock unlocking mechanism 32 and the unlocking clamping switch 323 along with the traction pull wire 314, the locking pin 43 unlocks and lifts under the traction action of the traction pull wire 314, slides along with the angle adjusting slide seat 41 in the first locking and positioning area 6a on the angle adjusting slide rail 6, then the locking pin 43 is pushed by the jacking elastic element 44, the locking is positioned in the corresponding positioning clamping groove 61, the angle adjusting support rod 5 and the bottom rocking frame 1 are locked and fixed, so that the angle between the bottom rocking frame 1 and the seat support frame 2 is adjusted, the angle adjustment of the included angle between the bottom rocking frame and the seat support frame 12 is realized, and the comfort level of a baby for taking is met; when the blocking part 3141 is in contact with the unlocking clamping switch 323, the unlocking clamping switch 323 locks and fixes the locking operating mechanism 31, and the traction pull wire 314 and the blocking part 3141 are prevented from continuously sliding synchronously in the secondary locking and unlocking mechanism 32; at this time, the pulling wire 314 cannot pull the unlocking lift latch pin 43 to a height exceeding the height of the stopper portion 62, thereby obstructing the card-locking mechanism 4 from entering the second card positioning region 6b from the first card positioning region 6 a; when the unlocking lock switch 323 is unlocked, the latch operating mechanism 31 is continuously operated, the pulling wire 314 and the blocking portion 3141 can continuously slide in the secondary lock unlocking mechanism 32, the height of the latch pin 43 pulled, unlocked and lifted by the pulling wire 314 exceeds the height of the limiting blocking portion 62 to reach the latch locking mechanism 4 from the first latch positioning region 6a into the second latch positioning region 6b, the baby rocking chair can be gradually folded, and when the latch locking mechanism 4 slides to the final end of the second latch positioning region 6b, the baby rocking chair is in the fully folded state.

The safe unlocking operation mechanism on the baby rocking chair of the utility model avoids the over-complicated operation caused by arranging the two-lock unlocking mechanism 32 and the latch operation mechanism 31 at the same position by arranging the two-lock unlocking mechanism 32 at one side of the latch operation mechanism 31, and prevents the phenomenon of misoperation, thereby achieving the effect of simple operation; meanwhile, the secondary lock unlocking mechanism 32 interacts with the blocking part 3141 to achieve the effect of locking and fixing the locking operating mechanism 31, the use of the locking operating mechanism 31 is limited, the traction pull wire 314 and the blocking part 3141 are prevented from continuously sliding synchronously in the secondary lock unlocking mechanism 32, so that the locking operating mechanism 31 can be operated safely, and the effect of safety protection on the baby taking the baby rocking chair is facilitated.

While the embodiments of the present application have been described in detail, the present application is not limited to the embodiments described above. Even if various changes are made in the present application, the protection scope of the present application is still included.
