[0001] The utility model relates to the technical field of baby cradles, in particular to a rotating structure of a two-point baby cradle. Background Art

[0002] In the aviation service industry, airline baby cradles can be provided for younger babies. The cradle mainly includes a top frame, a cradle cloth and a bottom support frame. The baby sleeps in the inner cavity formed by the cradle cloth, so that the baby can get proper rest during the flight. It is also convenient for parents to take care of the baby during the flight, such as feeding, changing diapers, etc.

[0003] An existing Chinese public patent (authorization announcement number: CN210455227U) mentions an onboard baby cradle, which can be based on the stability principle of the triangular structure. The bed frame is fixed to the wall or board of the aircraft or other mid-air position by three fixing pins distributed in a triangular position, which can ensure that the baby cradle is firmly fixed in the air to avoid the baby cradle from being shaken during the journey and causing discomfort.

[0004] When traveling with a baby on an airplane, you can ask the flight attendant to provide a cradle for the baby to reduce the burden on parents to take care of the baby during the flight. However, since the existing cradle protection height is mostly fixed, when the baby is not sleeping but playing in the cradle, he or she may try to climb out of the cradle or turn over, which may pose certain safety hazards and increase the risk of falling.

[0038] When using the cradle, first align the two quick-connect components with the small holes set in the aircraft cabin, and then connect them to the aircraft cabin so that the top rod 4 is fixed on one side of the cabin, and then the staff rotates the rotating rod 2, and the rotating rod 2 rotates to drive the connecting block 3 to rotate inside the rotating block 1. The cradle cloth is pre-laid inside the cradle. After use, by taking out the rotating shaft 8, the rotating shaft 8 will squeeze the steel ball 7 when taking it out. The steel ball 7 and the engaging groove 27 are both set to an arc shape. When the rotating drawer is pulled out, the spring 6 can be compressed under the sliding action of the arc surface, so that the steel ball 7 is downwardly disengaged from the engaging groove 27. At this time, the limit on the rotating block 1 is released, so that the rotating rod 2 is rotated to the bottom of the top rod 4 for folding and storage, which is convenient for next use. The protective height of the cradle can be increased by the protective mechanism, and the risk of the baby falling can be reduced. The stability of the cradle can be further increased by the reinforcement mechanism.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The protection mechanism includes a mounting block 9 fixedly connected to both sides of the push rod 4, a protective cover 10 is slidably connected inside the mounting block 9, two slide grooves are equidistantly provided on both sides of the inner wall of the mounting block 9, two sliders 11 are equidistantly fixedly connected on both sides of the protective cover 10, the sliders 11 are slidably connected to the slide grooves, observation windows 12 are equidistantly provided on both sides of the protective cover 10, a push-pull handle 13 is fixedly connected to the side of the protective cover 10 away from the push rod 4, and a fixing piece is provided on the side of the mounting block 9 away from the push rod 4.

[0040] Among them, the fixing part includes a fixing block 14 fixedly connected to the side of the mounting block 9 away from the top rod 4, the fixing block 14 is set to be L-shaped, the internal thread of the fixing block 14 is connected to a threaded rod 15, one end of the threaded rod 15 is fixedly connected to a handle, the end of the threaded rod 15 away from the handle passes through the fixing block 14 and is rotatably connected to a clamping block 16, and the clamping block 16 conflicts with the protective cover 10 when moving.

[0041] In addition, a metal plate 17 is fixedly connected to a surface of the clamping block 16 close to the protective cover 10 , and a surface of the metal plate 17 away from the clamping block 16 is set to be a rough surface.

[0042] In addition, a guide rod 18 is fixedly connected to a surface of the clamping block 16 away from the metal plate 17 , and an end of the guide rod 18 away from the clamping block 16 penetrates the fixing block 14 , and the guide rod 18 is slidably connected to the fixing block 14 .

[0043] When adjusting the protective height of the cradle, firstly, the protective cover 10 is driven to slide inside the mounting block 9 by the push-pull handle 13. When the protective cover 10 slides, the slider 11 is driven to move inside the slide groove. The slider 11 and the slide groove provide a guiding effect for the protective cover 10, so that the protective cover 10 maintains a correct movement trajectory when moving. By adjusting the protective height of the cradle, it can be ensured that the baby is in a safe and suitable position in the cradle, reducing the risk of falling caused by the baby trying to climb out or turn over. When the protective cover 10 moves to a suitable height, the threaded rod 15 is driven to rotate by turning the handle, and the fixing block 14 is threadedly connected to the threaded rod 15, so that the threaded rod 15 drives the clamping block 16 to approach the protective cover. The protective cover 10 is clamped and fixed by the clamping block 16, so that the protective cover 10 can be kept stable at a suitable height, reducing the risk of movement or shaking due to external force or the baby's movement, and improving the stability and reliability of the protective cover 10. When the clamping block 16 clamps the protective cover 10, the side of the metal plate 17 close to the protective cover 10 is set as a rough surface. The rough metal surface can increase the friction between the clamping block 16 and the protective cover 10, thereby further improving the clamping effect of the clamping block 16. When the clamping block 16 moves, the guide rod 18 provides an additional support point for the clamping block 16, so that the clamping block 16 can remain stable when moving.

[0044] Reference Figure 1 , Figure 6 and Figure 7 The reinforcement mechanism includes a mounting block 19 fixedly connected to the outer surface of the rotating rod 2, a horizontal plate 20 is fixedly connected to the outer surface of the mounting block 19, a sliding rod 21 is slidably connected inside the horizontal plate 20, one end of the sliding rod 21 is fixedly connected to a suction cup 22, an outer surface of the suction cup 22 is fixedly connected to an air outlet pipe 26, the air outlet pipe 26 is connected to the suction cup 22, and a driving member is provided at the end of the sliding rod 21 away from the suction cup 22.

[0045] Among them, the driving member includes a special-shaped block 23 fixedly connected to the end of the sliding rod 21 away from the suction cup 22, a special-shaped block 25 is arranged on the side of the special-shaped block 23 away from the sliding rod 21, the contact surface between the special-shaped block 23 and the special-shaped block 25 is arranged as an inclined surface, the special-shaped block 123 and the special-shaped block 25 are slidingly arranged, the side of the special-shaped block 25 away from the special-shaped block 123 is fixedly connected to the driving rod 24, and the end of the driving rod 24 away from the special-shaped block 25 is fixedly connected to the protective cover 10.

[0046] In addition, a second spring 28 is sleeved on the outer surface of the sliding rod 21 between the first special-shaped block 23 and the horizontal plate 20 .

[0047] When the protective cover 10 moves upward, the protective cover 10 will drive the driving rod 24 to move upward, and the movement of the driving rod 24 will drive the special-shaped block 2 25 to move upward. When the special-shaped block 25 moves upward, it will contact the special-shaped block 1. The contact surface between the special-shaped block 25 and the special-shaped block 1 23 is set as an inclined surface, so that the special-shaped block 1 23 is away from the special-shaped block 25, and the movement of the special-shaped block 1 will cause the sliding rod 21 to move, and the movement of the sliding rod 21 drives the suction cup 22 to approach the cabin. The suction cup 22 adsorbs the cabin surface to increase the supporting force between the cradle and the cabin, so that the cradle is more firmly fixed on one side of the cabin, and its movement when it is subjected to external vibration or impact is reduced, thereby improving the riding comfort and safety of the baby. After use, the negative pressure state inside the suction cup 22 can be released through the air outlet pipe 26, and then the protective cover 10 moves downward to make the special-shaped block 2 away from the special-shaped block 1. At this time, the elastic potential energy of the spring 28 is released, thereby driving the sliding rod 21 and the suction cup 22 to reset, which is convenient for the next use.

[0048] Working principle: first, align the two quick-connect components with the small holes set in the aircraft cabin, and then connect them with the aircraft cabin so that the top rod 4 is fixed on one side of the cabin, and then the staff rotates the rotating rod 2, and the rotating rod 2 rotates to drive the connecting block 3 to rotate inside the rotating block 1. The cradle cloth is pre-laid inside the cradle. After use, by taking out the rotating shaft 8, the rotating shaft 8 will squeeze the steel ball 7 when taking it out. The steel ball 7 and the engaging groove 27 are both set to an arc shape. When pulling out and rotating, the spring 6 can be compressed under the sliding action of the arc surface, so that the steel ball 7 is downwardly disengaged from the engaging groove 27. At this time, the limit on the rotating block 1 is released, so that the rotating rod 2 is rotated to the bottom of the top rod 4 for folding and storage, and the protective cover 10 is driven by the push-pull handle 13 to slide inside the mounting block 9. By adjusting the protective height of the cradle, it can be ensured that the baby is in a safe and suitable position in the cradle, reducing the risk of falling caused by the baby trying to climb out or turn over.

[0049] By clamping and fixing the protective cover 10, the protective cover 10 can be kept stable at a suitable height, reducing the risk of movement or shaking due to external force or the baby's movement, and improving the stability and reliability of the protective cover 10. When the protective cover 10 moves upward, the protective cover 10 will drive the suction cup 22 close to the cabin. The suction cup 22 adsorbs the surface of the cabin to increase the supporting force between the cradle and the cabin, so that the cradle is more firmly fixed to one side of the cabin, further improving the stability of the cradle.
