DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes in detail the specific embodiments of the present technical solution with reference to the drawings.

[0026] As Figure 1As shown in the figure, a rocking cradle with foldable casters includes a cradle assembly 1, a cradle support 2, a storage basket 33, and several cradle casters 3. The cradle assembly 1 and the cradle casters 3 are both arranged on the cradle support 2. The cradle assembly 1 is used to place a baby. The cradle casters 3 can be extended to move the cradle or retracted to rock the cradle.

[0027] Specifically, the cradle assembly 1 includes a cradle placement rack 15, a cradle main body 16, and a lifting structure 17. The cradle main body 16 is arranged inside the cradle placement rack 15. The cradle placement rack 15 is arranged on the cradle support 2 through the lifting structure 17. The cradle support 2 includes a support rod 10, a connecting piece 13, and an arc-shaped bottom rod 12. The upper end of the support rod 10 is connected to the lifting structure 17, and the lower end is connected to the arc-shaped bottom rod 12 through the connecting piece 13. The cradle casters 3 are movably arranged in an installation groove 5 opened at the lower end of the support rod 10 through a hinge structure 4.

[0028] Furthermore, the connection mode between the lifting structure 17 and the support rod 10 adopts a plug-in fixed connection mode. The support rod 10 is hollow inside and has a plug-in port 11 at the top. The lower end of the lifting structure 17 can be directly plugged into the plug-in port 11 to achieve the fixation of the two.

[0029] As Figures 2 - 4 shown in the figure, the hinge structure 4 includes a hinge part 6 and a pin shaft. The cradle caster 3 is plugged into the lower end of the hinge part 6. A waist-shaped hole 7 is opened on the hinge part 6. The pin shaft is plugged into the installation groove 5 and movably placed in the waist-shaped hole 7. Therefore, the hinge part 6 can move up and down in the installation groove 5 without detaching from the installation groove 5 and can rotate in the installation groove 5.

[0030] Specifically, the upper end of the hinge part 6 has a locking part 8. There is a space in the installation groove 5 for the locking part 8 to move. A convex rib 9 is arranged on the inner wall of the installation groove 5. The shape of the convex rib 9 is that the upper and lower end faces protrude, while the middle part is recessed. The recess in the middle is used to avoid the rotating hinge part 6. When the cradle is statically placed, the upper end face of the convex rib 9 cooperates with the groove wall of the installation groove 5 to form a limiting cavity. At this time, due to the self-weight of the cradle, the side surface of the locking part 8 abuts against the upper end face of the convex rib 9 and enters the limiting cavity. Therefore, the cradle caster 3 cannot rotate, and the cradle can be moved through the cradle caster 3; when the cradle support 2 is lifted, due to the weight of the cradle caster 3, the hinge part 6 moves downward and the locking part 8 disengages from the convex rib 9. At this time, by externally rotating the hinge part 6 to reach a certain position and then pushing the hinge part 6 downward, the locking part 8 abuts against the lower end face of the convex rib 9, and the lower end face of the convex rib 9 cooperates with the groove wall of the installation groove 5 to form a limiting cavity, and the locking part 8 falls into the limiting cavity and is fixed, realizing that the cradle caster 3 is completely retracted inside the cradle support 2, and the arc-shaped bottom rod 12 of the cradle support 2 is in direct contact with the ground. This not only ensures the swing of the cradle but also prevents the casters from being knocked.

[0031] As Figure 5 andFigure 6 As shown in Figure 6 , the lifting structure 17 includes a connecting sleeve 18, a connecting shell 20, a movable member 21, a locking member 24, and a return spring. The connecting sleeve 18 is a connecting component that connects the rocking bed placement frame 15 and the support rod 10. A plurality of vertically arranged clamping grooves 19 are formed on the inner surface of the connecting sleeve 18, and the clamping grooves 19 are used to cooperate with other components to achieve lifting. The connecting shell 20 is arranged on both sides of the rocking bed placement frame 15. The upper end of the connecting shell 20 is connected to the rocking bed placement frame 15, and the lower part is inserted into the connecting sleeve 18. The inside of the connecting shell 20 is hollow to form an installation space. The movable member 21 is movably arranged in the installation space and partially extends out of the connecting shell 20. The user can lift the movable member 21 outside the connecting shell 20 to achieve lifting. The lower end of the movable member 21 has a first movable inclined surface 22 and a movable groove 23 for cooperating with the locking member 24. The locking member 24 is movably placed in the movable groove 23, and the lower end has a second movable inclined surface 25. The front end of the return spring abuts against the locking member 24, and the rear end abuts against the connecting shell 20, so as to make the locking member 24 always have a movement tendency towards the clamping groove 19.

[0032] Specifically, the movable member 21 and the locking member 24 are limited in the connecting shell 20, and the locking member 24 is arranged through the movable groove 23 of the movable member 21. At the same time, the first movable inclined surface 22 and the second movable inclined surface 25 abut against each other. When the movable member 21 is lifted, the first movable inclined surface 22 and the second movable inclined surface 25 cooperate with each other to realize the horizontal movement of the locking member 24. After the locking member 24 moves horizontally, it can withdraw from the clamping groove 19. When the locking member 24 withdraws from the clamping groove 19, it can lift synchronously with the movable member 21. And when the two reach the specified position, they can extend out of the clamping grooves 19 at different heights again, so as to realize the lifting of the rocking bed placement frame 15.

[0033] Furthermore, in order to increase the stability of the lifting structure 17, the lifting structure 17 further includes a buckle plate 26 and a fixing sleeve 27. The buckle plate 26 is arranged in the installation space, and its shape is adapted to the movable member 21 to limit the horizontal movement of the movable member 21. The fixing sleeve 27 is sleeved outside the connecting shell 20 to limit the buckle plate 26 and the connecting shell 20. Through holes 28 for the locking member 24 to pass through are formed on both the buckle plate 26 and the fixing sleeve 27. A limiting portion 29 protrudes from the fixing sleeve 27, and a limiting groove 30 is recessed in the connecting sleeve 18. When the fixing sleeve 27 is placed in the connecting sleeve 18, the limiting portion 29 is placed in the limiting groove 30.

[0034] Even further, a slideway 31 is formed on the connecting sleeve 18, and a slider 32 is arranged on the rocking bed placement frame 15. When adjusting the height of the rocking bed placement frame 15, the slider 32 is movably placed in the slideway 31. The arrangement of the slider 32 and the slideway 31 can ensure the overall stability of the rocking bed when adjusting the height.
