The driving assembly is disposed between the first slider 71 and the rotating handle 61 on each side, respectively. Specifically, the driving assembly on one side includes the swing link 72 and the movable member 73, and the driving assembly on the other side includes the second sliding member 74. Thus, when the first locking structure enables the rotating handle 61 to rotate relative to the top corner 32 in a locking state, the swing rod 72 and the movable piece 73 on one side can be driven to rotate relative to the top corner 32 at the same time, and the second sliding piece 74 on the other side can be driven to slide relative to the top corner 32, so that the first sliding pieces 71 on two sides are driven to slide relative to the top corner 32, two adjacent frame surrounding rod assemblies rotate relative to the top corner 32 around the axis of the two adjacent frame surrounding rod assemblies at the same time, and the first locking structures on the two adjacent frame surrounding rod assemblies are unlocked at the same time. Like this, this crib as long as set up a twist grip 61 respectively on two apex angles 32 that the diagonal angle set up, thereby can be through operating two twist grips 61 respectively with whole first locking structure unblocks for the unblock operation of crib is more convenient.

The upper enclosing frame assembly further comprises a resetting assembly used for driving the first sliding piece 71 to reversely slide and reset when the upper enclosing frame assembly is unfolded, the resetting assembly comprises an elastic piece 81 and an elastic sleeve 82, one end part of the elastic piece 81 is arranged on the elastic sleeve 82, the other end part of the elastic piece 81 is arranged on the first enclosing frame rod 11, the elastic sleeve 82 can be arranged in the first enclosing frame rod 11 in a sliding mode along the extending direction of the axial lead of the enclosing frame rod assembly, and the elastic sleeve 82 is abutted against the first sliding piece 71 to be matched.

In the process of operating the rotating handle 61 to enable the first sliding piece 71 to slide relative to the top corner 32 to unlock the first locking structure, the whole reset assembly rotates around the axis of the reset assembly along with the frame surrounding rod assembly, and meanwhile, the first sliding piece 71 drives the elastic sleeve 82 to slide along the axis of the frame surrounding rod assembly to enable the elastic piece 81 to be compressed. When the crib is unfolded and the rotating handle 61 is rotated reversely, the first sliding part 71 can be driven to slide reversely and reset, and meanwhile, the elastic force generated by the elastic part 81 recovering the elastic deformation enables the elastic sleeve 82 to drive the first sliding part 71 to slide reversely and reset, so that the rotating handle 61 is easier, and the unfolding operation of the crib is more convenient.

When the child bed of the present embodiment is folded from the unfolded state, as in embodiment 1, the two handles 61 are respectively operated, and the first sliding member 71 is made to slide relative to the top corner 32 by the driving assembly, so that the entire enclosure frame rod assembly is rotated around its own axis, and each first locking structure is unlocked, and the second locking structure is also unlocked. When the child bed is folded, the first sliding part 71 drives the first frame enclosing rod 11 to rotate downwards around the first shaft 41 relative to the top corner 32, the adaptor 9 drives the second frame enclosing rod 12 to rotate downwards around the first shaft 41 relative to the top corner 32, so that the first frame enclosing rod 11 and the second frame enclosing rod 12 are closed, the rest is the same as in embodiment 1, the folding process is shown in fig. 26 and 27, and the final folding process is shown in fig. 28 and 29.
