The first embodiment is as follows:

as shown in fig. 4, a locking device for a children's frame for switching a link assembly 10 of a bottom frame 20 of a children's frame connected to the locking device between an unfolded fixed state and a folded state, includes a mounting base 1, a cover plate 2, and a rotation member 3, the cover plate 2 being fixed to the mounting base 1, the rotation member 3 being installed between the mounting base 1 and the cover plate 2;

the rotary member 3 comprises at least a first position and a second position:

when the rotating part 3 rotates to the first position, the locking device is in a locking state, and the connecting rod assembly 10 is locked on the mounting seat 1 in an unfolding and fixing state;

when the rotating member 3 rotates to the second position, the locking device is in an unlocked state, and the connecting rod assembly 10 can rotate relative to the mounting base 1 and is folded to a foldable state.

Specifically, a circular cavity is arranged in the center of the mounting seat 1, the cover plate 2 is approximately disc-shaped, the cover plate 2 is buckled at the top of the mounting seat 1 and is fixedly connected with the mounting seat 1, and the cover plate 2 is used for sealing the cavity of the mounting seat 1.

The rotating piece 3 is arranged in a circle center cavity of the mounting seat 1 and can rotate in the cavity, and the switching between the locking state and the unlocking state is realized.

At least one connecting rod 101 of the connecting rod assembly 10 is inserted into the mounting 1 and protrudes into the cavity of the mounting 1.

When the rotation piece 3 is rotated to the first position, the locking device is in the locked state, the link 101 interferes with the rotation piece 3, and the rotation piece 3 locks the link 101 so that the link 101 is kept in the unfolded fixed state and cannot be rotated.

As shown in fig. 1, the link 101 is connected to the side bracket 30, and the side bracket 30 is connected to the upper frame 40. The locking device locks the link assembly 10 in the unfolded fixed state of the cot, in which the four links 101 are extended in the horizontal direction, and the side brackets 30 and the upper frame 40 are unfolded to the maximum.

When the rotating member 3 rotates to the second position, the locking device is in an unlocked state, the rotating member 3 is separated from the connecting rod 101, and the connecting rod 101 can be rotatably folded relative to the mounting base 1 to a foldable state.

As shown in FIG. 3, when the bottom frame 20 is lifted up, the link 101 rotates downward, and the link 101 folds the side frames 30 and the upper frame 40.
