Said side support 11 of each side comprising
The surrounding rod frame 111 comprises a surrounding rod body 111a, a sliding seat 111b fixed at the front part of the surrounding rod body 111a, and a fixed seat fixed at the rear part of the surrounding rod body 111a, wherein a guide channel is formed on the sliding seat 111 b;
the upper part of the front supporting frame 112 is pivotally connected with the sliding seat 111b around the first axis X1;
the upper part of the rear support frame 113 is pivotally connected with the fixed seat around a second axis X2;

When the front bracket 112 rotates around the first axis X1 and folds toward the middle of the surrounding bar frame 111, the third axis X3 moves clockwise around the first axis X1, so that under the action of the linkage rod 114, the fourth axis X4 is pulled to move counterclockwise around the second axis X2, which causes the rear bracket 113 to rotate around the second axis X2 and also fold toward the middle of the surrounding bar frame 111.
The front end parts of the surrounding rod frames 111 on the two sides, the rear end parts of the surrounding rod frames 111, the front supporting frames 112 and the rear supporting frames 113 are fixedly connected into a whole through transverse supporting rods.
In the present embodiment, the third axis X3 is located above the first axis X1, and the fourth axis X4 is located below the second axis X2. When the bed frame 1 is in the open position, the connecting line of the axes of the first axis X1 and the second axis X2 intersects the connecting line of the axes of the third axis X3 and the fourth axis X4. The locking mechanism may be provided at a plurality of positions, for example, any one of the first axis X1, the second axis X2, the third axis X3 and the fourth axis X4 may be used to lock the entire bed frame, the positions of the above axis points are set so that the linkage rod 114 can be slidably provided on the surrounding rod frame 111, and the surrounding rod frame has a plurality of positions with different heights by locking the relative positions of the two.
In this embodiment, the linkage rod 114 is slidably disposed on the surrounding rod frame 111, and the locking mechanism 2 is disposed between the linkage rod 114 and the surrounding rod frame 111.

The infant folding bed has a high position mode and a low position mode in an opening position.
When the infant folding bed is in the high position mode, as shown in fig. 1 and 3, the front support frame and the rear support frame are spread to the limit position in a splayed shape and locked by the locking mechanism.
When the crib is switched from a high-position mode to a low-position mode, after the crib is unlocked by an unlocking control mechanism, the front support frames 112 rotate around the first shaft X1 and move towards the middle of the surrounding rod frame 111, the third shaft X3 moves around the first shaft X1 clockwise, so that under the action of the linkage rod 114, the fourth shaft X4 is pulled to move around the second shaft X2 anticlockwise, the rear support frames 113 rotate around the second shaft X2 and also move towards the middle of the surrounding rod frame 111, the front support frames and the rear support frames are crossed to form an X shape, the height of the surrounding rod frame is reduced by adjusting the crossed angle of the X shape, the locking mechanism locks again to achieve the low-position mode, the distance between the rear support frames on two sides is smaller than the distance between the front support frames on two sides, and the rear support frames can pass through the front support frames on two sides conveniently.
In the process of switching from the high-position mode to the low-position mode, the surrounding rod frame is always in a horizontal state.
And unlocking again, pressing the enclosure frame downwards through the unlocking control mechanism, and continuing to adjust the X-shaped cross angle until the enclosure frame, the front support frame and the rear support frame are tightly closed together, so that the folding of the infant folding bed is finished, and the folded infant bed is flat, has a small structural volume and is convenient to carry and store.
In this embodiment, the transverse brace between the front brackets 112 at two sides and the transverse brace between the rear brackets 113 at two sides are respectively located at the lower end portion and are arched downward to form the arc-shaped rocking bar 12, and the lower end portions of the front brackets 112 and the rear brackets 113 are movably provided with the anti-rocking member 112a, so that when the anti-rocking member is pulled upward off the ground, the infant folding bed can be used as a rocking bed.
Example two:
not shown, the difference between the second embodiment and the first embodiment is that: the front ends of the surrounding rod frames 111, the rear ends of the surrounding rod frames 111, the front brackets 112 and the rear brackets 113 on two sides are respectively connected through folding rods, so that when the bed frame is folded to be in a flat state, the bed frame can be further folded transversely to reduce the volume, and the folding rods between the front ends of the surrounding rod frames 111 or the folding rods between the rear ends of the surrounding rod frames 111 are provided with unlocking control mechanisms 3 for controlling the locking mechanisms 2.
