the underframe 3 is connected with a plurality of bottom corner assemblies 21;
the linkage assembly 4 is arranged between any top corner assembly 12 and the upper frame rod assembly 11 and the side bracket 2 connected with the top corner assembly;
when the frame is unfolded, the upper frame rod assemblies 11 enclose a fixed polygonal frame, each group of side brackets 2 and the upper frame rod assemblies 11 opposite to the side brackets form a fixed inverted isosceles triangle frame together, the bottom angle assemblies 21 are positioned at the vertex angles of the isosceles triangle frame, and the bottom frame 3 unfolds the bottom angle assemblies 21 towards the direction far away from the center;
when the foldable children bed frame is in a folded state, the underframe 3 is folded towards the center and drives the bottom corner component 21 to move towards the center, the bottom corner component 21 drives the lower end of the side rod piece 22 to move towards the center of the lower part, and the upper end of the side connecting rod 22 drives the top corner component 21 and the upper frame rod component 11 to move towards the center of the upper part through the linkage component 4, so that the whole foldable children bed frame is folded.
Specifically, the upper frame 1 is located on the upper portion of the foldable children's bed frame, and four sets of upper frame bar assemblies 11 are provided. In the unfolded state, as shown in fig. 1, the four sets of upper frame rod assemblies 11 are located on the same horizontal plane, and enclose a rectangular frame structure. The adjacent upper frame rod assemblies 11 are connected through top corner assemblies 12, and the top corner assemblies 12 are located at four corners of the rectangular frame structure. In the collapsed state, as shown in fig. 5, the four corner assemblies 12 are folded together, and the four sets of upper frame bar assemblies 11 are collapsed in the vertical direction.
In the deployed state, the side bar members 22 lie in a vertical plane, as shown in figure 2. A bottom corner module 21 corresponds longitudinally to the middle of each upper frame bar module 11 and two side bar members 22 extend obliquely upwardly from the bottom corner module 21 along the longitudinal plane and are connected to the two top corner modules 12, respectively. Each set of side frame 2 and the upper frame bar assembly 11 opposite thereto together form a fixed inverted isosceles triangle frame, the base angle assembly 21 is located at the top angle of the isosceles triangle frame, and the isosceles triangle frame forms a stable supporting structure, so that the expanded bed frame is more stable. Four bottom corner assemblies 21 are used to contact the ground to support the entire bed frame.

The upper cloth pocket 61 hides the upper frame rod assembly 11, the upper half section of the side rod member 22 and the linkage assembly 4 inside, so that the appearance is attractive, and the infant is prevented from being bruised.
The lower half of the side rod 22 penetrates through the upper cloth pocket 61, is positioned outside the lower cloth pocket 62, and is connected with the bottom corner assembly 21.
When lower floor's cloth pocket 62 expanded state, the suspension is in the top of base angle 3, and the base 33 of base angle 3 has played the effect of support to lower floor's cloth pocket 62, and the user operation of being convenient for can be penetrated to pull ring 34 in lower floor's cloth pocket 62.
In this embodiment, when the upper frame rod assembly 11 is folded down in the longitudinal direction, the flexible fabric of the upper cloth bag 61 is not tightened, and the shoulder assembly 111 is not easily worn. Similarly, the linking component 4 is folded along the longitudinal direction during the folding process, so that the flexible woven fabric is not easily abraded.
Whole children's folding bed is folding the in-process of folding up, presents the state of following the central shrink of orientation all around, and folding bed's lateral wall folds up along vertical plane all the time, can not produce outside bellied closed angle structure, avoids colliding operating personnel to and the damage to the flexibility is weaved, prolongs folding bed's life.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
