Description

Technical Field

[0001] The utility model relates to the technical field of folding beds, in particular to a leg connecting seat and a supporting frame. Background Art

[0002] Existing cribs are primarily used to confine infants, providing a safe space for play and sleep. There are many types of cribs on the market, including folding beds, cradles, and infant care beds. Folding cribs are increasingly popular due to their foldability and compact storage footprint.

[0003] The existing foldable baby crib frame consists of an upper frame, a lower frame, and struts pivotally connected at the four corners. Joints between the frames allow the crib to be expanded or folded. To fold, the upper and lower frames are unlocked, allowing them to rotate toward the center. This reduces the crib's footprint and makes it easier to carry and store. However, existing foldable baby cribs may have the following disadvantages:

[0004] First, after folding, the support part or support seat at the bottom (the middle position at the bottom, which realizes the folding function) is higher than the upper connecting part or upper leg connecting parts (located at the four corners at the top). In this way, after folding, it is easy to press the support part or support seat, affecting the use of the child crib;

[0005] Secondly, the fence cloth of the folding bed is currently set on the bottom of the column and needs to be fixed by a fixing rod (for example, bolts are currently used) and a gasket. Specifically, the fixing rod is passed through the gasket, the fence cloth and the column to fix it to prevent the fence cloth from moving up. When this structure is adopted, the gasket is small and the assembly is more cumbersome; and since the column is cylindrical, the gasket overlaps with one side of the column and needs to be provided with an arc groove that matches the column, which is costly.
