Technical Field
The utility model relates to a crib middle bed.
Background
The traditional infant nursing mainly adopts a bed for the infant and parents to sleep together, and has the advantages of convenient nursing and convenient diaper changing. Under the common conditions, adults are fatigued when sleeping at night, the face of children is easily covered by quilts, or the limbs of adults press infants, so that the infants lack oxygen, and unsafe factors are brought.
In order to avoid the above problems, the crib has come to be transported. At present, cribs for use in a bed are also called "bed-in-bed" and are made foldable for easy carrying and storage. The common folding crib comprises two lower enclosing pipes and a plurality of upper enclosing pipes, wherein all the upper enclosing pipes are coaxially pivoted with the lower enclosing pipes, and the upper enclosing pipes are positioned between the two lower enclosing pipes. The two lower enclosing pipes are unfolded downwards to form a mounting plane for placing the baby mattress, and the plurality of upper enclosing pipes are erected above the mounting plane and are used for supporting a mosquito net which surrounds the baby crib.
However, the relative positional relationship between the upper and lower tubes is maintained only by the friction force between the joints that are coaxially pivoted, and such a structure is extremely weak and unstable, and if the upper tube collapses downward, it is impossible to protect the infant, which is likely to cause a safety accident.
