Description

TECHNICAL FIELD

[0001] The utility model relates to the field of children's bed, and specifically relates to a novel folding baby bed. BACKGROUND

[0002] Baby bed refers to the bed used for infants, and the baby beds of various styles are available in the market, and the functions and prices thereof are also quite different. The existing baby beds can be roughly divided into fixed type, folding type, cradle type and the like according to the types, and the folding type baby bed is convenient to carry and occupies small space when not in use, and thus is favored by the majority of consumers. The existing folding type baby bed is relatively cumbersome to operate when folding, and for example, the patent with the Chinese publication number CN118415483A discloses a folding baby bed. When the folding baby bed is not needed (i.e. the folding baby bed needs to be stored), an unlocking switch is operated, the joint lock is unlocked by the unlocking switch, the first upper surrounding rod group and the second upper surrounding rod group are released by the joint lock, and then the user presses down the upper bed surrounding, and simultaneously pulls up the lower bed surrounding. At this time, the first upper surrounding rod group and the second upper surrounding rod group are synchronously turned down and approach each other, and the first lower surrounding rod group and the second lower surrounding rod group are synchronously turned up and approach each other, until the first upper surrounding rod group and the second upper surrounding rod group and the first lower surrounding rod group and the second lower surrounding rod group are folded and close to each other, and the first bed leg assembly and the second bed leg assembly are also moved towards each other and close to each other under the pulling of the upper bed surrounding and the lower bed surrounding, so that the folding baby bed is folded into a compact square structure.
