Folding mechanism and obstetric bed provided with same

Abstract

The invention discloses an obstetric bed. The obstetric bed comprises a bed body, two groups of storage rod devices and a butting device, wherein each group of storage rod device comprises a storage cavity, a holding rod and a folding mechanism; each folding mechanism comprises a lifting rod, a folding rod and a limiting structure, and each limiting structure comprises clamping grooves, a limitingrod, a movable groove and a limiting groove; the clamping grooves are positioned on the lifting rod, the clamping grooves are positioned on the periphery of a rotation through hole, and the clampinggrooves communicate with a cavity in the middle of the rotation through hole; the movable groove and the limiting groove are positioned at the inner side of the peripheral edge of a rotation shaft, acommunicating cavity is arranged between the movable groove and the limiting groove, and the limiting rod moves between the movable groove and the limiting groove through the cavity; and the lifting rod, the folding rod and the holding rod can contract and completely enter the storage cavity. Through the folding mechanisms, the holding rods on the obstetric bed can be folded and stored into the two sides of the obstetric bed, a user does not need to search the additional space for storing the holding rods, the operations of searching for and carrying the holding rods are not needed, so that the assembly and use of the holding rods are convenient and rapid, and a birthattendant can freely use the holding rods according to the demands of puerperae.
