Embodiment 1
[0036] Such as Figures 1 to 7 The delivery bed shown includes a bed body, two sets of receiving rod devices and a docking device 4, and the two sets of receiving rod devices are located on both sides of the bed body.
[0037] The storage rod device includes a storage chamber 5, a grip rod 3 and a folding mechanism; the docking device 4 is used to dock two grip rods 3 and keep them coaxial; the grip rod 3 is connected to the folding rod 2 in rotation; retractable.
[0038] The folding mechanism includes a lifting rod 1 and a folding rod 2, the lifting rod 1 includes a rotating through hole 10, the folding rod 2 includes a rotating shaft 20, and the rotating shaft 20 is pivotally connected in the rotating through hole 10, and the folding rod 2 is folded and moved relative to the lifting rod 1; Folding mechanism also comprises position-limiting structure, and position-limiting structure comprises draw-in groove 11, limit bar 60, movable groove 21 and position-limiting groove 22...
Embodiment 2
[0050] This embodiment is based on embodiment 1, and the folding rod 2 is further improved, and the rest are the same as or similar to embodiment 1.
[0051] Such as Figure 8 As shown, the folding rod 2 is a telescopic rod body. The folding rod 2 includes a first rod body 2a and a second rod body 2b. The second rod body 2b has a stepped cylinder with a small diameter. From 2b1. The surface of the first rod body 2a is provided with a plurality of limiting holes 2a1, which can be sleeved on the surface of the stepped cylinder and slide relative to the second rod body 2b.
[0052] When it is necessary to adjust the length of the folding rod 2, by pressing down the limit protrusion 2b1 so that the limit protrusion 2b1 retracts and breaks away from the position limit hole 2a1, the first rod body 2a and the second rod body 2b move to the fold required by the puerpera. The length of the rod 2 is fixed by snapping the limiting protrusion 2b1 into the limiting hole 2a1 again.
