The newborn tray structure also comprises an operating component mounted on the frame body and locking or unlocking the frame body relative to the swivel frame body. The frame body is mounted on a movable delivery cart by adjusting the frame body up and down via a connecting rod.

[0007] Preferably, the swivel seat body comprises a swivel shaft extending in a vertical direction and a turntable fixed on the top of the swivel shaft, wherein the swivel shaft is rotatably arranged in the seat body via a bearing.

[0008] Furthermore, the seat body is recessed inward from the top to form a mounting hole, the bearing is fixedly installed in the mounting hole, and the rotary shaft matches the bearing and the lower part is inserted into the mounting hole.

[0009] According to a specific implementation and preferred aspect of the utility model, an insertion hole perpendicular to and connected to the mounting hole is further provided on the seat body, and the operating component is installed in the insertion hole.

[0010] Preferably, the operating component includes a first locking block and a second locking block respectively inserted into the insertion hole and located on opposite sides of the rotating shaft, and a threaded locking pin inserted into the first locking block and the second locking block, wherein the first locking block and the second locking block are relatively close to each other to contact and clamp the rotating shaft to form a lock, that is, by rotating the threaded locking pin, the first locking block and the second locking block are relatively close to each other or separated to lock and unlock.

[0011] In some specific embodiments, arc-shaped notches are formed at the ends of the first locking block and the second locking block facing the rotating shaft, respectively. When in a locked state, the center of the arc-shaped notch coincides with the center of the rotating shaft and is clamped on opposite sides of the rotating shaft.

[0012] Preferably, in the locked state, the first locking block and the second locking block remain spaced apart.

[0013] In some specific embodiments, the circumference of the rotary shaft is 7 to 10 times the length of the arc formed by the arc-shaped notch. Generally, 8 to 9 times is sufficient.

[0014] According to another specific implementation and preferred aspect of the utility model, the circumferential contour of the turntable is aligned with the circumferential contour of the seat body in the vertical direction to avoid accidental pinching caused by rotation dislocation; at the same time, the handle bar is fixed to the center of the turntable from the middle, and the two ends of the handle bar are exposed on the opposite sides of the turntable and extend upward. This layout is convenient for two-handed operation to implement angle adjustment.

[0015] In addition, the supporting frame includes two support rods which are symmetrically arranged about the rotation center of the rotating seat body, wherein the support rods are arranged obliquely from bottom to top.

[0016] Another technical solution of the utility model is: a delivery cart, which includes a cart, a lifter installed on the cart, a connecting rod passing through the cart from the lifting end of the lifter, a tray structure fixed to the outer end of the connecting rod, and an auxiliary lamp installed on the cart and capable of being adjusted in a horizontal plane according to the position of the tray structure, wherein the tray structure is the above-mentioned neonatal tray structure, the auxiliary lamp is located above the tray, and forms an illumination area covering the entire tray structure.

[0017] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:
