When the secondary support rod 220 drives the direction-changing rod 230 to extend above the main support tube 210, the direction-changing rod 230 slides in contact with the arched wall 211 to automatically adjust the unfolding angle of the supporting hanging rod 120; thereby adjusting the matching position of the hanging rod 120 and the sling 110, so that when the mother's buttocks are supported on the sling 110, both feet are placed on the two hanging rods 120; wherein a silicone pad is bonded to the top surface of the hanging rod 120 so that the ankles can be placed comfortably; The rear side walls of the bed body 100 are provided with limit pins 130, and the side walls of the main support tube 210 facing the bed body 100 are provided with oblique ribs 214, which are used to strengthen the support strength of the main support tube 210; the bottom side walls of the oblique ribs 214 are provided with limit holes 215, and the limit pins 130 are plugged and matched with the limit holes 215, so that the main support tube 210 forms a stable supporting state when it is erected; The two side walls at the rear end of the bed body 100 are fixedly connected with a fixing sleeve 101, and the limit pin 130 is plugged into the fixing sleeve 101. The fixing sleeve 101 and the limit pin 130 are both made of iron; a lifting ring 102 is fixedly connected to the corner of the bottom surface of the rear end of the bed body 100, and the lifting ring 102 is also made of iron; a hinged platform 213 is vertically provided on the bottom side wall of the main support tube 210, and the hinged platform 213 is rotatably connected to the lifting ring 102 by a bolt, and the other end of the bolt is threadedly connected with a nut, so that the main support tube 210 can be stable after turning up or down.

[0035] Specifically, the direction-changing rod 230 is composed of a direction-changing tube 231 and a telescopic rod 232, so that the direction-changing rod 230 can adjust its own length and change the hanging height of the hanging rod 120; a slot 221 connected to the direction-changing tube 231 is provided at the top of the secondary support rod 220 and toward the arch wall 211, and a hinge block 223 is provided at the bottom of the slot 221. A round protrusion 2311 hinged to the hinge block 223 is provided at the bottom end of the direction-changing tube 231, so that when the direction-changing tube 231 is rotated and connected with the slot 221, it can be inserted into the main support tube 210 together with the secondary support rod 220 for storage, and the secondary support rod 220 is closed by designing a cover that is engaged with the top end of the main support tube 210, so that the main support tube 210 can be rotated down to the bottom of the bed 100 for storage.

[0036] Furthermore, a plurality of slots 222 are provided at equal intervals in the vertical side walls of the card slot 221. Support straps 111 made of elastic material, such as elastic bands, are sewn on both sides of the sling 110, so that the sling 110 can support the parturient comfortably and automatically adapt to the support height; the upper end of the support strap 111 is tightly sleeved on the latch 112, and the latch 112 is plugged and matched with the slot 222, so that the sling 110 is easy to disassemble and assemble; the main support tube 210, the auxiliary support rod 220, the change-direction rod 230 and the latch 112 are all made of chrome-plated iron metal parts, so that they have the strength to support the weight of the parturient; The hanging rod 120 is hook-shaped and the top end thereof is rotatably connected with a hanging sleeve 121 , and the hanging sleeve 121 is sleeved and matched with the top end of the telescopic rod 232 , so that the hanging rod 120 is easy to assemble and disassemble and stable to install.

[0037] Furthermore, a positioning hole 2312 is provided on the top side wall of the deflection tube 231, and a plurality of through holes 2321 are provided on the side wall of the telescopic rod 232 at equal intervals. A plug post 233 is inserted into the positioning hole 2312 and one of the through holes 2321, so that the telescopic rod 232 remains stable when adjusting the extension length. A threaded hole 2322 threadedly connected to the plug post 233 is provided at the top center of the telescopic rod 232, so that the plug post 233 can be stored and used at any time, and the telescopic rod 232 can be pulled out of the deflection tube 231 by pulling the plug post 233.

[0038] Furthermore, a clearance opening 212 is provided at the bottom end of the main support tube 210, and the bottom end of the threaded rod 250 is placed at the clearance opening 212. A recessed hole threadedly connected to the upper section of the threaded rod 250 is provided at the bottom end of the secondary support rod 220, so that the bottom end of the threaded rod 250 can be grasped and rotated to control the lifting and lowering movement of the secondary support rod 220 in the main support tube 210; the bottom of the threaded rod 250 is tightly sleeved on the bearing and the outer wall of the bearing is fixedly connected to the inner wall of the main support tube 210, so that the threaded rod 250 can be positioned and rotated.

[0039] In addition, in order to further increase the strength of the pair of main support tubes 210 in supporting the parturient, a rod hole 224 is opened at the top of the secondary support rod 220, and a fixed tube rod 240 is inserted into the rod hole 224. The fixed tube rod 240 is a metal component made of iron, which improves its strength; the bottom end of the fixed tube rod 240 is rotatably connected to a rotating block 243, and the pair of fixed tube rods 240 extend out from the top of the rod hole 224 and rotate to a horizontal position, and then connect with each other, so that when the parturient is supported by the sling 110, the pair of fixed tube rods 240 can resist the pulling force of the parturient on the top of the pair of main support tubes 210, and the oblique ribs 214 of the main support tube 210 support it to ensure that the main support tube 210 stably supports the parturient for delivery.

[0040] Furthermore, a pair of side walls of the rod hole 224 are provided with slide grooves 225, and sliders 244 are symmetrically provided on both sides of the bottom of the rotating block 243. The pair of sliders 244 and the pair of slide grooves 225 are correspondingly inserted and slidable, wherein a blocking bar for blocking the sliders 244 is embedded at the top of the slide groove 225, so as to prevent the rotating block 243 from being pulled off when the fixed pipe rod 240 is pulled out; A limit block 241 is vertically provided on the side wall of the outer end of the fixed tube rod 240. The limit block 241 is a triangular block structure, so that when a pair of fixed tube rods 240 are rotated to horizontally dock, the two limit blocks 241 are used to abut and prevent the pair of fixed tube rods 240 from bending downward, so as to resist the downward pressure of the parturient; the outer end of one of the fixed tube rods 240 is provided with a clamping block 242, and the outer end of the other fixed tube rod 240 is provided with a groove that is clamped with the clamping block 242, so that the pair of fixed tube rods 240 will not be misaligned and pulled apart front and back after docking, thereby playing a role in stabilizing the docking.

[0041] When the hanging delivery support device for the delivery room of the present invention is in use, the expectant mother lies on the bed 100 and places her buttocks at the rear end of the bed 100, then flips up the two main support tubes 210 to stand vertically above the two sides of the bed 100, and then grasps the bottom end of the threaded rod 250 to rotate and control the secondary support rod 220 to rise in the main support tube 210. In the process of the secondary support rod 220 driving the direction-changing rod 230 to extend above the main support tube 210, the direction-changing rod 230 is manually unfolded and slidably contacts with the arch wall 211 to automatically adjust the unfolding angle of the supporting hanging rod 120; then the sling 110 is hung between a pair of secondary support rods 220, and the hanging rod 120 is hung on the top of the direction-changing rod 230, thereby adjusting the matching position of the hanging rod 120 and the sling 110, so that when the mother's buttocks are supported on the sling 110, both feet are placed on the two hanging rods 120, thereby exposing the perineum for delivery.

[0042] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
