Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, a patient sitting assisted training structure based on a hospital bed includes a bed board 1, a telescopic mechanism 2 at the bottom of the bed board 1, and a lifting mechanism 3 at the bottom of the bed board 1.

[0030] The telescopic mechanism 2 includes a box 21 that is slidably connected to the bottom of the bed board 1. Two symmetrically distributed T-shaped blocks 22 are fixedly connected to the top of the box 21, and a threaded rod 23 is rotatably connected to the inner wall of the back of the box 21.

[0031] The lifting mechanism 3 includes two compartments 31 that are symmetrically distributed and fixedly connected to the bottom of the bed board 1. The bottom of the bed board 1 is fixedly connected to two symmetrically distributed connecting seats 32, and the interior of each of the two connecting seats 32 is fixedly connected to two symmetrically distributed connecting plates 33.

[0032] like Figures 1-3 As shown, a support plate 24 is threadedly connected to the outer side of the threaded rod 23, a housing 25 is fixedly connected to the right side of the housing 21, a rotating rod 26 is rotatably connected to the inner wall of the back of the housing 25, pulleys 27 are fixedly connected to the outer sides of both the rotating rod 26 and the threaded rod 23, a belt 28 is driven to the outer sides of the two pulleys 27, and an installation assembly 29 is provided at the bottom of the housing 21.

[0033] It should be noted that when the rotating rod 26 is rotated, the rotating rod 26 drives the threaded rod 23 to rotate through the pulley 27 and the belt 28. The threaded rod 23 drives the support plate 24 to move forward and extend from the inside of the box 21, so that the patient's feet can step on the support plate 24, thus facilitating sitting training.

[0034] like Figures 1-3 As shown, the bottom of the bed board 1 has two symmetrically distributed T-shaped grooves, and the T-shaped block 22 is adapted to the T-shaped groove.

[0035] It should be noted that this achieves longitudinal fixation of the enclosure 21, increasing the stability of the enclosure 21 after installation.

[0036] like Figures 1-4 As shown, the mounting assembly 29 includes a box 291 fixedly connected to the bottom of the bed board 1. A positioning rod 292 is slidably connected inside the box 291. A positioning plate 293 is fixedly connected to the outside of the positioning rod 292. A spring 294 is sleeved on the outside of the positioning plate 293.

[0037] It should be noted that when the positioning rod 292 is pulled, the positioning rod 292 drives the positioning plate 293 to move to the left to compress the spring 294. At the same time, the positioning rod 292 is pulled out from the positioning groove on one side of the box 21. Then, the box 21 is pulled forward to pull out the T-shaped block 22 from the inside of the T-shaped groove, which facilitates the quick disassembly of the box 21.

[0038] like Figures 1-4 As shown, a positioning groove is provided on one side of the housing 21, and the positioning rod 292 is adapted to the positioning groove.

[0039] It should be noted that this achieves the effect of limiting and fixing the housing 21, thereby facilitating the quick disassembly, replacement, and maintenance of the housing 21, and also making it convenient for recycling, thus saving resources.

[0040] like Figures 1-6 As shown, worm gears 34 are rotatably connected inside the two compartments 31 and the two connecting seats 32. First connecting rods 35 are rotatably connected inside the two connecting plates 33 on the left and the two connecting plates 33 on the right. Worm gears 36 are fixedly connected to the middle of the two first connecting rods 35. The outer side of the worm gears 34 meshes with the outer side of the two worm gears 36. First bevel gears 37 are fixedly connected to the front and back of the two first connecting rods 35. Two symmetrically distributed second connecting rods 38 are rotatably connected to the inner walls of the two connecting seats 32 on opposite sides. Second bevel gears 39 are fixedly connected to the outer side of the multiple second connecting rods 38. Third bevel gears 310 are fixedly connected to one end of the multiple second connecting rods 38. Multiple rectangularly distributed lead screws 311 are rotatably connected to the inner top wall of the compartment 31. Fourth bevel gears 312 are fixedly connected to the outer side of the multiple lead screws 311. Bottom plates 313 are threadedly connected to the outer side of the two lead screws 311 on the left and the two lead screws 311 on the right.

[0041] It should be noted that rotating the worm gear 34 causes the two worm wheels 36 to rotate, which in turn causes the two first connecting rods 35 to rotate. The two first connecting rods 35 then cause multiple first bevel gears 37 to rotate, which in turn cause the second bevel gears 39 to rotate. The multiple second bevel gears 39 then cause multiple second connecting rods 38 to rotate, which in turn cause multiple third bevel gears 310 to rotate. The multiple third bevel gears 310 then cause multiple fourth bevel gears 312 to rotate, which in turn cause multiple lead screws 311 to rotate. This causes the two base plates 313 to move downwards, thereby adjusting the height of the bed board 1. This makes it easier for patients to get in and out of bed on their own, reducing the physical exertion required to get up, and is especially suitable for elderly people with limited mobility or patients in the recovery period.

[0042] like Figures 1-6 As shown, the outer side of the bottom plate 313 is slidably connected to the inner wall of the cabin 31.

[0043] It should be noted that this increases the stability of the base plate 313 during movement, and consequently increases the stability of the bed board 1 during height adjustment.

[0044] The working principle of this utility model is as follows: By setting up a telescopic mechanism 2, rotating the rotating rod 26, the rotating rod 26 drives the threaded rod 23 to rotate through the pulley 27 and belt 28. The threaded rod 23 drives the support plate 24 to move forward and extend from the inside of the box 21, making it convenient for the patient to place their feet on the support plate 24, thus facilitating sitting training. By setting up an installation component 29, pulling the positioning rod 292 causes the positioning plate 293 to move to the left, compressing the spring 294. At the same time, the positioning rod 292 is pulled out of the positioning groove on one side of the box 21. Then, the box 21 is pulled forward, causing the T-shaped block 22 to be pulled out from the inside of the T-slot, thus facilitating quick disassembly of the box 21, making it convenient for replacement and maintenance, and also convenient for its reuse. By setting up a lifting mechanism... Structure 3: Rotating the worm gear 34 drives two worm wheels 36 to rotate, which in turn drives two first connecting rods 35 to rotate. The first connecting rods 35 drive multiple first bevel gears 37 to rotate, which in turn drive second bevel gears 39 to rotate. The second bevel gears 39 drive multiple second connecting rods 38 to rotate, which in turn drive multiple third bevel gears 310 to rotate. The third bevel gears 310 drive multiple fourth bevel gears 312 to rotate, which in turn drive multiple lead screws 311 to rotate. This causes the two base plates 313 to move downward, thereby adjusting the height of the bed board 1. This makes it easier for patients to get in and out of bed on their own, reducing the physical exertion required to get up, and is especially suitable for elderly people with limited mobility or patients in the recovery period.
