[0017] like Figures 1-10 As shown, it includes a horizontal plate 1, with support plates 11 fixed to both ends of the horizontal plate 1. Handrails 12 are fixed to one side of the top of the two support plates 11. Two sets of limiting grooves 13 are provided on the side of the horizontal plate 1 away from the handrails 12. A quick-release assembly is provided in the middle of the horizontal plate 1, and an adjustment assembly is provided in the middle of the support plates 11.

[0018] The quick-release assembly includes two sets of fixing plates 2, a protective box 21, two sets of limiting slide plates 22, two sets of support blocks 23, and a dual-axis motor 24. The two fixing plates 2 are respectively fixed to the two sides of the horizontal plate 1 away from the handrail 12. The protective box 21 is fixed to the side of the horizontal plate 1 away from the handrail 12. The two limiting slide plates 22 are respectively slidably connected to the middle of the two sets of limiting grooves 13. The two support blocks 23 are respectively fixed to the two sides of the horizontal plate 1 away from the handrail 12. The dual-axis motor 24 is installed in the middle of the protective box 21.

[0019] The quick-release assembly also includes multiple sets of ventilation holes 3, a rotating shaft 31, two sets of first lead screws 32, and two sets of movable clamping plates 33. The ventilation holes 3 are all located on the side of the protective box 21 away from the horizontal plate 1. One end of the rotating shaft 31 is fixed to the output end of the dual-axis motor 24 near the fixed clamping plate 2, and the other end of the rotating shaft 31 is rotatably connected to the side of a set of support plates 11 away from the protective box 21. The tops of the two first lead screws 32 are rotatably connected to the middle of the two sets of fixed clamping plates 2, and the bottoms of the two first lead screws 32 are rotatably connected to the middle of the two sets of support blocks 23. The two movable clamping plates 33 are fixed to one end of the two sets of limiting slide plates 22, and the middle parts of the two sets of movable clamping plates 33 are threaded to the middle of the two sets of first lead screws 32.

[0020] The quick-release assembly also includes two sets of first worm gears 4 and two sets of first worms 41. The two first worm gears 4 are respectively fixed to the bottom of the two sets of first lead screws 32, and the two first worms 41 are both fixed to the middle of the rotating shaft 31. The two sets of first worm gears 4 mesh with the two sets of first worms 41 respectively.

[0021] When it is necessary to install anti-fall handrails on the hospital bed during operation, the fixed clamp 2 can be clamped above the side of the hospital bed, and then the dual-axis motor 24 is driven to rotate the output end of the rotating shaft 31. When the rotating shaft 31 rotates, it will synchronously drive the first worm gear 41 to rotate. Under the rotation of the first worm gear 41, the first worm wheel 4 will be driven to rotate, which in turn drives the first lead screw 32 to rotate at the fixed clamp 2 and the support block 23. When the first lead screw 32 rotates, it will drive the limiting slide plate 22 and the movable clamp 33 to move. At this time, the movement of the limiting slide plate 22 is restricted by the limiting groove 13, so that the limiting slide plate 22 drives the movable clamp 33 to slide upward in a straight line at the middle of the first lead screw 32 until the movable clamp 33 is moved to the bottom of the side of the hospital bed, and then the dual-axis motor 24 can be stopped. In this way, the horizontal plate 1, the support plate 11 and the handrail 12 can be installed at the hospital bed in conjunction with the fixed clamp 2. When the patient needs to get out of bed, he / she can hold the handrail 12 to get out of bed.

[0022] The support block 23 supports the first lead screw 32, thereby improving its stability during rotation. The protective box 21 protects the dual-axis motor 24, reducing the risk of damage caused by collisions with the hospital bed during disassembly due to exposure to the external environment. The ventilation hole 3 allows air to circulate between the protective box 21 and the outside, thus aiding in heat dissipation of the dual-axis motor 24.

[0023] This step, through the setting of quick-release components, transforms the fixed anti-fall handrail into a detachable one, thereby improving its flexibility in use. It facilitates regular deep cleaning and disinfection to ensure hygiene and safety, and allows for quick relocation of the installation position according to actual needs, even enabling sharing across wards. This optimizes the patient care experience, effectively reduces hospital equipment management costs, improves the turnover efficiency of medical resources, and allows for rapid adjustment of ward layout to cope with sudden medical needs.

[0024] The adjustment assembly includes two sets of rectangular slides 5, guide rods 51, and a second lead screw 52. The two rectangular slides 5 are respectively opened in the middle of the two sets of support plates 11 on the side close to each other. The two ends of the guide rods 51 are respectively fixed to the upper and lower ends of the support plate 11 away from the protective box 21. The two ends of the second lead screw 52 are respectively rotatably connected to the upper and lower ends of the support plate 11 near the protective box 21.

[0025] The adjustment assembly also includes a second worm gear 6 and a second worm 61. The second worm gear 6 is fixed to the top of the second lead screw 52. One end of the second worm 61 is fixed to the output end of the dual-axis motor 24 away from the fixed clamping plate 2. The other end of the second worm 61 is rotatably connected to the inner side wall of the support plate 11, and the second worm 61 and the second worm gear 6 mesh with each other.

[0026] The adjustment assembly also includes a threaded slider 7, a guide slider 71, and a pedal 72. The threaded slider 7 is threadedly connected to the middle of the second lead screw 52, ​​the guide slider 71 is slidably connected to the middle of the guide rod 51, and the two ends of the pedal 72 are respectively fixed to the guide slider 71 and the threaded slider 7 on the side that are close to each other.

[0027] During operation, when the position of the pedal 72 needs to be adjusted according to the patient's height, the output end of the dual-axis motor 24, which is equipped with the second worm gear 61, can rotate. The rotation of the second worm gear 61 can drive the second worm wheel 6 to rotate, thereby driving the second lead screw 52 to rotate. The rotation of the second lead screw 52 will drive the threaded slider 7 to move. When the threaded slider 7 moves, it will also drive the pedal 72 and the guide slider 71 to move synchronously. Through the interaction of the pedal 72, the pedal 72 and the guide rod 51, the movement trajectory of the threaded slider 7 can be changed, so that it slides up and down in a straight line in the middle of the second lead screw 52, ​​thereby adjusting the height of the pedal 72.

[0028] This step allows for flexible adjustment of the height of the footrest 72 based on the patient's height, enabling the patient's feet to be placed naturally and comfortably on the footrest 72. This reduces undesirable postures such as feet dangling, excessive knee bending, or forward leaning caused by an unsuitable footrest height, effectively alleviating muscle fatigue in the patient's lower limbs, improving their balance and stability while standing, and significantly reducing the risk of falls due to improper posture or physical exhaustion, thus providing a more reliable guarantee for the patient's safety.

[0029] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
