When the support block 59 descends, it will drive the fixing component 1 58 to slide out from the inside of the square hole 1 52 and get stuck in the inside of the square hole 2 53, so that the support block 59 contacts the ground, thereby increasing the contact area between the device and the ground, so as to improve the stability of the device when transporting patients.

[0045] Furthermore, the universal wheel limiting mechanism 5 of the present invention further comprises a limiting groove 55 and a limiting block 57. The limiting block 57 is arranged on the side of the support block 59, and the inner wall of the mounting seat 54 is provided with a limiting groove 55 corresponding to the limiting block 57.

[0046] By adopting the above technical solution, when the support block 59 is lifted or lowered, the limiting block 57 is driven to slide inside the limiting groove 55, thereby improving the stability of the lifting process of the support block 59.

[0047] Further, the present invention, the fixing assembly 58 includes an arc structure 581, a block 582, a limit plate 583 and a spring 584.

When the clamping block 582 is aligned with the square hole 2 53, the spring 1 584 rebounds, thereby driving the clamping block 582 to be clamped into the interior of the square hole 2 53, so as to fix the support block 59.

[0049] When the present embodiment is in use, after the device is driven to move to a suitable position by the universal wheel body 6, the pedal 51 is stepped on by the foot to drive the support block 59 to descend. When the support block 59 descends, the fixing assembly 1 58 is driven to slide out from the inside of the square hole 1 52 and be stuck in the inside of the square hole 2 53, so that the support block 59 contacts the ground, thereby increasing the contact area between the device and the ground, so as to improve the stability of the device in carrying patients. When the support block 59 is raised or lowered, the limiting block 57 is driven to slide in the inside of the limiting groove 55, so as to improve the stability of the support block 59 during the lifting process. When the support block 59 slides downward, the arc structure 581 on the lower end surface of the square hole 1 52 and the blocking block 582 is driven to compress the limiting plate 1 583 and the spring 1 584 and embed into the inside of the support block 59.

At this time, the guardrail body 22 is driven to rotate to a direction perpendicular to the bed board 3 through the rotating shaft 23, and the handle 245 is released, and the spring 243 rebounds, thereby driving the fixing rod 242 to be inserted into the fixing hole 21 to achieve the fixation of the guardrail body 22.

[0055] When the present embodiment is in use, when fixing the guardrail body 22, the handle 245 is pulled, the handle 245 pulls the pull rod 244, the pull rod 244 pulls the limit plate 241 and the fixing rod 242, and drives the spring 243 to be compressed. At this time, the guardrail body 22 is driven to rotate to a direction perpendicular to the bed board 3 through the rotating shaft 23, the handle 245 is released, the spring 243 rebounds, thereby driving the fixing rod 242 to be inserted into the fixing hole 21, so as to fix the guardrail body 22, so as to avoid contact between the patient and the medical staff during the transfer, thereby causing the medical staff to be infected. At the same time, after the guardrail is fixed, the medical staff also need to wear N95 masks to avoid infection problems.

[0056] Working principle and use process of the present invention: When the present invention is in use, when the height of the bed board 3 is adjusted, the motor 77 on the side of the second mounting plate 76 is turned on, and the motor 77 drives the two-way screw rod 1 74 to rotate through the output end, and the two-way screw rod 1 74 rotates to drive the two sets of slides 73 to move closer to or away from each other, and the two-way screw rod 1 74 rotates to drive the gear 1 722 to rotate, and the gear 1 722 rotates to drive the flexible toothed belt 721 to rotate, and the flexible toothed belt 721 rotates to drive the gear 2 724 to rotate, and the gear 2 724 rotates to drive the two-way screw rod 2 723 to rotate, thereby driving the other two sets of slides 73 to move closer to or away from each other, and the slide 73 slides to drive The hinge seats 1 75 move closer to or farther from each other. When the hinge seats 1 75 move closer to or farther from each other, they will cooperate with the hinge seat 2 79 to drive the angle of the support plate 78 to be adjusted, thereby realizing the height adjustment of the bed board 3. When the bed board 3 is raised or lowered, the inner rod 710 will be driven to slide inside the outer rod 711, thereby improving the stability of the bed board 3 during the lifting process. After the device is moved to a suitable position by the universal wheel body 6, the pedal 51 is stepped on with the foot to drive the support block 59 to descend. When the support block 59 descends, it will drive the fixing assembly 1 58 to slide out from the inside of the square hole 1 52 and get stuck in the inside of the square hole 2 53, so that the support block 59 is in contact with the ground. When the support block 59 is lifted or lowered, the limit block 57 is driven to slide inside the limit groove 55, thereby improving the stability of the support block 59 during the lifting or lowering process. When the support block 59 slides downward, the arc structure 581 on the lower end surface of the square hole 1 52 and the block 582 is driven to compress the limit plate 1 583 and the spring 1 584 and embed them into the inside of the support block 59. When the block 582 is aligned with the square hole 2 53, the spring 1 584 rebounds, thereby driving the block 582 to be stuck into the inside of the square hole 2 53 to fix the support block 59. When the guardrail body 22 is fixed, pull the handle 245, the handle 245 pulls the pull rod 244, the pull rod 244 pulls the limit plate 241 and the fixing rod 242, and drives the spring 243 to compress. At this time, the guardrail body 22 is driven to rotate to a direction perpendicular to the bed board 3 through the rotating shaft 23, release the handle 245, and the spring 243 rebounds, thereby driving the fixing rod 242 to insert into the fixing hole 21 to achieve the fixation of the guardrail body 22, so as to avoid contact between the patient and the medical staff during the transfer, thereby causing the medical staff to be infected. At the same time, after the guardrail is fixed, the medical staff also need to wear N95 masks to avoid infection problems.
