A load-bearing rod 2 is hinged to the top of the load-bearing rod 1. A cylinder is hinged to one side of the load-bearing rod 1, and the top of the cylinder is hinged to the bottom of the load-bearing rod 2. A pin is inserted into one end of the load-bearing rod 2. A support mechanism is provided on the outer side of the connecting rod.
[0007] By adopting the above technical solution: using fixed rods and connecting plates to drive the pull rods, and through the opposing deflection of the two bottom rods, different models of wheelchairs can be quickly fitted together, and the two load-bearing rods can be pushed by cylinders to lift the wheelchairs smoothly.
[0008] As a further description of the above technical solution: the support mechanism includes a hook, the inner side of which is engaged with the outer side of a pin, a slot is provided on one side of the hook, a buckle is rotatably connected to the inner side of the hook, a reaction spring is fixedly connected to the inner side of the hook, one side of the reaction spring is engaged with the inner side of the buckle, a bracket is fixedly connected to the bottom of the hook, two load-bearing hooks are fixedly connected to the outer side of the bracket, a fixing plate is fixedly connected to the top of the bottom rod, a protrusion is fixedly connected to one side of the fixing plate, and a rotating plate is rotatably connected to the top of the fixing plate.
[0009] By adopting the above technical solution, the hooks, brackets and load-bearing hooks can be quickly disassembled by the deflection of multiple buckles for installation and replacement, and the bottom of the wheelchair is supported by two rotating plates after being lifted, so that the wheelchair remains stable.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. By setting up a support mechanism, compared with the existing technology, the opposing deflection of two base rods is used to quickly fit different models of wheelchairs, ensuring that the wheelchair and the load-bearing hook quickly approach and remain relatively perpendicular, while reducing the time for manual adjustment of the wheelchair position and reducing the operational complexity for caregivers or users.
[0012] 2. By setting up a support mechanism, compared with the existing technology, the bracket and the second load-bearing rod can be quickly separated by the deflection of the buckle, so as to replace and repair the load-bearing hook. The rotation of the rotating plate can support the two sides of the wheelchair after it is lifted, so as to prevent the wheelchair from tilting or sliding during the lifting process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] The embodiments disclosed in this application are as follows: Figure 1-6 The wheelchair lifting device shown includes a connecting rod 1. Two base rods 2 are rotatably connected to the outer side of the connecting rod 1. One end of each base rod 2 is fixedly connected to a first fixing frame 3, and the other end is fixedly connected to a second fixing frame 4. Both the first fixing frame 3 and the second fixing frame 4 are fixedly connected to the bottom of casters 5. A traction mechanism is provided on one side of the connecting rod 1. The traction mechanism includes a fixed shaft 6, one side of which is fixedly connected to the outer side of the connecting rod 1. A connecting plate 7 is rotatably connected to the outer side of the fixed shaft 6. A fixing rod 8 is fixedly connected to the top of the connecting plate 7. Two pedals 9 are fixedly connected to the top of the fixing rod 8. Two fixing pins 10 are rotatably connected to the outer side of the connecting plate 7. A pull rod 11 is fixedly connected, and a fixing pin 12 is hinged to the outside of the pull rod 11. One end of the fixing pin 12 is rotatably connected to the outside of the base rod 2. A load-bearing rod 13 is fixedly connected to the top of the connecting rod 1. A load-bearing rod 14 is hinged to the top of the load-bearing rod 13. A cylinder 15 is hinged to one side of the load-bearing rod 13. The top of the cylinder 15 is hinged to the bottom of the load-bearing rod 14. A pin 16 is inserted into one end of the load-bearing rod 14. A support mechanism is set on the outside of the connecting rod 1. The two pull rods 11 and the fixing pin 12 are driven by the pedal 9, the fixing rod 8, and the connecting plate 7 to transmit power to the base rod 2, so that the two base rods 2 can be expanded by the connecting rod 1 to fit different models of wheelchairs.
[0022] Reference Figure 3 , Figure 5 and Figure 6As shown, the support mechanism includes a hook 17, the inner side of which engages with the outer side of the pin 16. A slot 18 is provided on one side of the hook 17. A buckle 19 is rotatably connected to the inner side of the hook 17. A reaction spring 20 is fixedly connected to the inner side of the hook 17. One side of the reaction spring 20 engages with the inner side of the buckle 19. A bracket 21 is fixedly connected to the bottom of the hook 17. Two load-bearing hooks 22 are fixedly connected to the outer side of the bracket 21. A fixing plate 23 is fixedly connected to the top of the bottom rod 2. A protrusion 24 is fixedly connected to one side of the fixing plate 23. A rotating plate 25 is rotatably connected to the top of the fixing plate 23. Pressing the buckle 19 can quickly disassemble and separate the hook 17 and the load-bearing rod 24. The rotating plate 25 is used to support the bottom of the wheelchair after it is lifted, so that the wheelchair remains stable during the lifting and transportation process.
[0023] The working principle of this utility model is as follows: When assisting in the transfer of a patient's wheelchair, the staff first steps on one of the pedals 9, which causes the fixing rod 8 and the connecting plate 7 to deflect on the outside of the fixing shaft 6. The connecting plate 7 then drives one end of the two pull rods 11 to pull to the opposite side, causing the other end of the two pull rods 11 to drive the corresponding fixing pin 12 and the two bottom rods 2 to deflect. The two bottom rods 2 then deflect at both ends of the connecting rod 1. The wheelchair is then pushed between the two bottom rods 2. The load-bearing hooks 22 on both sides of the wheelchair and the support 21 are then fixed by the external suspension rope. Then, the cylinder 15 is activated to push the load-bearing rod 14 to deflect at the top of the load-bearing rod 13, causing the load-bearing rod 14 to drive the hook 17, the support 21 and the load-bearing hook 22 to lift the wheelchair. Then, the two rotating plates 25 are deflected towards the side where the wheelchair is lifted, so that the two rotating plates 25 support and limit the bottom of the wheelchair. Finally, pushing the load-bearing rod 13 allows the lifting device to move smoothly under the rolling of multiple casters 5.
[0024] When the load-bearing hook 22 deforms during use, the buckle 19 is pressed to deflect inside the hook 17 and to squeeze and push the reaction spring 20, so that one end of the buckle 19 enters the inside of the hook 17, so as to separate the slot 18 on one side of the hook 17 from the pin 16, thereby separating the hook 17 and the bracket 21 from the load-bearing rod 14, making it easier to disassemble and repair the load-bearing hook 22.
