Utility Model Content

[0005] The purpose of this invention is to provide a wheelchair that can elevate the affected limb, thereby solving the problem that the process of raising the patient's legs is complicated and cumbersome when using the wheelchair, which increases the time and labor intensity of the operation.

[0006] To achieve the aforementioned utility model objective, the present utility model adopts the following technical solution: a wheelchair capable of elevating a limb, comprising two support rods, the two support rods being respectively fixed to the left and right sides of the wheelchair body; a U-shaped seat being detachably provided on the front side of each of the two support rods; two support plates being respectively fixed to the front side of the outer wall of each of the two U-shaped seats; a through hole being provided on one side of each of the two support plates; a leg being rotatably disposed between the two support plates; a leg rest being fixed to the outer wall of each leg; and a pivot being respectively fixed to the left and right sides of each leg; and two pivots being rotatably provided with... The device is placed in the through holes of two support plates. The outer support plate has a fixing groove on its outer side. The outer ends of the two rotating shafts are respectively fixed with baffles. The outer baffles have several fixing holes on their outer sides. An L-shaped frame is fixed to the outer side of the outer support plate. A movable hole is opened on one side of the L-shaped frame. A fixed shaft is slidably inserted into the movable hole. The fixed shaft is slidably inserted into the fixing hole and the fixing groove. A stop block is fixed to the outer end of the fixed shaft. A spring is fixed to the outer side of the L-shaped frame. One end of the spring is fixedly connected to one side of the stop block. The spring is wrapped around the fixed shaft.

[0007] Preferably, a sponge pad is fixed to the front side of each of the two leg supports.

[0008] Preferably, an arc-shaped plate is fixed to the outer wall of each of the two legs, and a foot pedal is fixed to the outer wall of each of the two arc-shaped plates.

[0009] Preferably, threaded grooves are provided on the left and right sides of the two support rods, and threaded holes are provided on the left and right sides of the outer walls of the two U-shaped seats. Bolts are threaded into the two threaded holes, and the threaded ends of the two bolts are threaded into the two threaded grooves.

[0010] Preferably, the inner walls of the two U-shaped seats are respectively fixed with positioning blocks, and the front sides of the two support rods are respectively provided with positioning grooves, and the two positioning grooves respectively position the two positioning blocks.

[0011] Preferably, the outer walls of the two support rods are respectively fixed with rubber pads.

[0012] Compared with existing technologies, a wheelchair that can elevate the affected limb using the above-mentioned technical solution has the following beneficial effects:

[0013] I. In use, when a patient is seated in the wheelchair and needs to elevate their legs to promote blood circulation or relieve discomfort, the operator simply pulls the stop block outwards. This action moves the fixed shaft outwards, disengaging it from the fixed slot. At this point, the spring is stretched. The operator can then rotate the outrigger, causing the rotating shaft to rotate within the through hole of the support plate. This rotation causes the leg rest to rotate as well, until it supports the patient's leg and elevates it to the desired height. Once the desired height is reached, the stop block is released. The spring uses its elastic potential energy to reset the fixed shaft, allowing it to slide back into the fixed slot, thus securing the baffle, outrigger, and leg rest, ensuring stable leg elevation. The combined use of the U-shaped seat, support plate, outrigger, leg rest, baffle, fixed shaft, stop block, and spring facilitates the operator's leg elevation, simplifying the process, improving convenience and safety, and reducing operation time and labor intensity.

[0014] Second, during use, the foam padding provides patients with extra comfort and support, effectively distributing pressure and reducing discomfort caused by prolonged leg elevation. The curved plate, in conjunction with the footrests, allows patients to place both feet on the footrests while raising their legs, maintaining balance and stability, and providing more convenient and comfortable foot support. During use, the use of threaded grooves, threaded holes, and bolts facilitates the disassembly and assembly of the U-shaped seat, making it easy to disassemble and replace other components on the U-shaped seat. This not only improves the flexibility and maintainability of the wheelchair itself but also reduces the cost and time required for replacing parts.

[0015] Thirdly, during use, when installing the U-shaped seat, the operator only needs to align the positioning block with the positioning groove for initial positioning, and then rotate the bolts to fix it. This not only simplifies the installation process but also improves the accuracy and stability of the installation, ensuring the accurate correspondence between the threaded groove and the threaded hole, and avoiding installation failure or component damage due to misalignment. The rubber pad provides a comfortable arm support point for the patient, effectively distributing pressure and reducing discomfort. At the same time, the rubber pad also has anti-slip properties, ensuring that the patient's arm will not slip or lose support when moving or adjusting posture. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a wheelchair capable of elevating a limb includes two support rods 1, which are respectively fixed to the left and right sides of the wheelchair body 2. U-shaped seats 3 are detachably mounted on the front sides of each support rod 1. Two support plates 4 are fixed to the front outer walls of each U-shaped seat 3. Through holes are provided on one side of each support plate 4. A leg 5 is rotatably mounted between the two support plates 4. A leg rest 6 is fixed to the outer wall of each leg 5. Rotating shafts 7 are fixed to the left and right sides of each leg 5. The two rotating shafts 7 are rotatably mounted within the through holes of the two support plates 4. The outer support plate 4... A fixing groove 8 is provided on the side. Baffles 9 are fixed to the outer ends of the two rotating shafts 7 respectively. Several fixing holes 10 are provided on the outer side of the outer baffle 9. An L-shaped frame 11 is fixed to the outer side of the outer support plate 4. A movable hole 12 is provided on one side of the L-shaped frame 11. A fixing shaft 13 is slidably inserted into the movable hole 12. The fixing shaft 13 is slidably inserted into the fixing hole 10 and the fixing groove 8. A stop block 14 is fixed to the outer end of the fixing shaft 13. A spring 15 is fixed to the outer side of the L-shaped frame 11. One end of the spring 15 is fixedly connected to one side of the stop block 14. The spring 15 is wrapped around the fixing shaft 13.

[0023] In use, when the patient is sitting on the wheelchair body 2, if it is necessary to raise the legs to promote blood circulation or relieve discomfort, the staff only needs to pull the stop 14 outward. This action causes the fixed shaft 13 to move outward, thereby disengaging it from the inside of the fixed groove 8. At this time, the spring 15 is in a stretched state. Then, the staff can rotate the outrigger 5, causing the rotating shaft 7 to rotate in the through hole of the support plate 4. This rotation causes the leg support 6 to rotate as well, until it supports the patient's legs and raises them to the required height. When the satisfactory height is reached, the stop 14 is released, and the spring 15 uses its elastic potential energy to reset the fixed shaft 13, allowing it to slide back into the inside of the fixed groove 8, thereby fixing the baffle 9, outrigger 5, and leg support 6, ensuring that the legs are raised stably.

[0024] The U-shaped seat 3, support plate 4, outrigger 5, leg support 6, baffle 9, fixed shaft 13, stop block 14 and spring 15 work together to help staff raise the patient's leg. This not only simplifies the process of raising the affected limb, but also improves the convenience and safety of use, and reduces the time and labor intensity during the operation.

[0025] like Figures 1-3 As shown, sponge pads 16 are fixed to the front sides of the two leg supports 6 respectively.

[0026] During use, the sponge pad 16 provides patients with extra comfort and support, effectively distributing pressure and reducing discomfort caused by raising the legs for extended periods.

[0027] like Figures 1-4 As shown, arc-shaped plates 17 are fixed to the outer walls of the two support legs 5 respectively, and foot pedals 18 are fixed to the outer walls of the two arc-shaped plates 17 respectively. Threaded grooves 19 are opened on the left and right sides of the two support rods 1 respectively. Threaded holes 20 are opened on the left and right sides of the outer walls of the two U-shaped seats 3 respectively. Bolts 21 are threaded into the two threaded holes 20 respectively, and the threaded ends of the two bolts 21 are threaded into the inner threads of the two threaded grooves 19 respectively.

[0028] In use, the coordinated use of the curved plate 17 and the footrest 18 allows the patient to place both feet on the footrest 18 while raising their legs, thus maintaining balance and stability and providing more convenient and comfortable foot support. The use of the threaded groove 19, threaded hole 20, and bolt 21 facilitates the disassembly and assembly of the U-shaped seat 3, making it easier to disassemble and replace other components on the U-shaped seat 3. This not only improves the flexibility and maintainability of the wheelchair body 2 but also reduces the cost and time required for component replacement.

[0029] like Figures 1-4 As shown, positioning blocks 22 are fixed to the inner walls of the two U-shaped seats 3 respectively, and positioning grooves 23 are opened on the front side of the two support rods 1 respectively. The two positioning grooves 23 respectively position the two positioning blocks 22, and rubber pads 24 are fixed to the outer walls of the two support rods 1 respectively.

[0030] During use, when installing the U-shaped base 3, the operator only needs to align the positioning block 22 with the positioning groove 23 for initial positioning, and then rotate the bolt 21 to fix it. This not only simplifies the installation process but also improves the accuracy and stability of the installation, ensuring the accurate correspondence between the threaded groove 19 and the threaded hole 20, and avoiding installation failure or component damage due to misalignment. The rubber pad 24 provides a comfortable arm support point for the patient, effectively distributing pressure and reducing discomfort. At the same time, the rubber pad 24 also has anti-slip properties, ensuring that the patient's arm will not slip or lose support when moving or adjusting posture.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
