[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] Combination Figure 1-Figure 6 A supporting wheelchair for elderly patients includes a seat cushion 13, and cross beams 12 are fixedly connected on both sides of the seat cushion 13. A vertical pushing handle 11 is fixedly arranged at one end of the cross beam 12 close to the backrest, and a supporting mechanism 2 is arranged on the lower side of the two cross beams 12 and between the two pushing handles 11.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Between the two pushing and supporting handles 11, a rear connecting column 14 is fixedly connected to one end close to the backrest, and a front connecting column 15 is fixedly connected to the other end. The rear connecting column 14 and the pushing and supporting handles 11 are in the same plane;

[0029] The supporting mechanism 2 includes a backrest rod 21 rotatably mounted on the surface of the rear connecting column 14 near the lower end, and a support rod 23 rotatably mounted on the surface of the front connecting column 15 at the upper end. A linkage rod 22 is rotatably connected between the lower end of the backrest rod 21 and the surface of the support rod 23. The rotatable connection among the crossbeam rod 12, the backrest rod 21, the linkage rod 22 and the support rod 23 constructs a quadrilateral in a side view. Two backrest rods 21 and two support rods 23 are provided, which are respectively located at the two ends of the rear connecting column 14 and the front connecting column 15. A backrest plate 26 is fixedly provided between the two backrest rods 21 and above the rear connecting column 14. A support belt 24 is provided between the two support rods 23. A fastening component 3 for fixing the position of the backrest rod 21 is provided on the side surface of the push handle rod 11.

[0030] The above-mentioned working principle and technical effect are as follows: under normal conditions, the two backrest rods 21 and the two push handle rods 11 are on the same plane, and the support rod 23 also hangs down below the front connecting column 15. The fastening assembly 3 fixes the position of the backrest rod 21. Indirectly, the position of the backrest rod 21 is fixed through the linkage rod 22, which also plays a role in fixing the position of the support rod 23, thereby meeting the normal daily use of the wheelchair. When it is necessary to relieve edema of the patient's lower limbs, by rotating the backrest rod 21 backward, the lower end of the backrest rod 21 will push the support rod 23 outward through the linkage rod 22, so that the support belt 24 between the two support rods 23 lifts the patient's legs, which has the effect of relieving pressure on the lower limbs and preventing lower limb edema. After the backrest rod 21 is rotated backward, the backrest plate 26 arranged on the backrest rod 21 is in an inclined state, which is convenient for the patient to lean his back on the surface of the backrest plate 26, so as to relieve the pressure on the patient's sacrum and coccyx, and avoid pressure sores caused by overpressure.

[0031] In the previous embodiment: on the surface of the rear connecting column 14, the distance length between the rotational connection position of the backrest rod 21 and the dynamic connection position of the linkage rod 22 is recorded as the swing arm A211; on the surface of the support rod 23, the distance length between the rotational connection position of the front connecting column 15 and the dynamic connection position of the linkage rod 22 is recorded as the swing arm B231; the length of the swing arm A211 is greater than the length of the swing arm B231.

[0032] The above working principle and technical effect are as follows: by setting the length of the swing arm A211 to be greater than that of the swing arm B231, the swing range of the lower end of the swing arm A211 around the rear connecting column 14 will be greater than the swing range of the lower end of the swing arm B231 around the front connecting column 15. This will cause the linkage rod 22 to push the support rod 23 to rotate around the front connecting column 15 at a larger angle during the process of rotating the backrest rod 21 to reach a fixed angle, thereby prompting the backrest rod 21 to rotate to a fixed angle, thereby satisfying the patient's side-lying comfort and allowing the support rod 23 to be propped outward to a specified height to lift the lower limbs to a corresponding height, thereby meeting the height requirement for relieving lower limb pressure.

[0033] In the previous embodiment: the support rod 23 is configured as an obtuse-angled folding frame, the linkage rod 22 is rotatably connected to the bent portion of the support rod 23 , and the obtuse angle of the support rod 23 is located on the side away from the linkage rod 22 .

[0034] The above working principle and technical effect are: by setting the support rod 23 as a folding frame, when the support rod 23 is stretched out, the area of ​​the support rod 23 with the support belt 24 can be more horizontal, which is convenient for further lifting the patient's lower limbs. When the support rod 23 is stored to the lower side of the cross beam 12, the part of the support rod 23 with the support belt 24 can be stored inwardly under the cross beam 12 to avoid affecting the normal use of the wheelchair.

[0035] In the previous embodiment: a telescopic rod 221 is provided in the middle of the linkage rod 22 , and the telescopic rod 221 is used to adjust the length of the linkage rod 22 .

[0036] The above working principle and technical effect are: by adjusting the length of the linkage rod 22 by adjusting the telescopic rod 221, it is convenient to adjust the coordination effect of the inclination degree of the backrest rod 21 and the extension degree of the support rod 23, so as to adjust the angle corresponding to the inclination of the backrest rod 21 when the support rod 23 is extended to the standard height, thereby adjusting the degree of the patient's side lying.

[0037] In the previous embodiment: two soft support pads 25 are provided on the upper surfaces of the plurality of support straps 24, and the soft support pads 25 are arranged on the upper surfaces of the support straps 24 in accordance with the direction in which the lower limbs are placed. The upper surface of the support straps 24 is also provided with a concave prevention groove.

[0038] The above working principle and technical effect are: by setting the soft support pad 25, the contact area with the lower limbs is increased, the pressure on the skin surface of the lower limbs is further reduced, and the occurrence of pressure sores is avoided.

[0039] Furthermore, the upper surface of the cushion 13 and the surface of the backboard 26 close to the cushion 13 are provided with soft materials, which are used to increase the contact area with the corresponding skin, further reduce the pressure on the skin in the corresponding area, and avoid the occurrence of pressure sores.

[0040] In the previous embodiment: the fastening assembly 3 includes an arc-shaped guide rail 31 fixedly arranged on the side surface of the push handle rod 11, and a threaded column 32 fixedly arranged on the side surface of the backrest rod 21, the threaded column 32 passes through the inner side of the arc-shaped guide rail 31, and its outer end is threadedly connected with a fastening nut 33.

[0041] The above working principle and technical effect are as follows: when adjusting the angle of the backrest rod 21, the threaded column 32 will also move in the arc guide rail 31. After the backrest rod 21 is pushed to a predetermined angle, the fastening nut 33 is rotated so that the fastening nut 33 rubs against the surface of one side of the arc guide rail 31, thereby fixing the angle of the backrest rod 21 on one side of the push handle 11.

[0042] In the previous embodiment: a drip stand 4 is also provided on one side of the push handle 11, and the drip stand 4 is used for hanging the drip bottle.
