[0031] refer to Figure 1 The present application provides a non-magnetic wheelchair, which includes a seat plate 1, a wheelchair frame 2, a support plate 3 and a wheel assembly. The seat plate 1 is arranged in the wheelchair frame 2; a first sliding groove 11 is opened at the bottom of the seat plate 1, and the support plate 3 is arranged in the first sliding groove 11. The support plate 3 can slide back and forth along the first sliding groove 11 to realize the extension or storage of the support plate 3 relative to the seat plate 1; the wheel assembly is arranged at the bottom of the wheelchair frame 2, and the wheel assembly is used to drive the non-magnetic wheelchair to move.

[0032] The present application provides a non-magnetic wheelchair, by opening a first sliding groove 11 at the bottom end of the seat plate 1, the support plate 3 is arranged in the first sliding groove 11, and the support plate 3 can slide back and forth along the first sliding groove 11, so as to realize the extension or storage of the support plate 3 relative to the seat plate 1. When the patient needs to sit on the non-magnetic wheelchair, the support plate 3 slides inwards, and the support plate 3 is stored in the seat plate 1, which is convenient for the patient to sit on the non-magnetic wheelchair. After the patient sits on the non-magnetic wheelchair, the support plate 3 slides outwards, and the support plate 3 extends out. The extended support plate 3 can support the patient's lower limbs. Therefore, the non-magnetic wheelchair of the present application has the function of supporting the patient's lower limbs. For patients with orthopedic lower limb diseases, the support plate 3 can be placed by patients with orthopedic lower limb needs, thereby providing safer transportation for patients with orthopedic lower limb diseases.

[0033] Specifically, in the prior art, patients with lower limb injuries, especially those who have undergone orthopedic lower limb surgery, are required to use wheelchairs with lower limb support functions during the transfer process, and most patients need to undergo postoperative MRI (Magnetic Resonance Imaging) review. If they want to enter the MRI scan, they must change to a non-magnetic wheelchair for transfer. However, none of the non-magnetic wheelchairs currently on the market have the function of supporting the lower limbs. Since the non-magnetic bed is relatively high in height, and the patient already has diseases in the lower limbs, it is difficult to get on and off the bed, which is even more inconvenient. Therefore, it is often necessary for 1 to 2 medical staff to help the patient enter the MRI room on one foot. The process is slow and there are risks. The non-magnetic wheelchair of this application solves the above problems very well. The patient only needs to stand up in the preparation area and change to our non-magnetic wheelchair, and then he can be directly transferred into the MRI room without moving a step. At the same time, the non-magnetic wheelchair also has the lower limb support function that an orthopedic wheelchair should have. When the patient arrives at the MRI bedside, the doctor can come to help the patient get on the bed. The entire process only requires one medical staff, which is safe and efficient.

[0034] Specifically, the non-magnetic wheelchair of the present application is made of non-magnetic materials. The seat plate 1, the wheelchair frame 2 and the support plate 3 are made of wooden materials. Wood is an environmentally friendly renewable resource. Compared with the prior art that uses one-piece molded plastic modules or uses non-magnetic alloys to make non-magnetic wheelchairs, the production cost is high and the price is expensive. One-piece molding also leads to expensive replacement of parts. The non-magnetic wheelchair of the present application is formed by a combination of wood with mortise and tenon structures and glue, which will not pollute the environment, is cheap, and easy to replace parts.

[0035] Specifically, the top of the support plate 3 is slightly lower than the top of the seat plate 1, which is convenient for the patient to place the raised lower limbs.

[0036] refer to Figure 1 The support plate 3 includes a main body 31 and a limiting portion 32 . The main body 31 is disposed in the first sliding groove 11 . The limiting portion 32 is disposed at at least one end of the main body 31 . The limiting portion 32 is disposed outside the first sliding groove 11 .

[0037] refer to Figure 1 The bottom of the seat plate 1 is provided with two first sliding grooves 11 at intervals, and the number of the supporting plates 3 is two, and the two supporting plates 3 are respectively arranged in the two first sliding grooves 11. The two supporting plates 3 arranged at intervals can meet the needs of different patients and facilitate supporting the left lower limb or the right lower limb or both lower limbs of the patient.

[0038] In this embodiment, the first sliding groove 11 is formed by a groove at the bottom of the seat plate 1, and the first sliding groove is set along the axial direction of the seat plate 1. In other embodiments, the seat plate 1 is formed by two plates bonded together with glue, at least one of the plates has a groove, and the two plates are bonded to form the axially penetrating first sliding groove 11.

[0039] refer to Figure 1 The wheelchair frame 2 includes a side panel 21 and a back panel 22 . There are two side panels 21 . The two side panels 21 are arranged on opposite sides of the seat panel 1 . The back panel 22 is arranged between the two side panels 21 , and the back panel 22 is connected to the seat panel 1 .

[0040] Specifically, the two side panels 21 are arranged relatively parallel, the seat panel 1 is arranged in the middle of the two side panels 21, the two ends of the back panel 22 are respectively connected to the same end of the two side panels 21, the side panels 21, the seat panel 1 and the back panel 22 are perpendicular to each other, and form a space for accommodating patients above the seat panel 1.

[0041] Specifically, the seat plate 1 , the side plates 21 and the back plate 22 are all in plate shape.

[0042] In this embodiment, the seat plate 1 is horizontally arranged, the two side plates 21 are vertically arranged along the length direction of the seat plate 1 , and the back plate 22 is vertically arranged along the width direction of the seat plate 1 .

[0043] Furthermore, the side plate 21 is also provided with through holes 23 to promote air circulation and help heat dissipation.

[0044] Specifically, the axial direction of the first sliding groove 11 is parallel to the length direction of the seat plate 1 .

[0045] In this embodiment, the limiting portion 32 includes a first limiting member 33, which is arranged at one end of the main body 31 away from the back plate 22. The first limiting member 33 is used to limit the movement range of the main body 31 toward the direction close to the back plate 22 to prevent the support plate 3 from disengaging from the first sliding groove 11.

[0046] Specifically, the first limiting member is approximately cylindrical.

[0047] Specifically, the thickness of the first limiting member 33 is greater than the height of the first sliding groove 11 , and the thickness of the main body 31 is less than the height of the first sliding groove 11 , so that the main body 31 can slide in the first sliding groove 11 .

[0048] Specifically, refer to Figure 3The limiting portion 32 also includes a second limiting member 34, and the second limiting member 34 and the first limiting member 33 are arranged opposite to each other. The second limiting member 34 is arranged at one end of the main body 31 close to the back plate 22, and the second limiting member 34 is arranged on the side wall of the main body 31, so that the width of the main body 31 and the second limiting member 34 is greater than the width of the first sliding groove 11, thereby limiting the moving range of the main body 31 in the direction away from the back plate 22. The second limiting member 34 cooperates with the first limiting member 33 to limit the moving range of the front and rear sides of the main body 31, further preventing the support plate 3 from disengaging from the first sliding groove 11.

[0049] The first limiting member 33 and the main body 31 are integrally formed, and the first limiting member 33 and the main body 31 are assembled into the first sliding groove 11. After the assembly is completed, the second limiting member 34 is set at the end of the main body away from the first limiting member 33 by gluing, thereby completing the assembly of the support plate 3.

[0050] refer to Figure 1 The wheelchair frame 2 also includes a push handle 24, which is disposed at the top of the backboard 22. The push handle 24 is provided to facilitate the user to hold the push handle 24 to push the non-magnetic wheelchair to move.

[0051] Specifically, there are two push handles 24, which are respectively arranged at the two ends of the back plate 22, so as to facilitate the user to hold with both hands. In this embodiment, the axial direction of the push handle 24 is parallel to the length direction of the seat plate 1.

[0052] refer to Figure 1 The non-magnetic wheelchair also includes a foot pedal 4, which is arranged between the two side panels 21, and the foot pedal 4 is located below the support plate 3 for the patient's feet to be placed.

[0053] refer to Figure 1 A second sliding groove 211 is respectively opened on the inner side of the two side panels 21. The two second sliding grooves 211 are relatively arranged below the support plate 3. Both sides of the foot pedal 4 are respectively arranged in the second sliding grooves 211. The foot pedal 4 can move back and forth along the second sliding grooves 211 to realize the extension or contraction of the foot pedal 4 relative to the wheelchair frame 2.

[0054] Specifically, by providing a foot pedal 4, the patient's feet can be supported when the patient is in a normal posture, thereby improving the comfort of sitting in the wheelchair. When the non-magnetic wheelchair is not in use, the foot pedal 4 can be retracted and recovered, which helps to save storage space and facilitates transportation and storage.

[0055] refer to Figure 1 The wheelchair frame 2 further includes an armrest 25, which is disposed at the top of the side panel 21. In the present embodiment, each of the two side panels 21 has an armrest 25, and specifically, the armrest 25 is also made of wooden material.

[0056] refer to Figure 1 and Figure 2 The wheel assembly includes a front wheel assembly 5 and a rear wheel assembly 6. The front wheel assembly 5 and the rear wheel assembly 6 are both arranged at the bottom of the wheelchair frame 2, and the front wheel assembly 5 and the rear wheel assembly 6 are arranged opposite to each other.

[0057] Specifically, the front wheel assembly 5 includes two front wheels 51, which are arranged at opposite sides of the front end of the wheelchair frame 2, specifically, one front wheel 51 is arranged at the bottom end of one side plate 21, and the other front wheel 51 is arranged at the bottom end of the other side plate 21. Further, the front wheel 51 is a medical non-magnetic universal wheel, and one front wheel 51 can bear a load of 50 kg.

[0058] The rear wheel assembly 6 includes two rear wheels 61 and a drive shaft 62. The two rear wheels 61 are arranged on opposite sides of the rear end of the wheelchair frame 2.

The two rear wheels 61 are connected by a shaft 62. Furthermore, the drive shaft 62 passes through the two side panels 21 and is respectively connected to the center of the two rear wheels 61. The drive shaft 62 is a solid wooden column. The rear wheels 61 are made of three layers of wooden wheels with increasing diameters from the inside to the outside, and the outer periphery of the outer wooden wheel is covered with a solid tire of the same size to protect the wooden wheel.

[0059] Furthermore, the diameter of the front wheel 51 is smaller than the diameter of the rear wheel 61, which can enhance the flexibility, maneuverability and comfort of the wheelchair. Since the front wheel 51 is smaller, the turning radius of the non-magnetic wheelchair is smaller, and it can be more flexibly operated in a small space, and the larger rear wheel 61 can provide better stability and support.

[0060] refer to Figure 3 The wheel assembly also includes a brake assembly 7, which is configured to abut or separate from the rear wheel assembly 6 to achieve braking or release of the wheel assembly.

[0061] Specifically, refer to Figures 3 to 5 The brake assembly 7 includes a bolt 71. A slot 72 is provided on the side of the back plate 22 away from the seat plate 1.

The outer wall of the slot 72 is also provided with a locking hole 73. The supporting portion 712 passes through the locking hole 73 and extends to the outside of the slot 72 for the user to hold.

[0065] Specifically, the locking opening 73 includes a first opening 731, a second opening 732 and a third opening 733 that are connected to each other. The second opening 732 is arranged between the third opening 733 and the first opening 731, and the second opening 732 is connected to the top of the third opening 733 and the first opening 731 respectively. The width of the second opening 732 is smaller than that of the first opening 731 and the third opening 733. The first opening 731, the second opening 732 and the third opening 733 form a "concave" shape. A through opening 731 is located on one side close to the inner side of the rear wheel 61. When the supporting portion 712 moves into the first through opening 731, the end of the connecting portion 711 away from the supporting portion 712 is inserted into the groove 63 of the rear wheel 61, and the rear wheel 61 is braked. When the supporting portion 712 moves from the first through opening 731 and moves to the third through opening 733 through the second through opening 732, the end of the connecting portion 711 away from the supporting portion 712 is separated from the groove 63, and the rear wheel 61 is released, so that it can be pushed to drive the non-magnetic wheelchair to move.

[0066] Furthermore, the length of the second opening 732 is greater than the depth of the groove 63 , so that when the connecting portion 711 moves into the third opening 733 , the connecting portion 711 can be completely separated from the groove 63 .

[0067] In this embodiment, the first opening 731 and the third opening 733 have the same shape and size. The length of the first opening 731 is slightly larger than the diameter of the abutting portion 712.

[0068] In this embodiment, there are two brake assemblies 7, one of which is configured to abut against or separate from one of the rear wheels 61, and the other brake assembly 7 is configured to abut against or separate from the other rear wheel 61, so as to further improve the braking effect.
