For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example, see Figures 1 to 8, an adjustable combined wheelchair that is convenient for nursing operation, comprising two wheelchair bodies arranged in pairs, the wheelchair body consisting of two semi-folding wheelchair bodies arranged opposite to each other, which are convenient for folding and storage, the semi-folding wheelchair bodies are connected by an upper control linkage and a lower fixed support, and the upper control linkage is used to control the operation of the wheelchair in different states;

[0033] Furthermore, a connecting seat 8 is fixedly connected to the side wall of the semi-foldable wheelchair body, and the control linkage member includes a control link plate 10 rotatably connected to the connecting seat 8 on one side through a fixed shaft 9, and the other end of the control link plate 10 is connected to the connecting seat 8 on the other side through a spacing-adjustable locking member;

[0034] Push handles 11 are provided at both ends of the control link plate 10 . The push handle 11 on one side is fixedly provided on the control link plate 10 , and the push handle 11 on the other side is connected to the control link plate 10 through an adjustment control member.

[0035] Furthermore, the adjustable spacing locking member includes an arc-shaped opening 12 provided on the control link plate 10, a lateral movement opening is provided at the arc-shaped opening 12, reinforcement strips 13 for increasing friction are provided on both sides of the lateral movement opening, and a fastening locking knob 14 is connected to the side wall of the connecting seat 8 through a threaded column;

[0036] The tightening and locking knob 14 can achieve the effect of improving the tightening force through the reinforcing strip 13 with large friction force.

[0037] The advantage of adopting the above structure is that when the wheelchair is unfolded for use, the control link plate 10 can be rotated with the fixed shaft 9 as the axis so that the arc-shaped opening 12 provided on the control link plate 10 corresponds to the threaded column. At this time, according to different states, the distance between the semi-folded wheelchair bodies can be changed to achieve the effect of controlling the width of the wheelchair. The lateral movement opening provided thereon can realize the lateral movement of the threaded column therein during the process of adjusting the width of the wheelchair, and the locking and fixing effect at different widths can be achieved by tightening the locking knob 14.

[0039] It should be noted that the traction control plate 17 will gradually be pulled into a tilted state when the two pushing handles 11 are brought closer together. In this state, when the steering of the two combined wheelchairs needs to be adjusted, the two pushing handles 11 can be squeezed, and the pushing handles 11 slidably connected by the sliding member will move. During the movement, a pulling force will be applied to the traction control plate 17, thereby controlling one side of the wheelchair to be pulled inward, thereby achieving the effect of steering control of the combined wheelchair.

[0040] The lower fixed support member supports the wheelchair body, and the lower fixed support member includes a bearing plate 19 rotatably set on the bearing seat 1, a rotating docking port is provided on the bearing plate 19 on one side, and a plug-in terminal block 20 connected to the rotating docking port via a connecting shaft is fixedly connected to the bearing plate 19 on the other side, and a plug-in port 21 adapted to the plug-in terminal block 20 is provided on the inner wall of the rotating docking port.

[0041] It should be noted that the bearing plate 19 is directly located (set) below the bearing nylon seat component and can bear the weight of the patient.

[0042] The semi-foldable wheelchair body comprises an "L"-shaped load-bearing seat 1, a footrest 2 is arranged at the front end of the load-bearing seat 1, a load-bearing nylon seat part 3 and a retractable nylon backrest part 4 are arranged between the load-bearing seats 1 arranged opposite to each other, a protective handrail 5 is arranged at the upper end of the load-bearing seat 1, and a driving end seat 6 is arranged at the lower part;

[0043] A combined connecting piece for fixing the driving end seat 6 is provided on the driving end seat 6; further, the combined connecting piece includes a locking port 22 opened on the side wall of the driving end seat 6 on one side, an L-shaped docking piece 23 is provided on the driving end seat 6 on the other side, a control chamber is opened in the driving end seat 6, an inclined cross bar 24 is provided in the control chamber, the driving end seat 6 is connected to a bevel locking block through a threaded control column 25, and a blocking limit shaft 26 inserted into the plug-in port 21 is fixedly connected to the bottom of the bevel cross bar 24.

[0044] A main driving wheel 7 is arranged in the driving end seat 6 on one side, and a combined auxiliary wheel assembly is arranged in the driving end seat 6 on the other side. The combined auxiliary wheel assembly can control the change of the inner diameter through the adjustment assembly.

[0045] A circular opening is provided on the driving end seat 6 located on one side of the main driving wheel 7 to provide space for accommodating the combined auxiliary wheel assembly.

[0046] Furthermore, the main driving wheel 7 includes an annular opening opened in the driving end seat 6, and the main driving wheel 7 is annularly sleeved on the inner wall of the annular opening, and the contact parts are rotatably connected through bearings.

[0047] The combined auxiliary wheel assembly includes a plurality of arc-shaped support plates 27 distributed in a circle, the arc-shaped support plates 27 are slidingly connected to each other through elastic metal parts 28, the outer wall of the arc-shaped support plates 27 is provided with a rubber air wheel 29, and the arc-shaped support plates 27 are slidingly connected to the inner wall of the driving end seat 6 through an L-shaped sliding limiter 30.

[0048] Furthermore, the adjustment assembly includes an adjustment threaded shaft 31 rotatably connected to the inner wall of the driving end seat 6 , and a threaded adjustment ring 32 is rotatably connected to the outer wall of the adjustment threaded shaft 31 , and the threaded adjustment ring 32 is connected to the arc support plate 27 through a linkage adjustment rod 33 .

[0049] By rotating the adjusting threaded shaft 31, the threaded adjusting ring 32 is moved, thereby changing the inner diameter of the arc-shaped support plate 27 through the linkage adjusting rod 33, and the rubber air wheel 29 originally used for support is retracted inward, so that the two combined auxiliary wheel assemblies in the middle of the two combined wheelchairs are in a storage state and do not contact the ground, thereby facilitating the control and rotation of the combined wheelchair.

[0050] When the present invention is used, the wheelchair has an independent use mode and a combined use mode, which can meet the needs of individual use and double use respectively. When the wheelchair is used, the wheelchair is opened, and the two half-folded wheelchair bodies that were originally stored together are combined. Specifically, the lower fixed support member arranged at the bottom of the wheelchair is opened, and the upper control linkage member arranged at the top is opened synchronously, and the two rotating connected bearing plates 19 are pushed upward so that the bearing plates 19 tend to be horizontal, and the plug-in terminal block 20 arranged at the end of the bearing plates 19 is inserted into the plug-in interface 21, and the fastening locking knob 14 arranged on the upper control linkage member is controlled as needed to achieve the effect of effectively locking the control linkage plate 10 on the upper control linkage member, thereby ensuring that the wheelchair can be used by an individual in the independent use mode;

[0051] When the combined use mode is used by two people, it is convenient for the nursing staff to operate. The two adjacent half-folded wheelchair bodies can be moved closer by controlling the fastening locking knob 14 on the control link plate 10, thereby shortening the distance between the wheelchairs and facilitating the control of the two groups of wheelchairs to move. After adjusting the width of the two wheelchairs, the wheelchairs are controlled to be combined, and the L-shaped docking piece 23 arranged on the drive end seat 6 is inserted into the locking port 22, and the inclined cross bar 24 is moved downward by rotating the threaded control column 25, and the locking port 22 is blocked by the blocking limit shaft 26 to lock the L-shaped docking piece 23, so that the two wheelchairs are locked together, and the threaded adjustment shaft 31 is rotated to move the threaded adjustment ring 32, so that the inner diameter of the arc support plate 27 is changed by the linkage adjustment rod 33, and the rubber air wheel 29 originally used for support is retracted inward, so that the two combined auxiliary wheel assemblies in the middle of the two combined wheelchairs are in a storage state and do not contact the ground, thereby facilitating the control and steering of the combined wheelchair.

[0052] At this time, the pushing handles 11 on both sides can be moved horizontally so that the pushing handles 11 connected to the slide slots 15 and the fixed pushing handles 11 can be brought closer together. When they are brought closer together, the traction control board 17 will be pulled into an inclined state. In this state, when it is necessary to control the wheelchair to turn, it is only necessary to press the pushing handles 11, even if the pushing handles 11 are moved horizontally, so that the traction control board 17 can control the wheelchair away from one side, thereby realizing flexible control of the combined wheelchair and meeting the operational needs of medical staff.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
