[0001] This utility model relates to the field of medical devices, and in particular to a wheelchair with a detachable walking aid. Background Technology

[0002] Wheelchairs and walking aids are commonly used assistive tools in medical settings, generally used for rehabilitation training of the injured, sick, and disabled. Wheelchairs are used for patients' mobility, while walking aids are used for patients' walking exercises. They are often used alternately as needed, but both assistive tools are large and heavy, making them inconvenient to carry. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: in order to solve the problem of the inconvenience of patients carrying both wheelchairs and walking aids, this utility model provides a wheelchair with a detachable walking aid, which can be assembled into a walking aid by disassembling and reassembling the parts, thus achieving the effect of dual use in one unit and meeting the needs of two types of rehabilitation training.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a wheelchair with a detachable walking aid, including a frame and a backrest assembly; the backrest assembly is snapped onto the top of the frame and located on one side of the seat;

[0005] The backrest assembly includes two outer cylindrical rods, a folding mechanism disposed on the outside of the outer cylindrical rods, and backrest panels that can be spliced ​​together; the outer cylindrical rods are vertically snapped onto the top of the frame, and the two outer cylindrical rods are parallel to each other; the outer cylindrical rods correspond one-to-one with the backrest panels, and the two outer cylindrical rods and the backrest panels together form a whole; the rod body of the outer cylindrical rod is slidably fitted with a connector, one side of the connector is hinged to the corresponding backrest panel, and one side of the folding mechanism is slidably connected to the backrest panel;

[0006] The folding mechanism includes a support frame, a movable seat, and a fixed seat. The support frame has a C-shaped cross-section and is located on the outside of the outer cylinder rod. The support frame and the outer cylinder rod are assembled with a clearance fit. The movable seat is sleeved on the outer cylinder rod, and one side of the movable seat is rotatably connected to the support frame. The fixed seat is sleeved on the outer cylinder rod, and the fixed seat is located on one side of the movable seat. A connecting rod is hinged to one side of the fixed seat, and the end of the connecting rod away from the fixed seat is hinged to the support frame.

[0007] Therefore, when a walking aid is needed, the outer cylinder rod is separated from the frame, and the backrest assembly is separated from the frame. Then, the movable seat moves closer to the fixed seat, and the connecting rod pushes the support frame to unfold, realizing the unfolding of the folding mechanism, so that the support frame and the outer cylinder rod are in an intersecting state. At this time, the backrest is placed horizontally between the support frame and the outer cylinder rod. Thus, the backrest assembly is assembled into a walking aid mode, achieving a convenient and quick effect.

[0008] Furthermore, the connector includes a sliding sleeve and a base plate; the sliding sleeve is movably sleeved on the outer cylinder rod, and the sliding sleeve is located inside the support frame; the base plate is disposed on one side of the sliding sleeve, and one side of the base plate is smoothly connected to the sliding sleeve, forming a U-shaped cavity between the base plate and the sliding sleeve; a rotating shaft is fixedly installed on the side of the base plate away from the sliding sleeve, and the rotating shaft is rotatably connected to the corresponding backrest plate; thus, the backrest plate can move on the outer cylinder rod, and the U-shaped cavity adapts to the support frame so that the backrest plate is not disturbed by the support frame when it moves or rotates.

[0009] Furthermore, a rotating column is fixedly installed on the side of the movable seat, and the axis of the rotating column is perpendicular to the axis of the outer cylinder rod. The side of the rotating column away from the movable seat is fitted with the support frame with a clearance fit. Thus, the movable seat moves axially along the outer cylinder rod with the support frame, and the support frame can rotate with the rotating column as the fulcrum. As a result, the hinge point position between the support frame and the outer cylinder rod can change, so that the support frame can completely overlap with the outer cylinder rod when the folding mechanism is retracted.

[0010] Furthermore, the connector is located between the movable seat and the fixed seat, and a connecting rod is provided between the movable seat and the connector; an mounting component is fixedly installed on the side of the movable seat, the bottom of the mounting component is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fitted with the top of the connector using a transition fit; thus, when the movable seat moves, the connector is pushed to move synchronously through the connecting rod; this facilitates the later horizontal placement of the backrest panel.

[0011] Furthermore, the support frame has a sliding groove on its side, and the backrest panel is fixedly provided with a cylindrical sliding key on the side near the support frame. The sliding key is assembled with the sliding groove. Thus, when the support frame is rotated and unfolded, the sliding key moves from one end away from the movable seat to the other end in the sliding groove, thereby changing the backrest panel from a vertical state to a horizontal state, which is convenient for the patient to rest when using the walking aid.

[0012] Furthermore, an inner rod is movably provided at the top of the outer cylinder rod, and the inner rod is vertically arranged inside the outer cylinder rod; a gear adjustment structure is provided between the outer cylinder rod and the inner rod; the gear adjustment structure adopts an existing protruding pin and multiple groove mating structure, thereby enabling the height of use to be adjusted according to the patient's height, improving the comfort of use.

[0013] Furthermore, a handle is hinged to one end of the inner rod outside the outer rod; the handle is provided with an armpit support, and the angle between the handle and the inner rod is within 90 degrees to 180 degrees.

[0014] Furthermore, a groove is provided on the top of the movable seat, the groove penetrates the side wall of the movable seat, and the width of the groove is greater than the width of the hinge of the handle; thus, when the folding mechanism is retracted, the movable seat does not hinder the movement of the handle when it is at the top of the outer cylinder rod.

[0015] Furthermore, the backrest panel includes a first connecting plate, a middle plate, and a second connecting plate that are hinged together in sequence. All three connecting plates are made of soft panels. The first connecting plate is located on one side of the outer cylinder rod, and its side is fitted with the pivot shaft with a clearance fit. The second connecting plate has a riveting structure on its side away from the middle plate. Thus, the second connecting plates of the two backrest panels are riveted together to connect the two backrest panels. The first connecting plate, the middle plate, and the second connecting plate that are hinged together in sequence can be folded for storage.

[0016] Furthermore, multiple intermediate plates are provided, and the multiple intermediate plates are hinged together in sequence. The connecting plate one and the connecting plate two are respectively hinged to the adjacent intermediate plates.

[0017] Furthermore, an auxiliary wheel is movably mounted on the bottom of the outer cylinder rod; thus, when the backrest assembly is unfolded into a walking aid, the auxiliary wheel can be mounted on the bottom of the outer cylinder rod to assist the patient in moving.

[0018] The beneficial effects of this utility model are as follows:
