DETAILED DESCRIPTION

[0044] 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. Example

[0045] See Figures 1 to 6 As shown, a multifunctional walking-assisting wheelchair dual-purpose vehicle comprises two side wheel frames 1 of the same structure, a universal wheel 2 is fixed at the bottom of the side wheel frames, and a folding cushion structure 3 is arranged between the two side wheel frames. In this embodiment, the two side wheel frames can be folded or unfolded through the folding cushion structure to realize the function of a wheelchair or a walking-assisting frame, and the universal wheel is a conventional structure of the prior art, so it is not recorded in detail. At the same time, in this embodiment, the side wheel frame comprises a frame body 1-1, two wheel columns 1-2 and a handle lifting armrest body 1-3; when installed, the two wheel columns are fixed at the two ends of the bottom edge of the frame body, and the universal wheel is fixed at the bottom end of the wheel column; the handle lifting armrest body is arranged on the top of the frame body; the frame body and the wheel column are integrally formed, and can also be fixed by a screw rod, which is mainly used to connect the frame body with the universal wheel. It is easy to fold and fold, convenient for travel and carrying, and tailor-made for people with unchanged walking to create a modern and aesthetically pleasing walking-assisting wheelchair trolley.

[0046] In actual application, a footrest 4 and a backrest 5 are also provided on the side wheel frame; wherein, a C-shaped block 6 is provided on the footrest, and the C-shaped block of the footrest is detachably sleeved on the bottom end of the wheel column; through the above structure, the disassembly and assembly operation of the footrest can be facilitated, and in order to improve the stability and reliability of disassembly and assembly, a connecting sleeve 7 is provided on the top of the universal wheel; the bottom end of the wheel column is inserted into the connecting sleeve and fixed by a screw; at least one positioning convex strip 8 is provided on the outer wall of the connecting sleeve; a positioning groove 9 matching the position of the positioning convex strip is provided on the inner wall of the C-shaped block; the C-shaped block is sleeved on the outer side of the connecting sleeve, and the positioning convex strip is inserted in the positioning groove for limiting. It is limited by the positioning convex strip and the positioning groove, and after the connecting sleeve is connected with the C-shaped block, sufficient supporting force can be guaranteed, and the stability and reliability of the use of the footrest can be guaranteed.

[0047] In actual application, a vertical slot 10 is fixed on the top of the handle lifting armrest body; vertical plug-in blocks 11 matching the vertical slot are fixed at both ends of the rear backrest body; the vertical plug-in blocks of the rear backrest body are inserted in the vertical slot for limiting position.
