[0026] A backrest 3 is provided on the right side of the seat cushion 2;

[0027] A telescopic handle 6 is provided on both the front and rear sides of the backrest 3;

[0028] The front and rear outer walls of the backrest 3 are fixedly connected with a fixing frame a5 to limit the position of the telescopic handle 6, the front and rear outer walls of the seat cushion 2 are fixedly connected with a fixing frame b10, and the right sides of the two fixing frames b10 are provided with a positioning wheel 9, and the front end outer wall of the fixing frame a5 is fixedly connected with an adjusting wheel 7 near the lower side, and a rotating shaft 8 is transmission-connected between the fixing frame a5 and the fixing frame b10 to limit the inclination angle of the fixing frame a5, and a plurality of movable footrests 15 are provided on the left side of the legrest 1, and a fixed column 13 is provided on the right side of the movable footrest 15 to limit the position of the movable footrest 15 The lower side of the seat cushion 2 is provided with a plurality of moving wheels 12. When the user needs to lay the foldable wheelchair flat during use, the legrest 1 can be lifted upwards, and then the backrest 3 can be pressed downwards, so that the legrest 1, the seat cushion 2 and the backrest 3 are on the same horizontal plane, and then the telescopic handle 6 is rotated 180 degrees clockwise, and the telescopic handle 6 is extended to touch the ground to complete the adjustment, and then the user can lie flat on the foldable wheelchair. When it is not necessary to lie flat, the legrest 1 and the backrest 3 are reset, and the telescopic handle 6 is retracted and then the angle is adjusted to complete the change of sitting posture;

[0029] A plurality of adjustment holes a18 are provided on the circular outer wall at the right end of the fixed column 13, an extension rod 21 is arranged inside the fixed column 13 to limit the height adjustment range of the movable footrest 15, a plurality of adjustment holes b20 which pass through the right end of the extension rod 21 are provided on the outer wall, and a fixing screw 19 which passes through the adjustment holes a18 and b20 to the left is arranged on the right side of the fixed column 13 to limit the position of the extension rod 21. When the user sits on the seat 2 and the sole of the foot cannot contact the movable footrest 15, the fixing screw 19 can be rotated counterclockwise to remove it, and then the extension rod 21 can be moved upward to make the movable footrest 15 contact the sole of the user's foot, and then the fixing screw 19 can be passed to the left through the adjustment holes a18 and b20 to fix the position of the movable footrest 15, thereby completing the position restriction.

[0030] like Figure 4 and Figure 5 As shown, a nut 22 is threadedly connected to the other side of the fixing screw 19 to limit the position of the fixing screw 19, and a movable groove 23 is opened inside the fixing column 13 to allow the extension rod 21 to move up and down, and the adjustment hole a18 and the adjustment hole b20 are the same size, and the extension rod 21 is made of aluminum alloy.

[0031] After the fixing screw 19 is inserted into the adjustment hole a18 and the adjustment hole b20, the leaked part can be threadedly connected through the nut 22 to limit the position of the fixing screw 19 to prevent the fixing screw 19 from coming out. The extension rod 21 moves up and down inside the movable groove 23 when adjusting the position.

[0032] like Figure 1 and Figure 2As shown, the uppermost sides of the right end outer walls of the two fixed frames a5 are fixedly connected with push rods 4, the left end outer walls of the two positioning wheel discs 9 are fixedly connected with bottom frames b16 to limit the position of the fixed column 13, the front end outer wall of the bottom frame b16 is fixedly connected with the bottom frame a11 near the upper side to limit the position of the moving wheel 12, and a connecting rod 14 is arranged between the movable foot pedal 15 and the fixed column 13 to limit the position of the movable foot pedal 15.

[0033] The portable wheelchair can be moved by grasping the push rod 4 and pushing it. The bottom frame a11 and the bottom frame b16 can be used to lift the seat cushion 2 and increase the stability of the bottom while limiting the position of the moving wheel 12.

[0034] like Figure 2 and Figure 3 As shown, a hand-pull switch 17 is provided between the two rotating shafts 8 to unlock the fixing of the rotating shaft 8 to the backrest 3, and the telescopic handle 6 can be rotated clockwise at an angle of 180 degrees and extended.

[0035] By pressing the hand-pull switch 17, the rotating shaft 8 can be unlocked, and the backrest 3 can be quickly pressed down to be on the same horizontal plane with the seat cushion 2. When the leg rest 1, the seat cushion 2 and the backrest 3 are on the same horizontal plane, the telescopic handle 6 can be rotated to extend the telescopic handle 6 to support the backrest 3.

[0036] like Figure 1 and Figure 2 As shown, a headrest is fixedly connected to the upper side of the backrest 3, the movable footrest 15 can be adjusted in angle upward for storage, the legrest 1 can be adjusted in angle upward, and a buckle is fixedly connected to the front end outer wall of the positioning wheel 9 to pass through the gear position inside the adjustment wheel 7 to limit the tilt angle of the backrest 3.

[0037] The headrest increases the comfort of the user when lying flat or sitting. When the movable footrest 15 is not needed, the movable footrest 15 can be adjusted upward for storage. When the hand-pull switch 17 is pressed, the buckle on the front side of the positioning wheel 9 is contracted. At this time, the backrest 3 can be pulled backward to adjust the angle. After adjusting to a suitable angle, release the hand-pull switch 17, and the buckle can be inserted into the inside of the adjustment wheel 7, thereby limiting the tilt angle of the backrest 3.

[0038] The implementation principle of this embodiment is as follows: when the user needs to lay the foldable wheelchair flat during use, the legrest 1 can be lifted upwards, and then the hand-pull switch 17 can be pressed downwards to make the legrest 1, the seat cushion 2 and the backrest 3 on the same horizontal plane, and then the telescopic handle 6 can be rotated 180 degrees clockwise, and the telescopic handle 6 can be extended to touch the ground to complete the adjustment, and then the user can lie flat on the foldable wheelchair. When it is not necessary to lie flat, the legrest 1 and the backrest 3 can be reset, and the telescopic handle 6 can be retracted and then the angle can be adjusted to complete the sitting posture. The user can sit on the seat 2 and step on the movable footrest 15, and the outsider can hold the push rod 4 to drive the moving wheel 12 to rotate to complete the movement of the portable wheelchair. When the user sits on the seat 2 and the sole of the foot cannot touch the movable footrest 15, the fixing screw 19 can be rotated counterclockwise to remove it, and then the extension rod 21 is moved upward to make the movable footrest 15 contact the sole of the user's foot, and the fixing screw 19 is passed to the left through the adjustment hole a18 and the adjustment hole b20 to complete the position fixation of the movable footrest 15, thereby completing the position restriction.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
