[0019] The utility model is further described below in conjunction with specific embodiments.

[0020] like Figure 1As shown, the foldable wheelchair with adjustable seat width described in the utility model comprises a left frame 1 and a right frame 2, wherein the left frame 1 and the right frame 2 each comprise a left handhold 3 and a right handhold 4 for rear personnel to push, and a left support portion 5 and a right support portion 6 for personnel to sit on, and the left handhold 3 and the left support portion 5, and the right handhold 4 and the right support portion 6 are all fixedly connected.

[0021] A left guide tube 51 and a right guide tube 61 are installed on the top of the left support part 5 and the right support part 6, respectively, and the left guide tube 51 and the right guide tube 61 can be fixed relative to the left support part 5 and the right support part 6 after being lifted to the limit position. Specifically, vertical through holes can be provided on the top of the left support part 5 and the right support part 6, and the left guide tube 51 and the right guide tube 61 can be movably fixedly connected with the left support part 5 and the right support part 6 through the vertical support tube 11, by means of a latch or other forms.

[0022] A flexible seat cushion for people to sit on is connected between the left duct 51 and the right duct 61, and a flexible backrest for people to lean on is also connected between the left hand support 3 and the right hand support 4. At the same time, a first cross bar 52 is fixedly connected between the left duct 51 and the bottom of the right support 6, and a second cross bar 62 is fixedly connected between the right duct 61 and the bottom of the left support 5. The first cross bar 52 and the second cross bar 62 are rotatably connected at the intersection through a rotating shaft.

[0023] Through the above-mentioned structural design, a movable connection can be achieved between the left frame 1 and the right frame 2. By lifting the left guide tube 51 and the right guide tube 61, due to the fixed connection of the first cross rod 52 and the second cross rod 62, the right support part 6 and the left support part 5 will be driven to move relative to each other, and the left frame 1 and the right frame 2 are close to each other. At the same time, combined with the flexible seat cushion and the flexible backrest, a foldable design of the wheelchair is realized, which can reduce the weight when storing or carrying, thereby improving convenience.

[0024] In addition, a plurality of mounting holes 7 which are arranged vertically at equal intervals are respectively provided at the bottom of the left support portion 5 and the right support portion 6, and the bottoms of the first cross rod 52 and the second cross rod 62 are mounted in the mounting holes 7 by screws, thereby realizing a fixed connection between the left guide tube 51 and the right support portion 6, and between the right guide tube 61 and the left support portion 5. Therefore, by changing the position of the mounting holes 7, the rotational connection relationship between the first cross rod 52 and the second cross rod 62 can be utilized to realize the seat width adjustment between the left frame 1 and the right frame 2. Also, due to the presence of the flexible seat cushion and the flexible backrest, the adjustment of the seat width will not cause the wheelchair to be unable to be used normally.

[0025] Two brackets 8 are provided at the top of the left support part 5 and the right support part 6, respectively. The two brackets 8 on the same side are located at the two ends of the left guide tube 51 and the right guide tube 61, respectively, and can limit the lateral movement of the left guide tube 51 and the right guide tube 61. Spacers 9 are provided at the connection positions of the left guide tube 51 and the right guide tube 61 with the left support part 5 and the right support part 6, respectively, for limiting the lateral movement of the left guide tube 51 and the right guide tube 61. A pipe plug is also provided at the bottom of the support tube 11 to improve the overall stability.

[0026] Figure 1 The situation shown is that the first cross bar 52 and the second cross bar 62 are both installed in the lowest installation hole 7. Figure 2 The figure shows the situation that the first cross bar 52 and the second cross bar 62 are both installed in the uppermost installation hole 7. It can be clearly seen that at this time, the distance between the left frame 1 and the right frame 2, that is, the seat width is adjusted.
