[0045] First embodiment

[0046] like Figure 1 As shown, the detachable walking aid comprises:

[0047] Two single-sided bodies 100, each of which includes a front side frame 110 and a rear side frame 120 of different shapes, wherein the upper portion of the front side frame 110 is connected to the front side of the upper support 130, and the upper portion of the rear side frame 120 is connected to the rear side of the upper support 130;

[0048] At least one intermediate body 200, wherein the intermediate body 200 is connected between the two single-sided bodies 100;

[0049] The intermediate body 200 can be removed relative to the single-side body 100, and the front side frame 110 and the rear side frame 120 can be separated. The separated front side frame 110 and the rear side frame 120 can be used as single-point turning respectively.

[0050] The intermediate body 200 is used to connect the two unilateral bodies 100 to ensure the stability of the walker structure. The walker has two front side frames 110 and two rear side frames 120, which correspond to four support points respectively. In this case, the walker is a four-legged crutch, and the two upper supports 130 are used to support the patient's hands respectively. The front side frame 110 and the rear side frame 120 can be separated, and the separated front side frame and the rear side frame 120 can be deformed and used as a single-point crutch, which can meet different usage requirements without the need for additional purchase.

[0051] like Figure 1 As shown, the front side frame 110 includes:

[0052] A rotating rod 111, the upper portion of which is connected to the front side of the upper support 130;

[0053] A lower support 112, the rear side of which is connected to the lower portion of the rotating rod 111;

[0054] A front lower rod 113, the upper portion of which is connected to the front side of the lower support 112;

[0055] The rotating rod 111 drives the upper support 130 to rotate relative to the lower support 112 .

[0056] The lower support 112 and the upper support 130 are both arranged horizontally, and the rotating rod 111 is roughly Z-shaped, so that the current upper support 130 is located at the rear side of the lower support 112. When the front side frame 110 is used as a single-point turning, the upper support 130 is rotated by the rotating rod 111 to make the upper support 130 perpendicular to the lower support 112, and the length of the front lower rod 113 is adjusted at the same time, so that the upper support 130 is changed from the original hand support to the underarm support, and the lower support 112 is changed to the hand support.

[0057] refer to Figure 2 The upper support 130 is retractable and includes a fixed portion 131 and a retractable portion 132. The upper portion of the rotating rod 111 is connected to the fixed portion 131, and the retractable portion 132 is slidably disposed in the fixed portion 131. In this way, when the upper support 130 is rotated 90° relative to the lower support 112, the retractable portion 132 is pulled out of the fixed portion 131 and fixed by bolts, thereby increasing the length of the upper support 130, which is beneficial for supporting the patient's armpits.

[0058] Furthermore, the front lower rod 113 can also be telescopic, and also includes a fixed part and a telescopic part. The fixed part is provided with a plurality of circular holes, and the plurality of circular holes are spaced apart along the length direction of the fixed part. The relative distance between the telescopic part and the fixed part is adjusted to obtain the front lower rod 113 of a corresponding length, and then a bolt is passed through the corresponding circular hole of the fixed part to lock it with the telescopic part, thereby adjusting the length of the front lower rod 113.

[0059] like Figure 1 As shown, the rotating rod 111 includes:

[0060] A rotating upper rod 111a, wherein the upper portion of the rotating upper rod 111a is connected to the front side of the upper support 130;

[0062] The upper part of the rotating lower rod 111b is an opening, and the lower part of the rotating upper rod 111 is inserted into the opening of the upper part of the rotating lower rod 111b, and the rotating upper rod 111 can rotate relative to the rotating lower rod 111b, and can be fixed by bolts after the rotation position is determined, so that the rotating upper rod 111a drives the upper support 130 to rotate.

[0063] like Figure 1 As shown, the rear side frame 120 includes:

[0064] A rear curved rod 121, the front end of which is connected to the rear side of the upper support 130;

[0065] The rear lower rod 122 has an upper portion connected to the rear end of the rear curved rod 121 .

[0066] The rear lower rod 122 is retractable. When the rear frame 120 is used as a single-point turning, the length of the rear lower rod 122 can be adjusted to meet the height of the rear frame 120 used as a single-point turning, wherein the upper support 130 can be used for hand support.

[0067] The rear curved rod 121 can be detachably connected to the rear side of the upper support 130 by screw connection, sleeve connection, etc. Similarly, the rotating rod 111 of the front frame 110 can be detachably connected to the front side of the upper support 130 by screw connection, sleeve connection, etc.

[0068] like Figure 1 As shown, the single-sided body 100 further includes:

[0069] The side connector 140 is connected between the front side frame 110 and the rear side frame 120 to improve the stability of the structure.

[0070] Furthermore, one end of the side connector 140 is connected to the front lower rod 113 of the front side frame 110, and the other end of the side connector 140 is connected to the rear lower rod 122 of the rear side frame 120, wherein the ultra-small angle between the front lower rod 113 and the rear lower rod 122 is 60° to 45°, further improving the stability of the structure.

[0071] like Figure 1 As shown, the lower parts of the front side rod 110 and the rear side rod 120 are respectively connected to support 300. Specifically, the lower parts of the front side lower rod 113 and the rear side lower rod 122 are respectively connected to support 300.

[0072] like Figure 1 As shown, there are two intermediate bodies 200, which are arranged from top to bottom. The intermediate body 200 located at the top is connected between the rear curved rods 121 of the two single-sided bodies 100, and the two ends of the intermediate body 200 located at the bottom are respectively connected to connecting tubes 210, the intermediate body 200 and the connecting tube 210 are perpendicular to each other, the upper end of the connecting tube 210 is connected to the rear end of the rear curved rod 121, and the lower end of the connecting tube 210 is connected to the rear lower rod 122.

[0073] The two connecting pipes 210 and the intermediate body 200 can be connected as one piece, which is convenient for disassembly and assembly.
