Detailed Description
Example (b): referring to fig. 1 to 3, an adjustable leg fracture walking aid comprises two support frames 10 and an intermediate connecting beam 20, wherein each support frame 10 comprises two vertical support legs 11, a first extension part 12 extending inwards and horizontally is formed at the top end of one vertical support leg 11, a second extension part 13 extending inwards and horizontally is formed at the top end of the other vertical support leg 11, the first extension part 12 is positioned above the second extension part 13, and an oblique connecting part 14 is formed between the second extension part 13 and the first extension part 12;
the middle parts of the bottom surfaces of the two vertical supporting leg parts 11 are formed with screw connection adjusting holes 111, vertical adjusting screw rods 15 are screwed in the screw connection adjusting holes 111, and the bottom ends of the vertical adjusting screw rods 15 extend out of the bottom surfaces of the vertical supporting leg parts 11 and are fixed with wear-resistant blocks 16.
Further, a lock nut 17 is screwed to a lower portion of the vertical adjusting screw 15, and a top surface of the lock nut 17 is pressed against a bottom surface of the vertical support leg 11.
Further, an elastic pad 18 is fixed to the bottom surface of the wear-resistant block 16.
Furthermore, the outer side walls of the first extension portion 12 and the second extension portion 13 are fixed with the elastic protection layer 1.
Further, a middle support rod 2 is welded and fixed between the middle parts of the two vertical support leg parts 11.
