Walking stick for old people

[0027] Basic as attached figure 1 As shown: crutches for the elderly, including crutch body 1 and handrails, the bottom of the crutch body 1 is welded with a vertical support rod 17, and the bottom of the support rod 17 is bonded with a rubber block 18, so that the bottom of the crutch body 1 can be enlarged The friction with the ground makes the crutches more stable when used. The armrest is located at the top of the crutch body 1, and the armrest includes a fixed part 6 and three rotating parts 4 below the fixed part 6. The fixed part 6 and the rotating part 4 are all rectangular shapes placed horizontally, and the lengths of the fixed part and the rotating part are the same. 25cm in width, 5cm in width, and 1cm in thickness. The fixed part 6 is welded on the top of the crutch body 1, and the rotating part 4 is connected to the top of the crutch body 1 by lateral rotation. Specifically, the top of the crutch body 1 is provided with three annular grooves 3. The top of the crutc

[0034] It is easy to understand that the rotating tube 15 can be slidably connected in the containing tube 14, so that the rotating tube 15 slides in the containing tube 14, thereby changing the length of the legs, the containing tube 14 can be provided with blocks, and the rotating tube 15 can be provided with The locking slot, through the cooperation of the locking block and the locking slot, the receiving tube 14 can lock the rotating tube 15 to prevent the relative sliding between the rotating tube 15 and the receiving tube 14 and realize the relative fixing between the rotating tube 15 and the receiving tube 14 .

[0036] It is easy to understand that a gear is coaxially welded on the part that can be connected through the rotation of the top of the leg, and the gear is meshed with a vertically arranged rack. The rack is vertically slidably connected in the crutch body 1, and the top of the rack is welded to the slide plate 27 , when the supporting foot swings like this, the supporting foot drives the gear to rotate, and the gear drives the rack to move vertically, thereby driving the slide plate 27 to move vertically. In this embodiment, the movement of the slide plate 27 is realized through the cooperation of the gear and the rack. Compared with using the pull cord 12 to pull the slide plate 27 to move, it can prevent the draw cord 12 from breaking easily during use, thereby improving the service life of the crutch.
