Detailed Description

Referring to fig. 1-3, a medical crutch for patient rehabilitation comprises a sleeve 2 arranged on two sides of the top end of a bottom plate 1, wherein the sleeve 2 is hollow and is movably provided with a bracket 3, an arc-shaped supporting plate 5 is connected between the top ends of the bracket 3 through a fixing block 4, a stand column 6 is arranged at the center of the top end of the bottom plate 1, a rotating shaft connected with a handle 7 is arranged on the outer wall of the stand column 6, one end of the rotating shaft penetrates through the stand column 6 and extends to a first conical gear 8 inside the stand column 6, a second conical gear 10 fixed on a threaded rod 9 is meshed and transmitted on the outer wall of the first conical gear 8, a circular ring 11 is spirally transmitted on the outer wall of the threaded rod 9, and two ends of the circular ring 11 are connected with the bracket 3 through a cross beam 12.

The concrete embodiment of this scheme does, arc backup pad 5 top viscidity is fixed with the foam-rubber cushion, and is integrated into one piece between arc backup pad 5 and the fixed block 4, the domatic has all been seted up to arc backup pad 5 top both sides, the central fixedly connected with rubber pad in bottom 1 bottom, the domatic on the arc backup pad 5 sets up its essentially just a fillet, can prevent like this that even take place to touch also to avoid producing the damage, its principle has just increased the atress face, and then makes the atress disperse, and 1 bottom center fixedly connected with rubber pad of bottom can be further increase buffering protection effect, increases the security of device.
