Abstract
The invention relates to a leg support rod locking mechanism of a rehabilitation robot, which is characterized in that a handle, a gland and a buckle form a reliable locking mechanism to firmly position a support rod, a smooth round surface between a shaft sleeve and the support rod is contacted, so that the support rod is very stable, labor-saving and noiseless in telescopic adjustment, and a tail end screw on a handle screw ensures that the handle is not separated from the tail end of a stroke, so that the leg support rod locking mechanism has reliable performance and excellent practical effect, and solves the problems that the support rod of the existing device is not firm in positioning, the support rod is harder to adjust, the movement is not smooth enough, the noise is high, a plastic handle is easy to twist and remove and the.
Description
Technical Field
The invention belongs to the technical field of rehabilitation medical robots, and relates to a leg supporting rod locking mechanism of a rehabilitation robot.
Background
China has a large population, cerebral palsy and cerebral apoplexy patients have a large number, the population aging is serious day by day, and a large number of patients need rehabilitation medical training every year. The most effective training mode for patients with limb disabilities at present is to adopt an exoskeleton robot to perform assisted training on the patients. The leg rehabilitation training device is mainly characterized in that the legs of a human body are fixed on the exoskeleton mechanism, and the legs of the human body are driven by a motor at the joints of the exoskeleton mechanism to perform rehabilitation training.
Therefore, the leg structure of the rehabilitation medical robot is a core structure of the exoskeleton. At present, the bracing piece locking mechanism of shank structure ubiquitous bracing piece location is firm inadequately, and the bracing piece adjustment is harder and remove not smooth enough, and the noise is big and the plastics handle is easily twisted and is taken off the scheduling problem, consequently urgent needs a firm, laborsaving, steady, bracing piece locking mechanism that low noise and plastics handle do not deviate from.
Disclosure of Invention
Technical problem to be solved
In order to avoid the defects of the prior art, the invention provides a leg support rod locking mechanism of a rehabilitation robot, which solves the problems that the support rod of the prior device is not firm enough in positioning, the support rod is difficult to adjust, the movement is not smooth enough, the noise is high, a plastic handle is easy to unscrew and the like.
Technical scheme
A leg supporting rod locking mechanism of a rehabilitation robot comprises a thigh bone 1; the utility model is characterized in that the utility model also comprises a shaft sleeve 2, a pin shaft 3, a gland 5, a handle 6, a buckle 8 and a leg support bar 10; the L-shaped leg support rod 10 passes through a through hole on the flange above the femur 1, and a shaft sleeve 2 is arranged between the leg support rod 10 and the through hole; a screw rod of the handle 6 penetrates through the gasket 7 and a through hole 11 at one end of the L-shaped gland 5 and is screwed into a threaded hole 13 on the buckle 8 to be fixed with the tail end screw 4 at the lower part of the buckle 8; the buckle 8 is positioned at the right-angled bottom of the square flange, the lugs 15 at the two ends limit the shaft sleeve in the through hole of the square flange, and the buckle 8 and the square flange are fixed by two screws 9; the pin shaft 3 penetrates through a through hole at the right angle of the square flange and a through hole 12 at the right angle part of the gland 5 to fix the gland 5 and the square flange; the handle 6 is loosened or tightened to adjust or fix the position of the support pole 10.
The contact surface of the support rod 10 and the shaft sleeve 2 is round and smooth.
The handle 6 is made of plastic.
Advantageous effects
The invention provides a leg support rod locking mechanism of a rehabilitation robot, which is characterized in that a reliable locking mechanism is formed by a handle, a gland and a buckle to firmly position a support rod, a smooth round surface between a shaft sleeve and the support rod is contacted, so that the support rod is very stable, labor-saving and noiseless in telescopic adjustment, and a tail end screw on a handle screw ensures that the handle is not separated from the tail end of a stroke, so that the leg support rod locking mechanism has reliable performance and excellent practical effect, and solves the problems that the support rod of the existing device is not firm enough in positioning, the support rod is more laborious to adjust, the movement is not smooth enough, the noise is high, a plastic handle is easy to twist and unt.

The thigh bone 1, the shaft sleeve 2, the pin shaft 3, the tail end screw 4, the gland 5, the plastic handle 6, the gasket 7, the buckle 8, the screw 9, the leg support rod 10, the through hole on the gland 5 of 11, the through hole on the right-angle part of 12 gland 5, the threaded hole 13 on the buckle 8 of 13, the hole of the screw 9 on the buckle 8 of 14, and the ears at two ends of the buckle 8 of 15.
Detailed Description
The invention will now be further described with reference to the following examples and drawings:
the leg support rod locking mechanism of the embodiment mainly comprises a femur 1, a shaft sleeve 2, a pin shaft 3, a tail end screw 4, a gland 5, a plastic handle 6, a gasket 7, a buckle 8, a screw 9 and a leg support rod 10.
A screw rod of the plastic handle 6 penetrates through the washer 7 and the elliptical hole on the gland 5 and is screwed into a threaded hole on the buckle 8, and the tail end screw 4 is screwed into a threaded hole at the end part of the handle screw rod from the lower part of the buckle 8; two shaft sleeves 2 are arranged in corresponding holes on the femur 1, and then the arranged buckles 8 are arranged at the right-angle bottom positions of the square flanges shown in figure 2, so that the lugs at the two ends of the buckles limit the shaft sleeves and prevent the shaft sleeves from loosening and falling off in the use process. The gland 5 is fixed by the pin shaft 3, the buckle 8 is fixed by two screws 9, and finally the support rod 10 penetrates into the shaft sleeve 2. Because the contact surface of the support rod 10 and the shaft sleeve 2 is round and smooth, the adjustment of the position of the support rod is smooth and noiseless. When the locking is needed, the plastic handle 6 is screwed, the flat opening of the supporting rod 10 is pressed tightly by the gland 5, and the supporting rod 10 is firmly locked; when the supporting rod 10 is loosened, the plastic handle 6 is reversely screwed, the supporting rod 10 is loosened, and if the plastic handle 6 is continuously screwed after the supporting rod 10 is loosened, the screw rod is limited by the tail end screw 4 after the screw rod runs out of a given stroke, so that the plastic handle is prevented from being unscrewed.
