Background
The upper limb movement mechanism adopted on the upper limb exercise rehabilitation products such as an upper limb rehabilitation trainer, a multi-joint active and passive training instrument and the like in the current market has the defects that the wrist of a user can only keep one posture during exercise training due to insufficient freedom of movement of a handle, so that the training effect is greatly reduced, and the long-time training is easy to fatigue.
Disclosure of Invention
The utility model aims to overcome the above problems of the handle of the upper limb rehabilitation training device.
In order to solve the problems of the handle of the prior upper limb rehabilitation training device, the utility model provides a rotary handle for the upper limb rehabilitation training device, which comprises a hand-crank connecting rod, a bearing sleeve and an annular guide rail, wherein one end of the hand-crank connecting rod is provided with a connecting shaft, the hand-crank connecting rod is fixedly connected with one end of the connecting shaft, the bottom of the bearing sleeve is provided with a through hole, the other end of the connecting shaft is arranged in the through hole in a penetrating way and is rotationally connected with the bearing sleeve through a bearing, the outer side of the annular guide rail is provided with a connecting flange which is fixedly connected with the annular guide rail, the connecting flange is fixedly connected with the bearing sleeve through a bolt, the inner surface of the annular guide rail is provided with a chute, set up a plurality of arc slider in the spout, arc slider can slide in the spout, sets up the handle in that the annular rail is inside, hand and both ends respectively with arc slider fixed connection, can drive arc slider and slide in the spout of annular rail when the handle is rotatory.
Further set up the screw hole on the hand turns the connecting rod, set up the screw thread at connecting axle one end, hand turns the connecting rod and passes through threaded connection with the connecting axle to set up fastening bolt at the connecting axle tip.
The connecting flange is further welded with the annular guide rail.
The arc-shaped sliding blocks are four blocks.
And further, mounting holes are formed in the overlapping positions of the connecting flanges and the annular guide rail along the radius direction of the annular guide rail.
The utility model has the advantages that: this scheme simple structure, small, low in manufacturing cost, when upper limbs motion training, wrist joint can freely move about, reduces to produce tired feeling because of long-time training, improves the user and uses experience.
