In order to ensure the flexibility and stability of the device, the shaft seats 308 are fixedly connected to the left side and the right side of the balancing weight 302, the shaft cavities in the front side and the rear side of the shaft seats 308 are movably connected with the rollers 309, the surfaces of the rollers 309 are lapped on the inner wall of the U-shaped limiting plate 301, and in specific use, the rollers 309 are in contact with the inner wall of the U-shaped limiting plate 301, so that friction is prevented from being generated between the balancing weight 302 and the U-shaped limiting plate 301, and stability and flexibility during training are ensured. Specifically, the equal fixedly connected with damping piece 402 in both sides around the rotary column 403, damping piece 402 and human shell 401's inner wall overlap joint, the positive fixedly connected with sponge board 405 of human shell 401, sponge board 405 is used for providing soft contact for the patient, increases the travelling comfort, and such setting can reach the damping coefficient to damping piece 402 through the position of adjusting damping piece 402 to can increase the 500 dynamics controls of swing arm.
The equal fixedly connected with in-lying abaculus 504 in both ends of compression spring 505, the in-lying abaculus has all been seted up to slider 502 and stopper 503 relative one side, and in-lying abaculus 504 pegs graft in the in-lying abaculus, when using in order to guarantee compression spring 505, according to the difference of training demand, can increase the different spring of coefficient of elasticity, but also can change when compression spring 505 appears damaging, operation when so more convenient the change.
In order to ensure the flexibility of stretching and avoid the situation that arms of a trainer are injured due to blocking, the upper side and the lower side of the inner wall of the movable arm 501 are fixedly connected with a sliding sleeve 508, the upper side and the lower side of the sliding block 502 are movably connected with a pulley 509, and the pulley 509 slides on one side of the inner wall of the sliding sleeve 508. Specifically, one end of the steel wire rope 600 penetrates through the through groove formed in the top of the U-shaped limiting plate 301, so that the moving route of the steel wire rope 600 is increased, and the problem that the steel wire rope 600 is rubbed is solved.
Example 2
When arm extension training is needed, latissimus dorsi is trained simultaneously, a small number of balancing weights 302 are added, the reaction force of the compression springs 505 is larger than that of the balancing weights 302, namely, rehabilitation trainers can more easily and directly pull the balancing weights 302 to move upwards, the compression springs 505 change slightly, the process of pulling the balancing weights 302 enables the movable arms 501 to drive the rotating columns 403 to rotate, and therefore the movable arms 501 are unfolded left and right, the arms can stretch left and right to train openness, and meanwhile, latissimus dorsi is pulled to perform stretching movement in the process of swinging left and right.
Example 3
When arm traction training is needed, the balancing weight 302 is added, at the moment, the counter force of the balancing weight 302 is larger than that of the compression spring 505, namely, a rehabilitation trainer can more easily pull the handle 507 to compress the spring 505 downwards, so that the handle 507 moves downwards along the sliding groove 505, the rotating column 403 basically keeps not rotating due to the fact that the balancing weight 302 is heavy, the arm finishes traction training in the process of pulling the handle, and finally, after the compression spring 505 is compressed to a certain degree, the rehabilitation trainer continues to apply force downwards, so that the balancing weight is pulled to move upwards, and high-difficulty splay training is finished.
Example 4
According to the training process of the embodiment 2-3, when different patients need different degrees of rehabilitation training, only the compression springs 505 with different elastic coefficients need to be replaced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
