The utility model discloses can also form new implementation mode with embodiment 1 with at least one in embodiment 2, 3, 4 the technical characterstic.

The working principle is as follows: the sitting and lying frame is used for lying when the patient carries out rehabilitation training. When the patient carries out shank rehabilitation training, the running-board is stepped on to the foot, promotes the running-board hard and can drive the bar slide and slide along bar shape slide groove length direction, because the setting of spring can promote the bar slide withdrawal after patient's shank unloads power to realize that the running-board resets, reciprocal so in proper order realizes that patient's shank is taken exercise. When the patient carries out shank rehabilitation training, can realize the regulation and control of bar slide conflict dynamics. The manual frame of manual rotation drives the lead screw and rotates, and the rotation of lead screw makes the traction seat along lead screw length direction reciprocating motion through lead screw transmission assembly, and the motion of traction seat can drive the flexible piece motion through the tensioning haulage rope. When the movement of the tensioning traction rope enables the telescopic block to move close to the fixed connection end of the spring, the spring is in a compressed state; when the movement of tensioning haulage rope makes the flexible piece correspond the fixed connection end position of spring and when the opposite side end direction motion, the spring can promote flexible piece motion. Artificial regulation and control can realize the regulation and control of flexible piece position, when flexible piece is close to spring fixed connection end and reachs a definite position, this spring compression of should locating, this spring can't cooperate the bar slide back and forth movement, realize the regulation and control of the spring quantity that can work in the bar spout, the unable work of partial spring compression in the bar spout this moment, partial spring can work, thereby realize the regulation and control of bar slide conflict dynamics, the patient can select the quantity of the spring that can work according to self condition, thereby realize the regulation and control of running-board conflict dynamics, realize effectual rehabilitation training. When the hand rehabilitation training mechanism is not used, the positioning hooks are hung in the positioning hanging grooves to realize position support of the power rod, at the moment, the first lifting hook is hung in the first positioning hanging ring, the second lifting hook is hung in the second positioning hanging ring to realize the stability of the positions of the first lifting hook and the second lifting hook. When the patient selects the pull-down rehabilitation training, first promotion couple withdraws from on first location link, first promotion couple is hung again in the first promotion link, the balancing weight movable sleeve is outside the traction frame, and place in the horizontal support frame upper end, the hoisting frame rotates and makes the lifting bar corresponding with rectangle bayonet socket position, the lifting seat moves down and can drive the hoisting frame, the lifting bar moves down, the lifting bar runs through the rectangle bayonet socket and inserts the cavity inslot, rotate the swing joint between hoisting frame and the traction frame again and realize. When the patient selects to lift the rehabilitation training, the first lifting hook is hung in the first positioning hanging ring again, the second lifting hook is withdrawn from the second positioning hanging ring, and the second lifting hook is hung in the second lifting hanging ring again. The lifting hook is connected with the lifting hanging ring to realize the use of the hand rehabilitation training mechanism, and the lifting hook is connected with the positioning hanging ring to realize the stability of the position of the lifting hook when the hand rehabilitation training is not used. The annular positioning slide block is movably arranged in the positioning chute and can slide along the length direction of the positioning chute, so that the directional sliding of the position of the power rod is realized. When equipment used, the power rod was held to patient's hand, rotated the certain angle of power rod, thereby can make the location couple fix a position and hang and withdraw from in the groove, but power rod up-and-down motion this moment. When equipment did not use, patient's hand rotated the certain angle of power pole, made location couple card go into the location and hung the groove, realized the firm of power pole position.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
