The bevel gear five of described double linked wheel 2 11 lower ends is meshed with the bevel gear six of double linked wheel 5 23 left ends,Double linked wheel 5 23 kinks are on fixed axis 4 24, and formation is rotationally connected with it, described fixed axis 4 24Be fixed on right side and connect on pivoted arm 26 right flanks, the left surface that right side connects pivoted arm 26 has semicircle orifice, the right sideOn the right flank of side guide 28, also have same semicircle orifice, rotating shaft one 8 lower end external parts are connected and turn with right sideThe semicircle orifice laminating of the semicircle orifice of arm 26 left surfaces and right side pressing plate 28 right flanks, by tightening four connectionsBolt 27, makes right side connect pivoted arm 26 and is fixed in rotating shaft 1.
The right-hand member belt wheel five-way of described duplicate gear 5 23 is crossed and is with 3 25 to form band transmission with belt wheel 6 30,Regulating wheel 3 29 is at the outside tension band 3 25 with 3 25, and described belt wheel six is fixed in rotating shaft 5 31,Rotating shaft 5 31 is connected pivoted arm 26 formation and is rotationally connected with right side with bearing 37 by bearing block, the large arm in right side connectsThe circle hole sleeve of extension bar 35 1 sides is at the left side of rotating shaft 5 31 overhanging end, and the circular hole of the large arm connecting rod 35 in right side arrivesEnd has otch, 36 large arm connecting rod 35 incision sites in right side is narrowed be clamped in by tighting a boltIn rotating shaft 5 31, large arm connecting rod 1 is square outline, on the large arm connecting rod 35 in right side, position is housedAdjust slide block 1, position is adjusted on slide block 1 and is fixed with large arm holder 1, the two ends of large arm holder 1Bandage 34 is installed on slotted hole, and described position is adjusted slide block Yi32 center and is had square hole, enable alongThe large arm connecting rod 35 in right side, right side slides, and the lower end that slide block 1 is adjusted in position has otch, by tighteningBolt 38 narrows position adjustment slide block one 32 lower end otch, makes position adjust slide block 1 and is fixed on right sideOn large arm connecting rod 35.
On described bearing block installing plate 7, be fixed with tensioning fixed mount 42, bearing block installing plate 7 centre positionsDownside has square notch, tensioning fixed mount 42 " U " shape, and the parallel edges horizontal positioned of its " U " shape,Fasten that frame 42 base inner surfaces paste and at the trailing flank of bearing block installing plate 7, and its " U " shape twoParallel edges is fitted in respectively the upper side of bearing block installing plate 7 and the upper side of square indentation, there. Tensioning is fixedOn upper side edge in 42 liang of parallel edges of frame, be fixed with sliding sleeve 2 43, lower side is fixed with sliding sleeve 3 39, sliding sleeve2 43 have square hole, and square slider 1 forms and is slidably connected with sliding sleeve 2 43, square slider 40One side is fixed with axle 6 41, and regulating wheel one 19 kinks, on axle 6 41, are rotationally connected with its formation.
The other end of described square slider 40 is made screw rod, is combined with nut 44 at its screw portion, passes throughScrew nut tension band 1.
Described regulating wheel 2 14 has identical tension structure with regulating wheel 1.
Described regulating wheel 3 29 has identical tension structure with regulating wheel 1, unique different be regulating wheel3 29 sliding sleeve 5 45 is directly fixed on right side and connects on pivoted arm 26.
Left side connects pivoted arm 46 and is fixed on rotating shaft 3 17 lower ends, left side connect the left surface of pivoted arm 46 be equipped withRight side is about the double linked wheel 6 47 of patient's symmetry, double linked wheel 4 15 lower end bevel gears seven and double linked wheel 6 47 right sidesThe bevel gear eight of end engages, and left side connects pivoted arm 46 to the large arm bondage in patient left side, guiding mechanism and right side and connectsLarge arm bondage, guiding mechanism have the symmetrical structure about patient to patient right side to switch through arm 26.
In the autonomous recovery training appliance for recovery of this health shoulder joint, all band transmissions and gear-driven gearratio are 1.
Patient is sitting on seat 2, adjusts the upper-lower position of sliding sleeve 5, then adjusts whole shoulder rehabilitation fortuneThe height of actuation mechanism makes patient more comfortable, and the large arm level in patient right side is placed in the large arm holder 1 on right side,The large arm level in left side is placed in the large arm holder two in left side, and slide block 1 is adjusted on right side, and left side is adjusted slide block two and madePatient is more comfortable. If the large arm energy active movement of patient right side, when the large arm in right side swings up and down, drives rightThe large arm connecting rod 1 of side swings up and down centered by rotating shaft 5 31, and rotating shaft 5 31 is rotated, belt wheel 6 30Rotate, by being with 3 25 to drive double linked wheel 5 23 to rotate, drive double linked wheel 2 11 to rotate, double linked wheel 3 12Rotate, by being with 2 13 to drive double linked wheel 4 15 to rotate, by middle transmission mechanism, drive left side largeArm holder two is synchronizeed and is swung up and down with the large arm holder one in right side.
When the large arm in patient right side swings, right side connects pivoted arm 26 rotates centered by rotating shaft 1, rotating shaftOne 8 rotate, and gear 1 rotates, and double linked wheel 1 rotates, by being with one 20 band movable belt pulleys 2 18 to rotate,Rotating shaft 3 17, left side is switched through arm 46 and is connected pivoted arm rightabout with right side and rotates, and realizes patient two armsAbduction or containing simultaneously. The large arm in patient right side swings simultaneously, and the large arm in right side does not swing up and down, duplexTake turns 5 23 and can not rotate, rotate with rotating shaft 1 because right side connects pivoted arm 26, double linked wheel 5 23 forces twoConnection wheel 2 11 is synchronizeed rotation with rotating shaft 1, double linked wheel 3 12 is by being with 2 13 drive double linked wheels 4 15 to turnMoving, and now another road drive shaft 1 rotates, and drives double linked wheel 1 to rotate, double linked wheel 1 is logicalCross and be with one 20 band movable belt pulleys 2 18 to rotate, rotating shaft 3 17 is rotated, rotating shaft 3 17 with duplex 4 15 withDirection, rotate with speed, the large arm luffing mechanism in left side can not move, on the large arm in patient left side is not understoodLower swing.
The large arm in patient right side swings up and down while also swinging simultaneously, is that the large arm in right side swings up and down with left and right and putsThe resultant motion of moving two kinds of independently movings, the large arm in left side does swinging up and down and the right side of synchronizeing with the large arm in right side equallyThe rehabilitation exercise that left swing is moving.
The large arm active movement in patient left side, transmission mechanism moving line is contrary, makes equally the large arm in right side do and a left sideThe large arm of side is about the rehabilitation exercise of patient's symmetry.
