along with the upward swinging of the bed plate 2 along the rotating shaft 3 at the rear side, the bed plate 2 drives the transmission belt 30 to tighten through the transmission shaft 24 at the front side, the transmission belt 30 drives the tension pulley 29 to swing backwards, the tension pulley 29 drives the connecting rod to swing backwards and extrude the torsion spring, the bed plate 2 drives the rotating shaft 3 at the front side to swing upwards and swing out of the U-shaped frame 16 at the corresponding side, the bed plate 2 simultaneously pushes a patient to swing backwards, after the incomplete gear 31 is disengaged from the auxiliary gear 35, the auxiliary gear 35 stops rotating with the belt wheel shaft, due to the unidirectional self-locking property of the worm mechanism, the main worm wheel 18 and the auxiliary worm wheel 19 stop rotating, the column 7 drives the plug-in column 8 to move to the upper end of the column 7, the position of the inverted T-shaped block 5 is limited, the position of the semicircular ring 17 is limited, the patient swings to the left side lying position at the moment, and the tension pulley 29 swings backwards to the limit position;
as the incomplete gear 31 continues to rotate, the incomplete gear 31 is meshed with the main gear 32 and drives the main gear 32 to rotate anticlockwise, the main gear 32 drives the main bevel gear 33 to rotate anticlockwise through the support shaft, the main bevel gear 33 drives the auxiliary bevel gear 34 to rotate anticlockwise, the auxiliary bevel gear 34 drives the rotary post 28 to rotate anticlockwise, the rotary post 28 drives the transmission shaft 24 on the front side to rotate anticlockwise through the transmission belt 30, the transmission shaft 24 drives the conveyor belt 25 to rotate anticlockwise, the conveyor belt 25 drives the push rod 26 on the right side to rotate along the conveyor belt 25, the push rod 26 on the right side pushes the slide rod 22 on the corresponding side to slide forwards, and the slide rod 22 drives the two slide barrels 10 on the corresponding side to slide relatively through the pull belt 23;
along with the relative sliding of the two right sliding cylinders 10, the two right sliding cylinders 10 drive the back patting blocks 12 on the corresponding sides to slide relatively, the back patting blocks 12 drive the guide posts 15 on the corresponding sides to slide downwards along the chutes 13, the guide posts 15 drive the back patting blocks 12 to slide downwards and extrude the compression springs 11, when the guide posts 15 move to the vertical slots 14, the back patting blocks 12 pop upwards under the action of the compression springs 11, due to the inertia of the upward movement of the back patting blocks 12, the back patting blocks 12 extend upwards out of the chutes 9 and patt the back of a patient through the elastic cloth, meanwhile, the back patting blocks 12 drive the guide posts 15 on the corresponding sides to slide upwards along the chutes 13, when the guide posts 15 move to the upper ends of the vertical slots 14, the back patting blocks 12 perform back patting on the patient once, and simultaneously along with the relative movement of the two back patting blocks 12, the two back patting blocks 12 drive the guide posts 15 on the corresponding sides to continuously slide into the adjacent chutes 13 and are inserted into the chutes 13, at this time, the guide post 15 drives the back patting block 12 to move downwards under the action of the chute 13 and slide upwards again when moving to the adjacent vertical groove 14, and through the above steps, the back of the patient is patted, in conclusion, through the guide of the chute 13 and the vertical groove 14, in the process that the two back patting blocks 12 slide relatively, the back patting block 12 slides up and down, and the back of the patient is patted from two sides to the middle;
when the conveyor belt 25 pushes the sliding rod 22 to move to the left end of the rectangular groove 21 through the rightmost push rod 26, the push rod 26 moves to the left end of the conveyor belt 25, along with the rotation of the conveyor belt 25, the push rod 26 moves downwards, at the moment, the push rod 26 is separated from the sliding rod 22, the right sliding cylinder 10 moves to a limit position relatively, at the moment, the two sliding cylinders 10 slide back to back under the action of a return spring, and because the other side of the guide post 15 is an inclined plane, along with the back to back sliding of the two sliding cylinders 10, the guide post 15 moves rightwards and is inserted into a pressure groove, when the sliding cylinder 10 returns to an initial position, the racket back block 12 returns to the initial position under the action of the pressure spring 11, at the moment, the support spring pushes the guide post 15 to be inserted into the chute 13 on the corresponding side again, and the right two racket back blocks 12 complete one-time racket back;
as the conveyor belt 25 continues to rotate, the rightmost adjacent pusher bar 26 contacts its respective side slide bar 22, through the steps, the two sliding cylinders 10 are driven to slide relatively, the two sliding cylinders 10 drive the back patting blocks 12 on the corresponding sides to slide relatively, the two back patting blocks 12 perform back patting on the patient under the action of the inclined grooves 13 and the vertical grooves 14, as can be seen from the above, when the rightmost adjacent push rod 26 moves to the leftmost end of the conveyor belt 25, the push rod 26 is disengaged from the slide bar 22 on its corresponding side, the two slide cylinders 10 on the corresponding sides of the slide cylinders are restored to the initial positions under the action of the springs, and in conclusion, the back of the patient is patted from right to left by the plurality of back patting blocks 12 along with the rotation of the conveyor belt 25 through the movement of the plurality of push rods 26 and is restored to the initial positions, after the conveyor belt 25 rotates for a circle, the push rod 26 and the slide rod 22 return to the initial positions, and the back of the patient is patted again along with the rotation of the conveyor belt 25;
when the conveyor belt 25 rotates an integer number of times, the incomplete gear 31 is disengaged from the main gear 32, at this time, the incomplete gear 31 is engaged with the pinion 35, the pinion 35 drives the worm 20 to rotate through the pulley shaft and the wedge belt 36, the worm 20 drives the main worm wheel 18 and the pinion worm wheel 19 to rotate, the main worm wheel 18 drives the semicircular ring 17 to rotate, the pinion worm wheel 19 drives the cylinder 7 to rotate, the cylinder 7 drives the inverted T-shaped block 5 to move downwards through the insert column 8, the bed plate 2 swings downwards along the rotating shaft 3 at the rear side under the action of the gravity of the bed plate 2 and a patient, the torsion spring drives the tension wheel 29 to stretch the transmission belt 30 through the connecting rod, when the bed plate 2 returns to the initial position, the cylinder 7 drives the insert column 8 to move to the lower end of the cylinder 7, at this time, the rotating shaft 3 at the front side is inserted into the U-shaped frame 16 again, at the same time, the semicircular ring 17 at the rear side does not shield the rotating shaft 3 at the corresponding side, and the semicircular ring 17 at the front side shields the rotating shaft 3 at the corresponding side, with the continuous rotation of the worm 20, the auxiliary worm wheel 19 drives the inverted T-shaped block 5 to move upwards through the cylinder 7 and the inserting column 8, meanwhile, the inserting column 8 slides forwards along the waist-shaped groove 6, the bed plate 2 rotates along the rotating shaft 3 at the front side, so that the patient swings to the right side lying position, at the moment, the inserting column 8 moves to the upper end of the cylinder 7 again and moves to the middle of the waist-shaped groove 6, the incomplete gear 31 is disengaged from the auxiliary gear 35 and is engaged with the main gear 32 again, and the back patting block 12 is driven to perform back patting when keeping the right side lying position of the patient through the steps;
when the conveyor belt 25 rotates for an integer number of times again, the incomplete gear 31 is disengaged from the main gear 32, and the bed plate 2 swings to the initial position through the above steps, the main worm gear 18 drives the semicircular ring 17 to return to the initial position, the cylinder 7 drives the plug-in post 8 to move to the initial position, the motor is turned off, and the back of the patient is patted.
