As shown in fig. 3, in detail, the force adjusting mechanism 40 further includes a buffer spring 440, and the buffer spring 440 is disposed below the plurality of gravity plates 60.

In addition, the fixed pulley 307 is used for guiding the wire rope 303, so that the friction force borne by the wire rope 303 is reduced on one hand, and the wire rope 303 has a guiding function on the other hand, so that the wire rope 303 is accurately and orderly wound along the first limit guiding groove 308, and the wire rope 303 is prevented from being wound and knotted to influence rehabilitation therapy.
The following description deals with the working principle of the orthopedic rehabilitation device 10 for arm (please refer to fig. 1 to 6 together):
the rehabilitation treatment is carried out, the rehabilitation treatment intensity, namely the number of the required gravity discs 60, needs to be determined firstly; for example, if 3 gravity discs 60 are needed, the movable selection rod 50 sequentially passes through the second through groove 701 of the connecting member 70 and the first through grooves of the 3 gravity discs 60 close to the connecting member 70 from top to bottom; then, a fixing screw is extended from the second connection hole 601 of the third weight plate 60 (counting downward from the upper end near the connecting member 70, the third weight plate 60) into and extended into the first connection hole 501 of the movable selection lever 50; at this time, the movable selection lever 50, the fixing screw and the uppermost 3 gravity plates 60 form a stable whole (referred to as a force acting unit 3), and the force acting unit 3 is connected to a wire 303 through a movable pulley;
it should be noted that, in the actual rehabilitation process, the number of the corresponding gravity plates 60 is appropriately selected according to the physical condition and condition of the rehabilitee; if the intensity of rehabilitation therapy needs to be enhanced, the number of the gravity disks 60 needs to be increased appropriately, and if the intensity of rehabilitation therapy needs to be reduced, the number of the gravity disks 60 needs to be reduced appropriately;
in short, if the number of the gravity disks 60 required to be used for rehabilitation therapy is N (N > < 1), the movable selection rod 50 sequentially passes through the second through groove 701 of the connection piece 70 from top to bottom, then further descends and passes through the first through grooves of the N gravity disks 60 close to the connection piece 70, and then the fixing screws extend into and extend into the first connection holes 501 of the movable selection rod 50 from the second connection holes 601 of the nth gravity disk 60 (counted from the upper end close to the connection piece 70, the nth gravity disk 60); at this time, the fixed screw is locked with the movable selection rod 50, so that the movable selection rod 50, the fixed screw and the uppermost N gravity plates 60 form a stable whole (called as a force action component N); during the rehabilitation treatment process of the rehabilitee (namely, the rehabilitation arm is repeatedly lifted up and down), the force action component N is reciprocated up and down under the action of the wire rope 303;
it should be further noted that, in the process that the force action component N reciprocally ascends and descends under the action of the line 303, the connecting piece 70 and the N gravity discs 60 both stably ascend and descend along the supporting column 201; the support column 201 has a stable guiding function on the force action component N, and the situation that the force action component N swings and shakes during repeated rising and falling under the action of the wire rope 303 to cause unstable arm force of a rehabilitee and finally influence the rehabilitation effect and the use experience of the rehabilitee is avoided;
it should be further noted that the buffer spring 440 is sleeved on the outer wall of the support column 201, and the buffer spring 440 is disposed below the plurality of gravity discs 60; the buffer spring 440 plays a supporting role for the gravity plate 60; when the force action component N moves down to the moment of contacting with the rest of the other gravity discs 60, the gravity of the force action component N is completely pressed on the rest of the other gravity discs 60, and the buffer spring 440 makes the contact between the gravity discs 60 and the gravity discs 60 flexible contact, rather than rigid contact, so that the use experience of the rehabilitee is good;
when the rehabilitee carries out rehabilitation treatment, the rehabilitee only needs to hold the holding piece 304 with a hand and then slowly put down; as the grip 304 is slowly moved downward, the rotating drum 302 is rotated clockwise (as shown in fig. 7) by the arm force; at the moment, one end of the wire rope 303 connected with the holding piece 304 is in an unreeling state; further, the middle portion of the cord 303 is in a wound-up state on the side wound around the thick-cylindrical end 305 (as shown by a1 in fig. 5), and is in an unwound state on the side wound around the thin-cylindrical end 306 (as shown by a2 in fig. 5); since the length of the rope wound by the thick cylinder end 305 is greater than the length of the rope unwound by the thin cylinder end 306, the force acting component N is in a rising state in the process;
when the arm of the rehabilitee is lowered for a certain distance, the arm starts to be lifted up slowly, and the holding piece 304 moves up slowly; as the grip 304 is slowly moved upward, the rotating cylinder 302 is rotated counterclockwise (as shown in fig. 9) by the gravity of the force application member N; at the moment, one end of the wire rope 303 connected with the holding piece 304 is in a rolling state; further, the middle portion of the cord 303 is in an unwinding state on the side wound around the thick-cylindrical end 305 (as shown by a1 in fig. 5), and is in a winding state on the side wound around the thin-cylindrical end 306 (as shown by a2 in fig. 5); because the length of the rope unreeled at the thick cylinder end 305 is greater than that of the rope reeled at the thin cylinder end 306, the force action component N is in a downward moving state in the process; it should be further noted that the distance that the arm is lifted in the process of lifting the arm of the rehabilitee is greater than the distance that the force action component N moves downwards; similarly, the distance for lowering the arm is greater than the distance for moving the force action component N upwards in the process of lowering the arm of the rehabilitee; by the design, the movement amplitude of the force action component N is small under the condition that the movement amplitude of the arm of a rehabilitee is large enough, the phenomenon that the movement amplitude of the force action component N is too large is avoided, and the safety of the orthopedic rehabilitation medical instrument is improved.
The rehabilitation therapy of the muscle and the bone of the arm needs uniform and continuous force application to have better effect. In the rehabilitation process, if the speed of a rehabilitee in the processes of lifting and lowering the arm is too high, the rehabilitation effect is not ideal and the rehabilitation speed is slow. In order to remind the rehabilitee to slowly lift up and slowly lower down in the processes of lifting up and lowering down the arm, so as to ensure that the rehabilitation therapy of the rehabilitee can achieve better effect; the orthopedic rehabilitation medical device 10 applied to the arm further comprises an overspeed warning mechanism 80, which locks the arm force application mechanism when the arm of the rehabilitee is lifted up too fast and put down too fast to warn the rehabilitee to slow down, thereby achieving better rehabilitation treatment effect.
As shown in fig. 4 and 5, in particular, the orthopedic rehabilitation medical device applied to the arm further includes an overspeed warning mechanism 80, the overspeed warning mechanism 80 includes a centrifugal induction component 100, and the centrifugal induction component 100 includes: the centrifugal induction ball bearing comprises a movable lantern ring 110, a supporting and closing swing rod 120 and a centrifugal induction ball 130, wherein the movable lantern ring 110 is sleeved on the rotating connecting rod in a sliding mode, one end of the supporting and closing swing rod 120 is hinged to the movable lantern ring 110, and the other end of the supporting and closing swing rod is connected with the centrifugal induction ball 130.
As shown in fig. 4 and 5, specifically, the overspeed warning mechanism 80 further includes: a driving link 200, a movable locking block 300 and a fixed locking body 400. The movable locking block 300 is slidably sleeved on the rotating connecting rod. One end of the driving connecting rod 200 is hinged with the movable locking block 300, and the other end is connected with the supporting and closing swing rod 120 in a sliding manner. The fixed locking body 400 is connected to the supporting frame. In the embodiment, the fixed locking body 400 is fixedly connected to the supporting frame, and the fixed locking body 400 is provided with a receiving slot 410, and the movable locking block 300 is received in the receiving slot 410 or separated from the receiving slot 410.
As shown in fig. 7, specifically, the receiving groove 410 is provided with a lower locking surface 411 and an upper locking surface 412, the movable locking block 300 is provided with a lower locking mating surface 310 and an upper locking mating surface 320, and the lower locking surface 411 is abutted against or separated from the lower locking mating surface 310; the lift lock surface 412 abuts against or separates from the lift lock engagement surface 320.
As shown in fig. 6, specifically, the overspeed warning mechanism 80 further includes a fixed collar 500, the fixed collar 500 is sleeved on the rotating link, and the prop-close swinging rod 120 is connected with the fixed collar 500 through a connecting spring 600. The cooperation of the fixing collar 500 and the connecting spring 600 provides elastic force for the resetting of the centrifugal sensing ball 130, thereby ensuring that the overspeed warning mechanism 80 can be restored to an unlocked state, and a rehabilitee can continue rehabilitation treatment; moreover, when the overspeed warning mechanism 80 is in the unlocked state, the cooperation of the fixing collar 500 and the connecting spring 600 provides a stable supporting function for the centrifugal sensing ball 130, thereby improving the stability of the centrifugal sensing assembly 100.
As shown in fig. 6, in a preferred embodiment, the number of the supporting and coupling swing rods 120 is two or more, and the two or more supporting and coupling swing rods 120 are distributed in a ring-shaped array around the central axis of the movable collar 110. Accordingly, the number of the driving links 200 is two or more, and the driving links 200 are equally spaced apart from each other around the central axis of the movable locking block 300. And the number of the driving connecting rods 200 corresponds to the number of the supporting and closing swing rods 120 one to one. In this embodiment, the number of the supporting and closing swing rods 120 is two, and the two supporting and closing swing rods 120 are arranged oppositely; the number of the driving links 200 is two, and the two driving links 200 are oppositely disposed. The quantity and distribution of the supporting swing rods 120 and the driving connecting rods 200 are uniform, so that the centrifugal induction assembly 100 is stressed uniformly, and the system stability is high.
The operation of overspeed warning mechanism 80 is further explained below (please refer to fig. 4 to 10):
when the rehabilitee lowers the arm, the rotating link 301 rotates clockwise (as shown in fig. 7); meanwhile, the centrifugal induction component 100 rotates clockwise along with the rotating connecting rod 301; in this process, the centrifugal sensing ball 130 moves away from the central axis of the rotating link 301 under the action of centrifugal force, so as to drive the opening/closing swing link 120 to open with the central axis of the movable sleeve ring 110 as the center, further cause the driving link 200 to open with the central axis of the movable locking block 300 as the center, and the driving link 200 pushes the movable locking block 300 to move along the rotating link 301 toward the direction close to the fixed locking body 400; it should be noted that, the faster the rehabilitation person descends the arm, the faster the rotating link 301 rotates clockwise, the greater the centrifugal force applied to the centrifugal sensing ball 130, so that the centrifugal sensing ball 130 is farther away from the central axis of the rotating link 301, and the closer the movable locking block 300 is to the fixed locking body 400 indirectly;
when the rehabilitation person descends the arm fast enough, the movable locking block 300 enters the containing groove 410 of the fixed locking body 400; when the movable locking block 300 continues to rotate clockwise in the accommodating slot 410 until the lower locking mating surface 310 abuts against the lower locking surface 411, the movable locking block 300 is in a locked state, so that the rotating link 301 is also in a locked state; in this state, when the rotation link 301 stops rotating, the thick-tube end 305 stops rotating, so the rehabilitee cannot pull the holding member 304 to move downwards continuously, thereby reminding the rehabilitee that the arm descending speed is too fast;
if the rehabilitee needs to unlock the overspeed warning mechanism 80, the arm needs to be slowly lifted slightly; this causes the force application member N to move slightly downward and causes the rotating link 301 to rotate slightly counterclockwise (as shown in fig. 8); thereby separating lowering lock mating face 310 from lowering lock face 411; at the same time, the centrifugal force applied to the centrifugal induction ball 130 is reduced because the rotating speed of the movable rotating connecting rod 301 is slowed down; the centrifugal inducing ball 130 is restored to the direction close to the central axis of the rotating link 301 by the elastic restoring force of the connecting spring 600, thereby driving the propping-closing swing rod 120 to be folded by taking the central axis of the movable sleeve ring 110 as the center, and further indirectly driving the driving link 200 to be folded by taking the central axis of the movable locking block 300 as the center; the driving link rod 200 pulls the movable locking block 300 to move along the rotating link rod 301 in a direction away from the fixed locking body 400, so that the movable locking block 300 is smoothly released from the accommodating groove 410 to realize unlocking; after the unlocking is finished, the rehabilitee can continue to slowly lower the arm, so that rehabilitation treatment is continued;
before unlocking, the arm is slightly lifted to separate the lower locking matching surface 310 from the lower locking surface 411, so that the friction force borne by the movable locking block 300 is reduced, and the movable locking block 300 is ensured to be smoothly separated from the accommodating groove 410; assuming that the arm is not lifted up slightly before unlocking, the rotation link 301 does not rotate counterclockwise slightly (as shown in fig. 7), so that the lowering lock fitting surface 310 still tightly abuts against the lowering lock surface 411; in such a case, the driving link 200 cannot be retracted, so that the propping oscillating bar 120 cannot be retracted, and the centrifugal sensing ball 130 cannot be reset, i.e. the overspeed warning mechanism 80 is still in a locked state;
similarly, when the rehabilitee lifts the arm, the rotating link 301 rotates counterclockwise (as shown in fig. 9); meanwhile, the centrifugal induction component 100 rotates counterclockwise along with the rotating connecting rod 301; in this process, the centrifugal sensing ball 130 moves away from the central axis of the rotating link 301 under the action of centrifugal force, so as to drive the opening/closing swing link 120 to open with the central axis of the movable sleeve ring 110 as the center, so as to open the driving link 200 with the central axis of the movable locking block 300 as the center, and the driving link 200 pushes the movable locking block 300 to move towards the direction close to the fixed locking body 400 along the rotating link; it should be noted that, the faster the rehabilitation person descends the arm, the faster the rotating link 301 rotates counterclockwise, the greater the centrifugal force applied to the centrifugal sensing ball 130, so that the centrifugal sensing ball 130 is farther away from the central axis of the rotating link 301, and the closer the movable locking block 300 is to the fixed locking body 400 indirectly;
when the arm of the rehabilitee is lifted fast enough, the movable locking block 300 enters the receiving slot 410 of the fixed locking body 400; when the movable locking block 300 continues to rotate counterclockwise in the receiving slot 410 until the lifting locking mating surface 320 abuts against the lifting locking surface 412, the movable locking block 300 is in a locked state, so that the rotating link 301 is also in a locked state; at this time, the force action component N does not move downwards any more, and the arm of the rehabilitee does not apply force to the force action component N any more; therefore, the arms of the rehabilitee can be lifted easily, and the rehabilitee is reminded that the lifting speed of the arms is too high;
if the rehabilitee needs to unlock the overspeed warning mechanism 80, the arm is slowly and slightly lowered; this causes the force application member N to move slightly upward and the rotating link 301 to rotate slightly clockwise (as viewed in fig. 10); thereby separating the raised locking engagement surface 320 from the raised locking surface 412; at the same time, the centrifugal force applied to the centrifugal induction ball 130 is reduced because the rotating speed of the movable rotating connecting rod 301 is slowed down; the centrifugal sensing ball 130 is reset towards the direction close to the central axis of the rotating link rod 301 under the pulling force of the connecting spring 600, so as to drive the propping oscillating bar 120 to fold with the central axis of the movable lantern ring 110 as the center, further indirectly drive the driving link rod 200 to fold with the central axis of the movable locking block 300 as the center, and the driving link rod 200 pulls the movable locking block 300 to move towards the direction far away from the fixed locking body 400 along the rotating link rod 301, further enabling the movable locking block 300 to smoothly release from the containing groove 410, and realizing unlocking; after the unlocking is finished, the rehabilitee can continuously and slowly lift the arm so as to continue rehabilitation treatment;
similarly, before unlocking, the arm is slightly lowered to separate the raised locking mating surface 320 from the raised locking surface 412, so as to reduce the friction force applied to the movable locking block 300, thereby ensuring that the movable locking block 300 is smoothly released from the receiving groove 410.
The orthopedic rehabilitation medical device 10 applied to the arm of the invention can be used for warning radial locking when the lifting and lowering speed of the arm of a rehabilitee is too high through the overspeed warning mechanism 80, so as to ensure that the rehabilitee can lift and lower the arm according to the required speed, thereby achieving better rehabilitation treatment effect.
