Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Following reality
Example is applied for illustrating the present invention, but is not limited to the scope of the present invention.
As shown in Figures 1 to 5, The embodiment provides a kind of rehabilitation training of upper limbs machine, it includes frame 1, sets
Motor 2, the output gear 3 being connected on the motor 2 in the frame 1 and it is meshed with the output gear 3
Travelling gear 4, the center of the travelling gear 4 is provided with power transmission shaft 5, and the power transmission shaft 5 is installed on pedestal 6, the power transmission shaft 5
A crank 7 for radially extending respectively is installed at two ends, and the other end of the crank 7 has extended perpendicularly outward rotating shaft 8, the machine
Two outer side edges of frame 1 are outward extended with support shaft 9 positioned at the rear of rotating shaft 8, and the rotating shaft 8 and support shaft 9 are located at same level
On.
The rehabilitation training of upper limbs machine also include one before arm support 10, the middle part of the front arm support 10 is rotationally connected with described turning
On axle 8, the rear portion of the front arm support 10 is provided with bar-shaped trough 11, the support shaft 9 be installed in the bar-shaped trough 11 and with it is described
Bar-shaped trough 11 is formed and is slidably connected;Therefore after electric motor starting, drive axis are driven by output gear, travelling gear, is passed
Moving axis further drives rotating shaft to move in a circle by axle center of power transmission shaft, because the bar-shaped trough at front arm support rear is limited in support shaft
It is interior, therefore front arm support will swing in fan shape, because the circular motion of rotating shaft causes support shaft back and forth to slide in bar-shaped trough
It is dynamic.
The front top of the front arm support 10 is provided with hole slot 12, the hole slot 12 and is provided with buffer bar 13, the buffering
Bar 13 puts in and have on the side wall of hole slot 12 boss 14, and two springs 1 are respectively fitted over the both sides of 13 boss of buffer bar 14,
The end of the hole slot 12 is provided with groove lid 16 for two springs 1 to be enclosed in hole slot 12;The outer end of the buffer bar 13
It is articulated with the middle part of a rotating bar and rotating bar is divided into into rotation upper boom 17 and lower beam 18 is rotated, the outside of the front arm support 10 is also
A hinged seat 19 is provided with, the hinged seat 19 is hinged by a hinge bar 20 with the outer end of the rotation lower beam 18;It is described
Rotate upper boom 17 and be provided with chute 21 near end, the chute 21 is interior to be provided with guide pillar 22, and on the guide pillar 22 bullet is provided with
Spring 2 23, the medium position for rotating upper boom 17 is provided with a screwed hole 24.
Also include a slide plate 25 and linking arm 26, the top of the slide plate 25 is respectively provided on two sides with a runner 27, the slide plate
25 two bottom sides are respectively equipped with a slide block 28, and the slide block 28 is provided with a through hole 29, and the slide block 28 is slidably mounted on the cunning
In groove 21, the through hole 29 of the slide block 28 is arranged on the guide pillar 22 so that the side wall of the slide block 28 is resisted against the spring
2 23;The linking arm 26 is provided with a connecting hole (not shown), the connecting hole and the screwed hole 24 for rotating upper boom 17
It is coaxially disposed, a screw 30 is screwed together on the screwed hole 24 through after the connecting hole and makes the linking arm 26 relatively described
Rotate upper boom 17 freely to rotate, concave-arc part 31 is provided with the two side of the linking arm 26, the runner 27 on the slide plate 25 is embedding
Together in the concave-arc part 31.
The top for rotating upper boom 17 is provided with armrest part 32.
The motor 2 is motor.
When using, forearm is placed or is fixed on front arm support, forearm can be with fan-shaped rotation of front arm support with its turn
It is dynamic;The handss of people hold armrest part, and due to the design using buffer bar, rotating bar, hinge bar and hinged seat, wrist can be with rotating bar
Middle part is axle center, and along arm place, rectilinear direction freely swings back and forth, due to the design of two springs one and buffer bar so that handss
Wrist is effectively buffered in swing process;When wrist swings to two side directions of arm, armrest part passes through
Linking arm conducts to power, and the concave-arc part on linking arm is applied a force on the runner of slide plate, because slide plate is limited in cunning again
In groove, therefore linking arm drives slide plate to move along chute, and then compresses the spring two in chute so that linking arm can only do limited
Angle swings, and the bigger resistance of pendulum angle is bigger, therefore the wrist of people not only can swing, swing,
And the amplitude of swinging can be limited, in swing, there is provided the buffering to wrist, the buffering effect of the wrist is whole
It is likewise supplied with when upper limb is driven by motor.
The present invention is rotated by motor and drives forearm frame to do fan-shaped rotation, so as to drive the forearm being fixed thereon to do sector
Rotate, the rotation of forearm will certainly drive postbrachium to move together, so as to reach the purpose for tempering arm, meanwhile, wrist can be along front
Arm place rectilinear direction swings back and forth, and the motion of the design of buffer bar to wrist serves cushioning effect, protects wrist not injured
Evil, while wrist can also do the swing of limited amplitude to the both sides direction of arm, so as to reach the purpose of rehabilitation wrist, while and
Can be prevented effectively from wrist because arbitrarily rotate it is excessive cause secondary injury.
Certainly, the above is only the concrete application example of the present invention, protection scope of the present invention is not limited in any way.Remove
Outside above-described embodiment, the present invention can also have other embodiment.The technical side that all employing equivalents or equivalent transformation are formed
Case, all falls within scope of the present invention.
