The orientation or positional relationship of instruction is positional relationship based on the figure, is merely for convenience of description the utility model and simplification
Description, rather than the device or element of indication or suggestion meaning must have a particular orientation, constructed and grasped with specific orientation
Make, therefore should not be understood as limiting the present invention.In addition, term " first ", " second ", " third " are only used for description mesh
, it is not understood to indicate or imply relative importance.
As shown in Fig. 1 to 2, the transmission mechanism of four limbs linkage device for rehabilitation is arranged for realizing four limbs linkage device for rehabilitation two
Transmission between the first of side foot-operated 2.1 and second foot-operated 2.2.
Transmission mechanism includes the transmission shaft 3 for being mounted on four limbs linkage device for rehabilitation and being arranged in rack 1.
Transmission shaft 3 divides for the first transmission shaft 3.1 and second driving shaft 3.2.
First transmission shaft 3.1 is connected with first foot-operated 2.1, enables first foot-operated 2.1 to turn with the first transmission shaft 3.1
It moves and moves；Second driving shaft 3.2 is connected with second foot-operated 2.2, enables second to ride 2.2 with second driving shaft 3.2
It rotates and moves.
It is connected between first transmission shaft 3.1 and second driving shaft 3.2 by cross universal coupling 4, makes the first transmission shaft
It is driven between 3.1 and second driving shaft 3.2 by cross universal coupling 4.
Cross universal coupling 4 makes the reason of the first transmission shaft 3.1 and second driving shaft 3.2 are because of processing or assembly, place
In non-coaxial situation, transmission that also can be smooth, to keep the rotation of transmission shaft more smooth, rotary resistance is balanced, from
And allow user's pushes pedals when, the constant resisting force experienced, to smoothly have an effect when enabling to scrunch, improve scrunch it is comfortable
Property, guarantee rehabilitation training effect.
In order to make two it is foot-operated can synchronous backward movement so that both legs be enable alternately to scrunch make stepping movement more
Continuous and smooth, the first transmission shaft 3.1 is installed with the first attachment base 5.1, and second driving shaft 3.2 is installed with the second attachment base 5.2.
First attachment base 5.1 is connected by first connecting rod 6.1 with first foot-operated 2.1, and 6.1 both ends of first connecting rod pass through hinge
It connects connected.Second attachment base 5.2 is connected by second connecting rod 6.2 with second foot-operated 2.2, and 6.2 both ends of second connecting rod pass through hinge
It connects connected.
First attachment base 5.1 is parallel to each other with the second attachment base 5.2, when the second attachment base 5.2 is located at second driving shaft 3.2
When rear side, the first attachment base 5.1 is located at the front side of the first transmission shaft 3.1.
First transmission shaft 3.1 and second driving shaft 3.2 are under the transmission of cross universal coupling 4, synchronous rotary.First connects
Joint chair 5.1 and the second attachment base 5.2 are also with corresponding transmission shaft synchronous rotary.
Angle between first attachment base 5.1 and the second attachment base 5.2 is 180 degree, when the first attachment base 5.1 from front to back
When swing, the second attachment base 5.2 is swung from back to front, so that second connects when the first attachment base 5.1 being made to pull first connecting rod 6.1
Joint chair 5.2 pushes second connecting rod 6.2, and then makes first foot-operated 2.1 to move backward under the pulling of first connecting rod 6.1, and second
Foot-operated 2.2 move forward under the promotion of second connecting rod 6.2, realize that two foot-operated synchronous backwards are mobile, allow one foot of user
When trampling first foot-operated 2.1 forward, by the transmission of transmission shaft, second foot-operated 2.1 can be driven to move backward, by user's
Another foot lifts backward, and when user trains, two feet can be scrunched alternately, and transmission shaft continues to rotate in same direction, and two
It is a it is foot-operated can continuously run, make user leg whole always in the state scrunched of having an effect, enable to scrunch training continuous
And smoothly carry out, trained effect is trampled in guarantee
Due to needing to carry out the user of rehabilitation training, constitution is all more weak, in order to allow user more easily to make
With device for rehabilitation, the first swing rod 7.1 and the first strut 8.1 are installed between first foot-operated 2.1 and rack 1, second rides 2.2 and machine
Second swing rod 7.2 and the second strut 8.2 are installed between frame 1.
The both ends of first swing rod 7.1 are hinged with first foot-operated 2.1 and rack 1 respectively, the both ends of the first strut 8.1 respectively with
First foot-operated 2.1 and rack 1 it is hinged, make the first foot-operated 2.1, first swing rod 7.1, rack 1, the first strut 8.1 composition double leval jib
Structure.
The both ends of second swing rod 7.2 are hinged with second foot-operated 2.2 and rack 1 respectively, the both ends of the second strut 8.2 respectively with
Second foot-operated 2.2 and rack 1 it is hinged, make the second foot-operated 2.2, second swing rod 7.2, rack 1, the second strut 8.2 composition double leval jib
Structure.
When transmission shaft drives swing rod to swing by connecting rod, foot-operated and strut is also swung therewith.Since strut is located at swing rod
Rear side, the length of swing rod is less than strut, therefore the pendulum radius of swing rod is less than strut, when swing rod and strut swing aside,
Compared to the top of strut, height and position is lower on the top of swing rod, and difference in height is increasing, to make and swing rod and strut top
End is connected foot-operated, gradually swings forward, makes foot-operated upper surface gradually towards front side, so that user can be with a kind of leg
The state of almost horizontal is scrunched, and is trained so that user can be sitting on the lower seat of height and position,
Need not be laborious when being moved on device for rehabilitation, convenient for the upper machine training of weak user.
