Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Embodiment 1
A kind of clutch of wheelchair is equipped with crank rotor plate 9, first as shown in Figure 1 to Figure 3 on the axle 14 of wheel
Clutch discs 10 and the second clutch discs 12, first clutch discs 10, the second clutch discs 12 are matching piece, first clutch discs 10
It fixes, is connected between the second clutch discs 12 and axle 14 for feather key, the second clutch discs 12 can be in axle 14 with 9 phase of crank rotor plate
On slide axially and cannot be rotated relative to axle 14, between first clutch discs 10, the second clutch discs 12 be equipped with spring 11, institute
The clutch stated further includes plectrum 13, and for the second clutch discs 12 between spring 11, plectrum 13, it is rectangular that plectrum 13 is equipped with one
Shape through-hole, axle 14 pass through the through-hole, and plectrum 13 will not interfere with the rotation of axle 14.Plectrum rotating member is additionally provided on vehicle frame
16,16 pin connection of plectrum rotating member is on vehicle frame, and the plectrum rotating member 16 can be around this pin rotation, and the plectrum 13, which is fixed on, to be dialled
The end of piece rotating member 16, if rotation plectrum rotating member 16, plectrum 13 also rotate.
It as shown in Figure 4, Figure 5, further include double rocker mechanism and double rocker mechanism mounting plate 19, the double rocker mechanism packet
Drive crank switch 18, driven rocking bar 21 and Isolating Switch connecting rod 20 are included, plectrum rotation is connected on the driven rocking bar 21
Line 17,17 other end of plectrum rotational line are connected with plectrum rotating member 16.
In the present embodiment, bearing is installed between crank rotor plate 9 and axle 14.
In the present embodiment, block 37 is equipped on the inside of the Isolating Switch connecting rod 20.
In the present embodiment, rotational line fixed frame 38, the rotational line fixed frame are additionally provided on double rocker mechanism mounting plate 19
The 38 corresponding positions hole Shang You, pass through for the plectrum rotational line 17.
The working principle of clutch is as follows:
As shown in figure 4, the drive crank switch 18 is opened with the clutch when not stirring the drive crank switch 18
Connection bar 20 has angle, and the driven rocking bar 21 described at this time is to the plectrum rotational line 17 without pulling force, and plectrum rotational line 17 is to plectrum
Rotating member 16 is also without pulling force, and the plectrum 13 is to 12 no pressure of the second clutch discs, first clutch discs 10 and described the
Two clutch discs 12 separate under the spring-force driven dual of the spring 11；Meanwhile because the crank rotor plate 9 and the axle 14 it
Between bearing is installed, so, the crank rotor plate 9, first clutch discs 10 not with the axle 14 rotate.
As shown in figure 5, being driven by Isolating Switch connecting rod 20 described when stirring drive crank switch 18 and rotating counterclockwise
Driven rocking bar 21 is swung, and tenses the plectrum rotational line 17, rotates the plectrum rotating member 16 around pin, while the plectrum 13
The plectrum rotating member 16 is followed to rotate together, the plectrum 13 compresses second clutch discs 12, second clutch discs 12
It moves in the axial direction, overcomes the spring-force driven dual of the spring 11, make second clutch discs 12 and first clutch discs
The cooperation of 10 end faces, drives first clutch discs 10 to rotate together with second clutch discs 12, makes the crank rotor plate 9 with institute
Axle 14 is stated to rotate together；Because there is the block 37, the rotation of the drive crank switch 18 is made to have certain limit
System, the drive crank switch 18 is overlapped with the center line of the Isolating Switch connecting rod 20 at this time, at a horizontal line, in dead
Point position will not drive the drive crank switch 18 to reverse even if there is the spring 11.
The drive crank switch 18 is rotated clockwise manually, can be resetted.
When needing to carry out lower limb progress reconditioning, the drive crank switch 18 is rotated counterclockwise, the crank
Turntable 9 rotates, and transfers power to the lower limb rehabilitation rocking bar 3 by crank connecting link 5, the lower limb rehabilitation rocking bar 3 is driven to do
Reciprocating swing, to carry out recovering aid to user's lower limb.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
