Abstract
Joint of lower extremity exerciser, including pedestal are hinged with thigh support frame on pedestal, and thigh support frame is hinged with small leg support, is flexibly connected by push rod between thigh support frame and sliding block, and sliding block is threadedly coupled with horizontal lead screw, and horizontal lead screw is connect with motor；Pulley is movably installed on push rod, flexible strand one end is fixed in small leg support, and the other end is connect with winder after flexible strand bypasses pulley, and winder is connect with motor, and gas spring is connected between thigh support frame and small leg support.The utility model may be implemented thigh, shank linkage, can also realize that shank moves alone by the clutch of different electromagnetic clutch.The utility model is directed to the section art patient that lower limb close, and so that the leg of patient is moved using transmission mechanism, to be performed physical exercise to joint because long-time braking causes to ossify, promotes the recovery of patient limb.
Description
Technical field
The present invention relates to human body passive exercise instruments, more particularly to joint of lower extremity exerciser.
Background technology
Human body limb, articular fracture or injury must have certain braking protection later in operation with sick and wounded, and tissue is
It can healing growth.This just needs planter cast, wears clamping plate, using brace, with turning, wears triangular bandage suspension protection, lie up etc..
This makes the activity of limbs joint reduce, when even stopped, for example fixed with gypsum.Joint after braking is easy
It forms intra-articular adhesion, arthrostenosis, abarticular linked groups' contracture to shorten, this has inevitably resulted in joint deadlock
Directly, limbs, joint is made to lose movable ability.
For example, for the patient that joint of lower extremity ossifys, generally require to be assisted to do joint flexion and extension in bed by other people.
Invention content
To solve problem of the prior art, a kind of joint of lower extremity exerciser is provided, this joint of lower extremity exerciser structure is closed
It manages, is easy to use, effectively the wounded can be assisted to perform physical exercise lower limb.
To achieve the above object, the present invention uses following technical scheme：
Joint of lower extremity exerciser, including pedestal are hinged with thigh support frame on pedestal, and thigh support frame is hinged with small leg support,
It is flexibly connected by push rod between thigh support frame and sliding block, sliding block is threadedly coupled with horizontal lead screw, and horizontal lead screw is connect with motor；
Pulley is movably installed on push rod, flexible strand one end is fixed in small leg support, and flexible strand bypasses the other end and spiral after pulley
Device connects, and winder is connect with motor, and gas spring is connected between thigh support frame and small leg support.
Above-mentioned joint of lower extremity exerciser, lead screw are connect by the first electromagnetic clutch with the first small pulley, the first small band
Wheel is connect with the first big belt wheel installed on motor output shaft by belt；First bevel gear is installed in winder rotation axis, the
One bevel gear engages with second bevel gear, and second bevel gear is connect by the second electromagnetic clutch with the second small pulley, and second is small
Belt wheel is connect with the second big belt wheel installed on motor output shaft by belt.
The present invention may be implemented thigh, shank linkage, can also realize shank by the clutch of different electromagnetic clutch
Independently moving.
First electromagnetic clutch closes, the second electromagnetic clutch detaches, and thigh, shank linkage may be implemented；First electromagnetism
Clutch separates, the second electromagnetic clutch closes, and can individually drive shank movable by winder.
And the effect of gas spring is to push small leg support to hoist reset when winder loosens, flexible strand is loosened.
The present invention is directed to the section art patient that lower limb close, and so that the leg of patient is moved using transmission mechanism, to closing
Section performs physical exercise because long-time braking causes to ossify, and promotes the recovery of patient limb.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the structural schematic diagram of drive part of the present invention.
Fig. 3 is the winder overlooking structure diagram of the present invention.
In figure label for：1 pedestal, 2 thigh support frames, 3 gas springs, 4 small leg supports, 5 flexible strands, 6 winders, 61 second electricity
Magnet clutch, 62 second small pulleys, 63 second big belt wheels, 64 first big belt wheels, 65 first small pulleys, 66 first electromagnetic clutch
Device, 67 first bevel gears, 68 second bevel gears, 7 stepper motors, 8 lead screws, 9 sliding blocks, 10 pulleys, 11 push rods.
Specific implementation mode
With reference to attached drawing, joint of lower extremity exerciser, including pedestal 1 is hinged with thigh support frame 2 on pedestal, and thigh support frame is hinged
There is small leg support 3, be flexibly connected by push rod 11 between thigh support frame and sliding block 9, sliding block 9 is threadedly coupled with horizontal lead screw 8, horizontal
Lead screw is connect with motor；Pulley 10 is movably installed on push rod, 5 one end of flexible strand is fixed in small leg support, flexible strand around
The other end is connect with winder 6 after crossing pulley, and gas spring 3 is connected between thigh support frame and small leg support.
Lead screw is connect by the first electromagnetic clutch 66 with the first small pulley 65, and the first small pulley is exported with stepper motor 7
The first big belt wheel 64 installed on axis is connected by belt；First bevel gear 67, first bevel gear are installed in 6 rotation axis of winder
It is engaged with second bevel gear 68, second bevel gear is connect by the second electromagnetic clutch 61 with the second small pulley 62, the second small band
Wheel is connect with the second big belt wheel 63 installed on motor output shaft by belt.
Thigh, shank linkage：First clutch closes, and the second electromagnetic clutch separation, stepper motor is passed by belt pulley
Dynamic, driving lead screw rotation, the positive and negative rotation of motor makes sliding block move reciprocatingly along lead screw, and hinged push rod drives in sliding block with sliding block
Lower promotion thigh support frame moves reciprocatingly.At this point, since the second electromagnetic clutch detaches, winder does not work, and small leg support can
Under the containing of flexible strand, bending motion also is done under the driving of push rod, to realize the purpose of thigh and shank linkage.For
Human body during exercise comfortable, pedestal carries backrest.
Shank single movement：First clutch closes, and the second electromagnetic clutch separation, stepper motor drives lead screw rotation,
After sliding block is moved to designated position, then first clutch detached, while by the second electromagnetic clutch）It closes, at this time stepping
Motor is driven by first bevel gear and second bevel gear, and driving winder rotation drives the contraction of flexible strand to shorten, or make soft
Property rope loosen it is elongated, when flexible strand is loosened it is elongated when, gas spring pushes small leg support to hoist reset.Pass through the gentle bullet of winder
Spring affects small leg support to move reciprocatingly around thigh support frame, and thigh support frame is not taken exercises due to fixing slide position at this time,
To realize the independently moving of lower leg portion.
