In another better embodiment of the invention, described active elbow joint rehabilitation machines can be according to right-hand man not
It is same to be divided into two kinds of left hand elbow joint rehabilitation machines and right hand elbow joint rehabilitation machines, it is characterised in that：For the right hand elbow joint health
For answering a pager's call, the rocking handle and the pull bar are respectively positioned on the left side lateral surface of the forearm support member, it is possible to use left hand rotates
The rocking handle pulls the pull bar to realize drawing elbow joint to aid in its rehabilitation, the worm gear, the worm screw, described T-shaped
Screw rod, the sliding block and the connecting rod are respectively positioned on the right side lateral surface of the forearm support member, to avoid hindering right arm to move；
The left hand elbow joint rehabilitation machines are in specular with the right hand elbow joint rehabilitation machines.
In another better embodiment of the invention, the straight line draw-off mechanism also includes pulley one and pulley two；Institute
State pulley one and be arranged on being provided with the lateral surface of that side of the pull bar draw-in groove of the forearm support member, the pulley two is erected
Directly it is arranged on the bottom surface platform front end of the forearm support member；Put down the bottom surface that described bracing wire one end is fixed on the forearm support member
Platform front section, the other end bypasses the fixed pulley, the pulley two, the pulley successively again after bypassing the movable pulley
One, it is connected with the pull bar；The forearm sleeve band is fixedly installed on the upper surface of the sliding platform by screw and glue.
It is described rotation draw-off mechanism effect be：When the rocking handle is shaken, the worm screw rotation is driven, the worm screw enters
And driving the worm gear to rotate, the worm gear drives the T-shaped screw rod rotation, sliding block straight line fortune described in the T-shaped screw drive
Dynamic, the sliding straight motion drives the link motion, causes the forearm support member to be revolved relative to the postbrachium support member
Turn, realize the function of rotation drawing elbow joint.It is 1 to use speed reducing ratio:5 worm-and-wheel gear connects the T-shaped screw rod
And the rocking handle, 90 ° of commutations of rotation direction are realized, the torque of the drive mechanism rotation needed for reducing.The T-shaped screw rod is realized
The conversion that the T-shaped screw rod rotary motion moves along a straight line to sliding block.
The effect of the straight line draw-off mechanism is：When the pull bar is pulled back, the bracing wire drives the movable pulley
Travel forward, the movable pulley drives the sliding platform to be travelled forward along the platform slide rail, cause the forearm sleeve band to
Preceding motion, realizes pulling function to the straight line of forearm.The pull bar is stuck in when in the pull bar draw-in groove, is limited described slip and is put down
Motion of the platform relative to the platform slide rail.The pull bar is removed into the buckle position of the pull bar draw-in groove and towards elbow direction
During drawing, there is provided the pulling force for stretching elbow joint, due to being purely manual, user can adjust drawing according to the impression of oneself
Power.When the preferable pulling force of user is reached, pull bar can be moved back to the appropriate buckle position of the pull bar draw-in groove, so that
Keep pulling force.And movable pulley reduces the pulling force provided needed for user.
The effect of the man-machine interface mechanism is to realize being inserted in arm in the postbrachium cuff and the forearm sleeve band.It is logical
Cross the inflatable ball to adjust the size of the forearm sleeve band, realize adapting to the function of different size arm.The forearm sleeve band
The pressure and frictional force of offer can be prevented when straight line drawing function is realized, hand produces slip with cuff.
A kind of active elbow joint rehabilitation machines of the invention, mainly solve existing elbow joint rehabilitation machines high cost and easily cause
The problem of secondary injury.In better embodiment of the invention, the active elbow joint rehabilitation machines include two training work(
Energy：Straight line pulls elbow joint with rotation drawing elbow joint.The active elbow joint rehabilitation machines rely on sliding platform and assembly pulley
Laborsaving pulling elbow joint pulls elbow joint function to realize straight line, and with rocking handle sliding block, the laborsaving rotation forearm of worm and gear
To realize that dynamic rotary pulls elbow joint function.Using the auto-lock function of worm and gear, the active elbow joint of the invention
Rehabilitation machines can after user's rotation forearm to required angle self-locked angle, to maintain the static drawing of a period of time
Power.In better embodiment of the invention, one or two air bag cuff is also equipped with, the arm of different thicknesses can be by sleeve
The aerification function of band realizes the fixation with support member.The present invention replaces the automatically controlled system in existing rehabilitation machines using pure mechanic structure
System, not only reduces cost, and can realize patient's active consciousness control, prevents secondary injury, can be widely used in elbow
In the postoperative rehabilitation of joint.
Compared with prior art, using design of the present invention, following technique effect can be reached：
1st, safe and reliable, using worm and gear self-locking device, whole is not in manually secondary injury.
The 2nd, adjustable pulling force can be provided, accelerate the resume speed of user's elbow, user can according to oneself
Demand adjusts pulling force.
3rd, reliable and stable torque can be provided between 5 ° -140 °, rotary speed can be carried out according to the demand of user
Regulation.
4th, lightweight, portable, can flexible mobile device position, without sticking to fixed position.
5th, due to being non-electrical equipment, its low cost of manufacture uses more economical material benefit.
