Description
Technical field
The present invention has joint rehabilitation device that is fixing or restriction joint motion angle about a kind of.
Background technology
Press, commonly use joint rehabilitation device as just as Suo Shi case before No. 098219410th, TaiWan, China " setting device of knee joint fixer ", No. 097220383 " joint support frame adjustment device ", No. 096210485 " locating structure of knee joint fixer " etc. patent, but, before these patents, the structure of case is quite complicated, cause tooling cost effectively to reduce, operate also very convenient.
The present inventor is because above take off the shortcoming of case before patent, and through constantly conceiving, wound is ground, and is develop the present invention.
Summary of the invention
The present invention provides a kind of and has joint rehabilitation device that is fixing or restriction joint motion angle, and its structure is simple and convenient for control.
For reaching above-mentioned purpose, the solution of the present invention is:
A kind of joint rehabilitation device, includes:
One first frame body, it defines a spacing groove with the first side plate and the 2nd side plate, and in this spacing groove, cross-over connection has axis and the first axle respectively, and this first and second side plate is separately provided with an angular setting hole group, in order to provide a retaining bolt clutch;
One the 2nd frame body, it is provided with the ratchet plugged together in spacing groove, and this ratchet center has the middle hole wearing pivot for axis, and ratchet periphery is equipped with outer toothed portion;
One control lever, it plugs together in spacing groove, and is provided with the latch of energy mesh ratchet gear outer toothed portion in one end edge, then forms one as another end edge and for the pulling part of force, more can be provided with the first hole wearing pivot for the first axle between latch and pulling part;
One elastomeric component, it is installed in spacing groove, makes it to provide default elastic force to give control lever, makes latch have the gesture of mesh ratchet gear outer toothed portion at any time, and controlling the 2nd frame body according to this can be only locating towards retaining bolt unidirectional rotation of fulcrum taking axis.
Be provided with one in the first frame body further and buckle block, until pulling part force latch be in depart from ratchet position time, this button block can switch one support control lever be positioned this position so that the 2nd frame physical efficiency taking axis be fulcrum carry out backlash.
Further, buckle structure be provided with in control lever, the first side plate further mate mutually assembly hole, guide groove, and lead bolt with one and run through guide groove and be consolidated in assembly hole, control lever must be driven lead bolt and move along guide groove, then being pivoted button block with a tip part outside first side plate, this button block then has a button groove, when pulling part forces latch to be in disengaging ratchet outer toothed portion position, the button groove of this button block then can enter lead bolt around the card that tip part swings, and the support control lever in order to switching is positioned this position.
Further, separately it is provided with, in the first side plate, the braking tip that can limit button block deflection.
Further, the size of control lever further control card tooth pitch first axle is less than the size of the first wheelbase pulling part.
Further, the first frame body is equipped with the first side plate, the 2nd side plate admittedly in a fixed link front-end edge both sides correspondence, is admittedly equipped with ratchet as the 2nd frame body in a motion bar end edge; First side plate, the 2nd side plate spacing groove central authorities be provided with for axis across middle hole, another relatively on axis rear edge be provided with one can for the first axle across the first hole, then be relatively provided with below the first axle one can for the 2nd axle across the 2nd hole, be more relatively provided with below the 2nd axle one can for the 3rd axle across the 3rd hole; Elastomeric component circle is around in the 2nd axle in spacing groove, makes it have to the first presser feet connecing the 3rd axle, and has to provide and preset elastic force and give the 2nd presser feet of control lever root edge.
Further, first side plate, the 2nd side plate separately relatively on axis front edge be provided with the angular setting hole group that can provide a retaining bolt switching position, this angular setting hole group runs through in the first side plate some jacks, the screw matched then it is provided with as the 2nd side plate, retaining bolt must be worn pull required jack and be screwed together in corresponding screw, make this retaining bolt must across spacing groove, in order to provide the 2nd frame body angular setting use.
Be with, these configurations of the present invention, really can simplify the structural allocation above taking off case before patent greatly, significantly to save the principle and novel capabilities reaching under man-hour and raising efficiency and meet economy, to remove the bad problem taking off case before patent, and can effectively promote manipulation accessibility, it is the innovative techniques of joint rehabilitation device really.
