It is fixed, it rotates and is overlapped for wearing the via hole of articulated shaft 331 with the first hinge hole 11 on lattice framing 32, the first limiting slot 321 and the
One limit hole 12 is overlapped.First joint portion 10 and second joint portion 20 partially overlap.Fixed part 33 and second joint portion 20 are opposite
Fixed, articulated shaft 331 and limited post 332 on fixed part 33 sequentially pass through the second arc panel 2, the first arc panel 1, rotation lattice framing
32 and adjustment gear 34, wherein articulated shaft 331 passes through 11 after the first hinge hole, sequentially passes through rotation lattice framing 32 and adjustment gear
34 via hole sequentially passes through the first limiting slot 321 and the second limiting slot 341 after limited post 332 passes through the first limit hole 12.
Certainly, in other embodiments, rotation lattice framing 32 can be a part of the first joint portion 10, i.e. rotation lattice framing 32
It is integral structure with the first joint portion 10.Fixed part 33 can be a part in second joint portion 20, i.e. fixed part 33 and
Two joint portions 20 are integral structures.Preferably, for the comfort level for improving user, the side that fixed part 33 is contacted with user
The padded coamings such as sponge can be wrapped up.
It as shown in Figure 8 and Figure 9, include two symmetrically arranged adjusting chucks 3 in the present embodiment, two adjust chuck 3
Rotate the first limiting slot 321 on lattice framing 32, the second limiting slot 341 and the third limiting slot where plectrum 342 in adjustment gear 34
303 are symmetrical arranged, correspondingly, the position of the first limit hole 12 on two the first joint portions 10 is also symmetrical arranged, it is ensured that two
A adjusting chuck 3 can cooperate, and brace is adjusted to the same direction.
After installation, it is located at original state when adjusting chuck 3, i.e. user dresses cruciate ligaments of knee joint brace and is kept upright
When, limited post 332 is located at the end of the first limiting slot 321 and the second limiting slot 341, the second limiting slot 341 of adjustment gear 34
The range being overlapped with the first limiting slot 321 reaches maximum.
Since original state limited post 332 is located at the end of the first limiting slot 321, the first arc panel 1 and the second arc are adjusted
When the relative position of shape plate 2, the second arc panel 2 opposite first arc panels 1 can be limited and moved backward.If shank can be forward
Mobile, the unprotected limitation of knee joint may aggravate the joint burden of user's injury, brace limit provided in this embodiment
Having made knee joint cannot move forward, and eliminate this risk.
Certainly, in other examples, the position of the first limiting slot 321 and removable can also be adjusted according to actual needs
Dynamic range.
In the present embodiment, angle is voluntarily adjusted for the convenience of the users, and limited post 332 is located under the first limiting slot 321
End, naturally it is also possible to adjust limited post 332, limited post 332 is arranged in the upper end of the first limiting slot 321, correspondingly, the second limit
Position hole 22 is located at the surface of the second hinge hole 21.
It should be noted that in other embodiments, if necessary to further limit kneed scope of activities, Huo Zhexu
Make knee joint fixed under the conditions of keeping curved, two adjustment gears 34, and two can also be set in adjusting chuck 3
A adjustment gear 34 is relatively rotatable to each other.By adjusting the position of two adjustment gears 34, change the second limiting slot 341 and first
Limiting slot 321 is overlapped the size of range, and brace can be fixed on to required bending angle, or further limits turning for joint
Dynamic range.
In use, the first arc panel 1 is fixed on front side of the thigh of user using bandage, the second arc panel 2 is fixed on
The posterior leg of user adjusts the position of the first arc panel 1 and the second arc panel 2 and the elasticity of bandage as needed.
The limit switch 311 for adjusting chuck 3 is moved up, locking plate 313 is engaged with the releasing of adjustment gear 34, by stirring 342 turns of plectrum
Dynamic adjustment gear 34 adjusts the part that the second limiting slot 341 and the first limiting slot 321 are overlapped, and then rotation lattice framing is adjusted flexibly
32 can adjust the joint flexion-extension motion range of brace relative to the range of the fixed movement of portion 33.After adjusting, limit is moved down
Switch 311, locking plate 313 are engaged with adjustment gear 34, and adjustment gear 34 is prevented to rotate, and pillar 312 and intermediate plate 302 cooperate,
Ensure that locking plate 313 will not be bounced voluntarily.
