Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of unilateral plain type orthopaedic device for knee proposed by the present invention.
Specific embodiment
As shown in FIG. 1, FIG. 1 is a kind of structural schematic diagrams of unilateral plain type orthopaedic device for knee proposed by the present invention.
Referring to Fig.1, a kind of unilateral plain type orthopaedic device for knee proposed by the present invention, including thigh lattice framing 1, shank lattice framing
2, first gear 3, second gear 4, big leg support 5, first connecting rod 6 and second connecting rod 7, thigh lattice framing 1 and shank lattice framing 2 are hinged,
Thigh lattice framing 1, shank lattice framing 2 inner sidewall on be equipped with bushing, make to dress more comfortable, thigh lattice framing 1, shank lattice framing
2 are strapped in thigh by bandage, on shank respectively；Second gear 4 is rotatably installed in 1 lower part of thigh lattice framing, and first gear 3 rotates
It is mounted at the hinge joint of thigh lattice framing 1 and shank lattice framing 2；First gear 3, second gear 4 are meshed, second gear 4, first
The transmission velocity ratio of gear 3 is 0.5, and second gear 4 is located at 3 top of first gear.
