Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the present invention includes that above-knee thigh straightening members 1, thigh straightening mechanism fixture 2, shank correct structure Part 3, shank straightening members fixture 4, crank levers assembly, footrest connect rope 5 and footrest 6, and described above-knee thigh corrects structure Part 1 and shank straightening members 3 are respectively equipped with opening, and it is solid that the both sides of described opening are connected and installed with thigh straightening mechanism respectively Locking member 2 and shank straightening members fixture 4, described crank levers assembly includes crank levers 7, crank levers rotary shaft 8 and To a pair pulley 9 for limiting crank levers mobile space, one end of described crank levers 7 is provided with rotating shaft installing hole, another End is provided with connection rope mooring hole, and the rotating shaft installing hole of one end of described crank levers 7 is rotatably pacified by crank levers rotary shaft 8 Being contained on above-knee thigh straightening members 1, the pair of pulley 9 is movably arranged on shank straightening members 3 by rotating shaft respectively, The middle part of described crank levers rotary shaft 8 is stuck between a pair pulley 9, and described footrest 6 connects one end of rope 5 and ties up to crank thick stick At the connection rope mooring hole of bar 7, described footrest 6 is connected to footrest and connects the other end of rope 5.
Described thigh straightening members 1, shank straightening members 3 and footrest 6 are respectively adopted low temperature thermoplastic board mold molding.
Also having described thigh straightening mechanism fixture 2 and shank straightening members fixture 4 is VELCRO respectively.
Described footrest connects rope 5 employing stretch cord.
Described footrest connects rope 5 employing non-stretchable rope.
Working method and principle, the present invention uses following steps to carry out the making of gait correcting device:
Step one: above-knee 20cm measures thigh circumference degree, application low temperature thermoplastic plate makes above-knee thigh straightening members, opening inwardly (evil spirit Art patch is fixing, adjusting elasticity), in the middle part of above-knee thigh straightening members, crank levers rotary shaft is installed；
Step 2: under capitulum fibulae, 10cm measures calf circumference degree, application low temperature thermoplastic plate makes shank straightening members, and opening is inside (VELCRO is fixed, adjusting elasticity), installs a pair pulley of crank levers above and below in the middle part of shank straightening members, limit And control to move space on when crank levers slides；
