Description

Foot pedal structure for rehabilitation and use method thereof Technical Field The application relates to the field of rehabilitation equipment, in particular to a pedal structure for rehabilitation, and further relates to a using method of the pedal structure for rehabilitation. Background Leg injury is a relatively common trauma in clinic, and if good rehabilitation training is not available after injury, a life-time sequela may be left. The conventional leg rehabilitation instrument on the market mostly adopts a rehabilitation mode similar to a bicycle pedal, the instrument of the type can only exercise extensor muscles of the legs of a wounded person, the moving range is small, leg joints of the wounded person cannot be sufficiently bent or stretched, and therefore, the patient still needs other instruments to exercise other positions of the legs during rehabilitation. In view of the above, there is a need for a foot pedal structure for rehabilitation and a method of using the same. Disclosure of Invention The application provides a pedal structure for rehabilitation and a use method thereof, aiming at the problem that the existing leg rehabilitation instrument is difficult for a rehabilitation person to exercise at the feet. The pedal structure for rehabilitation comprises a seat unit, a pedal, a damping unit and a bracket, wherein the damping unit is arranged on the bracket and comprises a first piston cylinder, a second piston cylinder, a communicating pipe and a regulating valve, rod cavities of the first piston cylinder and the second piston cylinder face the seat unit, rodless cavities of the first piston cylinder and the second piston cylinder are communicated through the communicating pipe, and the regulating valve is arranged in the communicating pipe so as to regulate the flow area of the communicating pipe through the regulating valve; The end part of the piston rod of the first piston cylinder and the end part of the piston rod of the second piston cylinder are both provided with a pedal, and the first piston cylinder, the second piston cylinder and the cushion of the seat unit are arranged in the same plane. Through adopting above-mentioned technical scheme to gesture with the position of sitting carries out the shank exercise and can effectually reduce dead weight to the burden of shank, thereby can be fit for carrying out some low strength shank exercise, and compare in bicycle formula rehabilitation equipment, locate first piston cylinder and second piston cylinder and seat unit's cushion in the coplanar, when making the rehabilitation personnel step on the footboard on first piston cylinder and the second piston cylinder under the state with the position of sitting, the shank of rehabilitation personnel still can have a relatively big range of buckling and stretching, thereby can make rehabilitation personnel's ankle joint, knee joint even hip joint homoenergetic obtain effectual activity and exercise. Further, a binding band is arranged on the pedal. Through adopting above-mentioned technical scheme, can bind the foot of rehabilitation personnel on the footboard to can prevent rehabilitation personnel's the easy injured condition of landing from the footboard when taking exercise, and bind rehabilitation personnel's foot on the footboard can be convenient for rehabilitation personnel to apply pulling force to the footboard, so that rehabilitation personnel when exerting thrust to the footboard, the anterior thigh muscle crowd of its shank contracts the posterior thigh muscle crowd and relaxs, when exerting pulling force to the footboard, the anterior thigh muscle crowd of its shank relaxs posterior thigh muscle crowd, thereby make anterior thigh muscle crowd and posterior thigh muscle crowd all can obtain good relaxation, the exercise effect is better. Further, a connecting shaft is arranged between the pedal and the piston rod, the connecting shaft comprises a fixedly connected section and a pin joint section, the fixedly connected section is a square column, a pin hole matched with the pin joint section is formed in the end portion of the piston rod, and the pedal is hinged to the pin joint section. Through adopting above-mentioned technical scheme, can realize the rotation of footboard to can be when the shank of rehabilitation personnel bends and stretches, the footboard can follow-up when ankle joint takes place to rotate. Further, be equipped with gear and stopper on the support, the gear is located first piston cylinder with between the piston rod of second piston cylinder and articulate on the support, first piston cylinder with all be equipped with on the piston rod of second piston cylinder with gear engaged with rack, the stopper includes the pushing cylinder and locates the locking piece on the push rod of pushing the cylinder, the pushing cylinder can drive the locking piece is close to or keeps away from the gear, just the locking piece is close to can with gear engagemen
