The working principle of the embodiment is as follows: when the suspended leg training device convenient for resistance adjustment for orthopedic rehabilitation is used, as shown in fig. 1-2, the device is firstly placed at a corresponding position, then a patient sits on the seat 2, then the patient can extend two feet into the lantern ring 11, the patient presses the two feet downwards with force, so that the lantern ring 11, the fixing plate 10 and the connecting seat 9 are driven to descend together, the elastic spring 15 at the bottom of the connecting seat 9 is pressed, the connecting seat 9 is provided with the rack 12, the rack 12 can descend together with the connecting seat 9, the connecting gear 13 and the first rotating shaft 14 are driven to rotate anticlockwise, when the patient presses the lantern ring 11 to the lowest end, the two legs are loosened, at the moment, the connecting seat 9 resets and moves upwards under the action of the elastic spring 15, so that the rack 12 can ascend, the connecting gear 13 and the first rotating shaft 14 are driven to rotate clockwise, the patient can repeat the action to train the legs;

when the training resistance needs to be increased, a user can start the water pump 20, the water pump 20 pumps water in the water storage tank 18 through the first connecting pipe 21 and then conveys the water upwards through the second connecting pipe 22, because the top of the second connecting pipe 22 is connected with the shunt pipe 25 as shown in fig. 4 and 6-7, the water enters the shunt pipe 25 and flows into the water storage tank 18, so that the water is recycled, water resources are saved, because the shunt pipe 25 and the second rotating shaft 17 are on the same horizontal line, when the patient presses downwards, according to the above principle, the first rotating shaft 14 rotates anticlockwise, and drives the second rotating shaft 17 to rotate anticlockwise together through the driving belt 16, and when the shunt pipe 25 discharges water, the resistance is caused to the second rotating shaft 17, so that the strength of the patient during training is increased, and meanwhile, the flow control valve 23 is installed on the second connecting pipe 22, therefore, the flow of water can be controlled through the flow control valve 23, the adjustment of the resistance is realized conveniently, and the check valve 26 is arranged on the shunt pipe 25, so that a patient can train the left leg or the right leg independently according to the requirement of the patient during training, only the corresponding check valve 26 is needed to be closed, water cannot enter the closed shunt pipe 25, the training operation of the patient is further facilitated, and the flexibility of the device during use is improved;

in the process that the connecting seat 9 moves up and down, the limiting blocks 901 on the side walls of the connecting seat 9 slide along the vertical plates 8, so that the connecting seat 9 moves more stably, if a patient needs to adjust the sitting posture, such as moving the seat 2 forward, at this time, as shown in fig. 5 and 8, the inserting rod 29 is taken out from the limiting hole 28, then the handle 27 is screwed clockwise, so that the handle 27 drives the worm 7 to rotate together, the worm 7 drives the worm wheel 6 and the screw rod 5 to rotate together, because the screw rod 5 is in threaded connection with the connecting plate 4, the connecting plate 4 can move forward, so that the supporting column 3 and the seat 2 are driven to move forward together, the position of the seat 2 is adjusted, as shown in fig. 3, when the connecting plate 4 moves, the connecting blocks 401 on the front side and the rear side of the connecting plate 4 can slide along the base 1, so as to, further ensuring stable use of the device, instead of requiring a backward movement of seat 2, it is sufficient to rotate handle 27 counterclockwise, which is the working process of the entire device, and is not described in detail in this specification, which is well known to a person skilled in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
