the adjusting rod 8 and the fixed seat 4 form an elastic structure through the connecting spring 9, and the vertical center line of the adjusting rod 8 and the vertical center line of the rotating rod 5 are overlapped with each other, so that the rotating direction of the rotating rod 5 can be limited by adjusting the position of the adjusting rod 8, and the rotating rod 5 can be locked in a single direction;

the top surfaces of the pawl 12 and the ratchet 7 are both arc-shaped structures, and the pawl 12 and the ratchet 7 are respectively distributed on the outer side surface of the adjusting rod 8 and the inner side surface of the rotating rod 5 at equal angles, so that the unidirectional locking of the rotation of the rotating rod 5 can be realized by utilizing the pawl 12 and the ratchet 7, and the unidirectional locking of the moving directions of the left fixing rod 16 and the right fixing rod 18 can be realized;

the depression section of the locking plate 15 is of an arc-shaped structure, the interior of the locking plate 15 is of a hollow structure, the outer side face of the locking plate 15 is made of transparent plastic, and the inner side face of the locking plate 15 is made of elastic rubber, so that the added amount of water flow in the locking plate 15 can be observed conveniently, and the skin of a patient is prevented from being abraded by the locking plate 15;

the left fixing rod 16 and the right fixing rod 18 are distributed in a staggered and parallel mode, tooth blocks 17 are distributed at equal intervals at the connecting positions of the left fixing rod 16, the right fixing rod 18 and the gear 6, linkage between the left fixing rod 16 and the right fixing rod 18 can be achieved through the design, and the gear 6 is used for synchronously limiting the positions of the left fixing rod 16 and the right fixing rod 18.

The working principle is as follows: when the high-protection orthopedic lower limb rehabilitation exercise device capable of automatically adjusting training intensity is used, firstly, a user firstly fixes the whole device shown in fig. 1 in a working area, when the patient needs rehabilitation exercise, the patient can sit on the seat 20, the protection plate 22 on the side edge of the seat 20 is used for side protection, the patient is prevented from sideslipping, the height of the bottom plate 1 is lower, the patient can conveniently enter the area of the bottom plate 1, in combination with fig. 2 and 6, the patient inserts legs into the oppositely arranged 2 locking plates 15, the positions of the feet are ensured to be right opposite to the adjusting rod 8, the adjusting rod 8 is pressed to move downwards, in combination with fig. 7, the adjusting rod 8 pulls the connecting spring 9 to move downwards, the connecting spring 9 starts to store force, the rotating rod 5 is penetrated by the connecting rod 8, at the moment, the pawl 12 is mutually clamped with the ratchet adjusting rod 7, the locking plate 15 arranged at the upper end of the first, so that the locking plate 15 is attached to the leg position of the patient, at this time, the right fixing rod 18 moves to the left, as shown in fig. 8, the right fixing rod 18 controls the gear 6 meshed and connected at the outer side to rotate clockwise, at this time, the ratchet 7 installed at the inner side of the gear 6 rotates and stirs the pawl 12, the pawl 12 rotates through the rotating shaft 10, and the force is accumulated by using the vortex spring 11 connected to the upper end and the lower end of the rotating shaft 10, when the ratchet 7 and the pawl 12 are disengaged, the vortex spring 11 can drive the rotating shaft 10 to reversely reset, so as to control the pawl 12 to reversely reset, according to the above steps, the clockwise rotation of the gear 6 is smoothly realized, the gear 6 controls the left fixing rod 16 to move to the right, so as to control the second slider 14 to move to the right, further control the locking plate 15 installed at the upper end of the second slider 14 to be attached to the leg position, due to the mutual clamping of the ratchet 7 and the pawl 12, the rotation direction of the gear 6 can be limited, the gear 6 is prevented from rotating anticlockwise by itself, the positions of the left fixing rod 16 and the right fixing rod 18 are limited, the left fixing rod 16 and the right fixing rod 18 are prevented from moving reversely by itself, the locking plate 15 is prevented from moving reversely by itself, and the leg of a patient is quickly locked by the device;

after the locking is finished, a patient holds the supporting rod 21 shown in fig. 2 to apply force, stands up to perform rehabilitation exercise, and simulates walking at ordinary times, the locking plate 15 can be controlled to drive the fixing seat 4 to move, the connecting rod 3 is controlled to move, the adjusting block 303 shown in fig. 4 and hinged to the lower end of the connecting rod 3 slides in the bottom plate 1, the upper end of the connecting rod 3 can pull the extension spring 301 shown in fig. 3 according to the change of the motion position, so that the extension spring 301 stores the force, the resetting can be performed according to the cyclic change of the motion position in the later period, the mounting plate 302 connected with the connecting rod 3 through the extension spring 301 rotates on the support frame 2 hinged to the upper end, the locking plate 15 moves along with the walking force of the legs of the human body, the process needs to overcome the elastic force of the extension spring 301, the self-gravity of the connecting rod 3, the fixing seat 4, the purpose of primary exercise is achieved;

when the training intensity needs to be increased, the thread sealing cover on the upper side of the locking plate 15 can be opened, water flow enters the locking plate 15, the adding capacity can be observed according to the graduated scale 23, the training intensity is increased, articles with increased weight are common, the phenomenon of shortage or loss can not occur, cold water or hot water can be selected according to weather, the comfort of a patient when the patient is in contact with the locking plate 15 is increased, after the water flow is used, the thread sealing cover on the water outlet on the front side of the locking plate 15 shown in the figure 10 can be opened to discharge the water flow, the water flow can be used for watering flowers, cleaning and the like, when the leg locking needs to be released in the later stage, the patient can sit on the seat 20, the seat 20 can also have a rest in time when the patient exercises relatively tired, the situation that the patient falls down due to lack of physical strength is avoided, the foot of the patient is slightly lifted, the connecting spring 9, the gear 6 is released by releasing the connection between the pawl 12 and the ratchet 7, and the locking plate 15 is moved in the reverse direction to release the leg lock, which is the operation of the entire device and is not described in detail in this specification, which is well known to those 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.
