Connecting plates are fixedly connected to both ends of the rotating shaft extending to the outside of the fixed block. In the present utility model, by driving two pedals with two legs, the leg strength of the patient can be exercised. Moreover, due to the gravity of the gravity wheel, the resistance during the rotation of the rotating shaft can be increased, further improving the practicability of the exercise.

[0003] In actual application, when patients are performing rehabilitation training, they often need to continuously adjust the resistance according to the training duration. During the adjustment process, patients need to bend down to operate, and then sit upright on the seat to try stepping. This is both cumbersome and time-consuming. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a leg rehabilitation device for surgical nursing, which solves the problem that when patients are performing rehabilitation training, they often need to continuously adjust the resistance according to the training duration. During the adjustment process, patients need to bend down to operate, and then sit upright on the seat to try stepping. This is both cumbersome and time-consuming.

[0005] To achieve the above object, the utility model provides the following technical solution: A leg rehabilitation device for surgical nursing, including a bottom plate, a seat is connected to the bottom plate, an adjusting rod is slidably connected inside the bottom plate, a rotating wheel is penetrated and rotatably connected inside the adjusting rod, a pedal is rotatably connected outside the adjusting rod, a resistance device is connected inside the adjusting rod, and an adjusting device is connected below the resistance device.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. For the leg rehabilitation device used in surgical nursing, by setting components such as a housing, nut, threaded rod, bearing, push plate, and pull-back spring, when it is necessary to adjust the resistance, the user only needs to lie on the seat at this time, and then rotate the threaded rod. The threaded rod drives the bearing to move through the nut, and the bearing drives the push plate to slide in the housing. Subsequently, the push plate applies a thrust to the pull-back spring, causing the pull-back spring to compress. During compression, the pull-back spring applies an elastic force to the moving block, driving the moving block to move. The moving block drives the sphere, connecting rod, and sliding rod to move. At this time, the sliding rod slides through the sliding sleeve, and the sliding rod drives the arc plate to move when sliding. Subsequently, the arc plate contacts the rotating wheel. When the moving block moves a certain distance and stops, the compression degree of the pull-back spring determines the pressure of the arc plate on the rotating wheel, so that the resistance can be adjusted while sitting still on the seat, avoiding the problem that when patients are undergoing rehabilitation training, they often need to continuously adjust the resistance according to the training duration. During the adjustment process, the patient needs to bend down to operate, and then sit upright on the seat to try stepping, which is both cumbersome and time-consuming.

[0016] 2. For the leg rehabilitation device used in surgical nursing, by setting components such as a connecting seat, adjusting plate, limiting hole, and limiting rod, when patients have different heights, the limiting rod can be removed at this time, and then the adjusting plate is pulled to slide in the connecting seat. At this time, the adjusting plate drives the first locking plate and the second locking plate to move. The second locking plate drives the housing to rotate through the sphere when moving. At this time, the second locking plate can rotate freely in the first locking plate. When the adjusting plate slides to the appropriate area, the limiting rod is inserted into the corresponding limiting hole, thus achieving free adjustment for patients with different heights.

[0022] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: a leg rehabilitation device for surgical care, including a bottom plate 1, a seat 2 is connected to the bottom plate 1, an adjusting rod 3 is slidably connected inside the bottom plate 1, a rotating wheel 4 is penetrated and rotatably connected inside the adjusting rod 3, a pedal 5 is rotatably connected outside the adjusting rod 3, a resistance device 6 is connected inside the adjusting rod 3, an adjusting device 7 is connected below the resistance device 6. The resistance device 6 includes a housing 601, a nut 602 is provided inside the housing 601, and a threaded rod 603 is threadedly connected inside the nut 602; one end of the threaded rod 603 is connected with a bearing 604, and a push plate 605 is connected outside the bearing 604. By setting the threaded rod 603, the bearing 604 and the push plate 605, the threaded rod 603 cooperates with the bearing 604 and the push plate 605, realizing that when the threaded rod 603 rotates, it can freely rotate inside the bearing 604, so that when the bearing 604 moves, the push plate 605 will not rotate;

[0024] A moving block 607 is slidably connected inside the housing 601, a pull-back spring 606 is provided inside the housing 601, a sphere 608 is rotatably connected inside the moving block 607, a connecting rod 609 is connected below the sphere 608, a slide bar 610 is connected below the connecting rod 609, a slide sleeve 611 is slidably connected outside the slide bar 610, and an arc plate 612 is connected below the slide bar 610. By setting the arc plate 612, anti-slip lines are provided on the inner side of the arc plate 612, making the effect of resistance adjustment better;

[0025] The part of the runner 4 that penetrates outside the adjusting rod 3 is connected inside the pedal 5. The end face of the push plate 605 is circular. The push plate 605 is slidably connected inside the housing 601. One end of the pulling-back spring 606 is connected inside the push plate 605, and the other end of the pulling-back spring 606 is connected inside the moving block 607. By providing the pulling-back spring 606, when the threaded rod 603 is not rotated, at this time the pulling-back spring 606 exerts an elastic force on the moving block 607 to keep it stable. When the threaded rod 603 is rotated in the reverse direction, at this time the pulling-back spring 606 exerts an elastic force on the moving block 607, and the elastic force drives the moving block 607 to move, so that it can be quickly reset;

[0026] The sliding sleeve 611 is connected through and inside the adjusting rod 3. The arc-shaped plate 612 corresponds to the position of the runner 4. The adjusting device 7 includes a connecting seat 71. The connecting seat 71 is connected to the adjusting rod 3. An adjusting plate 72 is slidably connected inside the connecting seat 71. A number of limiting holes 73 are provided inside the adjusting plate 72. A limiting rod 74 is slidably connected inside the connecting seat 71. By providing the limiting rod 74 and the limiting holes 73, the limiting rod 74 cooperates with the limiting holes 73 to realize the limiting of the limiting holes 73 by the limiting rod 74 and avoid the shaking of the limiting holes 73;

[0027] The limiting rod 74 is clamped in one of the limiting holes 73. A first locking plate 75 is connected to the adjusting plate 72. A second locking plate 76 is movably connected inside the first locking plate 75. The second locking plate 76 is connected to the lower part of the housing 601.

[0028] The working principle of the present utility model is as follows:

[0029] When resistance adjustment is required, simply lie on the seat 2 at this time, and then rotate the threaded rod 603. The threaded rod 603 drives the bearing 604 to move through the nut 602. The bearing 604 drives the push plate 605 to slide within the housing 601. Subsequently, the push plate 605 exerts a thrust on the pulling-back spring 606, causing the pulling-back spring 606 to be compressed. During compression, the pulling-back spring 606 exerts an elastic force on the moving block 607, driving the moving block 607 to move. The moving block 607 drives the sphere 608, the connecting rod 609, and the sliding rod 610 to move. At this time, the sliding rod 610 slides through the sliding sleeve 611. When the sliding rod 610 slides, it drives the arc-shaped plate 612 to move. Subsequently, the arc-shaped plate 612 contacts the runner 4. When the moving block 607 moves a certain distance and then stops moving, the degree of compression of the pulling-back spring 606 determines the pressure of the arc-shaped plate 612 on the runner 4. When the heights of patients are different, the limiting rod 74 can be removed at this time, and then the adjusting plate 72 is pulled to slide within the connecting seat 71. At this time, the adjusting plate 72 drives the first locking plate 75 and the second locking plate 76 to move. When the second locking plate 76 moves, it drives the housing 601 to rotate through the sphere 608. At this time, the second locking plate 76 can rotate freely within the first locking plate 75. When the adjusting plate 72 slides to an appropriate area, the limiting rod 74 is inserted into the corresponding limiting hole 73. Thus, the adjustment of the resistance is completed.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connection", "sliding connection", and "hinged connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0031] The above has made a detailed description of the preferred embodiment of this patent, but this patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the purpose of this patent.
