[0027] The locking knob 3 comprises a locking sleeve arranged on the upper side of both ends of the fixed rod, a locking screw threadedly connected inside the locking sleeve, a locking plate and a locking handle installed at both ends of the locking screw. The telescopic rod 2 and the fixed rod 1 can be clamped, ensuring that the telescopic rod 2 will not retract after being extended, and ensuring the stability of the fixation.
[0028] The mounting clip 4 comprises a U-shaped block mounted at the end of the telescopic rod 2, a fixed nut arranged at the middle of the lower end of the U-shaped block, a fixed screw threadedly connected inside the fixed nut, fixed plates arranged at both ends of the fixed screw, and a fixed knob.
[0029] Two first adjusting frames 8 are mounted on the first sliding grooves 6 on the upper and lower sides of the mounting frame 5, and only one second adjusting frame 9 is mounted on the second sliding groove 7 on the left and right sides of the mounting frame 5. The ends of the second adjusting frames 9 on the left and right sides are connected to the left connecting block 10, and the ends of the first adjusting frames 8 on the left and right sides of the first sliding groove 6 are also connected to the right connecting block 10. An elastic rope 101 is arranged between the left and right connecting blocks 10. By fixing the feet to the left and right connecting blocks 10, the patient's feet can move up and down and also separate left and right. The elastic rope 101 provides resistance when the legs are spread apart.
[0030] The first adjusting frame 8 and the second adjusting frame 9 have the same structure, both comprising a sliding block 81 slidingly mounted inside the sliding groove, an expansion hole 82 arranged at the middle of the sliding block 81, a pull rod 83 slidingly mounted inside the expansion hole 82, a pressing block 84 arranged at the upper end of the pull rod 83, an adjusting groove 85 mounted at the outer end of the sliding block 81, an adjusting mechanism 87 arranged at the upper end of the adjusting groove 85, an adjusting spring 86 connecting the adjusting mechanism 87 and the pressing block 84, a supporting spring 88 connecting the pressing block 84 and the adjusting groove 85, the adjusting spring 86 and the supporting spring 88 being located inside the adjusting groove 85, and the lower end of the pull rod 3 being fixedly connected to the connecting block 10. The adjusting mechanism 87 comprises a nut 871 arranged at the upper end of the adjusting groove 85, an adjusting screw 872 threadedly connected inside the adjusting nut 871, adjusting plates 873 and adjusting handles 874 mounted at both ends of the adjusting screw 872. The first adjusting frame and the second adjusting frame can be used for exercising the feet. By sliding the first adjusting frame and the second adjusting frame on the first sliding groove and the second sliding groove, respectively, the patient's lower limbs can simulate a walking posture to exercise. By arranging the first return spring 14, the second return spring 15, and the adjusting spring 86, a certain resistance is provided during exercise, which has an exercise effect. The specific principle is that the movement of the feet pushes the pull rod 83 and the foot pedal rod 11, which presses the adjusting spring 86, the supporting spring 88, the first return spring 14, and the second return spring 15. The elasticity of the springs provides resistance for the movement of the feet, which can achieve exercise.
[0031] Meanwhile, the adjusting mechanism 87 is arranged to adjust the exercise intensity, specifically, the adjusting handle 874 is rotated to press the adjusting plate 873 downward to compress the adjusting spring 86, so that the adjusting spring 86 is shortened, at this time, the resistance of the extrusion block 84 pushing the adjusting spring 86 is increased, and the exercise intensity is increased, on the contrary, the adjusting handle 874 is rotated to adjust the adjusting plate 873 upward to release the adjusting spring 86, so that the adjusting spring 86 is lengthened, at this time, the resistance of the extrusion block 84 pushing the adjusting spring 86 is reduced, and the exercise intensity is reduced.
[0032] The foot pedal mechanism 13 comprises a foot pedal 131 arranged at the front end of the foot pedal rod 11, a bottom pocket 132 arranged at the lower end of the foot pedal 131, restraint belts 133 arranged symmetrically at both sides of the foot pedal 131, and magic tapes arranged at the ends of the two restraint belts 133 to be connected to each other. The patient's feet can be firmly connected to the device.
[0033] Embodiment 2
[0034] Working principle: when using the device, first install the device, when installing, place the fixed rod 1 at the tail end of the bed, then pull the two installation clamps 3 to make the telescopic rod 2 extend out of the fixed rod 1 by a certain length, then move the two installation clamps 3 close to each other, and then place the edge of the bed in the U-shaped block of the two installation clamps 3, then rotate the locking knob to fix the telescopic rod 2 to avoid the telescopic rod 2 from retracting, then rotate the fixing knob to use the fixing plate to clamp the edge of the bed between the U-shaped block and the fixing plate, and the installation and fixation of the device are completed.
[0035] When in use, the patient places both feet on the two foot pedal mechanisms 13, places the heels in the bottom pockets 132, and fixes the feet by using the restraint belts 133 (the symmetrically arranged restraint belts are connected by magic tapes to form restraint on the patient's feet), then the patient can perform the action of stretching and bending the legs on the bed (simulating the walking posture), at this time, the patient moves the legs up and down to extrude the adjusting spring 86 in the first adjusting frame 8; the stretching and bending of the legs extrudes the first and second return springs 14 and 15; when the patient opens and closes the legs left and right, the adjusting spring 86 in the second adjusting frame 9 is extruded; the patient has a certain resistance when exercising the lower limbs, thereby achieving the exercise effect;
[0036] When the patient exercises the legs by moving up and down, the second adjusting frame 9 moves up and down in the second sliding groove 7, the extrusion block 84 in the first adjusting frame 8 moves up to extrude the telescopic spring 86, and the extrusion block 84 moves up to pull the supporting spring 88, the deformation of the telescopic spring 86 and the supporting spring 88 provides resistance for the leg action, thereby achieving the exercise effect;
[0037] When the patient moves the legs left and right, the first adjusting frame 8 moves left and right in the first sliding groove 6, the pressing block 84 in the second adjusting frame 9 moves up to press the telescopic spring 86, and the pressing block 84 moves up to pull the supporting spring 88, and the elastic rope 101 between the two connecting blocks 10 is stretched, the deformation of the telescopic spring 86, the supporting spring 88 and the elastic rope 101 provides resistance to the leg movement, and the exercise effect is achieved;
[0038] During the exercise, according to the recovery of the patient, the adjusting handle 874 of the adjusting mechanism 87 is rotated to make the adjusting plate 873 press or release the adjusting spring 86, and the adjusting plate 873 is pressed down or adjusted up under the mutual action of the force, so as to adjust the exercise intensity. Specifically, the adjusting plate 873 is pressed down to compress the adjusting spring 86 by rotating the adjusting handle 874, at this time, the adjusting plate 873 is pressed down to press the supporting spring 88 under the pressing of the adjusting spring 86, so that the active distance of the adjusting spring 86 and the supporting spring 88 is shortened, at this time, the resistance of the adjusting spring 86 pushed by the pressing block 84 is increased, and the exercise intensity is increased, on the contrary, the adjusting plate 853 is adjusted up to release the adjusting spring 86 and the supporting spring 88 by rotating the adjusting handle 854, so that the active distance of the adjusting spring 86 and the supporting spring 88 is increased, at this time, the resistance of the adjusting spring 86 pushed by the pressing block 84 is reduced, and the exercise intensity is reduced.
