[0002] The success of surgery does not mean the recovery of joint function. For the patient's functional recovery, the success of the surgery is certainly important, but the subsequent rehabilitation exercises cannot be ignored. When a limb is injured, not only the bones are injured, but the surrounding soft tissues also need to be repaired. Scar contracture and tendon contracture that occur after trauma need to be stretched through exercise to obtain better function. Early functional exercise is easier to achieve joint function recovery than later exercise, while promoting limb swelling and accelerating local blood circulation, thereby promoting healing.

[0033] At the same time, in order to facilitate the installation and fixation of the support arm 2, a support ring 20 is provided in the middle of the support arm 2 and is sleeved on the cross bar 1. The upper thread of the support ring 20 is connected with a locking bolt A201 whose end is against the cross bar 1.

[0034] Based on the above configuration, in order to facilitate the adjustment of the installation height of the two cross bars 1 according to the needs during use, such as Figure 2 The vertical plate 13 provided by the present invention is provided with a pair of rectangular holes 131 along its length direction; one side of the vertical plate 13 is fixedly connected with an "L"-shaped plate 15 and a "Z"-shaped plate 14 by a bolt assembly 15 penetrating the rectangular hole 131, and the "Z"-shaped plate 14 is located above the "L"-shaped plate 15; and a locking bolt B141 is threadedly connected to the "Z"-shaped plate 14; that is, when in use, by adjusting the "L"-shaped plate 15 and the "Z"-shaped plate 14 to move along the length direction of the rectangular hole 131, the protruding height of the end of the vertical plate 13 from the upper surface of the bed after installation is adjusted.

[0035] When in use, in order to adjust the number of counterweight plates 4 connected to the ends of the vertical rods 31 according to the needs of the user, such as Figure 5 The counterweight plate 4 provided by the present invention includes a plate body 41, a boss 42 is arranged on the upper surface of the plate body 41, and a slot 43 for inserting the boss 42 is arranged on the bottom side of the plate body 41; a through hole A44 is arranged on the boss 42, and a through hole B45 is arranged on the plate body 41; a vertical rod 31 is provided with a plurality of through holes C32 along its length direction; when two adjacent counterweight plates 4 are stacked together, the through hole A44 on one plate body 41, the through hole B45 on the other plate body 41, and a through hole C32 on the vertical rod 31 are in a concentric structure; at this time, the pin rod passes through the through hole A44 and the through hole B45 in the concentric structure.

[0036] At the same time, when using Figure 5 In order to facilitate the use of a pin rod to connect the vertical rod 31 and the counterweight plate 4, the pin rod provided in this scheme includes a gripping section 46 and an insertion section 462 integrally formed at the end of the gripping section 46, and a convex ring 461 is provided between the gripping section 46 and the insertion section 462, and the convex ring 461 is against the outer side of the plate body 41.

[0037] The bracelet is a circular ring; Figure 7 The pedal includes a base plate 301, and three fixing straps 302 are fixed to the sole of the foot on the footrest surface of the base plate 301, and one end of the fixing strap 302 is fixed to the base plate 301; a protrusion 304 is provided on the base plate 301 at the other end of the fixing strap 302, and a plug hole for the fixing strap 302 to pass through is provided on the protrusion 304; a plurality of fixing holes 303 are provided at the end of the fixing strap 302, and a limiting bolt 305 extending into the plug hole is threadedly connected to the protrusion 304, and the limiting bolt 305 is inserted into the fixing hole 303 of the fixing strap 302.

[0038] Specifically, Figure 6 , and also includes a cylinder 40 for storing the counterweight plate 4. The outer wall of the cylinder 40 is provided with an opening 401 for the pin to pass through in the vertical direction. The bottom end of the cylinder 40 is fixed on a bottom plate 403; a reinforcement block 402 is provided between the outer peripheral side wall of the cylinder 40 and the bottom plate 403.

[0039] It can be known that when the counterweight plate 4 is driven to move upward along the inner wall of the cylinder 40 during use, there is resistance due to the gravity of the counterweight plate 4, and when the counterweight plate 4 is controlled to move downward along the inner wall of the cylinder 40, the gravity of the counterweight plate 4 causes the foot pedal to detach from the sole of the foot, that is, when in use, it is necessary to control the counterweight plate 4 to move slowly downward along the inner wall of the cylinder 40, thereby achieving the need to provide damping for the counterweight plate 4 when controlling the counterweight plate 4 to move downward along the inner wall of the cylinder 40 during use.

[0040] Specifically, Figure 8 The bottom side surface of the cylinder 40 is provided with an inner sleeve 47 and an outer sleeve 48 which are sealed with each other, and a spring 471 is connected between the inner sleeve 47 and the outer sleeve 48, and a support block 404 for supporting the counterweight plate 4 is provided on the inner wall of the cylinder 40; an air pressure sensor is provided in the space formed by the outer sleeve 48 and the inner sleeve 47; the bottom end of the vertical rod 31 is connected to the top of the inner sleeve 47 through an elastic connecting rope 49; and a plurality of protrusions 405 are provided on the outer peripheral side wall of the cylinder 40, and an installation cavity 406 recessed into the protrusion 405 is provided on the inner side wall of the cylinder 40 located at the protrusion 405, and a movable block 408 sliding along the inner wall of the installation cavity 406 is connected to the installation cavity 406 through a telescopic motor 407, and a damping layer 409 is provided on the end of the movable block 408.

[0041] Based on the above, during use, when the counterweight plate 4 is controlled to move upward along the inner wall of the cylinder 40, the bottom end of the vertical rod 31 is detached from the top of the inner sleeve 47. At this time, under the action of the spring 471, the pressure signal detected by the air pressure sensor gradually decreases; at the same time, when the counterweight plate 4 moves upward to the maximum height, the elastic connecting rope 49 is controlled to pull the inner sleeve 47 to move upward until the top of the inner sleeve 47 is against the support block 404, and the pressure signal detected by the air pressure sensor is reduced to the minimum value; when the counterweight plate 4 moves downward along the inner wall of the cylinder 40, the elastic connecting rope 49 is relaxed first, and the inner sleeve 47 moves downward until its top is detached from the bottom side of the support block 404. At this time, the pressure signal detected by the air pressure sensor increases, and it is determined that the counterweight plate 4 needs to be controlled to move downward along the inner wall of the cylinder 40, and then the telescopic motor 407 is controlled to extend to drive the movable block 408 to slide along the inner wall of the installation cavity 406. At this time, the damping layer 409 is against the outer peripheral side wall of the counterweight plate 4 to form a damping effect.

[0042] At the same time, in the above-mentioned process, when the counterweight plate 4 moves downward along the inner wall of the cylinder 40 to the maximum depth, that is, when the counterweight plate 4 connected to the lowest end of the vertical rod 31 abuts against the top counterweight plate 4 located in the cylinder 40, the inner sleeve 47 and the outer sleeve 48 return to their initial state, that is, the pressure signal detected by the air pressure sensor returns to the initial value, indicating that the counterweight plate 4 moves downward along the inner wall of the cylinder 40 to the initial position. At this time, the telescopic motor 407 is controlled to contract and drive the movable block 408 to slide along the inner wall of the installation cavity 406, and the damping layer 409 is detached from the outer peripheral side wall of the counterweight plate 4.

[0043] Specifically, the cross-sections of the boss 42 and the slot 43 are rectangular, triangular, elliptical or pentagonal; Figure 3 , and two arc-shaped blocks 202 are provided on the support ring 20, and the two arc-shaped blocks 202 form a channel for the traction rope 3 to pass through.
