DETAILED DESCRIPTION

[0016] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0017] Example 1

[0018] A leg rehabilitation training device described in this embodiment, such as Figure 1 to Figure 2 As shown, it includes a horizontally arranged flat plate 1, with supporting legs 16 vertically fixed to the bottom of the flat plate 1, and there are four supporting legs 16, which are distributed in a rectangular shape at the bottom of the flat plate 1, and the upper ends of the supporting legs 16 are all fixed to the bottom of the flat plate 1;

[0019] The right end of the plate 1 is provided with two through slots communicating with each other vertically, and there are two through slots, which are respectively provided at the front and rear sides of the right end of the plate 1;

[0020] The through slots are hinged with movable plates 2 that swing up and down. The left end of the movable plate 2 is hinged to the left slot wall of the through slot through a hinge seat. The hinge seat is a prior art, including two fixed plates. The fixed plates are fixed to the left slot wall of the through slot. A rotating shaft is horizontally fixed between the two fixed plates. The left end of the movable plate 2 is fixed to the rotating shaft, and the movable plate 2 is driven to swing up and down through the rotating shaft.

[0021] A support plate 15 is horizontally fixed in the through groove at the bottom of the movable plate 2, the left end of the support plate 15 is fixed on the left groove wall of the through groove, and the support plate 15 is horizontally fixed below the movable plate 2, and the support plate 15 provides support for the movable plate 2, and bears the weight of the patient's legs together;

[0022] The bottom of the movable plate 2 is provided with a locking plate 14, which is in an "L"-shaped structure. One end of the locking plate 14 is hinged to the bottom of the movable plate 2, and the locking plate 14 is hinged to the bottom of the movable plate 2 through a hinge seat, and the locking plate 14 swings left and right around the hinge seat; the other end is fixed to the support plate 15 by bolts, and the lower end of the locking plate 14 is provided with a through hole communicating with the upper and lower ends, and the right end of the support plate 15 is provided with a threaded hole communicating with the through hole. The bolt passes through the through hole and is inserted into the threaded hole. The locking plate 14 is locked by the threaded cooperation between the bolt and the threaded hole. The plate 14 is fixed to the right end of the support plate 15, so that the movable plate 2 is fixed to the support plate 15, preventing the movable plate 2 from rotating upward when the patient is doing knee flexion training, thereby ensuring stability during use; this paragraph of text as a whole constitutes a fixing component for fixing the movable plate 2 to the support plate 15. Of course, the fixing component can also be in the form of a buckle, with a buckle installed at the bottom of the movable plate 2, and a slot matching the buckle is opened at the right end of the support plate 15, and the movable plate 2 is fixed to the support plate 15 by inserting the buckle into the slot;

[0023] The movable board 2 is provided with a pedal 4 that is slidably matched therewith. The pedal 4 is in an "L"-shaped structure. The pedal 4 slides left and right along the length direction of the movable board 2. The patient's foot is fixed on the pedal 4. When the patient bends his knee, the pedal 4 is driven to slide on the movable board 2.

[0024] An elastic band 5 is installed on the pedal 4, and the patient's foot is fixed on the pedal 4 through the elastic band 5;

[0025] A fixing plate 9 is fixed to the right end of the flat plate 1, and a vertical plate 13 is fixed to the flat plate 1 on the left side of the fixing plate 9. The fixing plate 9 and the vertical plate 13 are both fixed to the flat plate 1 between the two through grooves.

[0026] A cross bar 11 is fixed horizontally between the vertical plate 13 and the fixed plate 9, and a slider 8 is mounted on the cross bar 11. The slider 8 is provided with through holes that are connected to the left and right. The cross bar 11 is inserted into the through holes, and the slider 8 slides left and right along the length direction of the cross bar 11; a spring 10 is mounted on the cross bar 11 between the slider 8 and the vertical plate 13, and the left end of the spring 10 is fixed to the right side wall of the vertical plate 13, and the right end of the spring 10 is fixed to the left end of the slider 8; in the natural state of the spring 10, the slider 8 rests on the fixed plate 9, and the slider 8 is pushed to the left by the spring 10. The patient needs to overcome the elastic force of the spring 10 and then push the pedal 4 to move, thereby increasing the training intensity; traction ropes 7 are fixed on both sides of the slider 8, such as Figure 1As shown, traction ropes 7 are fixed to the upper and lower ends of the slider 8; the movable ends of the traction ropes 7 are detachably fixed to the corresponding pedals 4, the movable end of the upper traction rope 7 is fixed to the side wall of the upper pedal 4, and the movable end of the lower traction rope 7 is fixed to the side wall of the lower pedal 4; this paragraph of text as a whole constitutes an adjustment component for adjusting the training intensity. When the adjustment component is used, the movable ends of the two traction ropes 7 are respectively connected to the two pedals 4. When the patient performs knee flexion exercise, the pedal 4 is driven to slide along the movable plate 2. Under the action of the traction rope 7, the slider 8 is pulled to slide along the length direction of the cross bar 11. After the spring 10 is compressed and deformed, it provides a horizontal leftward thrust to the slider 8. The patient needs to overcome the thrust provided by the spring 10 to flex his knees, thereby improving the intensity of the knee flexion training; of course, the adjustment component can also be equipped with a pull ring on the side wall of the pedal 4, and a hook is installed at the movable end of the traction rope 7. The hook is clamped on the pull ring to achieve quick disassembly and assembly of the traction rope 7 and the pedal 4, which is convenient for patients to use.

[0027] When this embodiment is used, the patient lies flat on the flat plate 1, with both legs placed on the two movable plates 2 respectively and the feet located on the pedals 4. The movable plates 2 are fixed to the support plate 15 by means of a fixing assembly. When bending the knees, the pedals 4 are driven to slide along the length direction of the movable plates 2 to train the legs. According to the patient's own needs, the resistance when moving the pedals 4 can be increased by adjusting the assembly to increase the training intensity. The patient's feet can also be fixed to the pedals 4 by means of an elastic band 5, and the limit of the movable plates 2 by the fixing assembly can be released. The patient can train his legs by lifting his legs up and down. The two training methods cooperate with each other to improve the effect of leg training.

[0028] Example 2

[0029] This embodiment further illustrates the technology. Figure 1 As shown, the side walls of the movable plate 2 are fixed with limit plates 3, and the inner wall of the pedal 4 is provided with a slide groove for inserting the limit plate 3. The pedal 4 and the limit plate 3 are in sliding cooperation, and the limit plate 3 is fixed on both sides of the movable plate 2. The slide groove is provided on the inner wall of the pedal 4. The limit plate 3 is limited by the slide groove, so that the pedal 4 can only move along the length direction of the movable plate 2, preventing the pedal 4 from tilting during movement, thereby avoiding ankle injuries to the patient.

[0030] A baffle 12 is fixed to the right end of the limiting plate 3, and the baffle 12 prevents the pedal 4 from sliding off the movable plate 2, thereby improving the safety during training.

[0031] Example 3

[0032] This embodiment further illustrates the technology. Figure 1 and Figure 2As shown, an elastic band 6 is fixed on the top of the pedal 4. When the patient performs leg-lifting training, the patient holds the movable end of the elastic band 6 and lifts the legs upward, thereby exercising the patient's legs and upper limbs at the same time, thereby improving the training effect.
