[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention, the technical solution in the embodiments of the present invention will be described clearly and completely, it is clear that the embodiments described are only a part of the embodiment of the present invention, not all embodiments. Based on embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work, are within the scope of protection of the present invention.

[0028] See Figure 1-Figure 6 As shown, the present invention provides the following technical solutions: a rheumatic immunology knee rehabilitation apparatus, comprising a base plate 1, an ankle fixing component, a lateral training component and a moving component, the upper wall of the base plate 1 is provided with a stool 2, the front surface wall of the stool 2 is concave to form a second groove 19, the interior of the second groove 19 is provided with an articulate seat 20, the articulation seat 20 is articulated on the articulation plate 7, and the upper and lower ends of the articulate seat 20 are fixed finite slider 21, The inner and upper walls of the second groove 19 are provided with a limit groove 23 adapted to the limit slider 21, the outer wall of the limit slider 21 is provided with a first screw hole 22, the inner wall of the limit groove 23 is provided with a second screw hole 24, the side wall of the stool 2 is screwed with fastening screw 8, the fastening screw 8 runs through the first screw hole 22 and screws the inner wall connected to the second screw hole 24, the two side walls of the articulated plate 7 are fixed with a second hanging ring 6, and the upper end of both sides of the wall of the stool 2 is fixed with the first hanging ring 4, Ipsilateral first ring 4 and second ring 6 is connected to the tension spring 5, the ankle fixing assembly is located on the articulated plate 7, and the ankle fixing component is used to fix the ankle of the trainer, specifically, during training, the ankle fixation component is used to fix the ankle, and then the ankle is applied downward, so that the articulation plate 7 rotates around the articulation seat 20, at this time the tension 5 is stretched, resulting in the opposite direction of the pull, and then can effectively carry out calf strength training and knee joint flexion and extension training, with lateral training, The training effect is better, in addition, when performing lateral training, you can manually remove the pull spring 5 between the first ring 4 and the second ring 6, and then push the articulation plate 7 inside, using the limit slider 21 to slide in the limit chute 23, the articulated seat 20 is moved to the inner bottom of the second groove 19, you can make the articulated plate 7 retracted into the second groove 19, and then screw the tightening screw 8 for the limit, which can effectively avoid the articulation plate 7 pairs of lateral training blocking, the lateral training component for the foot forward force, To achieve flexion and extension of the knee joint, the moving component is used to change the spacing between the lateral training component and the stool 2.

[0029] Further, the ankle fixing component comprises an ankle fixing slot 15 and a limit bar 27, the ankle fixing slot 15 has two, two ankle fixation slots 15 symmetrically opened at the end of the articulation plate 7, the limit lever 27 runs through the outer port of the ankle fixing slot 15, when calf and knee training is required, the ankle may be placed within the ankle fixing slot 15, and then the upper limit rod 27 blocks the outer port of the ankle fixing slot 15, which can effectively limit the fixation of the ankle.

[0030] Further, the lateral training components include a fixing block 12, pedal 13, elastic strap 14, spring 17 and a connecting rod 18, the side wall of the fixing block 12 is opened with a first groove 16, one end of the spring 17 is connected to the inner bottom of the first groove 16, the connecting rod 18 is connected to the other end of the spring 17, the pedal 13 is connected to the end of the connecting rod 18 away from the spring 17, the elastic strap 14 is mounted on the side of the pedal 13 towards the fixing block 12, during lateral training, the trainer may sit on a stool 2, Then the sole of the foot on the pedal 13, and then the use of elastic straps 14 to tie the foot for fixation, and then the foot forcefully extended forward, the spring 17 in the first groove 16 stretched, the leg straightened and then retracted, and reciprocating, can achieve knee joint flexion and extension training and thigh strength training.

[0031] Further, the moving assembly comprises a support block 9, a T-type slider 10 and a limit pin 11, the support block 9 is fixed to the bottom end of the fixed block 12, the T-type slider 10 is symmetrically connected to the bottom end of the support block 9, the upper wall of the bottom plate 1 is provided with a T-type chute 25 adapted to the T-type slider 10, the bottom plate 1 is on the upper wall and is located on both sides of the T-type chute 25 equal spacing to open a limited position hole 26, the limit pin 11 inserts the inside of the limit hole 26, the outer wall of the T-shaped slider 10 is also equally spaced with a through hole, Limit pin 11 through the T-type slider 10, when it is necessary to adjust the spacing between the support block 9 and the stool 2, the limit pin 11 may be removed first, and then the use of the T type slider 10 in the T-type chute 25 to move the support block 9, after changing to the appropriate spacing, and then insert the limit pin 11 into the limit hole 26 for the limit, the spacing change is convenient and fast.

[0032] Further, the lower end of the wall on both sides of the stool 2 is opened with a storage slot 3, the inner bottom of the storage slot 3 is opened with a shallow slot, the removed spring 5 can be stored in the storage slot 3, more convenient, secondly, the storage slot 3 can also store tools and the like.

[0033] Further, the outer wall end of the limit rod 27 is provided with an external thread, and the outer end of the limit rod 27 is screwed with a nut, after the limit bar 27 blocks the external port of the ankle fixing slot 15, the nut may be screwed to avoid sliding out of the limit rod 27.

[0034] Further, the inner surface wall of the ankle fixing groove 15 and the outer surface of the limit bar 27 are glued with a soft pad, the inner surface wall of the soft pad is smooth without bulging, the pad touches the ankle, which can effectively increase comfort and reduce the crush injury of the ankle.

[0035] Further, the bottom end of the bottom plate 1 is fixed with an anti-slip pad, the lower wall of the anti-slip pad is provided with a non-slip pattern, and the anti-slip pad with a slip pattern is opened to contact the ground, which can increase the friction and is not easy to move.

[0036] Further, the upper surface wall of the base plate 1 is opened near the four corners of the mounting hole, the mounting hole is a circular structure, the bolt through the base plate 1 with a mounting hole, can further increase the stability of the device, to avoid slippage.

[0037] Further, the side wall of the support block 9 is equipped with a grip, the height of the upper end surface of the fixing block 12 does not exceed the height of the seat 2 riding surface, when moving the support block 9, the grip grip is convenient for the hand to exert force, more convenient, in addition, the fixing block 12 is used to place the legs, the upper end surface is too high will affect the comfort.

[0038] Although embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it will be understood that without departing from the principles and spirit of the present invention may be various variations, modifications, substitutions and variants of these embodiments, the scope of the present invention is limited by the appended claims and their equivalents.
