In the present invention, "left", "right", "front", "back", "top" and "bottom" refer to the orientation of the user when the apparatus is used, and "outer" and "inner" refer to the central position of the knee, i.e., the inner side near the center of the knee and the outer side far from the center of the knee. The casing 1 is designed to be hollow in the front and back, which is convenient for the wearing of the therapeutic apparatus and the movement of the legs, the casing 1 comprises a top plate and a left side plate and a right side plate, the top plate and the left side plate and the right side plate surround the cavity of the casing 1, the therapeutic apparatus is worn on the knee from the bottom of the casing 1, the two massage plates 7 are respectively positioned at the left side and the right side of the knee and are used for massaging the two sides of the knee joint, the two groups of elastic push rods 4 have the same structure and elasticity and are respectively in one-to-one correspondence with the two massage plates 7, the two groups of elastic push rods 4 respectively penetrate through the two side plates of the casing 1 in a sliding way and are used for driving the two massage plates 7 to move left and right, the massage plates 7 and the elastic push rods 4 are connected through an elastic buffer mechanism, the elastic buffer mechanism can be compressed and deformed after the stress reaches a certain degree, thereby preventing the joint from being damaged due to overlarge stress during massage, the concrete structure of the elastic buffer mechanism is explained in detail below, the elastic push rods 4 comprise push rods 401 and return springs 402, the return springs 402 are sleeved on the push rods 401 and are positioned outside the machine shell 1 and used for enabling the massage plates 7 to move towards the outside, each group of elastic push rods 4 preferably comprises two push rods 401 and return springs 402 and can improve the stability of the massage plates 7 in the moving process, two friction plates 6 are used for respectively connecting the two push rods 401 in the two groups of elastic push rods 4 on one hand and enabling the two push rods 401 to move synchronously on the other hand, one friction plate 6 is also used for being abutted against the outer side surface of the eccentric wheel 9 and driving the friction plate 6 to move when the eccentric wheel 9 rotates, the power for rotating the eccentric wheel 9 is provided by a driving motor 10, a controller 5 is fixedly installed on the machine shell 1 and used for controlling the starting and stopping of the driving motor 10, the massage speed can be properly reduced for the comfort level of massage, and therefore the driving motor 10 is preferably a speed reducing motor, the rotating speed of the eccentric wheel 9 is reduced, so that the moving speed of the massage plate 7 can be reduced, the push-pull plate 2 plays a crucial role in connection, one friction plate 6 far away from the driving motor 10 is fixedly connected with the driving motor 10 by the push-pull plate 2, the other friction plate 6 close to the driving motor 10 is in mutual extrusion fit with the eccentric wheel 9, when the eccentric wheel 9 rotates to continuously extrude the friction plate 6 matched with the eccentric wheel to the inner side, the friction plate 6 moves to the inner side, and by means of the force interactivity, the driving motor 10 is also subjected to extrusion force with the same magnitude, but the direction is opposite, the extrusion force in the opposite direction is changed into the pulling force for pulling the driving motor 10 to the outer side, the driving motor 10 transmits the pulling force to the friction plate 6 far away from the driving motor 10 through the push-pull plate 2, so as to pull the friction plate 6 far away from the driving motor 10 to the inner side for the same distance, furthermore, the synchronous opposite movement of the two friction plates 6 is realized, namely the two massage plates 7 move synchronously and oppositely, because the therapeutic apparatus is worn on the knee for use, when the therapeutic apparatus is worn on the knee, the force balance principle is utilized, even if the knee is not positioned between the two massage plates 7, the therapeutic apparatus is stable and balanced when in use, and no matter which one of the two massage plates 7 contacts the knee joint firstly during massage, the position of the therapeutic apparatus can be automatically adjusted before the first massage period, so that the knee is centered between the two massage plates 7, and when the force is really applied for massage, the two massage plates 7 can simultaneously extrude the left side and the right side of the knee. The invention provides a comprehensive therapeutic apparatus for knee osteoarthritis, which has the working principle that firstly the therapeutic apparatus is worn on the knee and is fixed relative to the knee (the fixing mode can be realized by a magic tape, other more preferable modes can also be adopted, and the detailed description is provided below), then a driving motor 10 is started to drive an eccentric wheel 9 to rotate, the eccentric wheel 9 continuously extrudes a friction plate 6 matched with the eccentric wheel inwards in the rotating process, the friction plate 6 moves inwards after being extruded, the elastic push rod 4 drives a massage plate 7 corresponding to the eccentric wheel to move inwards, meanwhile, the eccentric wheel 9 is applied with the acting force with the same size and opposite direction, so that the driving motor 10 drives a push-pull plate 2 to move outwards, the friction plate 6 far away from the driving motor 10 moves inwards, the friction plate 6 drives another massage plate 7 to move inwards through the elastic push rod 4 corresponding to the friction plate 6, the time that two massage boards 7 moved to the inboard is the same, and the distance is the same, realizes the synchronous motion to extrude articular both sides simultaneously, massage the joint, when the massage dynamics is too big, be greater than the maximum force that elastic buffer mechanism can bear, elastic buffer mechanism atress compressive deformation makes two massage boards 7 move to the outside simultaneously, protection when realizing massaging the joint prevents the joint damage. In the prior art, two motors are arranged and respectively positioned at the left side and the right side of the knee, the two motors are started to respectively drive the cams connected with the motors to rotate, and the rotation of the cams drives the massage plate provided with the massage teeth to move left and right, so that the two sides of the knee are massaged. The prior art has the disadvantages that although the synchronous starting, closing and rotating speed of the two motors can be consistent in a control layer, on a transmission path, because the placing positions of knees are difficult to be the same, when massage is realized, the motion amplitudes of the two transmission components cannot be completely consistent, that is, two groups of cams on two sides cannot be guaranteed to extrude the opposite two sides of a joint with the highest point, the two motors cannot realize the accurate matching, so that the stress time and the stress size on two sides of the joint are different, and the massage effect is poor. The main innovation point of the invention is that the massage to the left and right sides of the knee joint can be realized by only using one motor by utilizing the principle of force interaction, and the two massage plates 7 can realize synchronous and same-force massage, so that the massage effect is better.

In this embodiment, by providing the push-pull plate 2 slidably connected to the housing 1, and by arranging one end of the push-pull plate 2 fixedly connected to one of the friction plates 6 and the other end thereof cooperating with the other friction plate 6 through the driving motor 10 and the eccentric wheel 9, when the driving motor 10 drives the eccentric wheel 9 to rotate, and further the eccentric wheel 9 presses one of the friction plates 6 to move, the corresponding elastic push rod 4 is compressed and deformed, and the elastic push rod 4 further pushes the corresponding massage plate 6 to move inward, because the two groups of elastic push rods 4 respectively connected to the two friction plates 6 have the same elasticity, the application of force is mutual, so that the other group of elastic push rods 4 are also compressed and deformed to the same extent, that is, the moving distances of the two groups of elastic push rods 4 are the same, and thus the moving distances of the two massage plates 7 are the same, and one driving motor 10 can simultaneously drive the two massage plates 7 to move synchronously and oppositely, the massage to the two sides of the knee is realized. Compared with the prior art, the driving motor 10 can replace the functions of two motors in the prior art, the interaction of force is utilized, the motion amplitude of the whole transmission assembly can be accurately the same, when in massage, the therapeutic apparatus is wearable, when the therapeutic apparatus is worn, no matter the knee position is in the middle of the two massage plates 7 and deviates from the left side or the right side, when any one massage plate 7 is firstly abutted to the knee joint, the position of the therapeutic apparatus can be automatically adjusted for self balance, so that the two massage plates 7 on two sides can simultaneously press the two opposite sides of the joint with the same force, the matching of the two motors is not needed, the massage effect is better, and the defects in the prior art can be effectively overcome.

In this embodiment, the elastic buffer mechanism includes a vertical plate 3 fixedly connected with the elastic push rod 4 and a first telescopic rod 23 fixedly connected with the massage plate 7, the other end of the first telescopic rod 23 is fixedly connected with the vertical plate 3, the number of the first telescopic rods 23 may be one or more, the first telescopic rods 23 are used for providing a moving space for the massage plate 7 to move towards the outside, the first telescopic rods 23 are sleeved with compression springs 25, the compression springs 25 are always in a compression state, so that the two massage plates 7 are always in a stable state.

Furthermore, an adjustable limiting mechanism is arranged on the push-pull plate 2, and the limiting mechanism limits the push-pull plate 2 in a one-way mode to limit the maximum distance between the two massage air bags 22, so that the two massage air bags 22 wrap the two sides of the joint to fix the therapeutic apparatus with the joint. When massage is performed, along with the extrusion of the massage airbag 22 to the knee joint, after the two sides of the knee joint are completely wrapped and reach a certain compactness (namely, when the therapeutic apparatus and the knee joint can be relatively fixed), before the massage teeth 703 contact the knee joint, the operation of the driving motor 10 is stopped, at this time, the push-pull plate 2 is limited by adjusting the limiting mechanism, and the limiting direction is the opposite direction of the moving direction of the push-pull plate 2, so that after the massage teeth 703 finish the first extrusion to the knee joint, the massage teeth 703 and the massage airbag 22 do not return to the far position, but return to the positions where the massage airbag 22 wraps the two sides of the knee joint, and therefore, in the massage of the later period, the massage airbag 22 can wrap the knee joint all the time, namely, the therapeutic apparatus and the knee joint are always in a relatively fixed state. The therapeutic apparatus can be relatively fixed with the knee through the matching of the massage air bag 22 and the limiting mechanism, an additional fixing mechanism is not needed, the therapeutic apparatus is fixed in the massage process, the fixing mode is obviously more convenient and faster, the size of the therapeutic apparatus is reduced, and the therapeutic apparatus is convenient to carry; and when the two massage air bags 22 extrude the two sides of the knee joint, in the process, the mutual effect of the forces is utilized, in order to achieve the balance of the therapeutic apparatus, when the two massage air bags 22 are fixed, the forces of the two massage air bags 22 extruding the two sides of the knee joint can reach the same magnitude, and the specifications and the stress magnitudes of the two massage air bags 22 are completely the same, so that when the fixation with the knee is completed, the distance from the two massage plates 7 to both sides of the knee is the same, namely, the centering of the knee between the two massage plates 7 is automatically completed, so that the therapeutic apparatus is ensured to be safer and more effective, when the therapeutic apparatus is worn, no matter whether the knee position is in the middle of the two massage plates 7 or deviates from the left side or the right side, when any massage plate 7 is firstly abutted against the knee joint, the therapeutic apparatus can automatically adjust the position for self balance, so that the two massage plates 7 on the two sides simultaneously press the two opposite sides of the knee joint with the same force.

The rotating rod 14 can be rotated to drive the adjusting screw tube 15 to rotate along with the rotating rod, and the rotating adjusting screw tube 15 can drive the two abutting rods 13 to rotate in the same direction by utilizing the mutually meshed strip-shaped teeth, so that the synchronous adjustment of the two abutting rods 13 can be realized. By the adjusting mode, the two abutting rods 13 can be adjusted in a time-saving manner, and the adjusting efficiency is higher; moreover, the two abutting rods 13 can be synchronously adjusted, the adjusting effect is better, and the situation that one abutting rod 13 abuts against the side surface of the opening 101 and one abutting rod 13 does not abut against the side surface of the opening 101 can be avoided; furthermore, the engagement fit between the adjusting screw tube 15 and the two abutting rods 13 is utilized to realize the limiting effect of the adjusting screw tube 15 on the two abutting rods 13, and when the adjusting screw tube 15 is rotated without external force, the two abutting rods 13 are difficult to complete automatic rotation, so that the situation that the limiting mechanism fails to limit the push-pull plate 2 is difficult to occur in the massage process.
