[0003] After retrieval

[0004] An orthopedic joint exercise device, publication number: CN214763102U. In actual use, the patient sits on the seat board and then steps both feet on the two ends of the seesaw. By alternating the two feet and with the cooperation of the connecting spring, the patient's legs can be effectively exercised. When the position of the seat assembly needs to be adjusted, it is only necessary to rotate the adjustment bolt by rotating the handle, so that under the action of the thread of the threaded sleeve, the seat assembly above the threaded sleeve is driven to move. Therefore, it can be suitable for patients with different leg lengths.

[0005] However, when the existing technology is in use, it relies on the elastic expansion and contraction of the spring to assist the person in exercising, and the spring of the existing technology is fixed on the seesaw and the base. Therefore, when the person is exercising, the degree of contraction of the spring is fixed. As a result, when exercising, after the person steps on the spring until it is fully elastically contracted, the relative position of the seesaw and the base cannot be adjusted again. Therefore, the person cannot increase the intensity of the training. That is, when the existing technology is used, the training intensity that the person can generate is limited.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-4As shown, an orthopedic joint exercise device includes a base plate 2, on which two spring plates 1 are symmetrically provided. The swinging edges of the two spring plates 1 are close to each other, and a pedal 4 is provided between the swinging edges of the two spring plates 1, which is raised and lowered relative to the base plate 2. The swinging edges of the two spring plates 1 are provided with grooves facing each other. Connecting plates 5 that match the grooves of the spring plates 1 are fixed to both sides of the pedal 4. The pedal 4 is slidably connected to the base plate 2 via a support assembly. When the pedal 4 is subjected to downward pressure and the support assembly slides along the base plate 2, the two spring plates 1 are synchronously driven to elastically move downward, and at the same time, the connecting plates 5 slide in the grooves of the spring plates 1:

[0025] The support assembly includes front and rear diagonal struts 8 respectively arranged on both sides of the bottom edge of the pedal 4. The lower end of each diagonal strut 8 is rotatably connected to the upper end of the block 12. The lower end of the block 12 is slidably placed in the corresponding slide 14 on the pad 2, and the block 12 is connected to one end of a spring 13 in the slide 14. The other end of the spring 13 is fixed to the slide 14. When the pedal 4 is forced to drive the diagonal strut 8 downward and push the block 12 to slide along the slide 14, the spring 13 is stretched. When the pedal 4 is released from the force, the block 12 returns to its original position under the action of the spring 13 and the diagonal strut 8 is propped up. Therefore, under the dual action of the spring 13 and the shrapnel 1, the downward pressure resistance of the pedal 4 is increased, thereby enhancing the exercise intensity.

[0026] Three slide grooves 14 are provided on the base plate 2, which are longitudinally and parallelly distributed on the base plate 2. Two side slide grooves 14 are symmetrically provided with two blocks 12 with opposite sliding directions and two corresponding springs 13. A central slide groove 14 is provided with a screw 15 with opposite thread directions at both ends.

[0027] The pad 2 is also slidably connected to a horizontal support rod 7 that is slidably matched with the bottom surface of the spring piece 1. The horizontal support rod 7 slides along the length direction of the spring piece 1 in the initial state, so that the horizontal support rod 7 contacts the bottom surface of the spring piece 1 at different positions, that is, with the horizontal support rod 7 as the fulcrum, the length of the force arm between the horizontal support rod 7 and the swinging edge of the spring piece 1 can be adjusted by adjusting the position of the horizontal support rod 7. The longer the force arm, the smaller the force required by the pedal 4 to swing the spring piece 1, and the shorter the force arm, the greater the pressure required to move the pedal 4 downward. Therefore, the elastic force of the swinging edge of the spring piece 1 can be further adjusted by setting the horizontal support rod 7, that is, the downward pressure resistance of the pedal 4 can be further adjusted.

[0028] The horizontal support rod 7 is displaced by the following driving mechanism: a screw 15 is connected to the slide groove 14 in the middle of the pad 2, and the screw 15 is connected to the motor installed on the side of the pad 2. The two ends of the screw 15 are respectively screwed with corresponding slides 6. The distance between the two slides 6 is adjusted by rotating the screw 15, so that the two slides 6 are close to or away from each other. A horizontal rod parallel to the horizontal support rod 7 is provided on the slide 6. The two ends of the horizontal rod are respectively connected to the fixed ends of the corresponding electric telescopic rod 16. The telescopic end of the electric telescopic rod 16 is fixed on the horizontal support rod 7. The electric telescopic rod 16 is fixedly connected to the mounting seat 9. The mounting seat 9 has lower swing arms 10 hinged on both sides. The swing end of the lower swing arm 10 is hinged to the lower end of the upper swing arm 11, and the upper end of the upper swing arm 11 is movably connected to the support rod 7. When the slide 6 moves, it drives the electric telescopic rod 16 and the horizontal support rod 7 to move on the bottom surface of the spring piece 1. In addition, in order to prevent the horizontal support rod 7 from generating an upward thrust on the spring piece 1 or detaching from the bottom surface of the spring piece 1 during the movement, the height of the horizontal support rod 7 can be adjusted by extending and contracting the electric telescopic rod 16, thereby ensuring that the horizontal support rod 7 fits the bottom surface of the spring piece 1 without generating pressure on the spring piece 1. The mounting base 9, the upper swing arm 10 and the lower swing arm 11 provided on the electric telescopic rod 16 can prevent the horizontal support rod 7 from bending and deformation.

[0029] In addition: there is at least one pad 2, and the pad 2 is fixedly connected to the anti-slip strip 3 with a hollow surface. The anti-slip strip 3 can ensure that the position of the device is fixed when in use, and the hollow surface can be used to fix the pad 2 to the side of the bed by bolts or ropes, which is convenient for exercise.

[0030] The notches of the grooves facing each other for the swinging edges of the spring piece 1 are provided with baffles, which are inserted into the through grooves of the connecting plates 5 on both sides of the pedal 4 so that the swinging edge of the spring piece 1 can move relative to the connecting plates 5, and at the same time, the swinging edge of the spring piece 1 is connected to the connecting plates 5 through the baffles.

[0031] Working principle: According to the actual situation of the exerciser, the installation position of the pad 2 is selected. When in use, the exerciser's foot steps on the pedal 4, so that the pedal 4 overcomes the elastic force of the spring 13 and the spring 1 and moves toward the pad 2, and according to the training effect and recovery situation, by rotating the screw 15, the slide 6 drives the horizontal support rod 7 to move, which is used to adjust the distance between the horizontal support rod 7 and the swing end of the spring 1, and then adjust the resistance of the spring 1 to the downward swing, and finally adjust the downward pressure resistance of the pedal 4.

[0032] The wiring diagram of the motor and the electric telescopic rod 16 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the motor and the electric telescopic rod 16 are not explained in detail.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
