[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figure 1-Figure 3The utility model provides an embodiment of a joint rehabilitation device for leg treatment, comprising a frame 1, the top of the frame 1 is detachably connected to a mounting frame 2, the inner wall of the mounting frame 2 is fixedly connected to a shell 8, the inner wall of the shell 8 is rotatably connected to a connecting rod 9, a driving motor can make the connecting rod 9 rotate, and the end of the connecting rod 9 is rotatably connected to a pedal 10, and the rotation of the connecting rod 9 drives the pedal 10 to make a circular motion. A tearing tape is provided on the pedal 10 to fix the foot to prevent it from falling off, and with the circular motion of the pedal 10, the knee is bent to achieve the effect of leg treatment, and the top of the frame 1 is fixedly connected to a columnar block 3, the inner wall of the mounting frame 2 is provided with a circular groove 7, the outer wall of the columnar block 3 is plugged into the inner wall of the circular groove 7, and the mounting frame 2 and the frame 1 can be connected together by aligning the columnar block 3 with the circular groove 7 and inserting it. The inner wall of the columnar block 3 is slidably connected to a pull rod 4, and the inner wall of the pull rod 4 is slidably connected to two groups of card blocks 5, and the interval between the two groups of card blocks 5 is reset When the cam 5 is in the closed position, the cam 5 is in the closed position, and the cam 5 is in the closed position, so that the cam 5 is in the closed position and the cam 5 is in the closed position, so that the cam 5 can not be ejected.
[0032] Reference Figure 1 and Figure 4The inner wall of the frame 1 is slidably connected to a telescopic frame 11, and the inner wall of the telescopic frame 11 is slidably connected to a pressing block 12. The outer wall of the pressing block 12 is slidably connected to the inner wall of the frame 1. The interval between the two groups of pressing blocks 12 is elastically connected by a return spring b14. The two ends of the return spring b14 are respectively fixedly connected to the inner end of the two groups of pressing blocks 12. Pressing the pressing blocks 12 inward can make them squeeze each other and move the return spring b14 inward. At the same time, the elastic force generated by the deformation of the return spring b14 gives the pressing block 12 a reverse thrust, prompting it to reset. The inner wall of the pressing block 12 is slidably connected to a guide rod 13 to ensure that the two groups of pressing blocks 12 will not deviate during the movement, and it also effectively prevents the return spring b14 from collapsing. The outer wall of the pressing block 12 is fixedly connected with a buckle assembly, which includes a limit The positioning block 15, the outer wall of the limit block 15 is fixedly connected to the outer wall of the pressing block 12, and pressing the pressing block 12 inward can drive the limit block 15 to move inward together. A plurality of groups of limit grooves 16 are provided on the inner wall of the telescopic frame 11, and the outer wall of the limit block 15 is engaged with the inner wall of the limit groove 16. After the limit block 15 moves inward until it is disengaged from the limit groove 16, the telescopic frame 11 can be dragged outward or inward. At this time, the pressing block 12 slides along the inner wall of the telescopic frame 11. When the telescopic frame 11 needs to be fixed, the pressing block 12 is released, and the reset spring b14 pushes the two groups of pressing blocks 12 to reset, and at the same time drives the limit block 15 to be engaged in the limit groove 16, fixing the position of the telescopic frame 11. The bottom end of the telescopic frame 11 is fixedly connected to a support seat 17, and the support seat 17 is placed on the ground to support the entire device.
[0033] Working principle: Place the foot on the pedal 10, fix the foot with the tear tape, drive the motor to drive the connecting rod 9 to rotate, thereby driving the two sets of pedals 10 to do circular motion, so that the patient's knees are bent, which has a therapeutic effect on the joints. When adjusting the height of the device according to the patient's position or height, press the two sets of pressing blocks 12 inward to drive the limit blocks 15 to squeeze the return spring b14 inward. After releasing the clamping connection with the limit slot 16, the telescopic frame 11 can be dragged out or dragged back into the frame 1 to adjust the height. The overall height of the device allows the patient to perform leg treatment in the most comfortable posture. When the device needs to be disassembled and transported, the two groups of blocks 5 are pressed inward while the pull rod 4 is pulled outward so that the blocks 5 are completely retracted and pressed against the inner wall of the columnar block 3 so that they cannot pop out. At this time, the mounting frame 2 can be removed. The disassembly method is simple and convenient for transportation. The assembly is also relatively convenient. The circular groove 7 of the mounting frame 2 can be directly aligned with the columnar block 3 and put on. The inner wall of the circular groove 7 squeezes the inclined surface of the block 5 to retract it. After it is fully put on, the block 5 pops out to fix the mounting frame 2.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
