when the device is used, when a patient needs to adjust the hanging amount of the balancing weight 230, the patient manually holds the crank connected to the left side of the second worm 690 and rotates, the shaft lever 650 rotates to drive the rotating piece 660 to rotate by means of meshing of teeth between the second worm 690 and the second worm gear 680, the corresponding second rack 630 is pulled to move rightwards by winding and rolling the second rope 670, the length of the second rope 670 is gradually adapted and lengthened from front to back, so that the shaft lever 650 can move and control the second racks 630 from front to back one by one when rotating, when the second rack 630 moves to a limit position, the corresponding outer ring 662 cannot rotate continuously, the first reed 663 and the second reed 664 are stressed and deformed, so that the inner ring 661 and the outer ring 662 can relatively rotate, and the device can control stability of each second rack 630 is guaranteed;
when the counterweight block 230 is in work, when the second rack 630 moves rightwards, the second rack 630 rotates 180 degrees through the meshing of the teeth between the second rack 630 and the outer gear ring 234, the opening position of the through groove 232 arranged in the counterweight block 230 faces downwards under the rotating action, and a patient adjusts the rotating number of the second worm 690 according to the load weight actually required, so that the quantity of the counterweight block 230 is adjusted;
when the leg weight training device works, a worker circularly treads a pedal connected to the outer side of the winding wheel 400 by using double feet, the winding wheel 400 is driven to roll through the pedal, the main cable 300 is wound, and under the winding and pulling action of the main cable 300, the weight mechanism 200 is lifted upwards to perform leg weight training;
when the cable winding device works, when the foot is stepped empty due to force release or careless operation, and the winding wheel 400 fails to wind the main cable 300, the main cable 300 reversely moves under the load of the counterweight mechanism 200, at the moment, the main cable 300 reversely moves to drive the first rack 510 fixed on the left section to move upwards, the first rack 510 drives the linkage 530 to rotate by means of tooth meshing transmission between the first rack 510 and the first gear 520, the linkage 530 is transmitted by the first gear 520, and the first worm 540 is meshed with teeth between the first worm 550 and the second worm 550 to rotate the main rotating rod 560, the two groups of main rotating rods 560 synchronously rotate relatively due to meshing reversing between the two groups of second gears 580 and connection transmission of the pulley transmission assembly 590, the two groups of friction plates 570 which are symmetrical front and back are synchronously and rotatably clamped on the outer sides of the friction blocks by driving of the main rotating rods 560, and friction braking brought by contact clamping effectively slows down the speed of the reverse movement of the main cable 300, thereby ensuring the use safety of patients;
when the exercise machine works, after the exercise is finished, the counterweight mechanism 200 resets, so that when the counterweight block 230 moves downwards and is placed above the second rack 630 again, if the load is relieved, the patient rotates the crank in the reverse direction to drive the rotating piece 660 outside the shaft rod 650 to overturn, so that the second rope 670 is loosened, under the elastic pulling action of the spring 640, the second rack 630 moves leftwards and resets, the second rack 630 is reversely rotated and reset by the meshing of the teeth, the opening of the through groove 232 is restored to be in the upper position again, and at the moment, the connection between the counterweight block 230 and the cross rod 220 is relieved, which is the whole working principle of the invention.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
