[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 A combined physical training device includes a support beam 1, with a C-shaped base frame 2 bolted to one end of the support beam 1. A diagonal rod 3 is welded to the lower surface of the support beam 1 near the other end. A T-shaped base frame 4 is bolted to the bottom end of the diagonal rod 3. A seat support 5 is bolted to the upper surface of the support beam 1, and a seat cushion 6 is bolted to the top surface of the seat support 5. Vertical support rods 7 are bolted to both sides of the support beam 1. A horizontal arm 8 is bolted to the top of the vertical support rod 7. A top plate 9 is welded to one end of the horizontal arm 8. A bare rod 10 is bolted to the lower surface of the top plate 9. A counterweight 11 is slidably connected to the outer surface of the bare rod 10. A backrest 12 is bolted to the outer surface of the vertical support rod 7. A suspension rod 13 is inserted inside the counterweight 11, and a fixed connection is made to the top of the suspension rod 13. The lifting ring 14 has a fixing bolt 15 threadedly connected to the outer surface of the lifting rod 13. A first steel wire rope 16 is tied inside the lifting ring 14. A slider 17 is slidably connected to the outer surface of the first steel wire rope 16. A second steel wire rope 18 is fixedly connected to the bottom end of the slider 17. A pull rod 19 is tied to one end of the first steel wire rope 16. A limit tube 20 is connected to one end of the second steel wire rope 18. A third steel wire rope 21 is fixedly connected to one end of the limit tube 20. A pull ring 22 is fixedly connected to one end of the third steel wire rope 21. A first pulley 23 is installed at one end of the cross arm 8. A second pulley 24 is installed on the upper surface of the cross arm 8 near the other end. A third pulley 25 is installed on the lower surface of the support beam 1. A short rod 26 is hinged to one end of the support beam 1. Lifting rods 27 are fixedly connected to both sides of the short rod 26 near the bottom.
[0023] Specifically, the outer surface of the first wire rope 16 slides in contact with the first pulley 23 and the second pulley 24, and a hole is provided through the center of the top surface of the top plate 9 for the first wire rope 16 to pass through.
[0024] The advantage is that when the exerciser sits on the seat cushion 6, the backrest 12 allows for easy support. When the exerciser pulls the lever 19, it pulls the first steel wire rope 16. With the assistance of the first pulley 23 and the second pulley 24, the first steel wire rope 16 pulls the hanging ring 14 upward. The hanging ring 14 drives the hanging rod 13, which in turn drives the counterweight 11 upward. When the lever 19 is released, the counterweight 11 automatically falls down along the two bare rods 10 under the action of gravity. This reciprocating motion can exercise the exerciser's arms and back.
[0025] Specifically, the outer surface of the second wire rope 18 slides in contact with the third pulley 25, and the outer surfaces of the short rod 26 and the diagonal rod 3 are provided with holes through which the second wire rope 18 can pass.
[0026] The advantage is that when the exerciser's calf contacts the outer surface of the lifting bar 27, the leg exerts force, causing the lifting bar 27 to rotate around the axis connecting it to the support beam 1. Because the limiting tube 20 abuts against the outer surface of the short rod 26, the leg exertion pulls the second steel cable 18, which, with the assistance of the third pulley 25, pulls the slider 17. The slider 17 pulls the first steel cable 16. Because a limiting plate is set on the outer surface of the pull rod 19, the slider 17 pulls the first steel cable 16. The No. 16 steel wire rope drives the lifting ring 14, the lifting rod 13 and the counterweight 11 to rise. After the legs relax, the counterweight 11 automatically falls back. This reciprocating motion can exercise the legs. When the person is not sitting on the seat cushion 6, the pull ring 22 can be pulled to pull the No. 3 steel wire rope 21. The No. 3 steel wire rope 21 pulls the limit tube 20, which in turn drives the No. 2 steel wire rope 18. In this way, the counterweight 11 is finally raised, which allows the person to exercise their hands in a standing position.
[0027] Specifically, a limit plate is fixedly connected to the outer surface of the pull rod 19, and a No. 3 steel wire rope 21 is fixedly connected between the pull ring 22 and the limit tube 20.
[0028] Specifically, the lifting rod 27 includes a sponge sleeve on its outer surface, and the lower surfaces of the C-shaped base 2 and the T-shaped base 4 are threaded with foot pads.
[0029] Specifically, the upper surface of the counterweight 11 has two round holes and one square hole. The smooth rod 10 is inserted into the two round holes, and the hanging rod 13 is inserted into the square hole. The outer surface of the hanging rod 13 has five screw holes at equal intervals. The screw holes are used for threaded connection with the fixing bolt 15. The counterweight 11 is provided with five screw holes.
[0030] The advantage is that by setting five counterweights 11, each weighing five kilograms, when the fixing bolt 15 is rotated to disengage from one of the screw holes of the hanging rod 13, if a five-kilogram counterweight is needed, the fixing bolt 15 is inserted into the side hole of the topmost counterweight 11, and then the fixing bolt 15 is connected to the pull rod 19. In this way, during exercise, the hanging rod 13 will only drive one counterweight 11 to rise. If the number of counterweights 11 needs to be adjusted, the fixing bolt 15 only needs to be reconnected to the screw hole on the outer surface of the pull rod 19. The overall structure makes it easy to adjust the counterweight weight during exercise.
[0031] In use, the exerciser first sits on the seat cushion 6 with their back against the backrest 12. To exercise the arms and back, the exerciser pulls the lever 19, pulling the first steel wire rope 16. With the assistance of the first pulley 23 and the second pulley 24, the ring 14, the rod 13, and the counterweight 11 rise. After releasing the lever 19, the counterweight 11 falls down along the bare rod 10 under gravity, and this process is repeated. To exercise the legs, the exerciser places their lower leg in contact with the lifting rod 27, and uses their leg strength to lift the lifting rod 27 around the axis connecting it to the support beam 1. Because the limiting tube 20 abuts against the short rod 26, the leg strength pulls the second steel wire rope 18. With the assistance of pulley 25, the slider 17 is driven, which in turn pulls the wire rope 16. Due to the limit plate on the outside of the lever 19, the wire rope 16 drives the lifting ring 14, the lifting rod 13 and the counterweight 11 to rise. After the legs are relaxed, the counterweight 11 falls back down, and so on. If the weight of the counterweight needs to be adjusted, each counterweight 11 weighs five pounds. Rotate the fixing bolt 15 to disengage it from the screw hole of the lifting rod 13. If five pounds of counterweight is required, insert the fixing bolt 15 into the side hole of the top counterweight 11 and then connect it to the lever 19. If the number of counterweights 11 needs to be adjusted, simply reconnect the fixing bolt 15 to the screw hole on the outer surface of the lever 19.
