Description

Technical Field

[0001] This utility model relates to the field of sports training technology, and in particular to an air resistance ankle trainer. Background Technology

[0002] The main benefits of ankle training are: firstly, enhanced stability. The ankle is a key part of the body's balance; training improves its stability and reduces the risk of sprains during sports or daily activities. Secondly, improved athletic performance. Strong ankles help improve the efficiency of movements such as jumping, running, and changing direction, enhancing overall athletic ability. Thirdly, injury prevention. Ankle training strengthens muscles, ligaments, and tendons, reducing the incidence of common sports injuries such as sprains and strains. Therefore, ankle training is crucial for athletes.

[0003] However, most existing ankle training devices use weight plates for counterweight, but these devices still have significant drawbacks: First, the resistance generated by the device is not easy to control precisely. If the resistance is too high, it cannot be used; if the resistance is too low, it will not achieve the training purpose. One has to try to adjust it back and forth, which is time-consuming and laborious. Second, when athletes train their ankles, they often need to increase the resistance to achieve the training purpose. However, the more weight plates there are, the greater the swing inertia will be. The resulting swing force is often higher than the weight of the weight plates themselves. Moreover, this swing force is unstable and uncontrollable, which will inevitably increase the load on the athlete's ankle and even cause ankle injury, which is not conducive to the athlete's safe training.

[0023] like Figure 1-5As shown, in this embodiment, an air resistance ankle trainer includes a base frame. The base frame includes two parallel longitudinal beams 1 and a crossbeam 2 connecting the two longitudinal beams 1. A fixing frame 3 is provided on the left longitudinal beam 1, and a display screen 4 is provided above the fixing frame 3. The display screen 4 is connected to the fixing frame 3 through a display screen bracket 5. A support frame 6 is provided on the right longitudinal beam 1, and a connecting beam 7 connected to the support frame 6 is horizontally provided above the crossbeam 2. The left end of the connecting beam 7 is connected to the crossbeam 2 through a support beam 8. The unit is equipped with a leg pressing mechanism. A vertical beam 9 is provided on the connecting beam 7 on the left side of the leg pressing mechanism. Handles 10 are symmetrically provided on the front and rear side walls of the upper part of the vertical beam 9. A seat 11 is provided on the connecting beam 7 on the right side of the pressing mechanism. Clamping plates 12 are symmetrically provided on the front and rear side walls of the support frame 6. The left ends of the two clamping plates 12 are connected by a rotating shaft 13. A reciprocating mechanism is symmetrically provided on the front and rear sides of the support beam 8 and is movably sleeved on the rotating shaft 13. An air supply mechanism that cooperates with the reciprocating mechanism is provided on the left side of the fixed frame 3.

[0024] Optionally, the reciprocating mechanism includes an L-shaped square beam 14, with the connecting part of the L-shaped square beam 14 facing upwards. A fixed sleeve 15 is provided at the inner end of the L-shaped square beam 14 and is movably sleeved on the rotating shaft 13. A branch pipe 16 is provided horizontally on the outer side wall of the L-shaped square beam 14, and a pedal 17 is provided on the branch pipe 16. A piston rod hinge seat 18 is provided at the connecting part of the L-shaped square beam 14. The piston rod of a cylinder 19 is movably hinged in the piston rod hinge seat 18. A cylinder seat hinge seat 20 is provided on the longitudinal beam 1 on the left side of the corresponding position of the cylinder 19, and the cylinder seat of the cylinder 19 is movably hinged in the cylinder seat hinge seat 20.

[0025] Optionally, the leg pressing mechanism includes a support sleeve 21 vertically disposed in the middle of the connecting beam 7. The lower end of the support sleeve 21 passes downward through the connecting beam 7. An adjusting beam 22 is movably engaged in the support sleeve 21. Several positioning holes 23 penetrating the adjusting beam 22 are provided on the side wall of the adjusting beam 22 from top to bottom. A locking pin 24 is provided on one side of the support sleeve 21. The locking pin 24 movably passes through the side wall of the support sleeve 212 and extends into one of the positioning holes 23 of the adjusting beam 22. Fixed shafts 25 are symmetrically provided on the front and rear sides of the upper end of the adjusting beam 22. Foam 26 is provided on both fixed shafts 25.

[0026] Optionally, a limiting beam 27 is horizontally provided within the support frame 6 at the position corresponding to the rotating shaft 13, and limiting sleeves 28 are respectively provided on the front and rear sides of the limiting beam 27, abutting against the corresponding fixed sleeve 15. The main function of the two limiting sleeves 28 is to limit the movement of the fixed sleeve 15. In addition, when the L-shaped square beam 14 rotates about the axis of the fixed sleeve 15, it can also provide some support, thereby reducing the pressure of the fixed sleeve 15 on the rotating shaft 13 and improving the service life of the device.

[0027] Optionally, the gas supply mechanism includes a base plate 29 horizontally positioned on the left side of the base frame. A bottom beam 30 connected to the left longitudinal beam 1 is located at the bottom of the base plate 29. A compressor 31 is mounted on the base plate 29 and connected to a gas supply tank 32 via pipelines. Each of the cylinders 19 is connected to the gas supply tank 32 via pipelines. A side plate 33 connected to the base plate 29 is mounted on the fixed frame 3, and a control device 34 is mounted on the side plate 33. The display screen 4 and the compressor 31 are connected to the control device 34 via wires. The gas supply tank 32 provides a gas source for the two cylinders 19. The gas pressure within the gas supply tank 32 determines the resistance generated by the cylinders 19. Furthermore, the operation of the compressor 31 can be controlled by the control device 34, thereby controlling the gas pressure within the gas supply tank 32 and adjusting the magnitude of the gas resistance generated by the cylinders 19.

[0028] Optionally, a buffer tank 35 is also provided on the base plate 29, and the buffer tank 35 is installed on the pipeline between the compressor 31 and the air supply tank 32. The compressor 31 can first compress air and inject it into the buffer tank 35. When it is necessary to increase the air resistance, the air in the buffer tank 35 can be added to the air supply tank 32, thereby increasing the air pressure in the air supply tank 32 and thus increasing the air resistance of the cylinder 19. In addition, the compressor 31 is not directly connected to the air supply tank 32, which can further improve the stability of the air pressure in the air supply tank 32.

[0029] Optionally, a sealing cover 36 is provided between the base plate 29 and the side plate 33, covering the compressor 31, the air supply tank 32, and the control device 34. The sealing cover 36 can effectively isolate the compressor 31, the air supply tank 32, and the control device 34, reducing the chance of accidental contact. In addition, the sealing cover 36 can also serve as a dustproof cover.

[0030] When using this device (which allows for single-leg or simultaneous double-leg training), the athlete sits on the seat 11 and places both feet (the balls of the feet) on the corresponding pedals 17. Then, the leg-pressing mechanism is adjusted by pulling out the locking pin 24, allowing the adjusting beam 22 to move downwards within the support sleeve 21. Once both foam pads 26 are against the thighs or knees, the locking pin 24 is reinserted into the corresponding positioning holes 23, thus fixing the foam pads 26 in place and pressing down on the legs. The athlete grips the handles 10 with both hands and then exerts downward force with the balls of their feet. The pedals 17, through the support tube 16, move the L-shaped square beam 14, causing it to rotate downwards along the axis 13 via the fixing sleeve 15. As the L-shaped square beam 14 rotates, the piston rod hinge seat 18 causes the piston rod of the cylinder 19 to contract, while the cylinder 19 provides resistance, i.e., air resistance. This effectively trains the athlete's ankles. Furthermore, after the force exerted by both feet is completed, the piston rod of the cylinder returns to its original position. However, unlike a hanging plate, it does not generate a swing force greater than its own weight. The force generated by the cylinder during the return process is linear, stable, and safe. Its reasonable structural design and convenient operation, along with its pneumatic resistance structure, make the swing force stable and controllable, thereby effectively reducing the injury to the athlete's ankle during training. It can both train and improve the ankle's bearing capacity, allowing athletes to train safely. Moreover, athletes can adjust the resistance at any time according to their own needs, saving time and effort, which is conducive to improving competitive performance and solves the problems existing in current technology.
