Description

Technical Field

[0001] This utility model relates to the field of sports training technology, and in particular to a pneumatic resistance seated leg press trainer. Background Technology

[0002] The main function of seated leg press machines is to specifically train the lower limb muscles, helping to strengthen leg muscles, improve muscle definition, and enhance lower limb stability and function. Strengthening the lower limbs helps improve performance in running, jumping, squatting, and other movements, thus improving athletes' competition results. However, most existing seated leg press machines use weight plates for counterweight, but these machines have significant drawbacks: First, the resistance generated by the device is difficult to control precisely. Too much resistance renders it unusable, while too little resistance fails to achieve the training objective, requiring constant adjustment, which is time-consuming and laborious. Second, athletes often need to continuously increase the resistance during lower limb training to achieve their goals. However, the more weight plates there are, the greater the swaying inertia, often resulting in a swaying force exceeding the weight of the plates themselves. Furthermore, this swaying force is unstable and uncontrollable, inevitably increasing the load on the athlete's lower limbs and potentially causing strains, which is detrimental to the athlete's safety during training.

[0023] like Figure 1-5 As shown in this embodiment, a pneumatic resistance seated leg press trainer includes a base frame. The base frame includes two parallel horizontal beams 1 and a longitudinal beam 2 connecting the two horizontal beams 1.

The right ends of the two support beams 6 are connected to the U-shaped beams 5, and the left ends are bent downwards and connected to the longitudinal beams 2 on the left side. The bent parts of the two support beams 6 are connected by limiting beams 7. A seat 8 is provided on the two support beams 6. A screen display 9 is provided on one side of the seat 8.

The upper end of the auxiliary beam 18 is movably connected to the auxiliary shaft 13 via an upper auxiliary sleeve 19, and its lower end is movably connected to the support shaft 3 on the left side via an lower auxiliary sleeve 20. On the support shaft 3, a connecting rod hinge seat 21 is provided in the middle of the transmission beam 15; a fixed shaft 22 is provided between the two crossbeams 1 on the side near the bottom plate 4, the fixed shaft 22 is arranged parallel to the support shaft 3, a linkage beam 23 is movably sleeved on the fixed shaft 22 through a linkage sleeve 24 provided at its lower end, a piston rod hinge seat 25 is provided on the upper part of the linkage beam 23, a cylinder seat hinge seat 26 is provided on the longitudinal beam 2 on the left side of the position corresponding to the piston rod hinge seat 25, the piston rod end of a cylinder 27 is movably hinged in the piston rod hinge seat 25, and its cylinder seat is movably hinged in the cylinder seat hinge seat 26, a connecting rod 28 is provided above the cylinder 27, the left end of the connecting rod 28 is movably hinged in the connecting rod hinge seat 21, and its right end is hinged to the piston rod hinge seat 25; the cylinder 27 is connected to the air supply mechanism through a pipeline.

[0025] Optionally, the seat 8 is movably connected to the support beam 6. A positioning plate 29 is horizontally positioned below the seat 8, connected to the limiting beam 7 and the U-shaped beam 5 respectively. Several positioning holes 30 are spaced along the length of the positioning plate 29. A base 31 is located at the bottom of the seat 8. A locking frame 32 is provided on the base 31 corresponding to the position of the positioning plate 29, and is movably engaged with the positioning plate 29. A locking pin 33 is provided on the locking frame 32, with its lower end passing through the locking frame 32 and engaging one of the positioning holes 30. Guide rods 34 are horizontally positioned on the front and rear sides of the positioning plate 29, each passing through a guide hole 35 in the base 31. Both ends of the guide rods are connected to the limiting beam 7 and the U-shaped beam 5 respectively, and the guide rods 34 are parallel to the positioning plate 29. When using the seat, the athlete can adjust its position according to their height, first pulling out the locking pin 33 to make the locking frame 32 of the base 31 and the positioning plate 29 movable. Then, push the seat 8, which moves along the guide rod 34 via the base 31. After the position is adjusted, use the locking pin 33 to pass through the frame 32 and engage it in the corresponding positioning hole 30.

[0026] Optionally, handles 36 are symmetrically provided on the front and rear sides of the seat 8. This allows athletes to grip the handles 36 with both hands when exerting force, thus maintaining a good center of gravity.

[0027] Optionally, the air supply mechanism includes a compressor 37 horizontally mounted on a base plate 4. The compressor 37 is connected to an air supply tank 38 via pipelines. Each of the cylinders 27 is also connected to the air supply tank 38 via pipelines. A control device 39 is provided on the base plate 4 at the rear of the air supply tank 38. The display screen 9 and the compressor 37 are connected to the control device 39 via wires. The air supply tank 38 provides an air source for the two cylinders 27. The air pressure in the air supply tank 38 determines the resistance generated by the cylinders 27. Furthermore, the operation of the compressor 37 can be controlled by the control device 39, thereby controlling the gas pressure in the air supply tank 38 and adjusting the magnitude of the air resistance generated by the cylinders 27.

[0028] Optionally, a buffer tank 40 is also provided on the base plate 4, and the buffer tank 40 is installed on the pipeline between the compressor 37 and the air supply tank 38. The compressor 37 can first compress air and inject it into the buffer tank 40. When it is necessary to increase the air resistance, the air in the buffer tank 40 can be added to the air supply tank 38, thereby increasing the air pressure in the air supply tank 38 and thus increasing the air resistance of the cylinder 27. In addition, the compressor 37 is not directly connected to the air supply tank 38, which can further improve the stability of the air pressure in the air supply tank 38.

[0029] Optionally, a sealing cover 41 is provided on the base plate 4 to cover the compressor 37, the air supply tank 38, and the control device 39. The sealing cover 41 can effectively isolate the compressor 37, the air supply tank 38, and the control device 39, reducing the chance of accidental contact. In addition, the sealing cover 41 can also serve as a dustproof cover.

[0030] Optionally, buffer beams 42 are provided on the limiting beams 7 corresponding to the positions of the two transmission beams 15, and buffer pads 43 are provided at the outer ends of the buffer beams 42, which movably abut against the corresponding transmission beam 15. When the transmission beam 15 is resetting, the buffer beams 42 and buffer pads 43 can not only buffer the transmission beam 15, but also ensure that the transmission beam 15 returns to its initial position.

[0031] When using this device, the athlete can sit on the seat 8, then grasp the handles 36 on both sides of the seat 8 with both hands, and step on the corresponding pedals 14 with both feet. The athlete can exert force with one foot or both feet simultaneously, pushing the pedals 14 outward. The pedals 14 move outward through the two clamps 11, the drive shaft 13, and the auxiliary shaft 14, thereby pushing the drive beam 15, which flips outward along the right support shaft 3 through the lower drive sleeve 17. Meanwhile, the auxiliary beam 18 flips outward along the left support shaft 3 through the lower auxiliary sleeve 20. The auxiliary beam 15 provides effective support for the foot pedals, preventing them from flipping due to excessive force, thus effectively protecting the athlete. As the transmission beam 15 flips outward, it pulls the connecting rod 28 through the connecting rod hinge seat 21. The connecting rod 28, in turn, pulls the piston rod hinge seat 25, thereby driving the linkage beam 23 to flip outward along the fixed shaft 22 via the linkage sleeve 24. During this flipping motion, the linkage beam 23 pushes the piston rod of the cylinder 27 inward through the piston rod hinge seat 25, continuously providing resistance as it contracts. The device features a reasonable overall structural design and convenient operation. Its pneumatic resistance structure ensures stable and controllable swing force, effectively reducing training-related injuries to the athlete's lower limbs. It achieves training goals while improving lower limb endurance, allowing for safe training. Furthermore, athletes can adjust the resistance level as needed, saving time and effort and contributing to improved athletic performance, thus solving problems existing in current technologies.
