Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a standing leg stretching device. Background Art

[0002] The standing leg stretching device, also known as a standing incline board, is a common training device in gyms, primarily used for ankle correction and lower limb rehabilitation. By adjusting the incline angle, it allows the user to use their own weight to stretch while standing, achieving rehabilitation goals. This device typically consists of a support board, a fixed frame, and an angle adjustment frame. Adjustable inclination angles allow for different levels of inclination, making it suitable for conditions such as foot drop, Achilles tendon contracture, inversion, and valgus foot control disorders.

[0003] The main benefits of the standing incline board include: through slow stretching exercises, using body weight to help maintain ankle range of motion and muscle length, improving the muscle properties of the triceps surae, reducing muscle tension, and alleviating patients' problems such as excessive muscle tension and correcting foot drop and inversion deformities. It can also prevent varicose veins in the lower limbs and help restore lower limb function.

[0004] When using a standing incline board, it's important to keep the following in mind: First, choosing the right incline board is crucial. For patients with limited mobility, a sturdy metal support is recommended for safety. Second, keep your feet shoulder-width apart when using it. You can lean against a wall or use the handrails for balance. Finally, standing incline board training should be practiced consistently for optimal rehabilitation results.

[0005] The existing leg stretching devices on the market have a simple structure and require bending over to adjust a fixed angle before use. During use, the angle of the foot pedal cannot be adjusted and cannot be moved after adjustment, which is inconvenient to use and has a poor stretching effect. Utility Model Content

[0038] like Figure 1-7As shown, the utility model discloses a standing leg stretching device, which includes a base plate 1, a footrest 2, an arc-shaped space 3, an arc-shaped bar 4, a control frame 5, and a hydraulic adjustment unit 6. The footrest 2 is rotatably connected to the base plate 1, and the arc-shaped bar 4 is provided below the footrest 2. The base plate 1 defines an arc-shaped space 3, and the arc-shaped bar 4 is slidably connected to the arc-shaped space 3. The base plate 1 is provided with a control frame 5, and the control frame 5 is provided with a hydraulic adjustment unit 6. The hydraulic adjustment unit 6 can control the rotation of the footrest 2. The hydraulic adjustment unit 6 includes a control line 7 provided in the control frame 5, the control line 7 is filled with liquid and is connected to the arc-shaped space 3. The hydraulic adjustment unit 6 includes an initial adjustment unit 8 and a grip adjustment unit 9. The initial adjustment unit 8 includes an initial adjustment tube 10 disposed within the control frame 5. The initial adjustment tube 10 is connected to the control line 7. An initial adjustment plate 11 is movably connected to the initial adjustment plate 11. The initial adjustment plate 11 is connected to a rotating plate 12. The rotating plate 12 is provided with a thread 13. The control frame 5 is provided with an initial adjustment hole 14. The initial adjustment hole 14 is provided with a thread 13. The rotating plate 12 is provided with a handle 15. The grip adjustment unit 9 includes a connecting tube 16 disposed within the control frame 5. The connecting tube 16 is connected to the control line 7. The end of the connecting tube 16 away from the control line 7 is provided with a grip adjustment tube 17. A plurality of sliders 18 are slidably connected to the grip adjustment tube 17. The grip adjustment tube 17 is wrapped with an annular cushion 19 with anti-slip grooves.

[0039] Before use, the footrest 2 angle can be adjusted using the initial adjustment unit 8, eliminating the need to bend over. Standing on the footrest 2, gripping the grip adjustment unit 9 with one or both hands allows the footrest 2 to be moved up and down slightly, optimizing the stretching effect on the hamstrings. This also allows for increased grip strength during use.

[0040] Optionally, a liquid inlet 20 is provided above the control line 7, and a cover is provided on the liquid inlet 20. This can facilitate filling and replacing the liquid in the control line 7.

[0041] Optionally, a waterproof plate 21 is slidably connected in the arc space 3, and an abutting roller 22 is provided between the waterproof plate 21 and the arc strip 4. This can prevent the liquid in the control line 7 from overflowing from the foot pedal 2.

[0042] Optionally, a drain port 23 is provided on the bottom plate 1, which is connected to the arc space 3 and is provided with an end cap. This facilitates the replacement of the liquid in the control line 7 and can also be used in conjunction with the liquid inlet 20 to clean the inside of the control line 7.

[0043] Optionally, an arm pad 24 is provided on the control frame 5 to improve the comfort of use of the device.

[0044] Optionally, a back plate 25 is provided on the bottom plate 1, and a back pad 26 is provided on the back plate 25. This can improve the comfort of using the device.

[0045] Optionally, the footrest 2 is provided with anti-skid patterns to prevent slipping during use and make it more convenient to use.

[0046] Application scenario of an exemplary embodiment:

[0047] Before using this device, the user drives the initial adjustment plate 11 to rotate through the handle 15, and adjusts the distance of the initial adjustment plate 11 into the initial adjustment hole 14 through the thread 13, thereby controlling the internal position of the rotating plate 12 and the initial adjustment tube 10. When the control pipeline 7 is completely sealed, the liquid pressure is transmitted to the arc bar 4, driving the foot pedal 2 fixedly connected to the arc bar 4 to rise to a certain angle.

[0048] After the adjustment is completed, the user can stand on the inclined foot pedal 2 with both feet, lift the toes to stretch the tendons of the calf, and achieve the relaxation function. At the same time, the hands can press the initial adjustment plate 11 by tightening and loosening the grip adjustment part 9 to change the space in the initial adjustment tube 10, thereby changing the liquid pressure in the entire control pipeline 7. When the control pipeline 7 is completely sealed, the liquid pressure is transmitted to the arc bar 4, driving the foot pedal 2 fixedly connected to the arc bar 4 to achieve a technical effect of small ups and downs, thereby optimizing the stretching effect of the calf tendons, and making it more convenient and comfortable to use.
