Description

Technical Field

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

[0002] Air resistance training equipment is a type of fitness equipment that uses air resistance to provide training load. Unlike traditional fitness equipment that uses gravity (such as free weights) or mechanical resistance (such as stacked weight plates), air resistance training equipment generates resistance by controlling airflow, thereby achieving the effect of building muscles and improving physical fitness.

[0003] Chinese Patent Publication No. CN206081489U discloses a pneumatic knee flexion and extension rehabilitation trainer, belonging to the field of rehabilitation training equipment. The technical problem to be solved is to provide a pneumatic shoulder joint push-pull rehabilitation trainer that uses a bidirectional damping cylinder as the external force loading method, which is smooth and stable and has no impact during the movement. The technical solution adopted to solve this technical problem is as follows: a pneumatic knee flexion and extension rehabilitation trainer, one end of the rotating rod is hinged to the upper end of the rotating body support frame, and the other end of the rotating rod is a free end that extends to the center line under the seat. The leg clamp is fixed to the free end of the rotating rod. The leg clamp drives the rotating rod to rotate around the hinge point between the rotating rod and the rotating body support frame through external force, thereby realizing the movement of the leg along the knee joint. The bidirectional damping cylinder is located between the rotating body and the rotating body support frame. The movable end of the bidirectional damping cylinder moves back and forth with the reciprocating rotation of the leg clamp. An air compressor provides compressed gas to the bidirectional damping cylinder.

[0004] In the field of physical training, correct posture is crucial for achieving optimal training results. Inappropriate training posture not only reduces training efficiency but can also lead to sports injuries, especially when performing exercises that require strong core strength. A stable lumbar support device that provides adequate support is particularly important in these situations. Furthermore, the correct head position also affects overall posture and training quality. Incorrect head posture can place additional strain on the cervical spine and distract the trainee from focusing on the target muscle groups. Traditional air resistance training devices are not easily adjustable to suit the user's height and lumbar condition. Utility Model Content

[0005] The purpose of this invention is to provide an air resistance physical training device that addresses the limitations of traditional air resistance training devices, which are not easily adjustable according to the user's height and waist condition. This can lead to inappropriate training postures, reduced training efficiency, and sports injuries.

[0006] This utility model provides an air resistance physical training device, including a seat cushion. A lifting rod is rotatably installed at the front end of the seat cushion. Two sets of leg clamps are symmetrically installed at the lower end of the lifting rod. The lifting rod is hinged to the piston end of a damping cylinder. The other end of the damping cylinder is hinged to the bottom of the seat cushion. A backrest is installed at the rear end of the seat cushion. A slide rail is provided on both sides of the backrest. An adjustable support component is slidably connected in the slide rail. The adjustable support component supports the user's waist.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to Figures 1 to 8This utility model provides an air resistance physical training device, including a seat cushion 1. A lifting rod 3 is rotatably mounted on the front end of the seat cushion 1. Two sets of leg clamps 4 are symmetrically mounted on the lower end of the lifting rod 3. The user places their lower legs in the gaps between the leg clamps 4 and quickly lifts the lifting rod 3 upwards for training. The lifting rod 3 is hinged to the piston end of a damping cylinder 5. The other end of the damping cylinder 5 is hinged to the bottom of the seat cushion 1. The function of the damping cylinder 5 is to provide an adjustable resistance to control the speed and force of lifting the lifting rod 3 upwards. A self-inflating damping cylinder 5 can be selected, or a damping cylinder 5 connected to an air compressor can be selected for use.

[0032] A grip bar 2 is provided on the back side of the seat cushion 1. Both ends of the grip bar 2 extend to the front side of the seat cushion 1. The grip bar 2 is provided for the user to hold and provides support.

[0033] Secondly, a backrest 6 is installed at the rear end of the seat cushion 1. Slide rails 7 are provided on both sides of the backrest 6. Adjustable support components are slidably connected in the slide rails 7 to support the user's waist.

[0034] Specifically, the adjustable support assembly includes a movable plate 8 that is slidably connected to the slide rail 7. An elastic pad 9 is provided on one side of the movable plate 8, and a slide rail 13 is provided on the rear side of the backrest 6. The movable plate 8 is slidably connected to the slide rail 13. A lead screw 14 is rotatably provided inside the slide rail 13. The lead screw 14 is threadedly connected to the movable plate 8. According to the user's height, rotating the lead screw 14 will cause the movable plate 8 to move automatically, moving the elastic pad 9 to the user's waist position.

[0035] Furthermore, screws 11 are threaded to both ends of the movable plate 8. One end of the screw 11 is rotatably connected to the adjusting arc plate 10. According to the user's waist support needs, the screw 11 is rotated to move the adjusting arc plate 10 forward to support the user's waist and make the user more comfortable during training.

[0036] Meanwhile, a spring 12 is connected between the adjusting arc plate 10 and the elastic pad 9, and the spring 12 keeps the position of the adjusting arc plate 10 stable.

[0037] Furthermore, symmetrical insertion holes 19 are provided at the upper end of the backrest 6. Insertion rods 17 are inserted into the insertion holes 19. A headrest 15 is provided at the upper end of the insertion rods 17. An airbag 16 is provided on the inner side of the headrest 15. When the user's head rests on the airbag 16, the airbag 16 can automatically adjust its shape according to the pressure of the user's head, providing a soft and even support surface for the head, which helps to reduce the pressure on the cervical spine, especially when sitting for a long time or doing physical training.

[0038] like Figure 6As shown, multiple positioning slots 18 are provided on the insertion rod 17, and a sliding sleeve 20 is provided at the upper end of the backrest 6. A positioning plate 21 is slidably arranged inside the sliding sleeve 20. The positioning plate 21 is inserted and engaged with the positioning slot 18. After the insertion rod 17 is adjusted according to the user's head height, the positioning plate 21 can be inserted into the corresponding positioning slot 18 to fix the insertion rod 17, thereby improving the stability of the headrest 15.

[0039] In summary, the working principle of the air resistance physical training device of this utility model embodiment is as follows: through the adjustable support components, the headrest 15 provides the user with a comprehensive support system. These components work together to enable the device to adapt to different users' heights, body types, and training needs, thereby ensuring that users can obtain the best comfort and safety when performing training such as leg lifting. At the same time, through the adjustable resistance provided by the damping cylinder 5, users can adjust for different training intensities to achieve better training results.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
