Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a physical training device with adjustable training intensity. Background Art

[0002] Traction devices are often used in physical training. They mainly use their own strength to resist and improve the mobility of the limb affected by periarthritis of the shoulder. For physical trainers, traction devices can exercise the muscles of the shoulders, wrists, and arms, improve the flexibility of the upper limbs, enhance the flexibility of the muscles and ligaments around the shoulder joint, and have a positive rehabilitation effect on functional disorders and chronic injuries of the shoulder joint.

[0003] A search revealed a Chinese patent application with publication number CN219896943U, which discloses a physical training tractor for physical education. The tractor comprises a column, a connecting rod, and a traction chain. Connecting rods are provided on both sides of the column's top, with rocker arms movably connected to the outer sides of the connecting rods. The rocker arms are connected to the traction chain on both sides, and the bottom of the traction chain is connected to a grip ring. An adjustment mechanism is provided within the column, comprising a movable groove, a docking block, a connecting rod, a mounting plate, a mounting hole, a fastening pin, and a motor. The movable grooves are provided on both sides of the column's surface. The tractor can be moved to a desired height by a motor-driven rocker arm, making it suitable for use by people of different heights. A protective sleeve provided on the outer side of the grip ring prevents direct contact between the user's hand and the grip ring, making the tractor more comfortable to use.

[0004] The working principle of the above patent mentions that "first bend the protective sleeve 8 from the opening to both sides. Since the rubber protective sleeve 8 itself has a certain elasticity, the protective sleeve 8 can be easily bend to both sides, and then the protective sleeve 8 is placed on the outside of the grip ring 5, and the two sides of the protective sleeve 8 are pressed inward until the limit groove 9 on the inner wall of the protective sleeve 8 is engaged with the limit block 7. By setting the protective sleeve 8 on the outside of the grip ring 5, the user's hand can be prevented from directly contacting the surface of the grip ring 5, thereby making the physical training traction device more comfortable when used." However, in the above document, since the angle of the rocker arm is fixed, when the rocker arm angle is not suitable for the user's body structure or sports skills, it will lead to incorrect sports posture and force transfer, increasing the risk of sports injuries. In response to the above problems, a physical training device with adjustable training intensity is proposed to solve the above problems. Utility Model Content

[0040] Working principle: When it is necessary to adjust the angle of the rocker arm 12, the motor 5 protected in the movable sleeve 4 can be started to drive the active bevel gear 7 on the connecting shaft 6 to rotate, so that the active bevel gear 7 engages the driven bevel gear 1 9 and the driven bevel gear 2 11 on both sides to rotate. Because the driven bevel gear 1 9 is limited to rotate in the middle position of the U-shaped block 1 8, and the driven bevel gear 2 11 is limited to rotate in the middle position of the U-shaped block 2 10, and the U-shaped block 1 8 slides on the outside of the driven bevel gear 2 11, when the active bevel gear 7 rotates, the driven bevel gear 1 9 and the driven bevel gear 2 11 will respectively drive the U-shaped block 1 8 and the driven bevel gear 2 11 to rotate with the connecting shaft 6 as the center to adjust the angle between the two rocker arms 12, so that the distance between the rocker arms 12 is more suitable for the user's body structure or sports skills, thereby maintaining the correct sports posture and force transmission, and reducing the risk of sports injuries.

[0041] When the device needs to be moved, the handle and the wheel 28 can be used to push the device to the appropriate position, and then the pedal 24 can be stepped on to drive the rotating rod 23 with the connecting shaft 22 as the center. When the rotating rod 23 rotates, because the rotating rod 23 and the rotating rod 3 21 are fixedly connected, when the rotating rod 23 rotates, the rotating rod 3 21 will also rotate synchronously. Then, through the connection of the connecting rod 20, the rotating plate 19 is driven to rotate with the positioning block 18 as the center, so that the rotating plate 19 and the rotating rod 3 21 at the position of the connecting rod 20 rotate in the opposite direction, and the support sleeve 17 is lifted to allow the sleeve 17 to slide inside the protective block 27, so that the protective block 27 extends the length of the sleeve 17, so that the position of the protective block 27 is lower than the height of the wheel 28, thereby fixing the bottom of the base 1.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
