[0063] Example 1

[0064] like Figure 1-5 As shown, the gyroscope for stretching exercises includes two symmetrically arranged gyroscope handle structures, each gyroscope handle structure is fixedly connected to a support arm 1, and an angle adjustment mechanism is arranged between the two support arms, and the angle adjustment mechanism is used to support the two support arms and adjust the plane angle and vertical inclination angle of the two support arms.

[0065] The swing handle structure comprises a swing handle seat 2 arranged at the outer end of the support arm, and a swing handle 3 is rotatably connected to the swing handle seat.

[0066] The angle adjustment mechanism includes a support seat 4, on which a worm gear structure is arranged, and the outer end of a worm 5 of the worm gear structure is fixedly connected to a rotating handle 6; vertical rotating shafts 7 are arranged on the support seats on both sides of the worm gear structure, and the support arms 1 are sleeved on the vertical rotating shafts; the two support arms are used to adjust the vertical tilt angle as a whole through the worm gear structure, and the two support arms are used to adjust the angle on a certain inclined plane through the vertical rotating shafts 7.

[0067] The worm gear structure includes a horizontal shaft 8 arranged on the support seat 4, a worm wheel 9 is sleeved on the horizontal shaft, a worm 5 is meshed below the worm wheel, and the end of the worm is rotatably fixed on the support seat; bearing seats 10 are fixed at both ends of the horizontal shaft, and the vertical rotating shaft 7 is arranged in the bearing seats 10.

[0068] The support seat 4 includes a rear support plate 11, a shaft seat 12 is fixedly connected to the front side of the rear support plate, the horizontal axis 8 is arranged on the shaft seat, the worm gear 9 is fixedly sleeved on the horizontal axis 8 in the shaft seat, and the bearing seat 10 is relatively fixed at both ends of the horizontal axis outside the shaft seat, the bearing seat is rotatably connected to the shaft seat via the horizontal axis, the bearing seat drives the support arm 1 thereon to adjust the vertical tilt angle via the horizontal axis, and the support arm 1 is rotatably connected to the bearing seat 10 via the vertical rotating shaft 7 on the bearing seat 14.

[0069] A hoop plate 13 is fixedly connected to one side of the rear support plate, and a slide groove is arranged on the inner side of the hoop plate.

[0070] Two rollers 16 are also arranged on the top of the rear side of the rear support plate, so as to facilitate the sliding contact of the gyroscope when it slides up and down after being connected to the frame body to which it is slidably connected through the hoop plate.

[0071] When in use, the stretching exercise cyclotron is connected to a training frame, such as a tower, through a support seat 4. The tower is a Zen soft tower. Specifically, the hoop plate 13 behind the rear support plate 11 of the support seat is held and slid up and down with one side of the front side of the tower, and the weight adjustment structure on the tower and the top of the stretching exercise cyclotron are connected by a pull rope. In this way, the cyclotron can move down along the front side of the tower by a certain amplitude under the action of the pull rope and the weight adjustment mechanism, so that the trainee can perform upper limb gravity stretching training and complete the stretching exercise of the upper limbs, wrists, and joints. In the original state, the support arm is on a horizontal plane, and the trainee holds the swing handles 3 on the swing handle seat 2 with both hands, and can simultaneously perform horizontal rotation exercises of the two swing handles in the same or opposite directions to exercise the wrists and joints. The swing handles 3 can also be held and pulled downward. At this time, the cyclotron pulls the weight adjustment structure on the tower through the pull rope to achieve the trainee's stretching weight training. According to the training needs, the angle adjustment mechanism can be adjusted to make the two support arms rotate upward or downward at a certain angle at the same time. At this time, the rotary handle 3 will tilt as the support arm 1 rotates up and down, and the trainee is equivalent to doing stretching exercises on a certain inclined plane. The adjustment process of the angle adjustment mechanism is specifically as follows: the rotating handle 6 is rotated in a certain direction, the worm 5 engages with the worm wheel 9, drives the worm wheel 9 to rotate, the horizontal axis 8 where the worm wheel is located rotates, and drives the bearing seat 10 connected thereto to rotate synchronously, and the vertical rotating shaft 7 on the bearing seat drives the support arm to tilt synchronously, thereby completing the vertical tilt adjustment of the support arm at a certain angle. At this tilt angle, the trainee continues to hold the rotary handle 3 and rotate it to practice. By adjusting the above operation in the opposite direction through the angle adjustment mechanism, the support arm can be adjusted to another tilt angle in the opposite direction to meet the training needs.

[0072] Example 2

[0073] like Figure 6 As shown, the cyclotron for stretching exercises is the same as the cyclotron for stretching exercises in Example 1, except that a pulley seat 14 is fixedly connected to the bottom end of the support seat, and a fixed pulley 15 is arranged at the bottom end of the pulley seat; a roller similar to the rear side of the rear support plate can also be arranged on the upper rear side of the pulley seat to facilitate the flexibility of the entire cyclotron when sliding up and down on the tower.

[0074] The rear side of the pulley seat is flush with the rear side of the rear support plate 11. When in use, the pulley seat 14 drives the fixed pulley 15 to slide up and down along the front side of the tower along with the gyroscope.

[0075] By adding the pulley seat 14, the pull rope on the tower can be made to go around the fixed pulley 15 from the bottom end upwards, thereby completing the stretching training at this position.

[0081] A third pull rope 34 is also arranged between the second weight adjustment structure 22 and the fourth fixed pulley 28, and a sixth fixed pulley 35 is also arranged at the bottom end between the counterweight mechanism and the rear side of the tower. One end of the third pull rope is fixedly connected to the second weight adjustment mechanism, and the other end is arranged to pass through the lower fixed pulley group 31, the sixth fixed pulley 35, the third fixed pulley 27 and the fourth fixed pulley 28 in sequence. The outer end of the third pull rope passes through the fourth fixed pulley 28 and is connected to the pull ring.

[0082] The second and third tension ropes on the tower frame each include two groups, and the third tension rope is shown in the figure as only one group, which does not affect the understanding of the working process of the stretching frame by those skilled in the art.

[0083] The first weight adjustment structure 18 comprises a first slide plate 18.1 which is slidably matched with the first slide rail 19, and a first shaft rod 18.2 is fixed in the middle of the first slide plate; slide plate wheels 18.3 are relatively arranged on the inner side of the first slide plate 18.1 close to the first slide rail 19, and the slide plate wheels are slidably matched with both sides of the first slide rail; a pull rope fixing hole 18.4 is arranged at the top of the first slide plate.

[0088] The guide wheel 23 is connected to the top of the tower for horizontal rotation via a fixing member.

[0089] When in use, the tower frame 39 provided with the stretching exercise gyroscope can be used to perform more diverse stretching training programs. The trainee can hold the gyroscope handle 3 of the stretching exercise gyroscope, rotate the handle, and perform wrist and joint exercises while pressing the stretching exercise gyroscope downward. At this time, the stretching exercise gyroscope will pull the first pull rope 32 on the tower frame after being pulled downward, and then the first pull rope will pull the first weight adjustment structure 18 upward to complete the wrist and joint training exercises of a certain weight.

The specific operation of the adjustment is referred to the use process of the cyclotron in Example 1, which will not be described in detail here.

[0091] The trainee can also pull the second pull rope 33 with the upper or lower limbs. When the second pull rope passes through the upper fixed pulley group 30 and the guide wheel 23 and receives the tension of the pull ring at its free end, it will drive the second weight adjustment structure 22 to slide along the second slide rail 21. The second skateboard 22.1 slides along the second slide rail 21 through the skateboard wheel 22.3, thereby adding gravity to the stretching exercise of this training method and realizing gravity-regulated stretching training.

[0092] The trainee can also pull the third pull rope 34 with the upper limbs or lower limbs, and the free end of the third pull rope finally winds around the fourth fixed pulley 28. Compared with the second pull rope, the training at this position changes the pulling force position and direction of the pull rope. The third pull rope slides through the second weight adjustment structure 22, so that the trainee can achieve gravity adjustment stretching training at this position of the tower.

[0094] like Figure 9-10 As shown, the stretching training device includes the stretching fitness frame described in Example 3 and a training bench 38 used in conjunction with the stretching fitness frame.

[0095] The training bench 38 is used in a separate form with the stretching and fitness frame.

[0096] The training bench of the stretching training device can adopt other existing Zen soft bench structures used for Zen soft training, or can adopt a height-adjustable bench body to meet the height requirements of different trainees.

[0097] superior Figure 9-10 The pull rope is not shown in the figure, which does not affect the understanding of the structure and use of the training device by those skilled in the art.

[0098] During use, the training bench 38 is placed in the middle of the front side of the tower 39, with a proper distance from the tower, and the trainee lies or sits on the training bench to complete the stretching training of the upper and lower limbs. The specific stretching training items refer to the use process of the stretching fitness rack in Example 3, which will not be described in detail here.
