The second sliding shaft 7 is rotatably connected with the clamping seat 43 and the fixing seat 41, so that the barbell bar can rotate relatively in the rotation process, reducing the friction force and saving labor. Further, when the user uses the device for fixing the movement track of the barbell bar installed on the squat rack to exercise, the fitness efficiency of squat can be effectively improved. When the user squats to different heights, the body center of gravity will change to a certain extent, and at this time, the user needs to adjust the angle of grasping the barbell bar by hand to adjust his center of gravity and force exerting state.

In some embodiments, the adjusting mechanism 44 includes a U-shaped clipping seat 441; one end of the clamping seat 43 is hinged with the fixing seat 41, and the U-shaped clipping seat 441 is fixedly connected with the other end of the clamping seat 43; the fixing seat 41 is hinged with a threaded rod 442, and a rotating direction of the threaded rod 442 corresponds to a position of the U-shaped clipping seat 441, and the threaded rod 442 is provided with a threadedly connected nut 443.

In the adjusting mechanism 44, one end of the clamping seat 43 is hinged on the fixing seat 41, so that it can be opened or closed around the fixing seat 41. For fixing the barbell bar after the clamping seat 43 is closed, a U-shaped clipping seat 441 is arranged at the front end of the clamping seat 43, and a threaded rod 442 is installed at the corresponding position on the fixing seat 41, and the threaded rod 442 is hinged with the fixing seat 41. After the threaded rod 442 is rotated to the vertical state, it is just placed between the U-shaped clipping seat 441. A nut 443 is arranged on the threaded rod 442, and the nut 443 is rotated so that the nut 443 is clamped on the top of the U-shaped clipping seat 441, so that the clamping seat 43 can be fixed and closed with the fixing seat 41 to form an annular structure for fixing the barbell bar.

The setting of the adjusting mechanism 44 can not only realize the disassembly and assembly of the barbell bar, but also be adjusted according to the specifications (diameter) of the barbell bar by adjusting the position of the nut 443. In order to further ensure the stability of the barbell bar, the clamping seat 43 and the fixing seat 41 are hinged by a hinge shaft, and the clamping seat 43 is provided with a strip groove, and the hinge shaft is connected in the strip groove, and the hinge shaft is fixedly installed on the fixing seat 41.

It can also be arranged that the fixing seat 41 is provided with third pin holes for connecting the hinge shaft, and there are at least two third pin holes.

According to the diameter of the barbell bar, the connection position of the hinge shaft can be adjusted, and with the rotation of the U-shaped clipping seat 441, the clamping seat 43 can be ensured to fit the barbell bar as much as possible to ensure stability.

As shown in FIGS. 8 to 10, in some embodiments, at least two fourth pin holes 447 are provided at one end of the mounting groove 42 of the fixing seat 41 hinged with the clamping seat 43 along the height direction. The clamping seat 43 is provided with a fifth pin hole 448 corresponding to the fourth pin hole 447, and the fifth pin hole 448 is arranged as a roughly racetrack-shaped hole, and the fixing seat 41 and the clamping seat 43 are hinged through a fixing pin 83.

When clamping barbell bars with different dimensions, users can select different fourth pin holes to use barbell bars with different dimensions. Wherein, the fifth pin hole is arranged in a racetrack shape, so that when the fixing seat and the clamping seat clamp barbell bars with different dimensions, the state of the clamping seat can be adjusted to a certain extent, so that the barbell bar fully abuts against the second sliding shaft, and the rotation is smoother.

In this embodiment, the fifth pin hole is arranged in a substantially racetrack shape. In other embodiments, the fifth pin hole is not limited to the racetrack shape, but can also be set as a circle, a square, an ellipse, a semicircle, a polygon, a triangle, and any desired geometric shape.

In other embodiments, the adjusting mechanism 44 includes two pin rods 444, at least two first pin holes 445 are formed on both sides of the mounting groove 42 of the fixing seat 41, and two ends of the clamping seat 43 are provided with a second pin hole 446 corresponding to the first pin hole 445. The dimensions of the pin rods 444 are adapted to those of the first pin holes 445 and the second pin holes 446, and the movable end of the pin rod 444 is provided with a fixing bolt.

Both ends of the fixing seat 41 connected with the clamping seat 43 are provided with first pin holes 445, and there are at least two first pin holes 445 at each end, and both ends of the clamping seat 43 are provided with second pin holes 446. The first pin holes 445 and the second pin holes 446 have the same dimension. When the first pin hole 445 corresponds to the second pin hole 446, the pin rod 444 and the bolt (detachable) on the pin rod 444 are inserted to disassemble the barbell rod. For barbell rods with different specifications (diameters), it only needs to allow the second pin holes 446 at both ends to correspond to the different first pin holes 445.

Further, the device further comprises a collar 5, the dimension of which is matched with that of the barbell bar, the collar 5 is sleeved and fixedly connected to the barbell bar, and the collar 5 is connected with a hook 6.

The above-mentioned collar 5 is used to be sleeved (fixed) on the barbell bar, and the fixing sleeve can be in the form of a hoop or in other ways, so long as it can be detached from the barbell bar. The hook 6 is fixed on the collar 5, and several deep holes for hanging the hook 6 are opened in the squat rack body 2 along the height direction;

When in use, the user only needs to rotate the barbell bar outward to turn the hook 6 out of the deep hole, then reverse the barbell bar after use and hang the hook 6 in the deep hole again. Even when physical strength is exhausted during use, it only needs to rotate the barbell bar at any time and hang the hook 6 on the squat rack body 2. After fixing, the user can leave the squat rack and adjust it to an appropriate height when using it again.

As shown in FIGS. 5 to 7, in some embodiments, the device further includes an attachment rack 8, which is attached to the squat rack body 2 and arranged above the relatively sliding mounting seat 1; the attachment rack 8 is provided with a clamping part 81 which is fixedly connected with the attachment rack 8, and the clamping part 81 is provided with an attachment groove 811 for clamping the hook 6.
