[0037] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0038] See also Figure 1-Figure 9As shown, the present invention is a physical fitness device for training sports students and a method of using the same, comprising a base plate 1, a main body bracket 2 is arranged above the base plate 1, a disc 3 is rotatably mounted on the main body bracket 2, a slide groove 4 is provided at the bottom of the disc 3, the slide groove 4 is slidably connected to a reciprocating mechanism, the reciprocating mechanism is used to control a connecting shaft 5 to be lifted and lowered, the connecting shaft 5 is slidably connected to the inside of the main body bracket 2, a cross bar 6 is arranged above the connecting shaft 5, a hole 7 is provided on the cross bar 6, a support rod 8 is movably mounted on the hole 7, a training mechanism is provided at one end of the cross bar 6, and the training mechanism is used to perform pull-ups and weightlifting training on students.

[0039] The working principle of a physical fitness device for training sports students proposed in the present invention is that when using the device, the main frame 2 is first fixed on the base plate 1, and then the disc 3 is rotated, thereby driving the slide groove 4 to rotate, and then driving the reciprocating mechanism to move, thereby driving the connecting shaft 5, the cross bar 6, the hole 7 and the support rod 8 to rise or fall, so that it can be suitable for sports students of different heights to train, and it is more convenient to use.

[0040] It is worth noting that sports students can perform pull-up and weightlifting training through training institutions, thus ensuring the diversity of training and improving training efficiency.

[0041] In one embodiment, for the above-mentioned main body bracket 2, the main body bracket 2 is fixedly installed above the base plate 1 by a first bolt 9, the disc 3 is fixedly installed with a rotating handle 10, and the reciprocating mechanism includes a connecting rod 11 arranged inside the main body bracket 2, the connecting rod 11 is slidably connected inside the main body bracket 2, one end of the connecting rod 11 is slidably connected inside the slide groove 4, and the other end is fixedly installed with a connecting member 12.

[0042] In one embodiment, for the above-mentioned connecting member 12, the connecting member 12 is slidably connected to the plate 13, the plate 13 is fixedly installed with a first rack 14 and a second rack 15, the first rack 14 meshes with the first gear 16, the second rack 15 meshes with the second gear 17, and the main frame 2 is threadedly connected with a second bolt 25, and the second bolt 25 conflicts with the plate 13.

[0043] In one embodiment, for the above-mentioned first gear 16, the first gear 16 and the second gear 17 are rotatably installed on a threaded rod 18, the threaded rod 18 is threadedly connected to the connecting shaft 5, the threaded rod 18 is fixedly connected with a first one-way bearing 19 and a second one-way bearing 20, the first gear 16 is fixedly connected to the first one-way bearing 19, and the second gear 17 is fixedly connected to the second one-way bearing 20.

[0044] The working principle of a physical fitness device for training sports students proposed by the present invention is that by rotating the handle 10, the disc 3 is driven to rotate, and then the slide groove 4 is driven to rotate. The rotation process of the slide groove 4 will cause the connecting rod 11 to drive the connecting member 12 to slide back and forth close to the center of the disc 3 and away from the center of the disc 3. The connecting member 12 drives the plate 13 to move back and forth. The movement of the plate 13 controls the movement of the first rack 14. Due to the meshing connection between the first rack 14 and the first gear 16, the first gear 16 is driven to rotate. The first gear 16 drives the threaded rod 18 to rotate through the first one-way bearing 19, thereby driving the connecting shaft 5 to rise along the inside of the main bracket 2, and then driving the connecting shaft 5, the cross bar 6, the hole 7 and the support rod 8 to rise or fall, so that it can be suitable for sports students of different heights to train, and it is more convenient to use.

[0045] It is worth noting that when the first rack 14 moves back, the first rack 14 drives the first gear 16 to rotate. Due to the presence of the first one-way bearing 19, the rotation of the first gear 16 will not drive the threaded rod 18 to rotate, so that the threaded rod 18 can only rotate in one direction.

[0046] Furthermore, by rotating the second bolt 25, the second bolt 25 moves toward the inside of the main bracket 2, thereby interfering with the plate 13, and then driving the plate 13 to slide, so that the second rack 15 is meshed and connected with the second gear 17, and finally the disc 3 is rotated. The subsequent working principle is the same as above and will not be elaborated on here, thereby lowering the connecting shaft 5, the cross bar 6, the hole 7 and the support rod 8, so that it is suitable for use by athletes of different heights.

[0047] In one embodiment, for the above-mentioned disc 3, the disc 3, the slide slot 4 and the reciprocating mechanism are arranged in two groups with the central axis of the main support 2 as the symmetry axis, and are connected through a transmission mechanism.

[0048] In one embodiment, for the above-mentioned transmission mechanism, the transmission mechanism includes a third gear 21 arranged on the main support 2, the third gear 21 is fixedly connected to the disc 3, the third gear 21 is connected to the fourth gear 23 through a gear belt 22, and the fourth gear 23 is fixedly connected to another disc 3.

[0049] The working principle of a physical fitness device for training athletes proposed in the present invention is to rotate the disc 3 to drive the third gear 21 to rotate, and then drive the fourth gear 23 to rotate through the gear belt 22, so as to realize the simultaneous movement of two sets of reciprocating mechanisms, thereby ensuring the stability of the device.

[0050] In one embodiment, for the cross bar 6 , the cross bar 6 is fixedly mounted on the connecting shaft 5 , and telescopic rods 24 are slidably mounted on both ends of the support rod 8 , and the telescopic rods 24 are snap-fitted with the holes 7 .

[0051] The working principle of the physical fitness device for training athletes proposed in the present invention is that when athletes need to adjust the spacing between multiple support rods 8 according to training conditions for physical fitness training, they can use a tool to poke the telescopic rod 24, so that the telescopic rod 24 moves to the inside of the support rod 8, and then the telescopic rod 24 is disengaged from the hole 7, so that the support rod 8 can be removed conveniently and installed inside other holes 7, thereby adjusting the spacing between multiple support rods 8, which is convenient for adjustment and use according to the training conditions of the athletes.

[0052] In one embodiment, for the above training mechanism, the training mechanism includes a movable rod 26 disposed on the main frame 2, the movable rod 26 is slidably connected to the main frame 2, a limit block 27 is fixedly installed on the top of the movable rod 26, and a shock absorbing ball 34 is fixedly installed on the movable rod 26.

[0053] In one embodiment, for the above-mentioned movable rod 26, the movable rod 26 is provided with a compression spring 28, one end of the compression spring 28 is fixedly mounted on the main frame 2, and the other end is fixedly mounted on the clamping plate 29, the clamping plate 29 is clamped with a counterweight block 30, and the counterweight block 30 is slidably connected to the handle 31, the handle 31 is fixedly mounted on the movable rod 26, the main frame 2 is fixedly mounted with a U-shaped handle 32, and the bottom plate 1 is rotatably mounted with an anti-slip disc 33.

[0054] The working principle of the physical fitness device for training sports students proposed in the present invention is that when sports students perform physical fitness training, they can pull down the handle 31 at the lower end of the movable rod 26 to perform pull-up training, or they can lift up the handle 31 to perform weightlifting training, thereby enriching the training content of sports students. At the same time, a counterweight block 30 is arranged above the sports students, and students can add or reduce the number of counterweight blocks 30 according to their own physical fitness to perform scientific training.

[0055] It is worth noting that by pulling the clamping plate 29, it is disengaged from the counterweight block 30, and then the counterweight block 30 can be added or reduced, and then the reaction force of the compression spring 28 is used to drive the clamping plate 29 to reset, so that the counterweight block 30 can be clamped.

[0056] In addition, the damping ball 34 can play a role of damping and buffering, thereby preventing a violent collision between the limit block 27 and the main frame 2 when the movable rod 26 moves up and down in the main frame 2.

[0057] The working principle of the physical fitness device for training sports students proposed by the present invention is that the user can place his feet on the surface of the anti-skid disc 33 and hold the U-shaped handle 32 with his hands to train the waist and abdomen by rotating the waist and abdomen.
