Description

Technical Field

[0001] The present invention relates to the technical field of physical training equipment, and in particular to a pull-up training device for high-intensity physical training. Background Art

[0002] Pull-ups are a suspension strength exercise that uses one's own strength to overcome one's own weight. They require a certain level of grip, upper body, and shoulder girdle strength, which must be sufficient to overcome one's own bodyweight to complete. Pull-ups play an important role in developing upper body suspension strength, shoulder girdle strength, and grip strength, and are therefore often performed during high-intensity physical training.

[0003] At present, the common pull-up training devices in the prior art lack safety protection devices. When the trainee's physical strength suddenly cannot support it, it is easy to fall down, which is quite dangerous, making the safety during training not guaranteed. Moreover, when performing high-intensity physical training, weight training is generally performed by tying sandbags, which is not convenient for quickly adjusting the weight level. Moreover, the pull-up training devices in the prior art are relatively simple and lose their function when not performing pull-up training. Moreover, it is difficult to raise or lower the pull-up training device according to the actual situation during use, and the use is not convenient.

[0004] In response to the above problems, the present invention document proposes a pull-up training device for high-intensity physical training. Summary of the Invention

A first return spring 2028 is fixedly connected between the positioning block 2027 and the side wall of the storage chute 2026.

[0050] In this embodiment: by tying the leg strap 3031 to the ankle of the person and the waist strap to the waist of the person, after the person's hands slip off, the connecting rope 2043 can be pulled down by gravity, and the first transmission gear 2032 and the second transmission gear 2025 are driven, so that the first rotating shaft 2024 drives the rotating disk 2029 to move rapidly, so that the centrifugal force throws the blocking block 2027 out and locks it with the limiting ratchet 2022, which can lock the person's falling position, and because the leg strap 3031 is connected to the person's lower body, the training weight device 301 can fall to keep the person's lower limbs below, thereby avoiding the problem of the person's head hitting the ground and causing increased injuries, which can greatly improve the safety of personnel training, and during weightlifting training, the waist belt can also be tied to the physical training horizontal bar 1021, so that when the person is weak, the position of the training weight device 301 can be locked, thereby reducing the damage to the person.

[0051] Working principle: During training, the personnel will tie the waist belt around their waist, and then perform pull-up training on the physical training horizontal bar 1021. When the human body slips during training, the acceleration of human gravity drives the waist belt and the connecting rope 2043 to move downward, and the connecting rope 2043 drives the rope disc 2042 to rotate, so that the second shaft 2031 drives the first transmission gear 2032 to rotate, and the first transmission gear 2032 and the second transmission gear 2025 drive the second transmission gear 2025 to drive the first shaft 2024 to rotate, and the first shaft 2024 drives the rotation The disc 2029 rotates rapidly, causing the rotating disc 2029 to throw the blocking block 2027 out of the storage chute 2026 through centrifugal force. The blocking block 2027 is locked with the limiting ratchet 2022, so that the angle of the rotating disc 2029 is locked. In this way, the angle of the second rotating shaft 2031 and the rope drum 2042 is locked, and the length of the connecting rope 2043 is locked to maintain the position of the waist belt, which can play a protective role for the person. When the person is tied to the ankle by the leg strap 3031, the person's lower limbs are caused to fall due to gravity through the training weight device 301, effectively preventing the risk of the person's head hitting the ground.

[0052] Secondly, remove the adjustment sleeve 1022 through the fixing bolt 1026, and take out the fixing rod 1025 from the adjustment port 1014 through the adjusting sleeve 1022, then insert the fixing rod 1025 into the limit socket 306, and then fix the position of the adjustment sleeve 1022 through the fixing bolt 1026. At this time, the person can push up the training weight device 301 through the physical training horizontal bar 1021, so as to perform weightlifting strength training.

[0053] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
