Problems solved by technology

[0003] During the hammer throwing process, the athlete and the hammer rotate at the same time, and the rotation center of the athlete and the hammer is located on one foot of the athlete. In the case of fast rotation, the athlete must maintain the centripetal force of the athlete's rotation around the foot and the centripetal force of the hammer rotation around the foot. Force balance, when beginners practice the hammer throw that can improve their own speed, strength and explosive power, because the hammer throw is far away from the beginners, the centripetal force they receive is relatively large, and it is not easy to maintain the balance of the two forces when the rotation is fast. Sometimes beginners will fall and be injured when they turn fast, so a physical training device for physical education that can adjust the centripetal force of the hammer is proposed.

Abstract

The invention discloses a physical training device for physical education, which belongs to the technical field of physical training. The physical training device for physical education is provided with a handle and a chain connected to the handle at one end, and also includes: an adjustment device, the adjustment device includes a second sphere and a plurality of first spheres arranged evenly at intervals, and the first sphere passes through the chain The other end of the second sphere is fixedly connected with the chain; the second sphere is provided with a through hole, the chain is passed through the through hole, and the wall of the through hole is provided with a first cavity symmetrical to the axis of the through hole. The side wall of a cavity is rotatably connected with two ends of two rotating shafts. The two rotating shafts are perpendicular to the axis and located on both sides of the axis. A plurality of plates are fixedly distributed on the arc surface of the rotating shaft; When turning to the limit speed and it is difficult to maintain the balance of the two forces, control the second sphere to move towards the handle to reduce the centripetal force generated by the second sphere on the human body, and beginners can adjust the state in time to prevent falling.

Description

technical field [0001] The invention relates to the technical field of physical training, in particular to a physical training device for physical education. Background technique [0002] The hammer throw is a long-distance throwing event in track and field sports. The athlete holds the handle of the iron chain on the hammer with both hands, and the person drives the hammer to rotate, and finally exerts force to make the ball go out of the hand. [0003] During the hammer throwing process, the athlete and the hammer rotate at the same time, and the rotation center of the athlete and the hammer is located on one foot of the athlete. In the case of fast rotation, the athlete must maintain the centripetal force of the athlete's rotation around the foot and the centripetal force of the hammer rotation around the foot. Force balance, when beginners practice the hammer throw that can improve their own speed, strength and explosive power, because the hammer throw is far away from ...
