Physical training device for physical education classroom teaching

Abstract

The invention provides a physical training device for physical education classroom teaching. The device comprises a supporting frame, and the supporting frame comprises a vertical supporting frame making contact with the ground. The upper end of the vertical supporting frame is detachably and fixedly connected with a transverse supporting frame; the transverse supporting frame is detachably and fixedly connected with two guide rollers of a parallel structure, a connecting frame of a U-shaped structure is connected to the position, located on one sides of the two guide rollers, of the transverse supporting frame, the connecting frame of the U-shaped structure comprises two parallel rods which are parallel and equal in length, one end of each connecting frame is fixedly connected with a supporting rod, and the outer wall of each supporting rod is rotationally connected with a fixed pulley; rigid ropes are wound on the surfaces of the guide roller and the fixed pulley; a hand ring is hinged to one end of the rigid rope, and a weight box is hinged to the other end; a tapping rope is hinged to the outer wall of the steel rope, and a clamping ring is hinged to the free end of the tappingrope; a clamping head is fixed to the transverse rod, the clamping ring is matched with the clamping head, and therefore the clamping ring can be connected to the clamping head in a sleeving mode. Physical training can be carried out on students, and the use safety can be improved.

Description

technical field [0001] The invention relates to the technical field of physical training equipment, in particular to a physical training device for physical education classroom teaching. Background technique [0002] Physical fitness is the basic athletic ability of the human body manifested through sports qualities such as strength, speed, endurance, coordination, flexibility, and agility. It is an important component of an athlete's competitive ability. They are closely related, and in physical education classroom teaching, in order to improve the physical fitness of each student, special physical training is required. [0003] However, the existing physical training devices usually cannot safely separate the counterweight object from the trainer during physical training. When the trainer overtrains and causes fatigue, the counterweight object will easily fall on the trainer's feet. , thus causing accidental injuries to trainers and reducing the safety of the physical tra...
