Abstract

The invention provides a ligament changing traction device based on track and field training, relates to the technical field of physical training equipment, and solves the problem that ligament stretching in various modes cannot be realized through structural improvement. The problems that a sliding structure is prone to collision, collision protection of the sliding structure cannot be achieved through structural improvement, and normal sliding of the sliding structure is not affected after the protection structure is collided are solved. The ligament changing traction device based on track and field training comprises a sliding seat structure; a stretching structure is installed on the sliding seat structure, and a graduated scale is further installed on the sliding seat structure. Through arrangement of a through hole and a baffle, the through hole is formed in a sliding plate, and the through hole is of a rectangular hole-shaped structure; and the through hole is slidably connected with the baffle and is not in contact with the top end face, the bottom end face, the left end face and the right end face of the baffle, and therefore the situation that sliding of the sliding plate is blocked due to slight deformation of the baffle can be prevented.

Description

technical field [0001] The invention belongs to the technical field of sports training equipment, and more specifically relates to a multi-variable ligament pulling device for track and field training. Background technique [0002] Athletics needs to stretch the leg ligaments during training, so it is necessary to use a ligament stretching device for assistance. [0003] For example, the application number: CN201921902712.7 discloses a ligament pulling device for track and field training, which relates to the technical field of training devices, specifically a ligament pulling device for track and field training, including a main rod, and both sides of the main rod are A receiving groove is provided, and a seat cushion is fixedly installed on the surface of the main rod. The ligament stretching device for track and field training is provided with foot pedals and leg placement grooves, and the foot pedals are used to assist the trainer's feet, and at the same time, the leg p...
