Multi-mode physical training device based on physical education

Abstract

A multi-mode physical training device based on physical education comprises a base, a frame is fixedly mounted on the top side of the base, a seat plate is fixedly mounted on the frame, a backrest is fixedly mounted on the seat plate, two sliding rods are fixedly mounted in the frame, sliding sleeves are slidably mounted on the sliding rods respectively, and the two sliding sleeves are fixedly connected through a pedal, the top side of the pedal is fixedly connected with the lower end of a vertical rod, the periphery of the vertical rod is sleeved with a plurality of weight stacks in a sliding mode, a strip-shaped rack is fixedly installed on the sliding sleeve on one side, and a gear is arranged on one side of the strip-shaped rack in a meshed and matched mode. The device is simple in structure and ingenious in conception, the pedal can fall back step by step, so that the counterweight sheets are prevented from falling back rapidly for a long distance, legs of a user are protected, the counterweight blocks can stay at any position, and the situation that when the counterweight sheets are overloaded, the feet cannot be pulled down from the pedal in time is avoided; meanwhile, the pedal can continuously fall back, so that the leg strength training is kept continuous, the market requirement can be met, and the device is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of physical training devices, in particular to a multi-mode physical training device based on physical education teaching. Background technique [0002] The reverse pedal is a commonly used equipment for physical training, but when the reverse pedal retracts the legs to move the weight block downward, because the strength of the legs is in a decreasing process at this time, it is easy to cause the force to be too strong, and the weight plate falls quickly, thus There is a lot of pressure on the legs, and the legs are often folded. There are risks in the use of the reverse pedal, which cannot meet the actual needs. Therefore, we have invented a multi-mode physical training device based on physical education teaching. Contents of the invention [0003] The invention provides a multi-mode physical fitness training device based on physical education teaching to solve the defects in the prior art. [0004] The present i...
