Four-limb training device for physical education

Abstract

The invention discloses a four-limb training device for physical education, which comprises a bottom plate and a seat, and further comprises a pedal box which is fixedly arranged on the bottom plate and is positioned on the front side of the seat, the pedal box is provided with a rotatable pedal, and the pedal is in transmission connection with a flywheel arranged in the pedal box through a transmission assembly; the two traction assemblies of the same structure are installed on the bottom plate and arranged on the left side and the right side of the seat respectively, each traction assembly comprises a stand column, a steel cable, a counterweight part and a pull ring, the bottom end of each stand column is fixedly connected with the bottom plate, a first pulley is installed at the top end of each stand column, a cantilever rod is arranged on each stand column, the cantilever end of the cantilever rod faces the side, close to the seat, of the stand column and is provided with a second pulley. The counterweight parts are located on the side, away from the seat, of the stand columns, one end of the steel cable is connected with the counterweight parts, and the other end of the steel cable sequentially bypasses the first pulleys and the second pulleys and then is connected with the pull rings; the four-limb synchronous training can be carried out, and the coordination of four-limb movement is improved.

Description

technical field [0001] The invention relates to the field of limb training devices, in particular to a limb training device for physical education. Background technique [0002] Physical education is a purposeful and organized teaching process in accordance with certain plans and curriculum standards. Its task is to impart physical education knowledge, technology and skills to students, enhance students' physical fitness, and cultivate students' morality, will, and quality. The basic form of sports realization is one of the ways to implement sports goals. Now, limb training devices are often used in physical education teaching, and limb training devices are used to assist students in teaching. [0003] There are many types of limb training devices on the market today, which can basically meet the needs of teaching, but there are still some shortcomings. The specific problems are as follows: [0004] (1) The existing limb training device has a single training mode, cannot st...

AI Technical Summary

Problems solved by technology

[0004] (1) The existing training mode of this type of training device for limbs is single, and the synchronous training of the limbs cannot be carried out stably, it is difficult to improve the coordination of the movement of the limbs, and the practicability of the training device is low;

[0005] (2) The counterweights of existing limb training devices of this type are generally fixed by bolts, and the bolts need to be pulled out to adjust the training intensity, but the fixed way of the inserted bolts is unstable, and there are potential safety hazards;

[0006] (3) During the use of the existing limb training device, there is no buffer device, the potential energy of the counterweight falling cannot be relieved when the counterweight moves up and down, and the training device is prone to damage
