A training device for sitting and forward bending

Abstract

The invention provides an anteflexion training device for a seated body. A sliding plate is connected with the upper part of a box body in a sliding mode, a hand fixing device is arranged on the upper part of the sliding plate, racks are fixedly connected with the lower part of the sliding plate, the first gear and the racks drive the sliding plate to move on the upper part of the box body in a coordinated mode, a one-way transmission mechanism is connected with the second gear, the one-way transmission mechanism is connected with a spindle, ratchet wheels are fixedly mounted on a rotating shaft, a driving rod is mounted on the rotating shaft in a rotating mode, one end of the driving rod is connected with the rotating shaft in a rotating mode, a first ratchet meshing with the ratchet wheels is mounted in the middle part of the driving rod, the rotation of a press lever drives the rotation of the driving rod, the first ratchet drives the ratchet wheels to rotate, and the sliding plate is driven to move away from a user by the rotation of the ratchet wheels through the one-way transmission mechanism, the first gear, the second gear, the racks, and the one-way transmission mechanism does not pass the motion to the ratchet wheels; the user sits down to keep the exercise posture, adjusts the optimal tensile strength through the control by double feet, and the user can carry on the precise control of exercise intensity according to his own condition.

Description

technical field [0001] The invention relates to sports equipment, in particular to a sitting and forward bending training device. Background technique [0002] Sit And Reach is a physical fitness test item for primary and secondary schools. Its purpose is to measure the possible range of motion of the trunk, waist, hip and other joints in a static state, mainly reflecting the joints and ligaments in these parts. As well as the development level of muscle extensibility and elasticity and body flexibility, sitting and forward bending is one of the compulsory items in the Chinese physical education high school entrance examination. [0003] Sitting and forward bending is a test item used to reflect the flexibility of the human body. Flexibility refers to the ability of joints, muscles, tendons and ligaments to stretch when the body completes movements. The quality of flexibility depends on the anatomical structure of the joint, the volume of soft tissue around the joint and t...

Problems solved by technology

[0004] At present, the physical fitness of middle school students is getting worse and worse. On the one hand, due to the one-sided pursuit of the rate of admission, society and schools have a tendency to emphasize intelligence and despise sports. Insufficient conditions and physical education classes and sports activities for students are difficult to guarantee

In view of the phenomenon that the sitting position and forward bending are not up to standard, there is no training device to practice flexibility, and the traditional training method is accompanied by the coach to assist the leg press, but when there are too many people in the training, the coach cannot assist the leg press one by one , students have no way to apply tension to themselves to exercise flexibility. This traditional training method cannot get rid of the assistance of others. It is particularly important to provide a sitting and forward bending training device that can achieve self-training without the help of others.
