Javelin training device

Abstract

The invention discloses a javelin training device. The javelin training device comprises a left standing column and a right standing column. A position-adjustable pulley rack is mounted in the left standing column, a pulley is mounted on the pulley rack, and a balancing weight located below the pulley is arranged in the left standing column. The right standing column comprises an inner slide rod. A height-adjustable outer slide sleeve in slide fit with the inner slide rod is arranged on the inner slide rod. A soft steel wire is hinged to the outer slide sleeve, and the other end of the soft steel wire is pulled to the left standing column, wound the pulley and fixedly connected to the balancing weight. A javelin simulating sleeve corresponding to the weight of a javelin slidably sleeves the soft steel wire. Parallel buffer blocks slidably sleeve the side, close to the right standing column, of the soft steel wire. A spring is fixedly connected between every two adjacent buffer blocks. The javelin training device has the advantages that the device is small in floor space, low in site requirement, capable of being demounted and moved after use, capable of achieving automatic returning, high in safety coefficient, and capable of effectively aiding training to allow the training to be standard; only when the set angle is satisfied, the javelin simulating sleeve can be thrown far, and the javelin simulating sleeve can return fast after hitting the buffer blocks; when angle deviation exists, the javelin simulating sleeve meeting resistance vibrates up and down along the steel wire, a poor longitudinal-axis exerting effect exists, and the javelin simulating sleeve returns slowly even stops.

Description

Technical field: [0001] The invention relates to a sports training device, in particular to a javelin training device. Background technique: [0002] At present, domestic throwing coaches mainly use special throwing means: throwing rubber balls of different weights, rubber balls, small iron balls, heavy javelins, solid balls and other equipment to improve the athletes' special throwing ability of javelins. It has played a positive role in improving the throwing ability of athletes. With the continuous advancement of science and technology, the research and development of specialized training equipment is still in its infancy, and many specialized training equipment still rely on imports and introductions. Based on this, the javelin whip training device in this study aims to enrich the means of throwing training. [0003] The traditional javelin training field requires a large field, and the thrown javelins must be picked up during the training process, which wastes time and...

AI Technical Summary

Problems solved by technology

[0003] The traditional javelin training venue requires a larger venue, and the thrown javelin must be picked up during the training process, which wastes time and reduces the number of javelin training

In addition, the traditional javelin is not safe during training, and it is prone to accidents and injuries
