An inflation device that ensures constant inflation content based on intermittent reciprocating motion

Abstract

The invention relates to the technical field of sports goods, and discloses an inflating device capable of ensuring constant inflating content based on intermittent reciprocating motion. The device comprises a pedestal for supporting a ball; via the matched use of a first rotation shaft, a second rotation shaft, an inflating pipe, a first limiting block, a second limiting block and a support bar,when the first rotation shaft is rotated, the inflating pipe is driven to synchronously do leftwards and rightwards intermittent reciprocating motion, to complete inflating and stop inflating, and motion time is accordant, so that an inflating volume is kept constant, and quality of a football is prevented from being damaged by insufficient inflating or excessive inflating; and via the matched useof the first rotation shaft, the second rotation shaft, the support bar and the inflating pipe, the football is relatively hard, the volume of the football before inflating and after inflating is notlargely changed, artificial judgment may have a relatively large error, a traditional artificial judgment mode is changed for inflating, the work intensities of people are relieved while the qualityof the football is ensured, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stationery and sports articles, in particular to an inflator which ensures a constant inflated content based on intermittent reciprocating motion. Background technique [0002] As an old saying goes, the body is the capital of the revolution. In order to promote overall development, improve physical quality and comprehensive education level, enhance physical fitness and improve athletic ability, improve lifestyle and improve the quality of life, people need to carry out daily physical exercises, and with the development of international exchanges The scale and level of sports development is already an important symbol to measure the development and progress of a country and society, so it cannot be ignored for sports. [0003] Sports can be divided into popular sports, professional sports, school sports and other types, including a variety of ball games, such as football, ancient football originated in Ch...

Problems solved by technology

[0003] Sports can be divided into popular sports, professional sports, school sports and other types, including a variety of ball games, such as football, ancient football originated in China, modern football originated in the United Kingdom, is considered the world's number one sport, is a global sport The most influential individual sport in the world. During the football match, the quality of the football is also very important. The football is generally made into a ball after being spliced. After the production is successful, the staff needs to inflate it at last. However, the traditional football generally has a hard shell, and the volume change after inflation is small. Therefore, the inflation content cannot be accurately judged when inflated by manual operation, and the inflation content cannot be guaranteed to remain constant. Errors are prone to occur, resulting in under-inflation or over-inflation. When the air is over-inflated, the pressure inside the ball is too high, and it is easy to cause it to burst when kicking the football with your feet. When the air is insufficient, the use effect will be affected during the kicking process.
