Abstract

本实用新型涉及一种能够自动充气的自行车内胎。它是由内胎、气囊、单向进气阀和单向排气阀构成,气囊置于车轮内胎的内部,其上连有单向进气阀和单向排气阀;单向进气阀的进气端口连通大气,进气端周围与车轮内胎密封;单向排气阀的出口连通车轮内胎空腔。当车轮内胎的气压不足时,车体的重量将会使车轮内胎及其胎内的气囊变形,这时气囊内的气体由单向排气阀排入车轮内胎空腔。

Description

自动充气的自行车内胎
所属技术领域
本实用新型涉及一种充气内胎,尤其是一种能够自动充气的自行车内胎。
背景技术
众所周知,我国是一个上亿辆自行车的王国。从整体上讲,这上亿辆自行车的应用给我们的工作、生活带来许多方便,但是,由于自行车需要充气的原因,所以也给人们带来一些不便。针对这一现实问题,本实用新型推出一种自动充气的自行车内胎。
发明内容
一种自动充气的自行车内胎,它是由内胎、气囊、单向进气阀和单向撑气阀构成,气囊置于车轮内胎的内部,其上连有单向进气阀和单向排气阀;单向进气阀的进气端口连通大气,进气端周围与车轮内胎密封;单向排气阀的出口连通车轮内胎空腔。
当车轮内胎的气压不足时,车体的重量将会使车轮内胎内的气囊变形,这时气囊内的气体由单向排气阀排入车轮内胎空腔。当车轮转动后,被压缩的气囊可凭借自身的弹性和大气的压力通过单向进气阀对气囊充气。周而复始,车轮内胎便可以被充足气体。
附图说明
下面结合附图和实施例对本实用新型做进一步说明。
附图1为本实用新型的示意图。
其中,1、车轮内胎,2、气囊,3、单向排气阀,4、单向进气阀。
具体实施方式
当车轮内胎(1)气压不足时,车体的重量将会使车轮内胎(1)内的气囊(2)产生挤压变形,这时气囊(2)内的气体便可以由单向排气阀(3)排入车轮内胎(1)空腔内。当车轮转动后,气囊(2)可凭借自身的弹性和大气的压力通过单向进气阀(4)对气囊(2)再充气。周而复始,车轮内胎(1)便可以被充足气体。

Claims (1)

1、一种由内胎、气囊、单向进气阀和单向排气阀构成的自动充气的自行车内胎,其特征在于:气囊置于车轮内胎的内部,其上连有单向进气阀和单向排气阀;单向进气阀的进气端口连通大气,进气端周围与车轮内胎密封;单向排气阀的出口连通车轮内胎空腔。
