The invention relates to the technical field of inflating valve structures, and discloses an inflating valve structure for an automobile tire, the inflating valve structure comprises an inflating valve body, a group of limiting ring I and a group of limiting ring II are respectively arranged between the top of the inner cavity of the inflating valve body and the bottom of the inner cavity of the inflating valve body; an upper valve element is movably connected to the position, located below the limiting ring I, of the top of the inner cavity of the inflating valve body in a sleeved mode, and a communicating groove I is formed in the top of the inflating valve body. According to the inflating valve structure for the automobile tire, due to the arrangement of the communicating groove II, the two cavities, separated by a lower valve element, in the inflating valve body can be achieved, meanwhile, the direction of the acting force of high-pressure gas in the automobile tire on the lower valve element is changed, and the direction of the acting force is perpendicular to the stress direction of the lower valve element when the lower valve element moves up and down, therefore, the sealing effect on the communicating groove II is effectively improved, the escape phenomenon of high-pressure gas filling in the automobile tire is avoided, and the stability and the reliability are relatively high.

    本发明涉及气门嘴结构技术领域,且公开了一种用于汽车轮胎的气门嘴结构,包括气门嘴阀体,所述气门嘴阀体内腔的顶部和内腔的底部之间分别设有一组限位环Ⅰ和限位环Ⅱ,所述气门嘴阀体内腔的顶部且位于限位环Ⅰ的下方活动套接有上阀芯,所述气门嘴阀体的顶部开设有连通槽Ⅰ。该用于汽车轮胎的气门嘴结构,对于连通槽Ⅱ的设置,既可以实现对气门嘴阀体中被下阀芯所分隔的两个腔室,同时,又改变该汽车轮胎内的高压气体对于下阀芯作用力的方向,使其与下阀芯上下活动时的受力方向相垂直,进而有效地提高了其对于连通槽Ⅱ的密封效果,避免了该汽车轮胎内所填充的高压气体发生“逃逸”的现象,稳定性及可靠性较高。
