The invention relates to the technical field of tire inflation, in particular to a tire inflation device. Comprising an inner pipe and a sleeve sleeving the inner pipe, and a tire gauge mounting hole and a pressure release valve mounting hole are formed in the side wall of the sleeve; the pipe wall of the inner side of the sleeve is thinned by 0.5 mm-1mm to form a broadening part, and the ends, located on the inner side of the sleeve, of the tire gauge mounting hole and the pressure release valve mounting hole are located in the broadening part. An air cavity is formed between the widening part and the outer wall of the inner pipe, a plurality of vent holes are formed in the pipe wall of the inner pipe, and the interior of the inner pipe is communicated with the air cavity through the vent holes; a plurality of fourth grooves are formed in the inner sides of the two ends of the sleeve respectively, and fourth sealing rings are arranged in the fourth grooves. The tire gauge can rotate by taking the axis of the tire gauge mounting hole as the center, the control sleeve is sleeved on the outer side of the inner pipe, the control sleeve can rotate by taking the axis of the inner pipe as the center, and a dial plate of the tire gauge can be adjusted to any direction through rotation in two directions, so that an operator can read the reading of the tire gauge at any time.
本发明涉及轮胎充气技术领域,特指一种轮胎充气装置。包括内管和套装在内管外侧的套管,套管的侧壁上开有胎压计安装孔和泄压阀安装孔;套管的内侧管壁减薄0.5mm~1mm形成为扩宽部,胎压计安装孔和泄压阀安装孔位于套管内侧的一端处于扩宽部内;扩宽部和内管的外壁之间向形成气腔,内管的管壁上开有若干个通气孔,通气孔将内管的内部和气腔之间导通;套管两端的内侧各开有若干个凹槽四,凹槽四内设置有密封圈四。胎压计可以以胎压计安装孔的轴线为中心进行转动,控制套套装在内管外侧,控制套可以以内管的轴线为中心进行转动,通过在两个方向上的转动,可以将胎压计的表盘调整至任意方向,以便于操作人员随时读取胎压计的读数。
