The invention relates to the technical field of inflation devices, and discloses an inflation connecting piece which comprises a valve seat, a push rod, a spring and a pipe connecting air nozzle, the valve seat is connected with the pipe connecting air nozzle, a first air channel and a second air channel which are connected are arranged in the valve seat, the drift diameter of the first air channel is smaller than that of the second air channel, and a baffle plate larger than the drift diameter of the first air channel is arranged at one end of the push rod. The spring is arranged in the second air channel and abuts against the baffle plate and the pipe connecting air nozzle, and the push rod can abut against the valve seat to block the first air channel under the pressure of the spring and can also move towards the pipe connecting air nozzle due to the pressure of the tire air nozzle to communicate the first air channel with the second air channel. Compared with the prior art, stable connection and disconnection of the first air channel and the second air channel are achieved by arranging the push rod with the shielding plate, then the assembly condition of the inflation connecting piece and the tire valve is clearly judged, arrangement of additional parts and a large amount of redundant operation are omitted, and the assembly efficiency is effectively improved.

    本发明涉及充气装置技术领域,公开了一种充气连接件,包括阀座、推杆、弹簧和接管气嘴,阀座与接管气嘴相连接,阀座内设有相连接的第一气道和第二气道,第一气道的通径小于第二气道的通径,推杆的一端设有大于第一气道通径的遮挡板,弹簧设于第二气道内并分别抵靠遮挡板和接管气嘴,推杆可在弹簧的压力下抵靠阀座封堵第一气道,也可因轮胎气嘴的压力向接管气嘴移动连通第一气道与第二气道相连通。与现有技术相比,本申请通过设置具有遮挡板的推杆实现了第一气道与第二气道的稳定通断,进而明确判断充气连接件与轮胎气嘴的装配情况,省去了额外部件的设置与大量的多余操作,有效提升了装配效率。
