The invention provides an air tap cap capable of displaying tire pressure by pressing, which relates to the technical field of air tap caps and comprises a metal shell, a metal ejector pin movably arranged in the metal shell and used for moving downwards during pressing to jack up a valve core to open the valve core for deflation and resetting after the pressing is released, and a compression spring connected with the metal ejector pin and used for pressing the metal ejector pin to display the tire pressure. The expansion sealing ring is arranged in the metal shell, is in linkage with the valve core, expands and jacks up the green cylinder during deflation, the valve core is temporarily jacked up by adopting pressing operation to measure the tire pressure, and the valve core can be automatically reset and closed after pressing is finished. The problems that a traditional tire pressure cap ejector pin jacks a valve core for a long time and cannot be closed, and airtightness is poor are solved, it is guaranteed that gas in a tire can be stably stored, normal air pressure is maintained, and the service life of the tire is prolonged.

    本发明提供一种按压显示胎压的气嘴帽,涉及气嘴帽技术领域,包括金属外壳,金属顶针,活动设置于所述金属外壳内,用于在按压时下移以顶起所述气门芯使其开阀放气,并在释放按压后通过回弹复位,压缩弹簧,与所述金属顶针连接,用于在按压时蓄力并在释放后驱动所述金属顶针复位,膨胀密封圈,设置于所述金属外壳内,与所述气门芯联动,在放气时膨胀并顶起绿色筒,通过采用按压操作来临时顶起气门芯测量胎压,按压结束后气门芯能自动复位关闭,避免了传统胎压帽顶针长期顶起气门芯导致无法闭合、气密不良的问题,确保轮胎内气体能稳定保存,维持正常气压,延长轮胎使用寿命。
