The invention provides an American valve air tap cap capable of displaying pressure through pressing, and relates to the technical field of air tap caps, the American valve air tap cap comprises a shell, a pressure gauge shell, a spring tube, a pressure gauge cover, a pressure gauge cover, a pressure gauge cover and a pressure gauge cover, the bottom of the shell is provided with a bottom shell, the bottom shell is provided with a thread structure matched with an American valve, and the spring tube is fixed in the shell and is provided with scales printed on the surface. The spring tube is a hollow spiral copper tube, the spring tube stretches after being inflated and drives the pointer to rotate around the circle center, the pressure value is displayed through the scales, the pressure gauge shell with the scales printed on the surface is fixedly arranged in the shell, and the spring tube made of the hollow spiral copper tube is connected with the pressure gauge shell through brazing. When the pressure gauge is used, gas in the tire enters the spring tube, the inflated spring tube stretches, the stretching action can drive the pointer connected with the spring tube to rotate around the circle center, and a user can directly and clearly read the pressure value of the current tire through the scales on the pressure gauge shell.

    本发明提供一种按压显示压力的美嘴气嘴帽,涉及气嘴帽技术领域,包括外壳,所述外壳的底部设有底壳,所述底壳设有与美式气嘴适配的螺纹结构,压力表壳,固定于外壳内部,表面印有刻度,弹簧管,通过钎焊与压力表壳连接,所述弹簧管为空心螺旋铜管,充气后舒展并带动指针绕圆心旋转,通过刻度显示压力值,通过在外壳内部固定设有表面印有刻度的压力表壳,并将空心螺旋铜管制成的弹簧管通过钎焊与压力表壳连接,当空心通气顶针顶起气门芯,轮胎内气体进入弹簧管,充气后的弹簧管会舒展,这种舒展动作会带动与弹簧管相连的指针绕圆心旋转,用户可以直接通过压力表壳上的刻度清晰读取当前轮胎的压力值。
