The invention provides a life-saving water key and a life jacket. An inner cavity of a shell of the lifesaving water key is divided into a pressing contact cavity and an installation cavity, and an inflation device is installed in the installation cavity and communicated with a lifesaving air bag through an exhaust switch. The inner cavity wall of the pressing contact cavity is provided with a hole opening area and an exhaust hole, the expanding diaphragm is arranged on the hole opening area in a sealing and covering mode, and the outer side of the expanding diaphragm is communicated with the outside through a water inlet hole of the hole opening area. The elastic supporting assembly is arranged in the pressing contact cavity and abuts against the inner side of the expanding diaphragm. The inner side of the expanding diaphragm is communicated with the outside through the exhaust hole; the transmission part is arranged on the shell, and the elastic supporting assembly is connected to the exhaust switch through the transmission part. According to the water key for lifesaving, the elastic supporting assembly abuts against the inner side of the expanding diaphragm, the elastic supporting assembly supports the expanding diaphragm through the elasticity of the elastic supporting assembly, the balancing weight presses the elastic wire so that the expanding diaphragm can be tightly attached to the hole opening area and tends to be in a stable state, and therefore the situation of false triggering can be better reduced.
本公开提供一种救生用水钥匙及救生衣。上述的救生用水钥匙的壳体的内腔分隔为压触腔及安装腔,充气装置安装在安装腔内,充气装置通过排气开关连通于救生气囊;压触腔的内腔壁上设有开孔区域及排气孔,撑胀隔膜密封盖设于开孔区域,撑胀隔膜的外侧通过开孔区域的进水孔与外界连通;弹性支承组件设置于压触腔内,并抵持于撑胀隔膜的内侧;撑胀隔膜的内侧通过排气孔与外界连通;传动件设置于壳体上,弹性支承组件通过传动件连接于排气开关。上述的救生用水钥匙通过弹性支承组件抵持于撑胀隔膜的内侧,弹性支承组件通过自身弹力支撑起撑胀隔膜,配重块压制弹力丝使得撑胀隔膜贴紧于开孔区域而趋于稳定状态,从而能够更好减少误触发的情况发生。
