The invention relates to the field of life jackets, and particularly discloses a self-expanding life jacket which comprises a self-expanding life jacket body, an automatic inflator pump and an emergency air hose are arranged on the surface of the self-expanding life jacket body, a telescopic corrugated pipe is arranged at one end of the emergency air hose, and a hard pipe is arranged at one end of the telescopic corrugated pipe. The first section of the hard pipe is provided with a connecting hose, and one end of the connecting hose is provided with a hard pipe orifice ring; the self-expanding life jacket has the beneficial effects that the emergency air conveying hose is optimized, firstly, the telescopic corrugated pipe is additionally arranged to achieve length adjusting type optimization of the pipe body, the suspension push handle which is jacked and floated by liquid is additionally arranged in the hard pipe to be matched with the sealing block to block the baffle ring, and the air leakage phenomenon occurring when the emergency air conveying hose is adopted for blowing is avoided; and after the two sets of silica gel strips arranged in the connecting hose are extruded, the connecting hose is temporarily closed through press fit of the press fit strips and the press fit grooves, and the air leakage phenomenon of the connecting hose is avoided.

    本发明涉及救生衣领域,具体公开了一种自膨胀救生衣,包括自膨胀救生衣本体,自膨胀救生衣本体的表面设置有自动充气泵和应急输气软管,应急输气软管的一端设置有伸缩波纹管,伸缩波纹管的一端设置有硬质管,硬质管的第一段设置有连接软管,连接软管的一端设置有硬质管口环;有益效果为:本发明提出的自膨胀救生衣对应急输气软管进行优化,首先加配伸缩波纹管实现管体的长度调节式优化,且在硬质管内部加装被液体顶托浮起的悬浮推柄配合封块封堵挡环,避免采用应急输气软管吹气时出现漏气现象,并且连接软管内部配置的两组硅胶条被挤压后,通过压合条和压合槽压合,实现连接软管的暂时闭合,避免连接软管出现漏气现象。
