The invention relates to the technical field of marine lifesaving, in particular to a life jacket with an automatic inflating and tightening buoyancy device, which comprises a lifesaving vest, a buoyancy foam block sewn on the outer side surface of the lifesaving vest and an automatic inflating device. According to the life jacket with the automatic inflating and tightening buoyancy device, a bottom supporting cover internally provided with an inflating air bag is connected to a bottom bandage at the lower end of a life vest, annular inner air bags are sewn to the inner sides of arm wearing openings in the two sides of the life vest, the supporting area of the bottom of a wearer is increased, and meanwhile the annular inner air bags expand and extrude out; an internal opening of the arm wearing opening is tightened, so that the wearing comfort is improved while the wearing stability of a person is ensured; solid sealing liquid is inserted into the connecting end of the internal air delivery pipe, and the solid sealing liquid is fused with water to form a cementing substance through automatic water encountering or manual pressing, so that the damaged end of the air bag is sealed and plugged, air leakage is avoided, and the safety of the life jacket is greatly improved.

    本发明涉及船用救生技术领域,尤其是一种具有自动充气收紧浮力装置的救生衣,包括救生背心、缝接在救生背心外侧面上的浮力泡沫块和自动充气装置。本发明的一种具有自动充气收紧浮力装置的救生衣在救生背心下端的底部绑带上连接有内置充气气囊的底部支撑罩,在救生背心两侧的手臂穿戴口内侧缝接有环形内部气囊,提升穿戴者底部的支撑面积,同时环形内部气囊膨胀挤出,收紧手臂穿戴口的内部开口,在保证人员穿戴稳定性的同时提升穿戴舒适度;在内部输气管连接端插接有固体密封液,通过自动遇水或者人工按压使其与水相融形成胶装物质,从而对气囊破损端进行密封填堵,从而避免泄气,大大提升救生衣的安全性。
