The invention relates to the technical field of portable inflatable lifesaving, in particular to multi-directional expansion type portable inflatable lifesaving equipment which comprises an external housing, a water immersion type elastic ejector pin and a steel gas storage tank with high-pressure carbon dioxide gas inside. According to the multidirectional expansion type portable inflatable lifesaving equipment, an annular air bag closed by a detachable fixing buckle is formed on the wrist of a user in a bidirectional expansion extrusion mode, the annular air bag can be used as a common life buoy after being expanded, use is quite easy and convenient, and time and labor are saved; by means of the detachable fixing buckles, people can conveniently wear the device, and the device is replaced and worn on a drowning person after being expanded, so that the floating effect is improved, and the use modes are more diversified; the water immersion type elastic ejector pin, the steel air storage tank, the folding type compression air bag and the outer cover shell are all of a split type detachable structural design, so that the device can be repeatedly used, the later use cost of the device is greatly reduced, and popularization and promotion are facilitated.
本发明涉及便携式充气救生技术领域,尤其是一种具有多向膨胀式随身充气救生设备,包括外部罩壳、水浸式弹性顶针和内置高压二氧化碳气体的钢制储气罐。本发明的一种具有多向膨胀式随身充气救生设备采用双向膨胀挤出的方式在使用者手腕部位形成一个由可拆卸式固定卡扣闭合的环形气囊,可以在膨胀之后作为常见的救生圈使用,使用十分简单方便,而且省时省力;利用可拆卸式固定卡扣可以方便人们佩戴,并且在膨胀后将其更换穿戴在落水者身上,从而提升漂浮效果,使用方式更加多样;水浸式弹性顶针、钢制储气罐和折叠式压缩气囊与外部罩壳之间均采用分体式可拆卸结构设计,使其可以多次重复利用,大大降低其后期使用成本,方便普及推广。
