The invention discloses a portable lifeboat hand pump which comprises a hand pump cylinder and a hand handle located above the hand pump cylinder, the bottom of the hand pump cylinder is fixedly connected with a hollow seat through a ventilation cylinder, and the left end of the hollow seat is fixedly connected with an inflation pipe through an inflation connector; a lifting frame is further arranged between the hand pressing handle and the hand pressing type pump cylinder, a pressing rod is fixedly connected between the top of the lifting frame and the bottom of the hand pressing handle, and a piston rod is fixedly connected to the center of the bottom of the lifting frame. According to the invention, gas can be conveniently inflated into the lifeboat, and self-pressurization can be carried out through hand pressure operation, so that the inflation speed can be quicker, the disadvantage that a pressurization mechanism needs to be additionally arranged for quick inflation in the past is avoided, and meanwhile, the input cost is also reduced; the problem that in the prior art, due to the fact that inflation airflow is gentle, the air inlet speed is low is solved.

    本发明公开了一种便携式救生艇手压泵,包括手压式泵筒和位于手压式泵筒上方的手压把手,手压式泵筒的底部通过通气筒固定连接有空心座,且空心座的左端通过充气接口连接固定有充气管;所述手压把手与手压式泵筒之间还设有升降架,升降架的顶部与手压把手的底部之间固定连接有按压杆,升降架的底部中心处固定连接有活塞杆。本发明不仅便于将气体充气至救生艇内,而且通过手压操作即可自行进行增压,从而能够促使充气时的速度更快捷,避免以往还需额外增设增压机构才能快速充气的弊端,同时也减小了投入成本,解决了现有技术还存在充气气流由于较为平缓而导致进气速度较慢的问题。
