The invention discloses a portable necklace type life buoy, and relates to the technical field of life buoys. The portable necklace type life buoy comprises a main body, a starting mechanism, an inflating mechanism and a gas cylinder, the main body comprises a contact switch, one end of the contact switch is connected with a first airbag, and a first inflating groove is formed in the first airbag.By arranging a mounting block, during mounting, the mounting block is rotationally connected with the gas cylinder, in the mounting process, an ejector pin punctures the gas cylinder, gas in the gascylinder leaks out and is conveyed into a gas storage tank through a connecting pipe, and after a person carrying the life buoy falls into water, water enters the contact switch and meanwhile serves as a conducting medium to be communicated with a contact arranged in the contact switch; and a power supply is switched on to start a motor, the motor operates to drive a screw rod to rotate, the screwrod rotates to drive a piston to move until a gas inlet groove is exposed, gas enters the gas inlet groove and is conveyed to the first inflating groove and a second inflating groove through an inflating pipe in the gas inlet groove to inflate the airbag, and inflation of the life buoy is completed.

    本发明公开了一种便携项链式救生圈,涉及救生圈技术领域,包括主体、启动机构、充气机构与气瓶,所述主体包括触点开关,所述触点开关的一端连接有一号气囊,所述一号气囊的内部设置有一号充气槽。本发明通过设置安装块,进行安装时,将安装块与气瓶转动连接,安装过程中,顶针戳破气瓶,气瓶中的气体漏出,通过连接管传输到储气槽内,当携带人员落水后,水进入触点开关内,同时作为导电介质连通触点开关内设置的触点,接通电源启动电机,电机运转带动丝杆进行旋转,丝杆旋转带动活塞进行位移,直至露出进气槽,气体进入进气槽,通过进气槽内的充气管传送至一号充气槽和二号充气槽给气囊进行充气,完成救生圈的充气。
