Detailed Description

Referring to the attached drawings 1-2, an inflatable life buoy comprises an inflating device 2 connected with a life buoy 1, the inflating device 2 and the life buoy 1 are fixedly connected through a rubber hose 3, a one-way valve 4 is fixedly installed on one side, close to the inflating device 2, of the rubber hose 3, the inflating device 2 comprises a valve body 5, water injection holes 6 extending to the inside are formed in two sides of the valve body 5, an effervescent tablet 8 connected with a thimble fixing block 7 is arranged at one end of each water injection hole 6, a gas cylinder 11 connected with a sealing gasket 10 is installed at the center of the bottom end of the thimble fixing block 7 through a tip 9, a set screw 12 connected with the inner wall of the valve body 5 is fixedly installed on one side, close to the one-way valve 4, between the tip 9 and the thimble fixing block 7, balls 14 connected with a sliding block 13 are fixedly installed on two sides of the top end of the thimble fixing block 7, one side of the outer wall of the sliding block 13 is connected with a spring 16 arranged on a threaded cap 15, the threaded cap 15 is connected with the valve body 5 through rotation fixing, a threaded groove connected with the threaded cap 15 is formed in one side of the inner wall of the valve body 5 along the height direction of the spring 16, and extrusion cavities are formed among the inner wall of the threaded cap 15, the valve body 5 and the spring 16.

The specific embodiment of the scheme is that one end of the rubber hose 3 is connected to the valve body 5 through threads, white adhesive tape cloth is wound on the threaded connection part to realize thread sealing, the other end of the rubber hose is connected to the life buoy 1, and the disassembly and the assembly between structural members can be facilitated through the threaded connection and fixation mode.

The specific embodiment of this scheme is, when compressing the spring through the screw thread of screwing, can appear because there is great sliding friction power between spring and the fixed block, and then produces great friction torque, and when the moment of torsion was too big, the fixed block was difficult to the gliding. When the problem occurs, the twisting deformation of the sliding block is caused, the disc can rotate, the torque of the spring can be timely released, a ball device is additionally arranged between the sliding block and the spring, the torque of the spring is released by the rolling of the ball, and the sliding friction is replaced by the rolling friction, so that the torque generated by the friction is reduced to the maximum extent, and the effect is good.

The specific embodiment of the scheme is that the dry effervescent tablets have certain strength, and the strength is rapidly weakened when the effervescent tablets are rapidly dissolved in water, so that the compression spring can be released in time, enough impact force is generated to puncture the high-pressure gas bottle, then gas is released, and the annular gas bag is filled with the gas.

The concrete embodiment of this scheme does, 4 outer wall one sides of check valve are close to the rubber hose 3 on the cup joint be fixed with the sealing washer, 11 outsides of gas cylinder are cylindrical settings, and adopt the paper carbon steel sheet to make, valve body 5 adopts hard aluminum alloy to make.

The specific embodiment of the scheme is that the inflation inlet of the lifebuoy 1 is provided with the one-way valve 4, so that gas backflow cannot occur in the filling process, and a good sealing protection effect can be achieved after the lifebuoy is filled, which is a key step for realizing sealing, and on one hand, depending on the quality of the lifebuoy 1, whether the one-way valve 4 can play a good role or not is achieved; on the other hand, the sealing reliability of the connection portion is realized by the function of the valve body 5.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
