Detailed Implementation

[0025] Example: Figures 1-5 As shown, an embodiment of the present invention provides a multi-chamber inflatable boat, including an inflatable hull 1, a partition 2, an arc-shaped air chamber 3, a cylindrical air chamber 4, and an inflation / deflation assembly. The partition 2 is fixedly provided inside the air bladder of the inflatable hull 1, so that the air bladder forms an arc-shaped air chamber 3 and two cylindrical air chambers 4. The inflation / deflation assembly is installed on the inflatable hull 1.

[0026] The inflation / deflation assembly includes an inflation / deflation pipe 5 and a connecting pipe 6. Three connecting pipes 6 are installed through the lower side of the inflation / deflation pipe 5, and the other end of the connecting pipe 6 passes through the arc-shaped gas chamber 3 and two cylindrical gas chambers 4 respectively. An auxiliary inflation / deflation assembly is installed inside the inflation / deflation pipe 5, and a sealing assembly to prevent gas leakage from the gas chamber is installed inside the connecting pipe 6.

[0027] In this embodiment, the auxiliary inflation / deflation assembly includes an external threaded post 7, an inflation / deflation hole 8, a hexagonal head 9, and a limiting arc ring 10. The external threaded post 7 is threaded to the upper inner side of the inflation / deflation pipe 5. An inflation / deflation hole 8 is provided in the center of the external threaded post 7. A hexagonal head 9 is provided through the external threaded post 7. A limiting arc ring 10 is sleeved on the external threaded post 7.

[0028] In this embodiment, the sealing assembly includes a fixing rod 601, a rubber ring 602, a guide rod 603, a rubber disc 604, a sleeve spring 605, and a compression block 606. The fixing rod 601 is located at the end of the connecting pipe 6 near the inflation / deflation pipe 5. The rubber ring 602 is installed on the left side inside the connecting pipe 6. The guide rod 603 is provided through the fixing rod 601. The rubber disc 604 is fixedly provided at the left end of the guide rod 603. The sleeve spring 605 is fixedly provided between the rubber disc 604 and the fixing rod 601. The compression block 606 is fixedly provided at the right end of the guide rod 603.

[0029] In this embodiment, the diameter of the rubber disc 604 is larger than the diameter of the central through hole of the rubber ring 602, smaller than the inner diameter of the connecting tube 6, and the sleeve spring 605 is in a stretched state, with the rubber disc 604 tightly attached to the rubber ring 602.

[0030] In this embodiment, the extrusion block 606 extends out of the connecting pipe 6 and into the inflation / deflation pipe 5, so that the external threaded post 7 can contact and push the extrusion block.

[0031] In this embodiment, the bottom of the external threaded column 7 is a boss-shaped part with a gradually decreasing diameter. When the bottom of the hexagonal head 9 is attached to the upper surface of the limiting arc ring 10, the horizontal height of the boss-shaped part at the bottom of the external threaded column 7 is higher than the horizontal height of the extrusion block 606. When the bottom of the hexagonal head 9 is attached to the upper surface of the inflation / deflation pipe 5, the horizontal height of the boss-shaped part at the bottom of the external threaded column 7 is lower than the horizontal height of the extrusion block 606. This facilitates the external threaded column 7 to push the extrusion block 606 to move inward toward the connecting pipe 6, so that the rubber disc 604 separates from the rubber ring 602, thereby achieving the effect of deflation.

[0032] In this embodiment, the opening arc of the limiting arc ring 10 is 120°-150°, and the limiting arc ring 10 is made of rubber material, which facilitates the positioning of the limiting arc ring 10 at the depth of the threaded connection between the external threaded post 7 and the inflation / deflation pipe 5, and also facilitates the removal of the limiting arc ring 10.

[0033] By incorporating an inflation / deflation assembly, an auxiliary inflation / deflation assembly, and a sealing assembly, when inflating the arc-shaped air chamber 3 and the two cylindrical air chambers 4, the external inflation mechanism connects to the inflation / deflation port 8 on the auxiliary inflation / deflation assembly. The inflation / deflation port 8 injects external gas into the inflation / deflation pipe 5, increasing the air pressure within the pipe. This air pressure impacts the three rubber discs 604 within the three connecting pipes 6, causing the rubber discs 604 to separate from the rubber rings 602. The sleeve spring 605 is then in a re-stretched state, allowing the high-pressure gas in the inflation / deflation pipe 5 to be injected into the air chambers connected by the connecting pipes 6, achieving simultaneous inflation of multiple air chambers. After evacuation, the rebound force of the sleeve spring 605 causes the rubber discs 604 to adhere tightly to the surface of the rubber rings 602, effectively sealing the central through hole of the rubber rings 602. This seals the connecting pipes 6, preventing gas from escaping from the air chambers. The operation is simple and convenient.

[0034] When it is necessary to release the gas in the gas chamber, the limiting arc ring 10 is removed, and then the external threaded column 7 is turned by the hexagonal head 9, so that the external threaded column 7 moves downward along the filling and discharging pipe 5. The frustum part at the bottom of the external threaded column 7 contacts the compression block 606 on the three sealing components, and squeezes the compression block 606 into the connecting pipe 6. The compression block 606 pushes the rubber disc 604 and the rubber ring 602 to separate through the guide rod 603, contacting the sealing components to seal the connecting pipe 6, and then squeezes multiple gas chambers. The gas in the gas chamber is discharged from the connecting pipe 6 into the filling and discharging pipe 5, realizing the effect of simultaneous exhaust of multiple gas chambers. After the external threaded column 7 squeezes the compression block 606 into the connecting pipe 6, the gas in multiple gas chambers can also be extracted simultaneously by connecting the filling and discharging port 8 through the external air extraction device, increasing practicality.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
