Description

Technical Field

[0001] This utility model relates to the field of inflatable boat technology, specifically a novel handle for multi-chamber inflatable boats. Background Technology

[0002] An inflatable boat is a type of boat that inflates, mostly made of PVC, with handles fixed to its exterior for passengers to hold onto. To improve the safety and reliability of inflatable boats and to prevent sudden rupture of the air chambers and complete gas leakage, the inflatable boat is usually divided into multiple air chambers of similar volume using elastic partitions, each equipped with an inflation device.

[0003] Most existing multi-chamber inflatable boats have individual nozzles or inflation devices on each chamber, requiring users to inflate and deflate each chamber individually, which is inconvenient. Some multi-chamber inflatable boats use connecting devices on the bulkheads to link or separate the chambers; however, these connecting devices, built into the hull, require breaking down the hull for repairs in case of malfunction, which is time-consuming, labor-intensive, and costly, reducing the boat's lifespan. Furthermore, the nozzles and connecting devices on existing inflatable boats are all separate designs, resulting in high manufacturing costs and complex inflation / deflation operations.

[0004] Therefore, there is an urgent need for an inflatable boat handle that can inflate, deflate, and connect the air chamber. Utility Model Content

[0005] The purpose of this utility model is to provide a novel handle for multi-chamber inflatable boats.

[0006] A novel multi-chamber inflatable marine handle includes a handle body, which comprises a base plate and a C-shaped handle. The C-shaped handle has an inflation chamber and a connecting chamber at each end. The bottom of the base plate has a connecting channel between the inflation chamber and the connecting chamber. An inflation device is installed inside the inflation chamber, and a connecting device is installed inside the connecting chamber. A connecting sealing device is installed at the bottom of the connecting device, and a pressing device for controlling the raising and lowering of the connecting sealing device is installed at the top of the connecting device. The inflation device includes an outer inflation cylinder fixedly installed inside the inflation chamber. The interior of the outer inflation cylinder... The system is equipped with an inflatable base, an air inlet on the side wall of the inflatable base, an inner inflatable cylinder inside the inflatable base, an inflatable telescopic structure at the center of the inner inflatable cylinder, an inflatable valve plate fixedly installed at the bottom of the inflatable telescopic structure, an inflatable valve rod pressure plate installed at the top of the inflatable telescopic structure, an inflatable return spring sleeved on the outer side of the inner inflatable cylinder between the inflatable valve rod pressure plate and the inflatable base, an air outlet at the bottom of the inflatable base, an inflatable sealing gasket fixedly installed on the top of the inflatable valve plate to cooperate with the air outlet, and an inflatable outer cylinder cover detachably installed on the top of the outer inflatable cylinder.

[0007] Furthermore, the connecting device includes a mounting base and a mounting plate fixedly disposed on the outside of the mounting base. The mounting plate is sealed at the bottom of the connecting cavity. A pressing through hole is provided at the center of the interior of the mounting base, and a connecting hole is provided inside the mounting base outside the pressing through hole.

[0008] Furthermore, the connecting sealing device includes a connecting sealing plate, which is raised and lowered at the bottom of the mounting base by a pressing device, and a connecting sealing gasket that mates with the connecting hole is fixedly provided on the connecting sealing plate.

[0009] Furthermore, the pressing device includes a pressing outer shell fixedly disposed within the communicating cavity, a pressing seat fixedly disposed within the pressing outer shell, a limiting groove formed on the side wall of the pressing seat, a pressing inner cylinder movably disposed within the pressing seat, a pressing handle fixedly disposed at the top of the pressing inner cylinder, a limiting block fixedly disposed on the side wall of the pressing inner cylinder that cooperates with the limiting groove, an upper pressing rod fixedly disposed at the bottom center of the pressing handle that penetrates the pressing inner cylinder, a pressing elastic sealing plate disposed below the pressing outer shell that is sealed to the communicating cavity and connected to the bottom of the upper pressing rod, a lower pressing rod fixedly disposed at the bottom center of the pressing elastic sealing plate that cooperates with the upper pressing rod, the middle part of the lower pressing rod penetrating the middle part of the communicating sealing plate and fixedly connected thereto, and the bottom of the lower pressing rod pressing through a through hole and slidingly connected thereto.

[0010] Furthermore, the pressing device includes a telescopic shaft motor fixedly mounted on the top of the mounting base. The output end of the telescopic shaft motor is fixedly provided with a telescopic connecting shaft. The telescopic connecting shaft passes through the pressing through hole and is slidably connected thereto. The lower end of the telescopic connecting shaft is fixedly connected to the connecting sealing plate. The top of the connecting cavity is sealed with a pressing sealing cover.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention avoids the need to individually inflate and deflate multiple air chambers, and also avoids the need to damage the inflatable hull when the connecting device malfunctions and requires repair or replacement. This invention allows for repair or replacement simply by separating the handle body from the inflatable hull, making operation convenient, time-saving, and labor-saving, reducing repair and replacement costs, and extending the service life of the inflatable hull. This invention integrates inflation / deflation and connecting functions into the handle body, giving it the functions of inflating, deflation, and connecting air chambers in addition to its handheld function.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Example 1

[0035] The following is in conjunction with the appendix Figure 1-3 Appendix Figure 7-14 and attached Figure 18 The present invention will be further described as follows:

[0036] A novel multi-chamber inflatable marine handle includes a handle body 1, which includes a base plate 101 and a C-shaped handle 102. The two ends of the C-shaped handle 102 are respectively provided with an inflation chamber 2 and a connecting chamber 3. The bottom of the base plate 101 is provided with a connecting channel 4 connecting the inflation chamber 2 and the connecting chamber 3. An inflation device 5 is provided in the inflation chamber 2, and a connecting device 6 is provided in the connecting chamber 3. A connecting sealing device 8 is provided at the bottom of the connecting device 6, and a pressing device 7 is provided at the top of the connecting device 6 to control the raising and lowering of the connecting sealing device 8.

[0037] In this embodiment, the interior of the inflatable hull 9 is divided into multiple air chambers 11 by a partition 10. The bottom plate 101 is bonded and fixedly connected to the exterior of the inflatable hull 9 above the partition 10. The inflation chamber 2 and the connecting chamber 3 are respectively connected to two air chambers 11 on both sides of the same partition 10. The connecting channel 4 is used to connect the inflation chamber 2 and the connecting chamber 3.

[0038] Press the inflation device 5 to connect the inflation chamber 2 with the air chamber 11 it contains. Insert the nozzle of the inflation / deflation pump into the inflation chamber 2 and start the inflation / deflation pump to inflate or deflate the air chamber 11. After inflation or deflation is complete, remove the nozzle of the inflation / deflation pump from the inflation chamber 2. Press the inflation device 5 to seal the inflation chamber 2 with the air chamber 11 it contains, so that the air in the air chamber 11 will not be discharged from the inflation chamber 2.

[0039] By controlling the movement of the connecting sealing device 8 through the pressing device 7, the connecting sealing device 8 no longer seals the connecting device 6. At this time, the inflation chamber 2 and the connecting chamber 3 are connected through the connecting channel 4, that is, the two air chambers 11 on both sides of the same partition 10 are connected, and the air in one air chamber 11 can enter the other air chamber 11 through the connecting channel 4, so that the two air chambers 11 can be inflated or deflated at the same time.

[0040] After inflation or deflation, the connecting sealing device 8 is moved in the opposite direction by the pressing device 7, and the connecting sealing device 8 seals the connecting device 6. At this time, the inflation chamber 2 and the connecting chamber 3 cannot be connected through the connecting channel 4, that is, the two air chambers 11 on both sides of the same partition 10 are independent of each other.

[0041] The inflation device 5 includes an outer inflation cylinder 501 fixedly installed in the inflation chamber 2. An inflation seat 502 is installed inside the outer inflation cylinder 501. An air inlet 503 is opened on the side wall of the inflation seat 502. An inner inflation cylinder 504 is installed inside the inflation seat 502. An inflation telescopic structure 505 is installed at the center of the inner inflation cylinder 504. An inflation valve plate 507 is fixedly installed at the bottom of the inflation telescopic structure 505. An inflation valve rod pressure plate 510 is installed at the top of the inflation telescopic structure 505. An inflation return spring 506 is sleeved on the outside of the inner inflation cylinder 504 between the inflation valve rod pressure plate 510 and the inflation seat 502. An air outlet 508 is opened at the bottom of the inflation seat 502. An inflation sealing gasket 509 that cooperates with the air outlet 508 is fixedly installed at the top of the inflation valve plate 507. An outer inflation cylinder cover 511 is detachably installed on the top of the outer inflation cylinder 501.

[0042] In this embodiment, the outer cylinder cover 511 is opened, and the top of the inflatable telescopic structure 505 is pressed by the inflatable valve rod pressure plate 510. The inflatable telescopic structure 505 drives the inflatable valve plate 507 to move downward, and the position of the inflatable valve plate 507 is fixed by the structure of the inflatable telescopic structure 505 itself, and the inflatable sealing gasket 509 no longer seals the air outlet 508. At this time, the inflatable return spring 506 is in a compressed state. Preferably, the inflatable telescopic structure 505 is the telescopic mechanism of a press-type ballpoint pen. Its application in this application will not be described in detail.

[0043] When the air nozzle of the inflation / deflation pump is inserted into the inflation chamber 2 and the pump is started for inflation, air enters the gap between the inflation seat 502 and the inner inflation cylinder 504 from the air inlet 503, and then exits from the air outlet 508 into the air chamber 11. When the pump is started for deflation, air in the air chamber 11 enters the gap between the inflation seat 502 and the inner inflation cylinder 504 from the air outlet 508, and then exits from the air inlet 503.

[0044] After inflation and deflation are completed, the top of the inflation telescopic structure 505 is pressed by the inflation valve rod pressure plate 510. The inflation reset spring 506 extends and drives the inflation telescopic structure 505 and the inflation valve plate 507 to move downward. The inflation sealing gasket 509 seals the air outlet 508. Finally, the inflation outer cylinder cover 511 is installed.

[0045] The connecting device 6 includes a mounting base 602 and a mounting plate 601 fixedly disposed on the outside of the mounting base 602. The mounting plate 601 is sealed at the bottom of the connecting cavity 3. A pressing through hole 603 is provided at the center of the interior of the mounting base 602. A connecting hole 604 is provided inside the mounting base 602 outside the pressing through hole 603.

[0046] The connecting sealing device 8 includes a connecting sealing plate 801, which is raised and lowered at the bottom of the mounting base 602 by a pressing device 7. A connecting sealing gasket 802 that mates with the connecting hole 604 is fixedly provided at the bottom of the connecting sealing plate 801.

[0047] The pressing device 7 includes a pressing outer shell 701 fixedly disposed within the communicating cavity 3. A pressing seat 702 is fixedly disposed within the pressing outer shell 701. A limiting groove 703 is formed on the side wall of the pressing seat 702. A pressing inner cylinder 705 is movably disposed within the pressing seat 702. A pressing handle 704 is fixedly disposed on the top of the pressing inner cylinder 705. A limiting block 706 that cooperates with the limiting groove 703 is fixedly disposed on the side wall of the pressing inner cylinder 705. A through pressing mechanism is fixedly disposed at the bottom center of the pressing handle 704. The inner cylinder 705 has an upper pressing rod 707. The lower part of the pressing outer shell 701 is provided with a pressing elastic sealing plate 708 that is sealed to the communicating cavity 3 and connected to the bottom of the upper pressing rod 707. The bottom center of the pressing elastic sealing plate 708 is fixedly provided with a lower pressing rod 709 that cooperates with the upper pressing rod 707. The middle part of the lower pressing rod 709 passes through the middle part of the communicating sealing plate 801 and is fixedly connected to it. The bottom of the lower pressing rod 709 presses through the hole 603 and is slidably connected to it.

[0048] In this embodiment, pressing and rotating the outer casing 701 causes the inner cylinder 705 to move synchronously with the outer casing 701, driving the limiting block 706 to move upward and rotate along the limiting groove 703 to the uppermost part of the limiting groove 703 and defining its position. The upper pressing rod 707 moves upward with the outer casing 701 and no longer presses the middle of the pressing elastic sealing plate 708 or the top of the lower pressing rod 709. The pressing elastic sealing plate 708 returns to its original position. Figure 14 The original shape is shown, and the pressing rod 709 slides upward along the pressing through hole 603. The pressing rod 709 causes the connecting sealing plate 801 to move upward, and the connecting sealing gasket 802 moves upward and no longer seals the connecting hole 604.

[0049] When the air pump is started to inflate the air chamber 11 where the inflation chamber 2 is located, the air can enter the connecting chamber 3 above the mounting plate 601 through the inflation chamber 2 and the connecting channel 4, and then be discharged from the connecting hole 604 into the air chamber 11 where the connecting chamber 3 is located, thus realizing the inflation of multiple air chambers 11.

[0050] When the air pump is started to release air from the air chamber 11 where the air chamber 2 is located, the air in the air chamber 11 where the connecting device 6 is located enters the air chamber 11 where the connecting chamber 3 is located through the connecting hole 604, the connecting chamber 3, the connecting channel 4, and the air chamber 2, and is then extracted by the air pump.

[0051] After inflation and deflation are completed, press down and rotate the outer casing 701. The inner cylinder 705 moves synchronously with the outer casing 701, causing the limiting block 706 to move downward and rotate along the limiting groove 703 to the lowest point of the limiting groove 703, thus limiting its position. The upper pressing rod 707 moves downward with the outer casing 701, pressing the middle of the elastic sealing plate 708 and the top of the lower pressing rod 709. The middle of the elastic sealing plate 708 undergoes a process similar to... Figure 13 The deformation shown causes the pressing rod 709 to slide downwards along the pressing through hole 603. The pressing rod 709 causes the connecting sealing plate 801 to move downwards, and the connecting sealing gasket 802 moves downwards to seal the connecting hole 604. At this time, the air chamber 11 where the inflation chamber 2 is located cannot communicate with the air chamber 11 where the connecting chamber 3 is located through the connecting channel 4.

[0052] Example 2

[0053] The following is in conjunction with the appendix Figure 4-9 Appendix Figure 15-17 and attached Figure 19 The present invention will be further described as follows:

[0054] A novel multi-chamber inflatable marine handle includes a handle body 1, which includes a base plate 101 and a C-shaped handle 102. The two ends of the C-shaped handle 102 are respectively provided with an inflation chamber 2 and a connecting chamber 3. The bottom of the base plate 101 is provided with a connecting channel 4 connecting the inflation chamber 2 and the connecting chamber 3. An inflation device 5 is provided in the inflation chamber 2, and a connecting device 6 is provided in the connecting chamber 3. A connecting sealing device 8 is provided at the bottom of the connecting device 6, and a pressing device 7 is provided at the top of the connecting device 6 to control the raising and lowering of the connecting sealing device 8.

[0055] In this embodiment, the interior of the inflatable hull 9 is divided into multiple air chambers 11 by a partition 10. The bottom plate 101 is bonded and fixedly connected to the exterior of the inflatable hull 9 above the partition 10. The inflation chamber 2 and the connecting chamber 3 are respectively connected to two air chambers 11 on both sides of the same partition 10. The connecting channel 4 is used to connect the inflation chamber 2 and the connecting chamber 3.

[0056] Press the inflation device 5 to connect the inflation chamber 2 with the air chamber 11 it contains. Insert the nozzle of the inflation / deflation pump into the inflation chamber 2 and start the inflation / deflation pump to inflate or deflate the air chamber 11. After inflation or deflation is complete, remove the nozzle of the inflation / deflation pump from the inflation chamber 2. Press the inflation device 5 to seal the inflation chamber 2 with the air chamber 11 it contains, so that the air in the air chamber 11 will not be discharged from the inflation chamber 2.

[0057] By controlling the movement of the connecting sealing device 8 through the pressing device 7, the connecting sealing device 8 no longer seals the connecting device 6. At this time, the inflation chamber 2 and the connecting chamber 3 are connected through the connecting channel 4, that is, the two air chambers 11 on both sides of the same partition 10 are connected, and the air in one air chamber 11 can enter the other air chamber 11 through the connecting channel 4, so that the two air chambers 11 can be inflated or deflated at the same time.

[0058] After inflation or deflation, the connecting sealing device 8 is moved in the opposite direction by the pressing device 7, and the connecting sealing device 8 seals the connecting device 6. At this time, the inflation chamber 2 and the connecting chamber 3 cannot be connected through the connecting channel 4, that is, the two air chambers 11 on both sides of the same partition 10 are independent of each other.

[0059] The inflation device 5 includes an outer inflation cylinder 501 fixedly installed in the inflation chamber 2. An inflation seat 502 is installed inside the outer inflation cylinder 501. An air inlet 503 is opened on the side wall of the inflation seat 502. An inner inflation cylinder 504 is installed inside the inflation seat 502. An inflation telescopic structure 505 is installed at the center of the inner inflation cylinder 504. An inflation valve plate 507 is fixedly installed at the bottom of the inflation telescopic structure 505. An inflation valve rod pressure plate 510 is installed at the top of the inflation telescopic structure 505. An inflation return spring 506 is sleeved on the outside of the inner inflation cylinder 504 between the inflation valve rod pressure plate 510 and the inflation seat 502. An air outlet 508 is opened at the bottom of the inflation seat 502. An inflation sealing gasket 509 that cooperates with the air outlet 508 is fixedly installed at the top of the inflation valve plate 507. An outer inflation cylinder cover 511 is detachably installed on the top of the outer inflation cylinder 501.

[0060] In this embodiment, the outer cylinder cover 511 is opened, and the top of the inflatable telescopic structure 505 is pressed by the inflatable valve rod pressure plate 510. The inflatable telescopic structure 505 drives the inflatable valve plate 507 to move downward, and the position of the inflatable valve plate 507 is fixed by the structure of the inflatable telescopic structure 505 itself, and the inflatable sealing gasket 509 no longer seals the air outlet 508. At this time, the inflatable return spring 506 is in a compressed state. Preferably, the inflatable telescopic structure 505 is the telescopic mechanism of a press-type ballpoint pen. Its application in this application will not be described in detail.

[0061] When the air nozzle of the inflation / deflation pump is inserted into the inflation chamber 2 and the pump is started for inflation, air enters the gap between the inflation seat 502 and the inner inflation cylinder 504 from the air inlet 503, and then exits from the air outlet 508 into the air chamber 11. When the pump is started for deflation, air in the air chamber 11 enters the gap between the inflation seat 502 and the inner inflation cylinder 504 from the air outlet 508, and then exits from the air inlet 503.

[0062] After inflation and deflation are completed, the top of the inflation telescopic structure 505 is pressed by the inflation valve rod pressure plate 510. The inflation reset spring 506 extends and drives the inflation telescopic structure 505 and the inflation valve plate 507 to move downward. The inflation sealing gasket 509 seals the air outlet 508. Finally, the inflation outer cylinder cover 511 is installed.

[0063] The connecting device 6 includes a mounting base 602 and a mounting plate 601 fixedly disposed on the outside of the mounting base 602. The mounting plate 601 is sealed at the bottom of the connecting cavity 3. A pressing through hole 603 is provided at the center of the interior of the mounting base 602. A connecting hole 604 is provided inside the mounting base 602 outside the pressing through hole 603.

[0064] The connecting sealing device 8 includes a connecting sealing plate 801, which is raised and lowered at the bottom of the mounting base 602 by a pressing device 7. A connecting sealing gasket 802 that mates with the connecting hole 604 is fixedly provided at the bottom of the connecting sealing plate 801.

[0065] The pressing device 7 includes a telescopic shaft motor 710 fixedly installed on the top of the mounting base 602. The output end of the telescopic shaft motor 710 is fixedly provided with a telescopic connecting shaft 711. The telescopic connecting shaft 711 passes through the pressing through hole 603 and is slidably connected thereto. The lower end of the telescopic connecting shaft 711 is fixedly connected to the connecting sealing plate 801. The top of the connecting cavity 3 is sealed with a pressing sealing cover.

[0066] In this embodiment, the output end of the telescopic shaft motor 710 is extended, and the telescopic connecting shaft 711 drives the connecting sealing plate 801 to move downward, so that the connecting sealing gasket 802 no longer seals the connecting hole 604.

[0067] When the air pump is started to inflate the air chamber 11 where the inflation chamber 2 is located, the air can enter the connecting chamber 3 above the mounting plate 601 through the inflation chamber 2 and the connecting channel 4, and then be discharged from the connecting hole 604 into the air chamber 11 where the connecting chamber 3 is located, thus realizing the inflation of multiple air chambers 11.

[0068] When the air pump is started to release air from the air chamber 11 where the air chamber 2 is located, the air in the air chamber 11 where the connecting device 6 is located enters the air chamber 11 where the connecting chamber 3 is located through the connecting hole 604, the connecting chamber 3, the connecting channel 4, and the air chamber 2, and is then extracted by the air pump.

[0069] After inflation and deflation are completed, the output end of the telescopic shaft motor 710 retracts, and the telescopic connecting shaft 711 drives the connecting sealing plate 801 to move upward, and the connecting sealing gasket 802 seals the connecting hole 604. At this time, the air chamber 11 where the inflation chamber 2 is located cannot communicate with the air chamber 11 where the connecting chamber 3 is located through the connecting channel 4.
