[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 9 shown, the embodiment of the present invention provides a gas cylinder assembly for an underwater delivery training device, including an underwater training device 1. Mounting frames 2 are fixedly installed on both sides inside the underwater training device 1. A driving motor 3 is fixedly installed inside the mounting frame 2. One end of the output shaft of the driving motor 3 is fixedly sleeved with a lead screw 4. The other end of the lead screw 4 penetrates through the mounting frame 2 and extends to the outside of the mounting frame 2 and is threadedly sleeved with a support frame 5. A groove 6 is opened inside the mounting frame 2 on the left side of the lead screw 4. A clamp 1 7 is movably sleeved inside the groove 6. The front of the clamp 1 7 extends to the outside of the mounting frame 2. A notch 8 is opened inside the mounting frame 2 on the right side of the lead screw 4. A movable plate 9 is movably sleeved inside the notch 8. A power motor 10 is fixedly installed inside the mounting frame 2 above the movable plate 9. One end of the output shaft of the power motor 10 is fixedly sleeved with a connecting rod 11. The other end of the connecting rod 11 penetrates through the mounting frame 2 and extends into the notch 8 and is fixedly sleeved with a gear 12. The outer surface of the gear 12 is meshed with the back of the movable plate 9. A slot hole 13 is opened on the front of the movable plate 9. A clamp 2 14 located outside the mounting frame 2 is movably sleeved inside the slot hole 13. Limiting blocks 24 are fixedly installed above and below the movable plate 9. The outer surfaces of the limiting blocks 24 are movably sleeved with the inner walls of the notch 8. An oxygen cylinder 30 is movably installed inside the inner walls of the clamp 1 7 and the clamp 2 14.

[0029] Among them, when the operator starts the power motor 10, it will drive the gear 12 to rotate through the connecting rod 11. Then, due to the meshing between the outer surface of the gear 12 and the back surface of the movable plate 9, the movable plate 9 will be driven to move through the gear 12. At the same time, the fixture two 14 will be driven to move through the movable plate 9, so that it moves a certain distance, releases the blockage of the oxygen cylinder 30 above the support frame 5, and starts the drive motor 3, which will drive the support frame 5 to move upward through the lead screw 4, so that it moves to the right side of the fixture one 7. Then, the power motor 10 drives the movable plate 9 and the fixture two 14 to reset, so that the oxygen cylinder 30 is driven to move into the fixture one 7 through the fixture two 14, thus facilitating the operator to clamp the oxygen cylinder 30 through the fixture one 7 and the fixture two 14, making it convenient to install the oxygen cylinder 30 and bringing convenience to the operator's use.

[0030] As Figure 9 shown, a card slot 15 located on the left side of the notch 8 is opened inside the mounting frame 2. A connecting block 16 is fixedly installed on the left side of the movable plate 9, and the left side of the connecting block 16 penetrates through the mounting frame 2 and extends into the inside of the card slot 15.

[0031] Among them, when the movable plate 9 moves, it will drive the connecting block 16 to move through the movable plate 9, so that the moving plate 18 will be driven to move through the connecting block 16, making it convenient to block the support frame 5, so that the operator does not need to adjust the position and height of the support frame 5 multiple times, making it convenient to install the oxygen cylinder 30.

[0032] As Figure 9 shown, fixing rods 17 located above and below the connecting block 16 are fixedly installed inside the card slot 15. A moving plate 18 is movably sleeved on the outer surface of the fixing rod 17. The front surface of the moving plate 18 extends to the outer wall of the mounting frame 2, and the back surface of the moving plate 18 is movably connected to the front surface of the connecting block 16.

[0033] Among them, due to the design of the fixing rod 17, the moving plate 18 will have a good limiting effect when moving, preventing it from shifting in position and bringing convenience to the operator's use.

[0034] As Figure 9 shown, a flexible spring 19 is movably sleeved on the outer surface of the fixing rod 17. One end of the flexible spring 19 is fixedly connected to the back surface of the moving plate 18, and the other end of the flexible spring 19 is fixedly connected to the inner wall of the card slot 15.

[0035] Among them, at this time, since the flexible spring 19 is in a stretched state, it will exert a backward pressure on the moving plate 18, thereby facilitating the reset of the moving plate 18.

[0036] As Figure 5 and Figure 9As shown, a first clamping block 20 is fixedly installed on the inner wall of the slot hole 13, and the right side of the first clamping block 20 penetrates through the second clamp 14 and extends into the interior of the second clamp 14.

[0037] Among them, due to the design of the first clamping block 20, it will facilitate the operator to position the second clamp 14, making it convenient to install the second clamps 14 of different sizes subsequently, so that it can fix oxygen cylinders 30 of different sizes.

[0038] Such as Figure 5 and Figure 9 As shown, a moving block 21 is movably sleeved inside the slot hole 13. A second clamping block 22 is fixedly installed on the left side of the moving block 21, and the left side of the second clamping block 22 penetrates through the second clamp 14 and extends into the interior of the second clamp 14.

[0039] Among them, due to the design of the moving block 21, it will facilitate blocking the second clamp 14, so that the second clamp 14 can be limited by the second clamping block 22, making it convenient to install the second clamp 14, and thus facilitating the replacement of the second clamps 14 of different sizes.

[0040] Such as Figure 9 As shown, a first bolt 23 is threadedly sleeved on the front surface of the moving block 21, and the back surface of the first bolt 23 penetrates through the moving block 21 and the movable plate 9 respectively and extends into the interior of the movable plate 9.

[0041] Among them, when the operator rotates the first bolt 23, the first bolt 23 will move out of the interior of the movable plate 9, releasing the fixation on the moving block 21, and then pulling the moving block 21 to the right, driving the second clamping block 22 to move out of the interior of the second clamp 14, releasing the fixation on the second clamp 14, thus facilitating the operator to replace the second clamp 14.

[0042] Such as Figure 4 and Figure 7 As shown, a stop block 25 is movably sleeved inside the groove 6 on the right side of the first clamp 7. A second bolt 26 is threadedly sleeved on the front surface of the stop block 25, and the back surface of the second bolt 26 penetrates through the stop block 25 and the mounting bracket 2 respectively and extends into the interior of the mounting bracket 2.

[0043] Among them, when the operator rotates the second bolt 26, the fixation on the stop block 25 will be released, and then the stop block 25 is pulled out of the interior of the groove 6, releasing the block on the first clamp 7, thus facilitating the replacement of the first clamps 7 of different sizes, so that oxygen cylinders 30 of different sizes can be installed.

[0044] Such as Figure 2 As shown, movable doors 27 are movably installed on both sides of the underwater training device 1. Fixed brackets 28 are fixedly installed on the front and rear sides of the inner wall of the underwater training device 1. A mouthpiece respirator 29 is fixedly installed on the front surface of the fixed bracket 28, and the outside of the mouthpiece respirator 29 is movably clamped to the right side of the oxygen cylinder 30 through a conduit.

[0045] Among them, due to the design of the mouthpiece respirator 29, it will facilitate the operator to absorb the oxygen inside the oxygen cylinder 30, making it convenient for underwater training.

[0046] Working principle and usage process:

[0047] First, when the operator replaces the oxygen cylinder 30 inside the underwater training device, the drive motor 3 is started at this time. The operation of the drive motor 3 will drive the support frame 5 to move through the lead screw 4, so that the support frame 5 is driven to contact the oxygen cylinder 30 at the bottom. Then, the lower power motor 10 is started. The operation of the power motor 10 will drive the gear 12 to rotate through the connecting rod 11. Furthermore, due to the meshing between the outer surface of the gear 12 and the back surface of the movable plate 9, the gear 12 will drive the movable plate 9 and the limit block 24 to move inside the notch 8. At the same time, due to the design of the limit block 24, the movable plate 9 has a good limiting effect when moving, preventing it from shifting in position. And the movable plate 9 drives the fixture two 14 and the connecting block 16 to move, so as to release the socket connection of the oxygen cylinder 30. At the same time, the connecting block 16 drives the moving plate 18 to move. Subsequently, the oxygen cylinder 30 falls above the support frame 5, making it convenient to remove the oxygen cylinder 30 from the fixture one 7, releasing the clamping of the bottom oxygen cylinder 30, and then disassembling it from bottom to top in turn. At the same time, when installing the replaced oxygen cylinder 30, the support frame 5 drives the oxygen cylinder 30 to be installed from top to bottom in turn, and the fixture two 14 is driven by the movable plate 9 to fix the replaced oxygen cylinder 30, thus facilitating the operator to replace the oxygen cylinder 30 and bringing convenience to the operator's use.

[0048] Then, when the operator installs the oxygen cylinder 30, the movable plate 9 drives the connecting block 16 to move at this time. Then, when installing the oxygen cylinder 30 on that layer, the connecting block 16 squeezes the moving plate 18, driving the moving plate 18 to move on the outer surface of the fixed rod 17. At the same time, the moving plate 18 is driven to move out of the card slot 15. And when the support frame 5 drives the oxygen cylinder 30 to move upward, the moving plate 18 blocks it. Subsequently, the support frame 5 and the oxygen cylinder 30 will move to the inside of the fixture one 7 and the fixture two 14, making it convenient to install the oxygen cylinder 30. Then, the oxygen cylinder 30 is installed from top to bottom in turn. At the same time, due to the elastic force of the flexible spring 19, when the connecting block 16 releases the extrusion of the moving plate 18, the moving plate 18 is driven to reset, thus facilitating the operator to improve the installation efficiency of the oxygen cylinder 30 and making it unnecessary to adjust the support frame 5 multiple times, bringing convenience to the operator's use.

[0049] After that, when the operator replaces the second fixture 14 and the first fixture 7, the movable plate 9 is driven to move out from the inside of the notch 8. At the same time, the oxygen cylinder 30 installed on the mounting frame 2 is disassembled. Then, the first bolt 23 is rotated to drive the first bolt 23 to move out from the inside of the movable plate 9, so as to release the fixation of the moving block 21. And the moving block 21 is pulled to drive the second clamping block 22 to move out from the inside of the second fixture 14, so as to release the clamping connection of the second fixture 14. Then, the second fixture 14 is pulled to drive the second fixture 14 to move out from the outside of the first clamping block 20, so as to release the fixation of the second fixture 14. Subsequently, the second bolt 26 is rotated to drive the second bolt 26 to move out from the inside of the mounting frame 2, so as to release the fixation of the stop block 25. Then, the first fixture 7 is pulled to the right to drive the first fixture 7 and the stop block 25 to move out from the inside of the groove 6, which facilitates the replacement of the first fixture 7 and the second fixture 14. Thus, it is convenient for the operator to replace the first fixture 7 and the second fixture 14 of different sizes, and it is convenient to install oxygen cylinders 30 of different sizes, which brings convenience to the operator's use.
