Description

Technical Field

[0001] This utility model relates to the field of diving equipment technology, specifically to a buoyancy bag cylinder belt device structure. Background Technology

[0002] A buoyancy bag is an inflatable structure used in marine environments to lift or support heavy objects (such as diving cylinders). It generates buoyancy through its internal inflatable chambers to counteract the weight of the object, achieving suspension or buoyancy. In diving operations, buoyancy bags are often used in conjunction with buoyancy vests (BCDs) or individual cylinder bags to help divers maintain a stable posture and facilitate carrying the cylinders.

[0003] Existing buoyancy bag cylinder strapping devices typically use a combination of nylon flat straps and metal fasteners for attachment. Without a back frame, a single cylinder can be secured to a buoyancy vest or backplate by wrapping the main strap around it and reinforcing it with auxiliary straps. To meet different depth and operational needs, divers often need to precisely control the cylinder's depth and hovering position by adjusting the buoyancy bag volume or adding weights. However, existing devices lack a cushioning structure in their design, failing to effectively mitigate the impact of underwater obstacles (such as reefs) on the cylinder, easily leading to damage to the cylinder casing and affecting operational safety. Furthermore, cylinders can become entangled in seaweed during underwater operations. In emergencies, divers need to quickly remove the cylinder; traditional buoyancy bag cylinder strapping devices can only open from one side to remove the cylinder, hindering rapid disassembly and affecting the timely escape of the buoyancy bag from distress.

[0004] Therefore, there is an urgent need to design a buoyancy bag cylinder belt device structure to meet the safety and reliability requirements of modern diving equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a buoyancy bag cylinder belt device structure, which enables rapid assembly and disassembly of the cylinder in both the upper and lower directions, thereby improving underwater rescue response capabilities.

[0006] The technical solution adopted by this utility model to solve the above problems is: a buoyancy bag gas cylinder belt device structure, including a bottle belt body fixed to the outside of the buoyancy bag, the bottle belt body including a bag body for storing gas cylinders, a leak-proof cover detachably connected to the top of the bag body, the leak-proof cover having an opening for the gas cylinder nozzle to be exposed, and a bottom cover provided at the bottom of the bag body, the bottom cover adopting an openable structure design.

[0007] Preferably, the leak-proof cover is detachably connected and fixed to the bag body by a first fastener.

[0008] Preferably, the bag body is detachably connected to a frame sleeve that matches the outer surface of the gas cylinder, and a hook portion that matches the upper edge of the bag body is provided on the top of the frame sleeve.

[0009] Preferably, the inner side of the frame is provided with a side pad that contacts the gas cylinder.

[0010] Preferably, the bag body has side fixing straps on the left and right sides that are connected and fixed to the outer surface of the buoyancy bag, and a bottom fixing strap at the bottom of the bag body that is connected and fixed to the outer surface of the buoyancy bag.

[0011] Preferably, the bottom cover is connected and fixed to the bottom of the bag body by a double-headed zipper structure, and the bottom fixing strap is located below the bottom cover.

[0012] Preferably, the bottom cover is detachably connected to a bottom pad via a second fastener.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention features a detachable top and bottom structure, allowing the gas cylinder to be removed from the top of the bag or quickly released from the bottom cover, improving the flexibility of cylinder installation and replacement and significantly enhancing emergency response capabilities in underwater operations. The leak-proof cover and bottom cover effectively prevent the cylinder from detaching and improve sealing performance, preventing foreign objects from entering. The frame structure provides rigid external protection for the cylinder, while flexible side pads cushion impacts, reducing the risk of damage during collisions and improving the overall safety and reliability of the diving equipment. Side and bottom securing straps firmly fix the cylinder to the outside of the buoyancy bag, preventing its movement from adversely affecting the diver. The bottom pad further enhances the impact resistance of the cylinder bottom. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example:

[0022] See Figures 1-4 In this embodiment, a buoyancy bag 11 cylinder carrying device structure is involved, which is specifically used for fixing, protecting and quickly disassembling diving cylinders in diving operations, improving the safety and ease of operation for divers. Specifically, it includes a cylinder carrying body 12 fixed to the outside of the buoyancy bag 11. The cylinder carrying body 12 includes a bag body 13 for storing the cylinder. A leak-proof cover 14 is detachably connected to the top of the bag body 13. The leak-proof cover 14 has an opening 15 for exposing the cylinder nozzle. A bottom cover 16 is provided below the bag body 13. The bottom cover 16 adopts an openable structure design.

[0023] Specifically, in this embodiment, when installing the gas cylinder, the leak-proof cover 14 must first be opened to expose the upper opening of the bag body 13, allowing the gas cylinder to be inserted into the bag body 13. The gas cylinder's nozzle should extend from the opening 15 of the leak-proof cover 14. Then, the leak-proof cover 14 is connected and fixed to the bag body 13 to complete the gas cylinder installation. The leak-proof cover 14 effectively secures the gas cylinder within the bag body 13, preventing leakage. A bottom cover 16 is provided at the bottom of the bag body 13, allowing the gas cylinder to be inserted from below. The bag body 13 of the cylinder strap body 12 can be opened from both the top and bottom, facilitating the removal and replacement of the gas cylinder. Furthermore, the bag body 13 features a structure that can be opened from both ends, increasing safety redundancy. This allows divers to easily remove the gas cylinder from the buoyancy bag 11 in crisis situations (such as a broken gas cylinder or entanglement with seaweed), effectively improving safety and emergency response capabilities during diving operations.

[0024] The leak-proof cover 14 is detachably connected and fixed to the bag body 13 by the first fastener 21. The first fastener 21 is a commonly used elastic plastic buckle, which includes a male buckle 22 and a female buckle 23 that are elastically locked together. The first fastener 21 is used to connect the leak-proof cover 14 to the bag body 13, close the top of the bag body 13, and prevent the gas cylinder from falling out.

[0025] The bag body 13 is detachably connected to a frame sleeve 24 that fits the outer surface of the gas cylinder. In this embodiment, the bag body 13 is made of flexible, wear-resistant, and waterproof fabric, while the frame sleeve 24 can be made of high-strength engineering plastic or composite material. The frame sleeve 24 surrounds the outer surface of the gas cylinder and fits snugly against it. When the cylinder body 12 is impacted by an external force, the plastic frame sleeve 24 first bears the impact load, dispersing the impact force to the entire surface of the frame sleeve 24 through its own rigid structure, thus preventing concentrated force on the surface of the gas cylinder and causing damage. Furthermore, since the gas cylinder needs to be replaced when the internal pressure is insufficient, while the frame sleeve 24 can be used indefinitely without damage, the gas cylinder needs to be replaced more frequently than the frame sleeve 24. In this embodiment, the bag body 13 is opened before inserting the frame sleeve 24, and then the gas cylinder is inserted, eliminating the need to open the bag body 13 during gas cylinder installation, making gas cylinder replacement relatively convenient.

[0026] In this embodiment, a hook 25 adapted to the upper edge of the bag body 13 is provided on the upper part of the frame sleeve 24. After the frame sleeve 24 is wrapped around the surface of the gas cylinder and in place, the hook 25 on its upper edge can engage with the corresponding buttonhole 26 provided on the upper edge of the bag body 13. Specifically, the upper edge of the bag body 13 is provided with a number of equally spaced buttonholes 26 along the circumference. Each buttonhole 26 is reinforced by reinforcing stitching and tear-resistant fabric pads. The hook 25 on the upper part of the frame sleeve 24 is a metal hook with rounded chamfered edges. By inserting the hook 25 into the buttonhole 26, the frame sleeve 24 can be installed and fixed, and a stable connection between the frame sleeve 24 and the bag body 13 can be achieved.

[0027] The inner side of the frame sleeve 24 is provided with a side gasket 27 that contacts the gas cylinder. The side gasket 27 can be made of soft materials such as neoprene rubber. On the one hand, by filling the gap between the gas cylinder and the frame sleeve 24, the side gasket 27 restricts the rotation of the gas cylinder relative to the frame sleeve 24, thereby improving the installation stability of the gas cylinder; on the other hand, the side gasket 27 can also absorb the impact energy transmitted from the frame sleeve 24 to the gas cylinder, thereby improving the overall protection effect.

[0028] The bag body 13 has side fixing straps 31 on its left and right sides that are connected and fixed to the outer surface of the buoyancy bag 11, and a bottom fixing strap 32 on the bottom of the bag body 13 that is connected and fixed to the outer surface of the buoyancy bag 11. The side fixing straps 31 are arranged along the outer periphery of the bag body 13, forming a clamping ring around the gas cylinder. The tension of the side fixing straps 31 can be adjusted by fasteners (such as D-rings), which can lock the position of the bag body 13 in the left and right directions, effectively limiting the swaying of the gas cylinder and reducing the interference of the gas cylinder swaying with the diver's balance during diving.

[0029] In this embodiment, the bottom cover 16 is connected and fixed to the bottom of the bag body 13 via a double-ended zipper 33 structure (with a waterproof and sealed design). The double-ended zipper 33 is located at the bottom edge of the bag body 13, forming an openable annular opening 15 to allow the bottom cover 16 to be opened and closed. In an emergency, the gas cylinder can be quickly removed from under the bag body 13 by sliding the zipper 33 with one hand.

[0030] The bottom cover 16 is detachably connected to a bottom pad 35 via a second fastener 34. In this embodiment, the bottom pad 35 can be an air cushion for cushioning and protecting the bottom of the gas cylinder. The second fastener 34 is a commonly used snap fastener, which includes a pin 36 on the bottom cover 16 and a slot 37 below the air cushion. The pin 36 and the slot 37 are interference-fitted, and the air cushion can be easily removed and replaced after the bottom cover 16 is opened via the zipper 33.

[0031] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
