Description

Technical Field

[0001] This utility model relates to the field of special equipment manufacturing and safety protection, and in particular to a carbon fiber oxygen cylinder with good protective properties. Background Technology

[0002] Traditional metal oxygen cylinders suffer from drawbacks such as heavy weight, susceptibility to corrosion and rust, and poor protective performance. Steel oxygen cylinders are heavy and inconvenient to carry, and the metal is susceptible to environmental corrosion, affecting their lifespan and oxygen purity; their coatings offer limited protection. In contrast, carbon fiber materials are high-strength, lightweight, with a density only about 40% that of steel, resistant to chemical corrosion and UV radiation, and possess excellent impact resistance. With the maturation of composite material technology, the demand for high-performance oxygen cylinders has surged in medical, firefighting, and aerospace fields, leading to the development of carbon fiber oxygen cylinders.

[0003] Carbon fiber oxygen cylinders store oxygen thanks to their high strength and airtightness. The cylinder body, manufactured using a winding process, is highly pressure-resistant. Oxygen is then filled into the cylinder at high pressure using a compression device. When in use, the cylinder valve is opened, and the high-pressure oxygen flows out along the pipeline due to the pressure difference. The pressure is then adjusted to a suitable pressure by a pressure reducing device for the user's breathing or other purposes. The entire process ensures safe storage and stable release of oxygen through cylinder pressure resistance and valve regulation.

[0004] Currently, carbon fiber oxygen cylinders are injecting vitality into the industry with their lightweight and high-strength characteristics, significantly improving the efficiency of use in scenarios such as medical emergency and fire rescue. However, due to differences in pipeline interface standards in scenarios such as medical terminals, industrial equipment, and aviation oxygen supply, it is difficult to unify the specifications of oxygen cylinder nozzles. When frequently changing oxygen cylinders with different interfaces, it is necessary to repeatedly disassemble, adjust the pipeline, and check the sealing performance. The operation process is lengthy, which not only delays the emergency rescue opportunity but also increases the risk of human error. The interface compatibility problem has become a bottleneck restricting its efficient application. There is an urgent need for the industry to establish a universal interface standard or develop a rapid adaptation and conversion device to shorten the oxygen supply preparation cycle and unleash the full-scenario application potential of carbon fiber cylinders. To this end, a carbon fiber oxygen cylinder with good protection is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a carbon fiber oxygen cylinder with good protection, aiming to improve the efficiency of existing carbon fiber oxygen cylinders in multiple scenarios, but the lack of standardized interfaces restricts their efficient application.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective carbon fiber oxygen cylinder includes a cylinder body, an outlet pipe fixedly connected to the top of the cylinder body, a support plate fixedly connected to the outer wall of the outlet pipe, a circular shell fixedly connected to the top of the support plate, a rotating disk rotatably connected inside the circular shell, a plurality of grooves formed inside the rotating disk, sliders slidably connected inside each of the grooves, a plurality of limiting blocks fixedly connected inside the circular shell, through holes formed inside the limiting blocks, a control valve slidably connected to the outer wall of the outlet pipe, and a protective component provided at the bottom of the cylinder body.

[0008] As a further description of the above technical solution:

[0009] The protective assembly includes a base plate, the top of which contacts the bottom of the bottle. Outer plates are fixedly connected to both sides of the top of the base plate. Two outer shells are rotatably connected to one side of the outer shells. A connecting plate is fixedly connected to one side of the outer shells. Limiting posts are slidably connected to the four corners of the other side of the connecting plate. Protective plates are fixedly connected to the four limiting posts on the side away from the connecting plate. Springs are sleeved on the outer walls of the four limiting posts.

[0010] As a further description of the above technical solution:

[0011] A push block is fixedly connected to the outer wall of the rotating disk, and the outer wall of the push block is slidably connected to the inner wall of the circular shell.

[0012] As a further description of the above technical solution:

[0013] The push block is slidably connected to a fixed column on the side away from the rotating disk, and the outer wall of the fixed column is slidably connected to the inside of the support disk;

[0014] As a further description of the above technical solution:

[0015] The bottom of the push block is in contact with the top of the support plate, and the top of the slider is provided with a protrusion;

[0016] As a further description of the above technical solution:

[0017] One side of the spring is in contact with one side of the protective plate, and the other side of the spring is in contact with one side of the connecting plate;

[0018] As a further description of the above technical solution:

[0019] The outer walls of the plurality of protrusions are slidably connected to the inner walls of the plurality of through holes, and the bottoms of the plurality of limiting blocks and the tops of the plurality of sliders are in contact.

[0020] As a further description of the above technical solution:

[0021] The two outer shells are bolted to one side of another outer plate, and one side of the outer shell is in contact with the outer wall of the bottle.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by inserting the external interface pipe into the inside of the round shell and pushing the push block to apply force, the slider slides precisely along the through hole path in the groove. Multiple sliders are circumferentially distributed, and their adjacent sides form an adjustable hollow range. As the slider slides, the hollow range can be reduced or expanded as needed. By fine-tuning to the appropriate size, the external interface pipe can be tightly fitted to the outer wall of the gas outlet pipe. This structure uses a slider linkage adjustment mechanism to achieve tight connection at the interface, ensuring the sealing and stability during gas transmission, thereby enabling the external interface pipes of different specifications to be adjusted and used.

[0024] 2. In this utility model, the outer shell and the outer plate are firmly fixed by bolts to form a basic protective frame. When an external force impacts the protective plate, the protective plate is pushed by the force to move the limiting post towards the connecting plate. During this process, the built-in spring is compressed. The spring undergoes elastic deformation due to the external force and accumulates energy. Then it quickly rebounds and releases the buffer force. This mechanism effectively offsets the impact of the external force on the protective plate through the deformation and rebound of the spring, converting the energy into the elastic potential energy of the spring, thereby reducing the direct effect of the external force on the internal structure and providing reliable buffer protection for the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a carbon fiber oxygen cylinder with good protection, comprising a cylinder body 1, which serves to store oxygen. An outlet pipe 2 is fixedly connected to the top of the cylinder body 1, serving to input and output oxygen. A support plate 4 is fixedly connected to the outer wall of the outlet pipe 2, and a circular shell 5 is fixedly connected to the top of the support plate 4, serving a protective function. A rotating disk 6 is rotatably connected inside the circular shell 5, serving an important adjustment function. Multiple grooves 7 are formed inside the rotating disk 6, and sliders 8 are slidably connected inside each groove 7, allowing the sliders 8 to move along a specific path. Multiple limiting blocks 9 are fixedly connected inside the circular shell 5, and through holes 10 are formed inside each limiting block 9. A control valve 3 is slidably connected to the outer wall of the outlet pipe 2, controlling whether oxygen can enter or be released from the cylinder body 1. A protective component is provided at the bottom of the cylinder body 1.

[0033] Reference Figure 2 and Figure 3 The protective assembly includes a base plate 13, which supports the entire device. The top of the base plate 13 contacts the bottom of the bottle 1, allowing the bottle 1 to be removed and placed. Outer plates 14 are fixedly connected to both sides of the top of the base plate 13, and the outer plates 14 serve a protective function. Two outer shells 15 are rotatably connected to one side of the outer plate 14, allowing the two outer shells 15 to rotate on one side of the outer plate 14. A connecting plate 16 is fixedly connected to one side of the outer shell 15. Limiting posts 17 are slidably connected to the four corners of the other side of the connecting plate 16, making the force more even. Protective plates 19 are fixedly connected to the side of the four limiting posts 17 away from the connecting plate 16. Springs 18 are sleeved on the outer walls of the four limiting posts 17, so that the springs 18 can have elasticity when compressed.

[0034] Reference Figures 2 to 4A push block 11 is fixedly connected to the outer wall of the rotating disk 6, allowing the rotating disk 6 to be rotated and adjusted. The outer wall of the push block 11 is slidably connected to the inner wall of the circular shell 5. A fixing post 12 is slidably connected to the side of the push block 11 away from the rotating disk 6. The outer wall of the fixing post 12 is slidably connected to the inside of the support disk 4. Due to the presence of the fixing post 12, when the push block 11 is pushed to adjust the rotating disk 6 to a suitable position, the fixing post 12 is pressed down, thus fixing the push block 11 and the support disk 4. The bottom of the push block 11 is in contact with the top of the support disk 4, and the push block 11 slides on the top of the support disk 4. A protrusion is provided on the top of the slider 8, and the spring 18... One side of the spring 18 contacts the side of the protective plate 19, and the other side of the spring 18 contacts the side of the connecting plate 16, so that the spring 18 can be compressed. The outer walls of multiple protrusions are slidably connected to the inner walls of multiple through holes 10, so that when the slider 8 slides along the path of the groove 7, it moves along the path of the through hole 10 at the same time. The bottom of multiple limiting blocks 9 contacts the top of multiple sliders 8, and the top of the slider 8 slides on the bottom of the limiting blocks 9. The two outer shells 15 are fixedly connected to the side of another outer plate 14 by bolts 20, making the whole device more stable. One side of the outer shell 15 contacts the outer wall of the bottle 1, so that the bottle 1 can be placed or removed.

[0035] Working principle: When oxygen is needed from the oxygen cylinder, the pipe of the external interface is inserted into the round shell 5. The pusher 11 is pushed so that the slider 8 slides along the path of the through hole 10 in the groove 7. This causes the gap between adjacent sides of multiple sliders 8 to shrink or expand, adjusting to a suitable size so that the pipe of the external interface is tightly fitted to the outer wall of the outlet pipe 2. When the cylinder 1 needs to be stored and fixed, the outer shell 15 and the outer plate 14 are fixed with bolts 20. When an external force touches the protective plate 19, the protective plate 19 pushes the limiting post 17 to move towards the connecting plate 16. Due to the presence of the spring 18, the spring 18 is compressed and deformed and rebounds, thus offsetting part of the force on the protective plate 19, thereby achieving the purpose of protecting the cylinder 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
