Description

Technical Field

[0001] This application relates to the field of gas cylinder technology, and in particular to gas cylinder mounting brackets. Background Technology

[0002] A gas cylinder is a refillable, portable pressure vessel used for storing and transporting compressed, liquefied, or dissolved gases. It is typically made of high-strength materials such as steel and aluminum alloys, and is usually cylindrical. In industrial production, it is used to store combustion-supporting or combustible gases such as oxygen and acetylene, supporting processes like welding and cutting. In the medical field, oxygen cylinders provide patients with the oxygen they need to breathe, ensuring their safety. In daily life, liquefied petroleum gas (LPG) cylinders are used for home cooking and heating. In scientific research, gas cylinders provide various special gases, a key element ensuring the smooth conduct of experiments, and offer safe and convenient solutions for gas storage and transportation in different scenarios.

[0003] Gas cylinders, through their high-strength container structure, seal and store gases in a compressed, liquefied, or dissolved state, maintaining stable gas storage by utilizing the internal and external pressure difference. In use, opening the valve allows the high-pressure gas inside to flow out of the cylinder under the pressure difference. After being regulated to a suitable pressure by a pressure-reducing device, the gas enters the equipment in use, realizing the release and supply of gas to meet the gas needs of various scenarios such as industrial production, medical treatment, and daily life. The flow of gas can be controlled by opening and closing the valve.

[0004] However, in existing technologies, some gas cylinders lack standardized securing devices, leading to haphazard placement that reduces work efficiency and safety. Due to the lack of standardized and adaptable securing equipment, users often have no choice but to place gas cylinders randomly on the ground or in corners. This not only results in a cluttered work area layout and requires extra time to find and move cylinders, significantly reducing work efficiency, but also poses serious safety hazards. Gas cylinders are prone to tipping over due to collisions or vibrations, causing valve damage, gas leaks, and potentially leading to fires, explosions, or poisoning accidents, posing a significant threat to personal safety and property. Furthermore, gas cylinders without securing devices are difficult to effectively secure and protect during transport, increasing instability and further exacerbating safety risks. Therefore, a gas cylinder securing rack is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a gas cylinder fixing rack, which aims to improve the problems of gas cylinders not having a unified fixing device, being placed randomly, reducing work efficiency, and having low safety during use.

[0006] The gas cylinder fixing frame provided in this application adopts the following technical solution: The gas cylinder fixing frame includes a load-bearing rod, a fixing mechanism is fixedly connected to both sides of the load-bearing rod, a clamping mechanism is fixedly connected to the front side of the fixing mechanism, a cylinder body is fixedly connected to the front side of the fixing mechanism, and valves are fixedly connected to the top of multiple cylinder bodies respectively; the fixing mechanism includes two support rods one, the bottom ends of the two support rods one on adjacent sides are fixedly connected to both sides of the load-bearing rod, two fixing rods are fixedly connected to the front side of the two support rods one, support rod two is fixedly connected to the adjacent side of the two fixing rods, connecting rod one is fixedly connected to the bottom ends of the two support rods one on adjacent sides, connecting rod three is fixedly connected to the bottom ends of the two support rods one on adjacent sides, connecting rod two is fixedly connected to the adjacent side of the two support rods one, and a limit component is fixedly connected to the front side of the connecting rod three;

[0007] The above technical solution utilizes a load-bearing rod as the basic support. The fixing mechanisms on both sides, through support rod one, fixed rod, support rod two, and connecting rods one, two, and three, construct a stable frame to support the bottle. The clamping mechanism on the fixing mechanism, in conjunction with the limiting components, ensures the bottle's stability. The valve is located at the top of the bottle, and the overall structure reliably fixes and supports the bottle.

[0008] Preferably, the clamping mechanism includes multiple connecting discs, the rear sides of the multiple connecting discs are fixedly connected to the front side of the connecting rod 2, the front sides of the multiple connecting discs are respectively fixedly connected to slide chambers, the inner walls of the multiple slide chambers are respectively slidably connected to two moving columns, the adjacent sides of the two moving columns are fixedly connected to a retractable column, the outer sides of the multiple retractable columns are all sleeved with springs, the front sides of the multiple moving columns are respectively fixedly connected to a fixing block, the front sides of the multiple fixing blocks are respectively fixedly connected to a clamping strip, and the adjacent sides of the two clamping strips are respectively fixedly connected to an anti-slip pad;

[0009] By adopting the above technical solution, the clamping mechanism is fixed to the connecting rod two with a connecting plate. The moving column in the slide can slide. The contraction column between the moving columns is fitted with a spring. When the bottle is put in, the bottle squeezes the clamping strip and drives the moving column to slide. The spring is compressed by force. The elastic restoring force of the spring is used to achieve stable clamping of the bottle.

[0010] Preferably, the limiting component includes a plurality of fixing posts 1, the rear side of the plurality of fixing posts 1 is fixedly connected to the front side of the connecting rod 3, the front side of the plurality of fixing posts 1 is respectively fixedly connected to a limiting ring 1, and the front side of the connecting rod 1 is fixedly connected to a plurality of fixing posts 2, the front side of the plurality of fixing posts 2 is respectively fixedly connected to a limiting ring 2.

[0011] By adopting the above technical solution, in the limiting assembly, fixing post one fixes limiting ring one to the front of connecting rod three, and fixing post two fixes limiting ring two to the front of connecting rod one. In use, limiting ring one and limiting ring two constrain the bottle from different directions, limiting the bottle's forward and backward movement and shaking.

[0012] Preferably, the outer surfaces of the plurality of limiting rings one are fixedly connected to the outer top surfaces of the plurality of bottles, and the inner walls of the plurality of limiting rings two are respectively fixedly connected to the inner bottom surfaces of the plurality of bottles;

[0013] By adopting the above technical solution, the first limiting ring is installed on the outside of the top of the bottle, and the second limiting ring is fixed on the inner wall of the bottom of the bottle. The two work together to provide double limiting from the top and bottom of the bottle.

[0014] Preferably, the two anti-slip pads are fixedly connected to the outside of the bottle body on adjacent sides, and the front sides of the plurality of slide chambers are fixedly connected to the rear sides of the plurality of bottles body;

[0015] By adopting the above technical solution, two anti-slip pads are tightly attached to the outside of the bottle body, increasing friction to prevent the bottle body from sliding; the slide is fixed to the rear side of the bottle body, and the elastic structure composed of the internal moving column, contracting column and spring firmly restrains the bottle body on the fixed frame.

[0016] Preferably, the front side of the plurality of slides is provided with a limiting groove, and the external side of the plurality of fixing blocks is slidably connected to the front inner wall of the plurality of slides;

[0017] By adopting the above technical solution, the limiting groove on the front side of the slide and the fixing block cooperate with each other. The fixing block can slide on the inner wall of the front side of the slide, and the limiting groove provides guidance and constraint for the sliding of the fixing block, ensuring that the fixing block drives the clamping strip to move smoothly on the predetermined trajectory.

[0018] Preferably, the rear outer sides of the plurality of clamping strips are slidably connected to the front inner walls of the plurality of slide chambers, and the rear outer sides of the plurality of anti-slip pads are slidably connected to the front inner walls of the plurality of slide chambers;

[0019] By adopting the above technical solution, the back of the clamping strip and the anti-slip pad are slidably connected to the inner wall of the front side of the slide chamber. When the bottle is fixed, the two can slide smoothly along the inner wall of the slide chamber and fit tightly against the outside of the bottle, so as to achieve tight clamping and stable protection of the bottle.

[0020] Preferably, the outer surfaces of the plurality of springs are slidably connected to the inner wall of the slide chamber, and the outer surfaces of the two springs are respectively fixedly connected to the adjacent sides of the two movable columns;

[0021] By adopting the above technical solution, the spring is sleeved on the inner wall of the slide chamber, and its two ends are fixed to the opposite sides of the two moving columns. When the clamping bar is squeezed by an external force, the moving column slides in the slide chamber to compress the spring, and the spring accumulates elastic potential energy. When the external force is removed, the spring pushes the moving column to reset by relying on the elastic restoring force, which drives the clamping bar to stably clamp the bottle. The elastic deformation of the spring is used to achieve adaptive clamping force adjustment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the load-bearing rod drives the fixing mechanisms on both sides to form an overall frame. The connecting rod one and connecting rod three in the fixing mechanism drive the limiting ring one and the limiting ring two respectively to position the bottle from the upper and lower ends, thereby achieving the effect of orderly arrangement and tight fixing of the bottle on the fixing frame, which saves space, facilitates management and retrieval, and improves the efficiency and safety of use.

[0024] 2. The connecting plate is fixed to the connecting rod two, which drives the slide chamber to be positioned. The spring and the contraction column on the inner wall of the slide chamber drive the moving column to slide in the limiting groove, thereby driving the fixing block and the clamping strip to move. At the same time, the limiting ring one and the limiting ring two, under the connection of the fixing columns one and two, respectively limit the top and bottom of the cylinder, thereby achieving a holistic and stable limiting and fixing effect for cylinders of different sizes from the side to the top and bottom, improving the adaptability and fixing reliability of the fixing frame for various gas cylinders.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0031] Example: Gas cylinder mounting bracket, see reference Figures 1 to 3 The system includes a load-bearing rod 1, with fixing mechanisms 2 fixedly connected to both sides of the load-bearing rod 1. The fixing mechanisms 2 are symmetrically installed on both sides of the load-bearing rod 1, and their main function is to securely connect components such as the clamping mechanism 3 and the bottle body 4 to the load-bearing rod 1. The clamping mechanism 3 is fixedly connected to the front of the fixing mechanism 2. When an object needs to be manipulated, the clamping mechanism 3 clamps or releases the object through its movement. Its connection with the fixing mechanism 2 ensures stable transmission of clamping force, guaranteeing the reliability and stability of the clamping process. The bottle body 4 is fixedly connected to the front of the fixing mechanism 2 and is used to store liquid or gas media. Valves 5 are fixedly connected to the top of multiple bottles 4. The valves 5 are installed at the top of the bottles 4 and are key components for controlling the release of the media inside the bottles 4. By opening or closing the valves 5, the outflow of the media inside the bottles 4 can be precisely controlled, achieving on-demand supply.

[0032] Specifically, the load-bearing rod 1 and the two fixing mechanisms 2 on both sides form a stable frame, providing an installation base for the bottle 4. The fixing mechanism 2 further drives the clamping mechanism 3, which firmly fixes the bottle 4 to the front of the frame through clamping action, thereby achieving stable constraint on the bottle 4.

[0033] The fixing mechanism 2 includes two support rods 21, which are symmetrically arranged. Their bottom ends are fixedly connected to both sides of the load-bearing rod 1, providing vertical support for the fixing mechanism 2. The bottom ends of the two support rods 21 on adjacent sides are fixedly connected to both sides of the load-bearing rod 1, effectively distributing the weight and external forces of the fixing mechanism 2 and its load-bearing components, enhancing the stability and anti-overturning ability of the entire device, and ensuring that the device remains stable under various working conditions. Two fixing rods 22 are fixedly connected to the front of each of the two support rods 21, providing an installation base for the second support rod 23. These rods also assist in fixing components such as the bottle body 4 and the clamping mechanism 3. The second support rod 23 is fixedly connected to the adjacent sides of the two fixing rods 22, connecting the two fixing rods 22, further enhancing the lateral stability of the fixing mechanism 2.

[0034] Specifically, the load-bearing rod 1 serves as the basic support, driving the support rods 21 on both sides to stand vertically, forming the basic column of the fixed mechanism 2; the support rod 21 then drives the fixed rod 22 to extend laterally, connecting with the support rod 23 to form a U-shaped three-dimensional frame structure.

[0035] Connecting rod 24 is fixedly connected to the bottom end of the two support rods 21 on their adjacent sides, connecting the two support rods 21 into a whole at the bottom, enhancing the torsional resistance of the fixing mechanism 2, preventing relative displacement of the support rods 21 under stress, and improving the overall stability and reliability of the fixing mechanism 2. Connecting rod 3 26 is fixedly connected to the bottom end of the two support rods 21 on their adjacent sides. Through cooperation with connecting rod 24, it forms a more stable bottom support network, effectively distributing the weight and external force from the upper components, ensuring that the fixing mechanism 2 remains stable even under complex working conditions. Connecting rod 25 is fixedly connected to the bottom end of the two support rods 21 on their adjacent sides, improving the overall rigidity of the fixing mechanism 2 and ensuring that the device will not deform when bearing heavy objects. Limiting component 27 is fixedly connected to the front side of connecting rod 3 26, which can prevent excessive movement of components or departure from normal working position, ensuring that each component operates within the specified area, and improving the safety and accuracy of the device's operation.

[0036] Specifically, the two support rods 1 21 drive the connecting rods 1 24, 3 26 and 25 to connect laterally, forming a stable support network at the bottom and middle, enhancing the overall stability of the fixing mechanism 2. The connecting rod 3 26 drives the limiting component 27 to extend forward, providing additional positioning constraints for the bottle body 4.

[0037] Reference Figures 2 to 4 The clamping mechanism 3 includes multiple connecting discs 31, which are fixedly connected to the second connecting rod 25 via their rear sides, thus securely mounting the clamping mechanism 3 onto the fixed mechanism 2. The rear sides of the multiple connecting discs 31 are fixedly connected to the front sides of the second connecting rod 25, enhancing the stability of the clamping mechanism 3 by utilizing the supporting role of the second connecting rod 25 within the fixed mechanism 2. Each of the multiple connecting discs 31 has a sliding chamber 32 fixedly connected to its front side. The sliding chamber 32 provides guidance and support for the moving column 33, ensuring that the moving column 33 slides stably along a straight line when subjected to force, achieving precise control of the clamping action. Two moving columns 33 are slidably connected to the inner walls of each of the multiple sliding chambers 32. When subjected to external force, the moving columns 33 can move towards or away from each other within the sliding chamber 32, driving the subsequent structure to clamp or release objects.

[0038] Specifically, connecting rod 25 drives connecting plate 31 to be positioned, providing a foundation for clamping mechanism 3. Connecting plate 31 then drives slide 32 to be fixed in place, allowing the moving column 33 on the inner wall of slide 32 to slide within a predetermined track, providing a movable component foundation for subsequent clamping of bottle 4.

[0039] Two movable columns 33 are fixedly connected to adjacent sides of each other with retractable columns 34. When the movable columns 33 move, the retractable columns 34 extend and retract accordingly, adjusting the distance between the two movable columns 33. Each of the retractable columns 34 is fitted with a spring 35. When the two movable columns 33 move towards each other under external force to clamp an object, the spring 35 is compressed and stores elastic potential energy. When the external force disappears, the spring 35 releases its elastic potential energy, pushing the movable columns 33 back to their original position, causing the clamping strip 37 to release the object. Fixed blocks 36 are fixedly connected to the front of each of the movable columns 33, connecting the movable columns 33 to the clamping strip 37 and transmitting force. Clamping strips 37 are fixedly connected to the front of each of the fixed blocks 36. When the movable columns 33 slide within the slide chamber 32, they cause the clamping strips 37 to move towards or away from each other, clamping or releasing the object. Anti-slip pads 38 are fixedly connected to the adjacent sides of the two clamping strips 37 respectively. The anti-slip pads 38 are in close contact with the surface of the object, which increases the friction to prevent the object from slipping. At the same time, their soft material can avoid scratching or damaging the surface of the object, thus improving the reliability and applicability of clamping.

[0040] Specifically, the two moving columns 33 drive the contraction column 34 and the spring 35 to work together. When subjected to external force, the spring 35 compresses and accumulates elastic potential energy. At the same time, the moving columns 33 drive the fixed block 36 and the clamping strip 37 to move, so that the anti-slip pad 38 fits the bottle body 4. After the external force disappears, the spring 35 rebounds and pushes the clamping strip 37 to clamp the bottle body 4.

[0041] Reference Figures 1 to 3 The limiting component 27 includes multiple fixing posts 271. The rear sides of the multiple fixing posts 271 are fixedly connected to the front sides of the connecting rod 26. The fixing posts 271 and the connecting rod 26 in the fixing mechanism 2 form a rigid connection, firmly integrating the limiting component 27 into the entire device structure. The front sides of the multiple fixing posts 271 are respectively fixedly connected to limiting rings 272. The limiting rings 272 are installed on the front sides of the fixing posts 271 and are used to limit the bottle 4 from above. The front sides of the connecting rod 24 are fixedly connected to multiple fixing posts 273. The fixing posts 273 correspond to the fixing posts 271 and are fixed on the front sides of the connecting rod 24 for installing limiting rings 274. The front sides of the multiple fixing posts 273 are respectively fixedly connected to limiting rings 274. The limiting rings 274 and the limiting rings 272 cooperate vertically to form a vertical constraint on the bottle 4, ensuring that the bottle 4 maintains a stable installation position in the fixing mechanism 2.

[0042] Specifically, connecting rod 3 26 drives fixing post 1 271 to extend forward, thereby positioning limiting ring 1 272 on the outside of the top of bottle body 4. Connecting rod 1 24 drives fixing post 273, thereby fixing limiting ring 274 to the inner wall of the bottom of bottle body 4, thus constraining and positioning it from both ends of bottle body 4.

[0043] Multiple limiting rings 272 are externally fixedly connected to the top of multiple bottles 4, rigidly securing the top of the bottles 4 and restricting their upward movement. During transport and operation, this effectively prevents the bottles 4 from slipping out of their fixed positions due to bumps or shaking. The inner walls of multiple limiting rings 274 are respectively fixedly connected to the bottom inner walls of multiple bottles 4. This provides a stable constraint on the bottles 4 from below, creating a clamping effect with the limiting rings 272. Two anti-slip pads 38 are fixedly connected to the outside of the bottles 4 on adjacent sides. The anti-slip pads 38, fixed to the outside of the bottles 4, utilize their high frictional properties to increase the friction between the clamping strip 37 and the bottles 4, preventing the bottles 4 from sliding during clamping.

[0044] Specifically, limiting ring 1 272 and limiting ring 274 are fixed from the outside of the top end and the inner wall of the bottom end of the bottle body 4 respectively, forming a limiting constraint in the vertical direction. The two anti-slip pads 38 are tightly attached to the outer side of the bottle body 4, providing friction from the side to prevent the bottle body 4 from sliding, and ensuring the stable fixation of the bottle body 4 in all directions.

[0045] Multiple slide chambers 32 are fixedly connected to the rear sides of multiple bottle bodies 4 at their front sides. The limiting grooves on the front sides of the slide chambers 32 are used to guide and limit components such as the fixing blocks 36 and clamping strips 37, ensuring that these components maintain linear motion during sliding. The limiting grooves on the front sides of the multiple slide chambers 32 are used to guide and limit components such as the fixing blocks 36 and clamping strips 37, ensuring that these components maintain linear motion during sliding. The external sliding connections of the multiple fixing blocks 36 are to the inner front walls of the multiple slide chambers 32. The fixing blocks 36 slide within the limiting grooves on the inner front walls of the slide chambers 32, accurately transmitting the movement of the moving column 33 to the clamping strips 37. Multiple clamping strips 37 are slidably connected to the front inner wall of multiple slide chambers 32 on their rear sides. The clamping strips 37 move towards or away from each other under the action of the fixing block 36 through the sliding cooperation between their rear sides and the front inner wall of the slide chamber 32, thereby completing the clamping or releasing action on the bottle body 4.

[0046] Specifically, the slide 32 provides an installation base and sliding track for the fixing block 36 and the clamping strip 37. The limiting groove on the front side of the slide 32 guides and constrains the fixing block 36, so that the fixing block 36 can drive the clamping strip 37 to slide smoothly along the inner wall of the front side of the slide 32, thereby achieving flexible clamping and release of the bottle 4.

[0047] Multiple anti-slip pads 38 are slidably connected to the rear outer side of multiple sliding chambers 32 on the front inner wall. This slidable connection between the rear side of the anti-slip pads 38 and the front inner wall of the sliding chambers 32 allows the anti-slip pads 38 to move synchronously with the clamping strips 37. Multiple springs 35 are slidably connected to the outer side of the sliding chambers 32. When the moving column 33 slides within the sliding chamber 32 under external force, the springs 35 can smoothly undergo elastic deformation along the inner wall, storing elastic potential energy when compressed. The two outer sides of the springs 35 are fixedly connected to adjacent sides of two moving columns 33. When the two moving columns 33 move towards each other under external force to achieve a clamping action, the springs 35 are compressed, storing elastic potential energy. When the external force disappears, the springs 35 release their elastic potential energy, pushing the two moving columns 33 to move in opposite directions, causing the clamping strips 37 to automatically reset and release.

[0048] Specifically, the inner wall of the slide 32 provides installation and sliding space for the spring 35 and the anti-slip pad 38. The two ends of the spring 35 are connected to the moving column 33. When the bottle body 4 squeezes the anti-slip pad 38, the rear side of the anti-slip pad 38 slides along the front inner wall of the slide 32, driving the moving column 33 to compress the spring 35. The spring 35 accumulates elastic potential energy and pushes the anti-slip pad 38 to fit tightly against the surface of the bottle body 4 by relying on the elastic force.

[0049] The implementation principle of this application embodiment is as follows: When it is necessary to place the gas cylinder, the load-bearing rod 1 forms a basic frame through the support rods 21 fixed on both sides. The fixed rod 22 on the front side of the support rod 21 and the support rod 23 form a horizontal support structure. The connecting rod 24, the connecting rod 25 and the connecting rod 26 connect the support rods 21 on both sides in the longitudinal direction to form a stable three-dimensional frame. The fixed column 271 on the front side of the connecting rod 26 drives the limiting ring 272 to limit and fix the top of the cylinder 4. The fixed column 273 on the front side of the connecting rod 24 drives the limiting ring 274 to support and fix the bottom inner wall of the cylinder 4. Through the synergistic effect of the upper and lower limiting components 27, multiple cylinders 4 are arranged in an orderly manner in the fixing mechanism 2, thereby achieving the effect of stable fixing and orderly arrangement of multiple cylinders 4, avoiding the cylinders 4 from shaking or tipping over, and improving the safety and standardization during storage and use.

[0050] When bottles of different sizes 4 are placed, the bottles 4 squeeze the anti-slip pad 38, causing the clamping strip 37 to move. The clamping strip 37 drives the moving column 33 to slide in the slide chamber 32 through the fixing block 36, causing the contraction column 34 to compress the spring 35. The elastic force generated by the spring 35 pushes the moving column 33, making the clamping strip 37 and the anti-slip pad 38 fit tightly against the bottle 4. At the same time, the limiting ring 1 272 and the limiting ring 274 limit and fix the bottle 4 from the top and bottom ends respectively, together achieving stable clamping of the bottle 4. This achieves precise adaptation and all-round fixation of bottles 4 of different diameters, improving the versatility and stability of the gas cylinder fixing rack.
