Description

Technical Field

[0001] This application relates to the field of pressure vessel fixing devices, and in particular to acetylene cylinder fixing brackets. Background Technology

[0002] Acetylene, a flammable and explosive gas, is widely used in industrial welding and cutting processes and is typically stored in high-pressure acetylene cylinders. Acetylene cylinders are classified as special equipment, and during transportation, storage, and use, they must be strictly protected from tipping, collisions, or violent vibrations. Failure to do so may result in cylinder damage, valve leaks, and ultimately, fires, explosions, and other safety accidents, posing a serious threat to life and property.

[0003] Currently, industrial supports for securing acetylene cylinders typically consist of a base and a frame structure. The base provides a supporting foundation, while the frame surrounds the base to create a protective space. A single-size clamp or strap is usually used to secure the acetylene cylinder, preventing significant movement within the support. These supports effectively secure the acetylene cylinders to a certain extent, meeting basic safety requirements.

[0004] Regarding the aforementioned technologies, the inventors believe that the existing acetylene cylinder fixing brackets are simple frame structures. When moving acetylene cylinders, it is necessary to manually lift the cylinders and then move them onto the fixing brackets for placement, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this application is to provide an acetylene cylinder fixing bracket to improve the existing acetylene cylinder fixing bracket, which is a simple frame structure. When moving acetylene cylinders, it is necessary to manually lift the acetylene cylinder and then move it to the fixing bracket for placement, which is time-consuming and labor-intensive.

[0006] The acetylene cylinder fixing bracket provided in this application adopts the following technical solution: An acetylene cylinder fixing bracket includes a base and a fixing frame extending around the base. A rotating plate is rotatably mounted on one side of the fixing frame. Limiting components are provided on both sides of the rotating plate. Each limiting component includes a limiting block connected to the side wall of the fixing frame. Limiting grooves corresponding to the limiting blocks are provided on both sides of the rotating plate. A stop component for limiting the position of the acetylene cylinder is provided on the side of the fixing frame near the rotating plate.

[0007] By adopting the above technical solution, the base and the fixed frame form a stable support foundation. The rotating plate provides a convenient opening and closing channel for loading and unloading acetylene cylinders, facilitating the loading and unloading operations. Personnel can move the acetylene cylinders onto the base by rotating the lowered rotating plate, solving the problem of the laborious task of lifting the entire acetylene cylinder during loading and unloading with traditional supports. The stop component provides effective restraint on the acetylene cylinders from the side, preventing significant displacement of the acetylene cylinders after they are placed on the base and fixed frame, thus improving the ease of operation and structural stability of the fixed support.

[0008] Optionally, the gear shift assembly includes a gear shift rod rotatably connected to the fixed frame. The end of the gear shift rod is provided with a locking groove. The fixed frame is provided with a positioning groove corresponding to the end of the gear shift rod. A fixing hook is rotatably provided on the inner sidewall of the positioning groove below the locking groove. The fixing hook rotates and contacts the locking groove.

[0009] By adopting the above technical solution, the stop lever is limited by rotating and engaging with the positioning groove of the fixed frame. This allows for quick switching of the constraint state on the acetylene cylinder in the fixed frame. The engagement groove and the fixed hook form a mechanical self-locking structure. The rotational contact of the fixed hook can reliably lock the end of the stop lever, thus fixing it in place. This ensures that the stop lever is limited after the acetylene cylinder is placed, guaranteeing reliable lateral fixation of the acetylene cylinder.

[0010] Optionally, the rotating plate is provided with a rotating rod that is rotatably connected to the fixed frame on the side near the base. The fixed frame is provided with a lifting groove corresponding to the rotating rod at the position of the rotating rod. The rotating plate is provided with a hand pull hole for easy lifting of the rotating plate.

[0011] By adopting the above technical solution, the movement of the rotating rod along the lifting groove brings the position of the limiting groove of the rotating plate to the same height as the limiting block. Then, the rotating plate moves down along the lifting groove, causing the limiting block to abut against the inner wall of the limiting groove of the rotating plate, thus fixing the vertical rotating plate. The pull hole provides a force point for adjusting the height of the rotating plate, making the adjustment operation more labor-saving and convenient, preventing jamming caused by the lack of a force point during the adjustment process, and improving the operating efficiency.

[0012] Optionally, the rotating plate is provided with a rubber pad on its side wall, and the top of the limiting block is provided with a second engaging groove corresponding to the inner side wall of the limiting groove. When the rotating rod moves along the lifting groove, the position of the limiting groove of the rotating plate is offset from the second engaging groove.

[0013] By adopting the above technical solution, when the rotating plate is lowered and the operator moves the acetylene cylinder to the base, the rubber pad increases the friction of the bottom of the acetylene cylinder moving along the side wall of the rotating plate, preventing the acetylene cylinder from slipping on the rotating plate during the movement and causing a safety accident. After the rotating plate is retracted, it is lifted along the lifting groove, so that the inner side wall of the limiting groove of the rotating plate falls into the second locking groove at the top of the limiting block. The inner side wall of the second locking groove engages with the limiting groove of the rotating plate, preventing the rotating plate from swaying left and right due to the vibration of the fixed frame and becoming loose. The staggered design of the limiting groove and the second locking groove when the rotating rod moves prevents interference between the two when adjusting the position of the rotating plate, ensuring that the adjustment of the rotating plate is smooth and unobstructed.

[0014] Optionally, the inner wall of the positioning groove is provided with an elastic element connected to the fixed hook, and the engaging groove is provided with a hanging rod corresponding to the fixed hook. The elastic element pushes the fixed hook to rotate and abut against the hanging rod. The fixed hook is provided with a pressing protrusion on the side facing the rotating plate.

[0015] By adopting the above technical solution, the hanging rod in the locking groove contacts the fixed hook, and the elastic element continuously pushes the fixed hook against the hanging rod to achieve automatic locking of the stop lever. The locked state can be maintained without additional operation, simplifying the operation process. At the same time, the side of the fixed hook away from the hanging rod is arc-shaped to prevent the fixed hook from interfering with or colliding with the inner wall of the locking groove when rotating, thus preventing the fixed hook from getting stuck. The pressing protrusion provides a convenient force structure for unlocking. Simply pressing can disengage the fixed hook from the hanging rod, achieving quick unlocking and balancing the reliability of locking with the convenience of operation.

[0016] Optionally, the base has a placement groove along its length, the inner sidewall of the placement groove corresponds to the arc portion of the bottom of the acetylene cylinder, and the fixing frame has a baffle along its width that contacts the sidewall of the acetylene cylinder, the sidewall of the baffle having an arc-shaped groove corresponding to the sidewall of the acetylene cylinder.

[0017] By adopting the above technical solution, the inner wall of the placement groove is adapted to the arc-shaped part of the bottom of the acetylene cylinder, which can accurately position the bottom of the cylinder and prevent the cylinder from shifting on the base. The baffle set on the fixed frame and the arc-shaped groove cooperate to fit the side wall of the cylinder from the side, increasing the contact area with the cylinder and further constraining the position of the acetylene cylinder. This avoids violent collisions between several acetylene cylinders placed on the base, which could cause cylinder deformation. It also enhances the lateral constraint on the cylinder, further prevents the cylinder from shaking, and improves the stability of the fixation.

[0018] Optionally, the baffle has two ends with bent plates corresponding to the fixed frame. The bent plates are rotatably equipped with limiting plates corresponding to the crossbars in the fixed frame. The side of the bent plates away from the limiting plates is rotatably equipped with a stop bar. The side of the limiting plates near the stop bar has a slot corresponding to the stop bar. The sidewall of the limiting plates is equipped with an anti-slip pad that presses against the crossbars of the fixed frame.

[0019] By adopting the above technical solution, the bending plate connects the baffle to the fixed frame, and the cooperation between the limiting plate and the crossbar of the fixed frame can quickly fix the position of the baffle to meet the lateral constraint requirements of the acetylene cylinder. The cooperation between the abutment and the slot can lock the limiting plate and prevent the bending plate from moving on the crossbar of the fixed frame, which would cause the baffle to loosen and the acetylene cylinder to shake. The anti-slip pad increases the friction by squeezing with the crossbar, further improving the fixing reliability of the limiting plate and making the lateral constraint of the baffle more stable. Overall, the fixing effect of the bracket on the acetylene cylinder is enhanced.

[0020] Optionally, a mounting frame corresponding to the acetylene cylinder is provided above the fixed frame. The mounting frame has several fixing slots corresponding to the acetylene cylinder along its length. The mounting frame is provided in several ways along the length of the fixed frame and is intersected with the baffle horizontally and vertically.

[0021] By adopting the above technical solution, the fixing groove of the mounting frame constrains the acetylene cylinder from the top, forming an "upper-middle-lower" three-dimensional fixing system with the placement groove at the bottom and the side baffles, which restricts the displacement of the cylinder in all directions. The horizontal and vertical crisscrossing layout of the mounting frame and the baffles makes the constraint forces in all directions work together to enhance the overall structure's anti-tipping ability.

[0022] Optionally, the mounting frame is provided with insert rods at both ends that connect to the fixed frame and the stop rod, and the top of the fixed frame and the top of the stop rod are provided with slots corresponding to the insert rods.

[0023] By adopting the above technical solution, the cooperation between the plug and the slot enables quick connection and disassembly of the mounting frame, the fixing frame, and the stop lever. Assembly can be completed without tools, which improves the assembly flexibility of the bracket. This detachable design allows the mounting frame to be added or removed flexibly according to usage needs, adapting to single or multiple bottle fixing scenarios. At the same time, it facilitates the storage and transportation of the bracket and reduces the storage space occupied.

[0024] Optionally, the fixing groove and the inner sidewall of the arc-shaped groove are provided with a buffer pad that contacts the sidewall of the acetylene cylinder.

[0025] By adopting the above technical solution, the buffer pads on the inner walls of the fixed groove and the arc-shaped groove absorb the vibration energy between the acetylene cylinder and the support through their own elasticity, reducing rigid collisions caused by bumps during transportation or use and avoiding damage to the cylinder surface; the buffer pads can also increase the friction with the cylinder, further preventing the cylinder from sliding within the constraint structure, taking into account both protection and fixing reliability, and improving the safety of using acetylene cylinders.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The base and fixed frame form a stable support foundation. The rotating plate provides a convenient opening and closing channel for loading and unloading acetylene cylinders. Operators can move the acetylene cylinders onto the base by rotating the lowered rotating plate, solving the problem of the laborious task of lifting the entire acetylene cylinder when loading and unloading with traditional brackets. The stop component provides effective restraint on the acetylene cylinder from the side, preventing the acetylene cylinder from shifting significantly after being placed on the base and fixed frame, thus improving the ease of operation and structural stability of the fixed bracket. 2. The bending plate connects the baffle to the fixed frame. The cooperation between the limiting plate and the crossbar of the fixed frame can quickly fix the position of the baffle, adapting to the lateral constraint requirements of gas cylinders of different diameters. The cooperation between the abutment and the slot can lock the limiting plate, preventing the bending plate from moving on the crossbar of the fixed frame, which would cause the baffle to loosen and the acetylene cylinder to shake. The anti-slip pad increases the friction by squeezing with the crossbar, further improving the fixing reliability of the limiting plate, making the lateral constraint of the baffle more stable, and enhancing the overall fixing effect of the bracket on the acetylene cylinder. 3. The mounting frame's fixing slots constrain the acetylene cylinder from the top, forming a three-dimensional "top-middle-bottom" fixing system with the bottom placement slots and side baffles. This system comprehensively restricts cylinder displacement. The staggered layout of the mounting frame and baffles ensures that the constraint forces in each direction work together. The combination of the insert rod and slot allows for quick connection and disassembly of the mounting frame, fixing frame, and stop rod, enabling tool-free assembly and improving the flexibility of the bracket assembly. This detachable design allows the mounting frame to be flexibly added or removed according to usage needs, adapting to single or multiple cylinder fixing scenarios. It also facilitates the storage and transportation of the bracket, reducing storage space requirements. Attached Figure Description

[0029] The following is combined with Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0030] Acetylene cylinder mounting bracket, refer to Figure 1 and Figure 2 The system includes a base 1 made of metal and a fixed frame 2. The fixed frame 2 is welded to the base 1 by multiple aluminum alloy horizontal and vertical bars. The fixed frame 2 extends vertically upward around the base 1 to form a rectangular frame structure. A rotating plate 3 made of metal is set on one side of the fixed frame 2. A rotating rod 32 is welded to the bottom of the rotating plate 3. A vertical lifting groove 23 is opened on the fixed frame 2 corresponding to the position of the rotating rod 32. The rotating rod 32 is embedded in the lifting groove 23 and can slide up and down along the groove wall. A hand pull hole 33 is opened on the rotating plate 3 for easy gripping. After the rotating plate 3 is rotated down, it provides a convenient opening and closing channel for loading and unloading the acetylene cylinder 5. The operator moves the acetylene cylinder 5 onto the base 1 by rotating the lowered rotating plate 3, which solves the problem of the laborious problem of having to lift the acetylene cylinder 5 as a whole when loading and unloading with traditional supports.

[0031] Reference Figure 1 and Figure 2The fixed frame 2 is provided with limit components 4 on both sides of the rotating plate 3. The limit components 4 include limit blocks 41 welded to the side walls of the fixed frame 2. Limit grooves 31 adapted to the limit blocks 41 are opened on both sides of the rotating plate 3. The top of the limit blocks 41 is provided with a second engagement groove 411. When the rotating plate 3 rotates upward and closes, the operator lifts the rotating plate 3 through the hand pull hole 33, so that the limit blocks 41 are located in the limit grooves 31 of the rotating plate 3. Then the rotating plate 3 is lowered, so that the inner side wall of the limit groove 31 and the inner side wall of the second engagement groove 411 of the limit block 41 intersect each other, and the rotation is reversed. The position of the movable plate 3 is fixed to prevent the rotating plate 3 from loosening due to vibration. When the rotating rod 32 moves, the limiting groove 31 and the locking groove 411 are designed to be staggered to prevent interference between the two when adjusting the position of the rotating plate 3, ensuring that the adjustment of the rotating plate 3 is smooth and unobstructed. A rubber pad 34 is attached to the side wall of the rotating plate 3 facing the acetylene cylinder 5. The rubber pad 34 also has an oblong hole corresponding to the hand pull hole 33. The rubber pad 34 increases the friction of the bottom of the acetylene cylinder 5 moving along the side wall of the rotating plate 3, preventing the acetylene cylinder 5 from slipping on the rotating plate 3 during the movement.

[0032] Reference Figure 2 and Figure 3 A stop assembly 6 is provided on the side of the fixed frame 2 near the rotating plate 3. The stop assembly 6 includes a stop rod 61 rotatably connected to the fixed frame 2. The stop rod 61 is hinged to the fixed frame 2 at the same end as the rotating plate 3. A locking groove 62 is provided at the end of the stop rod 61. A hanging rod 621 is welded into the locking groove 62. A positioning groove 21 is provided on the fixed frame 2 at the position corresponding to the end of the stop rod 61. A fixed hook 22 is rotatably connected to the inner wall of the positioning groove 21 below the locking groove 62 via a pin. An elastic element 211 is connected between the fixed hook 22 and the inner wall of the positioning groove 21. The elastic element 211 is a torsion spring that abuts against the side wall of the fixed hook 22. 1. In its natural state, the fixed hook 22 is pushed against the hanging rod 621 to automatically lock the stop lever 61. The locked state can be maintained without additional operation, simplifying the operation process. The fixed hook 22 has a pressing protrusion 221 integrally formed with the fixed hook 22 on the side facing the rotating plate 3. Simply pressing the pressing protrusion 221 will cause the fixed hook 22 to rotate and disengage from the hanging rod 621, achieving quick unlocking and balancing the reliability of locking and the convenience of operation. The fixed hook 22 is arc-shaped on the side away from the hanging rod 621 to prevent the fixed hook 22 from interfering with or colliding with the inner wall of the locking groove 62 when rotating, which would cause the fixed hook 22 to jam and prevent the stop lever 61 from rotating.

[0033] Reference Figure 1 and Figure 2Multiple placement slots 11 are spaced apart along the length of the upper surface of the base 1. The inner sidewall of the placement slot 11 is adapted to the arc-shaped part of the bottom of the acetylene cylinder 5, which can accurately position the bottom of the cylinder and prevent the cylinder from shifting on the base 1. A baffle 7 is provided along the width of the fixing frame 2. The sidewall of the baffle 7 has an arc-shaped groove 71 corresponding to the sidewall of the acetylene cylinder 5. The arc-shaped groove 71 corresponds vertically to the placement slot 11 and fits against the sidewall of the acetylene cylinder 5 from the side, increasing the contact area with the cylinder and further constraining the position of the acetylene cylinder 5. This prevents violent collisions between several acetylene cylinders 5 placed on the base 1, which could cause cylinder deformation. It also enhances the lateral constraint on the cylinder, further prevents the cylinder from shaking, and improves the stability of the fixing. Bending plates 72 are welded to both ends of the baffle 7. The bent part of the bending plate 72 is connected to the fixing frame 2. The crossbars of frame 2 are engaged, and a limiting plate 73 is rotatably connected to the bent plate 72 via a pivot. The engagement of the limiting plate 73 with the crossbar of the fixed frame 2 can quickly fix the position of the baffle 7. A stop rod 74 is rotatably connected to the side of the bent plate 72 away from the limiting plate 73 via a pin. A slot 731 adapted to the stop rod 74 is provided on the side of the limiting plate 73 near the stop rod 74. After the stop rod 74 is rotated, it can be inserted into the slot 731 to prevent the bent plate 72 from moving on the crossbar of the fixed frame 2, which would cause the baffle 7 to loosen and the acetylene cylinder 5 to shake. An anti-slip pad 732 is attached to the side wall of the limiting plate 73. The anti-slip pad 732 is made of PVC material. When the limiting plate 73 is fixed, the anti-slip pad 732 and the crossbar of the fixed frame 2 squeeze each other to increase the friction, further improving the fixing reliability of the limiting plate 73 and making the lateral constraint of the baffle 7 more stable.

[0034] Reference Figure 1 and Figure 3 An installation frame 24 is provided above the fixed frame 2. Multiple fixing slots 241, corresponding to the side walls of the acetylene cylinder 5, are provided along the length of the installation frame 24. The fixing slots 241 are adapted to the side walls of the acetylene cylinder 5. Multiple installation frames 24 are provided along the length of the fixed frame 2 and are distributed horizontally and vertically intersecting with the baffle 7, forming an "upper-middle-lower" three-dimensional fixing system with the bottom placement slot 11 and the side baffle 7, comprehensively restricting cylinder displacement. Insert rods 242 are welded to both ends of the installation frame 24, as well as to the top of the fixed frame 2 and the top of the baffle rod 61. A slot 25 is provided to fit the insertion rod 242. The insertion rod 242 is inserted into the slot 25 to fix the mounting frame 24, and at the same time facilitates the quick connection and disassembly of the mounting frame 24. The inner sidewalls of the fixing groove 241 and the arc groove 71 are both covered with a buffer pad 711. The buffer pad 711 is made of polyurethane material, which absorbs the vibration energy between the acetylene cylinder 5 and the bracket, reduces rigid collisions caused by bumps during transportation or use, and avoids damage to the cylinder surface. The buffer pad 711 can also increase the friction with the acetylene cylinder 5, further preventing the cylinder from sliding within the constraint structure.

[0035] The implementation principle of this application embodiment is as follows: During loading and unloading, the operator pulls the rotating plate 3 through the hand-operated hole 33 to lift it, causing the limiting groove 31 of the rotating plate 3 to move away from the engaging groove 411 of the limiting block 41 until they are completely disengaged. Then, the rotating plate 3 is rotated down, forming a relatively gentle slope with the base 1, providing a wide insertion channel for the acetylene cylinder 5. The operator then moves the acetylene cylinder 5 onto the base 1 using the rigid rotating plate 3, allowing it to move along the placement groove 11. The placement groove 11 at the bottom matches the arc of the cylinder bottom, achieving initial positioning of the cylinder. Positioning: After placing a row of acetylene cylinders 5 along the width of the base 1, insert a baffle 7 through the gap in the fixing frame 2. The lateral baffle 7 fits against the side wall of the cylinder through the arc groove 71, providing a constraint on the movement of the acetylene cylinders 5. The limiting plate 73 on the bent plate 72 cooperates with the crossbar of the fixing frame 2 to fix the position of the baffle 7. The abutment 74 is embedded in the slot 731 to lock the limiting plate 73. The anti-slip pad 732 enhances friction to prevent loosening, forming a stable constraint from the side. Then, continue to place the acetylene cylinders 5 and install the baffle 7. After the acetylene cylinder 5 is placed, the rotating plate 3 is rotated and lifted to close, so that the limiting block 41 is located in the limiting groove 31 of the rotating plate 3. Then, the rotating plate 3 is lowered along the lifting groove 23, so that the inner wall of the limiting groove 31 and the inner wall of the engagement groove 411 of the limiting block 41 intersect each other, thus fixing the position of the rotating plate 3 and preventing the rotating plate 3 from loosening due to vibration. The stop rod 61 is rotated to the fixing groove 241 of the fixing frame 2, and the fixing hook 22 in the positioning groove 21 engages with the elastic element 211. The stop lever 61 is locked by engaging the automatic locking groove 62 with the hanging rod 621. To unlock, press the protrusion 221 to disengage the fixing hook 22 from the hanging rod 621, and then rotate the stop lever 61 to release the bottle. The operation is convenient and the locking is reliable. The top mounting frame 24 constrains the bottle from above through the fixing groove 241. The cooperation between the insertion rod 242 and the slot 25 allows the mounting frame 24 to be flexibly installed and removed. The horizontal and vertical layout of the baffle 7 forms a three-dimensional fixing system, which restricts the displacement of the bottle in three dimensions in all directions. After the rotating plate 3 is rotated down, it provides a convenient opening and closing channel for loading and unloading the acetylene cylinder 5. The operator can move the acetylene cylinder 5 onto the base 1 by rotating the lowered rotating plate 3, which solves the problem of the laborious problem of having to lift the acetylene cylinder 5 as a whole when loading and unloading with traditional brackets.
