Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting torches, and specifically relates to a copper pipe dedicated to a cutting torch. Background Technique
[0002] A cutting torch is the main tool for gas cutting. Its main function is to mix combustible gas and oxygen in the cutting torch to form a preheating flame with a certain heat energy and shape, and in the center of the preheating flame, a high-pressure oxygen stream is ejected to carry out gas cutting work. The structure of the cutting torch is that the cutting torch conduit is connected to a gas fuel source;
[0003] Among them, the cutting torch conduits are all made of special copper pipes. Because copper is not easy to oxidize, in a high-temperature, oxidizing gas and welding environment, it will not oxidize itself, and the made torch does not rust and does not block the pipeline; and copper can withstand a certain high temperature. Although a temperature of 3000 °C is sufficient to melt the torch nozzle, but at the same time as the high temperature is generated, it is pushed out and cooled by the subsequent mixed gas, so it will not melt the copper that can withstand a certain high temperature; copper is relatively soft and easy to process, and the manufactured seals are easy to self-seal.
[0004] However, due to the excessively long gas mixing pipeline of the copper pipe dedicated to the cutting torch, the excessively long gas pipeline may be broken when it is impacted during placement, or after a long period of high-pressure gas output work, the reliability of the overall pipeline structure is poor; therefore, it does not meet the existing requirements, and for this reason, we propose a copper pipe dedicated to a cutting torch.

Detailed Embodiment
[0024] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.
[0025] Please refer to Figures 1 to 4, An embodiment provided by the present utility model: A copper pipe dedicated to a cutting torch, including a handle 1. The upper and lower ends of one end of the handle 1 are respectively installed with a high-pressure oxygen pipe 2 and an acetylene pipe 3. The ends of the high-pressure oxygen pipe 2 and the acetylene pipe 3 away from the handle 1 are connected to a cutting nozzle 4. On both sides of the upper end of the outer surface of the high-pressure oxygen pipe 2, there are respectively a first upper support block 5 and a second upper support block 6. On both sides of the lower end of the outer surface of the acetylene pipe 3, there are respectively a first lower support block 7 and a second lower support block 8 corresponding to the first upper support block 5 and the second upper support block 6. Between the first upper support block 5 and the second upper support block 6, and between the first lower support block 7 and the second lower support block 8, they are all connected by a threaded rod 12; between the first upper support block 5 and the first lower support block 7, and between the second upper support block 6 and the second lower support block 8, there are adjustment mechanisms for adjusting the distances between the first upper support block 5 and the first lower support block 7, and between the second upper support block 6 and the second lower support block 8.
[0026] When this application is in use, according to the actual operation requirements, the distance between the two upper support blocks can be adjusted through the threaded rod 12. Then, the distance between the first lower support block and the second lower support block is adjusted in the same way, and the upper and lower support blocks on both sides are made to correspond. Thus, the position between the support blocks can be adjusted according to the lengths of the high-pressure oxygen pipe and the acetylene pipe. By supporting and fixing the high-pressure oxygen pipe and the acetylene pipe, the problem that the copper pipe dedicated to the cutting torch may break due to the overly long gas mixing pipeline is solved. The adjustment mechanism is used to adjust the distances between the first upper support block 5 and the first lower support block 7, and between the second upper support block 6 and the second lower support block 8. It can play a certain role in strengthening and protecting the high-pressure oxygen pipe and the acetylene pipe.
[0027] After the adjustment is completed, the gas supply system is turned on, and oxygen and acetylene gases are mixed in a set ratio and ejected through the cutting nozzle 4 to form a high-temperature flame for cutting operations. During or after the operation, if it is found that the cutting effect is not good or the cutting angle needs to be adjusted, the user can use the adjustment mechanism again for fine-tuning to adapt to different cutting requirements or improve the operation feel.
[0028] The following illustrates this application through a specific embodiment.
[0029] A copper pipe dedicated to a cutting torch, comprising a handle 1. A high-pressure oxygen pipe 2 and an acetylene pipe 3 are respectively installed above and below one end of the handle 1. The ends of the high-pressure oxygen pipe 2 and the acetylene pipe 3 away from the handle 1 are connected to a cutting nozzle 4. On both sides of the upper end of the outer surface of the high-pressure oxygen pipe 2, there are respectively a first upper support block 5 and a second upper support block 6. On both sides of the lower end of the outer surface of the acetylene pipe 3, there are respectively a first lower support block 7 and a second lower support block 8 corresponding to the first upper support block 5 and the second upper support block 6. On the sides of the first upper support block 5 and the first lower support block 7 close to the second upper support block 6 and the second lower support block 8, there are both fixedly connected with threaded rods 12. On one side of the second upper support block 6 and the second lower support block 8, there is a first nut 14 rotatably connected through a rotating shaft and threadedly connected to the outer surface of the threaded rod 12.
[0030] On the front and back sides of the first upper support block 5 and the second upper support block 6, there are both fixedly connected with upper connecting plates 9. On the front and back sides of the first lower support block 7 and the second lower support block 8, there are both fixedly connected with lower connecting plates 10 corresponding to the upper connecting plates 9. A half-threaded rod 11 is connected through the corresponding upper connecting plates 9 and lower connecting plates 10.
[0031] Inside the second upper support block 6 and the second lower support block 8 close to the first upper support block 5 and the first lower support block 7, there are both provided with grooves 13. One side of the first nut 14 is rotatably connected to the outer surface of the groove 13 through a rotating shaft. One end of the threaded rod 12 is threadedly penetrated through the first nut 14 and extends into the inside of the groove 13.
[0032] By placing the first upper support block 5 and the second upper support block 6 on the upper end of the high-pressure oxygen pipe 2, and then rotating the first nut 14, so that the first nut 14 is threadedly rotatably connected to the outer surface of the threaded rod 12, the distance between the two support blocks can be adjusted. Then, the first lower support block 7 and the second lower support block 8 are adjusted in the same way to adjust the distance between them, and the upper and lower support blocks on both sides are made to correspond, so that the position between the support blocks can be adjusted according to the lengths of the high-pressure oxygen pipe 2 and the acetylene pipe 3.
[0033] The upper end of the half-threaded rod 11 is threadedly penetrated through the upper connecting plate 9, and above the upper connecting plate 9, there is a second nut 15 rotatably connected and threadedly connected to the half-threaded rod 11. On both sides of the outer surface of the half-threaded rod 11 close to the bottom end, there are both provided with receiving grooves 1102. At the bottom ends of the two receiving grooves 1102, there are both hinged with limiting clamping rods 17 inclined outward, and the ends of the limiting clamping rods 17 away from the hinge are in contact with the bottom end of the lower connecting plate 10.
[0034] By passing the semi-threaded rod 11 through the corresponding upper connecting plate 9 and lower connecting plate 10 in sequence, when the limiting clamping rods 17 on both sides of the bottom end of the semi-threaded rod 11 penetrate and extend to the bottom end of the lower connecting plate 10, they expand towards both sides and abut against the bottom end of the lower connecting plate 10. Subsequently, the second nut 15 is rotated so that the bottom end of the second nut 15 contacts the upper end of the upper connecting plate 9, thereby connecting and fixing the upper support block and the lower support block, and playing a certain role in strengthening and protecting the high-pressure oxygen pipe 2 and the acetylene pipe 3.
[0035] A strip-shaped groove 1101 is formed in the middle of the upper end of the semi-threaded rod 11. An activity rod 16 that penetrates and extends to the top end of the semi-threaded rod 11 is movably connected inside the strip-shaped groove 1101. A connecting rod 18 is fixedly connected to the bottom end of the activity rod 16. An extension groove 1103 that is connected and communicated with the strip-shaped groove 1101 is formed at the bottom end inside the strip-shaped groove 1101. The connecting rod 18 is movably connected inside the extension groove 1103. A spring 19 is fixedly connected between the bottom end of the activity rod 16 and the bottom end of the strip-shaped groove 1101, and the spring 19 is wound around the outer surface of the connecting rod 18. Driving grooves 1601 are formed on both sides of the activity rod 16 near one end of the connecting rod 18. Connecting blocks 1701 that penetrate and extend to the inside of the strip-shaped groove 1101 are fixedly connected to the hinged ends of the two limiting clamping rods 17 and on the opposite sides. The two connecting blocks 1701 are both clamped inside the driving grooves 1601.
[0036] By pressing down the activity rod 16, the activity rod 16 drives the connecting rod 18 to move towards the inside of the extension groove 1103 and compresses the spring 19. Then, through the movement of the activity rod 16, the driving groove 1601 is driven to move downward, and the connecting block 1701 drives the limiting clamping rod 17 to contract towards the inside of the storage groove 1102, so that the semi-threaded rod 11 can be pulled out from the inside of the upper connecting plate 9 and the lower connecting plate 10, and the upper support block and the lower support block are separated from each other.
[0037] When the copper pipe dedicated to the cutting torch is in use, by placing the first upper support block 5 and the second upper support block 6 on the upper end of the high-pressure oxygen pipe 2, and then rotating the first nut 14, the first nut 14 is threadedly rotated and connected to the outer surface of the threaded rod 12, so that the distance between the two support blocks can be adjusted. Then, the first lower support block 7 and the second lower support block 8 are adjusted in the same way to adjust the distance between them, and the upper and lower support blocks on both sides are made to correspond, so that the position between the support blocks can be adjusted according to the lengths of the high-pressure oxygen pipe 2 and the acetylene pipe 3;
[0038] Next, the semi-threaded rod 11 sequentially passes through the corresponding upper connecting plate 9 and lower connecting plate 10. When the limit clamping rods 17 on both sides of the bottom end of the semi-threaded rod 11 penetrate and extend to the bottom end of the lower connecting plate 10, they respectively open towards both sides and abut against the bottom end of the lower connecting plate 10. Subsequently, the second nut 15 is rotated so that the bottom end of the second nut 15 contacts the upper end of the upper connecting plate 9, thereby connecting and fixing the upper support block and the lower support block, and playing a certain role in strengthening and protecting the high-pressure oxygen pipe 2 and the acetylene pipe 3;
[0039] When it is necessary to disassemble between the upper support block and the lower support block, by pressing down the movable rod 16, the movable rod 16 drives the connecting rod 18 to move towards the inside of the extension groove 1103 and compresses the spring 19. Then, through the movement of the movable rod 16, the driving groove 1601 is driven to move downward, and the connecting block 1701 drives the limit clamping rod 17 to contract towards the inside of the receiving groove 1102, so that the semi-threaded rod 11 can be withdrawn from the inside of the upper connecting plate 9 and the lower connecting plate 10, and the upper support block and the lower support block are separated.
[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
