Technical Field
[0001] This utility model relates to the field of pipeline connection structure technology, and in particular to a boiler pipeline connection structure. Background Technology
[0002] A boiler pipe connection structure is a device used to connect pipes in a boiler system. It can achieve a stable connection between pipes, ensure the sealing and stability of the connection, and guarantee the safe and efficient operation of the boiler system. It tightly connects different pipes in the boiler system to form a connected channel, allowing the medium (such as water, steam, etc.) to flow smoothly between the pipes.
[0003] A typical boiler piping connection structure consists of connecting rings, support frames, and pipes. Therefore, the connecting ring is a key component in boiler piping connections, usually a circular or square structure with connecting holes. It is connected to the connecting rings on adjacent pipes using bolts, nuts, and other fasteners to form a tight, sealed channel. The support frame mainly serves to support and fix the pipes, and is generally made of metal, possessing sufficient strength and stability. The pipes are the channels for transporting the medium in the boiler system, and are usually made of metal materials such as steel pipes, possessing a certain degree of pressure resistance and corrosion resistance.
[0004] However, some existing devices are complex in structure and cumbersome in operation when connected, requiring a lot of time and manpower to align and fix the pipes, which makes it difficult to meet the needs of rapid assembly and maintenance of boiler systems. The lack of effective limiting and guiding mechanisms during the docking process makes the pipes prone to deviation or shaking, and cannot guarantee the stability and accuracy of the docking. Therefore, a boiler pipe connection structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a boiler pipe connection structure, which aims to improve the problem that some devices in the prior art cannot quickly and smoothly connect pipes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A boiler pipe connection structure includes two fixed rings, a rotating column is rotatably connected inside the two fixed rings, limit rings are fixedly connected to the outer two sides of the rotating column, a connecting mechanism is provided on the outer two sides of the two fixed rings, a connecting plate is fixedly connected to the top of the two fixed rings, and a fixing mechanism is provided inside the connecting plate. The connecting mechanism includes two support blocks, which are fixedly connected to the outer sides of the fixed ring. The two support blocks are rotatably connected to the inner sides of the two support blocks. The two support blocks are fixedly connected to the outer sides of the two support blocks. The two support blocks are slidably connected to the inner sides of the two support blocks. The pull rods are provided with grooves inside the pull rods. The grooves are slidably connected to the inner sides of the press rods. Rotating components are fixedly connected to the outer sides of the fixed ring. Guide components are fixedly connected to the top of the two fixed rings. As a further description of the above technical solution: The rotating assembly includes two connecting blocks, the two connecting blocks are fixedly connected to the outer sides of the fixed ring, and the two connecting blocks are rotatably connected to the inner sides of the movable column. The other side of the two pull rods is fixedly connected to the outside of the movable column. As a further description of the above technical solution: The guide assembly includes two support blocks, which are externally fixedly connected to the outer sides of the two fixed rings, and guide rods are slidably connected inside the two support blocks. As a further description of the above technical solution: The fixing mechanism includes two bolts, the outer sides of which are threaded to the inside of the connecting plate, and multiple limiting posts are slidably connected to one side of the outer side of the two connecting plates; As a further description of the above technical solution: The two bolts are externally threaded with nuts, and the plurality of limiting posts are externally slidably connected to the interior of the two connecting plates; As a further description of the above technical solution: A support plate is fixedly connected to one side of the outer side of the plurality of limiting posts, and a locking block is fixedly connected to the outer side of the support plate, that is, the outer side near the nut.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by bending the pressing rod, the horizontal column slides in the groove of the pull rod, causing the pull rod to move. Since the pull rod is connected to the movable column and the movable column rotates in the connecting block, the fixed ring moves towards the support block. At the same time, when the two fixed rings approach each other, the guide rod slides in the support block to maintain balance, realizing quick pipe connection. This design is convenient to operate. The pipe connection can be completed by simply bending the pressing rod, saving time and effort. Moreover, the cooperation between the guide rod and the support block ensures the stability of the connection and avoids the offset or shaking of the pipe during connection.
[0008] 2. In this utility model, when the fixing ring is closed and fixed, the bolt passes through the inside of the connecting plate and is threaded into the inside of the nut, causing the two connecting plates to move closer to each other and thus fixing the pipe. During this process, the limiting post slides inside the connecting plate and passes through the nut to limit the nut and prevent it from loosening. At the same time, the fixing block rotates with the bolt and passes through the nut and the connecting plate, further sliding the support plate. The dual limiting effect of the limiting post and the locking block effectively prevents the connection from loosening. Attached Figure Description

[0011] 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.
[0012] Reference Figures 1 to 3 The present invention provides an embodiment of a boiler pipe connection structure, comprising two fixed rings 1, with a rotating column 3 rotatably connected inside the two fixed rings 1. The design provides good rotation capability, allowing each fixed ring 1 to open and close from the top. Limiting rings 2 are fixedly connected to the outer sides of the rotating column 3, which are designed to limit the rotation capability of the rotating column 3. Connecting mechanisms 4 are provided on the outer sides of the two fixed rings 1. Connecting plates 5 are fixedly connected to the top of the two fixed rings 1, which are designed to provide good connection capability. At the same time, two connecting plates 5 are fixedly connected to the top of each fixed ring 1, two of which can fit together. A fixing mechanism 6 is provided inside the connecting plate 5. The connecting mechanism 4 includes two support blocks 41, which are designed to provide good support capabilities and are fixed on both sides of one of the fixed rings 1. The two support blocks 41 are externally fixedly connected to the two sides of the fixed ring 1. The two support blocks 41 are internally rotatably connected to a support column 42, which can rotate through the support of the support blocks 41. The two support columns 42 are externally fixedly connected to a pressing rod 43. The support column 42 is internally equipped with a horizontal column, which is designed to provide pressing capability. When pressing the pressing rod 43, the angle of the pressing rod 43 can be adjusted by the rotation capability provided by the support column 42. The two pressing rods 43 are internally slidably connected to a pull rod 44, which is designed to provide connection capability. The pull rod 44 is internally provided with a groove 45, which is designed to provide sliding space, allowing the horizontal column inside the pressing rod 43 to slide. When the pressing rod 43 is pried, the horizontal column pulls the groove 45, causing the pull rod 44 to slide. The groove 45 is internally slidably connected to the inside of the pressing rod 43. Rotating assemblies are fixedly connected to both outer sides of the fixed ring 1. Each rotating assembly includes two connecting blocks 46, designed to provide support on the other two outer sides. The two connecting blocks 46 are fixedly connected to the outer sides of the fixed ring 1. Movable columns 47 are rotatably connected inside the two connecting blocks 46, allowing the movable columns 47 to rotate within them. The other side of the two pull rods 44 is fixedly connected to the outside of the movable columns 47. Their design allows the fixed ring 1 connected to the connecting blocks 46 to rotate when the pressing rod 43 is pulled. The fixed ring 1 of the support block 41 moves in the direction of the fixed ring 1, so that the fixed ring 1 can pull the pipe closer to each other for connection. The top of the two fixed rings 1 is fixedly connected to the guide assembly, which includes two support blocks 48. The design is that they are installed on both sides of the outside of each fixed ring 1 to provide good support. The two support blocks 48 are fixedly connected to the outside of the two fixed rings 1. The guide rod 49 is slidably connected inside the two support blocks 48. When the two fixed rings 1 are close to each other, the guide rod 49 will slide inside the two support blocks 48 to maintain balance during connection.
[0013] Reference Figures 4 to 6 The fixing mechanism 6 includes two bolts 61, designed to provide a stable connection. The outer surfaces of the two bolts 61 are threaded into the interior of the connecting plate 5. Multiple limiting posts 62 are slidably connected to the outer side of the two connecting plates 5, designed to provide good limiting capability. Nuts 65 are threaded onto the outer surfaces of the two bolts 61. After the bolts 61 are threaded into the nuts 65, the two connecting plates 5 on the fixing ring 1 can be brought closer together, thus fixing the pipe placed inside the fixing ring 1. The multiple limiting posts 62 are slidably connected to the outer surfaces of the connecting plates 61. The two connecting plates 5 are connected inside each other and are slidably connected to the inside of the nut 65 through the outside of the limiting post 62. This allows the nut 65 to be limited after the threaded connection, and the limiting post 62 can slide inside the connecting plate 5. A support plate 67 is fixedly connected to the outside of the multiple limiting posts 62. Its design can provide good support and support the limiting posts 62. A locking block 66 is fixedly connected to the outside of the support plate 67, that is, the outside of the nut 65. Its design can provide good support and good fitting ability. Two bolts 61 are fixedly connected to a fixing block 63 on the outer side near the nut 65. The design provides good connection capability, so that when the bolt 61 can drive the fixing block 63 through the inside of the nut 65, the two fixing blocks 63 have rectangular grooves 64 inside, which provide good locking capability. After the fixing block 63 passes through the inside of the connecting plate 5 and the nut 65, the sliding support plate 67 can lock the locking block 66 into the inside of the rectangular groove 64. At the same time, multiple limiting posts 62 pass through the inside of the nut 65 to limit the nut 65 and prevent loosening. The outside of the locking block 66 is slidably connected to the inside of the rectangular groove 64, and the outside of the multiple limiting posts 62 is sequentially slidably connected to the inside of the nut 65 and the connecting plate 5.
[0014] Working principle: First, the pressing rod 43 is turned, causing the horizontal column to slide within the groove 45 of the pull rod 44, thereby driving the pull rod 44 to slide. Since the other side of the pull rod 44 is fixedly connected to the outside of the movable column 47, and the movable column 47 is rotatably connected inside the connecting block 46, as the pull rod 44 slides, the movable column 47 rotates within the connecting block 46, thereby pulling the fixed ring 1 towards the fixed ring 1 of the connecting support block 41. At the same time, the two fixed rings 1 move closer to each other, and the guide rod 49 slides inside the support block 48, maintaining connection balance and achieving rapid connection of the two pipes. When the fixing ring 1 is closed and fixed, the bolt 61 passes through the interior of the connecting plate 5 and is then threaded into the interior of the nut 65, bringing the two connecting plates 5 closer together and thus fixing the pipe inside the fixing ring 1. During the process of the bolt 61 passing through the nut 65, the limiting post 62 slides inside the connecting plate 5 and passes through the interior of the nut 65, limiting the nut 65 and preventing it from loosening. Simultaneously, the fixing block 63 passes through the interior of the nut 65 and the connecting plate 5 as the bolt 61 rotates. At the same time, the sliding support plate 67 drives the locking block 66 to engage with the rectangular groove 64 of the fixing block 63, thereby enhancing the fixing effect. This design ensures that the pipe connection can prevent loosening during use.
[0015] 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.
