Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, and in particular to a boiler pipeline connection mechanism. Background Technology
[0002] A boiler pipe connection mechanism is a device specifically designed for connecting boiler pipes. It aims to achieve stable connection of boiler pipes, ensure the reliability and sealing of the connection, thereby guaranteeing the safe and efficient operation of the boiler system, improving the safety and flexibility of boiler pipe connections, and has broad application prospects and market value.
[0003] A typical boiler pipe connection mechanism consists of a support mechanism, pipes, and a connection mechanism. During use, the support mechanism provides stable support for the pipes through support rods and positioning rods. The pipes serve as channels for medium transportation, and the connection between pipes is achieved through the connection of the left and right connecting pipes. The connection mechanism achieves rapid pipe connection through the sliding block and spring of the splicing mechanism.
[0004] However, in some existing technologies, the traditional connection method usually requires manual alignment, tightening of bolts or threads, which is complicated and time-consuming. Especially in complex environments such as high temperature and high pressure, the difficulty and risk of manual operation are further increased, resulting in low docking efficiency. Therefore, a boiler pipe docking mechanism is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a boiler pipe docking mechanism, which aims to improve the problem that some existing devices cannot quickly dock two pipes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A boiler pipe connection mechanism includes a pipe body, a left connecting pipe fixedly connected to the outside of the pipe body, a right connecting pipe fixedly connected to the outside of the pipe body, a splicing mechanism provided inside the left connecting pipe, and an adjustment mechanism provided at the bottom of the left connecting pipe. The splicing mechanism includes multiple support blocks. The external parts of the multiple support blocks are fixedly connected to the inside of the left connecting tube. A guide post is fixedly connected to one side of the external parts of the multiple support blocks. A spring is sleeved on the outside of each of the multiple guide posts. A sliding block is fixedly connected to the outside of the multiple springs, i.e., the side away from the support blocks. A placement groove is opened inside the sliding block. A docking plate is fixedly connected to the outside of the right connecting tube, i.e., the side near the outside of the left connecting tube. A slot is opened inside the docking plate. A positioning component is slidably connected to the top of the docking plate. As a further description of the above technical solution: The positioning component includes a positioning groove, the outside of which is slidably connected to the top of the docking plate, and a sliding rod is provided inside the docking plate. The bottom of the positioning groove passes through the top of the left connecting tube and is slidably connected inside the positioning groove. As a further description of the above technical solution: The adjustment mechanism includes two support rods, the tops of which are fixedly connected to the inside of the left connecting tube, and two positioning rods are slidably connected to the outside of the left connecting tube. As a further description of the above technical solution: Two support columns are provided at the bottom of the left connecting tube, and the outside of the two support rods are slidably connected to the inside of the two support columns respectively; As a further description of the above technical solution: Support columns are fixedly connected to the outer adjacent sides of the two support rods, and support plates are slidably connected to the outer sides of the support columns; As a further description of the above technical solution: The support plate has a sliding groove inside, and the outside of the sliding groove is slidably connected to the outside of the support column; As a further description of the above technical solution: A top block is fixedly connected to the top of the support plate, i.e., the outside away from the left connecting pipe, and the outside of the top block is at the bottom of the right connecting pipe.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the two sides of the docking plate will gradually squeeze the sliding block inside the left connecting tube. After being squeezed, the sliding block moves towards the support block to ensure a smooth docking process. When the docking plate is completely slid into the left connecting tube, the sliding block is reset under the elastic force of the spring and engages in the slot of the docking plate, thereby realizing the rapid docking of the left connecting tube and the right connecting tube and ensuring the reliability of the connection.
[0008] 2. In this utility model, when the position of the right connecting pipe needs to be adjusted, the support rod slides inside the support column, and the positioning rod is fixed by sliding to prevent the support rod from falling off, ensuring the stability of the support. The support plate slides outside the support column through the sliding groove, applying pressure to the support column to generate a prying action, thereby realizing the fine adjustment of the right connecting pipe and ensuring the accuracy of the docking. Under the prying action of the support plate, the top block applies an upward thrust to the bottom of the right connecting pipe, adjusting the position and angle of the right connecting pipe, further enhancing the stability and reliability of the docking.

[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 2 to 4 The present invention provides an embodiment of a boiler pipe docking mechanism, comprising a pipe body 1, a left connecting pipe 2 fixedly connected to the outside of the pipe body 1, which is designed to provide good support capacity, a right connecting pipe 3 fixedly connected to the outside of the pipe body 1, which is designed to dock with the left connecting pipe 2, a splicing mechanism 4 provided inside the left connecting pipe 2, and an adjustment mechanism 6 provided at the bottom of the left connecting pipe 2. The splicing mechanism 4 includes multiple support blocks 41, designed to provide support. The support blocks 41 are externally fixedly connected to the inside of the left connecting tube 2. Guide posts 42 are fixedly connected to one side of each support block 41, providing support for the guide posts 42. Springs 43 are fitted onto the outside of each guide post 42, providing elasticity and preventing displacement. Sliding blocks 46 are fixedly connected to the outside of each spring 43, away from the support blocks 41, providing limiting and locking capabilities. The sliding blocks 46 have internal placement grooves 47 for placement. A docking plate 44 is fixedly connected to the outside of the right connecting tube 3, near the outside of the left connecting tube 2, allowing for rapid docking. The docking plate 44 has a rectangular groove 45 inside. When the docking plate 44 slides inside the left connecting tube 2, the two sides of the docking plate 44 will press against the placement groove 47 inside the left connecting tube 2. After the placement groove 47 is engaged with the outside of the groove 45, the spring 43 can return to its original position and press, thus fixing the docking plate 44 and realizing the quick docking of the left connecting tube 2 and the right connecting tube 3. The top of the docking plate 44 is slidably connected to a positioning component 5, which includes a slide rod 502. Its design can provide sliding and support capabilities. The outside of the slide rod 502 is slidably connected to the top of the docking plate 44. The docking plate 44 has a positioning groove 501 inside. The positioning groove 501 can slide and fix the slide rod 502, thus fixing the docking plate 44. The bottom of the slide rod 502 passes through the top of the left connecting tube 2 and is slidably connected inside the positioning groove 501.
[0013] Reference Figure 1 and Figure 5The adjusting mechanism 6 includes two support rods 61, designed to provide support. The tops of the two support rods 61 are fixedly connected to the inside of the left connecting tube 2. Two positioning rods 62 are slidably connected to the outside of the left connecting tube 2, designed to provide positioning capabilities, allowing the support rods 61 to be slidably fixed. Two support columns 63 are provided at the bottom of the left connecting tube 2, designed to provide sliding space. The positioning rods 62 slide on the outside of the left connecting tube 2, allowing the support rods 61 to be fixed inside the support columns 63, preventing them from falling off. The outside of the two support rods 61 are slidably connected to the inside of the two support columns 63 respectively. Support columns 63 are fixedly connected to adjacent sides of the outside of the two support rods 61, designed to provide good support capabilities. A support plate 64 is slidably connected to the support column 63, which prevents the support plate 64 from falling off. The support plate 64 has a groove 65 inside, which provides sliding space so that the support plate 64 can slide outside the support column 63 through the groove 65. The support column 63 is inside the groove 65, so the top inner wall of the support plate 64 can press against the support column 63 to pry it. The outside of the groove 65 is slidably connected to the outside of the support column 63. The top of the support plate 64, away from the left connecting pipe 2, is fixedly connected to a top block 66, which provides good pushing ability. The prying of the support plate 64 can lift the right connecting pipe 3 upward with the top block 66. The outside of the top block 66 is at the bottom of the right connecting pipe 3.
[0014] Working principle: First, the docking plate 44 of the right connecting pipe 3 is slidably connected inside the left connecting pipe 2. When the right connecting pipe 3 moves closer to the left connecting pipe 2, the two sides of the docking plate 44 gradually press the sliding block 46 inside the left connecting pipe 2. After being pressed, the sliding block 46 moves towards the support block 41, while compressing the spring 43. When the docking plate 44 is completely slid into the left connecting pipe 2, the sliding block 46 is reset under the elastic force of the spring 43 and engages in the slot 45 of the docking plate 44, thereby achieving rapid docking of the left connecting pipe 2 and the right connecting pipe 3. Next, the slide rod 502 slides on the top of the docking plate 44 and passes through the top of the left connecting pipe 2, sliding into the positioning groove 501. The slide rod 502, through sliding and fixing, ensures the stability of the docking plate 44, further enhancing the stability of the docking. When the position of the right connecting pipe 3 needs to be adjusted, the support rod 61 slides within the support column 63 and is fixed by the sliding of the positioning rod 62 to prevent the support rod 61 from falling off. The support plate 64 slides outside the support column 63 through the sliding groove 65, while simultaneously applying pressure to the support column 63, generating a prying action. Under the prying action of the support plate 64, the top block 66 applies an upward thrust to the bottom of the right connecting pipe 3, thereby adjusting the position and angle of the right connecting pipe 3 to ensure the stability and accuracy of the docking.
