[0035] Specifically, the auxiliary connection mechanism 2 ensures system stability, the arc plate 201 is in close contact with the pipe, the arc grooves 202 on both sides support the sliding column 1 203, the connecting bracket 205 enhances flexibility, the bottom fixing plate 206 of the bracket 205 connects to the connecting bracket 1 204, the double sliding structure improves adaptability, the pulley 208 reduces friction and allows for quick movement, the push handle 26 facilitates operation, the bolt 4 27 is used to fix the fixing plate 206, the outer wall of the fixing ring 2 9 has the thread of the bolt 3 24, the outer wall of the bolt 3 24 is equipped with a gasket 25, the gasket 25 ensures the connection sealing and provides support for the stable operation of the system.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The top of the fixing ring 2 9 is threaded with a bolt 18. The top of the bolt 18 has a prism groove 19, which not only increases the contact area with the prism groove 19, but also enhances the stability of the connection and makes it easy for workers to quickly connect the rotating fastening device. The prism groove 19 is provided with a pentagonal prism 20. The top of the pentagonal prism 20 is fixedly connected to a fixing block 21. The top of the fixing block 21 is rotatably connected to a bolt 22. The outer wall of the bolt 22 is rotatably connected to a handle 23. The outer wall of the fixing ring 1 7 has an annular groove 16. The annular groove 16 is installed with a sealing ring 17. This not only simplifies the operation process for operators, but also significantly improves work efficiency.

[0037] Specifically, a pentagonal prism 20 is installed inside the prism groove 19. The pentagonal cross-section of the pentagonal prism 20 not only increases the contact area with the prism groove 19 and improves the stability of the connection, but also facilitates workers to quickly connect and rotate the fastening structure. A fixing block 21 is fixedly connected to the top of the pentagonal prism 20. A bolt 22 is rotatably connected to the top of the fixing block 21. As a key component for connection and fastening, the bolt 22 is also rotatably connected to a handle 23 on its outer wall. The design of the handle 23 facilitates the operation of the operator and improves work efficiency.

[0038] Looking at the outer wall design of the retaining ring 7, an annular groove 16 is created, a design that seems tailor-made for the sealing ring 17. The sealing ring 17, a crucial component for preventing leakage and ensuring sealing performance, is cleverly installed inside the annular groove 16. This design not only effectively improves the overall sealing performance of the structure but also ensures the stable operation of the mechanical equipment under harsh conditions through its excellent sealing effect.

[0039] Working principle: First, the inner walls of pressure pipe 1 are fixedly connected to fixed posts 3 at the upper and lower ends. Fixed posts 3 serve as key engagement points in the connection structure, ensuring stability and preventing deformation during use, and guaranteeing precise connection with subsequent components. Next, an annular groove 5 is formed on the outer wall of pressure pipe 4. Then, an extension pipe 6 is connected to the left end of the outer wall of pressure pipe 4. The introduction of extension pipe 6 not only enhances the airtightness of the pipe connection, but also features a fixed ring 7 fixedly connected to its outer wall. The groove 8 on the left side of the outer wall of fixed ring 7 forms a perfect engagement with the fixed post 3 on the inner wall of pressure pipe 1, simplifying the installation process and greatly improving the stability of the connection. A second fixed ring 9 is also connected to the outer wall of pressure pipe 1 via threads. The inner wall is fixedly connected to the fixing ring 10. The outer wall of the fixing ring 10 has multiple circular holes 11 at equal intervals. The springs 13 and balls 12 installed inside these circular holes 11 form a unique buffer and self-locking mechanism. When the two pipes are engaged with the fixing post 3 through the fixing ring 7, the tight fit between the fixing ring 2 9 and the fixing ring 3 10 makes the balls 12 stick tightly to the connection interface under the elastic force of the spring 13. This design can not only effectively achieve quick docking and prevent the connection from loosening or falling off, but also effectively prevent media leakage even under high pressure, high temperature or corrosive fluid under the tight contact between the balls 12 and the connection interface. At the same time, the elastic design of the spring 13 can also compensate for the decrease in sealing performance caused by material aging, wear and other factors to a certain extent.

[0040] The auxiliary connecting mechanism 2 has two arc-shaped grooves 202 designed on the left and right sides of the outer wall of the arc-shaped plate 201. These grooves provide sliding tracks for the sliding column 203, allowing it to slide freely within them. This enables the connecting mechanism to make fine adjustments in the horizontal direction. The other end of the sliding column 203 is fixedly connected to a bracket 205, increasing the stability of the structure. The bottom of the bracket 205 is fixedly connected to a fixed plate 206, supporting the entire auxiliary connecting mechanism 2. The top left and right sides of the fixed plate 206 are also fixedly connected to brackets 204, and the tops of these brackets 204 are fixedly connected to the sliding column 207. The sliding column 207 slides on the left and right sides of the inner wall of the arc-shaped groove 202, allowing the auxiliary connecting mechanism 2 to maintain a stable connection even under complex and changing working conditions. Pulleys 208 are installed at the four corners of the fixed plate 206, allowing the connecting mechanism to be easily moved and positioned during maintenance and repair, greatly improving work efficiency.
