Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage engineering, and in particular to an auxiliary connection device for water supply and drainage pipes. Background Technology

[0002] Pipeline auxiliary connection devices for water supply and drainage are functional equipment that assist in completing pipeline connections. Through mechanical structures, they achieve precise positioning, clamping, and adjustment of pipelines. Using these devices can effectively improve connection accuracy and stability, avoid problems such as interface misalignment and leakage, significantly improve construction efficiency, reduce manual labor intensity and costs, adapt to the construction needs of complex environments and special pipeline types, meet functions such as vibration reduction and noise reduction, and safety sealing, and ensure that construction complies with engineering specifications, reduce later maintenance costs, and ensure the long-term safe and stable operation of water supply and drainage systems. They are an indispensable and important tool in modern water supply and drainage engineering.

[0003] Existing auxiliary connection devices for water supply and drainage pipelines mainly fix the pipelines by clamping and positioning structures, and achieve precise alignment and movement of the pipelines with the help of adjustment mechanisms and power drive systems. During connection, pressure transmission structures are used to apply force evenly to the interface, and sealing components are used to achieve a tight connection. At the same time, support and reinforcement designs are adopted to enhance stability for complex scenarios. Some devices also have vibration reduction and noise reduction functions, thereby improving the accuracy, efficiency and sealing of pipeline connections.

[0004] In the actual use of auxiliary connection devices for water supply and drainage pipelines, the problem of insufficient adaptability of the equipment to pipe sizes is quite prominent. Most existing devices adopt fixed-specification clamping structures. When dealing with pipes of different diameters such as DN20 to DN200, it is often necessary to stop the machine to replace the entire set of clamping components or adjust the positioning brackets. For example, in some municipal engineering projects, PE pipes and cast iron pipes need to be connected in the same construction section. Operators need to disassemble the original arc clamps and replace them with corresponding specification parts. Each replacement takes about 20 to 30 minutes. If the project involves the alternating construction of multiple specifications of pipes, frequent replacement of parts will lead to a decrease in construction efficiency of more than 40%. This limitation of one machine for one use not only increases the cost of manual operation, but also reduces the continuity of assembly line operations due to equipment idleness, which is in obvious contradiction with the construction requirements of high efficiency and standardization in modern water supply and drainage engineering. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary connection device for water supply and drainage pipes, which aims to improve the problem of needing to replace different devices to fix pipes of different sizes during equipment use.

[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] One of the fixing rods has a fixing plate fixedly connected to one end, and the other fixing rod has a docking plate fixedly connected to one end.

[0014] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] Each of the fixed pins is fixedly connected to a limiting plate on its outer wall, and the outer wall of each limiting plate is slidably connected to the inside of the fixed column.

[0020] As a further description of the above technical solution:

[0021] The fixed column is equipped with a plurality of springs II. One end of each spring II is fixedly connected to the inside of the fixed column, and the other end of each spring II is fixedly connected to one end of the fixed pin.

Detailed Implementation

[0032] 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.

[0033] Reference Figures 1-3 An embodiment of this utility model provides: an auxiliary connection device for water supply and drainage pipes, including multiple pipes 1, each pipe 1 having a fixing ring 2 at its bottom for fixing the pipe 1, each fixing ring 2 having a rotating shaft 3 rotatably connected to one end for providing mechanical support for the rotation of the fixing ring 2, each rotating shaft 3 having a fixing ring 4 fixedly connected to its outer wall for fixing the pipe 1, each fixing ring 2 having a connecting component at one end for connecting the fixing ring 2 and the fixing ring 4, each fixing ring 2 and the fixing ring 4 having a fixing box 9 fixedly connected to its outer wall for accommodating the fixing component, each fixing box 9 having a fixing component inside for fixing the pipe 1 inside the fixing ring 2 and the fixing ring 4;

[0034] Each fixing component includes a connecting rod 10, multiple sliding posts 11, and multiple springs 12. The outer wall of the connecting rod 10 is slidably connected to the inside of the fixing box 9 for connecting the soft rubber ring 14. One end of each sliding post 11 is fixedly connected to the outer wall of the connecting rod 10, limiting the range of movement of the connecting rod 10. Each spring 12 is disposed on one side of the sliding post 11, providing elastic force to the connecting rod 10. One end of each spring 12 is fixedly connected to the inside of the sliding post 11, and the other end of each spring 12 is fixedly connected to the inside of the fixing box 9. A limiting plate 13 is fixedly connected to one end of each connecting rod 10 to limit the range of movement of the soft rubber ring 14. The other end is fixedly connected with a soft rubber ring 14 for fixing the pipe 1. Each connecting component includes a rotating block 5, a threaded post 6, multiple connecting plates 7 and a nut 8. One side of the rotating block 5 is fixedly connected to one end of the fixing ring 2, for connecting the threaded post 6 and providing mechanical support for its rotation. One end of the threaded post 6 is fixedly connected inside the rotating block 5, and cooperates with the nut 8 to fix the fixing ring 2 and the fixing ring 4. One side of each connecting plate 7 is fixedly connected to one end of the fixing ring 4, and cooperates with the rotating block 5 to fix the fixing ring 2 and the fixing ring 4. The inner wall of the nut 8 is threaded to the outer wall of the threaded post 6, and cooperates with the threaded post 6 to fix the fixing ring 2 and the fixing ring 4.

[0035] Specifically, first, firmly grasp the second fixing ring 4 with both hands and gently rotate it clockwise to slowly open the second fixing ring 4. Then, place the pipe 1 to be connected smoothly inside the first fixing ring 2. Next, apply force with both hands to precisely fasten the second fixing ring 4. In an instant, the soft rubber ring 14 wrapped inside the two rings slowly contracts under the even pressure of the outer wall of the pipe 1. Its flexible material closely fits the contour of the pipe 1. At the same time, the contraction of the soft rubber ring 14 drives the connecting rod 10 to move inward. With the ingenious linkage structure, the pipe 1 is firmly fixed inside the first fixing ring 2 and the second fixing ring 4, forming an indestructible clamping effect.

[0036] Reference Figure 4 and Figure 5Each fixing ring 12 has a connecting block 15 fixedly connected to one side for connecting fixing rods 16. Each connecting block 15 has a fixing rod 16 fixedly connected to its bottom for connecting the two sets of fixing rings 12 and 4 together. One fixing rod 16 has a fixing plate 17 fixedly connected to one end for connecting to the mating plate 18, and the other fixing rod 16 has a mating plate 18 fixedly connected to one end for connecting to a fixing post 19. A fixing post 19 is fixedly connected to the top of the fixing plate 17 for fixing the two fixing rods 16. The outer wall of the fixing post 19 passes through the interior of the mating plate 18. The internal sliding connection of the 9 has multiple fixing pins 20 for fixing the docking plate 18 and the fixing plate 17. The fixing pins 20 are arranged in a symmetrical array inside the fixing column 19. Each fixing pin 20 has a limit plate 21 fixedly connected to its outer wall to limit the movement range of the fixing pin 20. The outer wall of each limit plate 21 is slidably connected inside the fixing column 19. The fixing column 19 has multiple springs 22 inside to provide elastic force for the fixing pins 20. One end of each spring 22 is fixedly connected inside the fixing column 19, and the other end of each spring 22 is fixedly connected to one end of the fixing pin 20.

[0037] Specifically, during the connection operation, first carefully align the fixing plate 17 and the docking plate 18, hold them steadily with both hands, and slowly interlock them. As the fixing plate 17 and the docking plate 18 gradually approach each other, the fixing post 19 is precisely inserted into the pre-set hole in the docking plate 18. During the insertion process, the fixing pin 20 is evenly and forcefully squeezed by the inner wall of the docking plate 18 and slowly retracts into the groove inside the fixing post 19. When the fixing plate 17 and the docking plate 18 are completely fitted together, the spring 22, which is ready to be released, instantly releases a strong elastic force, pushing the fixing pin 20 to pop out quickly and accurately lock into the top of the docking plate 18, connecting the two fixing rods 16 tightly and firmly together to form a strong and reliable connection structure.

[0038] Working principle: In the process of using the auxiliary connection device for water supply and drainage pipes, first align the fixing plate 17 and the docking plate 18 and fasten them together so that the fixing post 19 is inserted into the docking plate 18. The fixing pin 20 is squeezed into the fixing post 19 by the inner wall of the docking plate 18. When the fixing plate 17 and the docking plate 18 are completely in contact, the fixing pin 20 is popped out by the action of the second spring 22 to connect the two fixing rods 16 together. Then, start the installation of pipe 1. First, hold the second fixing ring 4 and rotate it to open it. Then, place pipe 1 inside the first fixing ring 2. Then, fasten the first fixing ring 2 and the second fixing ring 4 so that the soft rubber ring 14 is squeezed by the outer wall of pipe 1 to shrink, so that the connecting rod 10 moves inward and fixes pipe 1 inside the first fixing ring 2 and the second fixing ring 4, thereby completing the fixing and installation of pipe 1.

[0039] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
