Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline connection, and in particular relates to a pipeline with a quick connection assembly. Background Art

[0002] Designing pipes for quick connections in piping systems is crucial in many areas, particularly in hydrological and water quality surveying, industry, construction, chemical engineering, and many other fields. Quick-connect piping can reduce installation time. Traditional threaded or welded connections typically take a long time to complete and may require specialized skills and tools. In some applications, such as hydrological observation, the pipe layout may need to be adjusted based on actual conditions. Quick-connect piping systems can easily accommodate these requirements, increasing system flexibility. Quick-connect piping also offers environmental benefits during installation. Some traditional connection methods, such as welding, may require the use of hazardous chemicals, which quick-connect technology avoids. The ease of disassembly and reuse of quick-connect piping contributes to the efficient use of resources and aligns with modern society's pursuit of sustainable development. Existing detachable pipes are typically assembled using flanges and gaskets. While this assembly method is easy to disassemble, it requires the pipes to be aligned at the same height, making installation inconvenient.

[0003] The existing Chinese patent document with publication number CN118746076A proposes a combined sealed boiler pipe and its assembly method. By utilizing the rapid adjustment of the height adjustment component and connecting it with the front fixing hoop, the height of the sealed pipe can be quickly adjusted by simply rotating the second screw rod, so that the entire adjustment and installation process can be completed by a single person. However, the above-mentioned height adjustment component is an additional structure assembled on the outside of the pipe. In some application scenarios, the presence of the height adjustment component will affect the overall laying of the pipe or the connection of other equipment.

[0004] Therefore, the present invention proposes a pipeline with a quick connection component to solve the problem in the prior art that using additional structures to achieve rapid installation of pipelines will affect the overall laying of the pipeline or the connection of other equipment. By improving the pipeline connection port and modularizing the pipeline connection port, it can not only realize automatic positioning and correction of the pipeline, but also realize rapid installation and sealing locking of the pipeline without affecting other equipment.

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 Please refer to Figures 1 to 20The present invention provides a technical solution: a pipe with a quick connection assembly, comprising a pipe 1, a connecting locking head assembly 2 is provided at one end of the pipe 1, a self-locking fixing assembly 3 is provided at the other side of the pipe 1, the connecting locking head assembly 2 comprises a locking pipe head 21 fixedly mounted at one end of the pipe 1, a sealing guide ring 22 is fixedly mounted on one side of the locking pipe head 21, the self-locking fixing assembly 3 comprises a connecting pipe head 31 fixedly mounted at the other end of the pipe 1, a floating self-locking pipe head 35 is provided on the outer side of the connecting pipe head 31, a mounting guide locking pipe head 36 is fixedly mounted on one side of the floating self-locking pipe head 35, in this embodiment, the connecting The locking head assembly 2 and the self-locking fixing assembly 3 are respectively at the two ends of the pipe 1. When the two pipes 1 are connected front and back, the self-locking fixing assembly 3 of the front pipe 1 and the connecting locking head assembly 2 of the rear pipe 1 form a connecting assembly to achieve rapid connection and self-locking of the two pipes 1. The locking pipe head 21 mainly serves to fix the sealing guide ring 22 and the locking claw limit mounting seat 23 at one end of the pipe 1. The locking claw limit mounting seat 23 mainly serves to install the locking claw 24. The connecting pipe head 31 mainly serves to fix the floating self-locking pipe head 35 and the installation guide locking pipe head 36 at the other end of the pipe 1. The middle part of the installation guide locking tube head 36 is provided with an installation guide groove 361 adapted to the sealing guide ring 22. The outer surface of the locking tube head 21 is fixedly installed with a locking claw limit mounting seat 23. The interior of the locking claw limit mounting seat 23 is fixedly installed with a locking claw 24 through a spring telescopic rod. The locking claw 24 is symmetrically arranged in four groups. The upper upper part of the four groups of locking claws 24 is movably installed with an upper locking boss 241, and the lower lower part of the locking claw 24 is movably installed with a lower locking boss 242. A small gear 243 is rotatably installed in the middle of the inner part of the locking claw 24. The outer surface of the installation guide locking tube head 36 is fixedly installed with a locking claw limit mounting seat 23. The guide ring 37 is installed. The inner surface of the guide ring 37 is provided with a locking groove 371. Round head sealing rings 362 are respectively provided on both sides of the guide groove 361. The round head sealing ring 362 is fixedly installed on the side wall of the guide locking pipe head 36. The side wall of the locking pipe head 21 is provided with a round head sealing groove 211 adapted to the round head sealing ring 362. The inner side wall of the guide locking pipe head 36 is symmetrically and movably provided with an installation correction pad 363. The outer surface of the guide locking pipe head 36 is symmetrically provided with a locking hole 364. In this embodiment, when the two pipes 1 are connected front and back, first seal them. The sealing guide ring 22 is inserted into the installation guide groove 361. The inclined surface of the installation guide groove 361 and the tapered structure of the sealing guide ring 22 play a guiding role in the installation process, and the elastic connection structure provided between the installation correction pad 363 and the inner wall of the installation guide locking pipe head 36 can push the installation correction pad 363 out to contact the inclined surface of the sealing guide ring 22. As the locking pipe head 21 is advanced, the installation correction pads 363 on both sides are movable to adjust the position of the advanced installation of the sealing guide ring 22 to a certain extent, so that the sealing guide ring 22 is fully engaged with the installation guide groove 361. At this time, the installation guide groove 361 is installed. The round head sealing rings 362 on both sides of 61 will be engaged with the inside of the round head sealing groove 211, forming a double-layer sealing effect, which increases the sealing performance of the locking pipe head 21 and the installation guide locking pipe head 36 after installation. After the sealing guide ring 22 is installed in place, the installation correction pad 363 is squeezed by the side wall of the sealing guide ring 22, so that the installation correction pad 363 produces an oblique pushing effect on the inner side of the round head sealing ring 362, further ensuring that the round head sealing ring 362 and the round head sealing groove 211 are tightly and stably engaged to avoid loosening. At this time, the preliminary installation between the locking pipe head 21 and the installation guide locking pipe head 36 is completed. The position of the locking hole 364 in the locking groove 371 is provided with the second locking hole 3711. The sizes of the locking hole 364 and the second locking hole 3711 are respectively adapted to the sizes of the lower locking boss 242 and the upper locking boss 241. The outer wall of the installation guide ring 37 is movably installed with a locking bolt 372 at a position corresponding to the second locking hole 3711. In this embodiment, when the locking pipe head 21 and the installation guide locking pipe head 36 are in the initial installation state, the locking claw 24 and the locking claw limit device are The spring rod between the mounting seat 23 is still in a naturally extended state. The upper locking protrusion 241 and the lower locking protrusion 242 will be compressed due to the initial assembly of the locking pipe head 21. After the initial assembly, the upper locking protrusion 241 is naturally inserted into the locking groove 371 on the inner side of the mounting guide ring 37, and then slightly protrudes under the action of the spring to engage with the side wall of the locking groove 371. At this time, the locking pipe head 21 is rotated as a whole to realize the rotation of the locking pipe head 21, the sealing guide ring 22, the locking claw limit mounting seat 23 and the locking claw 24. In this embodiment, it is also necessary to state that the locking groove 371 is spirally arranged on the inner wall of the installation guide ring 37, and the depth of the locking groove 371 gradually deepens along the spiral direction, and the position where the outer wall of the installation guide locking tube head 36 contacts the lower locking protrusion 242 is gradually thinned in accordance with the depth change of the locking groove 371. In this way, as the locking tube head 21 rotates, the upper locking protrusion 241 and the lower locking protrusion 242 gradually protrude relative to each other under the guidance of the locking groove 371, and as this process progresses, the locking protrusion 241 and the lower locking protrusion 242 gradually protrude relative to each other. The spring rod between the locking claw 24 and the locking claw limit mounting seat 23 will be compressed, causing the locking claw 24 to move as a whole toward the inside of the installation guide ring 37 until the upper locking protrusion 241 protrudes upward under the action of the spring and is clamped into the second locking hole 3711 and the lower locking protrusion 242 protrudes downward under the action of the spring and is clamped into the first locking hole 364. At this time, the automatic locking between the locking tube head 21 and the installation guide locking tube head 36 is completed, so that the locking tube head 21 and the installation guide locking tube head 36 are clamped and will not fall off easily. , so far, the rapid installation and locking of the two pipes 1 are completed. In addition, the locking bolt 372 arranged on the outer side of the guide ring 37 corresponds to the position of the second locking hole 3711, and the upper locking boss 241 and the lower locking boss 242 are respectively fixed to the middle of the locking claw 24 by springs. The upper locking boss 241 and the lower locking boss 242 are respectively provided with a rack meshing with the pinion 243 on the side opposite to each other. The purpose of this design is to squeeze the locking bolt 372 on the locking by rotating the locking bolt 372 inward. The locking boss 241 causes the upper locking boss 241 to retract and disengage from the second locking hole 3711. At this time, with the cooperation of the rack and pinion 243, the lower locking boss 242 will also retract upward into the locking claw 24 to disengage from the first locking hole 364, completing the unlocking process, making it easier to pull out the locking pipe head 21. In addition, the locking bolt 372 can also protect the engagement state of the upper locking boss 241 and the locking groove 371 in the locked state, preventing external force from squeezing the upper locking boss 241 and causing the upper locking boss 241 to loosen.

[0021] Example 2 Please refer to Figures 1 to 20 On the basis of the first embodiment, this embodiment further proposes that eight groups of installation and correction pads 363 are symmetrically arranged inside and outside, the inner sides of the four outer groups of installation and correction pads 363 are movably installed with built-in locking limit blocks 3631, the outer surface of the sealing guide ring 22 is provided with a locking groove adapted to the built-in locking limit block 3631, the inner side of the outer round head sealing ring 362 is movably installed with a triangular small locking block 3621, the side walls of the four outer groups of installation and correction pads 363 are provided with movable grooves adapted to the triangular small locking block 3621, four groups of locking holes 364 are provided, and movable spring blocks 3641 are movably installed inside the four groups of locking holes 364 through springs, and the side walls of the outer round head sealing ring 362 are provided with movable grooves adapted to the movable spring blocks 3641; In this embodiment, as the sealing guide ring 22 is inserted into the installation guide groove 361, the initial installation state of the sealing guide ring 22 and the installation guide locking tube head 36 is completed. At this time, the movable spring block 3641 is above the round head sealing ring 362 under the action of the spring, and the triangular small locking block 3621 is retracted inside the round head sealing ring 362 under the pull of the small spring rod inside the triangular small locking block 362. The built-in locking limit block 3631 inside the installation correction pad 363 is in a telescopic state under the action of the elastic connector. As the locking tube head 21 is rotated and locked, the movable spring block 3641 is squeezed downward by the lower locking protrusion 242 and inserted into the round head sealing ring 362. The inside pushes the inner side of the triangular small locking block 3621, causing the triangular small locking block 3621 to flip outward and further squeeze the top of the built-in locking limit block 3631. At this time, the built-in locking limit block 3631 will be stuck in the groove of the sealing guide ring 22, completing the second locking effect, making the locking connection between the sealing guide ring 22 and the installation guide locking tube head 36 tighter. The same unlocking process is that the lower locking boss 242 contracts to cancel the pressure on the triangular small locking block 3621. At this time, the triangular small locking block 3621 and the built-in locking limit block 3631 are reset in turn, canceling the locking of the sealing guide ring 22.

[0022] Example 3 Please refer to Figures 1 to 20 On the basis of the second embodiment, this embodiment further proposes that a metal connection soft washer 351 is fixedly installed on one side of the floating self-locking pipe head 35 close to the connecting pipe head 31, a sealing bite ring 352 is fixedly installed on one side of the metal connection soft washer 351, the inner surface of the sealing bite ring 352 is fixedly connected to the outer wall of the connecting pipe head 31, a bite ring 32 is fixedly installed on one side of the connecting pipe head 31, a locking triangular ring 33 is fixedly installed on one side of the bite ring 32, and the locking triangular ring 33 is fixedly installed on the other side of the locking triangular ring 33. A center snap ring 34 is fixedly installed in the middle of one side. The bite ring 32, the locking triangle ring 33, and the center snap ring 34 are all arranged in the middle of the inner side of the floating self-locking tube head 35. A metal connection soft washer 2 354 is fixedly installed between the inner surface of the floating self-locking tube head 35 and the outer surface of the center snap ring 34. An inner sealing ring 353 is also symmetrically fixedly installed on the inner surface of the floating self-locking tube head 35. The outer surface of the bite ring 32 is provided with a limit adjustment groove adapted to the inner sealing ring 353. In this embodiment, the connecting pipe head 31, the bite ring 32, the locking triangle ring 33 and the center clamping ring 34 are connected as a whole. The floating self-locking pipe head 35 is fixed to the connecting pipe head 31 and the center clamping ring 34 respectively through the metal connecting soft washer 1 351, the sealing bite ring 352 and the metal connecting soft washer 2 354, and is wrapped around the outside of the bite ring 32, the locking triangle ring 33 and the center clamping ring 34. The sealing bite ring 352 mainly serves to increase the sealing between the floating self-locking pipe head 35 and the connecting pipe head 31, because the sealing bite ring 352, The shape and metal material of the metal connecting soft gasket 354 allow the floating self-locking tube head 35 to float slightly, and slight position adjustments can be made during the assembly process with the locking tube head 21, making it easier to align the sealing guide ring 22 and the installation guide locking tube head 36 for pre-installation. The inner sealing ring 353 mainly serves to seal the micro-floating adjustment gasket 355 and the limiting extrusion block 356 inside the floating self-locking tube head 35. At the same time, with the limiting cooperation of the inner sealing ring 353 and the bite ring 32, the adjustment range of the floating self-locking tube head 35 is limited.

[0023] Example 4 Please refer to Figures 1 to 20 On the basis of the third embodiment, this embodiment further proposes that the inner wall of the floating self-locking tube head 35 is symmetrically fixedly installed with a micro-floating adjustment washer 355, and the inner surfaces of the two groups of micro-floating adjustment washers 355 are respectively fixedly installed with a limited extrusion block 356, and eight groups of limited extrusion blocks 356 are provided. The middle part of the locking triangular ring 33 is symmetrically and movably installed with a locking triangular spring block 331, and the position of the locking triangular spring block 331 is adapted to the position of the limited extrusion block 356. The inner wall of the limited extrusion block 356 is provided with a card groove adapted to the locking triangular spring block 331, and the inner part of the center clamping ring 34 is movably installed with a pushing seat 341. The inner wall of the locking triangular ring 33 on one side close to the center clamping ring 34 is provided with a movable groove adapted to the pushing seat 341, and the inner side of the center clamping ring 34 on one side close to the installation guide groove 361 is provided with a movable groove adapted to the sealing guide ring 22; In this embodiment, the micro-floating adjustment washer 355 is fixed inside the floating self-locking tube head 35, and the limit extrusion block 356 is installed and supported by the elastic component. The side wall of the inner sealing ring 353 is provided with a movable groove adapted to the limit extrusion block 356. The limit extrusion block 356 elastically supports both sides of the locking triangle ring 33 with the cooperation of the micro-floating adjustment washer 355, and also plays a certain supporting role in the floating of the floating self-locking tube head 35. However, when the sealing guide ring 22 is installed in the guide groove 361 and the correction pad 363 is installed, the initial card is gradually completed with the installation guide locking tube head 36. When assembled and fixed, the front end of the sealing guide ring 22 will be inserted into the inner side of the center locking ring 34 to squeeze the push seat 341. At this time, the push seat 341 moves toward the side of the locking triangle ring 33, squeezing the middle part of the relatively set locking triangle spring block 331 to separate the locking triangle ring 33 and respectively snap into the inside of the limiting squeezing block 356 to complete the third locking. At the same time, the floating position of the floating self-locking pipe head 35 is also returned to its original position, so that the connecting pipe head 31, the floating self-locking pipe head 35, the installation guide locking pipe head 36, the sealing guide ring 22, and the locking pipe head 21 are assembled accurately, thereby improving the installation speed of the pipeline 1.

[0024] Example 5 Please refer to Figures 1 to 20 Based on the fourth embodiment, this embodiment further proposes a method for assembling a pipe with a quick connection assembly, comprising the following steps: Step 1: Pull the floating self-locking pipe head 35 to roughly align the sealing guide ring 22 with the installation guide groove 361, gradually advance the locking pipe head 21, and install the correction pad 363 to adjust the installation of the sealing guide ring 22 so that the sealing guide ring 22 is fully engaged with the installation guide groove 361. The round head sealing ring 362 will be engaged into the round head sealing groove 211, completing the preliminary installation between the locking pipe head 21 and the installation guide locking pipe head 36; Step 2: Then rotate the locking pipe head 21. The upper locking protrusion 241 and the lower locking protrusion 242 gradually protrude relative to each other under the guidance of the locking groove 371 until the upper locking protrusion 241 protrudes upward under the action of the spring and snaps into the second locking hole 3711, and the lower locking protrusion 242 protrudes downward under the action of the spring and snaps into the first locking hole 364. The automatic locking between the locking pipe head 21 and the installation guide locking pipe head 36 is completed, and the rapid installation of the two pipes 1 is completed; Step three, when unlocking is required, screw the locking bolt 372 inward so that the locking bolt 372 squeezes the upper locking boss 241 so that the upper locking boss 241 shrinks and disengages from the second locking hole 3711, and the lower locking boss 242 simultaneously shrinks upward into the locking claw 24 and disengages from the first locking hole 364, completing the unlocking process, and then pull out the locking pipe head 21 with force.
