Description

Technical Field

[0001] This invention relates to the field of pipe connector structure technology, specifically to a quick-assembly and disassembly pipe connector and its manufacturing equipment. Background Technology

[0002] In piping systems, pipe fittings are key components for connecting and securing pipes, and their performance directly affects the safety and stability of the entire piping system. During the manufacturing process of pipe fittings, clamping technology is a crucial step in ensuring the quality of the fittings and improving production efficiency.

[0003] While welding can provide high connection strength, its construction process is complex and requires a high level of technical skill from the operators. Furthermore, once the welding is completed, it is difficult to disassemble and replace, which undoubtedly increases the difficulty of later maintenance and modification.

[0004] While flange connections are easy to disassemble, they require precise bolt hole positioning and bolt tightening, making the process cumbersome. Furthermore, they demand high quality from both the flanges and bolts to prevent leaks. Threaded connections, on the other hand, are limited by pipe material and specifications. For non-standard or dissimilar pipes, they often fail to achieve ideal connection results and are susceptible to loosening or leaks due to environmental factors.

[0005] Furthermore, traditional connection methods are particularly inconvenient when dealing with emergency repairs or pipeline modifications, often requiring significant time and manpower for disassembly and reinstallation. This not only affects construction efficiency but also increases costs. Therefore, developing a pipe connector that can be quickly disassembled and assembled, has excellent sealing performance, and is suitable for various pipe specifications and materials has become an urgent technical challenge to be solved in the field of pipeline system engineering.

[0006] To address this, we propose a quick-assembly and disassembly pipe connector and its manufacturing equipment. Summary of the Invention

The guide sleeve is inserted into the spring cavity. The spring is sleeved on the outer surface of the guide sleeve and welded to the guide sleeve. The pipe connector is processed and tested by manufacturing equipment.

[0009] Preferably, a pipe release device is inserted into the end of the pipe insertion port. The pipe release device is divided into a fixed pipe release device and a variable diameter pipe release device. The fixed pipe release device consists of two semi-circular ring clamps that are hinged to each other. The variable diameter pipe release device consists of multiple arc-shaped clamps. Two adjacent arc-shaped clamps are fixed by inserting pins.

[0010] Among them, a quick-assembly and disassembly pipe connector and its manufacturing equipment include a machine body, in which a sealing detection unit and a conveying frame for pressure testing of the connection of the pipe connector are movable; A movable plate is slidably fitted on the body, an elastic plate is installed on the movable plate, a sleeve that is fitted with a pipe connector is rotatably connected to the elastic plate, a rotating plate is pressed against the elastic plate, and the middle part of the rotating plate is rotatably connected to the body. The machine body has a first clamping frame and a second clamping frame slidably fitted below the sleeve. The bottom of the first clamping frame and the second clamping frame are provided with clamping members. The clamping members bring the first clamping frame and the second clamping frame closer to each other to clamp the pipe connection inside the sleeve, so that the sealing detection unit can be lowered to perform a pressure test.

[0011] Preferably, a pressure rod is fixedly connected to the edge of the rotating plate, and a connecting plate that is rotatably connected to the pressure rod is rotatably connected to the movable plate.

[0012] Preferably, a support plate is fixedly connected to the outer surface of the sleeve, and an elastic rod is movably sleeved on the support plate and fixedly connected to the end of the elastic plate. A stabilizing rod is rotatably connected between the side of the end of the elastic plate and the sleeve.

[0013] Preferably, the sleeve consists of two semi-cylinders connected by a torsion spring rod, and magnetic plates that magnetically attract each other are installed at the other ends of the two semi-cylinders.

[0014] Preferably, a fixed plate is installed on the body, and a sliding groove is provided on the fixed plate to slide with the movable plate. The end cross-section of the movable plate is T-shaped, and the end cross-section of the sliding groove is "+" shaped.

[0015] Preferably, elastic elements are rotatably connected to both sides of the elastic plate, and the other end of the elastic element is rotatably connected to a fixed plate. A motor is fixedly connected to the fixed plate, and the output shaft of the motor is fixedly connected to the rotating plate.

[0016] Preferably, the clamping member includes a first connecting plate and a second connecting plate that are respectively connected and fixed to the first card frame and the second card frame. The first connecting plate is connected and fixed to the movable plate, and the second connecting plate is slidably engaged with the movable plate. A telescopic kit with an internal elastic element is fixedly connected between the first connecting plate and the second connecting plate. A telescopic rod that is engaged with the pressing rod is rotatably connected to the body. The bottom end of the telescopic rod is rotatably connected to the side of the second card frame.

[0017] Preferably, a base plate located above the telescopic assembly is fixedly connected to both the first connecting plate and the second connecting plate, and the movable plate is rotatably connected to the top end of the telescopic rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention's quick-connect pipe fitting, through its innovative structural design, enables rapid connection and disassembly of pipes. During connection, simply insert the pipe into the insertion port; the arc-shaped retaining ring, under the action of a spring, automatically engages with the outer surface of the pipe, forming a stable connection. During disassembly, simply release the retaining force of the arc-shaped retaining ring using a pipe release tool to easily pull out the pipe. This design greatly simplifies the operation process and improves construction efficiency, making it particularly suitable for emergency repairs and pipe modifications. The sealing cavity of this invention contains a high-performance seal; when positive or negative pressure is generated inside the pipe, the seal will not experience axial sliding or friction, effectively preventing fluid leakage. Simultaneously, the guide sleeve design ensures the accuracy and stability of pipe insertion, further improving sealing performance. This excellent sealing performance provides strong protection for the safe operation of the pipeline system.

[0019] The present invention provides a first clamping frame and a second clamping frame below the sleeve. The clamping components bring the two frames close together to clamp the pipe connector located inside the sleeve. This multi-clamping point design ensures the stability and accuracy of the connector during processing. The multi-clamping point design effectively disperses the clamping force, avoiding deformation or displacement of the connector due to uneven force, thus improving the quality of the final product. Moreover, the clamping structure design is flexible and can adapt to the processing needs of pipe connectors of different sizes and shapes.

[0020] This invention uses a motor to drive a rotating plate, which in turn moves an elastic plate and a sleeve, achieving automatic clamping of pipe fittings. This method eliminates the tedious process of manually adjusting the clamping force in traditional equipment, greatly improving production efficiency. Furthermore, the coordinated design of the elastic plate and the rotating plate enables precise control of the clamping force. The elastic plate undergoes elastic deformation under the pressure of the rotating plate, generating a stable clamping force and avoiding the problems of excessive or insufficient clamping force in traditional equipment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-19 The present invention provides a manufacturing equipment for quick-assembly and disassembly of pipe fittings, including a body 1, a sealing detection unit 2 for pressure testing of the connection of the pipe fittings and a conveying frame 3, which are movable inside the body 1; A movable plate 4 is slidably fitted on the machine body 1. An elastic plate 5 is installed on the movable plate 4. A sleeve 6, which is fitted onto the pipe connector, is rotatably connected to the elastic plate 5. A rotating plate 7 is press-fitted onto the elastic plate 5. The middle part of the rotating plate 7 is rotatably connected to the machine body 1. A first clamping frame 8 and a second clamping frame 9 are slidably fitted on the machine body 1, located below the sleeve 6. The bottom of the first clamping frame 8 and the second clamping frame 9 are provided with clamping components. The clamping components bring the first clamping frame 8 and the second clamping frame 9 close to each other to clamp the pipe connector located inside the sleeve 6, so that the sealing detection unit 2 can descend to conduct a pressure test. Through automated clamping and sealing detection, manual operation is reduced, and production efficiency is significantly improved. The multi-clamping point design also ensures the stability and accuracy of the pipe connector during processing, improves product quality, and can adapt to the processing needs of pipe connectors of different sizes and shapes, enhancing the flexibility and adaptability of the equipment.

[0025] The rotating plate 7 is fixedly connected to the edge of the rotating plate 7, and the movable plate 4 is rotatably connected to the connecting plate 11 which is rotatably connected to the pressing rod 10. Through the cooperation of the pressing rod 10 and the connecting plate 11, this application realizes precise control of the deformation of the elastic plate 5, thereby precisely controlling the clamping force. The design of the pressing rod 10 and the connecting plate 11 enables the rotational motion of the rotating plate 7 to be smoothly converted into the linear motion of the elastic plate 5, thus improving the stability of operation.

[0026] It is worth noting that: a support plate 12 is fixedly connected to the outer surface of the sleeve 6, and an elastic rod 13 is movably sleeved on the support plate 12 and fixedly connected to the end of the elastic plate 5. A stabilizing rod 14 is rotatably connected between the side of the end of the elastic plate 5 and the sleeve 6. The design of the support plate 12 and the elastic rod 13 enhances the connection stability between the sleeve 6 and the elastic plate 5, reduces vibration and offset, and the design of the stabilizing rod 14 ensures the stability of the elastic plate 5 during the deformation process, further improving the clamping accuracy.

[0027] The sleeve 6 consists of two semi-cylinders connected by a torsion spring rod. Magnetic plates 15 that magnetically attract each other are installed at the other ends of the two semi-cylinders. The split design of the sleeve 6 and the cooperation of the magnetic plates 15 make the clamping and removal of pipe fittings more convenient and faster.

[0028] The body 1 is equipped with a fixed plate 16, and the fixed plate 16 has a sliding groove 17 that slides with the movable plate 4. The end section of the movable plate 4 is T-shaped, and the end section of the sliding groove 17 is "+" shaped. The design of the T-shaped movable plate 4 and the "+" shaped sliding groove 17 improves the stability of the movable plate 4 during the sliding process. This structural design also enhances the connection strength between the movable plate 4 and the fixed plate 16, reducing the risk of deformation and damage.

[0029] Elastic elements 18 are rotatably connected to both sides of the elastic plate 5. The other end of the elastic element 18 is rotatably connected to the fixed plate 16. A motor 19 is fixedly connected to the fixed plate 16. The output shaft of the motor 19 is connected and fixed to the rotating plate 7. The motor 19 drives the rotating plate 7 to rotate, thereby driving the elastic plate 5 and the sleeve 6 to move, realizing the automation of the clamping process. The design of the elastic element 18 enables the elastic plate 5 to maintain a certain elasticity during the deformation process, further improving the operation accuracy and stability.

[0030] Regarding the clamping components, the clamping components include a first connecting plate 20 and a second connecting plate 21, which are respectively connected and fixed to the first clamping frame 8 and the second clamping frame 9. The first connecting plate 20 is connected and fixed to the movable plate 4, and the second connecting plate 21 is slidably engaged with the movable plate 4. A telescopic kit 22 with an internal elastic element is fixedly connected between the first connecting plate 20 and the second connecting plate 21. A telescopic rod 33 is rotatably connected to the body 1 and is engaged with the pressure rod 10. The bottom end of the telescopic rod 33 is rotatably connected to the side of the second clamping frame 9. The design of the telescopic kit 22 and the telescopic rod 33 allows the distance between the first clamping frame 8 and the second clamping frame 9 to be flexibly adjusted to accommodate pipe connectors of different sizes. The telescopic kit 22 with an internal elastic element further enhances the stability during the clamping process and reduces the risk of loosening and displacement.

[0031] The first connecting plate 20 and the second connecting plate 21 are both fixedly connected to a base plate 23 located above the telescopic kit 22. The movable plate 4 is rotatably connected to the top of the telescopic rod 33. The telescopic kit 22 with elastic elements inside further enhances the stability during the clamping process and reduces the risk of loosening and displacement. The rotatable connection between the movable plate 4 and the top of the telescopic rod 33 further optimizes the mechanical structure and improves the overall stability and durability of the equipment.

[0032] In this embodiment, the motor 19 causes the rotating plate 7 to rotate. On one hand, the rotating plate 7 presses against the elastic plate 5. On the other hand, the rotating plate 7 causes the movable plate 4 to move along the fixed plate 16 through the pressing rod 10 and the connecting plate 11, thereby causing the elastic plate 5 to move. That is, the elastic plate 5 rotates while being moved. When the arc-shaped section of the rotating plate 7 contacts the elastic plate 5, the part of the elastic plate 5 in contact with the rotating plate 7 is in a horizontal state, thereby causing the sleeve 6 to move downward at an angle. When the downward-sloping sleeve 6 drives the pipe connector to contact the bottom support plate 23, under continuous action and the action of the bottom support plate 23, the sleeve 6 and the pipe connector rotate to the same horizontal state as the bottom support plate 23, the elastic rod 13 bends, and the horizontal sleeve 6 and the pipe connector continue to approach the second clip frame 9. As the rotating plate 7 rotates, the second locking frame 9 moves away from the first locking frame 8, making it easier for the tilted pipe connector to move and contact the bottom support plate 23. Then, the second locking frame 9 moves closer to the first locking frame 8, cooperating with the horizontally moving pipe connector, so that the second locking frame 9 contacts the end of the pipe connector and drives the pipe connector to move, so that the other end of the pipe connector contacts the first locking frame 8, thereby completing the locking. The whole process changes the pipe connector from a state of being detached from the first locking frame 8 and the second locking frame 9 to a state where both ends of the pipe connector are in abutting contact with the first locking frame 8 and the second locking frame 9 respectively. It is worth noting that the movement trajectory of the end of the elastic plate 5 is as shown in the attached instruction manual. Figure 12 The middle dashed line.

[0033] The position of the first clip frame 8 remains unchanged. Under the action of the telescopic kit 22, the second clip frame 9 moves relative to the first clip frame 8. While the rotating plate 7 rotates, the pressing rod 10 presses against the telescopic rod 33, and the telescopic rod 33 extends and retracts, so that the second clip frame 9 moves away from the first clip frame 8 under the action of the telescopic kit 22. When the arc-shaped section of the rotating plate 7 contacts the elastic plate 5, the telescopic rod 33 rotates, driving the second clip frame 9 to move horizontally, so that the second clip frame 9 moves closer to the first clip frame 8, thus completing the installation of the pipe connector.

[0034] A quick-assembly and disassembly pipe connector includes a fixing mechanism and an integrally formed connecting mechanism. The connecting mechanism includes an axial limiting section 24, with a pipe cavity 25 fixedly connected to both ends of the axial limiting section 24. A sealing cavity 26 containing a sealing element is fixedly connected to the end of the pipe cavity 25, and a guide sleeve 27 is provided at the end of the sealing cavity 26. In this application, when positive or negative pressure is formed inside the pipeline, the seal will not slide or rub, thereby improving the sealing performance and service life of the seal and forming an independent sealed cavity. The function of the axial limiting joint 24 is to ensure that the insertion dimensions at both ends of the connecting mechanism are consistent when the pipe is inserted, and to ensure that the pipe and the sealing element have sufficient sealing contact surface. The function of the guide sleeve 27 is to extend outward from the sealing cavity 26 and form the guide sleeve 27. When the pipe is inserted, the pipe opening will not scratch the seal, forming a fixed sealing pressure, and preventing the inserted pipe from shaking radially. This ensures that the connecting mechanism and the pipe are on the same axis and precisely locks the toothed ring of the arc-shaped retaining ring 31 onto the pipe.

[0035] It is worth noting that the manufacturing process and technical requirements for the connecting mechanism are as follows: First, the semi-finished welded pipe is laser-cut to the specified size; Secondly, the internal high-pressure method is used for one-time molding, with no scratches or burrs on the inner and outer walls. The 26-seal cavity has high dimensional accuracy and can mold multiple workpieces at once, resulting in high efficiency, high pass rate, and greatly reduced production costs. Finally, stainless steel shot blasting improves surface corrosion resistance and extends product lifespan.

[0036] The fixing mechanism includes an arc-shaped sleeve 28 and a spring cavity 29 that are connected and fixed to each other. A pipe insertion port 30 is fixedly connected to the end of the arc-shaped sleeve 28. An arc-shaped retaining ring 31 is sleeved inside the arc-shaped sleeve 28. The arc-shaped retaining ring 31 presses against a spring 32 located inside the spring cavity 29. A guide sleeve 27 is inserted into the spring cavity 29. The spring 32 is sleeved on the outer surface of the guide sleeve 27 and welded to the guide sleeve 27. The function of the arc-shaped sleeve 28 in this application is as follows: when the toothed ring of the arc-shaped retaining ring 31 slides outward, the diameter of the arc-shaped retaining ring 31 shrinks until the tooth tip is in close contact with the inserted pipe and forms a certain engagement with the outer surface of the inserted pipe, so that the pipe will not move axially, thereby achieving the effect of complete edge connection. The arc-shaped retaining ring 31 is formed in one step. Furthermore, the back of the arc-shaped retaining ring 31 adopts a multi-arc design to reduce the friction between the arc-shaped retaining ring 31 and the outer ring of the fixing mechanism, so that the arc-shaped retaining ring 31 always adheres to the outer surface of the inserted pipe, ensuring that the installed pipe is 100% locked. The back of the arc-shaped retaining ring 31 is designed at a 7-degree angle to the retaining teeth. The curvature of the tooth tips of the arc-shaped retaining ring 31 is consistent with the inserted pipe. Each retaining tooth of the arc-shaped retaining ring 31 is aligned with the surface of the pipe, which greatly increases the friction with the pipe. The arc-shaped retaining ring 31 is designed so that when there is pressure in the pipe, the pipe has a radial pull force. The greater the pull force, the greater the pull force of the arc-shaped retaining ring 31. The axial direction of the back of the arc-shaped retaining ring 31 is also larger. The arc-shaped retaining ring 31 design increases the force-bearing area, making the outer ring of the fixing mechanism less prone to deformation. The arc-shaped retaining ring 31 adopts a C-mouth design to overcome the diameter tolerance during pipe manufacturing; The pipe insertion end of the arc-shaped sleeve 28 is equipped with a waterproof sealing sleeve. After the pipe is inserted and connected, it is sealed by the waterproof sealing sleeve to prevent rainwater and splashing water from entering the connection mechanism and extend the service life of the outlet ring and spring 32. An arc-shaped retaining ring 31 is installed inside the fixing mechanism, and the spring 32 is assembled and welded with the sealing mechanism to make it a whole workpiece. Among them, the welded joint has an inward arc chamfer to match the shape of the sealing cavity 26 of the sealing mechanism, increasing the contact surface of the weld. Through laser welding, the inner surface of the sealing cavity 26 is protected from oxidation and deformation, ensuring that the sealing cavity 26 is effectively sealed.

[0037] It is worth noting that: in order to further improve the flexibility and convenience of pipe connection, a pipe release device is inserted into the end of the pipe insertion port 30. The pipe release device is divided into a fixed pipe release device 34 and a variable diameter pipe release device 35. The fixed pipe release device 34 is composed of two semi-circular ring clamps that are hinged to each other and is suitable for pipe connection of specific specifications. The variable diameter pipe disconnector 35 consists of multiple arc-shaped retaining rings. Two adjacent arc-shaped retaining rings are fixed by inserting pins, which can be flexibly adjusted according to the pipe diameter to meet the connection requirements of pipes of different specifications.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
