Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a novel pipe fitting joint. Background Technology

[0002] The research and application of new pipe fittings closely meet the stringent requirements of modern engineering. In many special environments, such as high temperature, low temperature, high pressure, and high corrosion scenarios, as well as areas with extreme conditions such as deep-sea engineering and the Pingtan Strait, higher standards are set for the performance of pipe fittings to ensure the stable operation of pipelines.

[0003] The existing technology of new pipe fittings is developing in a diversified manner, covering a variety of types to meet different working conditions. The clamp-type flexible joint consists of a high-strength metal clamp, a rubber sealing ring and a pre-processed grooved pipe interface. The sealing ring is compressed and deformed by bolt tightening to achieve sealing. It can compensate for the axial expansion and lateral displacement of the pipeline and has the advantages of welding-free and modular installation.

[0004] Traditional pipe fittings cannot adapt to pipes of different diameters, which not only limits the flexibility of the pipeline, but also requires the use of multiple types of fittings to connect pipes of different specifications, increasing the cost of spare parts procurement and inventory pressure, but also prolongs the construction time and reduces installation efficiency due to frequent replacement of fittings. Therefore, a new type of pipe fitting is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a new type of pipe fitting, which aims to improve the problem that existing pipe fittings cannot adapt to pipes of different diameters. This not only limits the flexibility of the pipes, requiring multiple types of fittings to be used for connecting pipes of different specifications, increasing the cost of parts procurement and inventory pressure, but also prolongs construction time and reduces installation efficiency due to frequent replacement of fittings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel pipe fitting includes a pipe, wherein a fixed installation mechanism is movably connected to the outside of the pipe, and a quick-connect mechanism is movably connected to the outside of the pipe.

[0008] The fixed installation mechanism includes two rotating rings, both of which are rotatably connected to the outside of the pipe. A sliding rod is fixedly connected to the outside of each rotating ring, and a mounting shaft is slidably connected to the outside of each sliding rod. A spring is installed on the outside of each sliding rod, and a fixing component is rotatably connected to the outside of each rotating ring.

[0009] As a further description of the above technical solution:

[0010] The quick docking mechanism includes a second connector, which is internally movably connected to the outside of the pipe. A first connector is movably connected to the outside of the second connector. Two mounting plates are fixedly connected to the outside of the second connector. A fixed shaft is fixedly connected inside each of the two mounting plates. A rotating shaft is rotatably connected to the outside of each of the two fixed shafts. A cam is fixedly connected to the outside of each of the two rotating shafts. An operating block is fixedly connected to the outside of each rotating shaft. Two grooves are formed on the outside of the first connector.

[0011] As a further description of the above technical solution:

[0012] The fixing assembly includes three rotating plates, all of which are rotatably connected to the outside of the rotating ring, and all of which are fixedly connected to a locking block.

[0013] As a further description of the above technical solution:

[0014] The exterior of both rotating shafts is slidably connected to the interior of both grooves, and the interior of both cams is rotatably connected to the exterior of both fixed shafts;

[0015] As a further description of the above technical solution:

[0016] One of the mounting shafts is externally fixedly connected to the inside of the first joint, and the other mounting shaft is externally fixedly connected to the inside of the second joint;

[0017] As a further description of the above technical solution:

[0018] One of the sliding rods is externally slidably connected to the inside of the first joint, and the other sliding rod is externally slidably connected to the inside of the second joint;

[0019] As a further description of the above technical solution:

[0020] The outer end of the rotating ring is rotatably connected to the inside of the mounting shaft, and the other end of the spring is fixedly connected to the inside of the mounting shaft;

[0021] As a further description of the above technical solution:

[0022] The three rotating plates are fixedly connected to the outside of the mounting shaft, and the three locking blocks are movably connected to the outside of the pipe.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sliding rod and the spring work together to generate the force of the spring after compression and rebound, which drives the sliding rod to slide in the opposite direction, thereby causing the rotating ring to rotate. This causes the rotating plate to drive the locking block to rotate as well, ultimately allowing the locking block to make tight contact with the outside of the pipe, thus achieving rapid fixed installation of the pipe and the two joints. The entire process relies on the linkage of various structures, which simplifies the installation operation and ensures the stability of the connection after installation by using the locking block to stably clamp the pipe.

[0025] 2. In this utility model, the outer side of the sliding joint cooperates with the inner side of another joint. The groove on the joint guides the rotating shaft on the other joint into the corresponding position. Then, the rotating joint makes the groove and the rotating shaft misaligned. Subsequently, the operating block drives the cam on the outside of the rotating shaft to rotate, so that the cam locks with the groove on the outside of the joint. This achieves close linkage of the various structures, thereby quickly completing the pipe connection. Moreover, the components cooperate precisely during the connection process, which can ensure the stability and reliability of the connection. Attached Figure Description

[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 to 3 This utility model provides an embodiment of a novel pipe fitting joint, including a pipe 1, which is the core carrier of the entire joint connection and is used to transport fluids and other media. The pipe 1 is externally connected to a fixed installation mechanism 2, which can stably fix the pipe 1 in a designated position to ensure the stability of the connection. The pipe 1 is externally connected to a quick-connect mechanism 3, which can realize the quick and convenient connection of the pipe 1 with other pipe fittings, improving installation efficiency. The fixed installation mechanism 2 includes two rotating rings 23, which are important rotating components of the fixed installation mechanism 2. Their rotation can drive the operation of subsequent components.

[0034] Both rotating rings 23 are rotatably connected to the outside of the pipe 1. This rotatable connection allows the rotating rings 23 to rotate flexibly around the pipe 1, providing a basis for subsequent fixing actions. A sliding rod 22 is fixedly connected to the outside of the rotating rings 23. The sliding of the sliding rod 22 can directly drive the rotating rings 23 to rotate. A mounting shaft 21 is slidably connected to the outside of the sliding rod 22. The mounting shaft 21 provides a stable track for the sliding of the sliding rod 22, ensuring that the sliding rod 22 moves in a predetermined direction. A spring 24 is installed on the outside of the sliding rod 22. The elastic force of the spring 24 is the key to the reset of the sliding rod 22 and can drive the sliding rod 22 to move through extension and retraction.

[0035] The rotating ring 23 is externally connected to a fixing component 25. The fixing component 25 is the direct actuator for fixing the pipe 1. The fixing component 25 includes three rotating plates 251. Each of the three rotating plates 251 is externally fixedly connected to a locking block 252. The three rotating plates 251 can change their own angle by rotating, thereby driving the locking block 252 to move. The three rotating plates 251 are externally rotatably connected to the outside of the rotating ring 23. This connection method allows the rotating plates 251 to rotate synchronously with the rotating ring 23. The locking block 252 can contact and lock the pipe 1, thereby firmly fixing the pipe 1.

[0036] Reference Figure 1 , Figure 2 and Figure 4The quick docking mechanism 3 includes connector 2 32, which is externally movably connected to connector 1 31. The quick docking mechanism 3 is the core component for realizing the quick docking of pipe 1. Connector 2 32, as its key component, provides the basic installation structure for docking with connector 1 31. The internal movable connection of connector 2 32 is external to pipe 1. This movable connection method facilitates the initial placement of pipe 1 into the docking position and reserves operating space for subsequent fixation of pipe 1 and connector 2 32 through the installation shaft 21 and related structures. The movable connection between the two allows connector 1 31 to slide and rotate relative to connector 2 32, which is a prerequisite for realizing the quick docking of pipe 1 and facilitates the subsequent sliding of connector 1 31 into the interior of connector 2 32 and completion of positioning.

[0037] The external fixed connection of connector 2 32 consists of two mounting plates 33. Each mounting plate 33 has a fixed shaft 34 fixedly connected internally. Each fixed shaft 34 has a rotating shaft 35 rotatably connected externally. Each rotating shaft 35 has a cam 36 fixedly connected externally. Each rotating shaft 35 has an operating block 37 fixedly connected externally. The two mounting plates 33 provide a stable mounting carrier for components such as the fixed shaft 34 and rotating shaft 35, ensuring structural stability during docking operations and guaranteeing precise execution of the locking action. The fixed shaft 34 is fixed within the mounting plate 33, serving as the rotation fulcrum for the rotating shaft 35 and the cam 36, making the rotation trajectory of the cam 36 controllable and providing a structural basis for the subsequent clamping of connector 1 31 by the cam 36. The rotating shaft 35 can rotate around the fixed shaft 34. This design allows the rotating shaft 35 to adjust its position with the movement of the operating block 37, facilitating its entry into the corresponding position through the slot of connector 1 31, preparing for docking and locking.

[0038] Cam 36 is fixed on rotating shaft 35. When rotating shaft 35 rotates, cam 36 can rotate accordingly. Its special profile can lock the slot on the outside of connector 1 31 after rotation, thereby achieving a tight lock between connector 1 31 and connector 2 32. Operating block 37 provides a convenient point of force for the operator. By rotating operating block 37, the rotating shaft 35 and cam 36 can be directly driven to move, simplifying the docking and locking operation steps and improving docking efficiency. Two grooves 38 are opened on the outside of connector 1 31. The two grooves 38 match the rotating shaft 35 on connector 2 32, providing space for the insertion of rotating shaft 35 and the locking of cam 36, ensuring that connector 1 31 and connector 2 32 can be accurately positioned during docking.

[0039] Both rotating shafts 35 are slidably connected to the outside of the two grooves 38. This slidable connection allows the rotating shafts 35 to smoothly enter the slots outside the connector 31 when the connector 1 31 slides into the connector 2 32. This creates conditions for subsequent adjustment of the position of the connector 1 31 and locking it through the cams 36. Both cams 36 are rotatably connected to the outside of the two fixed shafts 34. The cams 36 rotate around the fixed shafts 34. The fixed support of the fixed shafts 34 ensures that the cams 36 can accurately engage with the slots outside the connector 1 31 when rotating, ensuring a stable and reliable locking effect. One mounting shaft 21 is fixedly connected to the inside of the connector 1 31. This mounting shaft 21 provides an installation base for the sliding rod 22, rotating ring 23 and other fixed components inside the connector 1 31, ensuring that the pipe 1 can be stably connected to the connector 1 31. The other mounting shaft 21 is fixedly connected to the inside of the connector 2 32. This mounting shaft 21 cooperates with the mounting shaft 21 inside the connector 1 31 to provide support for the fixed structure of the pipe 1, ensuring that the pipe 1 can be stably installed with both the connector 1 31 and the connector 2 32.

[0040] Reference Figures 2 to 4 One sliding rod 22 is externally slidably connected to the inside of joint 1 31. This connection method allows the sliding rod 22 to move flexibly within joint 1 31, providing a basis for subsequently driving the spring 24 to compress or rebound. The other sliding rod 22 is externally slidably connected to the inside of joint 2 32, which also ensures the smooth sliding of the sliding rod 22 within joint 2 32. Together with the former, they participate in the installation and fixing process of pipe 1.

[0041] The rotating ring 23 is externally rotatably connected to the inside of the mounting shaft 21. This connection allows the rotating ring 23 to rotate around the mounting shaft 21, thereby transmitting power under the drive of the sliding rod 22. The other end of the spring 24 is fixedly connected to the inside of the mounting shaft 21. The fixed connection ensures that the spring 24 can accumulate elastic potential energy and rebound smoothly after being compressed by the sliding rod 22, providing power for the reverse sliding of the sliding rod 22. The three rotating plates 251 are externally fixedly connected to the outside of the mounting shaft 21, so that the rotation of the mounting shaft 21 can directly drive the rotating plates 251 to rotate synchronously, realizing the effective transmission of power. The three locking blocks 252 are all externally movably connected to the outside of the pipe 1. The movable connection ensures that the locking blocks 252 can rotate under the drive of the rotating plates 251 and contact the pipe 1, thereby firmly fixing the pipe 1.

[0042] Working principle: When it is necessary to fix and install pipe 1 with connector 31 and connector 32, the two sliding rods 22 are slidable. Under the sliding of the two sliding rods 22, the two springs 24 are compressed. Then pipe 1 is inserted. At this time, the two sliding rods 22 are released. Due to the pressure, the two springs 24 rebound. Under the rebound of the two springs 24, the two sliding rods 22 slide in opposite directions. Under the sliding of the two sliding rods 22, the two rotating rings 23 rotate. Under the rotation of the two rotating rings 23, multiple rotating plates 251 rotate. Under the rotation of the multiple rotating plates 251, multiple locking blocks 252 rotate. When the outside of the multiple locking blocks 252 rotates to contact the outside of pipe 1, the springs 24 stop rebounding, and the installation of pipe 1 with connector 31 and connector 32 is completed.

[0043] When quick connection of pipe 1 is required, the outer part of the sliding joint 31 is slid into the inner part of the joint 32 through the sliding joint 31. When the outer part of the joint 31 contacts the inner part of the joint 32, the two rotating shafts 35 on the joint 32 enter the slots on the outer part of the joint 31 through the two grooves 38 on the joint 31. Then the joint 31 is rotated. When the two grooves 38 on the joint 31 rotate away from the two rotating shafts 35, the two operating blocks 37 are rotated downward. When the two operating blocks 37 rotate, they drive the cams 36 on the outer part of the two rotating shafts 35 to rotate, so that the two cams 36 lock into the slots on the outer part of the joint 31, thus completing the connection of pipe 1.

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.
