Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a connector. Background Technology

[0002] In the field of pipeline engineering, stable pipeline connection is the core link to ensure the efficient and safe operation of fluid (liquid or gas) transportation system. At present, most of the existing precision pipeline connection methods adopt unidirectional external fixing structure, such as connecting by means of flange and bolt fastening, clamping on one side, etc.

[0003] This unidirectional external fixed connection method has obvious limitations in actual installation and use. Since the fixing points are only distributed on one side or in one direction of the pipe connection, when the pipe is subjected to axial thrust, radial tension or external environmental vibration, the connection part is prone to relative displacement due to uneven force, which leads to misalignment. This misalignment problem is more prominent in scenarios such as long-distance pipeline laying, large fluctuations in fluid transport pressure, or continuous vibration in the installation environment.

[0004] Misaligned connections not only reduce the sealing performance of pipe connections, causing fluid leaks, increasing maintenance costs and safety hazards, but may also cause connecting components (such as bolts, clamps, etc.) to wear faster and fracture due to concentrated stress. In severe cases, it may even affect the normal operation of the entire pipeline system, bringing adverse effects to industrial production, municipal construction and other fields.

[0005] In addition, traditional unidirectional fixed structures require high installation accuracy during assembly. If there is a slight deviation during the initial installation, the degree of misalignment can be amplified due to stress accumulation during subsequent use, further reducing the reliability of the connection. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A connector, comprising:

[0008] Fixed frame: Its surface is symmetrically and in reverse order from the inside to the outside with double-coil tube seats and single-coil tube seats;

[0009] Drive tube seat: It is located between the two sets of double-disc tube seats and is rotatably connected to the inner wall of the two sets of double-disc tube seats. The surface of the drive tube seat is symmetrically provided with first elastic clips, which are engaged and fixed with the clip holes on the inner flange surface of the two sets of double-disc tube seats through the first elastic clips. A drive shaft is fixedly connected to the inner wall of the drive tube seat. Both ends of the drive shaft pass through to the outside of the two sets of double-disc tube seats, and its through ends are provided with threaded parts and eccentric fixing blocks from the inside to the outside.

[0010] Fixed tube seat: Symmetrically arranged in opposite directions between the double-disc tube seat and the single-disc tube seat, and coaxially sleeved on the outside of the through end of the transmission shaft. The inner wall of the fixed tube seat is threaded to the threaded part and is horizontally slidably connected to the inner walls of the double-disc tube seat and the single-disc tube seat. An eccentric positioning ring seat is fixedly connected to the inner wall of the fixed tube seat at the position corresponding to the eccentric fixing block. Fixed shafts are uniformly fixedly connected to the flange surface of the fixed tube seat. One end of the fixed shaft is horizontally slidably connected to the inner wall of the outer flange of the double-disc tube seat, and the other end passes through the inner wall of the flange of the single-disc tube seat. A second elastic clip is uniformly provided at its through end.

[0011] As a further embodiment of this utility model, it also includes a left pipe and a right pipe, which are respectively located outside the two sets of single-disc pipe seats and arranged in opposite directions. The flanges of the left pipe and the right pipe are respectively in contact with the flange surfaces of the two sets of single-disc pipe seats, and both flanges are sleeved on the outside of the corresponding side fixed shaft and in contact with the surface of the second elastic clip. The flange surfaces of the left pipe and the right pipe are each provided with an insertion section. One end of the insertion section is horizontally slidably connected to the inner wall of the fixed pipe seat and sleeved on the outside of the eccentric fixed block and the eccentric positioning ring seat.

[0012] As a further embodiment of this utility model: a fixed ring frame is provided at the connection between the inner wall of the drive tube seat and the transmission shaft, and a threaded ring frame is provided at the connection between the fixed tube seat and the threaded part, and the threaded ring frame is located inside the eccentric positioning ring seat, and through grooves are provided on the surfaces of both the fixed ring frame and the threaded ring frame.

[0013] As a further embodiment of this utility model: elastic sealing rings are provided at the connection between the drive tube seat and the inner wall of the double-disc tube seat, the connection between the fixed tube seat and the inner wall of the double-disc tube seat and the inner wall of the single-disc tube seat, and the connection between the threaded ring frame and the surface of the transmission shaft.

[0014] As a further embodiment of this utility model: a rubber sealing gasket is provided between the flange of the left pipe and the right pipe and the flange of the corresponding single-disc pipe seat, and the rubber sealing gasket is sleeved on the outside of the fixed shaft.

[0015] As a further embodiment of this utility model: the surface of the drive tube seat is uniformly provided with weight reduction grooves, and each of the two sets of clamping holes on the inner flange surface of the double-disc tube seat is provided with two sets, and the included angle between the two clamping holes in the same set is 180°.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Solve the problem of connection misalignment and improve connection stability: Compared with the existing one-way external fixing method, which is prone to misalignment due to uneven force, this utility model achieves bidirectional fixing through the dual positioning structure of "internal fixing + external fixing". The external fixing pushes the pipe flange and the single-disc pipe seat to fit together through the second elastic clip of the fixing shaft, and the internal fixing abuts against the inner wall of the pipe insertion section after the eccentric fixing block rotates. The bidirectional synergistic effect can effectively offset the influence of axial and radial forces and vibration, and significantly reduce connection misalignment.

[0018] 2. Enhance sealing performance and reduce leakage risk: Elastic sealing rings are installed at key connections such as drive pipe seat and double disc pipe seat, fixed pipe seat and disc pipe seat, threaded ring bracket and drive shaft, and rubber sealing gaskets are added between pipe flange and single disc pipe seat. The multi-seal structure greatly improves the sealing performance of the connection, which can effectively prevent fluid leakage and reduce maintenance costs and safety hazards.

[0019] 3. Simplify the installation process and reduce precision requirements: The internal and external fixing actions can be completed simultaneously by rotating the drive tube seat, without the need for step-by-step operation; and the structural design allows for a certain installation error. Even if there are slight deviations in the initial assembly, they can be compensated for by the sliding fit and elastic snap-fit ​​between the components, reducing connection failures caused by precision issues.

[0020] 4. Optimized structural design, balancing lightweight and reliability: Weight-reducing grooves are opened on the surface of the drive tube seat to reduce the overall weight while ensuring structural strength; the double-coil tube seat and the single-coil tube seat are symmetrically arranged in opposite directions, and the circumferential distribution of the fixed shaft makes the force more balanced and extends the service life of the components; the through groove design of the fixed ring frame and the threaded ring frame does not affect the fluid transport, while enhancing the stability of the connection parts.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figure 1-5 One connector in this embodiment of the present utility model includes:

[0031] Fixed frame 1: Its surface is symmetrically and in reverse order from the inside to the outside with double coil seat 11 and single coil seat 12 fixedly connected;

[0032] Drive tube seat 2: It is located between two sets of double-disc tube seats 11 and is rotatably connected to the inner wall of the two sets of double-disc tube seats 11. The surface of the drive tube seat 2 is symmetrically provided with first elastic clips 21, and is fixed by the first elastic clips 21 to the clip holes 111 on the surface of the inner flange of the two sets of double-disc tube seats 11. The inner wall of the drive tube seat 2 is fixedly connected with a transmission shaft 22. Both ends of the transmission shaft 22 pass through to the outside of the two sets of double-disc tube seats 11, and its through end is provided with a threaded part 23 and an eccentric fixing block 24 from the inside to the outside.

[0033] Fixed tube seat 3: Symmetrically and oppositely arranged between double-disc tube seat 11 and single-disc tube seat 12, and coaxially sleeved on the outside of the through end of the transmission shaft 22. The inner wall of the fixed tube seat 3 is threaded to the threaded part 23 and is horizontally slidably connected to the inner walls of the double-disc tube seat 11 and the single-disc tube seat 12. An eccentric positioning ring seat 31 is fixedly connected to the inner wall of the fixed tube seat 3 at the position corresponding to the eccentric fixing block 24. Fixed shafts 32 are uniformly fixedly connected to the flange surface of the fixed tube seat 3. One end of the fixed shaft 32 is horizontally slidably connected to the inner wall of the outer flange of the double-disc tube seat 11, and the other end passes through the inner wall of the flange of the single-disc tube seat 12. A second elastic clip 33 is uniformly provided at its through end.

[0034] It should be noted that the two sets of threaded portions 23 described in this embodiment have opposite thread directions.

[0035] Specifically, this utility model solves the problem of easy misalignment in traditional unidirectional fixing by using internal and external fixing for dual positioning, improves connection stability, enhances sealing performance through multiple sealing structures, reduces leakage risk, simplifies installation process, reduces precision requirements, adapts to errors, and features a lightweight design that balances strength and reliability, thus extending service life.

[0036] The three core components—fixed frame 1, drive pipe seat 2, and fixed pipe seat 3—constitute the main framework of the connector. Through coordinated operation, they achieve bidirectional pipe fixation. The fixed frame 1 serves as the base of the entire connector, providing an installation carrier for the drive pipe seat 2 and fixed pipe seat 3. Rigid fixation ensures the positional accuracy of each component. The double-disc pipe seat 11 is located on the inner side, providing space for the rotation of the drive pipe seat 2, while the single-disc pipe seat 12 is located on the outer side, providing a reference for the fitting of the pipe flange. This layout ensures complete symmetry between the left and right sides, laying the foundation for bidirectional synchronous fixation and avoiding overall displacement caused by unilateral force. Positioned between the two sets of double-coil tube seats 11, the drive tube seat 2 can rotate relative to its inner wall and serves as the power source for the entire structure. Symmetrically distributed first elastic locking members 21 engage with the locking holes 111 of the inner flange of the double-coil tube seat 11, achieving positioning and locking after the drive tube seat 2 rotates. This prevents accidental rotation during non-operational switching, such as from unfixed to fixed states. The drive shaft 22 is fixedly connected to the inner wall of the drive tube seat 2, transmitting rotational motion to the threaded portions 23 and eccentric fixing blocks 24 at both ends, acting as a bridge for power transmission. The eccentric fixing blocks 24 rotate with the drive shaft 22 and can subsequently cooperate with the pipe insertion section 6 to achieve radial clamping, thus performing the internal fixing action. The core actuator, the fixed pipe seat 3, is symmetrically and oppositely distributed between the double-disc pipe seat 11 and the single-disc pipe seat 12, and is sleeved on the outside of the drive shaft 22. It is the actuator that connects the drive pipe seat 2 and the pipe. The threaded part 23 rotates with the drive shaft 22. When the drive shaft 22 rotates, the threaded parts 23 on both sides, due to their opposite directions, drive the left and right fixed pipe seats 3 to move inward synchronously, providing power for external fixation. The eccentric positioning ring seat 31 corresponds to the eccentric fixing block 24. The eccentric fixing block 24 rotates with the drive shaft 22, and finally cooperates with the eccentric positioning ring seat 31 to clamp the pipe insertion section 6, completing the internal fixation. The fixed shaft 32 rotates with the drive shaft 22. The fixed pipe seat 3 slides, and the second elastic clip 33 at its end pushes the pipe flange to fit against the single-disc pipe seat 12, achieving axial clamping and external fixation. At the same time, the sliding connection between the fixed shaft 32 and the double-disc pipe seat 11 and the single-disc pipe seat 12 ensures that the sliding process is stable and does not deviate. These three components provide a reference through the fixed frame 1 → drive the pipe seat 2 to input power → the fixed pipe seat 3 to perform the action. With the reverse thread design, a two-way fixation of internal clamping and external clamping of the pipe is achieved. The structure solves the problem of easy misalignment of traditional unidirectional fixation. At the same time, the symmetrical layout ensures balanced force and improves the stability and reliability of the connection.

[0037] Further as Figure 1As shown, it also includes a left pipe 4 and a right pipe 5. The left pipe 4 and the right pipe 5 are respectively located outside the two sets of single-disc pipe seats 12 and arranged in opposite directions. The flanges of the left pipe 4 and the right pipe 5 are respectively in contact with the flange surfaces of the two sets of single-disc pipe seats 12. Both flanges are sleeved on the outside of the corresponding side fixed shaft 32 and in contact with the surface of the second elastic clip 33. The flange surfaces of the left pipe 4 and the right pipe 5 are each provided with an insertion section 6. One end of the insertion section 6 is horizontally slidably connected to the inner wall of the fixed pipe seat 3 and is sleeved on the outside of the eccentric fixed block 24 and the eccentric positioning ring seat 31.

[0038] Specifically, the left pipe 4 and right pipe 5 are located outside the two sets of single-disc pipe seats 12, arranged in opposite directions, perfectly matching the symmetrical structure of the double-disc pipe seats 11 and single-disc pipe seats 12 on the fixed frame 1. This layout ensures that the pipes on the left and right sides are subjected to balanced forces, avoiding connection misalignment caused by unilateral load, and is also suitable for bidirectional fluid transport scenarios, such as bidirectional flow scenarios in industrial pipeline systems. The pipe flange abuts against the flange surface of the corresponding single-disc pipe seat 12, forming an external reference surface for connection, providing a basis for subsequent sealing and fixing. The pipe flange is sleeved on the outside of the fixed shaft 32. The fixed shaft 32, through the guiding action of penetrating the flange, restricts the circumferential rotation and radial offset of the pipe, ensuring the coaxiality of the pipe and the connector. The flange abuts against the surface of the second elastic clamp 33. When the fixed pipe seat 3 drives the fixed shaft 32 to slide inward, the second elastic clamp 33 will push the pipe flange to move towards the single-disc pipe seat 12. Ultimately, the two are tightly fitted together by the rubber sealing gasket 7, achieving external axial pressure locking of the pipe. The insertion section 6 is the key structure for internal pipe fixation, forming a precise fit with the eccentric component of the connector. One end of the insertion section 6 is inserted into the inner wall of the fixed pipe seat 3 and can slide horizontally along the inner wall, providing guidance for the relative movement of the pipe and the fixed pipe seat 3, ensuring that the pipe does not tilt during the fixing process. The insertion section 6 is sleeved on the outside of the eccentric fixing block 24 and the eccentric positioning ring seat 31. When the drive pipe seat 2 rotates and drives the transmission shaft 22 to rotate, the eccentric fixing block 24 rotates synchronously and abuts against the inner wall of the insertion section 6, forming a radial clamping of the insertion section 6 with the eccentric positioning ring seat 31, achieving internal pipe fixation and preventing axial movement or radial misalignment of the pipe. External fixation ensures a sealed fit between the pipe and the single-disc pipe seat 12 through axial thrust; internal fixation restricts the displacement of the pipe through radial clamping. The two work together to solve the problem of easy misalignment in traditional unidirectional fixation.

[0039] Further as Figures 3-4 As shown, a fixed ring 20 is provided at the connection between the inner wall of the drive tube seat 2 and the transmission shaft 22, and a threaded ring 30 is provided at the connection between the fixed tube seat 3 and the threaded part 23. The threaded ring 30 is located inside the eccentric positioning ring seat 31, and through grooves are provided on the surfaces of both the fixed ring 20 and the threaded ring 30.

[0040] Specifically, the drive tube seat 2 rotates to drive the transmission shaft 22 synchronously. The connection point needs to continuously withstand torque. The fixed ring 20 uses a ring structure to evenly distribute the driving force to the inner wall of the drive tube seat 2 and the surface of the transmission shaft 22, avoiding connection loosening or breakage caused by local stress concentration, and ensuring lossless power transmission. The through groove on the surface does not hinder the internal space layout of the drive tube seat 2, and can reduce its own weight. At the same time, it allows fluid pipe connections or media to pass through, balancing structural strength and functionality. The fixed tube seat 3 achieves horizontal sliding through engagement with the threaded part 23. The threaded mating part needs to withstand axial thrust and rotational friction. The threaded ring 30, as a ring reinforcement embedded in the inner wall of the fixed tube seat 3, can disperse the stress during thread engagement, prevent the inner wall of the fixed tube seat 3 from failing due to long-term wear or deformation, and extend the mating life. Its layout inside the eccentric positioning ring seat 31 avoids contact with the eccentric positioning ring. The structural interference between seat 31 and pipe insertion section 6 ensures smooth internal fixing of the pipe by eccentric fixing block 24 and eccentric positioning ring seat 31. The surface groove design is consistent with that of fixing ring frame 20, which can adapt to fluid flow requirements, while reducing overall weight and avoiding unnecessary load. Although the fixing ring frame 20 and threaded ring frame 30 are in different positions, they form a reinforced system of "power transmission link": the fixing ring frame 20 ensures stable torque transmission of the "power input end" driving pipe seat 2 → transmission shaft 22, which is the basis for effective transmission of rotational power; the threaded ring frame 30 ensures reliable threaded transmission of the "power execution end" transmission shaft 22 → fixing pipe seat 3, which is the key guarantee for the conversion of rotational motion into linear sliding. Through the ring structure reinforcement and groove design, the two not only improve the structural strength of key parts, but also adapt to the functional requirements of the connectors, such as fluid flow and space avoidance, and jointly improve the durability and stability of the overall structure.

[0041] Further as Figure 2 As shown, elastic sealing rings 100 are provided at the connection between the drive tube seat 2 and the inner wall of the double-disc tube seat 11, the connection between the fixed tube seat 3 and the inner wall of the double-disc tube seat 11 and the inner wall of the single-disc tube seat 12, and the connection between the threaded ring frame 30 and the surface of the transmission shaft rod 22.

[0042] Specifically, the multi-position setting of the elastic sealing ring 100 forms an all-round sealing system. In conjunction with the rubber sealing gasket 7, it covers all the key parts of the connector that may leak, from dynamic fit, sliding fit to threaded fit. This not only solves the fluid leakage problem caused by insufficient sealing in traditional pipe connections, but also improves the reliability of the connector in complex environments (such as humid and dusty scenarios) through protection. It is an important guarantee for achieving the dual goals of "stable connection + efficient sealing".

[0043] Further as Figure 5As shown, rubber gaskets 7 are provided between the flanges of the left pipe 4 and the right pipe 5 and the flanges of the corresponding single-disc pipe seat 12. The rubber gaskets 7 are sleeved on the outside of the fixed shaft 32.

[0044] Specifically, although the pipe flange and the single-flanged pipe seat 12 flange are tightly pressed together by the thrust of the second elastic clamp 33, minor scratches or unevenness are inevitable on the surface of the metal flange. The rubber gasket 7, utilizing the high elasticity of rubber, deforms under pressure and can completely fill the gap between the two flanges, forming a gapless seal. This effectively prevents fluid (liquid or gas) leakage from the flange connection surface, compensating for the shortcomings of hard metal contact sealing. When the fixed shaft 32 pushes the pipe flange closer to the single-flanged pipe seat 12, the rubber gasket 7 can buffer the impact force at the moment of contact, preventing the metal flange from deforming or being damaged due to hard collision. The rubber material can isolate the direct metal contact between the pipe flange and the single-flanged pipe seat 12 flange, reducing the electrochemical corrosion that may occur between different metal materials (especially when transporting corrosive fluids). In environments with poor humidity or dampness, the rubber gasket 7 is fitted on the outside of the fixed shaft 32. Its through hole fits tightly with the surface of the shaft, which can simultaneously seal the gap between the fixed shaft 32 and the pipe flange and the single-disc pipe seat 12 flange, preventing fluid from seeping along the surface of the shaft, forming a double seal of the flange face and the circumferential direction of the shaft, further improving the overall sealing performance. The rubber gasket 7 and the elastic sealing ring 100 together constitute a multi-layer sealing system for the connector. The elastic sealing ring 100 is mainly for sealing dynamic mating parts (such as the rotation of the drive pipe seat 2 and the sliding of the fixed pipe seat 3), while the rubber gasket 7 focuses on sealing the static flange connection surface. The two cover all the key nodes of the connector that may leak, which greatly improves the sealing reliability of the pipeline connection and reduces maintenance costs and safety hazards.

[0045] Further as Figure 2 As shown, the surface of the drive tube seat 2 is uniformly provided with weight reduction grooves 200, and the inner flange surface of the two sets of double-disc tube seats 11 is provided with two sets of locking holes 111, and the included angle between the two locking holes 111 in the same set is 180°.

[0046] Specifically, the weight-reducing groove 200 design reduces the overall weight by removing excess material while ensuring the structural strength of the drive tube seat 2, thereby reducing the installation load on the connectors (especially in large piping systems, it can reduce the load-bearing pressure on the supporting structure). It also facilitates transportation and assembly. The evenly distributed weight-reducing groove 200 makes the mass distribution of the drive tube seat 2 more balanced, which can reduce the centrifugal force and vibration caused by the shift of the center of gravity during rotation, ensuring a smoother rotational fit with the inner wall of the double-disc tube seat 11 and avoiding component wear caused by vibration. The weight-reducing groove 200 structure can increase the grip friction of the hand or tools, making it easier to rotate the drive tube seat 2 during installation (especially in manual adjustment scenarios), thus improving assembly efficiency.

[0047] The two sets of locking holes 111 correspond to the "initial unfixed state" and "final fixed state" of the drive tube seat 2, respectively. When the drive tube seat 2 rotates, the first elastic locking member 21 disengages from the first set of locking holes 111, rotates 180°, and then engages with the second set of locking holes 111. At this time, the drive tube seat 2 is stably locked, ensuring that the positions of components such as the transmission shaft 22 and the eccentric fixing block 24 are accurately in place, providing a reliable reference for internal and external fixing actions. The 180° included angle design is perfectly matched with the rotation stroke of the transmission shaft 22. When the drive tube seat 2 rotates 180°, the transmission shaft 22 rotates 180° synchronously, which can drive the threaded part 23 to drive the fixed tube seat 3 to slide to the preset position (complete external fixing), while causing the eccentric fixing block 24 to rotate to the position of abutting the pipe insertion section 6 (complete internal fixing), realizing the precise coordination of the "rotation-sliding-clamping" action.

[0048] The working principle of this utility model is as follows: This utility model achieves the coordinated action of "internal fixation + external fixation" by rotating the drive tube seat 2. The specific process is as follows:

[0049] Initial assembly stage: Insert the insertion sections 6 of the left pipe 4 and the right pipe 5 into the fixed pipe seat 3 and fit them on the outside of the eccentric positioning ring seat 31 (at this time, the eccentric fixing block 24 does not contact the inner wall of the insertion section 6); the pipe flange is fitted on the outside of the fixed shaft 32, located inside the second elastic clamp 33, and maintains a certain distance from the single disc pipe seat 12.

[0050] Drive rotation stage: Rotate the drive tube seat 2 so that the first elastic retainer 21 on its surface disengages from the first set of retaining holes 111 of the double-disc tube seat 11 and finally engages with the second set of retaining holes 111 (the angle between the two sets of retaining holes 111 is 180°). During this process, the drive tube seat 2 drives the transmission shaft 22 to rotate synchronously through the fixed ring frame 20.

[0051] External fixing action: When the threaded part 23 of the transmission shaft 22 (two sets of threads in opposite directions) rotates, it drives the two sets of fixed pipe seats 3 to slide horizontally inward through the threaded ring frame 30; the fixed pipe seats 3 drive the fixed shaft 32 to move synchronously, and the second elastic clip 33 pushes the pipe flange closer to the single disc pipe seat 12 until the two are tightly fitted by the rubber sealing gasket 7, thus completing the external fixing.

[0052] Internal fixation action: While the drive shaft 22 rotates, the eccentric fixing block 24 at its end rotates 180° synchronously, changing from an initial non-contact state to abutting the inner wall of the insertion section 6, and cooperating with the eccentric positioning ring seat 31 to form a bidirectional clamping of the insertion section 6, thus completing the internal fixation.

[0053] Sealing and Coordination Stage: During the sliding of the fixed pipe seat 3 and the rotation of the eccentric fixed block 24, the elastic sealing ring 100 and the rubber sealing gasket 7 are compressed due to the contact of the components, forming a tight seal and ensuring the fluid sealing of the connection.

[0054] The above process achieves "one-click" fixing and sealing of pipe connections, balancing stability and ease of operation.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
