Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, specifically relating to a connection device that can correct deviations. Background Technology

[0002] Traditional pipe connection devices typically employ simple plug-in or threaded connections. Under ideal installation conditions, these can generally meet fluid transmission requirements. However, real-world industrial scenarios are complex and varied, and numerous problems have gradually emerged. On the one hand, installation space is often limited. The confined operating space makes it difficult for operators to precisely align the male and female terminals according to high-precision requirements. Even minor operational errors can easily cause coaxiality or angular deviations, leading to loose connections and the risk of fluid leakage.

[0003] With the acceleration of industrial automation, greater challenges are being placed on the ease of installation of connection devices. Traditional connection methods rely on experienced technicians for precise calibration, resulting in high labor costs and low installation efficiency, making it difficult to meet the pace of rapidly developing industrial production.

[0004] In some precision manufacturing fields where the stability of fluid transmission is critical, even the slightest loosening of connections or positional deviation can introduce impurities, affect product quality, increase the defect rate, and cause huge economic losses to enterprises. Utility Model Content

The male end alignment elastic body is installed inside the male end plug cup. The upper male end housing and the lower male end housing are connected and pass through the male end plug cup. A male end valve core is provided inside the upper male end housing.

[0009] Furthermore, a male sheet metal nut is installed at the bottom of the male plug cup, and sheet metal is provided between the male plug cup and the male sheet metal nut.

[0028] Example

[0029] like Figure 1-4 As shown, a connection device capable of correcting deviation includes a male end A and a female end B. The male end A and the female end B are plugged into each other. The female end B includes an upper female end housing 1, a lower female end housing 2, a female end sleeve 3, and a female end valve body C. The upper female end housing 1 and the lower female end housing 2 are detachably connected. The female end valve body C is installed inside the upper female end housing 1 and the lower female end housing 2.

[0030] The male end A includes an upper male end housing 13, a lower male end housing 14, a male end elastic locking nut 15, a male end plug cup 18, and a male end alignment elastic body 19. The upper male end housing 13 and the lower male end housing 14 are detachably connected. The male end elastic locking nut 15 is connected to the upper part of the male end plug cup 18. The male end alignment elastic body 19 is installed inside the male end plug cup 18. After the upper male end housing 13 and the lower male end housing 14 are connected, they pass through the male end plug cup 18. The upper male end housing 13 is provided with a male end valve core 22.

[0031] The bottom of the male plug cup 18 is fitted with a male sheet metal nut 17, and a sheet metal 21 is provided between the male plug cup 18 and the male sheet metal nut 17.

[0032] A male end connection sealing ring 16 is installed at the connection between the male end upper housing 13 and the male end lower housing 14.

[0033] The male valve core 22 has a male valve core sealing ring 23 at the bottom and a male return spring 20 connected to the top of the male valve core 22.

[0034] The female valve body C includes a female valve core 4, a female return spring 10, and a female valve stem 12. The female valve core 4 is mounted on the upper end of the female return spring 10, and the female return spring 10 is mounted on the upper part of the female valve stem 12.

[0035] The outside of the female end B is equipped with a female end color identification ring 5.

[0036] The upper part of the female valve core 4 is provided with a female end connecting sealing ring 6, the lower part of the female end connecting sealing ring 6 is provided with a female end inner sealing ring 7, a female end isolation ring 8 is provided between the female end connecting sealing ring 6 and the female end inner sealing ring 7, and the top of the female end valve column 12 is provided with a female end valve core sealing ring 9.

[0037] The male end correction elastomer 19 is composed of a three-ring structure, which includes a locking layer 190, an elastic layer 191, and a connecting layer 192. The locking layer 190 is located at the connection between the male end elastic locking nut 15 and the male end plug cup 18. The elastic layer 191 is V-shaped. The connecting layer 192 is connected to the outside of the male end upper shell 13.

[0038] The female end consists of an upper female end housing 1, a lower female end housing 2, a female end sleeve 3, and a female end valve body C. The upper female end housing 1 and the lower female end housing 2 are combined by a detachable connection, and an external sealing ring 11 is installed at the connection point to ensure external sealing and prevent fluid leakage from the housing connection point.

[0039] The female valve body C is installed inside the upper female valve housing 1 and the lower female valve housing 2. The female valve core 4 in the female valve body C is installed on the upper end of the female return spring 10. The female return spring 10 is installed on the upper part of the female valve column 12. The upper part of the female valve core 4 is provided with a female connection sealing ring 6, and the lower part is provided with a female inner sealing ring 7. A female isolation ring 8 is provided between the female connection sealing ring 6 and the female inner sealing ring 7. The top of the female valve column 12 is provided with a female valve core sealing ring 9. These sealing rings, together with the valve core and valve column, form a tight internal sealing structure to control the fluid passage. The female valve B is provided with a female color identification ring 5 on the outside to facilitate the identification of female valves of different specifications or uses.

[0040] The male connector consists of an upper male connector housing 13, a lower male connector housing 14, a male connector elastic locking nut 15, a male connector plug cup 18, and a male connector alignment elastic body 19. The upper male connector housing 13 and the lower male connector housing 14 are also detachably connected, with a male connector sealing ring 16 installed at the connection point to ensure internal sealing. The male connector elastic locking nut 15 is connected to the upper part of the male connector plug cup 18, and the male connector alignment elastic body 19 is installed inside the male connector plug cup 18.

[0041] After the male end upper housing 13 and male end lower housing 14 are connected, they pass through the male end plug cup 18. The male end upper housing 13 is provided with a male end valve core 22. The male end valve core 22 is provided with a male end valve core sealing ring 23 at the bottom and a male end return spring 20 connected to the top. A male end sheet metal nut 17 is installed at the bottom of the male end plug cup 18. A sheet metal 21 is provided between the two to enhance the structural stability.

[0042] Male end A and female end B are assembled by plugging in. The through hole on the female end sub-assembly of the connecting device accommodates the upper housing 13 of the male end. When the male end plug and the female end connector are in the connected state, the end face of the male end plug abuts against the end face of the valve core inside the female end connector, and the valve core inside the male end plug abuts against the end face of the central support column of the lower housing of the female end connector, and disengages from the sealing ring structure that is used for sealing, so as to achieve passage so that fluid can flow through.

[0043] When the male and female ends are plugged in, the male plug face pushes the female valve core 4 to move downward against the elastic force of the female return spring 10. At the same time, the male valve core 22 also abuts against the end face of the central support column of the lower housing of the female connector under the action of the male return spring 20. At this time, the sealing ring structure of the male and female ends that were originally sealed is disengaged, the internal fluid channel is opened, and the fluid can pass smoothly through the connecting device to realize the flow between the two independent pipelines.

[0044] If there are positional, coaxial, or angular deviations between the male and female plugs, the male end upper housing 13 is connected to a male end correction elastic body 19, which consists of a locking layer 190, an elastic layer 191, and a connecting layer 192. The elastic layer 191 is V-shaped and has good elastic deformation capability, allowing the male end upper housing 13 to offset radially or rotate around a point, automatically absorbing the positional deviation and ensuring a reliable connection between the male and female ends without affecting fluid transmission.

[0045] When the male plug and female connector are disconnected, the end face of the male plug and the end face of the valve core inside the female connector are separated from each other and no longer abut. The valve core inside the male plug and the end face of the center support of the lower housing of the female connector are also separated from each other and no longer abut. The valve cores of the male and female connectors are reset under the action of the return spring and come into contact with their respective sealing ring structures to form a bidirectional rapid sealing and interception, effectively preventing fluid from overflowing.

[0046] Multiple sealing ring structures are incorporated at both the male and female ends, enabling precise switching between sealing and flow regardless of whether the connection is open or closed. This dual sealing ensures smooth fluid flow during connection and prevents leakage when disconnected, significantly improving the device's sealing reliability and making it suitable for fluid transmission systems with high sealing requirements. Features such as the male valve core sealing ring 23 at the bottom of the male valve core 22 and a series of sealing rings around the female valve core 4 work together to guarantee a tight seal.

[0047] By assembling the various sub-components of the female and male ends separately using auxiliary equipment, the connecting device's female end sub-assembly and male end sub-assembly are formed. This modular assembly method facilitates manufacturing, quality control, and subsequent maintenance and repair, improving production efficiency and reducing production costs. Furthermore, if a component malfunctions, it can be replaced specifically, reducing repair difficulty and costs. For example, the female end upper housing 1, female end lower housing 2, and other components constitute the female end sub-assembly, facilitating management and operation.

[0048] The color-coded identification ring 5 on the female end makes it easy for operators to quickly identify female ends of different specifications or uses. In the installation of complex piping systems, it can improve installation efficiency, reduce the possibility of incorrect connections, and improve the overall system assembly accuracy.

[0049] When male terminal A and female terminal B begin to connect, the male terminal upper housing 13, as a key moving component, has a male terminal correction elastic body 19 connected to its outer side, which is always ready to deal with possible positional deviations. The unique three-ring structure of the male terminal correction elastic body 19 plays its respective role: the locking layer 190 is firmly fixed at the connection between the male terminal elastic locking nut 15 and the male terminal plug cup 18, providing a stable foundation support for the entire correction process and preventing excessive deformation from causing structural instability; the elastic layer 191, with its carefully designed V-shaped folded structure, has excellent elastic deformation potential and is the core executor of the correction action; the connecting layer 192 fits tightly against the outer side of the male terminal upper housing 13, ensuring that the male terminal upper housing 13 can accurately receive and respond to the deformation force transmitted by the elastic layer 191.

[0050] Suppose that during the insertion process, there is a coaxiality deviation between the male and female terminals, meaning their central axes are not on the same straight line. In this case, when the male terminal is pushed towards the female terminal, one side of the male terminal's upper housing 13 will first contact the corresponding part of the female terminal, experiencing uneven resistance. Due to the presence of the elastic layer 191, this side of the elastic layer 191 will be rapidly compressed, causing deformation. The elastic force generated by this deformation will then act on the male terminal's upper housing 13, pushing it towards alignment with the central axis. This will cause the male terminal plug face to gradually approach and ultimately precisely align with the valve core face inside the female terminal connector. This adjustment process is dynamic and continuous; the male terminal's upper housing 13 will continuously fine-tune as insertion deepens until a reliable connection is achieved.

[0051] If an angular deviation occurs, such as the male end tilting at a certain angle relative to the female end, the male end upper housing 13, when inserted, uses the connection area between the connecting layer 192 and the male end upper housing 13 as a kind of "rotation axis." Driven by the elastic force of the elastic layer 191, the male end upper housing 13 begins to slowly rotate around this point. The stretching or compression of the elastic layer 191 in different directions coordinates with the rotation, allowing the valve core inside the male end plug to flexibly adjust its angle and accurately abut against the end face of the central support column of the lower housing of the female end connector, ensuring smooth connection of the fluid channel and allowing the entire insertion process to smoothly transition to the connection and conduction state.

[0052] In various complex industrial scenarios, pipeline installation environments vary greatly. Some are cramped, making operation difficult; others are prone to displacement due to vibrations from surrounding equipment; still others suffer from poor initial conditions for male and female connector connection due to planning issues. However, thanks to the ingenious design of the male connector's alignment elastomer 19, this connection device can easily overcome these challenges. It provides a certain degree of tolerance, allowing for positional deviations between the male and female connectors during insertion, automatically adjusting and adapting to greatly expand its applicable fields and operating conditions. Whether in chemical, machinery manufacturing, or automotive industries, it can function stably for fluid transmission pipeline connections. The automatic alignment function fundamentally eliminates the risk of loose connections caused by positional deviations. A stable and reliable connection not only ensures continuous and smooth fluid transmission between pipelines, avoiding leakage risks, but also lays a solid foundation for the safe operation of the entire fluid system. In long-term operation, it reduces equipment downtime and maintenance due to poor connections, lowers maintenance costs, improves production efficiency, ensures smooth production line operation, and creates greater economic benefits for enterprises.

[0053] For operators, traditional high-precision docking connection devices are difficult and time-consuming to install, requiring specialized skills and extensive experience. However, the automatic correction function of this connection device significantly simplifies the installation process. Operators no longer need to repeatedly calibrate for millimeter-level or even smaller positional deviations; they only need to roughly align and plug in the connector, and the male end will automatically complete the precise docking. This greatly shortens installation time, improves work efficiency, and accelerates project progress.

[0054] In summary, the automatic correction function of this connection device, with its ingenious structural design and excellent performance, provides a reliable and efficient solution for industrial fluid transmission pipeline connections, making it an indispensable key component in modern industrial production.
