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

[0038] The female end is composed of a female end upper shell 1, a female end lower shell 2, a female end sleeve 3 and a female end valve body C. The female end upper shell 1 and the female end lower shell 2 are combined in a detachable connection manner, and a female end outer sealing ring 11 is installed at the connection between the two to ensure external sealing and prevent fluid leakage from the shell connection.

[0039] The female valve body C is installed inside the female upper shell 1 and the female lower shell 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. A female valve core sealing ring 9 is provided on the top of the female valve column 11. These sealing rings cooperate with the valve core, valve column, etc. to form a strict internal sealing structure to control the fluid passage. The female end B is provided with a female color identification ring 5 on the outside to facilitate identification of female ends of different specifications or uses.

[0040] The male end is composed of a male end upper shell 13, a male end lower shell 14, a male end elastic locking nut 15, a male end plug cup 18 and a male end correction elastic body 19. The male end upper shell 13 and the male end lower shell 14 are also disassembled and connected, and a male end connection sealing ring 16 is installed at the connection to ensure internal sealing. The male end elastic locking nut 15 is connected to the upper part of the male end plug cup 18, and the male end correction elastic body 19 is installed inside the male end plug cup 18.

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

[0042] The male end A and the female end B are assembled by plugging, and the through hole on the female end sub-assembly of the connecting device accommodates the male end upper shell 13. When the male end plug and the female end connector are in a connected state, the end face of the male end plug abuts against the end face of the valve core in the female end connector, and the valve core in the male end plug abuts against the end face of the central support column of the lower shell of the female end connector, and is out of contact with the respective sealing ring structures that cooperate with each other to achieve a passage for fluid to flow through.

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

[0044] If there is a position deviation, coaxial deviation and angle deviation between the male end plug and the female end plug, since the outer side of the male end upper shell 13 is connected to the male end correction elastomer 19, the male end correction elastomer 19 is composed of a stopping layer 190, an elastic layer 191 and a connecting layer 192, wherein the elastic layer 191 is a V-folded shape with good elastic deformation ability, so that the male end upper shell 13 can be offset along its radial direction or rotate around a certain point, automatically absorbing the position deviation, ensuring a reliable connection between the male end and the female end, and not affecting the fluid transmission.

[0045] When the male plug and the female connector are in a disconnected state, the end face of the male plug and the end face of the valve core in the female connector are separated from each other and no longer abutted, the valve core in the male plug and the end face supported by the center of the lower shell of the female connector are separated from each other and no longer abutted, the valve cores of the male and female ends are reset under the action of the reset springs, and contact with their respective sealing ring structures to form a two-way rapid sealing interception, effectively preventing fluid overflow.

[0046] The male and female ends are provided with sealing ring structures at multiple locations, which can accurately switch between sealing and passage in the connected and disconnected states. The fluid can pass smoothly when connected, and fluid leakage can be prevented when disconnected. The double sealing guarantee greatly improves the sealing reliability of the device, and is suitable for fluid transmission systems with high sealing requirements. 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 ensure the sealing effect.

[0047] The female and male sub-parts are assembled separately through auxiliary equipment to form the female sub-assembly and male sub-assembly of the connection device. This modular assembly method is convenient for production, quality control and later maintenance and repair, improves production efficiency and reduces production costs. At the same time, if a component fails, it can be replaced in a targeted manner to reduce the difficulty and cost of maintenance. For example, the female upper shell 1, the female lower shell 2 and other parts form the female sub-assembly, which is easy to manage and operate.

[0048] The female end color identification ring 5 provided at the female end facilitates 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 connection, and improve the assembly accuracy of the overall system.

[0049] When the male end A and the female end B begin to be plugged in, the male end upper shell 13 is the key moving part, and the male end correction elastic body 19 connected to its outside is always ready to deal with possible position deviations. The unique three-ring ring structure of the male end correction elastic body 19 plays its respective role: the stop layer 190 is firmly fixed at the connection between the male end elastic locking nut 15 and the male end plug cup 18, providing a solid basic support for the entire correction process to prevent 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 connection layer 192 fits tightly to the outside of the male end upper shell 13, ensuring that the male end upper shell 13 can accurately receive and respond to the deformation force transmitted by the elastic layer 191.

[0050] Assume that during the plug-in process, there is a coaxial deviation between the male end and the female end, that is, the central axes of the two are not in the same straight line. At this time, when the male end is pushed toward the female end, one side of the male end upper shell 13 will first contact the corresponding part of the female end and be subjected to uneven resistance force. Due to the existence of the elastic layer 191, the elastic layer 191 on this side will be quickly compressed and deformed, and the elastic force generated by the deformation will react on the male end upper shell 13, pushing the male end upper shell 13 to move in the direction of alignment with the central axis, causing the male end plug end face to gradually approach and finally accurately align with the valve core end face in the female end connector. This adjustment process is dynamic and continuous, and the male end upper shell 13 will continue to fine-tune as the insertion goes deeper until a reliable connection is achieved.

[0051] If there is an angle deviation, for example, the male end is tilted at a certain angle relative to the female end. When the male upper shell 13 is inserted, the connection area between the connecting layer 192 and the male upper shell 13 is similar to the "rotation axis". Driven by the elastic force of the elastic layer 191, the male upper shell 13 begins to slowly rotate around this point. The stretching or compression of the elastic layer 191 in different directions coordinates with the rotation action, so that the valve core in the male plug can flexibly adjust the angle and accurately abut against the end face of the central support column of the lower shell of the female connector, ensuring the smooth docking of the fluid channel and allowing the entire plug-in process to smoothly transition to the connected state.

[0052] In various complex industrial scenarios, the installation environment of pipelines varies greatly. Some have cramped spaces and difficult operations; some are affected by the vibration of the surrounding equipment, and the pipelines are prone to displacement; and some are due to early planning problems, and the initial conditions for the male and female ends to connect are not good. However, with the ingenious design of the male end correction elastomer 19, the connection device can easily cope with these problems. It provides a certain amount of fault tolerance, allowing the male and female ends to have position deviations when plugged in, and automatically adjusts and adapts, which greatly expands its applicable fields and working conditions. Whether it is the connection of fluid transmission pipelines in the chemical, machinery manufacturing or automotive industries, it can play a stable role. The automatic correction function fundamentally eliminates the hidden dangers of loose connections caused by position deviations. Stable and reliable connections not only ensure that the fluid can be continuously and smoothly transmitted between pipelines, avoiding the risk of leakage, but also lay a solid foundation for the safe operation of the entire fluid system. In the long-term operation process, the number of equipment shutdowns and repairs due to poor connections is reduced, maintenance costs are reduced, production efficiency is improved, the smooth operation of the production line is guaranteed, and greater economic benefits are created for the enterprise.

[0053] For operators, the installation of the connection device required for traditional high-precision docking is difficult and time-consuming, and requires professional skills and rich experience. The automatic deviation correction function of this connection device greatly simplifies the installation process. Operators no longer need to repeatedly calibrate for millimeter-level or even smaller position deviations. They only need to roughly align and plug in, and the male end can automatically complete accurate docking. It can greatly shorten the installation time, improve work efficiency, and speed up project progress.

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