An external sealing ring 12 is installed at the connection between the two to ensure effective isolation between the external environment and the internal fluid passage and prevent fluid leakage.

[0033] The female end valve body C is the core functional component of the female end, which includes the female end valve core 4, the female end reset spring 10 and the female end valve column 11. The female end valve core 4 is installed on the upper end of the female end reset spring 10, and the female end reset spring 10 is installed on the upper part of the female end valve column 11.

[0034] The male end A is composed of a male end upper shell 13, a male end lower shell 14, a male end upper shell locking nut 15, a male end upper shell locking sleeve 16 and a male end locking cover 17. The male end upper shell 13 is connected and disassembled with the male end lower shell 14 through the male end upper shell locking nut 15, which is convenient for assembly and adjustment of internal parts. The male end upper shell locking sleeve 16 is connected and disassembled with the male end upper shell locking nut 15, and the male end locking cover 17 is connected and disassembled with the male end upper shell 13, which provides stable packaging and protection for the internal structure. The male end upper shell 13 is internally provided with a male end valve body D, which includes a male end deviation correction rod 18, a male end valve core 20 and a male end reset spring 26. The male end deviation correction rod 18 is installed on the top of the male end reset spring 26, the outer ring is provided with two sets of deviation correction sealing rings 21, the bottom is provided with a male end spring support seat 19, and the upper end of the male end spring support seat 19 is provided with a male end stop snap spring 23. These structural designs ensure the stability and sealing performance of the male end deviation correction rod 18 during movement. The male end valve core 20 is installed on the bottom of the male end reset spring 26, and the bottom is provided with a male end valve core sealing ring 25, which cooperates with the corresponding structure of the female end to realize sealing and conduction function during connection and disconnection. The male end lower shell 14 is provided with a male end color identification ring 24, which corresponds to the female end color identification ring 5, and is convenient for distinguishing the male and female ends. The male end upper shell 13 is provided with a male end outer sealing ring 22 to prevent external impurities from entering and ensure the overall sealing performance of the male end. The middle segment of the male end upper shell 13 is provided with an arc surface 130, which plays a good guiding role in the initial stage of connection, helps the male end to be smoothly inserted into the female end, and can guide the two to gradually align even if there is a certain deviation.

[0035] The male end deviation correction rod 18 is in the top position under the action of the male end reset spring 26, the male end valve core 20 is in the bottom position, the male end valve core sealing ring 25 contacts the corresponding sealing surface inside the male end lower shell 14, the male end stop snap spring 23 clamps the male end spring support seat 19, preventing the male end reset spring 26 from being compressed too much or the male end deviation correction rod 18 from coming out. The male end outer sealing ring 22 ensures the sealing between the male end upper shell 13 and the outside.

[0036] The female valve core 4 is in the top position under the action of the female reset spring 10, the female connecting seal ring 6 and the female inner seal ring 7 are in contact with the corresponding sealing surfaces inside the female upper shell 1 and the female lower shell 2, the female valve core seal ring 9 is in contact with the top sealing surface of the female valve post 11, and the female outer seal ring 12 ensures the sealing of the connection between the female upper shell 1 and the female lower shell 2.

[0037] When the male end A starts to dock with the female end B, the male end plug approaches the female end connector. Because the middle section of the male end upper shell 13 is provided with an arc surface 130, it facilitates the preliminary guidance of docking to a certain extent, and the arc surface structure of the male end upper shell 13, which can be understood as the movable structure formed by the connection part of the male end upper shell 13 and the male end lower shell 14, can adapt to the position of the female end within a certain range, that is, even if there is a certain coaxiality deviation and angle deviation, the arc surface structure of the male end upper shell 13 can realize radial deviation or rotation around the spherical center to automatically absorb the position deviation.

[0038] With the further insertion of the male end plug into the female end connector, the end face of the male end plug gradually abuts against the end face of the valve core inside the female end connector, and the valve core inside the male end plug also gradually abuts against the end face of the center support column of the lower shell of the female end connector. In this process, the male end correction rod 18 is compressed, the male end reset spring 26 is deformed under stress, the male end valve core 20 moves upward, and the male end valve core seal ring 25 is separated from the contact with the sealing surface inside the male end lower shell 14; at the same time, the female end valve core 4 is compressed, the female end reset spring 10 is deformed under stress, the female end connecting seal ring 6 and the female end inner seal ring 7 are separated from the contact with the sealing surface inside the female end upper shell 1 and the female end lower shell 2, and the female end valve core seal ring 9 is separated from the contact with the top sealing surface of the female end valve post 11, thereby realizing the passage for fluid flow.

[0039] When the male end plug and the female end connector need to be disconnected, an external force is applied to pull the male end plug outward. The male end reset spring 26 begins to recover the deformation, pushes the male end correction rod 18 back to the initial position, and the male end valve core 20 moves downward, and the male end valve core seal ring 25 recontacts with the sealing surface inside the male end lower shell 14; at the same time, the female end reset spring 10 recovers the deformation, pushes the female end valve core 4 back to the initial position, and the female end connecting seal ring 6 and the female end inner seal ring 7 recontact with the sealing surface inside the female end upper shell 1 and the female end lower shell 2, and the female end valve core seal ring 9 recontacts with the top sealing surface of the female end valve post 11, thereby realizing the bidirectional quick sealing and cutting off the flow to prevent fluid from overflowing.

[0040] The arc surface structure of the male upper shell 13 and the related design enable the male end and the female end to automatically absorb position deviation, coaxiality deviation and angle deviation when connected, which greatly improves the convenience and success rate of the connector during blind assembly operation. The operator does not need to accurately align the male end and the female end, and the connection can be successfully completed even within a certain deviation range, reducing the assembly time and difficulty, especially suitable for some connection scenarios that are difficult to directly observe or have limited operation space.

[0041] In both connected and disconnected states, there are corresponding sealing ring structures to ensure sealing. When connected, the sealing ring is separated from contact by the movement of the valve core to achieve passage, and when disconnected, the sealing ring can quickly restore the sealing state, effectively preventing fluid leakage, with good bidirectional sealing and blocking effect, ensuring the sealing and stability of the system, and being applicable to various fluid transmission systems with high sealing requirements.

[0042] The reset springs and stop springs of the male end and the female end are formed by winding, and the rest of the parts except the sealing ring are formed by injection molding or machining, which not only ensures the accuracy and strength of the parts, but also facilitates large-scale production. Each part has clear division of labor, and through reasonable assembly, a complete connector function system is formed, for example, the valve core, spring and other parts in the male valve body D and the female valve body C work together to realize the switching of connection and sealing functions, and the overall structure is compact and efficient.

[0043] The blind assembly connector with deviation absorption function has wide application prospects in many industrial fields due to its unique advantages. In the field of aerospace, there are numerous hydraulic and pneumatic systems inside the aircraft, and the space is limited. This connector can conveniently and quickly realize pipeline connection, improve assembly efficiency and ensure system reliability; in the automotive manufacturing industry, the connection of various fluid pipelines in the engine compartment can also benefit from its blind assembly characteristics, reducing assembly time and cost; in industrial automation production lines, a large number of fluid transmission pipelines need to be frequently connected and disconnected, and the quick blind assembly and reliable sealing performance of this connector can significantly improve the operation efficiency and stability of the production line. With the continuous development of industrial technology, the performance requirements for connectors will be higher and higher, and the blind assembly connector with deviation absorption function is expected to be applied and popularized in more fields, and with the progress of material science and manufacturing technology, its performance will be further optimized, such as improving the high pressure resistance, high temperature resistance and corrosion resistance, to meet the more demanding requirements of industrial environments and make greater contributions to the development of industrial connection technology.

[0044] The blind connector with the function of absorbing deviation has obvious advantages in the field of industrial connection with its innovative structure design, excellent blind connection ability, reliable sealing performance, reasonable manufacturing process and clear identification design. By elaborating its structure composition, connection process movement principle and structure advantages, it can be seen that the connector has important value in improving assembly efficiency, guaranteeing system sealing and stable operation.
