[0029] Example

[0030] like Figures 1-5 As shown, a rotary locking sleeve mechanism includes a male end A and a female end B, which are inserted and connected. The female end B includes an upper female end housing 1, a lower female end housing 2, and a female end valve body C. A female end locking sleeve 10 is provided at the connection between the upper female end housing 1 and the lower female end housing 2. A female end locking device 11 is installed on the top of the female end locking sleeve 10. The female end valve body C is installed inside the female end B. The male end A includes a male end housing 14 and a male end valve body D, which is installed inside the male end housing 14. The female end valve body C includes a sleeve 3, a female end valve core 4, a female end return spring 9, and a female end valve column 13. The female end valve core 4 is located inside the sleeve 3, and the female end return spring 9 is installed between the female end valve core 4 and the female end valve column 13.

[0031] The top of the sleeve 3 is provided with two sets of female end inner sealing rings 6, and a female end isolation ring 7 is provided between the two sets of female end inner sealing rings 6. The upper end of the female end valve column 13 is provided with a female end valve core sealing ring 8. The female end locker 11 includes a locking part 110, a pressing part 111 and a female end locker return spring 12. The pressing part 111 is located on one side of the locking part 110. One end of the female end locker return spring 12 is connected to the inner side of the pressing part 111, and the other end is connected to the outer wall of the female end upper housing 1.

[0032] The top of the female end upper housing 1 is provided with a mating groove 180 and two sets of mating protrusions 190. The mating protrusions 190 are located on the lower side of the mating groove 180. The female end locking sleeve 10 is provided with a rotating groove 100 and two sets of locking protrusions 101. The female end locker return spring 12 passes through the rotating groove 100. The locking protrusions 101 and the mating protrusions 190 cooperate. In the locked state, one set of locking protrusions 101 locks the female end locker 11. The male end valve body D includes a male end anti-reverse ring 15, a male end valve core 16 and a male end return spring 18. The top end of the male end return spring 18 is connected to the male end anti-reverse ring 15, and the other end is connected to the male end valve core 16.

[0033] The male valve core 16 has a male valve core sealing ring 17 at its bottom end, the male housing 14 has an external sealing ring 20 at its upper interface, and the male housing 14 has a male color identification ring 19 on its outer side.

[0034] The outer ring of the lower female shell 2 is provided with a female color identification ring 5, and the lower end of the male shell is sloped at the connection with the female end.

[0035] During the locking process, after the male end A is inserted into the female end B, the female end locking device 11 is pushed outward to its locking position by the return spring, locking the male end A. When the male end A and the female end B are connected, the male end valve body D and the female end valve body C abut against each other, and the male end valve core 16 of the male end valve body D abuts against the end face of the female end valve column 13 at the center of the lower housing 2 of the female end, and disengages from their respective sealing ring structures to achieve passage so that fluid can flow through. After the male end A is installed in place, the female end locking sleeve 10 is rotated so that the mating protrusion 190 rotates to the mating protrusion 190 position. At the same time, one set of locking protrusions 101 rotates to the inside of the pressing part 111, preventing the female end locking device 11 from pressing down. At this time, the female end locking device 11 cannot be locked, thereby preventing the locking mechanism from being mis-locked.

[0036] During the unlocking process, first move the female locking sleeve 10 to the maximum unlocking position, causing one set of locking protrusions 101 to rotate away from the inside of the pressing part 111. Then, press the female locking device 11 to its unlocking position, causing the female locking device 11 to release the male end A, allowing the male end A to smoothly move out of the inner cavity of the female end B.

[0037] After male end A is completely removed from the inner cavity of female end B, the locking device is released. Under the push of the female end locking device return spring 12, it springs back to the locked position.

[0038] When male end A and female end B are disconnected, the valve core end faces inside male end valve body D and female end valve body C are separated from each other and no longer abut. Male end valve core 16 and female end valve core 4's female end valve column 13 are also separated from each other and no longer abut. Instead, they contact their respective sealing ring structures to prevent fluid overflow and achieve bidirectional rapid sealing and flow interception.

[0039] The upper housing 1 and the lower housing 2 of the female end together form the external frame of the female end, providing a mounting base and protection for the internal components. Its structural design is reasonable, facilitating the assembly and maintenance of internal components, and the connections are robust, ensuring the stability of the overall structure.

[0040] The sleeve 3 serves as the mounting carrier for components such as the female valve core 4, playing a positioning and guiding role, ensuring that the female valve core 4 can move accurately inside it, and ensuring the stability of the fluid passage.

[0041] The female valve core 4, in cooperation with the female return spring 9 and the female valve spool 13, achieves fluid flow control. Its advantage is that it is highly responsive and can quickly and accurately control the fluid flow state.

[0042] The female end return spring 9 provides the return force, enabling the female end valve core 4 to return to its initial position when no external force is applied, thus ensuring the valve's sealing performance and stability.

[0043] The female valve stem 13 works in conjunction with the female valve core 4, and the female valve core sealing ring 8 at its upper end enhances the sealing performance to prevent fluid leakage.

[0044] The female end locking sleeve 10 is provided with a rotating groove 100 and a locking protrusion 101. The rotating groove 100 facilitates the installation and movement of the female end locker return spring 12. The locking protrusion 101 cooperates with the mating protrusion 190 of the female end upper housing 1 to realize the key actions of locking and unlocking. Different working states can be achieved by rotation, which is convenient and reliable to operate.

[0045] The female end lock 11 consists of a locking part 110, a pressing part 111, and a female end lock return spring 12. The locking part 110 can quickly lock the male end A under the action of the return spring, the pressing part 111 facilitates the unlocking operation by the operator, and the female end lock return spring 12 ensures the automatic reset function of the lock, making the operation of the entire mechanism more convenient and efficient.

[0046] The inner sealing ring 6 and the inner sealing ring 7 of the female end serve a sealing function to prevent fluid leakage from the top of the sleeve 3. The inner sealing ring 6 of the female end between the two sets of inner sealing rings 6 helps to improve the sealing effect, while protecting the sealing ring and extending its service life.

[0047] The male end housing 14 provides protection and installation space for the male end valve body D. The male end outer sealing ring 20 at its upper interface enhances the sealing performance when the male end is connected to the female end. The male end color identification ring 19 on the outside facilitates identification and differentiation of male ends of different specifications or uses.

[0048] The mechanism is divided into male end A and female end B. The female end is further subdivided into several components, such as the upper female end housing 1, the lower female end housing 2, and the female end valve body C. The male end also has components such as the male end housing 14 and the male end valve body D. This modular design makes the function of each component clear, facilitating individual manufacturing, installation, and maintenance. For example, when the female end valve body C malfunctions, it can be directly removed from the female end B for repair or replacement without affecting the normal operation of other components.

[0049] The connection between the upper female housing 1 and the lower female housing 2 is secure, providing a stable mounting base for the internal components. The female locking sleeve 10 and the upper female housing 1, through the cooperation of the mating protrusion 190 and the locking protrusion 101, as well as the locking action of the female locking device 11, ensure that the male end A and the female end B will not easily loosen or fall off after connection, thus guaranteeing the reliability of the entire mechanism during operation.

[0050] The sleeve 3 in the female valve body C provides precise positioning and guidance for the female valve core 4, ensuring that the female valve core 4 can move accurately within it, thereby ensuring the stability of the fluid passage. Similarly, the male check ring 15 in the male valve body D also restricts the range of motion of the male valve core 16, ensuring that it works in the appropriate position and improving the overall performance of the mechanism.

[0051] The top of the sleeve 3 of the female valve body C is equipped with two sets of female inner sealing rings 6, and a female isolation ring 7 is provided between the two sets of female inner sealing rings 6, which enhances the sealing effect and prevents fluid leakage from the top of the sleeve 3. The upper end of the female valve stem 13 is equipped with a female valve core sealing ring 8, the bottom end of the male valve core 16 is equipped with a male valve core sealing ring 17, and the upper interface of the male housing 14 is equipped with a male outer sealing ring 20. When the male end A and the female end B are disconnected, these sealing rings can make tight contact, realize bidirectional rapid sealing and interception, effectively prevent fluid overflow, and ensure the safety and reliability of the system.

[0052] The female end isolation ring 7 not only helps improve the sealing effect, but also protects the inner sealing ring 6 of the female end, extending its service life. In actual operation, the flow of fluid may cause some erosion and wear to the sealing ring. The presence of the female end isolation ring 7 can reduce this impact, reduce the replacement frequency of the sealing ring, and reduce maintenance costs.

[0053] After the male end A is inserted into the female end B, the female end locking device 11, pushed by the female end locking device return spring 12, can quickly and automatically lock the male end A without any additional complicated operations, greatly improving the connection efficiency. During the connection process, the valve cores of the male end valve body D and the female end valve body C can automatically cooperate to realize the rapid opening of the fluid passage and facilitate the flow of fluid.

[0054] After male end A is installed in place, rotating the female end locking sleeve 10 causes one set of locking protrusions 101 to rotate to the inside of the pressing part 111 of the female end locker 11, preventing the female end locker 11 from pressing down and preventing the locking mechanism from being mis-locked. This design is very practical in actual use, avoiding loosening or disconnection of the connection due to misoperation, and improving the safety and stability of the system.

[0055] The unlocking process is simple. First, move the female locking sleeve 10 to the maximum unlock position to release the restriction on the female locking device 11. Then, press the female locking device 11 to release the male terminal A. After the male terminal A is completely removed, the female locking device 11 will automatically spring back to the locked position under the action of the female locking device return spring 12, preparing for the next connection of the male terminal A. The entire operation is smooth and efficient. The male terminal housing 14 has a male terminal color identification ring 19 on its outer side, and the female terminal lower housing 2 has a female terminal color identification ring 5 on its outer ring. These color identification rings make it easy for operators to quickly identify and distinguish male and female terminals of different specifications or uses among many connecting parts, improving work efficiency and reducing failures and losses caused by incorrect connections.

[0056] The unlocking operation is simple: first, move the female locking sleeve 10 to the maximum unlock position to release the restriction on the female locking device 11; then, press the female locking device 11 to release the male terminal A.
