[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] In fluid transport pipeline systems, ensuring the sealing of pipeline connections and the safety of operation has always been a critical technical requirement. Existing pipeline connection devices often lack effective locking mechanisms during operation. When connections are not properly in place, valves can easily open or close accidentally due to misoperation or external forces, causing accidental fluid spillage. This not only wastes resources but may also pose a threat to the surrounding environment and personnel safety.

[0047] Therefore, such as Figures 1 to 8As shown, the fluid connector locking structure proposed in this utility model includes a body 100, a locking ball 230 disposed on the body 100, and a telescopic assembly 300 disposed on the body 100. The body 100 is provided with a rotary handle 210 and a ball valve core. The rotary handle 210 rotates to open and close the ball valve core. The telescopic assembly 300 includes a compression spring 310 and a locking pin 320. The locking pin 320 has a first mating position, a second mating position, and a third mating position with the locking ball 230 along its axial direction. The compression spring 310 connects to and drives the locking pin 320 to move axially, and drives the locking pin 320 to the first mating position. Furthermore, the outer peripheral wall of the rotary handle 210 is provided with a locking groove 2101; when in the first and third mating positions, the locking pin 320 can drive the locking ball 230 into the locking groove 2101 to prevent the rotary handle 210 from rotating. Furthermore, when in the second mating position, the locking ball 230 can disengage from the locking groove 2101, allowing the rotary handle 210 to rotate. It should be noted that, firstly, by providing a rotary handle 210 with a locking groove 2101, a locking ball 230, and a telescopic assembly 300 containing a compression spring 310 and a locking pin 320 on the main body 100, and by ensuring that the locking pin 320 and the locking ball 230 have three specific mating positions, precise control of the rotation of the rotary handle 210 is achieved. When the locking pin 320 is in the first mating position as usual, or when it is simply pressed fully into the third mating position (if not fully installed or incorrectly installed), the locking pin 320 can drive the locking ball 230 into the locking groove 2101 on the outer peripheral wall of the rotary handle 210. This effectively prevents the rotary handle 210 from rotating counterclockwise to open the ball valve, preventing accidental fluid leakage due to misoperation of the rotary handle 210. This ensures that fluid will not flow out due to improper operation when the ball valve connector 500 is in the closed state or not correctly connected, thus guaranteeing the safety and stability of the fluid delivery system. Furthermore, when the locking pin 320 is in the second mating position as normally installed and used, the locking ball 230 can disengage from the locking groove 2101, allowing the rotary handle 210 to rotate smoothly, thereby realizing the normal opening and closing operation of the ball valve. This design ensures that when the ball valve needs to be operated, the operator can smoothly control the ball valve without unnecessary obstruction, improving the convenience and efficiency of operation.

[0048] Refer to Figures 1 to 3In some embodiments of this utility model, the middle part of the locking pin 320 is provided with a first locking groove 3201, a receiving groove 3202 and a second locking groove 3203 that are sequentially connected in the axial direction of the locking pin 320, respectively corresponding to the first mating position, the second mating position and the third mating position, so that the mating between the locking pin 320 and the locking ball 230 is more precise and stable. When the locking pin 320 moves to different mating positions, the locking ball 230 can lock the rotating handle 210 through the locking groove 2101 under the pressure of the groove walls of the first locking groove 3201 and the second locking groove 3203; or, the locking pin can engage with the receiving groove 3202 to disengage from the locking groove 2101 and allow the rotating handle 210 to rotate freely. For example, corresponding to the second mating position, since the receiving groove 3202 has space to accommodate the locking ball 230, the rotation of the rotating handle 210 can push the locking ball 230 into the receiving groove 3202, ensuring the accuracy and stability of the rotation control of the rotating handle 210. Specifically, refer to... Figure 3 and Figure 4 The locking groove 2101 is semi-circular and matches the shape of the locking ball 230, allowing it to drive the locking ball 230 into the receiving groove 3202 when the rotating handle 210 is turned. This semi-circular locking groove 2101, matching the shape of the locking ball 230, significantly reduces friction and wear, extending the service life of the components. During the rotation of the rotating handle 210, this matching smoothly guides the locking ball 230 into the receiving groove 3202, making operation easier and more flexible, reducing the difficulty for operators. Simultaneously, this precise fit further enhances the stability of the locking structure, ensuring that the locking ball 230 is accurately positioned under various working conditions, effectively achieving precise control of the rotating handle 210's rotation, and enhancing the practicality and reliability of the entire fluid connector locking structure. Furthermore, the space of the receiving groove 3202 is adapted to the volume of the locking ball 230. After the locking ball 230 enters the receiving groove 3202, the locking pin 320 cannot move in the axial direction. For example, when the handle is turned to open, the locking pin 320 cannot extend or retract.

[0049] In some embodiments of this utility model, such as Figure 5As shown, the main body 100 is provided with a first limiting block 110 and a second limiting block 120. The first limiting block 110 and the second limiting block 120 are respectively located on the rotation path of the rotary handle 210 to limit the rotation angle of the rotary handle 210, preventing excessive rotation of the rotary handle 210 from damaging related components or causing seal failure. The clearly defined rotation angle range makes the opening and closing operation of the ball valve more standardized and controllable, improving the accuracy and safety of operation. At the same time, the presence of the limiting blocks also reduces the risk of misoperation caused by accidental rotation of the rotary handle 210, further ensuring the stability and reliability of the fluid delivery system and providing users with a safer and more reliable operating experience. Specifically, in the rotation direction of the rotary handle 210, the first limiting block 110 and the second limiting block 120 are 90° apart. This precise angle setting makes the rotation range of the rotary handle 210 more standardized and regulated, matching the normal opening and closing angles of the ball valve, ensuring that the ball valve can operate in the optimal working condition. Furthermore, the 90° angle design meets the operating requirements of ball valves in most fluid conveying systems, effectively preventing sealing problems or over-operation caused by inaccurate rotation angles. At the same time, this standardized design facilitates user operation and understanding, reduces operational difficulty, improves operational convenience and efficiency, and further enhances the performance and reliability of the entire fluid connector locking structure in practical applications.

[0050] In some embodiments of this utility model, the end of the locking pin 320 that is away from the compression spring 310 can extend out of the end face of the body 100. The end face of the body 100 is provided with a push-fit structure to push the locking pin 320 inward and keep it in a preset position, providing a convenient and reliable way to adjust and fix the position of the locking pin 320. The push-fit structure facilitates the accurate pushing of the locking pin 320 to the desired position and its stability. For example, during installation, it is easier to adjust the locking pin 320 to the appropriate position, ensuring the correct initial state of the entire locking structure. During maintenance, it is also easier to inspect and adjust the locking pin 320, improving the maintainability of the equipment. Simultaneously, the stable position holding function ensures reliable operation of the locking structure under different working conditions, further enhancing the practicality and stability of the fluid connector locking structure. Specifically, refer to... Figure 2 , Figure 3 , Figure 4 and Figure 6In some embodiments of this utility model, a connector 400 is also included. The connector 400 is used to engage with the end face of the body 100. The push-fit structure includes a limiting groove 101. The connector 400 presses against the end face of the body 100 to press the locking pin 320 inward. After the locking pin 320 is pressed in, the connector 400 can rotate circumferentially around the body 100 and be installed in the limiting groove 101. The introduction of the connector 400 not only enhances the connection stability and compactness of the entire structure but also further optimizes the installation and positioning process of the locking pin 320. By pressing the locking pin 320 against the end face of the body 100 with the connector 400, the position of the locking pin 320 can be controlled more precisely, ensuring its accuracy and stability during installation. The design of the connector 400 rotating circumferentially around the body 100 and being installed in the limiting groove 101 makes the connection process more convenient and efficient, while providing a reliable connection and fixing method to prevent the connector 400 from loosening or falling off. This design improves the assembly efficiency and quality of the entire fluid connector locking structure, ensuring its reliability and safety in actual use. Furthermore, the connector 400 is provided with an extension groove 401. After the connector 400 is rotated and installed in place, the locking pin 320 moves outward and extends into the extension groove 401, driving the locking pin 320 and the locking ball 230 into a second mating position. This design cleverly combines the installation of the connector 400 with the position adjustment of the locking pin 320, achieving automatic adjustment of the locking pin 320 to the appropriate working position while the connector 400 is installed. The extension groove 401 provides accurate positioning and guidance for the locking pin 320, ensuring that it can smoothly enter and be in the second mating position with the locking ball 230, thereby ensuring that the subsequent rotating handle 210 can rotate normally to operate the ball valve. This integrated design improves the automation level and ease of operation of the entire structure, reduces the workload of manual intervention and adjustment, improves work efficiency, and also enhances the reliability and stability of the locking structure, ensuring the normal operation of the fluid conveying system.

[0051] Refer to Figures 5 to 7In some embodiments of this utility model, a control element 130 is also included. The locking pin 320 is provided with a control hole 3204, and the body 100 is provided with a control groove 102. The control groove 102 extends along an axial direction parallel to the locking pin 320. The control element 130 can be inserted into the control groove 102 and the control hole 3204 in sequence to drive the locking pin 320 to move axially and to switch the locking pin 320 between a first mating position, a second mating position, and a third mating position. This provides users with an intuitive and convenient way to control the position switching of the locking pin 320. By inserting the control element 130 into the control groove 102 and the control hole 3204, the operator can easily control the axial movement of the locking pin 320, thereby flexibly adjusting the rotation state of the rotating handle 210 according to actual needs. This design improves the convenience and accuracy of operation, enabling operators to quickly and accurately operate the fluid connector locking structure according to different working scenarios, further enhancing the operability and safety of the entire fluid conveying system. For example, when there is no connector 400 or the connector 400 is not of suitable specifications and therefore does not have an extension slot 401, the user can actively operate the locking pin 320 by operating the control element 130 to directly control the locked or unlocked state of the rotating handle 210. It should be noted that the control element 130 generally functions as a manual emergency switch; for example, when the rotating handle 210 is turned to… Figure 3 In the corresponding position, move the control element 130 to the first engagement position so that the locking pin 320 can be rotated to disengage from the ball valve connector of a different model, that is, to disengage from the incompletely matched connector 400.

[0052] The control valve assembly according to an embodiment of the present invention includes a fluid connector locking structure according to an embodiment of the present invention. The optimized fluid connector locking structure, applied to the control valve assembly, enables the control valve assembly to possess superior performance and reliability. Specifically, the fluid connector locking structure can precisely control the rotation of the ball valve core, preventing accidental fluid leakage under various operating conditions and ensuring the sealing and stability of the control valve assembly. Simultaneously, its flexible operation and reliable locking mechanism make the control valve assembly smoother and more accurate during opening and closing, improving the control precision and efficiency of fluid delivery. This integrated design enhances the practicality and competitiveness of the entire control valve assembly, meeting the stringent requirements of fluid delivery systems in different industrial scenarios and laying a solid foundation for the safe and efficient operation of fluid delivery systems.

[0053] Other configurations and operations of the control valve assembly according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0054] Refer to Figures 9 to 11The fluid connector locking structure, according to another embodiment of this utility model, includes two connectors 500 that can be rotatably mounted in opposite directions, two control components corresponding to each connector 500, and two telescopic components 300 corresponding to each connector 500. Each control component includes a rotary handle 210, a ball valve core, and a locking ball 230. The rotary handle 210 rotates to open and close the ball valve core, and a locking groove 2101 is provided on the outer peripheral wall of the rotary handle 210. Each telescopic component 300 includes a compression spring 310 and a locking pin 320. The locking pin 320 has a first mating position, a second mating position, and a third mating position with the locking ball 230 along its axial direction. Referring to the above... Figures 1 to 8 The relevant description states that the main body 100 is a part of the main body 100 of the connector 500. The connection relationship and function of the rotating handle 210, ball valve core, locking ball 230, compression spring 310 and locking pin 320 can be referred to. Figures 1 to 8 The relevant descriptions are not detailed here. It should be noted that the precise engagement between the locking pin 320, locking ball 230, and rotating handle 210 effectively prevents the rotating handle 210 from rotating when the connector 500 is not fully installed, thus preventing fluid leakage and greatly improving the system's sealing and safety. Simultaneously, its unique telescopic component 300 design allows the locking pin 320 to achieve precise locking and unlocking in different positions, ensuring the stability and reliability of the connector 500 under various conditions. For example, when the locking pin 320 is in the first mating position as usual, or when the locking pin 320 is simply fully pressed into the third mating position (if not fully installed or incorrectly installed), the locking pin 320 can drive the locking ball 230 into the locking groove 2101 on the outer peripheral wall of the rotary handle 210. This effectively prevents the rotary handle 210 from rotating counterclockwise to open the ball valve, preventing accidental fluid leakage due to misoperation of the rotary handle 210. This ensures that fluid will not flow out due to improper operation when the ball valve connector 500 is in the closed state or not properly connected, thus guaranteeing the safety and stability of the fluid delivery system. Furthermore, when the locking pin 320 is in the second mating position as normally installed and used, the locking ball 230 can disengage from the locking groove 2101, allowing the rotary handle 210 to rotate smoothly, thereby realizing the normal opening and closing operation of the ball valve. In addition, this structure simplifies the operation steps, and the installation action of the two connectors 500 can be used to switch the locking pin 320 to normal function, thereby improving the efficiency of installation and use.

[0055] It is easy to understand that, Figures 1 to 8 The corresponding connector 400 is corresponding to Figure 9 Another connector 500 in the process. Further, as... Figure 10 and Figure 11As shown, the two connectors 500 are equipped with mutually cooperating hooks 510 and slots 501 at their opposing rotational mounting points. When the two connectors 500 rotate relative to each other in the circumferential direction, the hooks 510 can be rotatably mounted in the slots 501, providing precise guidance for the opposing rotational mounting of the connectors 500. This allows the two connectors 500 to be more accurately aligned and fitted during installation, reducing deviations and errors during installation and improving installation accuracy and efficiency. Secondly, this mating structure enhances the stability and reliability of the connector connection. After the hooks 510 are engaged in the slots 501, they can effectively prevent relative displacement or loosening of the connectors 500 during operation, ensuring stability and safety during long-term operation. In addition, the mating method of the hooks 510 and slots 501 also has a certain self-locking function, which can resist external vibrations and impacts to a certain extent, further ensuring the stable operation of the fluid conveying system.

[0056] Furthermore, in some embodiments of this utility model, guide groove walls 502 are provided on the opposite end faces of the two connectors 500 to guide the locking pin 320 into or out of the extension groove 401. On the one hand, this ensures that the locking pin 320 moves along a predetermined trajectory during its entry into or exit from the extension groove 401, preventing the locking pin 320 from deviating or getting stuck during movement, thus improving the accuracy and smoothness of the locking pin 320's movement. On the other hand, the guide groove walls 502 also provide a certain degree of protection for the locking pin 320, preventing it from being subjected to external impacts or damage during movement, thereby extending the service life of the locking pin 320. In addition, the cooperative design of the guide groove walls 502 and the extension groove 401 makes the entire installation and disassembly process of the connector 500 smoother and more convenient, improving operational efficiency and reliability, and further ensuring stable operation under different working conditions.

[0057] Refer to Figure 9 and Figure 11In some embodiments of this utility model, dustproof rings 520 are provided at the opposite locations of the two connectors 500 to seal the periphery of the opposite locations of the two connectors 500, providing a significant dustproof and sealing effect after connection. Firstly, the dustproof rings 520 effectively prevent dust, impurities, etc., from entering the connection points of the two connectors 500, avoiding interference with the normal operation of the connectors 500, reducing wear and jamming caused by foreign objects, and extending the service life of the connectors 500. Secondly, the dustproof rings 520 also play a certain sealing role, preventing fluid leakage at the connection points of the connectors 500, ensuring the sealing and stability of the fluid transport system. In some applications with high requirements for fluid transport accuracy and safety, this dustproof and sealing design is particularly important, ensuring accurate fluid transport, avoiding resource waste and environmental pollution, and also improving the safety and reliability of the entire fluid transport system.

[0058] Refer to Figure 12 According to the usage method of this utility model embodiment, when applied to the fluid connector locking structure as described above, the usage method includes the following steps during installation:
