[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a one-time connection quick connector structure, including pipe 1 and pipe 2 4, a cavity 10 is provided inside pipe 1, and the cavity 10 is the activity space of the ball 7, which can provide sufficient space for the operation of the locking component, and a sealing component is provided inside pipe 1, and the sealing component is used to ensure that the medium does not leak when the pipes are connected, thereby improving the sealing of the joint structure. A card slot 5 is provided inside pipe 2 4, and the card slot 5 is used to be embedded and fixed with the ball 7. Pipe 2 4 is slidably connected inside pipe 1, and the sliding connection ensures that pipe 2 4 can be smoothly inserted into or pulled out of pipe 1, thereby improving the convenience of joint connection and disassembly. A locking component is provided inside pipe 1, and the locking component is used to quickly complete the fixing operation of the pipe. A reset component is provided on the outer wall of pipe 1, and the reset component can automatically reset the locking component after being released, thereby ensuring the smoothness of the joint operation;

[0032] The locking assembly includes a disassembly sleeve 2, which is slidably connected to the outer wall of Pipe 1 and can slide axially along the outer wall of Pipe 1 to activate locking and unlocking operations. A retaining ring 3 is fixedly connected to the interior of the disassembly sleeve 2. The retaining ring 3 cooperates with the ball 7 during the sliding process to retain or release the ball 7, enhancing the reliability of the locking assembly. A ball 7 is positioned within Pipe 1 and slidably connected to the interior of the cavity 10. During its movement, the ball 7 engages with the retaining groove 5 to complete the locking operation. The sealing assembly includes a sealing ring 8, the outer wall of which is fixedly connected to Pipe 1, providing a circumferential seal when Pipe 2 4 is inserted. The inner wall of the sealing ring 8 mates with the outer wall of Pipe 2 4, ensuring a tight seal between the two pipes. The reset assembly includes a first spring 9, which is mounted on the outer wall of Pipe 1 and provides the necessary elastic force for the reset operation. One end of the first spring 9 is fixedly connected to the bottom of the retaining ring 3. The elastic force acts to reset the retaining ring 3 upward after the disassembly sleeve 2 is released. The other end of the first spring 9 is fixedly connected to the inside of the pipe 1, ensuring that the spring position is stable and the reset action is reliable, thereby improving the operating efficiency and stability of the entire quick connector structure;

[0033] Specifically, when connecting pipe 1 and pipe 2 4, the removal sleeve 2 is first moved downward, driving the retaining ring 3 downward with it, disengaging the retaining ring 3 from contact with the ball 7, thereby allowing the ball 7 to move flexibly within the cavity 10. However, to ensure that the ball 7 does not slip out of the cavity 10, its range of motion is effectively limited by the structure of the cavity 10. Next, the lower end of pipe 2 4 is inserted into pipe 1 1 and secured in place. When the removal sleeve 2 is released, the retaining ring 3 quickly returns to its original position under the tension provided by the first spring 9 and compresses the ball 7, firmly embedding it in the retaining groove 5 on pipe 2 4, thus firmly locking the two pipes 1 and 2 4. Simultaneously, the sealing ring 1 8 provides a reliable seal in the connection area between pipe 1 and pipe 2 4, preventing medium leakage. Through this series of operations, a quick, convenient, and secure connection between pipe 1 and pipe 2 4 is achieved, significantly improving operational efficiency and connection stability.

[0034] Reference Figure 3 A fixed column 11 is fixedly connected to the inside of pipe 1. The fixed column 11 is used to support and limit the internal sealing and movable parts. A through hole 12 is opened inside the fixed column 11. The through hole 12 is used for the circulation of liquid media to ensure that the medium can pass smoothly when pipe 1 and pipe 2 4 are connected, thereby improving the practicality of the joint. A top column 15 is slidably connected to the inside of the fixed column 11. The top column 15 can slide axially inside the fixed column 11, and complete the opening and closing function of the sealing ring 2 16 through the sliding action, thereby realizing the sealing or unsealing operation. A baffle 2 14 is fixedly connected to the bottom of the top column 15. The baffle 2 14 can limit and stabilize the top column 15. At the same time, when pipe 2 4 is connected or separated from pipe 1, it cooperates with the baffle 1 6 to complete the pushing or resetting operation of the top column 15. A baffle 16 is fixedly connected to the inside of pipe 24, and the bottom of baffle 16 fits on the top of the top column 15. When pipe 24 is inserted or pulled out, baffle 16 can come into contact with the top column 15 and exert force, thereby driving the top column 15 to move and complete the opening and closing control of the through hole 12. A sealing ring 216 is fixedly connected to the outer wall of the top column 15, and the outer wall of the sealing ring 216 fits on the inner wall of the fixed column 11, which is used to provide an effective sealing function when pipe 24 is separated from pipe 11, avoiding liquid leakage and ensuring the safety and reliability of the joint. A limit plate 13 is fixedly connected to the outer wall of the top column 15, and the limit plate 13 can limit the sliding range of the top column 15 to ensure the accuracy of the sealing action. A second spring 17 is provided on the outer wall of the limit plate 13, and the second spring 17 is used to provide a reset force so that the top column 15 can automatically reset after the baffle 16 is separated, thereby improving the convenience and efficiency of operation. One end of the second spring 17 is fixedly connected to the bottom of the limit plate 13, and through the elastic force, it pushes the limit plate 13 to move into the fixed column 11. The other end of the second spring 17 is fixedly connected to the inside of the fixed column 11, ensuring the stable position of the spring and the reliable reset action, thereby improving the operational stability of the entire quick connector structure;

[0035] Specifically, when pipe 2 4 is connected, the baffle 1 6 inside it first contacts the top column 15 and applies pressure to push the top column 15 to move, thereby driving the sealing ring 2 16 to separate from the inner wall of the fixed column 11. In this process, the sealing state formed between the sealing ring 2 16 and the fixed column 11 is released, and the liquid can flow smoothly through the through hole 12, ensuring unimpeded transmission of the liquid. Correspondingly, when pipe 2 4 is separated from pipe 1, the top column 15 is separated from the baffle 1 6. Under the tension of the second spring 17, the top column 15 quickly pushes the limit plate 13 back to the initial position, and at the same time drives the sealing ring 2 16 to reset and fit on the inner wall of the fixed column 11, thereby re-forming a sealing state and effectively preventing liquid leakage. Through this design, an automatic sealing effect is achieved after the pipes are separated, ensuring that the system still has good safety and sealing after unlocking, while simplifying the operating process and improving the applicability and convenience of the equipment.

[0036] Working principle: When using the one-time quick connector structure, first connect pipe 1 and pipe 2 4, then move the disassembly sleeve 2 to drive the fixing ring 3 downward, so that the fixing ring 3 and the ball 7 are separated, so that the ball 7 can move in the cavity 10, but the ball 7 will not slip in the cavity 10, then insert pipe 2 4 into pipe 1, and when the disassembly sleeve 2 is released, the fixing ring 3 is driven to reset by the tension of the first spring 9, and presses against the ball 7 so that the ball 7 is embedded in the slot 5 on pipe 2 4 to lock it, and pipe 2 4 and pipe 1 1 are connected. The sealing is performed by the sealing ring 18, so as to achieve the effect of quickly connecting the pipe 1 and the pipe 2 4. When the pipe 2 4 is connected, the internal baffle 16 is pressed against the top column 15 to drive the sealing ring 2 16 to separate from the fixed column 11, thereby allowing the liquid to flow through the through hole 12. When the pipe 2 4 is separated from the pipe 1, the top column 15 is separated from the baffle 16, so that the top column 15 pushes the limit plate 13 to return to its original position through the tension of the second spring 17, thereby driving the sealing ring 2 16 to return to its original position and fit the inner wall of the fixed column 11 for sealing, thereby achieving the effect of self-sealing after unlocking.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
