[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] First embodiment:

[0025] See also Figure 1-Figure 3 As shown, the present invention provides a composite pipe connection structure, comprising an interface connector 3 detachably connected to the movable ends of pipe 1 and pipe 2, and a connecting ring 4 located between the two interface connectors 3, the connecting ring 4 being detachably connected to the interface connector 3; a sealing ring 5 is provided on the connecting ring 4 for sealing with the interface connector 3;

[0026] The interface connector 3 is located at the movable ends of pipe 1 and pipe 2, and cooperates with the connecting ring 4 in a detachable manner to achieve a stable connection of the pipes. The connecting ring 4 provides effective connection support between the two interface connectors 3. The sealing ring 5 on the connecting ring 4 further enhances the sealing performance of the connection and prevents liquid or gas from leaking at the connection. When maintenance or replacement of the pipe is required, it can be easily disassembled and reconnected, which improves the flexibility and maintainability of the system.

[0027] This device makes the pipeline system more convenient during installation and maintenance, reducing time and labor costs; secondly, the sealing ring 5 at the connection point of the pipeline has a better sealing effect, which can effectively prevent the leakage of liquid or gas and ensure the normal operation and safety of the system; and the detachable connection function of the interface connector 3 and the connecting ring 4 increases the flexibility and maintainability of the pipeline system, and can adapt to different usage requirements and environmental changes, thereby extending the service life of the system and improving the overall efficiency. This device optimizes the connection method of the pipeline system and brings higher safety and reliability.

[0028] Pipe 1 and Pipe 2 are both connected to the interface connector 3 through the same structure. The interface connector 3 includes a pipe body frame 301, on which an inner pipe 303 extending into the interior of pipe 1 is provided, and further includes a connecting sleeve 304 and a sealing ring 305 located on the outside of pipe 1. The sealing ring 305 is located on the inside of the connecting sleeve 304, and the connecting sleeve 304 is threadedly connected to the pipe body frame 301. The interface connector 3 includes a pipe body frame 301, an inner pipe 303, a connecting sleeve 304 and a sealing ring 305. The pipe body frame 301 constitutes the main body of the interface connector, and the inner pipe 303 is provided on the connecting sleeve 304. 3 extends into the interior of pipe 1, ensuring a close connection between the fluid inside the pipe and the connector. Furthermore, a sealing ring is provided on the outside of the inner pipe 303 to seal with the inner walls of pipe 1 and pipe 2, and the connecting sleeve 304 is connected to the pipe body frame 301 through a threaded connection, forming a stable mechanical connection. The threaded connection enables the connecting sleeve 304 to be firmly matched with the pipe body frame 301, ensuring a stable connection between pipe 1 and the interface connector 3. This stable connection method effectively prevents the loosening of the pipeline due to vibration or pressure changes, and provides reliable support and stability.

[0029] In the overall structure of the device, the sealing ring 305 is located on the inner side of the connecting sleeve 304 and directly contacts the outer wall of pipe 1. Its function is to form a sealed isolation layer to prevent fluid leakage. The presence of the sealing ring greatly improves the sealing of the outer walls of pipe 1 and pipe 2, ensuring that the pipeline system does not leak during operation, thereby improving the safety and reliability of the system.

[0030] The movable end of the pipe frame 301 is connected to a flange, which is provided with a plurality of blind holes. The connecting ring 4 includes a set 401 and a retaining ring 402 provided on both sides of the set 401. The retaining ring 402 is rotatably connected to a broken line rod 403. The movable end of the broken line rod 403 is threadedly connected to a bolt 404 corresponding to the blind hole.

[0031] The threaded end of the broken line rod 403 cooperates with the blind hole on the flange, and the fastening of the bolt 404 ensures the firmness of the connection, allowing a strong and adjustable connection structure to be formed between the flange and the connecting ring 4. The design of the blind hole allows the connecting ring 4 to be easily docked with the flange without interfering with the overall structure of the pipeline system, thereby improving the overall adaptability and reliability of the system.

[0032] The second embodiment is different from the first embodiment in that:

[0033] Both sides of the sealing ring 5 are conical, and the movable end of the pipe body frame 301 is provided with a conical groove 1, and the sealing ring 5 cooperates with the conical groove 1.

[0034] The kit 401 extends in a straight line, and the sealing ring 5 is movably installed inside the kit 401. The sealing ring 5 is a single piece, and its two ends respectively cooperate with the movable end of the pipe body frame 301; both sides of the sealing ring 5 are provided with a tapered surface, which accurately cooperates with the tapered groove on the movable end of the pipe body frame 301. The kit 401 extends in a straight line structure, and the sealing ring 5 is movably installed inside the kit 401. The sealing ring 5 is a single piece in this structure, and its two ends respectively cooperate with the movable end of the pipe body frame 301, and the excellent sealing performance of the tapered cooperation is used to ensure that the pipeline system is tightly sealed at the connection.

[0035] The third embodiment is different from the second embodiment in that:

[0036] The middle part of the kit 401 is a concave structure, and a through hole corresponding to the pipe 1 is provided inside the kit 401. The end of the retaining ring 402 away from the kit 401 is provided with a conical groove 2. There are two sealing rings 5, and the two ends are respectively arranged corresponding to the conical groove 1 and the conical groove 2. The kit 401 with the concave structure can reduce the thickness of the sealing ring 5. The two sealing rings 5 are respectively installed on both sides of the connecting ring 4, and the sealing ring 5 is used to seal between the retaining ring 402 and the pipe body frame 301; in this design, the concave structure in the middle part of the kit 401 optimizes the thickness of the sealing ring 5, so that the sealing ring 5 can fit more closely with the interface between the retaining ring 402 and the pipe body frame 301, and the through hole inside the kit 401 is docked with the pipe 1 to achieve a precise connection; the two ends of the sealing ring 5 are respectively matched with the conical groove 1 and the conical groove 2, forming an efficient sealing interface on both sides of the connecting ring 4, reducing the risk of leakage caused by insufficient thickness of the sealing ring. The concave structure not only reduces the thickness of the sealing ring 5, but also improves the adaptability of the sealing ring, so that the connection part can better cope with environmental changes and system loads.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
