[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a copper joint with high sealing performance.

[0025] As Figures 1-4 shown, it includes an external hexagonal nut 1. A threaded groove 2 is provided in the middle of the outer surface of the upper end of the external hexagonal nut 1. An external threaded column 3 is fixedly installed in the middle of the outer surface of the lower end of the external hexagonal nut 1. Anti-loosening and sealing components 4 are arranged at both the upper and lower ends of the external hexagonal nut 1. The anti-loosening and sealing component 4 includes a guide hole 7, an annular installation groove 8, an annular block 9, a guide rod 10, a compression spring 11, an annular groove 12 and a third sealing ring 13. The number of anti-loosening and sealing components 4 is two groups. The annular installation groove 8 is opened on the outer surfaces of both the upper and lower ends of the external hexagonal nut 1, and the guide hole 7 is opened at one end of the annular installation groove 8.

[0026] A second sealing ring 6 is installed at one end of the inner cavity of the external hexagonal nut 1 close to the external threaded column 3; a first sealing ring 5 is adhesively bonded to the outer surface of the end of the external threaded column 3 away from the external hexagonal nut 1; both the compression spring 11 and the guide rod 10 are located in the annular installation groove 8. One end of the guide rod 10 extends into the guide hole 7, and one end of the annular block 9 extends into the annular installation groove 8; the annular groove 12 is opened on the outer surface of the upper end of the annular block 9, and one side of the third sealing ring 13 is fixedly installed in the annular groove 12. The guide rod 10 is fixedly installed on the outer surface of the side of the annular block 9 away from the annular groove 12. The compression spring 11 is movably sleeved on the outer wall of the guide rod 10. One end of the outer surface of the compression spring 11 is fixedly connected to one side of the outer surface of the annular block 9, and the other end of the outer surface of the compression spring 11 is fixedly connected to one end of the annular installation groove 8; the outer wall of the annular block 9 is slidably connected to the annular installation groove 8, the outer wall of the guide rod 10 is slidably connected to the guide hole 7, and one end of the outer surface of the annular block 9 is elastically connected to one end of the annular installation groove 8 through the compression spring 11.

[0027] It should be noted that for this copper joint with high sealing performance of the present utility model, with the anti-loosening and sealing component 4 provided, after the copper joint is threadedly connected to the two pipes to be connected, the third sealing ring 13 is squeezed. The third sealing ring 13 drives the annular block 9 to squeeze the compression spring 11 in the annular installation groove 8. The annular block 9 drives the guide rod 10 to slide along the guide hole 7. Through the provided annular groove 12, the annular groove 12 can limit the third sealing ring 13 to improve the stability of the third sealing ring 13.
