DETAILED DESCRIPTION OF THE EMBODIMENTS
[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 Bundy tube joint with a wide application range.
[0025] Such as Figures 1-4As shown in the figure, it includes a joint 1. An external thread 2 is provided on the outer wall of the joint 1. A hexagonal nut 3 is fixedly installed on the outer surface of the upper end of the joint 1. An internal thread 4 is provided inside the hexagonal nut 3. An anti-loosening structure 5 is arranged at the bottom of the hexagonal nut 3. The anti-loosening structure 5 includes an annular installation cavity 6, a compression spring 7, a limiting block 8, a through hole 9, a movable rod 10, an installation groove 11 and a ball 12. The annular installation cavity 6 is opened inside the hexagonal nut 3.
[0026] The number of the through hole 9, the movable rod 10, the installation groove 11 and the ball 12 are all two groups. The limiting block 8 and the compression spring 7 are both located in the annular installation cavity 6. The movable rod 10 penetrates through the through hole 9. The two through holes 9 are opened on the left and right sides of the outer surface of the lower end of the hexagonal nut 3, and the upper ends of the two through holes 9 communicate with the annular installation cavity 6. The lower outer surface of the compression spring 7 is fixedly connected to the upper outer surface of the limiting block 8. The upper outer surface of the compression spring 7 is fixedly connected to the top of the annular installation cavity 6. The movable rod 10 is fixedly installed in the middle of the lower outer surface of the limiting block 8. The installation groove 11 is opened on the lower outer surface of the movable rod 10. The ball 12 is rotatably connected in the installation groove 11. The outer wall of the limiting block 8 is slidably connected with the annular installation cavity 6. The outer wall of the movable rod 10 is slidably connected with the through hole 9. The upper outer surface of the limiting block 8 is elastically connected to the upper end of the annular installation cavity 6 through the compression spring 7.
[0027] It should be noted that the present utility model is a Bundy pipe joint with a wide range of applications. The joint 1 externally connects to a Bundy pipe through the external thread 2. The anti-loosening structure 5 is arranged at the bottom of the hexagonal nut 3. When the joint 1 externally connects to a Bundy pipe through the external thread 2, the ball 12 at one end of the movable rod 10 is squeezed, driving the movable rod 10 to slide along the through hole 9. The movable rod 10 drives the limiting block 8 to squeeze the compression spring 7 in the annular installation cavity 6. When rotating the hexagonal nut 3, through the provided ball 12, the ball 12 can rotate in the installation groove 11, which can reduce the resistance during rotation. After the joint 1 externally connects to a Bundy pipe through the external thread 2, the compression spring 7 in the annular installation cavity 6 is in a squeezed state, providing a pre-tightening force in the compressed state, which can help maintain the position of the external thread 2 and prevent it from loosening by itself, thereby increasing the application range of the Bundy pipe joint.
