Specific implementation manner

[0021] As Figures 1-4 shown, the utility model provides a technical solution: a tubing coupling capable of preventing detachment, including a coupling body 1, a guiding component 2 is arranged on the coupling body 1 to facilitate alignment of the tubing and the coupling body 1, and a positioning component 3 for pressing the tubing is arranged on the coupling body 1.

[0022] Specifically, the guiding component 2 includes a groove 21, a connecting spring 23, a moving ring 22, a guiding rod 24, a transmission block 25, a movable rod 26 and a guiding wheel 27; the groove 21 is opened on the outer wall of the coupling body 1, and a moving ring 22 is slidably installed on the inner wall of the groove 21. By providing the groove 21, it can play a role in guiding the moving ring 22. A connecting spring 23 is fixed on the side wall of the moving ring 22, and the side of the connecting spring 23 away from the moving ring 22 is fixed on the inner wall of the groove 21. By providing the connecting spring 23, it can play an effect of resetting the moving ring 22. A guiding rod 24 is fixed on the outer wall of the coupling body 1, and a transmission block 25 is slidably installed on the outer wall of the guiding rod 24. There are four groups of transmission blocks 25, and they are arranged in a circumferential array with the center point of the moving ring 22 as the center. By providing the guiding rod 24, it can play a role in guiding the transmission block 25. The side wall of the transmission block 25 is hinged with a movable rod 26, and one end of the movable rod 26 away from the transmission block 25 is hinged on the outer wall of the moving ring 22. When the tubing needs to be connected, the moving ring 22 is pushed close to the guiding rod 24, so that the connecting spring 23 is stretched, and the moving ring 22 squeezes the movable rod 26, causing the movable rod 26 to rotate at the hinge, and the movable rod 26 squeezes the transmission block 25 to move on the guiding rod 24, so that the four groups of transmission blocks 25 move away from each other. A guiding wheel 27 is fixed on the inner side of the transmission block 25. When the four groups of transmission blocks 25 move away from each other, it can drive the four groups of guiding wheels 27 to move away from each other, and then the tubing can be placed between the four groups of guiding wheels 27. By releasing the moving ring 22, because the connecting spring 23 is in a stretched state, the moving ring 22 moves away from the guiding rod 24, pulls the movable rod 26, makes the four groups of transmission blocks 25 move closer to each other, and makes the guiding wheel 27 squeeze and position the tubing, so that the tubing is aligned with the coupling body 1, which is convenient for screwing the tubing into the coupling body 1, preventing the tubing from shifting during screwing, causing the thread to slip, affecting the connection stability and being prone to loosening.

[0023] Specifically, the positioning component 3 includes a support block 31, a threaded rod 32, a rotating block 33, a pressing plate 34, a sleeve 35 and a sleeve rod 36; the support block 31 is fixed on the side wall of the coupling body 1, and the threaded rod 32 passes through the support block 31 and is threadedly connected at the passing position. The threaded rod 32 passes through the transmission block 25, and a rotating block 33 is fixed at one end of the threaded rod 32 away from the support block 31. When the rotating block 33 is rotated forward, the threaded rod 32 can move while rotating. A pressing plate 34 is rotatably installed at one end of the threaded rod 32 away from the rotating block 33. The pressing plate 34 is made of rubber. When the threaded rod 32 moves downward, it drives the pressing plate 34 away from the transmission block 25. A sleeve 35 is fixed on one side of the support block 31 away from the pressing plate 34. A sleeve rod 36 is slidably installed on the inner wall of the sleeve 35, and the end point of the sleeve rod 36 is fixedly connected to the outer wall of the pressing plate 34. By providing the sleeve 35 and the sleeve rod 36, the pressing plate 34 can be guided. When the pressing plate 34 moves away from the transmission block 25, the pressing plate 34 can press and fix the oil pipe, position the oil pipe, prevent the connection between the coupling body 1 and the oil pipe from loosening and falling off.

[0024] Working principle: When the oil pipe is installed on the coupling body 1, the moving ring 22 is pushed close to the guide rod 24, the connecting spring 23 is stretched, the moving ring 22 squeezes the movable rod 26, the movable rod 26 rotates at the hinge, the movable rod 26 squeezes the transmission block 25 to move on the guide rod 24, the four groups of transmission blocks 25 move away from each other, driving the four groups of guide wheels 27 to move away from each other. Furthermore, the oil pipe can be placed between the four groups of guide wheels 27. By releasing the moving ring 22, since the connecting spring 23 is in a stretched state, the moving ring 22 moves away from the guide rod 24, pulling the movable rod 26, the four groups of transmission blocks 25 move closer to each other, the guide wheels 27 squeeze and position the oil pipe, align the oil pipe with the coupling body 1, facilitating screwing the oil pipe into the coupling body 1, preventing the oil pipe from shifting during screwing, causing the thread to slip and affecting the connection stability, and being prone to loosening.

[0025] When the oil pipe is screwed into the coupling body 1, when the rotating block 33 is rotated forward, the threaded rod 32 can move while rotating, driving the pressing plate 34 away from the transmission block 25, so that the pressing plate 34 can press and fix the oil pipe, position the oil pipe, prevent the connection between the coupling body 1 and the oil pipe from loosening and falling off.

[0026] In the above, the present invention has been generally described in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
