[0025] The lock structure includes an unlocking rotating ring 13 rotatably mounted on the outside of the connecting seat 11, and a plurality of driving inclined grooves 14 are opened on the inner side of the unlocking rotating ring 13. A driving block 2 17 is slidably installed at the side of the locking block slot 20 in the connecting seat 11. The tail of the driving block 2 17 is arranged directly opposite the locking block slot 20, and the head of the driving block 2 17 is a sloped surface. A driving slide 15 is opened at the head of the driving block 2 17 in the connecting seat 11. A driving block 16 is slidably installed in the driving slide 15. The driving block 16 is arranged perpendicular to the driving block 2 17. The bottom end of the driving block 16 is an inclined surface matching the head of the driving block 2 17, and the top of the driving block 16 is an inclined surface. A driving inclined groove 14 matching the shape of the top of the driving block 16 is opened in the unlocking rotating ring 13, and the top of the driving block 16 is arranged in the driving inclined groove 14;

[0026] The side of the second driving block 17 is connected to the limiting block 18. A limiting slot 19 is provided in the connecting seat 11 on the side of the second driving block 17.

[0028] The principle and use process of this utility model:

[0029] When connection is required, hold the composite tube 1 and the composite tube 2 2 so that the connecting plug 4 is aligned with the mouth of the connecting seat 11 and inserted, and at the same time, the guide rib 5 is inserted into the guide groove 12. Since the outer side of the movable locking block 7 is inclined, it can be squeezed inward by the guide groove 12 as the guide rib 5 is inserted, and retracted into the movable groove 6. At the same time, the spring 10 is compressed until the movable locking block 7 is aligned with the locking block slot 20. The movable locking block 7 can be ejected under the action of the spring 10 and enter the locking block slot 20, thereby connecting the connecting plug 4 to the connecting seat 11. The movable slider 9 serves as a limiter to prevent the movable locking block 7 from excessive movement.

[0030] At the same time, the torsion spring pulls the unlocking rotating ring 13, as shown in FIG. Figure 4 In the state shown, the unlocking rotating ring 13 is pulled and tightened in the clockwise direction. Figure 5 As shown, the return spring 21 pushes the driving block 2 17 to the left, and the slope at the front end of the driving block 2 17 pushes the driving block 1 16 upward, so that the top end of the driving block 16 is stuck in the driving inclined slot 14;

[0031] When unlocking is required, the unlocking rotating ring 13 is rotated counterclockwise to push the driving block 16 downward through the driving inclined groove 14, and then the driving block 2 17 is pushed backward through the driving block 16. The driving block 2 17 slides out from the inner side of the locking block slot 20, pushing the movable locking block 7 to retract it into the movable slot 6, and the connecting plug 4 and the connecting seat 11 can be separated, that is, the composite tube 1 1 and the composite tube 2 2 are separated, and the reset spring 21 pushes the driving block 2 17 to automatically reset.
