[0025] It should be noted that it achieves the effect of quickly connecting the first connecting pipe 2 and the second connecting pipe 14, thereby increasing the connection efficiency of the first connecting pipe 2 and the second connecting pipe 14.

[0026] Please refer to Figures 1-3, in this embodiment, the limiting component includes a cabin body 9 fixedly connected to the movable block 7. A limiting rod 10 is slidably connected inside the cabin body 9. A handle 19 convenient for pulling is fixedly connected to the limiting rod 10.

A limiting plate 12 is fixedly connected to the outside of the limiting rod 10, and one side of the limiting spring 11 is fixedly connected to one side of the limiting plate 12.

[0027] It should be noted that it is also convenient to squeeze the gasket 17 to increase the sealing performance after the sleeve 1 and the connecting block 13 are connected.

[0028] Please refer to Figures 1-3 , in this embodiment, the connecting component includes a connecting block 13 slidably connected to the right side of the sleeve 1. A limiting groove is formed in the connecting block 13, and the size of the limiting groove is adapted to the size of the limiting rod 10.

[0030] The working principle of the above embodiment is as follows: for this contact type corrosion-resistant quick connector,

[0031] 1) When in use, pull the two handles 19 away from each other. The two handles 19 drive the two limiting rods 10 to move away from each other and contract into the interior of the cabin body 9. At the same time, the limiting plate 12 squeezes the limiting spring 11. Then insert the fixed pipe 15 on the connecting block 13 into the interior of the sleeve 1, so that the right side of the sleeve 1 contacts the left side of the gasket 17 provided on the left side of the connecting block 13.

[0032] 2) Then release the handle 19. The two limiting rods 10 move relative to each other and insert into the limiting grooves formed in the connecting block 13 through the reset of the limiting spring 11, so that the sleeve 1 and the connecting block 13 are quickly connected. Then rotate the rotary handle 18. The rotary handle 18 drives the worm 4 to rotate. The worm 4 drives the worm wheel 6 to rotate. The worm wheel 6 drives the threaded rod 5 to rotate. The threaded rod 5 drives the movable block 7 to move leftward. By setting the support block 8 and the support groove, the stability of the movable block 7 during movement is increased, so as to pull the limiting rod 10, and further the connecting block 13 squeezes the gasket 17.

[0033] 3) By setting the worm 4 and the worm wheel 6, the limiting mechanism has self-locking property, which increases the stability after the sleeve 1 is connected to the connecting block 13, thus achieving the effect of rapid connection between the first connecting pipe 2 and the second connecting pipe 14, thereby increasing the connection efficiency of the first connecting pipe 2 and the second connecting pipe 14. At the same time, it is also convenient to squeeze the sealing gasket 17 to increase the sealing performance after the sleeve 1 is connected to the connecting block 13, which is convenient for the user and increases the practicability of the quick connector.
