[0032] A kind of corrosion-resistant double closed plastic quick connector, such as Figures 1 to 4 , comprising: middle connector 1;Two sides of middle connector 1 are provided with mounting mechanism 2, and the upper side of middle connector 1 is provided with double closed mechanism 3, mounting mechanism 2 includes internal thread 21, and internal thread 21 is divided into the inner side of both ends of middle connector 1, both ends of middle connector 1 are provided with side connector 22, and the outer side of one end of side connector 22 is divided into first external thread 23, conveying connector 24 is fixedly arranged in the middle part of the outer end of side connector 22, and second external thread 25 is arranged on the peripheral outer side of conveying connector 24, the first external thread 23 arranged on the outer side of side connector 22 is connected with the internal thread 21 arranged on the inner side of both ends of middle connector 1 by thread, and the first external thread 23 corresponding to the thread structure of internal thread 21 can be used by construction personnel to detach the side connector 22 needed to be detached from the corresponding end of middle connector 1, so as to achieve the effect of portable disassembly.

[0033] The double sealing mechanism 3 comprises an outer frame 31, which is fixed to the upper part of the middle connector 1. A sealing assembly 32 is installed in the middle connector 1 and the inner and outer parts of the outer frame 31. The sealing assembly 32 comprises a rotating rod 321, which is installed in the middle part of the middle connector 1 and the outer frame 31. One end of the rotating rod 321 is connected with a hand wheel 322. A valve plate 323 is fixed to the periphery of one section of the rotating rod 321. Limiting stop plates 324 are fixed to the different sides of the inner part of the middle connector 1. Rubber sealing pads 325 are fixed to the opposite surfaces of the limiting stop plates 324 and the valve plate 323. The limiting stop plates 324 are separately arranged on the different sides of the inner part of the middle connector 1. The opposite sides of the two limiting stop plates 324 are attached with rubber sealing pads 325. A locking assembly 33 is installed on the inner and outer parts of one side of the outer frame 31. The locking assembly 33 comprises a partition plate 331, which is fixed to the inner upper part of the outer frame 31. A gear 332 is fixed to the upper periphery of the rotating rod 321. A guide groove frame 333 is fixed to the upper side of the partition plate 331. A guide frame 334 is arranged in the inner part and the upper part of the guide groove frame 333. The guide groove frame 333 and the guide frame 334 are movably connected. A clamping block 335 is fixed to the inner side of the guide frame 334. Reset springs 336 are separately arranged on the two sides of the end of the guide frame 334. A hand holding block 337 is fixed to the upper side of one side of the guide frame 334.
