[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a quick-install water inlet / outlet connector, including an upper connector 1, a lower connector 2 and a water-stopping mechanism 3. The lower connector 2 is movably provided at the bottom end of the upper connector 1, the water-stopping mechanism 3 is provided inside the upper connector 1, and the installation mechanism 4 is fixedly provided inside the lower connector 2.

[0026] The water-stopping mechanism 3 includes a fixing rod 301, a fixing block 302, a limiting groove 303, a connecting rod 304, a water-stopping plate 305, and a sealing gasket 306. The fixing rod 301 is fixedly installed at the bottom of the lower connector 2, and the fixing block 302 is fixedly installed in the middle of the fixing rod 301. The limiting groove 303 is opened at the top of the fixing block 302. The connecting rod 304 is movably installed inside the upper connector 1. The connecting rod 304 is adapted to and movably connected to the limiting groove 303. The water-stopping plate 305 is fixedly installed at the top of the connecting rod 304, and the sealing gasket 306 is fixedly installed at the bottom of the water-stopping plate 305. This facilitates the prevention of water leakage caused by the lower connector 2 falling off, thus improving practicality.

[0027] The mounting mechanism 4 includes a first snap-fit ​​ring 401, a second snap-fit ​​ring 402, a connecting groove 403, a mounting groove 404, a mounting base 405, a return spring 406, a movable block 407, a connecting block 408, a groove 409, and a sealing ring 410. The bottom end of the upper connector 1 is fixedly provided with the first snap-fit ​​ring 401, and the top end of the lower connector 2 is fixedly provided with the second snap-fit ​​ring 402. The second snap-fit ​​ring 402 is movably connected to the first snap-fit ​​ring 401. The outer side of the upper connector 1 has a connecting groove 403, and the interior of the lower connector 2 has a mounting groove 404. The interior of the mounting groove 404 is fixedly provided with... There is a mounting base 405, and a return spring 406 is fixedly installed inside the mounting base 405. A movable block 407 is fixedly installed in the middle of the return spring 406. The movable block 407 extends to the outside of the mounting base 405. A connecting block 408 is fixedly installed in the middle of the movable block 407. The connecting block 408 is movably connected to the connecting groove 403. A groove 409 is opened at the bottom of the outer side of the upper connector 1. A sealing ring 410 is sleeved inside the groove 409. The sealing ring 410 is located inside the lower connector 2 and is movably connected, which facilitates the installation of water inlet and outlet connectors and improves work efficiency.

[0028] Working principle: When using the quick-connect inlet and outlet water connectors, the operator first installs the upper connector 1 and the lower connector 2 in the appropriate positions. The lower connector 2 is then aligned with the upper connector 1 and inserted. The locking rings 401 and 402 first enhance the stability of the lower connector 2 and the upper connector 1. During insertion, the upper connector 1 exerts pressure on the connecting block 408, causing it to retract into the mounting groove 404. Once the connecting block 408 aligns with the connecting groove 403, the pressure disappears, and the return spring 406 drives the movable block 407 and the connecting block 408 to reset and snap into the connecting groove 403, completing the installation. This ensures the stability of the installation. The sealing ring 410 improves the sealing performance of the connection between the upper connector 1 and the lower connector 2. During the insertion process, the fixing block 302 inside the lower connector 2 supports the connecting rod 304 inside the upper connector 1, causing the connecting rod 304 and the water-stop plate 305 to rise, facilitating water flow. However, when the lower connector 2 falls off, the supporting force on the connecting rod 304 disappears, and the water-stop plate 305 and the sealing gasket 306 will be pressed tightly against the upper connector 1 by the pressure of the water flow, blocking the water flow channel. The sealing gasket 306 improves the sealing performance of the water-stop plate 305, preventing water leakage.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
