Detailed Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate on the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative labor all fall within the protection scope of the present utility model.

[0022] The following describes the specific embodiments of the present utility model with reference to the drawings.

[0023] As Figures 1 to 4 shown, a quick connector assembly includes a connector body 1 integrally provided or fixed to a faucet and a quick connector 2 threadedly connected to the connector body 1. A convex ring 3 is provided outside the connector body 1. The quick connector 2 includes a tube body 4 with an internal threaded hole and a hook 5 provided outside the tube body 4. The hook 5 includes a handle section 6 inclined towards the tube body 4. A V-shaped connecting section 7 is provided between the handle section 6 and the tube body 4. The upper end of the handle section 6 has a protrusion 8 that can be placed on the convex ring 3. In this embodiment, the quick connector 2 is made of plastic, and the connector body 1 can be made of plastic or metal material. How the quick connector 2 is connected to the water inlet pipe of a washing machine or a dishwasher is not an improvement point of this application and can be integrally formed or in other forms, which is the prior art and thus will not be specifically elaborated.

[0024] Working principle: The hook 5 of the quick connector 2 is placed on the convex ring 3 of the connector body 1 to prevent the thread from loosening due to vibration, ensuring stable and reliable connection and guaranteeing the sealing performance. When in use, the handle section 6 is pulled outwards, the V-shaped angle between the connecting parts becomes larger. After the quick connector 2 is screwed onto the connector body 1, the handle section 6 is released, and the connecting parts recover their deformation so that the protrusion 8 at the upper end of the handle section 6 is placed on the convex ring 3. In this embodiment, the connector body 1 can be made of metal or plastic, and the plastic quick connector 2 can be used in cooperation with the metal connector body 1. When used in cooperation with the metal connector body 1, the handle section 6 moves in a direction away from the tube body 4 and stops moving when the other end of the abutting section 9 abuts against the stop block 10. After the handle section 6 is released, the magnet on the protrusion 8 of the handle section 6 attracts the convex ring 3 or directly places on the convex ring 3; when the plastic quick connector 2 is used in cooperation with the plastic connector body 1, the operation method is the same, and finally the lower end of the protrusion 8 abuts against the upper surface of the convex ring 3.

[0025] There is a distance between the connecting section 7 and the lower part of the handle section 6. The lower part of the handle section 6 is provided with an abutting section 9 located below the connecting section 7. The lower part of the tube body 4 is provided with a stop block 10 corresponding to the position of the abutting section 9. There is a movable distance between the abutting section 9 and the stop block 10, which plays a limiting role. When the abutting section 9 contacts the stop block 10, the position of the handle section 6 is adjusted in place.

[0026] An annular mounting portion 11 is radially provided on the outer wall of the pipe body 4, and the inner end of the connecting section 7 of the hook 5 is connected to the annular mounting portion 11.

[0027] Two hooks 5 are provided and symmetrically arranged on both sides of the pipe body 4. It is also possible that three hooks 5 are arranged at equal intervals along the circumferential direction on the outer wall of the pipe body 4.

[0028] The joint body 1 includes an upper connecting portion 12 and a lower connecting portion 13. A channel hole 14 is provided in the joint body 1. An internal threaded hole is provided in the upper connecting portion 12. At least the lower end portion of the lower connecting portion 13 is provided with an external thread, and the convex ring 3 is fixed to the lower connecting portion 13.

[0029] A limiting step 15 is formed at the connection between the upper connecting portion 12 and the lower connecting portion 13. The convex ring 3 is sleeved on the lower connecting portion 13 and the upper end surface of the convex ring 3 abuts against the limiting step 15. A snap spring 16 for abutting the convex ring 3 against the limiting step 15 is provided on the outer wall of the lower connecting portion 13.

[0030] A through hole 17 adapted to the shape of the lower connecting portion 13 and a first annular groove 18 coaxial with the through hole 17 are provided at the center of the convex ring 3. The diameter of the first annular groove 18 is larger than the diameter of the through hole 17. A second annular groove 19 is provided at the position corresponding to the first annular groove 18 on the outer wall of the lower connecting portion 13. The snap spring 16 is embedded in the second annular groove 19. In this embodiment, the height of the annular groove is at least 1 / 3 of the height of the through hole 17. This is preferred, and it can also be lower than 1 / 3 as long as a yielding space is provided to facilitate the fixing of the convex ring 3 by the snap spring 16.
