Detailed Description

The following will be described in connection with the embodiments of the present invention to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 3 to 6, the quick-connect structure for a washing pipe interface of the present embodiment includes a washing pipe 20 and a quick-connect coupling 10 coupled to the washing pipe 20, wherein the quick-connect coupling 10 includes a coupling body 19, an inner sealing ring 18, an outer sealing ring 17, a locking ring 16, an unlocking ring 15, a sealing ring holder 14, a locking ring washer 13 and a locking ring base 12. The outer end of the joint body 19 is provided with a water outlet 191, and the inner end of the joint body is of an open structure. The inner side sealing ring 18, the sealing ring support 14 and the outer side sealing ring 17 are sequentially arranged in an inner cavity of the joint body 19 from an outer end close to the water outlet 191 to an inner end far away from the water outlet 191, the outer side sealing ring 17 is sleeved on the inner wall of the sealing ring support 14, and an interface end 171 matched with the washing pipeline 20 is arranged at the end part of the outer side sealing ring 17. The lock ring 16 is installed in the lock ring gasket 23, the lock ring gasket 13 is sleeved in the lock ring base 12, the front end of the lock ring base 12 is fixedly matched with the inner end inner wall of the joint body 19, the unlocking ring 15 extends into the lock ring base 12 from the rear end of the lock ring base 12, the front end of the unlocking ring 15 is matched with the lock ring 16, and the front end of the washing pipeline 10 sequentially penetrates through the unlocking ring 15 and the lock ring 16 to be in sealing fit with the interface end 171 of the outer side sealing ring 17.

The quick-insertion structure of the embodiment adopts structural schemes of self-locking, unlocking, sealing rings and the like. The fast inserting structure of the embodiment is formed by inserting the washing pipeline and the fast inserting connector in the axial direction, the washing pipeline is contacted and extruded with the outer sealing ring after being inserted, a sealing state is achieved, and meanwhile, the locking ring is interfered with the washing pipeline, so that the existing sealing position is kept; when the pipeline is pulled out, the self-locking state of the locking ring and the washing pipeline is released by pressing the unlocking ring, the washing pipeline can be pulled out smoothly, and the device can be applied to various vehicle types.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
