Detailed Description

As shown in figure 1, a quick connection structure comprises a fastener 1, a water outlet pipe head 2 and a connecting pipe 4, wherein the fastener 1 is made of elastic plastic, a fixing lug 11 is arranged on the inner wall of the fastener 1, and slits 13 are respectively arranged on the fasteners 1 on two sides of the fixing lug 11, so that the elastic space and the capacity are improved. The water outlet pipe head 2 is provided with notches 21, the number of the fixing lugs 11 is at least 2, and the fixing lugs are oppositely arranged on the inner wall of the fastener 1; the notches 21 correspond to the fixing projections 11 one by one, and are kept relatively stable. Be equipped with recess 41 on the outer wall of connecting pipe 4, cup jointed sealing washer 3 on recess 41 one side, go out water tube head 2 and cup joint on connecting pipe 4, fixed lug 11 can penetrate in notch 21 and joint in recess 41 from going out the water tube head 2 outside, and fixed lug 11 can carry out 360 degrees rotations around connecting pipe 4 in recess 41. Further, still be equipped with relative positioning groove 12 on the fastener 1 inner wall, be equipped with on the outer wall of play water tube head 2 and can with positioning step 22 of positioning groove 12 joint for guarantee relative location after fastener 1 is connected with play water tube head 2, improve the reliability.

As shown in fig. 1, a quick connection structure, when using, the recess 41 is used for installing the sealing ring 3 and is used for positioning the fixed lug 11 in the fastener 1, the fixed lug 11 can take place elastic deformation under the effect of radial force and make the fixed lug 11 outwards expand to flush with the inner circle, it is convenient for the water outlet pipe head 2 and the connecting pipe 4 to insert, during using, assemble the fastener 1 on the water outlet pipe head 2 at first, make the fixed lug 11 stretch into the notch 21, the connecting pipe 4 that the cover has the sealing ring 3 can be directly inserted into the water outlet pipe head 2, then the fixed lug 11 can be buckled into the recess 41 of the connecting pipe 4, under the effect of the sealing ring 3, this combination can seal the connecting pipe 4 of the sealing ring 3, and the connecting pipe 4 can carry out 360 degrees rotations in the water outlet pipe head 2. When the connecting pipe 4 needs to be disassembled, the fastener 1 can be rotated, the fixing lug 11 is outwards expanded to be flush with the inner circle of the fastener 1 under the action of elastic force, and then the connecting pipe 4 can be freely pulled out and disassembled.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
